Author | Li Lan

Edit | Chapter Ripple

On March 30, three years ago, officer Lei announced to build a car. One hundred days later, Xiaomi led nearly 20 supply chain manufacturers such as Zongmu Technology, a smart driving solution provider.
As one of the first companies to invest and bet after Xiaomi entered the car, on March 28, 2024,On the day when Xiaomi’s first car, SU7, went public, Zongmu Technology also formally submitted a prospectus to the Hong Kong Stock Exchange, intending to list the main board.
This is the third listing of Zongmu Technology.
In January 2017, Zongmu Technology was listed on the New Third Board and delisted in December of the same year. The reason given was "needed for the adjustment of the company’s operation and development strategy".
In November 2022, Zongmu Technology science and technology innovation board’s IPO application was accepted by the Shanghai Stock Exchange, and it planned to raise 2 billion yuan, but in September 2023, it chose to withdraw its listing application in science and technology innovation board.
Now,Vertical scientific and technological choiceGive up science and technology innovation board and launch a sprint to the Hong Kong Stock Exchange.
fromAccording to the prospectus,Zongmu Technology has been more cautious in its wording this time, and put more emphasis on products. At the same time, before applying for IPO, it also carried out a series of "light" actions.
asThe "veteran" who broke into the capital market for the third time doesn’t know.Can the listing of Zongmu Technology go smoothly this time?
01
The financial report has improved, and the business is exploring.
The most eye-catching part of the prospectus is that the gross profit margin has finally turned positive.
Compared with the unprofitable situation in November 2022, Zongmu Technology has achieved a positive gross profit margin. From 2021 to 2023, Zongmu Technology’s gross profit margin was -8.9%, -3.5% and 3.5%, respectively, corresponding to a gross profit of-20.07 million yuan,-16.29 million yuan and a profit of 17.33 million yuan. Revenue has a steady growth with a compound annual growth rate of 48.7%.

Moreover, the cash flow of Zongmu Technology has also become stable. According to the prospectus, there is still a lot of room for fault tolerance. As of January 31, 2024, Zongmu Technology had 33.2 million yuan in cash assets, leaving 1.19 billion yuan in unused bank facilities.
How did Zongmu Technology achieve "rebirth"?A lot of factors benefit from the continuous growth of the market as a whole.
Before the real commercialization of L4 comes, L2+ has the widest application prospect, among which, the "integrated operation and parking" has the highest cost performance. According to the monitoring data of the Institute of Advanced Technology Intelligent Automobile, in 2023, 3,504,800 new cars with automatic parking were delivered as standard in China market (excluding import and export), up by 22.10% year-on-year.
According to the data in the prospectus, in 2022, about 20% of the ADAS solution market for passenger cars in China will be automatic parking. Among them, APA solutions account for more than 80%. Based on the corresponding income in 2022, Zongmu Technology is the second in China and the first in China respectively.
At present, most parking and parking integrated solutions in the market are actually designed and integrated based on the 1.0 architecture, which simply combines the driving SoC and the parking SoC into one box. The biggest technical moat of technology is that only a single SoC can solve the two problems of parking and parking.
Although three of the top five automatic parking APA schemes are foreign suppliers,However, domestic suppliers have the advantage of being "close to the water", which is convenient to provide personalized customized services to domestic new energy vehicle enterprises. The market share of domestic suppliers has increased from less than 5% in 2018 to 16.7% in 2022, and it is expected to exceed 25.0% in 2027..

According to the data of burning knowledge consulting, in terms of sales revenue in 2022, the ranking of the company among mainland suppliers in China is as follows: Zongmu Technology ranks fifth in the ADAS market with a market share of 1.0%; Ranked second in the automatic parking solution market, with a market share of 4.9%; Ranked first in APA parking solution market, with a market share of 5.6%.
According to the prospectus,AVP and APA platforms have been used in 28 models, and the energy service robot for intelligent mobile energy solutions is equipped with L4-level autopilot function supported by Drop’nGo platform..
From the most basic composition, the products of Zongmu Technology can be divided into two main directions:First, intelligent driving hardware and solutions, including domain controller and camera, 4D millimeter-wave radar, ultrasonic radar and other gauge sensors; Second, provide research and development services related to autonomous driving.
The hardware part is divided into three products,That is, panoramic surveillance camera, automatic parking assistance function and autonomous parking function, which respectively correspond to three scenes: car panoramic "reversing radar", automatic parking in the car and remote parking outside the car..
A domain controller is a computer that manages specific vehicle functions or fields, such as active safety, automatic driving, parking or parking. The controller of Zongmu Science and Technology Domain collects data from sensors around the vehicle (including radar, camera and ultrasonic sensor) to build a model of the surrounding environment. The software algorithm embedded in the domain controller will then determine the appropriate action of the vehicle according to the model. Moreover, Zongmu Technology has also developed a separate software algorithm, which can be delivered as a comprehensive software embedded hardware product or as an independent software product.
Finally, the computing platform of Zongmu Technology provides the basis for all function iterations, and the Drop’nGo platform supports the development of intelligent driving functions from L0 to L4.
According to the prospectus, since its launch in 2017, the Drop’nGo platform has gone through several iterations, enhancing its multi-sensor data fusion capability, improving its adaptability to weather and lighting conditions, and expanding its application scenarios from indoor to outdoor.
The third generation of Drop’nGo platform can provide L2+ comprehensive intelligent parking function on passenger cars, and further empower energy solutions with L4 automatic driving function.
The hardware that science and technology can make money has changed year by year.
In December 2022, in the prospectus of Zongmu Technology,Describing himself as "one of the few first-class suppliers in China that can provide intelligent driving systems for automobiles, including L0-L4 intelligent driving control units and intelligent sensors", the importance attached to control units has declined.
From the perspective of income structure, Zongmu Technology mainly relied on car trajectory sensors for profit last year.
At present, the domestic self-driving auto market dominated by L2+ level still needs the second-gear APA integrated parking solution. According to the prospectus, the company is in a leading position in the market of ADAS, automatic parking and APA (automatic parking assistance system) parking solutions.

From the perspective of profitability, the highest gross profit margin is the R&D services related to autonomous driving. In 2021 and 2022, the gross profit margin reached 42.7% and 50.8% respectively. However, in 2023, there was a waist cut, only 18.6%. Looking at the technology, it is pointed out that this is mainly due to the increasingly fierce market competition and the increase in project complexity, resulting in increased costs.
From the data of the prospectus alone, although Zongmu Technology does not have much exponential growth, it still has extraordinary incremental space.

Moreover, there are more choices when getting through the depth of customers. As of December, 2022, the overall customer matrix is still relatively simple. Among them, Cyrus accounts for more than 50% of the revenue, and the top five customers account for nearly 90%. By 2023, the number one customer has dropped to 43.8%, the customer diversity has increased, and the ability to resist risks has also been significantly enhanced.
Zongmu Technology is also constantly adjusting its customer service mode, and the autonomous driving R&D service has received a large order. In December 2023, it successfully obtained the Amphiman 3000 fixed-point from Changan Automobile to support its new car platform for a series of models, and it is expected to be mass-produced in 2024.

However, Zongmu Technology is still at a loss.

From 2021 to 2023, the net losses of Zongmu Technology were 434 million yuan, 588 million yuan and 564 million yuan respectively, and the adjusted net losses were 382 million yuan, 477 million yuan and 516 million yuan respectively.The total net loss for three years exceeded 1.3 billion yuan.
Of course, Zongmu Technology also has an explanation for this persistent loss.Even similar to the contents in the prospectus required for listing in science and technology innovation board in 2022, the chip is too expensive.
According to Zongmu Technology,With the overcapacity of global chips, this adverse impact on costs will be significantly reduced in the future. After all, whether it is hardware upgrade or solution iteration, the core need is computing power..
02
High-profile financing, multiple IPOs
Zongmu technology has always been highly anticipated by the capital market.
In the latest shareholding structure, Hong Kong Zongmu is the largest shareholder of the company, holding 22.17% of the shares. As a concerted action, Tang Rui and his mother Li Xiaoling control 33.3% of the shares of the company through multiple entities. In addition, Junlian Capital holds 7.55% of the shares as the second largest shareholder, while Xiaomi Group, which has received much attention, ranks the fifth largest shareholder with 4.73% of the shares.

The earliest round of financing record of Zongmu Technology occurred in 2015. In the previous year, in 2014, Mobileye, the world’s largest ADAS manufacturer, landed on the New York Stock Exchange, which means that the track of ADAS has been verified and opened a financing channel for Zongmu Technology, which is on the same track.
In June, 2021, Zongmu Technology announced the formal completion of Series D financing with a cumulative amount of $190 million.. Among them, the D3 round was led by Xiaomi Changjiang Industrial Fund, and the investors included Fosun Chuangfu, Langtai Capital, Shanghai Kechuang, Industrial Bank, strategic investors Changan Automobile and Coboda Investment.
Zongmu Technology completed 9 rounds of financing before IPO, and the accumulated subscription amount reached 2.247 billion yuan. Among them, in the E round of financing in March 2022, Zongmu Technology raised 867 million yuan at the subscription price of 93.56 yuan/share, and the company’s valuation exceeded 9 billion yuan.
However, the financing journey of Zongmu Technology is always interrupted for various reasons..
Zongmu used to be very close to listing. On January 19th, 2017, Zongmu Technology was approved to be listed on the National Small and Medium Enterprise Share Transfer System (NEEQ) with the stock code of 870816. However, "considering the business strategy and compliance cost at that time, we adjusted the future development strategy". Less than one year later, Zongmu Technology completed the termination of listing on December 11th, 2017.
The vigorous Shanghai Stock Exchange in 2022 has almost become a reality. However, in the end, due to the development strategy and other reasons, Zongmu Technology voluntarily withdrew its previous A-share listing application, and the withdrawal was officially accepted on September 27, 2023.
In the meantime,There is also news from the pulse that Zongmu Technology has a saying that the salary of fresh graduates will be reduced by 20%.

It may be that the road to listing is not smooth and the top management has fluctuated.In February 2024,CTO Wang Fan joined Beidou Zhilian, and Wang Fan was one of the four core executives of Zongmu Technology. He started to build the Beijing Autopilot R&D Center, and completed the research and development of AVP1.0 in Zongmu Technology in 2017.
Fortunately, the new employee was the original team, and he was replaced by Jiang Weiping. He joined Zongmu Technology as early as 2013, and had previously worked in CSR Semiconductor Company and NVIDIA. Later, he left Zongmu Technology due to infighting and did not return to Zongmu until the end of 2022.
03
Go to the new track
On the premise that the APA market is saturated, Zongmu Technology tries to go further to the charging robot track.
In 2023, nearly 65% of Zongmu Technology’s revenue sources are car gauge sensors. Compared with technology companies, Zongmu Technology is more like a manufacturing enterprise. This may come from another manufacturing attribute of the founder, Tang Rui, CEO, who also founded Can Cong Robot.
In the official LinkedIn,The latest position of Zongmu Technology is the on-site operation and maintenance engineer of intelligent energy storage charging robot, and some positions are in Ningbo, mainly in Shanghai.

In late January of this year, Zongmu Technology and Can Cong Science and Technology launched the charging treasure in the automatic driving field and the low-speed fully automatic driving charging robot FlashBot. According to the prospectus,The first generation of FlashBot is equipped with 104 kWh storage capacity, which is one of the robots with the highest storage capacity among all L4-class self-driving energy service robots developed in the world.
Tang Rui said, "Can Cong robots are building a highly flexible mobile energy network to promote energy trading in a larger space-time range." At the application level, the most intuitive embodiment is to save electricity and money.
In December last year, two Flashbot were put into commercial operation in Zhangjiang Park, and an average of 272 kwh of electricity was purchased from the local microgrid every day, of which 185 kwh was sold back to the microgrid, and 87.5 kwh was used to provide charging service for new energy vehicles, with an average daily cycle of 2.6 times, which brought more than 12,000 yuan in income in that month, that is, the average daily net income of each device was close to that of 200 yuan.
Before the robot officially appeared, Zongmu Technology had actually been laying out its energy business.Zongmu Technology has also designed a set of SaaS software and a DragonNet program to maintain on-site operation. If the charging robot of Zongmu Technology can be commercialized, it may make some changes in the charging pile scene.
According to the data in the prospectus, from 2021 to 2023, the sales revenue of Zongmu Technology from wireless charging equipment and accessories for new energy vehicles was 129,000 yuan, 11.357 million yuan and 437,000 yuan respectively.
In addition, as an "external charging treasure" loaded with sensors, Flashbot is also a part of the flywheel that I hope to build. The energy service robot conducts algorithm training in different driving cases, and then gives data support to the ADAS car-level hardware.
Looking at the highlights of this reorganization of business, Zongmu Technology began to break through into more subdivided markets, and may be able to complete the listing more lightly. At that time, it will be the third listed company in the Xiaomi automobile industry chain after Sagitar and Hesai.

"Car shock" is a fashion culture. JASON ZHANG explodes and Li Xiaoran is very strong.

  Movie network news (Photo/Shanghai Film Festival Reporting Group) From the beginning, most of JASON ZHANG’s films chose the theme of urban love. In an exclusive interview with [Movie Network], he admitted that he really prefers to tell stories from the emotional point of view. The film "Driverless" involves many sensitive issues such as "car shock", one-night stand, love triangle and so on. "‘ Che Zhen ’ It is everywhere in life, and I think it is already part of the car culture. " As a director, JASON ZHANG is very satisfied with the performances of the leading actors in the film, especially Li Xiaoran, who has successfully created a role that seems to be a good wife and a good mother but has an unspeakable past. Recently, Li Xiaoran’s boyfriend Yan Po was chopped by the black forces. According to JASON ZHANG, Li Xiaoran, who has a strong personality, is optimistic and calm in the face of all this.

Talking about the film: "Car shock" is an extramarital affair in automobile culture, which is very common.

  Many plots in JASON ZHANG’s films are based on real events in life, and emotional themes such as marriage are the best entry point for him to reflect real life. "The theme that reflects trivial things in life is not attractive to me. I prefer to go deep into people’s emotions or human nature." In "Unmanned Driving", JASON ZHANG used a variety of phenomena to express people’s emotional state in reality, such as "car shock", one-night stand, multi-angle love and so on. Although these contents are still abnormal in some people’s eyes, JASON ZHANG’s view is quite different.

  "In the past, I may think that love triangle and extramarital affairs are very important things, but now I think these are very common things, even five-corner love, and many people’s emotions are intertwined." JASON ZHANG also admitted that great changes have taken place in today’s concept of love and morality, but people are still pursuing pure love in their bones, just like Huang Xuan and Wang Luodan in the play, one represents a young man who is constantly pursuing material things, and the other is a simple Sargam. In order to better show the theme, JASON ZHANG specially set up a scene of "car shock" for them. "In fact, this thing is everywhere in life, and I think it is already a car culture. JASON ZHANG also revealed that a scene in which two people "play car shock" in a funny way while watching a movie at the drive-in cinema has been deleted because of the length of the film.

Comment on Actor: Wang Luodan is very simple. Li Xiaoran faces everything with a smile.

  In Driverless, Gao Yuanyuan and Liu Ye staged a "one-night stand", Wang Luodan abandoned his "chatty" image and played Sargam. Li Xiaoran’s role seems to be a good wife and mother but has an unspeakable past, and every actor has a great change. "Wang Luodan still represents a very simple person, and those pure things in her are quite attractive to me. In fact, every actor in the film is different from the past.

  JASON ZHANG was full of praise for Li Xiaoran’s performance in the film, saying that his performance was the most successful. Recently, her boyfriend Yan Po was chopped by the black forces. JASON ZHANG revealed that Li Xiaoran was very rational in the face of the accident. "She is a very strong person. When we sat together and chatted, she told me the situation calmly, including some details. I think these are related to her strong personality. She is still optimistic and can face it with a smile."

On genre: there is no living space for literary films, and many films are not suitable for 3D technology.

  The topic of "Car Shock" was first chosen in the promotion of "Unmanned Driving", and then the "bed photos" of Liu Ye and Gao Yuanyuan were exposed. Sensitive topics such as one-night stand often appeared in the promotion of the film. JASON ZHANG, who used to shoot literary films, admitted that he did not reject the commercial operation. "In fact, it was a helpless move. Many literary films had no room for survival in the China film market, even those small films that did not intend to win much.

  In addition to imitating the blockbuster mode regardless of the size of the film, the use of a large number of 3D technologies has become a trend. However, JASON ZHANG bluntly said that many films are not suitable for co-production into 3D versions. "3D is only a technical means. Whether the film is adopted or not depends on the type. It is more appropriate for action movies or cartoons to pursue visual effects, but it is completely unnecessary for movies with realistic themes." This type of film is what Zhang Yang is good at. He revealed that his next film is already in the process of planning, and it is still an urban theme.

3. Most of them occur in rural areas;

4. Most of them occur in the process of students playing together;

5. Most of them occur in primary school students and junior high school students, and most of them are boys.

NO.2 "six noes" for preventing drowning

1. Do not swim in the water without permission;

2. Do not swim with others without authorization;

3. Do not swim without parents or teachers;

4. Do not swim in the waters without safety facilities and ambulance personnel;

5. Do not swim in unfamiliar waters;

6. Students who are not familiar with water are not allowed to go into the water for rescue.

NO.3 drowning prevention measures

1. Swimming should be led by adults;

2. Don’t play alone by the river or the mountain pond;

3. If floating objects such as foam blocks, lifebuoys and wooden blocks can be found at the scene, they can be thrown to the drowning person to prevent the drowning person from sinking into the water;

4. If there are no bamboo poles, floating objects, etc. at the scene, you can take off your clothes and connect them as a rope and throw them to the drowning person. Remember to lie on the ground to ensure your own safety.

Here, we also propose to the general public:

The weather is getting hotter and hotter. I hope all citizens and friends will pay attention to it at any time. If you find minors (especially small boys in groups of three or five) swimming, splashing and playing in ponds, rivers, reservoirs and other places without guardians, please stop them in time! Action by the whole people, starting from you and me and starting from the side!

Let’s act together,

Cherish life and prevent drowning, starting from me!

The intersection of Beihuan Avenue and Shangbu Interchange was closed for 135 days.

The reporter learned from the Shenzhen Municipal Communications Commission that from now on, the intersection of the main road of Beihuan Avenue and Shangbu Interchange will be closed until January 9 next year to make way for the accelerated construction of the Banyin Passage. The Shenzhen Municipal Communications Commission announced on October 15th that the Banyin Channel Project is expected to be completed by the end of next year according to the current progress of the project.

General plan renderings of Banyin Channel

It is understood that the Banyin Passage Project starts from the north side of Huangmugang Interchange in the south and is arranged along the west side of Beihuan Avenue via Nigang Interchange in the north. After crossing Beihuan Avenue, it crosses Jinhu Reservoir by sinking the tunnel, continues to cross Yinhu Road into Jigongshan, crosses xiamen-shenzhen railway Meilin Tunnel, crosses Nanping Expressway after leaving the tunnel, connects Banxuegang Avenue to the north, and finally reaches the intersection of Huancheng South Road. The main line is 10.7 kilometers long. A new Jigongshan tunnel (with a total length of 8,856 meters on the left and right lines) and an interchange at the North Ring Road will be built, and two interchanges at Nigang North Ring Road and Nanping Banxuegang will be rebuilt.

Present situation of the intersection of Beihuan Avenue and Shangbu Interchange

In order to smoothly promote the construction of Banyin Passage, from now on, the five lanes of the main road in Yinhu section of Beihuan Avenue (eastbound) will be adjusted to three lanes, and the one-lane auxiliary road will be adjusted to two lanes. The three eastbound main lanes can only go to Nigang East Road (Buji direction), and the original main lane of North Ring Road will be closed to Shangbu Road and Nigang West Road (Huafu Road). The closing time is expected to be January 9 next year. Vehicles passing through this section can turn at Huanggang Interchange to the auxiliary road of Beijiashan Waterworks (eastbound), and take the right auxiliary road at Yinhu exit of Beihuan Avenue (eastbound) or other surrounding roads.

Regarding the progress of the construction of the Banyin Channel, which the public is most concerned about, the Shenzhen Municipal Communications Commission revealed that as of October 15, there were 59 cast-in-place box girders in the superstructure of the Banyin Channel Bridge, 32 of which have been completed, and 54.2% have been completed; There are 18 steel box girders, 6 of which have been completed, accounting for 33.3%.

On October 15th, the Municipal Communications Commission released a message saying that recently, the main road surface of Binhe Avenue pavement repair and traffic improvement project was completed and opened to traffic. At present, the construction of auxiliary roads and sidewalks is stepping up. The Municipal Transportation Facilities Bureau made full use of the Mid-Autumn Festival and National Day holidays, increased the input of resources, overcame the impact of the strong typhoon on the construction, and organized the contractors to concentrate on completing the asphalt paving of the main roads on the north and south sides. Considering the huge traffic flow on Binhe Avenue, the asphalt paving operation time is night construction (from 22: 00 to 6: 00 the next day).

It is reported that the total length of Binhe Avenue is about 9.975 kilometers, from Guangzhou-Shenzhen Expressway Interchange to Baoan South Road, which is an important east-west expressway in Shenzhen. Affected by the construction of Chunfeng Tunnel, the actual improved section is the Guangzhou-Shenzhen Expressway Interchange Shangbu Interchange, with a length of about 8.6 kilometers.

The construction contents of Binhe Avenue pavement repair and traffic improvement project mainly include: replacing the central collision wall of the road, transforming the mud concrete pavement into asphalt concrete pavement, so as to achieve the effects of environmental protection, noise reduction and improving driving comfort, and upgrading the road slow-moving system, including improving the facilities such as sidewalks and bicycle lanes. At present, the construction is progressing smoothly, and the auxiliary roads and sidewalks are being stepped up. (Shenzhen Evening News reporter Dong Yuhan)

"The hero is sad at Meilin Pass" will become history! Good news came from the second phase of Metro Line 6

There is a popular saying in Shenzhen: "Heroes feel sad about Meilin Pass", but this sentence may become history in 2020. There is good news from the second phase of Line 6, and you can understand it by looking at the picture.

What is a digital video camera?

What is a digital video camera?

  Digital Video camera is DV, which is the abbreviation of Digital Video. Translated into Chinese, it means "Digital Video". It is a digital video format jointly developed by many famous home appliance giants such as Sony, Panasonic, Shengli, Sharp, Toshiba and Canon. However, in the joint development of a digital video format. However, in most cases, DV stands for digital camera. According to the purpose of use, it can be divided into: broadcast-grade models, professional-grade models and consumer-grade models. According to the storage medium, it can be divided into: magnetic tape type, optical disk type, hard disk type and memory card type.

Development course of digital camera

  It has been 16 years since the first digital camera was born in 2011. During these 16 years, digital cameras have undergone tremendous changes. The storage media range from DV to DVD to hard disk, with a total pixel of 800,000 to 5 million, and the image quality ranges from standard-definition DV(720×576) to high-definition HDV(1920×1080).

The first DV camera was born in 1995.

  In July, 1995, Sony released the first DV camera DCR-VX1000. Once released, DCR-VX1000 was widely adopted by TV journalists and producers all over the world. This product uses Mini-DV format tape, adopts 3CCD sensor (3 1/3 inch, 410,000 pixel CCD), 10x optical zoom and optical anti-shake system, and the price at the time of release is as high as 4,000 yuan. DCR-VX1000 is a major change in the history of imaging. Since then, civil digital cameras have entered the digital age.

Sony DCR-VX1000, the first DV camera

The first DVD camera was born in 2000.

  In August 2000, Hitachi introduced the first DVD camera DZ-MV100. At that time, this product could only be recorded by DVD-RAM. Hitachi first brought DVD as a storage medium into a digital camera, and used an 8cm DVD-RAM burning disc as a storage medium, which got rid of the inconvenience of DV tape and was a major innovation after DV camera. However, at that time, not many people paid attention to this product. DZ-MV100 was only sold in Japan, and it was hard to find a trace in the domestic market. It was recognized that DVD cameras should be widely promoted by Sony three years later.

The first DVD camera DZ-MV100

In 2004, the first micro hard disk camera was born.

  In September, 2004, JVC launched the first batch of 1-inch micro hard disk cameras MC200 and MC100, and the hard disk began to enter the field of consumer digital cameras. The capacity of the two hard disks is 4GB, and the video images taken are compressed by MPEG-2, so users can flexibly change the compression rate to extend the shooting time. The adoption of hard disk media makes it extremely convenient for digital cameras to exchange information with computers. Both MC200 and MC100 and several subsequent 1-inch micro hard disk cameras can flexibly replace micro hard disks. By June, 2005, JVC released the Everio G series with 1.8-inch high-capacity hard disk camera. The maximum capacity reached 30GB, and the volume was well controlled, and the price remained at the level of similar DV cameras.

The first micro hard disk camera JVC MC200

In 2004, the first HDV 1080i HD camera was born.

  In September 2003, Sony, Canon, Sharp and JVC jointly formulated the HD camera standard HDV. In September 2004, Sony released the first HDV 1080i high-definition camera HDR-FX1E. The recording resolution of HDV reached 1440×1080, and the horizontal scanning line was doubled compared with that of DVD, and the definition was revolutionized. HDR-FX1E, including the HDV cameras introduced later, used the original ones.

The first HDV 1080i HD camera HDR-FX1E

In 2010, the first 3D camera was born.

  Up to now, the 3D revolution has all revolved around Hollywood blockbusters and major sports events. With the advent of Panasonic HDC-SDT750 3D camera, this technology is one step closer to home users. Panasonic HDC-SDT750 is the world’s first 3D camera. After the launch of this camera, we can capture every unforgettable moment of life with 3D lens in the future, such as children’s first step, university graduation celebration and so on. Panasonic released the HDC-SDT750 3D camera on July 28th, 2010. The official price is RMB 11,998 (excluding 3D lens). It is designed with dual lenses and equipped with Panasonic’s high-end series of 3mos image sensors. (What is a 3D camera? )

Working principle of digital camera

  The basic principle of digital camera is simply the transformation and transmission of optical-electrical-digital signals. That is to say, the light signal is converted into current through the photosensitive element, and then the analog electric signal is converted into digital signal, and the information obtained after processing and filtering by a special chip is restored to be the dynamic picture we see.

  The photosensitive element of digital video camera can convert light into charge, which is converted into digital signal through analog-to-digital converter chip. There are two main types: one is widely used CCD (Charge Coupled Device); The other is CMOS (complementary metal oxide conductor) device.

  Characteristics of digital camera

  High-definition analog cameras record analog signals, so the image definition (also called resolution, resolution or resolution) is not high. For example, the horizontal definition of VHS cameras is mainly 240 lines, and it is best to mention that Hi8 models only have 400 lines. DV records digital signals, and its horizontal resolution has reached 500~540 lines, which can be comparable to professional cameras.

  The bandwidth of chroma and brightness signal of DV is almost six times that of analog camera, and the bandwidth of chroma and brightness is one of the most important factors that determine the image quality, so the color of the image shot by DV is more pure and gorgeous, and it has reached the level of professional camera.

  The signal recorded on the lossless reproduction DV tape can be transcribed countless times, and the image quality will not be degraded at all, which is beyond the reach of analog cameras.

  Small size and light weight Compared with analog cameras, the size of DV cameras is greatly reduced, generally only about 123mm×87mm×66mm, and the weight is greatly reduced, generally only about 500 grams, which greatly facilitates the users’ size is only 74.7mm×61.9mm×26.9mm and the weight is only 90 grams, which is even lighter than most mobile phones.

Digital camera classification

  I. Classification according to the purpose of use

  1. Broadcast-grade models:

  These models are mainly used in the field of radio and television, with high image quality and comprehensive performance, but with higher price and larger volume, they have the highest definition, the largest signal-to-noise ratio and the best image quality. Of course, the price of several hundred thousand yuan is not acceptable to ordinary people. For example, Panasonic AJ-HPX3100MC and other models.

Classification of digital cameras-broadcast-class models

  2, professional models:

  These models are generally used in professional TV fields other than radio and television, such as audio-visual education, and the image quality is lower than that of broadcast cameras. However, in recent years, some high-end professional cameras have surpassed the old models of broadcast cameras in many aspects, such as performance indicators, and the price is generally between tens of thousands and hundreds of thousands of yuan.

  Compared with consumer models, professional DV is not only cooler and more eye-catching, but also much higher in configuration, such as the use of lenses with better quality performance and the larger size of CCD, which is more prominent in imaging quality and adaptability to the environment. For friends who pursue image quality, the surprise brought by the improvement of image quality can’t be measured by money at all. Such as Sony’s HXR-NX5, the price is around 34,000.

Classification of Digital Cameras-Professional Models

  3. Consumer-grade models:

  This type of camera is mainly suitable for home use, and it is used in non-business occasions with low image quality requirements, such as home entertainment, etc. This type of camera is small in size, light in weight, easy to carry, simple in operation and cheap in price. It can be used to make VCD and DVD of personal family in occasions with low requirements, and the price is generally in the order of several thousand yuan to ten thousand yuan. Such as Sony’s HDR-XR160E.

Classification of digital cameras-consumer models

  If we subdivide the home digital cameras, they can be roughly divided into the following categories: entry-level DV, mid-range consumer-grade DV and high-end quasi-professional DV products.

  Second, according to the classification of storage media

  1, tape type:

  Refers to the digital video camera with Mini DV as the recording medium, which was first developed by more than 10 manufacturers in 1994. Record high-quality digital video signals through a 1/4 inch metal vapor deposition tape.

  2, CD-ROM:

  Refers to the DVD digital camera, the storage medium is DVD-R, DVR+R, or DVD-RW, DVD+RW to store dynamic video images, which is simple to operate and easy to carry, and there is no need to worry about overlapping shooting during shooting, let alone wasting time to rewind or play back, especially it can be played immediately through the DVD player, which saves the trouble of post-editing.

  DVD media has the highest security and stability among all media digital cameras at present. It is neither as easy to wear and tear as tape DV, nor as demanding as hard disk DV for shock prevention. The disadvantage is that the price of DVD is slightly higher than that of tape DV, and the time for recording is relatively short.

  3, hard disk:

  Refers to a digital video camera that uses a hard disk as a storage medium. It was first introduced by JVC in 2005, using micro hard disk as storage medium.

  Hard disk cameras have many advantages, and large-capacity hard disk cameras can ensure long-term shooting, so that you will not have any worries when traveling. When you get home, you can transfer the shooting materials to the computer, and you no longer need the complicated and professional video acquisition equipment as in the era of MiniDV tape camera. You can easily export the materials just by connecting with the computer through USB cable, so that ordinary family users can easily experience the fun of shooting and editing video films.

  Like CF card, micro hard disk is smaller than DVD, and its service time is the most impressive among many storage media. However, due to the short time of hard disk DV, there are still many shortcomings, such as poor shock resistance and so on. With the further decline of prices, the number of people in need will inevitably increase in the future.

  4. Memory card type:

  Refers to the digital video camera using memory card as storage medium, such as the popular "X Easy Shooting" product. As a transitional simple product, it is rare in the market now.

  Three, according to the type and number of sensors.

  1. Sensor types: CMOS and CCD.

  CCD: Charge Coupled Device image sensor, which is made of a high-sensitivity semiconductor material, can convert light into charge, which is converted into digital signal by an analog-to-digital converter chip.

  CMOS: Complementary metal-oxide semiconductor, like CCD, is a semiconductor that can record light changes in digital cameras.

  At the same resolution, CMOS is cheaper than CCD, but the image quality produced by CMOS devices is lower than CCD. So far, most consumer-grade and high-end digital cameras on the market use CCD as sensors; CMOS sensors are used in some cameras as low-end products, but some high-end products also use special CMOS as light sensors, such as several high-end CMOS models of Sony.

  2. Number of sensors: single CCD and 3CCD.

  The number of image sensors is the number of CCD or CMOS sensors of digital cameras. Most digital cameras use a single CCD as their sensors, while some middle and high-end digital cameras use 3CD as their sensors.

  Single CCD means that there is only one CCD in the camera and it is used for photoelectric conversion of brightness signal and color signal. Because a CCD completes the conversion of brightness signal and chroma signal at the same time, the captured image can not meet high requirements in color reproduction.

  3CCD, as its name implies, is a camera using three ccds. We know that if light passes through a special prism, it will be divided into three colors: red, green and blue, and these three colors are the three primary colors used in our TV. Through these three primary colors, all TV signals including brightness signals can be generated. If a CCD is used to receive each color and convert it into an electrical signal, and then an image signal is generated after circuit processing, a 3CCD system can be formed, which can display the primary colors of the image almost intact, and there will be no color error caused by camera deduction.
