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.

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.

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.

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.

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.

How to adjust the lighting in children’s room? Don’t leave out these details

 one

Don’t choose lamps that are easy for children to touch the light bulb.

  Text/Figure Yangcheng Evening News reporter Liang Dongxian Intern Zhao Xiaoling (except signature)

  In many people’s conventional cognition, it is not good for children’s rooms to be too bright or too dark, especially for study. However, there are some new ideas that may subvert the traditional concepts you used to know.

  Author of Building a Growing Children’s Room from scratch — — Xu Xiao, a cross-border designer, said that even on cloudy days, the outdoor illumination is 10,000 lumens (lumens are the illumination unit), and people do not feel any discomfort when reading outdoors on cloudy days; However, indoor lighting rarely exceeds the same illuminance. Therefore, as long as the lighting is not direct to the eyes, there is basically no problem of over-lighting in children’s rooms, and it will not cause vision problems. Is this view correct?

  School is about to start. What should you pay attention to when you are ready to rearrange the lighting in the children’s room?

  Children’s myopia,

  The main reason is not the light!

  Is Xu Xiao’s point of view correct? Yangcheng Evening News reporter interviewed Sun Keqing, deputy chief physician of the Department of Ophthalmology, the First Affiliated Hospital of Guangzhou Medical University. She said that Xu Xiao’s views are basically correct. Because as long as it is not direct vision or specular reflection, indoor routine reading lighting can rarely reach the level of damaging vision, so it is no harm to light it up.

  If myopia is not related to too bright light, what is the main cause of myopia among teenagers?

  Sun Ke Qing said that the main reasons are incorrect writing posture, or too long use of eyes. If you want to reduce the possibility of children’s myopia, it will be very beneficial to ensure a certain amount of outdoor exercise time every day.

  Of course, Sun Ke Qing said that improper lighting design can also cause children’s vision problems. For example, the lamp does not have a suitable lampshade or the height design of the lamp is unreasonable, which makes the light directly or reflect to the eyes. In addition, if it is a baby’s room, because the baby’s eyes are not fully mature, so you can’t use too strong and dazzling lights to avoid damaging their eyes. At this time, the lighting design should be as soft as possible.

  The light should be bright and soft.

  In fact, children’s rooms generally have the functions of studying, playing, resting and storing things at the same time. The overall indoor illumination should be higher than that of adult rooms. At the same time, the light should be soft and avoid glare. In addition, in different areas such as the study area, it is necessary to have corresponding local lighting to facilitate children to read books, do homework and find books.

  The overall lighting of children’s rooms can use chandeliers and ceiling lamps to create bright and fantastic lighting effects for the space, while the local lighting can meet different lighting needs with wall lamps, table lamps and spotlights. The selected lamps should give children a relaxed and interesting light sense in shape and color, so as to expand their imagination and stimulate their interest in learning.

  Sun Keqing suggested that the lamps in children’s study area can choose eye protection lamps. Good eye protection lamp is not easy to strobe, and its brightness and brightness uniformity are ideal, which can reduce eye fatigue and help children protect their eyesight.

  These security risks cannot be ignored.

  In addition, when installing lamps, we should also pay full attention to safety issues. Children are lively and active by nature, full of strong curiosity about things, especially young children, but they lack the necessary awareness of self-protection. Therefore, if the lamps are installed in children’s rooms, especially in infants’ rooms, care should be taken not to expose the power cord as much as possible, so as to avoid the unreasonable children playing with the wires as toys, thus causing the danger of electric shock.

  In addition, if the child is still very young, don’t choose lamps that are easy for the child to touch the light bulb, because many lamps will also heat up when they shine, and adults think that the negligible temperature is likely to burn the child’s tender skin. Therefore, when arranging the nursery, it is best to choose a lamp with a closed lampshade, or add a protective cover to the light bulb. In addition, movable lamps such as floor lamps and desk lamps should also be avoided in preschool children’s rooms to minimize the risk of electric shock.

International Hot Review: The whole world is dancing this dance. I didn’t expect this wave of culture to go out of the circle!

This article was transferred from [China News Network];
Zhongxin. com, December 18 (Zhang Naiyue) "Hands are shaking, feet are shaking". Recently, a dance called "Subject Three" has been constantly swiping the screen network, and even set off a craze around the world.
Even the Royal Russian Ballet, which is touring in China, "do as the Romans do". After the performance, it suddenly danced the popular online dance "Subject III", which won applause and laughter, and caused a heated discussion on the Internet.
"Swan Lake" meets "Subject 3"
The full name of "subject three" is "subject three in Guangxi", and its origin has been difficult to verify. Many people think that it comes from the anecdotal saying that "every Guangxi has to go through three exams in life: singing folk songs, talking about rice noodles and dancing".
Some netizens introduced on Russian social media that the popular "Ballet Edition Subject III" came from a performance of the Royal Russian Ballet in Shenyang, China recently. After the performance of "Swan Lake", the ballerinas danced "Subject III". Many dancers dressed in ballet costumes danced in unison with the rhythm of modern electronic music, and some people could not help smiling.

This video also caused a sharing craze on social media platforms such as Facebook, X (original Twitter) and TikTok.
Some netizens said, "The adaptation is very interesting", "Ballet can’t escape the third subject" and "The ubiquitous third subject". Others left a message saying that "I didn’t expect this wave of culture to go out of the circle".
From "going out of the circle" to "going out to sea"
Not only ballet, "Subject III" also collided with Latin dance. At the 2023 World Sports Dance Grand Prix held in Shanghai in early December, many dancers, including the world champion of Latin dance, showed the "Subject III" combined with Latin dance steps, and the movements were full of power.
At present, "Subject 3" has become a hot challenge project of the global short video platform. Netizens from all over the world have left messages on social media, or shared their videos of "Subject 3".
Some people think that the action of "subject three" is cute.
Others worry about the fragile ankles behind the dancers’ silky steps.
"Subject 3" has sprung up in South Korea, and some people performed at the school graduation party, which attracted cheers from the audience. The entry of "subject three Korea" once rushed to the hot search. Some people said it was "wonderful" and thought it was "culture out of the circle", while others were curious. "Why is the whole world jumping?"
There are also bloggers who record teaching videos and teach "subject three" by hand.
Image source: screenshot of social platform
Some Korean netizens left a message under the video of a Jianghu dance teaching, "I really want to learn this."
More Russian bloggers dressed in cheongsam in Moscow’s Red Square challenged "Subject 3" for three times below zero. Some people are surprised that "subject three is popular all over the world?" Some people found that people in the video jumped up with them, and others reminded bloggers to keep warm.
Image source: Little Red Book blogger "Shao Dong in Russia" video screenshot
In addition, netizens from Britain, Ukraine, the Philippines, Spain and other countries showed off their dancing and attracted numerous praises.
Smile, dance and resonate.
"Subject III" can dance both solo and in groups: people twist their waists, swing their hips and wave their hands, and with their ankles half twisted, they are extremely silky in one go, which is called "in line with the mental state of contemporary people" and "the square dance of young people". Even if you watch it, you can have fun and relax from the video.
Image source: Tik Tok blogger "Love Beauty" video screenshot
Overseas, "Subject III" first spread among China students, and then "spread" to overseas teenagers. Many young people with foreign faces shouted, "The Russian area is divided", "The English area is not big, creating myths" and started "competition", which added heat to the "subject three".
Music and dance are ways of communication that can transcend nations and languages. "Subject III" spread quickly because of its easy-to-understand and relatively easy-to-remember dance and "brainwashing" music, which easily mobilized the senses and was easily imitated.
However, the success of "subject three" in becoming a cultural phenomenon "going out of the circle" or even "going out to sea" is inseparable from the feeling of relaxation and freedom it brings to people, which is a simple happiness that netizens from all over the world can experience. Faced with the pressure of reality, modern people can show their personality, gain resonance and vent their emotions by playing with stalks, and they can find happiness from it no matter where they come from.
The collision between ballet, Latin dance and the popular internet stem "Subject III" is the communication between tradition and modernity, and also the communication between different cultures. Between a gesture and a slide, the audience and dancers will smile, and different nationalities will know each other better.

Wonderful Classroom | Shanghai Pudong Vanke Kindergarten makeU Baby Robot Programming officially started.

On October 27th, 2022, makeU Kindergarten, a private Vanke kindergarten in Pudong New Area, Shanghai, officially started its class. It used the mode of "building blocks+physical programming" to bring unprecedented artificial intelligence experience to children.

This is the first class of "Building Block Robot+Physical Programming" in kindergarten. Children can’t wait to open the makeU robot suit in their hands. Under the guidance of the teacher, they build the ideal robot shape step by step, and gradually form the ability of space construction in hands-on practice.

Large-sized blocks are more suitable for teaching in early childhood. In simple block insertion and disassembly, children gradually master the structural knowledge such as interlocking structure and balance structure.

Through the teacher’s lively and interesting explanation, the children have a preliminary understanding of the building block programming robots in their hands: controllers, motors, ultrasonic sensors … In the practice of one interesting project, robots gradually become friends of children, and science and technology are no longer unfamiliar concepts and symbols, so that children can grow up with artificial intelligence from an early age.

When the children are proficient in programming methods, they start a wonderful programming journey with makeU reading pen in their hands.

"Forward, backward, ultrasonic lights on!" Under a series of programming instructions, the robot in the child’s hand "came alive" instantly, and accurately executed the action according to the logical instructions spliced by the child. In this way, the seeds of science and technology are buried in children’s hearts, expecting children to continue watering them with scientific enthusiasm.

The application of artificial intelligence in preschool education is the development trend of future school education reform. Whale robot innovates the form of preschool education activities, adopts the trinity teaching of "play-learn-practice", combines classroom knowledge absorption with challenging activities, fully mobilizes children’s interest, enhances children’s self-confidence, and cultivates children’s ability to solve problems and resist setbacks.

The robot provides products, teaching, training and competition for children’s artificial intelligence education, and the four-in-one comprehensive support is convenient for the kindergarten to carry out teaching activities.

Part II: Tips

Type of skills can be roughly divided into four types, text skills, lend white skills, graphic skills, color skills.

01 / font skill

Select the most comfortable font size

The font size of the font size has a relatively regular magnification, that is, 0.5 times relationship growth

Select the level of the font

Multiple family text information block processing relationship, visual experience between different locations, text blocks, pay attention to the comfort of the font spacing and the line spacing.

Select the level of the font

Different dimensional texts on the above visual experience.

Font selection

Understand the character of the font, avoid using the default font to avoid using the transition to use and ugly fonts, pay attention to avoid simultaneous use of both fonts and two or more different colors.

Font selection

Pay attention to the readability of the text, do not leave a lonely word, use small uppercase letters and carefully use the text of the text.

02 / Dossy Tips

What is a white?

Even if we call it "white", it does not mean that the actual space must be white.

As long as you don’t repeat any graphics or elements on the page. It originates from traditional art, which is originally the difference in the shape of the user more accurately.

Dossy is a space between each element and the surrounding space. When the designer talks about the white: they are actually negative space.

The word "negative space" originated in conflict, blank spaces can be filled with any color. The actual white and "留 白" "negative space" did not really associate, "darker" and "negative space" can be used interchangeably.

Do you want to leave?

Dossy is the basic element of the design, leaving a white simply is a premeditated guidance reader to capture the information necessary to express the information.

And improve the visual feeling of reading.

In the layout of the work set, there is enough space to reserve enough space, do not let information are too stacked, accounting for full space. Too many information will directly lead to a decrease in the interest of the examiner, and a slightly sparse version of the typography will make reading more comfortable.

Picture with text

Dossy is a simple art. You don’t have to pursue information on the page and drawings. Appropriate leaves give people a reading rest, and you can also cause unlimited imagination.

03 / graphic skills

A / Emphasize graphic comparison, increasing visual readability

Using contrast color and complementary color, enhance the readability of information, select the main color according to the subject, and use another color to match the decoration, produce visual tension, attract reading readers.

A

B

B / Weak background

Weak background, fuzzy color reduces the level of reading order,

Highlight design destination visuality and information readability,

The weakening of the background, the convexity of the text will make information reading more visual impact.

A

B

Weak background, emphasizing information.

C / segmentation geometry screen

Add a rectangular boundary box other than the text or set a color block under text, forming a product label, and the relationship is generated by the background and label, allowing the user to focus on the geometry.

Through the segmentation of the geometric frame, the reader’s vision center is focused on the information points within the frame.

D / gold segmentation skills

Gold segmentation: The ratio of the shorter portion of the line segment is equal to the longer portion and the overall length ratio, and its ratio is about 0.618.

A

B

Layout: Set the size into a gold segmentation ratio.

Rebum: Use the gold segmentation ratio to control the white space.

Content: Try to utilize the proportion of gold.

04 / color skills

A / contrast color

Two colors of the 12 color phase rings are 120 ° color. The matching method of the color color can generally use the color of the picture very jumped. It is now much more than sports products.

B / same color

Then there are two colors of the 12 color phase rings in the color of 30 °. Use the similar color on the product to enhance the overall feeling of the picture.

C / complementary color

The distance between the two colors in the 12-color ring is 180 ° color. The complementary color is exaggerated, and the visual impact is very strong.

D / neighboring color

The distance between the two colors in the 12 color phase ring is 60 ° color. The neighboring color is a relaxed feeling.

Co-like – then two colors of the two colors in the 12-color rings in the color of 30 °. Use the similar color on the product to enhance the overall feeling of the picture.
