Question 1: Who invented the camera? Chapter 1 A brief history of the development of cameras
A light-tight box, this is a camera. A camera is a photographic equipment that uses photosensitive film to capture the scene. Its invention took a long time.
my country’s research on light and images has a very long history. As early as more than 400 BC, my country's "Mo Jing" recorded in detail the linear progression of light, the reflection of light, and the imaging phenomena of plane mirrors, concave mirrors, and convex mirrors. In the Song Dynasty, the principle of the "small hole imaging box" was also described in detail in the book "Mengxi Bi Tan" (1031-1095) written by Shen Kuo.
During the Renaissance in the 16th century, "imaging camera obscura" for painting appeared in Europe.
On August 19, 1839, French painter Daguerre announced his invention of "Daguerreotype", and the world's first portable wooden box camera was born.
In 1841, the optician Vogeland invented the first camera with an all-metal body. The camera is equipped with the world's first photographic lens designed by mathematical calculations with a maximum phase aperture of 1:3.4.
In 1845, the German von Martens invented the world's first rotating machine that could pan 150°. In 1849, David Brewster invented the stereo camera and the two-lens stereo viewer. In 1861, physicist Maxwell invented the world's first color photograph.
In 1866, the German chemist Schott and the optician Agu invented the barium crown optical glass at Zeiss Company, which produced a positive light photographic lens and led to the rapid development of the design and manufacture of photographic lenses. In 1888, the American Kodak Company produced a new type of photosensitive material - soft, rewindable "film." This is a leap forward in photosensitive materials. In the same year, Kodak invented the world's first portable box camera that contained film.
In 1906, American George Silas used flash for the first time. In 1913, German Oscar Barnack developed the world's first 135mm camera.
In the first stage of camera development from 1839 to 1924, some novel button-shaped and pistol-shaped cameras also appeared.
The period from 1925 to 1938 was the second stage of camera development. During this period, German companies such as Leitz, Rollei, and Zeiss developed and produced dual-lens and single-lens reflex cameras with small sizes and aluminum alloy bodies.
At this stage, the performance of the camera was gradually improved and improved, optical viewfinders, rangefinders, cameras, etc. were widely used, and the adjustment range of the mechanical shutter continued to expand. The camera manufacturing industry began to mass-produce cameras, and camera manufacturers in various countries imitated Leica and Rolleiflex cameras. The sensitivity, resolution and latitude of black-and-white photosensitive films continued to improve; color photosensitive films began to be promoted, which led to the rapid expansion and professionalization of the photography team.
From 1939 onwards, it was the third stage of camera development. In the first half of this stage, that is, before the 1960s, the quality of black-and-white and color films was further improved, and the optical industry produced new optical glasses containing rare elements, such as lanthanum, titanium, cadmium and other glasses. This better corrects the aberrations of photographic lenses and enables lenses to rapidly develop in the direction of large apertures and multiple focal lengths. As a result, various photography lenses such as zoom, telephoto, catadioptric, and wide-angle have emerged. Single-layer lens coating has been widely promoted. The camera has structures such as automatic counter zero reset, automatic mirror reset, semi-automatic and fully automatic aperture contraction. The quality and output of cameras began to develop rapidly.
The period from the early 1960s to the present is the latter part of the third stage. During this period, Japan's Konishiroku Photography Company produced the world's first self-supporting focusing camera, the Konica C35A 135 camera. Then Japan produced the world's first dual-priority automatic exposure camera, the Meinon. Up to XDG type 135 single lens reflex camera. This pioneered the use of multiple exposure functions in one camera.
During this period, the optical transfer function theory entered the field of optical design, and photographic lenses with high imaging quality, good color reproduction, large aperture, and low distortion appeared.
At the same time, lenses are developing in series, from fisheye lenses with a focal length of a few millimeters to super telephoto lenses with a focal length of up to 2 meters, and with perspective adjustment, zoom distance, night vision and other photographic lenses. Electronic technology has gradually penetrated into the interior of the camera, and a variety of light metering, high-precision electronic mirror shutters, electronic focal plane shutters, and easy-to-control electronic shutters have appeared one after another. Exposure compensation, storage memory, multi-record function, electric winding film, automatic focus and other functions are available... >>

Original 1974 project summary:
“To create a filmless handheld camera that electronically captures black and white still images and records them to inexpensive audio level cassette tape player. The tape player should be able to be removed from the camera and inserted into a playback device for viewing on a television.
Technical Operation:
The camera passes 10,000 A CCD of pixels (arranged in a 100 x 100 array) captures the image. Each pixel takes up 4 bits -- a four-digit combination of 0 and 1 that represents each point in the photo. Once captured, the image is digitized and stored in a memory buffer in the camera. From here, the photos can be recorded to more permanent storage for playback off the camera.
Cassette tape drives are used for this purpose. From the moment of exposure, the camera takes approximately 23 seconds to write the image to the tape drive.
Question 5: Who is the inventor of the digital camera? A historical record of the development process of the digital camera
2005.07.28 11:27:08
The camera has been around since 1839 Since its invention by the French, it has gone through a development path of nearly 200 years. In these 200 years, cameras have evolved from black and white to color, from purely optical and mechanical structures to the trinity of optics, mechanics, and electronics, and from traditional silver salt film to today's use of digital memory as the recording medium. Smiling at the floating clouds that obscure your eyes, the vast sea turns into mulberry fields in an instant. The emergence of digital cameras officially marks the leapfrog development of the camera industry into a new digital era, and people's imaging life has also been completely changed.
Since Ball and Smith of Bell Research Institute in the United States announced the invention of "CCD" (charge-coupled device) on October 17, 1969, this photosensitive element has been further improved and finally obtained today. widely used. The latest improved versions such as 4-color CCD and SUPER CCD are constantly emerging. The number of pixels has already exceeded 10 million pixels, and the imaging effect has also reached perfection.
After more than ten years of continuous development, the DC industry has long outgrown its infancy. The appearance design has become more mature and the operating functions have become increasingly powerful. With the further reduction of manufacturing costs, the development of this type of products has It shows signs of irresistible development.
Overall, the development history of the DC industry for more than ten years has been adhering to the development context of "higher, faster, stronger, and more humane". It is precisely because of the unremitting efforts of manufacturers , today's digital camera market will become so prosperous and beautiful. While people enjoy the convenience brought by technology, they can't help but think about the bumpy road that digital cameras went through at the beginning of their birth. Some classic models that had a major impact on this industry are still unforgettable.
Cambrian - Explosion of Life
Many lives suddenly appeared in the Cambrian. The entire earth became colorful and full of life overnight. Archaeologists have The reason has not yet been given a clear answer. The 1980s was nothing short of the Cambrian era of the digital camera industry. In less than ten years, digital cameras quickly emerged from their infancy and gradually learned to falter. Although the resolution at that time was still very low, many manufacturers participated. Let this industry slowly become full of vitality.
Sony MABIKA - the world's first electronic camera that does not use photosensitive film
In November 1973, Sony officially began research on the "electronic eye" CCD , based on continuous technology accumulation, it launched the world's first electronic camera without photosensitive film in 1981 - the static video "MABIKA". The camera uses a 10 mm × 12 mm CCD sheet with a resolution of only 570 × 490 (279,000) pixels. It is the first time that optical signals are changed to electronic signal transmission.
Following closely, companies such as Panasonic, COPAL, Fuji, Canon, and Nikon also began the development of electronic cameras, and successively launched their own prototype electronic cameras from 1984 to 1986. That's when the outbreak began.
Sony MYC-A7AF - for the first time, a digital camera has a purely physical operation method
The second camera that is a milestone in the history of DC industry development is also made by Sony. It can be seen that the market position the company has achieved today is by no means a "wasted reputation". In 1986, Sony released the MYC-A7AF, which for the first time gave a digital camera a purely physical operation method, capable of recording still images on a 2-inch disc, and the pixel resolution has been expanded to 380,000 pixels. Casio VS-101 - the first CMOS sensor electronic camera
In 1987, Casio first launched the VS-101 electronic camera using a CMOS sensor on the market, although the resolution could only reach 280,000 pixels. , but this is of great significance to the DC industry.
As of today, the competition between CMOS and CCD in the orthodoxy of digital camera photosensitive devices has long been settled. In addition to being widely used in today's Canon high-end cameras, CMOS has been widely used by other manufacturers. CCD has become the leading direction of its own products. It is undeniable that the advantages of CMOS such as full-frame and low energy consumption are indeed very attractive, but the shortcomings of low dynamic range have to make people stay away from it.
Canon RC-760-----the first 600,000-pixel model
If you want to obtain a shooting effect close to that of a traditional camera, improving the CCD pixel resolution is the most fundamental solution, but in the early days of digital cameras, we wanted to go one step further in terms of pixels... >>
