An opaque box, this is the camera. The camera is a photographic device that uses light-sensitive film to capture the scene. Its invention has gone through a long time.
China's research on light and image, has a very long history. As early as four hundred years BC, China's "Mojing" book on the detailed record of the straight line of light forward, the reflection of light, as well as plane mirrors, concave mirrors, convex mirrors imaging phenomena. To the Song Dynasty, in the Shen Kuo book "Mengxi Bianan" (1031-1095), also described in detail the "small hole imaging box" principle.
In the 16th century, during the Renaissance, "imaging boxes" for painting appeared in Europe.
On August 19, 1839, the French painter Daguerre announced his invention of the "Daguerreotype", which gave birth to the world's first portable wooden box camera.
In 1841, the photographer Vogtland invented the first camera with an all-metal body. The camera was fitted with the world's first mathematically designed photographic lens with a maximum aperture of 1:3.4.
In 1845, the German Von Maartens invented the world's first camera with an all-metal body. Martens invented the world's first rotary camera that could pan 150°. In 1849, David Brewster invented the stereoscopic camera. In 1849, David Brewster invented the stereoscopic camera and the two-lens stereoscopic viewer, and in 1861, physicist Maxwell invented the world's first color photograph.
In 1866 the German chemist Schott and optician A Gou invented the barium corona optical glass at Zeiss, resulting in a positive light photographic lenses, so that the design and manufacture of photographic lenses, rapid development. 1888 Kodak produced a new type of light-sensitive material - soft, rewindable "film". This was a leap forward in light-sensitive materials. In the same year, Kodak invented the world's first film mounted portable square box camera.
In 1906 the American George? In 1913, the German Oskar Barnack developed the world's first flash. In 1913, German Oskar Barnack developed the world's first 135 camera.
From 1839 to 1924, the first stage of the development of this camera, while there are some novel button-shaped, pistol-shaped camera.
From 1925 to 1938, the second phase of camera development. During this time, the German companies Leitz, Rollei, Zeiss, etc. developed and produced a small size, aluminum alloy body, such as double-lens and single-lens reflex cameras.
At this stage, the performance of the camera gradually improved and perfected, optical viewfinder, rangefinder, *** machine is widely used, mechanical shutter adjustment range is constantly expanding. Camera manufacturing industry began mass production of cameras, camera manufacturers in various countries have imitated the Leica type and Rolleiflex type cameras. Black-and-white photographic film sensitivity, resolution and tolerance continue to improve; color photographic film began to promote the rapid expansion of the photographic team and towards professionalism.
From 1939 onwards, the third stage of camera development. The first half of this stage that is the century before the 1960s, black and white, color film quality has been further improved, the optical industry made a new optical glass containing rare elements, such as lanthanum, titanium, cadmium and other glass. Thus, the aberration of photographic lenses was better corrected, and the lenses developed rapidly in the direction of large apertures and multiple focal lengths. As a result, the emergence of zoom, emblem distance, reflex, wide-angle and other photographic lenses. Lens single-layer coating has been widely promoted. Cameras appeared counter automatic re-zero, reflector automatic reset, semi-automatic and fully automatic contraction aperture and other structures. Camera quality, production began to develop rapidly.
From the early 1960s to the present for the late third stage. During this period, Japan's Konishi Six Photography Company produced the world's first self-supporting focusing camera - Konica C35A 135 camera. Then Japan produced the world's first dual-priority automatic exposure camera - Minolta XDG type 135 single-lens reflex camera. A camera with a variety of exposure functions of the precedent.
During this period, the optical transfer function theory into the field of optical design, the emergence of high image quality, good color reproduction, large aperture, low aberration photographic lens.

Original 1974 Project Summary:
"Create a filmless handheld camera that electronically captures black-and-white still images and records them to a less expensive audio-grade cassette tape drive. The tape deck should be able to be removed from the camera and inserted into a playback device for viewing on a television."
TECHNICAL OPERATION:
The camera takes images from a CCD with 10,000 pixels (arranged in a 100 x 100 array). Each pixel occupies four bits -- a four-digit combination of 0s and 1s that represents each point in the photograph. Once captured, the image is digitized and stored in a memory buffer in the camera. From there, the photographs can be recorded into a more permanent memory that can be removed from the camera for playback. A cassette tape recorder is used for this purpose. From the moment of exposure, it takes about 23 seconds for the camera to write the image to the tape drive.
Question 5: Who invented the digital camera? A Big History of Digital Camera Development
2005.07.28 11:27:08
The camera has been around for almost 200 years, since it was invented by the French in 1839. In these 200 years, the camera has gone from black and white to color, from the pure optical, mechanical architecture evolved into optical, mechanical, electronic trinity, from the traditional silver salt film development to today's digital memory as a recording medium. Laughing at the floating clouds cover the eyes, instantly change the world, the emergence of digital cameras formally marked the camera industry to the digitalization of the new era of leapfrog development, people's image of life has also been completely changed.
Since October 17, 1969, the U.S. Bell Institute's Bauer and Smith announced the invention of the "CCD" (charge-coupled device) since the invention of this light-sensitive components in the further refinement of today's wide range of applications. 4-color CCD, SUPER CCD, and other latest improvements in the version of the The latest improvements such as 4-color CCDs, SUPER CCDs, etc. are constantly emerging, and the number of pixels has already crossed the 10 million pixel mark, while the imaging effect has also been perfected.
After more than a decade of continuous development, the DC industry has been out of its infancy, the appearance of the design is more mature, the operation of the function is becoming more and more powerful, and with the further reduction of the manufacturing cost, the development of these products has shown the development of a *** the development of the seedling.
Overall, the development of the DC industry over the past decade has been adhering to the "higher, faster, stronger, more humane" development vein, and it is under the unremitting efforts of manufacturers, today's digital camera market will become so prosperous and beautiful. People enjoy the convenience of technology at the same time, will not be able to remember the birth of the digital camera in the beginning of the bumpy road, the industry has a significant impact on some of the classic models are still people can not forget.
The Cambrian period - the explosion of life
Many lives suddenly appeared in the Cambrian period, and the whole earth became colorful and full of life overnight. The resolution was still very low, but the involvement of many manufacturers slowly energized the industry.
Sony Mabika (MABIKA) - the world's first electronic camera that does not use photographic film
In November 1973, Sony formally began the "electronic eye" CCD research work, and on the basis of the continuous accumulation of technology, it was released in 1981, with a new camera. On the basis of continuous accumulation of technology, it was launched in 1981 the world's first electronic camera without photographic film - still video "Mavica (MABIKA)". The camera used a 10 mm × 12 mm CCD sheet with a resolution of only 570 × 490 (279,000) pixels, and for the first time, optical signals were replaced by electronic signals.
Immediately after, Panasonic, COPAL, Fuji, Canon, Nikon and other companies have also begun the development of electronic cameras, and in 1984-1986 launched their own prototype electronic cameras, the great explosion of life began.
Sony MYC-A7AF - the first time a digital camera had a purely physical operating method
The second camera in the history of the development of the DC industry is a milestone in the hands of Sony, which can be seen in the company's market position today is by no means a "In 1986 Sony released the MYC-A7AF, which for the first time gave digital cameras a purely physical method of operation, capable of recording still images on a 2-inch disk, and with a pixel resolution that had been extended to 380,000 pixels. Casio VS-101 - The First CMOS Sensor Electronic Camera
In 1987, Casio was the first to market with the VS-101 electronic camera using a CMOS sensor, which was significant for the DC industry, even though the resolution was only able to reach 280,000 pixels.
Today, CMOS and CCD in digital camera sensor orthodoxy has long been settled, CMOS in addition to today's Canon high-end camera is still widely used, other manufacturers have CCD as the leading direction of their products. Undeniably, CMOS has a full range of advantages such as low energy consumption is indeed very attractive, but the disadvantages of low dynamic range can not help people to it "far from it".
Canon RC-760----- the first 600MP model
To get close to the shooting results of traditional cameras, increasing the resolution of CCD pixels is the most fundamental solution, but in the early days of digital cameras, the desire to be more pixelated was ...... >>
