The History of digital photography
Digital photography came into life gradually, step by step.
The US National Aerospace Agency started using digital signals in the 1960s, along with flights to the Moon (for example, to create a map of the lunar surface) — as you know, analog signals can be lost during transmission, and digital data is much less prone to errors.
The first ultra precise image processing was developed during that period, since the National Aerospace Agency used all the power of computer technologies to process and improve space images.
The Cold War, during which a wide variety of spy satellites and secret image processing systems were used, also contributed to the acceleration of the development of digital photography.
The first electronic camera without film was patented by Texas Instruments in 1972.
One of the images of this system, which was contained in the patent, is shown in Fig.
1.3. The main drawback of this system was that the photos could only be viewed on TV.
A similar approach was implemented in Sony's Mavica device, which was announced in August 1981 as the first commercial electronic camera.
the Mavica lamp could already be connected to a color printer.
At the same time, it was not a real digital camera — it was rather a video camera with which you can take and show individual pictures. .
The Mavica camera (Magnetic Video Camera) allowed recording up to fifty images on two inch floppy disks using a CCD sensor with a size of 570-490 pixels, which corresponded to the ISO 200 standard.
It had one shutter speed equal to 1 / 60th of a second, manual aperture adjustment and three interchangeable lenses:a 25 mm wide angle, 50 mm conventional and a 16-65 mm variable focal length lens.
Currently, such a system may seem primitive, but do not forget that Mavica was developed almost 25 years ago!
The appearance of electronic photography in the 1980s was especially exciting for the author.
At that time, as an author of technical literature, I worked at the Eastman Kodak Company (then it was a leader in the field of digital photography) and helped promote such products as the first Kodak Photo CD megapixel system and the Kodak DCS 100 system.
For these systems , the Nikon F3 device was chosen as the base platform, and their price was about 30 thousand dollars.
In fact, these were the first digital cameras that I constantly used (of course, thanks to the Kodak company, since the price was too high).
This digital camera included a 1.3 megapixel sensor (the same sensors are currently used in digital cameras at a price of about $ 100).
The camera allowed you to save images on an external hard disk with a capacity of 200 MB.
The whole set weighed about 25 kg, so only physically strong, and judging by the price, rich photographers could use it.
