Programming: It is known that the true color photos taken by digital cameras are 20 million pixels, so writing a program to input the camera memory card can store photos at most.

There are also lenses and image processing engines that affect the imaging of digital cameras, which are also digital cameras with 1000W pixels. If you choose the same resolution, the effect and size are different because of different brands.

When choosing a removable digital storage medium, Cezanne hoped that its storage capacity would be similar to that of 35mm film, so he finally adopted a universal cassette recording tape, which can basically store 30 photos equivalent to a film. "At that time, many technologies were very new. The circuit board of this prototype can be tuned while shooting. " Cezanne seems to have returned to the laboratory.

Working principle:

It integrates the conversion, storage and transmission of image information, and has the characteristics of digital access, interactive processing with computer and real-time shooting. Light enters the camera through a lens or lens group, and is converted into a digital signal through an imaging element of a digital camera, and the digital signal is stored in a storage device through an image operation chip.

The imaging element of digital camera is CCD or CMOS, which is characterized in that when light passes through it, it can be converted into electrical signals according to different light. Digital cameras first appeared in America. More than 20 years ago, the United States used it to transmit photos to the ground via satellite. Later, digital photography was converted to civilian use, and its application scope continued to expand.
