Introduction of camera imaging principle

1, the charge coupled device (CCD) receives the image transmitted by the optical lens, converts it into a digital signal through the analog-to-digital converter, and stores it in the memory. The optical lens of a digital camera, like a traditional camera, focuses the image on a photosensitive device, that is, a charge-coupled device (CCD). CCD replaces the position of photosensitive film in traditional cameras, and its function is to convert optical signals into electrical signals, which is the same as that of television photography. CCD is a semiconductor device and the core of digital camera, and the number of units in it determines the imaging of digital camera.

2. A camera is a device that uses the principle of optical imaging to form an image and records the image with a negative. This is an optical instrument used for photography. In modern social life, there are many devices that can record images, all of which have the characteristics of cameras, such as medical imaging equipment and astronomical observation equipment.

3. After the light reflected by the shot scene is focused by the camera lens (shooting mirror) and the shutter for controlling exposure, the shot scene forms a latent image on the photosensitive material in the camera box, and forms a permanent image after being developed and fixed. This technology is called photography, which is divided into general photography and professional photography.
