1. How CCD works
Compared with traditional film, CCD is closer to the way the human eye works on vision. It's just that the retina of the human eye is composed of rod cells responsible for light intensity sensing and color sensing cone cells, which forms a visual response by cooperating with the division of labor. After 35 years of development, the general shape and operation of CCD have been fixed. The composition of the CCD is mainly composed of a mosaic-like grid, condenser lenses, and a matrix of electronic circuits under the bottom. The companies currently capable of producing CCD are: SONY, Philps, Kodak, Matsushita, Fuji, SANYO and Sharp, most of which are Japanese manufacturers.
