[0064] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present invention.
[0065] In order to better understand the content of the present invention, it is necessary to understand the basic knowledge of the colors used in the present invention. The generation of the color involved in the present invention is divided into two categories: transmission and reflection. Transmission is usually used for display and CCD imaging. absorbed. In a typical RGB color system, each pixel is usually composed of at least one pixel of red R, green G, and blue B in the pre-transmission filter of the electrically coupled device (CCD), because only the same color as the filter , is perceived by the CCD element, and the perceived signal is divided into several levels according to the int...
