Color processing apparatus and method

Abstract

The invention relates to a color processing unit, which comprises a delay unit and a processing unit, wherein the delay unit is used for receiving photosensitive data output by a photosensitive element for delaying, the delay unit is provided with a plurality of output ends for respectively outputting a plurality of photosensitive data after the delaying, the processing unit is provided with a plurality of input ends, wherein a part or all of the input ends are connected with a plurality of the output ends of the delay unit, the processing unit is used for simultaneously receiving the photosensitive data output by a plurality of the output ends of the delay unit and calculating the color data of various colors in a plurality of the photosensitive data. The color processing unit simultaneously outputs a plurality of the photosensitive data after delaying the photosensitive data output by the photosensitive element one by one through the delay unit with a plurality of the output ends, which enables the subsequence to simultaneously obtain a plurality of the photoactive data, and greatly speeds up the speed of obtaining data compared with reading the photoactive data one by one by the software method, thereby speeding up the color separation of a plurality of the photoactive data and improving the imaging speed. The invention further provides a color processing method.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a color processing device and method. Background technique [0002] State-of-the-art CMOS and CCD image sensors can only record grayscale values, that is, a series of tones from pure white to pure black. They can only obtain brightness information by the number of captured photons. Therefore, the basic principle of a color camera to obtain a color image is to install a color filter lens on the photosensitive element, and then synthesize a color image in various ways. At present, the working principle of the color photosensitive elements commonly used in the market is as follows: R / G / B filters are placed on each pixel unit, and the R / G / B filters can only capture one of the three colors. Then, the colors of the three filters are mixed by an algorithm to obtain color image data (such as figure 1 shown). [0003] see figure 2 with image 3 , figure 2 It is a photosensitive mat...
