SHADING COMPENSATION CIRCUIT AND METHOD

摘要

an A/D converter(12) for converting an analog image signal outputted from an image sensor(10) into digital data; a shading memory(14) for storing the digital data in the address of each pixel and storing shading data corresponding to each pixel location; a controller(16) for detecting the most bright image data from the image data stored in the shading memory(14) and storing the shading data in the shading memory(14); and the image sensor(10) for scanning and outputting image data.
