CAMERA MODULE FOR PROCESSING LENS SHADING AND AN OPERATING METHOD THEREOF, CAPABLE OF REALIZING OPTIMUM PICTURE QUALITY EVEN THOUGH THE COLOR TEMPERATURE OF A SUBJECT IS HIGH OR LOW

摘要

PURPOSE: A camera module for processing lens shading and an operating method thereof are provided to differently set values of a lens shading register according to color temperature.;CONSTITUTION: An image sensor(20) changes an optical image to an image signal. A lens shading register(30) sets a register value for lens shading. An image signal processor(50) presumes the color temperature of the image signal. The image signal processor extracts the value of the lens shading register matched with the presumed color temperature.;COPYRIGHT KIPO 2010
