SYSTEM FOR CONTROLLING IMAGE OF SATELLITE

摘要

PURPOSE: A satellite system for controlling a video is provided to prevent an error which changes a tone of an output image of a satellite body according to the temperature. CONSTITUTION: A detected temperature of an optical detector(232) is over the set reference temperature. By correcting the tone of a digital image signal, a temperature compensator(222) outputs a first digital compensation signal. Through a compensation table, a physical deviation between a plurality of pixels is corrected. A non-uniform compensator(223) revises a first digital revision signal as a second digital revision signal.
