APPARATUS AND METHOD FOR COMPENSATING BRIGHTNESS OF IMAGE

摘要

An apparatus and a method for compensating the brightness of an image are provided to reduce time and an operation amount necessary for compensating the brightness of the image as it is unnecessary to perform repeated feedback using at least one of brightness information and gain information. An image acquisition unit(110) acquires the image of a predetermined subject, and an initial brightness detection unit(120) detects the initial brightness of the image acquired by the image acquisition unit in initial exposure. An image compensation unit(160) compensates the brightness of the acquired image so as for the detected initial brightness to be target brightness. An external light detection unit(140) detects the brightness of an external light. A brightness information storage unit(130) stores brightness information about the brightness of the acquired image according to an exposure time. An exposure adjustment unit(150) adjusts the exposure time.
