METHOD FOR COMPENSATING DEGRADATION OF DETECTOR PERFORMANCE USING HISTOGRAM SPECIFICATION

摘要

According to the present invention, an image processing means using a histogram specification method comprises the steps of: calculating a histogram of an image outputted from a plurality of image detection units; performing histogram equalization on the image; selecting one image detection unit from among the plurality of image detection units; and performing inverse histogram equalization on the image, in which histogram equalization has been performed, using characteristics of the image acquired by the selected image detection unit.
