Method for brightness equalization of various images

摘要

The present invention provides a method for brightness equalization of a plurality of images to equalize brightness when composing, into a single image, a plurality of images acquired from a plurality of cameras.

主权项

1. A method for brightness equalization of a plurality of images, the method comprising:
receiving at least two input images; composing the at least two input images into a single composite image; setting a correction area corresponding to each input image in the composite image, and calculating a brightness histogram of each correction area; calculating a representative value of at least one modal in the brightness histogram, and grouping a modal of each correction area based on the representative value; calculating a correction target value of each group based on a representative value of modals grouped into each group; calculating a corrected value by subtracting the representative value of modals of each group of each correction area from the correction target value of each group; and correcting brightness by adding the corrected value to a pixel value of each group of each correction area.
