Abstract
The present invention relates to color correction of video signals from a plurality of cameras. The apparatus has a correction order that defines a plurality of camera pairs and an order of the camera pairs, where each camera pair specifies a reference camera and a target camera. In the correction order, each camera is treated as a target camera at least one time, and the reference camera is treated as the target camera in a previous camera pair except for the first camera pair. The apparatus corrects a value of each pixel in a target image captured by the target camera based on a reference image captured by the reference camera, and replaces the target image by the corrected target image, for each camera pair in accordance with the order of the camera pairs.
