Abstract:
1. A color correction apparatus for images captured by a plurality of cameras ordered 1, 2, . . . , n, comprising: first means for storing a correction order defining a plurality of camera pairs and an order of the camera pairs, each camera pair defining a reference camera and a target camera; and second means for correcting 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 for replacing the target image by a corrected target image, for each camera pair in accordance with the order of the camera pairs, wherein each camera is treated as a target camera at least one time, when camera n is corrected, the correction continues reversely, and the reference camera in each camera pair is treated as the target camera in a previous camera pair except for a first camera pair of the correction order, the second means comprises: lookup table generating means for generating the lookup table by setting a distribution value for each coordinate on an x-y plane based on the total distribution, and by selecting one coordinate for each x value, wherein an x value of the selected coordinate indicates a pixel value before correction, and a y value of the selected coordinate indicates a pixel value after correction.
