ABSTRACT:
The method of detecting corresponding regions between primary color picture images comprises respective steps of converting three primary color signals of color picture images to at least two signals based on these three primary color signals, calculating the variance of the mutual concentration distribution in the operation object regions of the three primary color picture images from these converted signals and detecting the set of regions in which the calculated variance value is minimum. The apparatus for realizing the above mentioned method comprises a converting device for converting three primary color picture signals of color picture images to at least two signals based on these three primary color signals, a variance calculating device for calculating the variance of the mutual concentration distribution in the operation object regions of the three primary color picture images from the signals converted by this converting device and a corresponding region detecting device for detecting the set of regions in which the variance value calculated by this variance calculating device is minimum.
