ABSTRACT:
The method of detecting corresponding regions between a plurality of pictue images includes respective steps of standardizing the concentration values of respective picture image signals in the operation object regions of a plurality of picture images so that an influence such as the dispersion of the concentration and brightness may be corrected, operating the correlation in the actual fields of the operation object regions and detecting the set of regions in which the operated correlation value is a maximum. The apparatus for realizing this method includes a standardizing device for standardizing the concentration values of respective picture image signals in the operation object regions of a plurality of picture images so that the influence such as the dispersion of the concentration and brightness may be corrected, a correlation operating device for operates the correlations in the actual fields of the operation object regions. A corresponding region detecting device detects the set of regions in which the correlation value operated by the correlation operating device is a maximum.
