ABSTRACT:
In order to enable preferable determination of correction parameter values of image information including a plurality of object areas, each of the correction parameter values for correcting the image information is calculated for each of a plurality of object areas included in input image information on the basis of a feature amount and an importance degree of each area, and a correction parameter value for correcting the input image information is determined by synthesizing the respective calculated correction parameter values, whereby a position and an areal size or brightness of each object area can be reflected in the correction parameter value, and one correction parameter value for the whole input image can be determined.
