A detection unit detects, on the basis of the contour signal, a representative contour direction for each of a plurality of division regions of the image, where the detection unit detects a specific direction as the representative contour direction when the direction of the entire contour portion included in the division regions is biased in the specific direction by at least a specific degree. A determination unit determines a type of the subject on the basis of at least one of a direction-based frequency distribution of the detected representative contour directions, a number of representative contour directions detected, etc. A correction unit configured to correct the image data according to a correction method corresponding to the type of the subject.
