PROBLEM TO BE SOLVED: To perform more proper exposure correction or white balance correction by accomplishing photometry or colorimetry weighted suitably for a shape or a location of a main object such as a human figure. SOLUTION: The shape of a main object such as a human figure is extracted from original image data, an area of the main object meeting the shape of the main object is defined as an area for photometry/colorimetry, a plurality of areas including the area of the main object are determined as weighted areas, and a weighting coefficient is allocated for each of the weighted areas. On the other hand, an entire picture is divided into a plurality of divided areas, a measurement of divided photometry and/or divided colorimetry is calculated for each of the divided areas, and a weighting coefficient is determined for a measurement calculated for each divided area. Based on the measurement calculated for each divided area and the weighting coefficient determined for each weighted area to which the divided area of each measurement belongs, exposure correction and/or white balance correction is then performed.
