Abstract:
1. A method for image processing for obtaining a combined image data by combining a plurality of image data obtained by a plurality of times of image capturing, the method comprising: detecting brightness distribution for each of the plurality of image data and the combined image data; calculating a characteristic amount of each detected brightness distribution; calculating a target value of the characteristic amount of the brightness distribution of the combined image data from the characteristic amount, wherein the target value is the characteristic amount of the brightness distribution of the image data which has a highest contrast among the plurality of image data, and includes both a target value of the characteristic amount of a dark side of the brightness distribution and a target value of the characteristic amount of a bright side of the brightness distribution; and acquiring a correction amount for a tone correction executed to the combined image data based on the obtained target value.
