Classification: CPC G  H | IPC G  H

Claim 12:
13. An image processing apparatus, comprising:
at least one memory configured to store instructions; and
at least one processor in communication with the at least one memory and configured to execute the instructions to:
perform correction of a misalignment between a plurality of images captured at exposures different from each other,
detect, as a first detection, an inappropriate area from the plurality of images,
detect, as a second detection, a feature point for the correction by preferentially using an area other than the inappropriate area of the plurality of images, and merge the plurality of images on which the correction has been performed,
wherein the at least one processor executes the instructions to:
detect, in the second detection, the feature point from the area other than the inappropriate area and the inappropriate area, and
in the correction, assign a weight to a feature amount of the feature point detected from the inappropriate area to reduce the feature amount, and use a predetermined number of the feature points in decreasing order of the feature amount of the feature point which has been detected from the area other than the inappropriate area and the feature amount of the feature point which has been detected from the inappropriate area and assigned the weight of the feature point.
