Claim 14:
15. An image pickup apparatus, comprising:
an imaging sensor configured to capture a plurality of images at exposures different from each other;
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 the plurality of images,
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 inappropriate area in a case where a number of the feature points detected from the area other than the inappropriate area is less than a predetermined number.
