Abstract
An apparatus includes 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 detect a feature amount from each of a plurality of images different in in-focus position in an optical axis direction, and align the plurality of images by using the feature amount. The at least one processor further executes instructions to detect the feature amount by preferentially using a focusing area of each of the plurality of images.
Claims20
An 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:
- detect a feature amount from each of a plurality of images different in in-focus position in an optical axis direction;
- and
- align the plurality of images by using the feature amount,
- wherein the at least one processor further executes instructions to detect the feature amount by preferentially using a focusing area of each of the plurality of images.
An apparatus comprising:
- a sensor to pick up a plurality of images at different in-focus positions in an optical axis direction;
- 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:
- detect a feature amount from each of the plurality of images;
- and
- align the plurality of images by using the feature amount,
- wherein the at least one processor further executes instructions to detect the feature amount by preferentially using a focusing area of each of the plurality of images.
A method comprising:
- detecting a feature amount from each of a plurality of images different in in-focus position in an optical axis direction;
- and
- aligning the plurality of images by using the feature amount,
- wherein, in the detecting, the feature amount is detected by preferentially using a focusing area of each of the plurality of images.
A non-transitory computer-readable storage medium which stores a program for causing a computer of an apparatus to execute a method, the method comprising:
- detecting a feature amount from each of a plurality of images different in in-focus position in an optical axis direction;
- and
- aligning the plurality of images by using the feature amount,
- wherein, in the detecting, the feature amount is detected by preferentially using a focusing area of each of the plurality of images.
