Document Type and Number:
Japanese Patent JP6590894
Kind Code:
B2
Abstract:
To enhance the accuracy of a conversion coefficient detected from a plurality of images captured while finely moving an in-focus position, an image processing apparatus includes a detection unit configured to detect feature points from a plurality of images having different in-focus positions, and a combining unit configured to calculate a conversion coefficient for alignment using the feature points and perform combining processing based on the conversion coefficient. The combining unit calculates a conversion coefficient of a second image in the plurality of images with respect to a first image in the plurality of images based on a conversion coefficient calculated using the feature points detected from the first image and a third image in the plurality of images.
