Claim One:
1. An image capture apparatus for capturing an image of a subject, comprising: a correction unit which corrects distortion of a shape of a subject in a plurality of captured images obtained by shooting the subject from different directions, to obtain distortion-corrected images; an image synthesis unit which performs a predetermined calculation for each pixel in the plurality of distortion-corrected images obtained by the correction unit in order to reduce a change in a pixel value which is caused by glare from a light, and synthesizes a corrected image from the plurality of distortion-corrected images; wherein the image synthesis unit: obtains a parameter indicating an intensity of a light when the subject is shot for each pixel from a first image and a second image which are to be synthesized, and obtains a difference obtained by subtracting a value of the parameter of the first image from a value of the parameter of the second image for each pixel; selects a pixel value of the second image to be a pixel value of a synthesized image, in a first case in which the obtained difference is smaller than a preset first threshold; selects a pixel value of the first image to be a pixel value of a synthesized image, in a second case in which the first image is already a synthesized image having been synthesized before, and the obtained difference is larger than a preset second threshold; and selects a value obtained by averaging the pixel value of the first image and the pixel value of the second image based on a number of times image synthesis has been performed, to be a pixel value of a synthesized image, in cases other than the first and second cases, thereby to synthesize the corrected image from the plurality of distortion-corrected images.
