1. An image taking apparatus comprising:
- (a) an image pickup device which captures at least three images sequentially;
(b) a detection unit which detects shift amounts between a first image among the at least three images and each of the other images;
(c) a coordinate conversion unit which performs coordinate conversion so that the other images overlap the first image based on a detection result in the detecting unit;
(d) a synthesis unit which synthesizes the first image and the other images as one synthesis image by performing the coordinate conversion in the coordinate conversion unit; and
(e) an adjusting unit which darkens brightness in a first region of each of the other images, the first region corresponding to a region irradiated with light in the first image,wherein the first image among the at least three images is captured by using an illumination unit, and the other images are captured without using the illumination unit and are at least two captured images.

Abstract
An image processing apparatus, which obtains a synthesized image whose exposure is corrected by synthesizing a first image and a second image, is disclosed. The image processing apparatus comprises a detection section which detects an amount of displacement of the second image with respect to the first image which is a reference image, a coordinate conversion section which performs coordinate conversion to the second image so as to conform to the first image, and a synthesis section which synthesizes the second image having been subjected to the coordinate conversion with the first image.

9. A control method of an image taking apparatus comprising an image pickup device capturing an image, comprising the steps of:
-
(a) capturing at least three images sequentially by the image pickup device; (b) detecting shift amounts between a first image among the at least three images and each of the other images; (c) performing coordinate conversion so that the other images overlap the first image based on a detection result in the detecting unit; (d) synthesizing the first image and the other images as one synthesis image by the coordinate conversion in the performing step; and (e) darkening brightness in a first region of each of the other images, the first region corresponding to a region irradiated with light in the first image, wherein the first image among the at least three images is captured by using an illumination unit and the other images are captured without using the illumination unit, the other image being at least two captured images.
