Image capturing apparatus and camera shake correction method, and computer-readable medium
First Claim
1. An image capturing apparatus comprising:
- an image capturing unit configured to capture an image of an object;
an image capture controller configured to;
(i) cause the image capturing unit to capture a plurality of first color component images of the object by multi-shot exposure within a given exposure time at the time of image shooting, wherein each of the first color component images has a first color component; and
(ii) causing the image capturing unit to capture a second color component image of the object and a third color component image of the object by a one-shot exposure within the given exposure time, wherein the second color component image and the third color component image have color components different from the first color component, respectively;
a displacement information acquiring unit configured to;
(i) set one of the first color component images as a reference image; and
(ii) acquire displacement information of the object in the first color component images other than the reference image, with respect to the object in the reference image;
an image adding unit configured to align and add the first color component images based on the displacement information so as to generate an added image;
a calculator configured to calculate a first point spread function (PSF) based on the displacement information;
a first correcting unit configured to correct the second and third color component images using the first point spread function; and
a combining unit configured to combine the added image with the corrected second and third color component images.

Abstract
An image capturing apparatus includes: an image capturing unit capturing an image of an object; an image capture controller that causes the image capturing unit to capture first color component images having a first color component by multi-shot exposure, and causes the image capturing unit to capture second and third color component images, a displacement information acquiring unit that acquires displacement information; an image adding unit that aligns and adds the first color component images based on the displacement information to generate an added image; a calculator that calculates a first point spread function based on the displacement information; a first correcting unit that corrects the second and third color component images using the first point spread function; and a combining unit that combines the added image with the corrected second and third color component images.

8. A computer-readable medium storing a program for causing the computer to perform operations comprising:
-
(a) capturing an image of an object; (b) capturing a plurality of first color component images of the object by multi-shot exposure within a given exposure time at the time of image shooting, wherein each of the first color component images has a first color component; (c) capturing a second color component image of the object and a third color component image of the object by a one-shot exposure within the given exposure time, wherein the second and third color component images have color components different from the first color component, respectively; (d) setting one of the first color component images as a reference image; (e) acquiring displacement information of the object in the first color component images excluding the reference image, with respect to the object in the reference image; (f) aligning and adding the first color component images based on the displacement information so as to generate an added image; (g) calculating a first point spread function (PSF) based on the displacement information; (h) correcting the second and third color component images using the first point spread function; and (i) combining the added image with the corrected second and third color component images.
