15. A blur correction apparatus, comprising:
-
an image acquirer adapted to acquire a first image by shooting using an image sensor and acquire a plurality of short-exposure images by a plurality of times of shooting each performed with an exposure time shorter than an exposure time of the first image; a second image generator adapted to generate from the plurality of short-exposure images one image as a second image; and a corrector adapted to correct blur contained in the first image based on the first and second images. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. A method of correcting blur, comprising:
-
an image acquisition step of acquiring a first image by shooting using an image sensor and acquiring a plurality of short-exposure images by a plurality of times of shooting each performed with an exposure time shorter than an exposure time of the first image; a second image generation step of generating from the plurality of short-exposure images one image as a second image; and a correction step of correcting the blur contained in the first image based on the first and second images.
