1. An image capture device which is configured to generate a restored image by reducing a motion blur that has been induced by a camera shake during shooting, the device comprising: an image capturing section which captures a first image and a second image, which is obtained in a shorter exposure time than the first image, in a single shooting session; and an image processing section which performs restoration processing on the first and second images that have been captured by the image capturing section, and wherein the image processing section includes: a blur kernel determining section which determines a blur kernel that defines the camera-shake-induced motion blur of the first image that has been captured by the image capturing section; and an image restoration section which generates the restored image by using the blur kernel that has been determined, and wherein the blur kernel determining section changes the size of the blur kernel according to the exposure time in which the first image is captured.
