Image capturing apparatus, image processing apparatus, image processing method, and image processing program

摘要

This image capture device is configured to generate a restored image by reducing a motion blur that has been induced by a camera shake during shooting. The device includes: an image sensor 10; an optical system 20; and an image processing section 220 which processes an image signal that has been obtained by the image sensor 10. The image processing section 220 includes: a blur kernel determining section which determines a blur kernel that defines the camera-shake-induced motion blur of the image captured; and an image restoration section which generates the restored image. The blur kernel determining section changes the size of the blur kernel by reference to information that affects the degree of the blur of the image such as the zoom power of the optical system 20.

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 sensor; an optical system which produces an image on an imaging area of the image sensor; and an image processing section which processes a signal that has been obtained by the image sensor, 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 image that has been captured by the image sensor, the blur kernel being a coefficient matrix representing a point spread function; and an image restoration section which generates the restored image by reducing the camera-shake-induced motion blur from the image using the blur kernel that has been determined, and wherein the blur kernel determining section sets the size of the blur kernel by reference to information that affects the degree of the blur of the image, the size of the blur kernel being the number of elements of the coefficient matrix, and wherein the blur kernel determining section changes the size of the blur kernel according to an exposure time.
