Abstract
An image-capturing device of the present invention includes an image-capturing element 10 including a plurality of light-sensing cells arranged on an image-capturing surface; an optical system (14, 20) for forming a first image which is in focus on an image-capturing surface 10a in a first state and forming a second image which is out of focus on the image-capturing surface 10a in a second state; and an image processing section 220 for processing a signal obtained from the image-capturing element 10. The image processing section 220 includes a camera-shake blur removing section for generating a restored image obtained by reducing camera-shake blur from an image obtained by the image-capturing element 10 in the second state.
Claims5
An image-capturing device comprising:
- an image-capturing element including a plurality of light-sensing cells arranged on an image-capturing surface;
- an optical system for forming a first image which is in focus on the image-capturing surface in a first state and forming a second image which is out of focus on the image-capturing surface in a second state;
- a memory for storing a point spread function which defines out-of-focus blur in the second state, and
- an image processing section for processing a signal obtained from the image-capturing element,
- wherein the image-capturing element is configured to capture an image including the out-of-focus blur in the second state, the out-of-focus blur being defined by the point spread function stored in the memory,
- wherein the image processing section is configured to read out from the memory the point spread function which defines the out-of-focus blur and generate a restored image obtained by reducing camera-shake blur from an image obtained by the image-capturing element in the second state, the image processing section using the point spread function which defines the out-of-focus blur to reduce the camera-shake blur from the image.
A non-transitory computer-readable medium storing a program for controlling an operation of an image-capturing device including:
- an image-capturing element including a plurality of light-sensing cells arranged on an image-capturing surface;
- an optical system for forming an image on the image-capturing surface;
- a memory, and an image processing section for processing a signal obtained from the image-capturing element, the program performing the steps of:
- forming a first image which is in focus on the image-capturing surface, by means of the optical system;
- forming a second image which is out of focus on the image-capturing surface, by means of the optical system, the second image including out-of-focus blur which is defined by a point spread function stored in the memory;
- and
- generating a restored image obtained by reducing camera-shake blur from the second image including the out-of-focus blur obtained by the image-capturing element by means of the image processing section using the point spread function which defines the out-of-focus blur to reduce the camera-shake blur from the image.
