Abstract:
1. 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.
