Abstract

The present invention provides an image pick-up apparatus and iamge recoery method. The image pick-up apparatus includes an optical system which forms a subject image. An image pick-up unit obtains image data from the subject image formed by the optical system. A vibration detecting unit detects a vibration of the image pick-up apparatus. In an image deterioration information storage unit, information of image deterioration generated by the optical system is stored. An image deterioration correcting unit corrects the image deterioration generated by the optical system with respect to the image data output from the image pick-up unit in accordance with the image deterioration information stored in the image deterioration information storage unit. A vibration restoring unit restores the image deteriorated by the vibration with respect to the image data output from the image deterioration correcting unit in accordance with the vibration detecting signal of the time series.

Description

technical field

[0001] The present invention relates to an imaging device and an image restoration method in which vibration is detected to restore a blurred image to a blur-free image. Background technique

[0002] In an imaging device such as a digital camera, a video camera, etc., an image degraded by vibration at the time of imaging is corrected to restore an image close to the original image. For example, in a digital video camera (hereinafter sometimes simply referred to as a video camera), when correcting a vibration in a still image or the like, an angular velocity sensor or the like is used to detect a locus of camera shake at the time of imaging, and after imaging is performed based on the detected shake locus. Scheduled image restoration operations.

[0003] It has been proposed to use a point spread function (PSF) to correct for vibrations in the process of restoring an image without any blurring. When utilizing this point spread function, the image can be rest...
