Title:
IMAGE CAPTURE DEVICE, IMAGE PROCESSING DEVICE AND IMAGE PROCESSING PROGRAMME
Document Type and Number:
WIPO Patent Application WO/2011/114611
Kind Code:
A1
Abstract:
The disclosed image capture device is provided with: a plurality of image capture elements (310a, 310b); an optical element (light incidence section) (315) which, during exposure time, sequentially allows the incident light to enter into each image capture element (310a, 310b), according to a time encoding pattern; a hand-shaking detection unit (345) which detects hand-shaking occurring during exposure time, and generates hand-shaking information showing the tracks of the hand-shaking; and an image processing unit (220) which processes a plurality of images acquired by the plurality of image capture elements (310a, 310b). The image processing unit (220) comprises: a PSF determination unit which determines the point spread function defining the blur caused by hand-shaking for each image, on the basis of the hand-shaking information and the time encoding pattern; an image restoration unit which uses the point spread function to restore each image; and an image combination unit which combines the plurality of restored images.
