Title:
IMAGE-PROCESSING DEVICE, IMAGE-CAPTURING DEVICE, IMAGE-PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2014/155754
Kind Code:
A1
Abstract:
Recovered image data is acquired by subjecting original image data, which is acquired from an image-capturing element by capturing an image of a subject by using an optical system, to a restoration process using a restoration filter based on the point spread function of the optical system. Said restoration process is executed in a point-image restoration processing unit (36) with respect to color data of the original image data that has been subjected to tone correction by a logarithming process. Said restoration filter may be constituted by: a filter coefficient corresponding to the image data before being subjected to the logarithming process; or a filter coefficient corresponding to the image data after being subjected to the logarithming process. By thus performing the restoration process so as to be capable of flexibly accommodating various characteristics of the original image, it is possible to reduce degradation in image quality, such as ringing, in the recovered image.
