Title:
IMAGE PROCESSING DEVICE, IMAGING DEVICE, COMPUTER, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/050190
Kind Code:
A1
Abstract:
Provided is a technique capable of reducing the amount of data storage by a restoration filter used in point image restoration processing while suppressing degradation of the precision of point image restoration. Statistical information (D12) relating to point image restoration of a picture is acquired, optical information (D14) indicating a point image intensity distribution of an optical system used during acquisition of the picture is acquired, and filter information (symmetry of the restoration filter, tap number of the restoration filter, etc.) of the restoration filter for point image restoration processing of the picture is calculated on the basis of the statistical information and/or the optical information. A filter coefficient (D18) of the restoration filter is computed on the basis of the statistical information (D12) and the optical information (D14) using the filter information (D16) as a constraint condition. Point image restoration processing of the picture is performed using the filter coefficient (D18) thus computed.
