Document Type and Number:
Japanese Patent JP6552375
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform excellent image restoration processing while shortening the time required for the image restoration processing.SOLUTION: An image processing device 104 generates an image restoration filter by using OTF data corresponding to an imaging parameter when an input image is generated, and performs image restoration processing using the image restoration filter on the input image. The device stores the OTF data used for generating the first filter as the image restoration filter for the first image as the input image into storage means 108 while associating the OTF data with the imaging parameter of the first image. When a second filter as an image restoration filter for a second image as an input image different from the first image is generated, available OTF data as OTF data associated with an imaging parameter which is coincident with the imaging parameter of the second image or is different from the imaging parameter of the second image by a predetermined value or less is searched from the OTF data stored in the storage means, and the second filter is generated by using the available OTF data.SELECTED DRAWING: Figure 1
