Title:
Image processing device and image processing program
Document Type and Number:
Japanese Patent JP6341087
Kind Code:
B2
Abstract:
Provided is an image processing device in which an excellent PSF estimation accuracy can be obtained. This image processing device (1) is characterized in being provided with: a blurred image generation unit (13) for generating a blurred image from the input image; a region identification unit (11) for dividing a region in the input image into a non-effective region and an effective region; a weight mask creation unit (12) for creating a weight mask for causing the weight to be larger in the non-effective region than in the effective region, and causing the weight to decrease, in the effective region, according to the distance from the boundary with the non-effective region; an analysis image generation unit (14) for adding the blurred image weighted using the weight mask created by the weight mask creation unit (12) and the input image weighted using a mask obtained by inverting the aforementioned weight mask, and generating an analysis image; and a PSF estimation unit (15) for estimating the point-spread function using the analysis image.
