IMAGE PROCESSING DEVICE, IMAGING APPARATUS, PARAMETER GENERATING METHOD, IMAGE PROCESSING METHOD, AND PROGRAM

摘要

A restoration processing section 38 performs restoration processing using a restoration filter based on a point spread function for image data. An outline enhancement processing section 39 performs sharpening processing using a sharpening filter for image data. A sharpness restoration control section 37 acquires a total sharpness restoration rate based on the restoration rate (restoration strength magnification U) of the image data based on the restoration processing and the sharpening rate (sharpening strength magnification V) of the image data based on the sharpening processing, acquires one of the restoration rate and the sharpening rate, and calculates the other one of the restoration rate and the sharpening rate based on the total sharpness restoration rate.

主权项

1. An image processing device, comprising:
a restoration processing unit that performs restoration processing using a restoration filter based on a point spread function for image data that is acquired from an imaging element by imaging a subject using an optical system; a sharpening processing unit that performs sharpening processing using a sharpening filter for the image data; and a sharpness restoration control unit that is able to adjust a restoration rate of the image data based on the restoration processing and the sharpening rate of the image data based on the sharpening processing by controlling the restoration processing unit and the sharpening processing unit, wherein the sharpness restoration control unit acquires a total sharpness restoration rate based on the restoration rate and the sharpening rate, acquires one of the restoration rate and the sharpening rate, and calculates the other one of the restoration rate and the sharpening rate based on the total sharpness restoration rate.
