Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/002260
Kind Code:
A1
Abstract:
In order to suppress the influence of noise fluctuations caused by an image correction based on the characteristic of an imaging optical system and generate a high-quality image, provided is an image processing device which is applied to an imaging device for acquiring an image by capturing an optical image of a subject, the optical image being formed by an imaging optical system, and is provided with: an input means which inputs the image acquired by the imaging device and optical characteristic information relating to the characteristic of the imaging optical system; an image correction means which corrects the image on the basis of the optical characteristic information; a basic noise reduction information storage means which previously stores basic noise reduction information indicating a noise amount with respect to a brightness value; a noise reduction information updating means which updates the basic noise reduction information so as to suppress fluctuations in noise amount caused by the correction of the image by the image correction means on the basis of an imaging condition when the image has been acquired and the optical characteristic information; and a noise reduction means which performs noise reduction processing of the image on the basis of the noise reduction information updated by the noise reduction information updating means.
