Title:
IMAGE CORRECTION DEVICE, IMAGE CORRECTION METHOD, AND IMAGE CORRECTION PROGRAM
Document Type and Number:
Japanese Patent JP2023008397
Kind Code:
A
Abstract:
To reduce deterioration of the granularity of a captured image with a lapse of time.SOLUTION: An image correction device comprises: an acquisition unit which acquires each luminance value of a plurality of pixels; a calculation unit which calculates a pixel approximation formula obtained by approximating variation in the luminance value, with respect to each of the pixels; and a corrected image output unit which when a captured image is input, corrects the luminance value of each of the pixels of the captured image on the basis of the difference between a reference function being a function to be the reference of comparison with the pixel approximation formula and the pixel approximation formula, and thereby generates and outputs a corrected image being an image after correction.SELECTED DRAWING: Figure 2
