Color correction apparatus and method
First Claim
1. A color correction apparatus comprising:
- a chromatic region determination module which determines a first chromatic region to which an input pixel constituting an input image belongs and a second chromatic region neighboring the first chromatic region based on specified chromatic region division information;
a polynomial regression operation module which performs polynomial regression on the first chromatic region and the second chromatic region; and
a blending module which provides corrected pixel information for the input pixel by giving weight values to results of the polynomial regression on the first chromatic region and the second chromatic region.

Abstract
A color correction apparatus and method are provided. The color correction apparatus includes: a chromatic region determination module determining a first chromatic region to which an input pixel constituting an input image belongs and a second chromatic region neighboring the first chromatic region on a basis of specified chromatic region division information; a polynomial regression operation module performing polynomial regression on the first chromatic region and the second chromatic region; and a blending module providing corrected pixel information for the input pixel by giving weight values to results of the polynomial regression on the first chromatic region and the second chromatic region. The color correction method includes: determining the first and second chromatic regions; performing polynomial regression on the first and second chromatic regions; and providing corrected pixel information for the input pixel by giving weight values to results of the polynomial regression on the first and second chromatic regions.
