Abstract: The present invention relates to an image generating apparatus and an image generating method. The image generating apparatus, according to an embodiment of the present invention, includes a channel dividing unit which divides an input image by RGB channels; an average value calculating unit which calculates an average value of each channel using pixel values divided by RGB channels; a chromaticity correction unit which calculates the ratio of one among the RGB channels to the remaining channels, based on the one, and globally corrects the pixels of the input image using correction parameters, based on the calculated ratio, thereby creating a corrected image; a brightness calculating unit which calculates the brightness (Y) using the corrected image; and a contrast correction unit which changes the gradation of pixels of the corrected image within a predetermined range from the minimum and maximum gradation by using the calculated brightness, and outputs a standard image.

Abstract: The present invention relates to an apparatus and method for correcting a color. The apparatus for correcting the color according to the embodiment of the present invention includes: an image extracting unit which extracts an image for estimating a color which is partially or entirely faded in an input image by applying a plurality of filters with different sizes; a correction factor calculating unit which calculates the correction factor of each extracted image by applying the filters; a correction factor integrating unit which generates a correction factor map by summing the correction factors of the pixels corresponding to the same location of each image; and a correcting unit which outputs a corrected image by applying the generated correction factor map to the pixels of the input image.
