Claim One:
1. A video correction apparatus, comprising: a resolution adjuster configured to determine one or more resolution values and a filter coefficient of at least one filter for performing filtering process for extracting an illumination component from a color component of an input image, and adjust an initial resolution of the color component of the input image to the one or more resolution values to generate one or more resolution-adjusted images; an illumination component extractor configured to extract one or more illumination components from the one or more resolution-adjusted images by using the one or more resolution-adjusted images the at least one filter; a reflection component extractor configured to extract one or more reflection components of the one or more resolution-adjusted images by removing the one or more illumination components from the one or more resolution-adjusted images; a color adjuster configured to generate one or more sum images by using the one or more reflection components and the one or more resolution-adjusted images; and an image synthesizer configured to generate one or more readjusted images by readjusting the one or more resolutions of the one or more sum images to the initial resolution of the color component of the input image, and generate a corrected image corresponding to the color component of the input image by using the one or more readjusted images.
