Apparatus and method for enhancing image base on luminance information of pixel

摘要

An image enhancement apparatus and method based on luminance information of a pixel. The image enhancement apparatus may determine luminance data of each of a plurality of pixels, and may adaptively determine a conversion ratio according to the luminance data to apply the conversion ratio to an input image, thereby performing image-enhancing. The image enhancement apparatus may adaptively converse the input image according to luminance data, thereby precisely and effectively performing image-enhancing.
