METHOD AND APPARATUS FOR BIT RESOLUTION ENHANCEMENT AND EDGE ENHANCEMENT IN AN ELECTRONIC DEVICE

摘要

A method and apparatus for bit resolution enhancement and edge enhancement in an electronic device are provided. The method includes determining a Contour Counter (CC) and determining a type of each region of the input image, determining a Bit Resolution Enhancement (BRE) parameter and an edge enhancement parameter of each region according to the determined region type, determining a first weight for each region of the image and enhancing a bit resolution of the input image, and determining a second weight for each region of the image and performing edge enhancement for the image.
