Abstract: An image processing method is provided. The image processing method includes: performing dynamic brightness control on an input image to determine a brightness gain for the input image; performing texture analysis on the input image based on blocks to determine filter indexes for the input image; performing color conversion with edge protection on the input image according to the brightness gain; and performing sub-pixel adjustment on the input image according to the filter indexes and a pixel arrangement of a display panel, so as to output an output image. An image processing apparatus is also provided.
