Abstract: A device for image processing includes a video signal receiver, for receiving at least one video signal, wherein an image frame of the at least one video signal includes: a plurality of pixel groups; a color engine; and an output stage, coupled to the color engine, for outputting the adjusted at least one video signal. The color engine includes: a local adjusting unit, configured to locally adjust at least one of color hue, luminance factor and saturation of a specific pixel group of the pixel groups without adjusting any other pixel group of the pixel groups, wherein the specific pixel group has color hue in a predetermined range that is a part of a full range of color hue; and a global adjusting unit, configured to globally adjust at least one of color hue, luminance factor and saturation of each of the pixels of the image frame.

Abstract: A device for image processing includes: a video signal receiver, for receiving at least one video signal; a color engine, comprising a local adjusting unit, for dividing pixels of an image frame of the at least one video signal into multiple pixel groups according to luminance factors of the pixels in HSI color space and adjusting the luminance factors of a specific pixel group of the pixel groups having luminance factors in a predetermined range that is a part of a full range of luminance factor by moving the pixels of the specific pixel group from a region to another region of the HSI color space without changing color axes of the HSI color space.
