Abstract: An image processing method is adapted for color enhancement of an original image pixel. The original image pixel is composed of a plurality of pixel components each having a component value. The image processing method includes: determining a hue region to which the original image pixel belongs based directly on the component values of the pixel components thereof; selecting a color enhancement parameter corresponding to the determined hue region; and obtaining a color enhanced pixel according to the selected color enhancement parameter and the component values of the pixel components of the original image pixel.

Abstract: A data accessing interface between memory and source in LCD display IC includes a multiplex output module and a sequential input module. Suppose a row width of the memory is N bit. The multiplex output module is for outputting a row N-bit digital data. The multiplex output module includes a buffer for receiving the row N-bit digital data from the memory; and a multiplex unit for continuously selecting M bits from the N bit digital data to output to source. After N/M times, all of the row N bit digital data will be output to source. The sequential input module includes N latches and N/M latch control signals; when each latch control signal is active, it will latch M bit digital data from the multiplex output into M latches. After N/M latch control signals are active sequentially, the N bit digital data are stored into the N latches for source.
