Abstract: A display driving apparatus and a method thereof are provided. The apparatus includes a memory unit, a compression and decompression unit, a data selection unit, and a display accelerating unit. The memory unit is coupled to the compression and decompression unit and stores only a compressed frame to save memory space in the apparatus. The data selection unit determines whether an error is caused to a frame through data compression and decompression. When the error is greater than a predetermined value, the display accelerating unit turns off an overdriving process upon the pixels to avoid image distortion. The data selection unit also determines whether the frames are static or dynamic in order to determine whether to turn on the overdriving process.

Abstract: An apparatus and the method which implement color dithering having an extended period for preventing perceivable dithering noise caused by the asymmetry and un-ideal characteristics existing in a display system are provided. The apparatus includes a separator, a carry generator, an adder and a limiter. The separator receives a color value and separates the color value into a high-bit color value and a low-bit color value. Then the carry generator provides a carry value to be either one or zero, according to a random number from a random number generator and the low-bit color value. The adder adds the high-bit color value and the carry value, and provides the result as a tentative output value. Finally, the limiter receives the tentative output value and outputs the smaller value of the tentative output value and a pre-set upper limit.

Abstract: An image processing method and device thereof are provided. In the method, at least one input signal is received and a control signal is inputted. Then, at least one region of image signal is selected from the input signals to be processed according to the control signal. Thereafter, an output signal is generated by combining the processed region of the image signal and the other regions of image. Different setting of processing parameters can be applied to different regions of image according to the users' setting. The control signal may comprise a region selection signal and/or a parameter-setting signal. Therefore, at least one of the input signals may be selected according to the selection signal and be adjusted according to the parameter setting signal. Or, an image region of the input signal(s) may be selected according to the area selection signal and be adjusted according to the parameter setting signal.
