Abstract: A method of processing an image data for an image processing device includes a plurality of steps. The steps include receiving the image data; storing the image data in a frame buffer of the image processing device; performing a signal processing procedure on the image data obtained from the frame buffer, to generate a final display data; restoring the final display data in the frame buffer; and entering a power saving mode after the final display data is restored in the frame buffer. In the power saving mode, the image processing device performs the following steps: turning off the signal processing circuit; and outputting the final display data restored in the frame buffer, to display the final display data.
