Patent ID: 8482596

Claim:
An image adjusting method, comprising: providing a first image signal comprising a first data enable signal and a first image data signal comprising pixel data, wherein the first data enable signal has a first data enable duration; storing the pixel data of the first image signal in a memory; generating a second data enable signal, wherein the second data enable signal has a second data enable duration; detecting a first reference point of the first data enable signal to generate a first detection signal, and detecting a second reference point of the second data enable signal to generate a second detection signal; generating an adjustment value according to the first detection signal and the second detection signal; and generating a read clock and adjusting the read clock according to the adjustment value; wherein, the second data enable signal includes a second data enable duration, the first data enable duration and second data enable duration correspond to a same image frame of the first image signal, and the second data enable duration overlaps the first data enable duration; and wherein, the first data enable duration indicates a position of the pixel data corresponding to the image frame in the first image data signal, and the second data enable duration indicates a position of the pixel data corresponding to the image frame in a second image data signal.
