Abstract: An image processing apparatus includes a first timing generator, a second timing generator and an image adjusting unit. The first timing generator is utilized for generating a plurality of first driving signals, where the first driving signals are utilized to define a position of a first window. The second timing generator utilizes its own hardware to generate a plurality of second driving signals without utilizing software, where the second driving signals are utilized to define a position of a second window, and the second window is within the first window. The image adjusting unit is utilized for adjusting image data to generate adjusted image data according to the first driving signals and the second driving signals.
