Abstract
A method for zooming images is provided. The method is suitable for altering the size of a source image frame in both horizontal and vertical directions to generate a destination image frame. The method for zooming images includes the following steps. First, the frequency of a horizontal sync signal is multiplied to generate an operating clock signal, wherein the horizontal sync signal is synchronized with the source image frame. Next, the source image frame is sampled by the operating clock signal to generate a sampled image frame. Then, a horizontal zooming operation is performed on the sampled image frame by using the operating clock signal to generate a horizontal image frame. Afterwards, a vertical zooming operation is performed on the horizontal image frame by using the operating clock signal to generate a vertical image frame. Finally, the vertical image frame is output as the destination image frame.
