Abstract
An image scaler includes a horizontal downscaler, a horizontal upscaler, and a vertical scaling unit. The horizontal downscaler is configured in front of the vertical scaling unit and the horizontal upscaler is configured in back of the vertical scaling unit, so as to operate in coordination with a selective control method. The selective control method controls an image input route depending on horizontal downscaling or upscaling requirements, so as to choose to go through or to bypass the horizontal downscaler or the horizontal upscaler to horizontally and vertically resize an image. In this way, the input signal is processed in only two stages, so that the present invention can not only reduce the process loading of the huge amount of the data volume in the final stage, and also can reduce power consumption.
