ABSTRACT:
A method for video processing which provides a scaled image using two different clock frequencies is provided. The method receives source pixel data using a first clock signal and scales the source pixel data to destination pixel data. After that, the destination pixel data is provided using a second clock signal having a second clock frequency and a third clock signal having a third clock frequency during blanking period and active period, respectively.
