Abstract:
In an image processing apparatus having a first image processing unit for operating at a first clock signal and a second image processing unit for operating at a second clock signal having a second frequency which is higher than the first frequency, if image data is supplied from the first image processing unit to the second image processing unit, the second clock signal is supplied to the second image processing unit when intra-line image data of the image data is being transmitted and pixel data to be processed in the image data exists. If the intra-line image data is being transmitted and no pixel data to be processed in the image data exists, no clock signal is supplied to the second image processing unit.
