ABSTRACT:
A method of managing power consumption in a device, such as a video image processing device for processing data from one or more pixels, includes forming a frame of an image. The method further includes determining one or more regions of interest in the image, identifying one or more pixels located in the one or more regions of interest, and processing the one or more identified pixels in a predetermined manner. Power for at least part of the device is switched off if no pixels are identified in a region of interest within a predetermined period of time.
