Abstract: In one embodiment of the present invention a camera system includes a frame screener that configures an image signal processor (ISP) to ignore pixel data that does not contribute to image quality. For each image frame, the frame screener processes packets of pixel data. If the pixel data included in a particular packet is associated with an overflow state, then the frame screener determines whether the image frame should be discarded based on the number of processed pixels associated with the image frame and a minimum pixel threshold. If the frame screener determines that the image frame should be discarded, then the frame screener configures the ISP to bypass any memory and computational operations associated with the packet of pixel data. Advantageously, because the ISP disregards extraneous pixel data, the ISP may perform fewer operations and consume less power than an ISP included in a conventional camera system.
