Abstract:
1. A video frame buffer comprising: an image stream input for receiving image frames from an image sensor over a communication link, with the image frames having an input first frame format and comprising blanking; a frame processor for modifying the received image frames to an output second frame format by removing the blanking to reduce an overall amount of information in the received image frames, with said frame processor being set to the input first frame format and the output second frame format; a memory controller for receiving the modified image frame; a memory for selectively buffering the modified image frames before outputting the modified image frames in the second frame format; a memory driver coupled to said memory controller for controlling timing of writing to said memory and reading from said memory; a communication output for receiving the modified image frames in the second frame format from said memory; and a second frame processor coupled between said image stream input and said communication output so as to selectively bypass said memory, said memory driver and said memory controller, said second frame processor for modifying the received image frames to the output second frame format by removing the blanking to reduce the overall amount of information in the received image frames, with said second frame processor being set to the input first frame format and the output second frame format.
