Patent Images

1. A method of processing imaging signals, the method comprising:

  • receiving image data from an imaging array;

    storing the image data in a FIFO memory;

    updating a FIFO counter to maintain a count of the image data in the FIFO memory in response to memory reads and writes;

    comparing the count of the FIFO counter with a FIFO limit;

    generating an interrupt signal to request a processor to transfer image data from the FIFO memory in response to an interrupt enable signal being valid and the count of the FIFO counter having a predetermined relationship to the FIFO limit; and

    transferring image data from the FIFO memory to the processor in response to the interrupt signal.
