ABSTRACT:
A method for capturing images includes associating the pixels with tiles. An input data sequence representing respective current values of the pixels of a currently-captured image frame is accepted. Within each of at least some of the tiles, the current values are compared with respective reference values of the pixels of a reference frame stored in a frame buffer in order to detect variations between the current and reference values.When a variation is detected at a given pixel, the current value is written into the frame buffer in place of a corresponding reference value, and the tile is marked as a changed tile. Subsequent pixel values belonging to the changed tile are written into the frame buffer without comparing the current values of the subsequent pixels to the respective reference values, thereby replacing the reference frame with the currently-captured image frame.
