Claim Text:
1. A computer-implemented method for determining a display mode for a display device based on a rate of change of content across display frames, the method comprising: receiving a plurality of image surfaces from a frame buffer memory, wherein the plurality of image surfaces includes a base surface and an overlay surface; incrementing a first counter that resides within a frame compositor in response to receiving the plurality of image surfaces; composing, via a combine unit that resides within the frame compositor, a current display frame based on the base surface and the overlay surface; calculating, via a cyclic redundancy check (CRC) calculator that resides within the frame compositor, a first numerical code associated with content of the current display frame; comparing, via a comparator unit that resides within the frame compositor, a second numerical code associated with the content of a previous display frame to determine whether the current display frame is identical to the previous display frame; and if the current display is identical to the previous display, then incrementing a second counter that resides within the frame compositor; or if the current display is not identical to the previous display, then not incrementing the second counter, wherein a rate of change of display frame content is calculated by dividing the count of the second counter by the count of the first counter; wherein the plurality of image surfaces does not include a cursor surface, and the current display frame comprises an intermediate display frame.
