1. A power management method comprising:
receiving image data;
determining a color depth of the received image data;
selecting at least a portion of the received image data, wherein the portion of the received image data includes data for one or more of a plurality of pixels of the received image data;
accumulating a brightness value of the selected portion of the received image data, wherein the brightness of each of the one or more pixels within the selected portion is calculated using the determined color depth;
comparing the accumulated brightness value to a threshold value; and
generating an interrupt signal if the accumulated brightness value exceeds the threshold value.
