1. A power management method comprising:
- receiving image data;
determining a segment mode for the received image data;
selecting a portion of the received image data corresponding to the determined segment mode;
accumulating a value of the selected portion of the received image data;
comparing the accumulated value to a threshold value; and
generating an interrupt signal if the accumulated value exceeds the threshold value.
