Abstract

A method and apparatus for minimizing mean calculation rate in a processing system (510) performing active addressing calculations on a frame of data for driving a display (100) having a plurality of electrodes (104, 106) comprise a monitor (700) for monitoring (1506) pixel values in the frame of data to be processed and displayed. A comparator (720) compares (1508) adjacent monitored pixel values to determine (1510) resolution of the data, and thereafter a controller (622) controls (1610, 1612, 1614) the processing system (510) to minimize the mean calculation rate by modifying the active addressing calculations in accordance with the resolution determined.
