A thermally-directed optical imager and a method of thermally-directing optical processing are described. The thermally-directed imager includes a thermal image sensor, an optical image sensor, and a processor. The thermal and optical sensors respectively generate thermal image and optical image signals. The processor uses the thermal image signal to determine an optical processing region, which the processor uses to derive a compressed-image signal. The optical processing region may be determined by detecting a center of heat-mass associated with the thermal image signal or by performing an edge detection algorithm. In addition, the thermally-directed imager may be focused, zoomed, or centered via the thermal image signal.
