A CMOS imaging sensor with ernbedded feature extraction capability operatable in different modes by a method that includes the steps of: (a) operating the CMOS imaging sensor in a motion-detecting mode at a first power level using circuitry on the imaging sensor that generates motion data based on received images detected by pixels in the pixel array; (b) switching the imaging sensor from the motion-detecting mode to a feature extraction mode in response to detecting motion; and (c) operating the imaging sensor in the feature extraction mode at a second power level that is higher than the first power level. |
