Abstract
Methods, systems and apparatuses for the detection of motion using statistics data already available within an imager, such as sharpness scores or brightness values. The method includes obtaining at least two sets of statistics data for respective image frames which include corresponding windows; initializing a motion counter; determining, for each window, a relative difference value for the particular window; comparing the relative difference value to a first threshold. If the relative difference value is greater than the first threshold, the method increments the motion counter; and determines if there is motion by comparing the value of the motion counter to a second threshold. The motion detection may further take into account the relative importance of certain areas of the image frame.
