ABSTRACT:
An apparatus detecting motion in image data by compressing and encoding and a method thereof. The motion detecting apparatus has a separation unit, an operation unit and a comparison unit. The separation unit separates a bit stream in relation to a motion predicted image from a compressed encoded image bit stream. The operation unit calculates an average value of the bit stream in relation to the motion predicted image separated at the separation unit. The comparison unit detects a motion when the average value is greater than a predetermined threshold after comparing the average value and the threshold. Thus, because a motion in an input image can be detected by using a compressed encoded image bit stream, a separate circuit or input image processing is not required to detect the motion and adverse affects of camera noise on the detection results can be reduced.
