Abstract:
1. A motion detection apparatus detecting motion in an image, the motion detection apparatus comprising: a processor; a black-and-white signal motion detector adapted to receive a first frame signal indicating a previous frame, a second frame signal indicating a present frame, a third frame signal indicating a next frame, and a black-and-white motion threshold value, to determine whether there is motion in a black-and-white image, and to output a black-and-white motion flag; a first color signal motion detector adapted to receive the first frame signal, the second frame signal, the third frame signal and a first color motion threshold value, to determine whether there is first color motion in a color image, and to output a first color motion flag; a second color signal motion detector adapted to receive the first frame signal, the third frame signal, and a second color motion threshold value, to determine whether there is second color motion in the color image, and to output a second color motion flag; and a final motion flag output unit adapted to receive the black-and-white motion flag, the first color motion flag, and the second color motion flag, and to output a final motion flag.
