Claim One:
1. A method for implementing motion detection, wherein the method comprises: obtaining a pixel value of a current image to be detected in a video image sequence, a pixel average value of same positions in a preset number of frame images before the image to be detected, and scene luminance values of the preset number of frame images before the image to be detected; obtaining a pixel scene luminance value by calculation according to the pixel value, and obtaining an average scene luminance value by calculation according to the scene luminance values of the preset number of frame images before the image to be detected; obtaining a pixel motion detection value P1 according to the pixel value and the pixel average value, and obtaining a scene luminance motion detection value P2 according to the pixel scene luminance value and the average scene luminance value; and obtaining an integrated motion detection value P3 by integrating the P1 and P2, and detecting, according to the P3, whether the image to be detected comprises a motion image region.
