Claim One:
1. A method for motion detection, the method comprising: obtaining a pixel value at a position of a current image in a video image sequence, a pixel average value in a preset number of frame images before the current image corresponding to same position as the pixel value of the current image, and scene luminance values of the preset number of the frame images before the current image; calculating a pixel luminance value based on the pixel value, and calculating an average scene luminance value based on the scene luminance values; obtaining a pixel motion detection value (P 1 ) based on the pixel value and the pixel average value, and obtaining a luminance motion detection value (P 2 ) based on the pixel luminance value and the average scene luminance value; and obtaining an integrated motion detection value (P 3 ) by integrating P 1 and P 2 , and determining, based on P 3 , whether the current image comprises a motion image region.
