In addition, by integrating different recognition methods, the amount of system operation can be reduced, and the operation speed can be thereby improved.

Abstract: An image data compression method is disclosed. Firstly, check a variance between a first image data and a second image data for comparing the variance with a threshold value. When the variance is smaller than a threshold value, compare the first image data with the second image data to generate a motion vector and compress the motion vector. Then calculate the first image data and the second image data according to the motion vector so as to get an offset value of the motion vector. Next, encode the offset value of the motion vector, compress the offset value of the motion vector, and encode as well as compress the first image data. Thus the compression ratio is improved and image distortion is avoided.
