1. An image processing apparatus comprising:

  • input means for inputting moving-picture information including a plurality of frames;

    processing means for obtaining a difference between successive frames on each pixel of the moving-picture information;

    summation means for obtaining the sum of the difference between the successive frames on each pixel;

    thinning means for thinning out frames of the input moving-picture information;

    determination means for determining whether the sum of the difference obtained by said summation means is less than a threshold;

    output means for outputting compressed information for the input moving-picture information; and

    control means for controlling said output means so as to output moving-picture information thinned out by said thinning means as the compressed information where the sum of the difference is determined to be less than the threshold by said determination means and so as to output the difference obtained by said processing means as the compressed information where the sum of the difference is determined not to be less than the threshold by said determination means,wherein said processing means and said thinning means process the same moving-picture information simultaneously, and said control means controls said output means to select one of the results of processing by said processing means and said thinning means as the output.
