摘要 |
In an apparatus for judging a hand movement of an image, pixels where absolute values of differences between image data of respective pixels of blocks of a current frame and image data of representative point pixels of blocks of an earlier frame read out from a representative point memory satisfy a predetermined condition are judged by a condition judgment circuit to form a frequency distribution table corresponding to the judged result by a frequency distribution table formation circuit to calculate, on the basis of the frequency distribution table, the number of coordinates having a frequency value greater than a predetermined value in the vicinity of a coordinate designated by a motion vector of an image to judge the motion vector to result from a hand movement when the calculated value is less than a predetermined value. <IMAGE> |
