It is possible to provide an operation detection device capable of accurately detecting/analyzing a position and a motion of an object image contained in a dynamic image in real time. The operation detection device includes: edge block detection means (7) for outputting an edge detection signal when an edge image is contained in an image block of the frame of the edge dynamic image; and motion detection block aggregates (8, 9) in which motion detection blocks detecting the motion of the motion detection direction are arranged to correspond tot he respective image blocks. The motion detection block generates time elapse information upon detection of an edge detection signal of an image block adjacent to the side opposite to the motion detection direction for the corresponding image block and holds the time elapse information while updating it. When an edge detection signal for the image block corresponding to the motion detection block is outputted, the time elapse information held at that moment is outputted. |
