MOVING VECTOR DETECTING BDEVICE |
摘要 |
The present invention relates to a motion-vector detection device capable of detecting a motion vector between frame images accurately and promptly. The motion-vector detection device according to the present invention is a motion-vector detection device for detecting a motion vector between frame images of the preceding frame and current frame (succeeding frame), and first enhances a vertical edge of each of a plurality of image regions obtained by dividing a frame image in the vertical direction, and then obtains a vertical projection to generate projection data for one horizontal line. Next, intersections of this projection data and a first threshold value are searched, and projection data of the current frame corresponding to a motion vector detection range with each intersection placed at its center is extracted. Then, each piece of extracted projection data is added per distance from the above-mentioned each intersection, and a horizontal motion vector of the frame image is detected from the result of addition. |
