Movement vector detection apparatus. |
摘要 |
<p>A movement vector detection apparatus has a detecting circuit for detecting a movement vector of an image with relation to a change amount of image density value in a determined time at an arbitrary position of the image and a space gradient of image signal at the arbitrary position, and a setting circuit for suitably setting a dimension and a shape of a unit operation area to output the movement vector in response to a space frequency of the input image. <IMAGE></p> |
