ABSTRACT:
In a picture processing apparatus such as a camera, monitor camera, television and the like, an imaging device is controlled to follow a desired target object and image it in the best state. A distribution of motion vectors within a tracking vector detection area is detected, and then the most characteristic motion vector is detected. In a second embodiment a power of components in a high frequency band is detected per unit of predetermined blocks, difference data between picture data of motion pictures of the present frame and the previous frame is obtained, the power of the difference data is detected per unit of predetermined blocks, and an edge having movement is detected on the basis of the detection result.
