Abstract
A video signal processing apparatus includes circuitry which generates a motion vector which represents the amount and direction of motion which occurs between consecutive frames of a video signal and for determining if the vector indicates that an image sensing device is undergoing undesirable motion. The circuitry is further arranged to produce a correction signal based on the motion vector and delay the video signal in accordance with the same. A memory is provided in which video information relating to a peripheral portion of the effective picture area of the image sensing device, is stored and operatively connected with a selector which selects one of the delayed video signal and peripheral portion data stored in the memory in accordance with the correction signal.
Claims4
A video signal processing apparatus for processing a video signal generated by an image device in a video camera comprising:
- means for generating a motion vector representing a motion amount and a motion direction between consecutive frames of said video signal;
- means for judging whether said motion vector represents the undesired motion of said image sensing device or not;
- correction signal generating means for generating a correction signal in accordance with said motion vector;
- delay means for delaying said video signal in response to said correction signal;
- memory means for storing a video information corresponding to a peripheral portion of an effective picture area of said image sensing device;
- and
- selection means, responsive to said correction signal, for selecting at least one of the outputs of said memory means and said delay means, and for outputting a video signal.
