MOTION VECTOR DETECTING DEVICE

摘要

PURPOSE:To prevent a motion vector from being misdetected by providing a gyroscope for finding the angular displacement between frames in the direction of an image pickup device to the image pickup device which outputs an image signal. CONSTITUTION:The object image area 20 of a last frame and the object image area 21 of a current frame are inputted to the image pickup device 1 and converted photoelectrically to output the image signal. At this time, the center of the image area 2 is at a point (a) and the center of the image area 21 is at a point a'. For example, the device 1 is panned between the last frame and current frame to generate a deviation by the motion vector DELTAx (DELTAx=DELTAh+DELTAv, where DELTAh is the horizontal component of the motion vector and DELTAv is the vertical component of the motion vector). The gyroscope 3 in the device 1 detects the horizontal and vertical angular displacement values DELTAwh and DELTAwv between the frames and outputs them from an angular displacement output terminal 5. The angular displacement values DELTAwh and DELTAwv are information for finding the motion vector DELTAx, which is calculated by a device which receives the angular displacement values DELTAwh and DELTAwv.
