Image motion vector detector. |
摘要 |
An image motion vector detection apparatus effectively reduces influences of false vectors arising at a certain probability and suppresses time lags. An image fluctuation stabilizer highly stabilizes images or frames without causing unnatural visual feelings. An image motion vector detection apparatus comprises means (2 to 5) for detecting motion vectors in each of motion vector detection regions defined in the whole or part of picture frame, means (12) for judging the reliability of the motion vector in each region, and signal processing means (11) which, in obtaining a motion vector of the whole or part of the frame from the motion vectors of the regions and in case the number of motion vectors judged to be reliable is more than or equal to a predetermined number, outputs a representative value of a set of the reliable motion vectors as a motion vector of the frame. |
