IMAGE PROCESSING APPARATUS AND METHOD AND IMAGE PICKUP APPARATUS |
摘要 |
The present invention allows the amount of movement indicating the movement of an object within an exposure period to be obtained. An estimated-mixture-ratio processor 401 calculates an estimated mixture ratio for each pixel and an estimated motion vector by a calculation corresponding to a model of a covered background area, and sends the calculated estimated mixture ratio and the calculated estimated motion vector to a mixture-ratio determining portion 403. An estimated-mixture-ratio processor 402 calculates an estimated mixture ratio for each pixel and an estimated motion vector by a calculation corresponding to a model of an uncovered background area, and sends the calculated estimated mixture ratio and the calculated estimated motion vector to the mixture-ratio determining portion 403. The mixture-ratio determining portion 403 sets a mixture ratio and a motion vector according to area information indicating to which of a foreground area, a background area, the covered background area, or the uncovered background area a designated pixel belongs. The present invention can be applied to image processing apparatuses. <IMAGE> |
