摘要 |
The present invention enables a movement vector of a moving object to the detected, by detecting a mixture ratio indicating the proportion of mixing with an image, or taking into consideration a region mixed with the image. A weighted frame difference computation unit 3423 outputs weighted difference. A movement compensation unit 3424 and a correlation value computing unit 3427 compute the correlation between a block of interest containing each pixel of interest of weighted difference image data, and a corresponding block of weighted difference image data of an adjacent frame. A maximum value judgment unit 3428 detects at least one of weight and a movement vector wherein correlation between weighted difference image data is greatest. The present invention can be applied to signals processing device s for processing images.
