MOTION VECTOR CALCULATION DEVICE AND MOTION VECTOR CALCULATION METHOD |
摘要 |
<p>[PROBLEMS] The conventional technique has a problem that when a calculated global motion vector is incorrect, a search range is difference from the original one and the possibility of incorrect calculation of the motion vector becomes high and problem that the incorrect calculation of the motion vector may cause lowering of efficiency of the dynamic image encoding. [MEANS FOR SOLVING PROBLEMS] A motion vector calculation device divides a global macro block into middle blocks and detects middle motion vectors for calculation of a global motion vector. Middle motion vectors considered to have abnormal values are excluded from the detected middle motion vectors. According to the remaining middle motion vectors, an accurate global motion vector is calculated.</p> |
