摘要 |
<p>A motion compensating encoding apparatus adaptive to a motion amount adaptively generates motion-compensated pixel values for performing differential pulse code modulation of pixel values of a current image even when a current image motion amount to be motion-compensated with respect to a reference image is beyond a predetermined motion amount. The motion compensation encoding apparatus includes a global motion estimator (53) for generating a global motion vector representing spatial position difference between the reference image according to the pixel values stored in a first memory (17) and the current image according to the pixel values stored in a second memory (56), motion-compensating the reference image on the basis of the generated global motion vector and storing the pixel values of the motion-compensated reference image, a local motion estimator (54) for generating a local motion vector according to comparison of the pixel values between a current video block which is formed by the pixel values supplied from the second memory (56), and which has a size smaller than the current image and a search area formed by part of the pixel values stored in the global motion estimator (53), a motion compensator (55) for receiving the local motion vector from the local motion estimator (54) and generating motion-compensated pixel values by using the pixel values stored in the global motion estimator (53) and the local motion vector, and a unit (31) for generating a difference value between the respective pixel values of each image secondly output from the second memory (56) and the corresponding motion-compensated pixel values output from the motion compensator (55). <IMAGE></p> |
