Motion picture coding apparatus |
摘要 |
A motion picture coding apparatus for performing predictive coding on a high-resolution picture signal and coding a low-resolution picture signal obtained by converting the high-resolution picture signal. One field is thinned out from one frame of a picture by a field skip circuit 102, the other field is down-sampled by a down-sampling circuit 29, thereby forming a low-resolution picture. A low-resolution predictive signal, obtained by up-sampling the low-resolution picture by an up-sampling circuit 35, and a high-resolution predictive signal, which is produced from a high-resolution picture and corresponds to the thinned-out one field, are alternately combined by a predictor 104 to form a predictive signal.
