ABSTRACT:
A moving picture encoder which is able to improve the encoding efficiency wherein a controller controls an inter/intra mode switch for generating intra and inter signals Y2 and Y4, these signals being stored in a memory. A combining unit generates a combination pattern from the intra and inter signals Y2 and Y4 stored in the memory. An information amount estimator estimates the information amounts concerning the signals Y2 and Y4 and combination pattern. A minimum information amount determining unit determines the minimum one of the estimated information amounts. The controller causes a selector to select the signal or combination pattern that corresponds to the minimum information amount for quantizing and transmitting the result to a succeeding stage.
