Abstract:
1. A moving picture encoding device for, for a plurality of input image signals each having a different resolution, making a reference to an encoding result of one input image signal to encode the other input image signal, thereby to perform hierarchical encoding, characterized in: including: first image encoding means for encoding a first input image signal, generating first encoding data, and generating a decoded image signal, being a decoding result of said first encoding data; a filter for enlarging said decoded image signal so that it has a resolution identical to that of a second input image signal, and generating an enlarged decoded image signal; second image encoding means for making a reference to said enlarged decoded image signal to encode said second input image signal, and generating second encoding data; and that said second image encoding means subjects said second input image signal to a motion compensation prediction to generate a second prediction signal, subtracts said second prediction signal from said second input image signal to generate a second prediction error signal, subjects said enlarged decoded image signal to a motion compensation prediction identical to the motion compensation prediction, to which said second input image signal has been subjected, to generate a first prediction signal, subtracts said first prediction signal from said enlarged decoded image signal to generate a first prediction error signal, and adaptably regulates encoding processing of said second prediction error signal based upon said first prediction error signal.
