Abstract
PURPOSE:To obtain the reproduced image of a satisfactory picture quality with small encoding quantity by dividing an inputted image into a block composed of plural picture elements, after that, selecting one encoder out of the plural encoders based on a parameter to express the signal distribution in the block for every block and executing an encoding. CONSTITUTION:A signal distribution computing part 3 in the block computes the parameter to express a block signal distribution in a buffer memory 2 and the parameter is sent to an encoder selecting part 4. The encoder selecting part 4 selects one encoder out of the plural encoders, whose quantizing characteristics are different, prepared in advance to an encoder memory 5, and then sets it to a variable sampling density encoding/decoding part 6. In the variable sampling density encoding/decoding part 6, an inputted image signal and a forecasted image signal are subtracted by a subtracter 12, a forecasted error signal is obtained and said forecasted error signal is sent to a variable sampling density encoding circuit 10 and a compressing code is outputted. Said compressing code goes to be a reproduced image signal by a variable sampling density decoding circuit 11 and simultaneously is sent to a forecasting circuit 9.
