Abstract
PURPOSE:To efficiently encode a picture signal by assigning an evaluation function of a block succeeding block according to the sum of the counted value of the sample number of a current block. CONSTITUTION:The data of a register 5 is subtracted in a subtracter 6 from sampling data to store the absolute value of the value in an absolute value circuit 7. Then, a sampling block Fs is inputted to a counter to count the sampling number. When the output of the absolute value circuit 7 is larger than the output of a ROM circuit 8, a comparator 9 outputs an output to feed the value Di of the counter 4 to an adder 12 and a buffer memory 10 and feeds the code Si of the output of the subtracter 6 to the buffer memory 10. Simultaneously, a value obtained by adding an initial value to the output value of the ROM 8 is latched to the register 5, the counter 4 is reset, the adder 12 adds the contents of a register 13 to the value of the fed Di and stores in the register 13.
