ABSTRACT:
A signal is quantized, and a quantized signal is thereby obtained. The quantized signal is separated into a binary signal, which represents whether the signal values of the quantized signal are equal to zero or are other than zero, and a sign and intensity signal, which is constituted of a sign and intensity with respect to signal components of the quantized signal having signal values other than zero. The binary signal is converted such that the information of the binary signal, which represents N number of picture elements, may be converted into a signal, which represents a single picture element and is composed of Nnumber of bits. The converted binary signal, which has been obtained from the conversion, the sign and intensity signal are then encoded. The encoding efficiency is thereby enhanced, and the amount of the signal after being encoded is kept small.
