摘要： When a number of samples which are less than a first reference value is a second reference value or less, a second encoding mode is selected. In the second encoding mode, when a difference value that is obtained by subtracting a value corresponding to the quantized normalization value from a value corresponding to the magnitude of each sample is positive and the sample is positive, the difference value is set as a quantization candidate corresponding to the sample; when the difference value is positive and the sample is negative, the sign of the difference value is reversed and the result is set as the quantization candidate corresponding to the sample; and a plurality of quantization candidates are jointly vector-quantized to obtain a vector quantization index. When the second encoding mode is not selected, a first encoding mode other than the second encoding mode is selected.
