Abstract
A decoding apparatus includes a distribution generating section and a correcting section. The distribution generating section generates a frequency distribution of quantization index values. The correcting section corrects dequantization values corresponding to the quantization index values based on the frequency distribution of quantization index values generated by the distribution generating section.
Claims20
A decoding apparatus comprising:
- a distribution generating section that generates a frequency distribution of quantization index values;
- and
- a correcting section that corrects dequantization values corresponding to the quantization index values based on the frequency distribution of quantization index values generated by the distribution generating section.
A dequantizing method comprising:
- generating a frequency distribution of quantization index values;
- and
- correcting dequantization values corresponding to the quantization index values based on the generated frequency distribution of quantization index values.
A storage medium readable by a computer, the storage medium storing a program of instructions executable by the computer to perform a dequantization function comprising the steps of:
- generating a frequency distribution of quantization index values;
- and
- correcting dequantization values corresponding to the quantization index values based on the generated frequency distribution of quantization index values.
