摘要 |
A video encoding device includes control means 12 for supplying parameters used in the quantization process to the quantizing means 11, wherein the quantizing means 11 includes: a two-dimensional table 13 storing result values of calculation which is a part of the quantization process, each of the result values is calculated by using a value based on a quantization parameter and a quantization weighting coefficient used for visual image quality control; and computing means 14 for inputting a result value corresponding to two parameters supplied from the control means 12, and generating the quantization coefficient by using the input result value. |
