Abstract
A moving image coding apparatus, a code amount control method, and a code amount control program enable appropriate code amount control to be performed in units shorter than frames. The moving image coding apparatus includes a coding unit, a quantization parameter determination unit, and a target code amount setting unit. The target code amount setting unit designates the number of macroblocks and sets a target code amount as a code amount to be allocated to the designated number of macroblocks. The quantization parameter determination unit calculates, for each macroblock, a quantization parameter to be used in quantization of a current macroblock based on a sum of absolute transformed differences SATD used in a motion estimate process. The moving image coding apparatus performs quantization using the calculated quantization parameter value.
