摘要

PROBLEM TO BE SOLVED: To provide a novel moving picture coding technology of improving a coding efficiency by suppressing variations of a Lagrange's multiplier λ during the coding for determining a coding syntax through the calculation of a code amount distortion D and a code amount R.;SOLUTION: A flowchart for denoting an example of moving picture coding processing flows includes: a step S1 of setting an initial value of a quantization parameter value Q and the predetermined Lagrange's multiplier λ; a step S5 of determining objects of a plurality of quantization parameter values Q for each block of coding object; a step S6 of selecting a coding mode and a quantization parameter value Q for minimizing a D+λR among sets of objects comprising coding modes and a plurality of the quantization parameter values Q with respect to the same Lagrange's multiplier λ and coding a coding object block; a step S12 of repeating the coding steps above for each coding object block; and changing the Lagrange's multiplier λ independently of an opportunity for determining the object of the quantization parameter values by each number of blocks.;COPYRIGHT: (C)2006,JPO&NCIPI
