    摘要: A moving picture prediction method for enabling a calculation amount and a storage capacity to be reduced in a prediction about a moving picture by scaling processing is provided. A method for predicting the value P of Time T from the value P0 of Time T0 and the value P1 of Time T1 includes a step of judging whether it is possible to generate a predictive value with a predetermined significant number of bits by scaling using Time T0, T1 and T (Step S90); a step of predicting the value P from the values P0 and P1 by scaling using Time T0, T1 and T when it is possible to generate a predictive value with the predetermined significant number of bits (Step S92); and a step of predicting the value P from the values P0 and P1 without using Time T0, T1 and T when it is impossible to generate a predictive value with the predetermined significant number of bits (Step S91).

    摘要: A method of coding an original image, including: partitioning (S110) the original image into blocks; determining (S120) a coding condition for a current one of the blocks; and coding (S130) the current block according to the determined coding condition, wherein the determining (S120) of the coding condition for the current block includes calculating (S210) a first spatial-activity value indicating complexity of at least a part of regions of the current block; comparing (S220) the first spatial-activity value with a first predetermined threshold value; determining (S230), as the coding condition for the current block, a first coding condition for small partitioning size, when the first spatial-activity value is smaller than the first predetermined threshold value; and determining (S240), as the coding condition for the current block, a second coding condition for large partitioning size, when the first spatial-activity value is equal to or larger than the first predetermined threshold value.
