Patent ID: 8320691

Claim:
An image coding apparatus comprising: a particular region detecting unit configured to detect from an input picture a particular region including a particular picture, the particular region being detected as a region within the input picture which has a hue within a predetermined range corresponding to an average hue of the particular picture and which has an amount of movement between different frames which is equal to or larger than a threshold; a simulation picture generating unit configured to generate a simulation part picture of the particular region of subsequent frames based on a simulation by solving a discrete difference equation using initial conditions set thereto, the simulation picture generating unit being configured to obtain the initial conditions such that a difference between the generated simulation part picture and the picture of the particular region detected by the particular region detecting unit is smallest; and a coding unit configured to generate a coded stream by performing coding processing that is intra-frame coding or interframe coding on the input picture and to perform, with respect to the particular region, processing of embedding the initial conditions obtained by the simulation picture generating unit into the coded stream, instead of performing the interframe coding.
