MOVING IMAGE CODING APPARATUS, METHOD AND PROGRAM

摘要

The moving image coding apparatus generates at least one motion prediction information for prediction-coding a coding target image of color components, for each color component, determines a correlation relationship of at least one motion prediction information of each of the generated color components, determines a color component which is to be a correction target, on the basis of a result of the determination of the correlation relationship, and corrects at least one motion prediction information of the determined color component using the motion prediction information corresponding to at least one color component among the other color components.

1. A moving image coding apparatus for motion-prediction coding a moving image including a plurality of color components on a color component basis, comprising:
a color component obtaining unit that obtains the plurality of color components configuring the moving image; a prediction unit that generates at least one motion prediction information for prediction-coding a coding-target image of the obtained color components, for each color component; a correction unit that determines a correlation relationship of at least one motion prediction information of each color component generated by the prediction unit, determines a color component which is to be a correction target, on the basis of a result of the determination of the correlation relationship, and corrects at least one motion prediction information of the determined color component using the motion prediction information corresponding to at least one color component among the other color components; and a coding unit that obtains coding parameters from the correction unit, and prediction-codes the coding-target image of each color component using the obtained coding parameters.
