摘要 |
When video images are processed by applying temporal or spatial interframe prediction encoding to each divided area, and generating a predicted image of a processing target area based on a reference frame of the processing target area and reference information which indicates a predicted target position of the processing target area in the reference frame, predicted reference information is generated as predicted information of the reference information. Reference information used when an area adjacent to the processing target area was processed is determined as predicted reference information prediction data used for predicting the reference information of the processing target area. Reference area reference information is generated using one or more pieces of reference information used when a reference area indicated by the prediction data was processed. The predicted reference information prediction data is updated using the reference area reference information. The predicted reference information is generated using one or more pieces of the updated predicted reference information prediction data. |
