Claim:
1. An image coding device including a video coded data converter that converts each scene video data in video coded data compliant with a first video coding method into video coded data compliant with a second video coding method by selectively applying a prediction reference using other scene video data to said each scene video data, wherein when converting coded data about each scene video unit in first video coded data, said video coded data converter retrieves coded data about another scene video unit which is to be used for prediction reference, determines whether or not to use the coded data about the scene video unit which said video coded data converter has retrieved for the prediction reference, and converts the coded data about said first scene video unit into video coded data compliant with the second video coding method, and also generates metadata showing whether or not the coded data about the scene video unit which said video coded data converter has retrieved is used for the prediction reference.
