AN INTRA-PREDICTION APPARATUS FOR REMOVING A DIRECTIONAL INTRA-PREDICTION MODE FROM A SET OF PREDETERMINED DIRECTIONAL INTRA-PREDICTION MODES

摘要

The present invention relates to an intra prediction apparatus for removing a directional intra prediction mode from a set of predetermined directional intra prediction modes. This intra prediction apparatus includes a reference sample determining unit, configured to select a directional intra prediction mode from a set of predetermined directional intra prediction modes, and to determine a plurality of available reference samples, to obtain a reduced set, a plurality of directional intra, configured to remove a directional intra prediction mode from a set of predetermined directional intra prediction modes if the length L RSlonger associated with the available reference samples is less than a multiple of the length L longer of the first side of the video coding block a prediction mode removal unit, and an intra prediction unit, configured to intra-predict pixel values of pixels of the rectangular video coding block based on the reduced set. Such an intra prediction apparatus may further include an area determination unit.
