Abstract
An image encoding apparatus comprises a selector configured to select, from a set of candidate prediction operations each defining at least a prediction direction, a prediction operation for prediction of samples of a current region of a current image, the current region comprising an array of two or more rows and two or more columns of samples; and an intra-image predictor configured to interpolate predicted samples of the current region with respect to one or more of a group of reference samples being samples decoded from previously encoded samples of the current image, the group of reference samples being selected in dependence upon a prediction direction, defined by the selected prediction operation, between a current sample to be predicted and a reference position amongst the reference samples, in which the intra-image predictor is configured to apply an interpolation process to the group of reference samples in order to generate each predicted sample; in which the intra-image predictor is configured to apply a different respective interpolation process for a plurality of subsets of the predicted samples, according to a relationship between a plurality of interpolation processes and a corresponding plurality of subsets of sample positions in the array of samples.
