FIELD: data processing.
SUBSTANCE: invention relates to intra prediction encoding/decoding of image. proposed is the internal image prediction device, which generates the prediction value using the linear interpolation in the current prediction unit horizontal and vertical directions, wherein the device comprises: coding information obtaining means configured to obtain reference samples including first angular sample, second angular sample, first side sample and the second side sample, wherein these reference samples are used for the current sample prediction; and the prediction value determiner, configured to determine the current sample prediction value based on the first angular sample, the second angular sample, first side sample and second side sample, the current block is predicted by determination of the included into the current block samples prediction values.
EFFECT: higher efficiency of image compression using different prediction directions.
