Title:
Image decoding unit
Document Type and Number:
Japanese Patent JP6084732
Kind Code:
B2
Abstract:
An apparatus for encoding an image determines additional information for generating a prediction block included in an additional information container received, and an intra prediction mode of a current prediction unit using available intra prediction mode candidate information of the current prediction unit, generates reference pixels that are not in a unavailable position for generating an intra prediction block by using available reference pixels, adaptively filters the reference pixels close to the current prediction init based on the determined intra prediction mode of the current prediction unit or size information of the current prediction unit, and generates a prediction block of the current prediction unit using the reference pixels corresponding to the determined intra prediction mode of the current prediction unit. Therefore, the present invention can improve image compression ratio by generating the prediction block close to an original image.
