Intra prediction apparatus and intra prediction method

Abstract

The present invention provides an in-plane prediction device capable of avoiding the hazard problem and improving the effect of shortening the time. The in-plane prediction means (11) includes a method for performing in-plane prediction in units of second blocks (blocks) in which a first block (macroblock) constituting an image is divided into a plurality of second blocks (blocks), and at the same time performs plane prediction on the entire first block. Intra-prediction includes a prediction unit (113), an orthogonal transformation-quantization unit (115), an inverse-orthogonal transformation-inverse quantization unit (116), an adder (117) and an in-plane prediction device for controlling parallel execution of related predictions. unit (113), orthogonal transform and quantization unit (115), inverse orthogonal transform and inverse quantization unit (116), control unit for in-plane prediction of the block of the adder (117) and in-plane prediction of the whole macroblock (119 ).

Description

technical field [0001] The present invention relates to an in-plane prediction device and an in-plane prediction method related to image coding, and in particular to a technology that can improve the coding efficiency of in-plane prediction using H.264 and other in-plane prediction. Background technique [0002] In recent years, with the popularization of communication infrastructure such as broadband and the decline in the prices of large-capacity storage devices such as personal computers, HDDs and DVDs, and memory cards, ordinary consumers have the ability to edit, store, transmit, and carry images. environment, so more users are emerging. [0003] In this way, on the one hand, the scenes of ordinary consumers processing images are increasing, but on the other hand, even if the performance of personal computers is continuously improved, better performance in image processing cannot be obtained. For example, if the amount of image information is very large, it takes a lot...

Problems solved by technology

[0018] In addition, for 16×16 macroblocks, they are also processed sequentially, so the effect of shortening the time is also very low

[0019] In addition, in order to perform in-plane prediction processing in an order different from the standard encoding order, a new problem arises in that additional processing and circuits for temporarily storing the processing results are also required
