Embodiment Construction

[0091] Embodiments of the video processing device of the present invention will be described below with reference to the drawings.

[0092] In the moving image processing device of the present invention, a coprocessor for performing multi-computing processing, that is, motion detection processing, is added to the processor for comprehensively managing the encoding or decoding processing of moving images, and the coprocessor is provided with a buffer. A device has a structure that is accessed by multiple banks by interleaving. In addition, the step of reading image data in the motion detection process is carried out in a predetermined manner, and there is also provided a component that can appropriately respond to the reduction of the read image data.

[0093] With this configuration, the video processing device of the present invention can reduce the amount of data transfer and perform appropriate coding when performing video coding.

[0094] In addition, in the moving image ...

Abstract

To perform an adequate encoding process while cutting a data transfer amount in an encoding process of moving images. A moving image processing apparatus 1 has a motion detection / motion compensation processing portions 80 as a coprocessor for performing a motion detection process as a process of a large calculation amount added to a processor 10 for managing an entire encoding or decoding process of a moving image, and has a buffer addressed to a plurality of memory banks by interleaving. A procedure for reading image data on the motion detection process is a predetermined method, and a section capable of adequately handling a case of reducing read image data is provided. As for the moving image processing apparatus according to the present invention, it is possible, with such a configuration, to perform an adequate encoding process while reducing a data transfer amount in the encoding process of the moving image.

Description

technical field [0001] The present invention relates to a video encoding device for encoding a video, and a video processing device for encoding or decoding a video. Background technique [0002] In recent years, moving image encoding / decoding techniques have been utilized in the case of moving image transmission over a network, terrestrial digital broadcasting, or storing moving images as digital data. [0003] Such dynamic image encoding often requires high-load processing, especially in motion detection, where there is a problem of how to perform block matching and the accompanying data transmission from the frame memory. [0004] In view of the above problems, various technical solutions have been proposed all the time. For example, Japanese Patent Application Laid-Open No. 6-113290 discloses such a technology: in the motion detection process, in order to reduce the amount of computation, all pixels are not required to acquire encoding objects. The operation of the sum ...
