Problems solved by technology

However, for example, there are cases where the allowable range of the delay caused by the decoding process is small, and the decoding process is required to be fast and stable, as in the case of decoding a bit stream of encoded data transmitted sequentially and in the case of reading and decoding records recorded in The coded data on the medium is the same as in the case of reproducing the image

Abstract

An image processing apparatus including: an encoding section encoding image data including images from a plurality of viewpoints; an amount-of-code calculation section determining a viewpoint and a picture type of the image data encoded by the encoding section, and calculating an average amount of code using information on a past amount of code for each viewpoint and for each picture type; and an average-rate calculation section calculating an average bit rate using the average amount of code calculated by the amount-of-code calculation section for each viewpoint and for each picture type.

Description

technical field [0001] The present invention relates to image processing devices, and methods of processing images and videos. Background technique [0002] In recent years, image processing devices complying with a compression method (for example, MPEG Moving Picture Experts Group) have become popular both for information distribution at broadcasting stations and the like, and for information reception at ordinary households. In the compression method, image information is processed as digital data, and the digital data is compressed by orthogonal transformation such as discrete cosine transform and motion compensation by utilizing the redundancy unique to image information, so as to transmit and preserve image information efficiently. [0003] In addition, in recent years, a standard called AVC (Advanced Video Coding) (MPEG4part10, ISO / IEC 14496-10|ITU-T (International Telecommunication Union-Telecommunications Standardization Sector) H.264) is being defined (hereinafter r...
