Image processing device and method

Abstract

The present invention relates to an image processing device and method configured so as to be capable of improving coding efficiency. The image processing device and method comprise: a weight mode determination unit that determines for each prescribed area a weight mode, which is a mode for weighted prediction performed while weighting, using a weight coefficient, inter motion prediction compensation processing for encoding of an image; a weight mode information generation unit that generates for each said area weight mode information indicating the weight mode determined by the weight mode determination unit; and an encoding unit that encodes the weight mode information generated by the weight mode information generation unit. This disclosure can be applied to image processing devices.

Description

technical field [0001] The present disclosure relates to an image processing device and method, and more particularly, to an image processing device and method capable of improving coding efficiency. Background technique [0002] In recent years, image information has been handled as numbers. In this case, for the purpose of efficiently transmitting and accumulating information, based on the Means such as the MPEG (Moving Picture Experts Group) method of compression for motion compensation can be widely used not only for information distribution such as broadcasting stations but also for information reception at ordinary households. [0003] Specifically, MPEG2 (ISO (International Organization for Standardization) / IEC (International Electrotechnical Commission) 13818-2) is defined as a general-purpose image coding method, and utilizes overlaid interlaced scan images and sequential scan images as well as standard-resolution images and high-definition images The standard of M...

Problems solved by technology

[0012] Incidentally, in MPEG2 and MPEG4, for example, motion such as fading scenes exists, but in sequences where luminance changes, encoding tools are not prepared to absorb changes in luminance, and therefore, there is a problem that encoding efficiency decreases
