Abstract

The present technology relates to an image processing apparatus and method that are capable of enhancing encoding efficiency while suppressing a decrease in the efficiency of encoding processing. The image processing apparatus includes an encoding mode setter that sets, in units of coding units having a hierarchical structure, whether a non-compression mode is to be selected as an encoding mode for encoding image data, the non-compression mode being an encoding mode in which the image data is output as encoded data, and an encoder that encodes the image data in units of the coding units in accordance with a mode set by the encoding mode setter. The present disclosure can be applied to, for example, an image processing apparatus.

Description

TECHNICAL FIELD

[0001] The present disclosure relates to an image processing apparatus and method, and particularly relates to an image processing apparatus and method that enable enhancement of encoding efficiency while suppressing a decrease in the efficiency of encoding processing.BACKGROUND ART

[0002] In recent years, apparatuses compliant with a compression format such as MPEG (Moving Picture Experts Group), in which image information is digitally handled and is compressed using an orthogonal transform such as the discrete cosine transform and by motion compensation by utilizing a redundancy particular to image information for the purpose of achieving highly efficient transmission and accumulation of information, have been becoming prevalent for use in both distribution of information from broadcast stations and reception of information in general households.

[0003] In particular, MPEG-2 (ISO (International Organization for Standardization) / IEC (international Electrotechnical Commiss...
