Problems solved by technology

[0008] However, recently, there has been a demand for high-compression rate encoding (for example, a need to compress an image of approximately 4000×2000 pixels four times that of a high-definition image or a need for distribution of a high-definition image in a limited transmission rate environment such as the Internet ) further increases

Abstract

The present invention relates to an image processing apparatus and method that enable minimizing degradation of image quality. It is set: a threshold value setting unit, which sets a threshold value according to the bit depth of the image data, the threshold value is used to identify the characteristics of the neighboring pixels of the current block in the intra prediction process performed when the image data is encoded; and the filter processing unit, by Filtering processing is performed on the adjacent pixels using a filter corresponding to the characteristics of the adjacent pixels identified by the threshold set using the threshold setting unit. The present invention can be applied to, for example, an image processing device.

Description

technical field [0001] The present disclosure relates to an image processing device and an image processing method, and more particularly, to an image processing device and an image processing method capable of suppressing image quality degradation. Background technique [0002] In recent years, devices for compressing and encoding images by employing an encoding scheme in which image information is regarded as digital data, and at this time, for efficient information transfer and accumulation, by Compression is performed by orthogonal transform such as discrete cosine transform and motion compensation using redundancy unique to image information. The encoding scheme includes, for example, MPEG (Moving Picture Experts Group) and the like. [0003] Specifically, the MPEG-2 (ISO / IEC 13818-2) scheme is defined as a general-purpose image coding scheme, and is a standard covering interleaved scanning images and sequential scanning images as well as standard-resolution images and...
