Abstract
The present disclosure relates to an image processing apparatus, a method, and a program that can reduce delay that may possibly occur in intra prediction. An encoding apparatus excludes, when a CU split structure for luminance and a CU split structure for chroma are to be determined, for the CU split structure for chroma, a CU split structure that indicates a minimum size in at least one of a vertical direction or a horizontal direction to determine a CU split structure for the chroma, and encodes an image with the CU split structure for luminance and the CU split structure for chroma to generate an encoded stream. The present disclosure can be applied, for example, to an image processing apparatus.

An image processing apparatus comprising:
- a control section configured to exclude, when a CU split structure for luminance and a CU split structure for chroma are to be determined, for the chroma, a CU split structure that is a minimum size in at least one of a vertical direction or a horizontal direction to determine a CU split structure for the chroma;
- and
- an encoding section configured to encode an image with the CU split structure for luminance and the CU split structure for chroma to generate an encoded stream.
An image processing method performed by an image processing apparatus, comprising:
- excluding, when a CU split structure for luminance and a CU split structure for chroma are to be determined, for the chroma, a CU split structure that is a minimum size in at least one of a vertical direction or a horizontal direction to determine a CU split structure for the chroma;
- and
- encoding an image with the CU split structure for luminance and the CU split structure for chroma to generate an encoded stream.
A program for causing a computer to function as:
- a control section configured to exclude, when a CU split structure for luminance and a CU split structure for chroma are to be determined, for the chroma, a CU split structure that is a minimum size in at least one of a vertical direction or a horizontal direction to determine a CU split structure for the chroma;
- and
