There is provided an image processing device and a method that enables the number of attributes corresponding to a single geometry to be variable in a time direction. An attribute video frame that is a video frame in which a patch obtained by projecting each of a plurality of attributes to a two-dimensional plane for each partial region is arranged is generated, the plurality of attributes corresponding to a single geometry of a point cloud that expresses an object with a three-dimensional shape as a group of points, the generated attribute video frame for each attribute is coded, and attribute information that is information indicating the generated attribute video frames corresponding to the same timing is generated. The present disclosure can be applied to, for example, an image processing device, electronic equipment, an image processing method, a program, or the like.

Image processing device and method

There is provided an image processing device and method capable of suppressing an increase in amount of code. For example, a patch generation parameter used in patch generation processing for generating a patch of an attribute serving as a processing target by referring to an attribute different from the attribute serving as the processing target is derived for some of a plurality of attributes corresponding to single geometry of a point cloud that expresses an object having a three-dimensional shape as a set of points, the derived patch generation parameter is encoded, and an attribute video frame in which a base patch representing a base attribute that is an attribute different from some of the plurality of attributes has been arranged is encoded. The present disclosure can be applied to, for example, an image processing device, an electronic device, an image processing method, or a program.
