Abstract
A method, medium, and apparatus processing depth information of a depth image. The apparatus adaptively presenting information on depth information includes a section determination unit determining which one of plural sections respective depth values for pixels of the 3D image fall within, with the plural sections being defined by a measured limit distance for the 3D image being parsed into the plural sections based on distance based depth resolution information, and an adaptive quantization unit to selectively quantize and represent each depth value based on a respective predefined quantization setting of the one section.

An apparatus adaptively representing information of depth information of a 3D image, the apparatus comprising:
- a processor to control each of the following units;
- a distance section division processing unit to receive the 3D image including a depth value ranging from 0 to a measured limit distance which is a fixed value for specification of camera capturing the 3D image, and divide the measured limit distance into plural sections, wherein the section is an interval having a fixed/uniform step size;
- a section determination unit to determine which one of plural sections depth values for pixels of the 3D image fall within;
- and
- an adaptive quantization unit to generate section information indicating the determined section, and quantize the depth value based on the fixed/uniform step size of the determined section,
- wherein section information is represented by a fixed number of bits, wherein a step size for the section near 0 is smaller than a step size for the section near the measured limit distance.
A method of representing adaptive information of depth information of a 3D image, the method comprising:
