1. An apparatus adaptively representing information of depth information of a 3D image, the apparatus comprising: a section determination unit to determine 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.
