Claim Text:
1. A depth camera device comprising: a depth camera that captures depth image data having a bit depth of N-bits; one or more processors; one or more computer-readable storage media storing computer-executable instructions of an encoder module executed by one or more processors to: partition the depth image data into an M-bit most significant bit (MSB) layer and an L-bit least significant bit (LSB) layer, the M-bit MSB layer including a M most significant bits of the depth image data and the L-bit LSB layer including a N-M least significant bits of the depth image data; quantize the MSB layer; generate quantization difference data based at least in part on the MSB layer and the quantized MSB layer; and apply the quantization difference data to the LSB layer to generate an adjusted LSB layer.
