摘要

A high resolution 3D image may be encoded into a first multiplexed image frame and a second multiplexed image frame in a base layer (BL) video signal and an enhancement layer (EL) video signal. The first multiplexed image frame may comprise horizontal high resolution image data for both eyes, while the second multiplexed image frame may comprise vertical high resolution image data for both eyes. Encoded symmetric-resolution image data for the 3D image may be distributed to a wide variety of devices for 3D image processing and rendering. A recipient device may reconstruct reduced resolution 3D image from one of the first multiplexed image frame or the second multiplexed image frame. A recipient device may also reconstruct high resolution 3D image by combining high resolution image data from both of the first multiplexed image frame and the second multiplexed image frame.

說明書

In some embodiments, instead of using a demultiplexer (160-2) as illustrated in FIG. 3A to derive full resolution LE image frame (e.g., 162-L), a demultiplexer (160-3) as illustrated in FIG. 3B may be used. In FIG. 3B, an up-sampler (206-V) in the demultiplexer (160-3) may be configured to up-sample the second LE portion (204-L) in the vertical direction to create a LE image frame (208-V) that comprises high spatial frequency content in the horizontal direction.

A high pass filter (210-2) that preserves high spatial frequency content in the vertical direction may be applied to the first LE portion (202-L) to yield a high pass LE portion. An up-sampler 206-H in the demultiplexer (160-3) may be configured to up-sample the high pass LE portion in the horizontal direction to create a high pass LE image frame (212-2) that comprises high spatial frequency content in the vertical direction.

An adder (222) in the demultiplexer (160-3) may be configured to accept the high pass LE image frame (212-2) and the LE image frame (208-V) as input and to apply an adding operation on the high pass LE image frame (212-2) and the LE image frame (208-V) to generate the full resolution LE image frame (162-L) that comprises high spatial frequency content in both vertical and horizontal directions.
