3D VIDEO ENCODING AND DECODING METHODS AND APPARATUS

摘要

Methods and apparatus relating to encoding and decoding stereoscopic (3D) image data, e.g., left and right eye images, are described. Various pre-encoding and post-decoding operations are described in conjunction with difference based encoding and decoding techniques. In some embodiments left and right eye image data is subject to scaling, transform operation(s) and cropping prior to encoding. In addition, in some embodiments decoded left and right eye image data is subject to scaling, transform operations(s) and filling operations prior to being output to a display device. Transform information and/or scaling information may be included in a bitstream communicating encoded left and right eye images. The amount of scaling can be the same for an entire scene and/or program.

主权项

1. A method of processing stereoscopic image data including a left eye image and a right eye image of a frame pair, comprising:
scaling said left eye image and said right eye image by a first amount to generate a scaled left eye image and a scaled right eye image; performing a left eye transform on said scaled left eye image, said left eye transform including at least a cropping operation and generating a cropped left eye image; and performing a right eye transform on said scaled right eye image, said right eye transform including at least a cropping operation and generating a cropped right eye image.
