Process and system for encoding and playback of stereoscopic video sequences
A method for decoding a compressed image stream, the image stream having a plurality of frames, each frame consisting of a merged image including pixels from a left image and pixels from a right image. The method involves the steps of receiving each merged image; changing a clock domain from the original input signal to an internal domain; for each merged image, placing at least two adjacent pixels into an input buffer and interpolating an intermediate pixel, for forming a reconstructed left frame and a reconstructed right frame according to provenance of the adjacent pixels; and reconstructing a stereoscopic image stream from the left and right image frames. The invention also teaches a system for decoding a compressed image stream.
STEREOSCOPIC VIDEO ENCODING AND DECODING METHODS AND APPARATUS
Methods and apparatus for stereoscopic image encoding and decoding are described. Left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.

A wearable apparatus may include an image display; a content receiver; and a processor configured to process image data received through the content receiver to generate an image frame, and control the image display to display the image frame. The processor may be configured to compare a vertical pixel line of a left edge portion of the image frame with a vertical pixel line of a right edge portion of the image frame, and when it is determined that the image frame is a 360-degree Virtual Reality (VR) image, process the 360-degree VR image.
