摘要： An unobstructed image portion of a captured image from a first camera of a camera pair, e.g., a stereoscopic camera pair including fisheye lenses, is combined with a scaled extracted image portion generated from a captured image from a second camera in the camera pair. An unobstructed image portion of a captured image from the second camera of the camera pair is combined with a scaled extracted image portion generated from a captured image from the first camera in the camera pair. As part of the combining obstructed image portions which were obstructed by part of the adjacent camera are replaced in some embodiments. In some embodiments, the obstructions are due to adjacent fisheye lens. In various embodiments fish eye lenses which have been cut to be flat on one side are used for the left and right cameras with the spacing between the optical axis approximating the spacing between the optical axis of a human person's eyes.

摘要： Methods and apparatus for using selective resolution reduction on images to be transmitted and/or used by a playback device are described. Prior to transmission one or more images of an environment are captured. Based on image content, motion detection and/or user input a resolution reduction operation is selected and performed. The reduced resolution image is communicated to a playback device along with information indicating a UV map corresponding to the selected resolution allocation that should be used by the playback device for rendering the communicated image. By changing the resolution allocation used and which UV map is used by the playback device different resolution allocations can be made with respect to different portions of the environment while allowing the number of pixels in transmitted images to remain constant. The playback device renders the individual images with the UV map corresponding to the resolution allocation used to generate the individual images.

摘要： Methods and apparatus for streaming or playing back stereoscopic content are described. Camera dependent correction information is communicated to a playback device and applied in the playback device to compensate for distortions introduced by the lenses of individual cameras. By performing lens dependent distortion compensation in the playback device edges which might be lost if correction were performed prior to encoding are preserved. Distortion correction information maybe in the form of UV map correction information. The correction information may indicate changes to be made to information in a UV map, e.g., at rendering time, to compensate for distortions specific to an individual camera. Different sets of correction information maybe communicated and used for different cameras of a stereoscopic pair which provide images that are rendered using the same UV map. The communicated correction information is sometimes called a correction mesh since it is used to correct mesh related information.

摘要： Methods and apparatus for collecting user feedback information from viewers of content are described. Feedback information is received from viewers of content. The feedback indicates, based on head tracking information in some embodiments, where users are looking in a simulated environment during different times of a content presentation, e.g., different frame times. The feedback information is used to prioritize different portions of an environment represented by the captured image content. Resolution allocation is performed based on the feedback information and the content re-encoded based on the resolution allocation. The resolution allocation may and normally does change as the priority of different portions of the environment change.

摘要： Methods and apparatus for packing images into a frame and/or including additional content and/or graphics are described. A composite image is generated including at least one image in addition to another image and/or additional image content. A playback device received an encoded frame including a captured image of a portion of and environment and the additional image content. The additional image content is combined with or used to replace a portion of the image of the environment during rendering. Alpha value mask information is communicated to the playback device to provide alpha values for use in image combining. Alpha values are communicated as pixel values in the encoded frame or as additional information. One or more mesh models and/or information on how to map image content to the one or more mesh models is communicated to the playback device for use in rendering image content recovered from a frame.
