摘要： Methods and apparatus for implementing user controlled zoom operations during a stereoscopic, e.g., 3D, presentation are described. While viewing a 3D presentation of a scene environment, a user may switch to a zoom mode allowing the user to zoom in on a particular portion of the environment being displayed. In order to maintain the effect of being physically present at the event, and also to reduce the risk of making the user sick from sudden non-real world like changes in views of the environment, the user in response to initiating a zoom mode of operation is presented with a view which is the same or similar to that which might be expected as the result of looking through a pair of binoculars. In some embodiments the restriction in view is achieved by applying masks to enlarged version of left and right eye views to be displayed.

摘要： Methods and apparatus for using a display in a manner which results in a user perceiving a higher resolution than would be perceived if a user viewed the display from a head on position are described. In some embodiments one or more displays are mounted at an angle, e.g., sometimes in range a range from an angle above 0 degrees to 45 relative to a user's face and thus eyes. The user sees more pixels, e.g., dots corresponding to light emitting elements, per square inch of eye area than the user would see if the user were viewing the display head on due to the angle at which the display or displays are mounted. The methods and display mounting arrangement are well suited for use in head mounted displays, e.g., Virtual Reality (VR) displays for stereoscopic viewing (e.g., 3D) and/or non-stereoscopic viewing of displayed images.

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.

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： 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 determining location of objects surrounding a user of a 3D rendering and display system and indicating the objects to the user while the user views a simulated environment, e.g., on a headmounted display, are described. A sensor, e.g. camera, captures images or senses the physical environment where the user of the system is located. One or more objects in the physical environment are identified, e.g., by recognizing predetermined symbols on the objects and based on stored information indicating a mapping between different symbols and objects. The location of the objects relative to the user's location in the physical environment is determined. A simulated environment, including content corresponding to a scene and visual representations of the one or more objects, is displayed. In some embodiments visual representation are displayed in the simulated environment at locations determined based on the location of the objects relative to the user.

摘要： Camera and/or lens calibration information is generated as part of a calibration process in video systems including 3-dimensional (3D) immersive content systems. The calibration information can be used to correct for distortions associated with the source camera and/or lens. A calibration profile can include information sufficient to allow the system to correct for camera and/or lens distortion/variation. This can be accomplished by capturing a calibration image of a physical 3D object corresponding to the simulated 3D environment, and creating the calibration profile by processing the calibration image. The calibration profile can then be used to project the source content directly into the 3D viewing space while also accounting for distortion/variation, and without first translating into an intermediate space (e.g., a rectilinear space) to account for lens distortion.

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.
