METHODS AND APPARATUS FOR GENERATING AND USING REDUCED RESOLUTION IMAGES AND/OR COMMUNICATING SUCH IMAGES TO A PLAYBACK OR CONTENT DISTRIBUTION DEVICE
First Claim
1. A method comprising the steps of:
- selecting a first resolution allocation to be used for at least one image corresponding to a first portion of an environment;
performing a resolution reduction operation on a first image of said first portion of the environment in accordance with the selected first resolution allocation to generate a first reduced resolution image; and
communicating said first reduced resolution image to a playback device.

Abstract
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.

19. A non-transitory computer readable medium comprising processor executable instructions, which when executed by a processor, control a system to:
-
select a first resolution allocation to be used for at least one image corresponding to a first portion of an environment; perform a resolution reduction operation on a first image of said first portion of the environment in accordance with the selected first resolution allocation to generate a first reduced resolution image; and communicate said first reduced resolution image to a playback device.
