Image encoding and display
First Claim
1. An image encoding method comprising:
- for each of a left and a right image of a stereo pair of images, identifying, in an input image, a region of interest;
generating, by one or more processors, at least two image representations of that input image, such that one of the image representations is a high field of view (FOV) image representation including substantially all of the input image, and another of the image representations is a low FOV image representation having a lower FOV than the high FOV image representation and including at least the region of interest;
in which a relationship between pixel resolution and image size for the high FOV image representation and the low FOV image representation is such that, in relation to the region of interest, the low FOV image representation provides a higher amount of image detail than the high FOV image representation;
generating, by the one or more processors, one or more multiplexed images by juxtaposing at least portions of the left and right, high FOV and low FOV image representations, so as to include all image content of the left and right, high FOV and low FOV image representations in fewer than four multiplexed images; and
performing one or both of transmitting or storing the multiplexed images;
in which generating the one or more multiplexed images comprises generating a first multiplexed image by juxtaposing a whole of a first one of the left and right, high FOV and low FOV image representations next to a whole of a second one of the left and right, high FOV and low FOV image representations, and generating a second multiplexed image by juxtaposing a whole of a third one of the left and right, high FOV and low FOV image representations next to a whole of a fourth one of the left and right, high FOV and low FOV image representations.

Abstract
An image encoding method includes, for each of left and right images of an image stereo pair, identifying a region of interest (ROI) in an input image, generating multiple representations of that input image such that one representation is a high field of view (FOV) representation including substantially all of the input image and another representation is a low FOV representation having a lower FOV than the high FOV representation and including at least the ROI. The relationship between pixel resolution and image size for the high and low FOV representations is such that, in relation to the ROI, the low FOV representation provides more image detail than the high FOV representation. The method also includes generating one or more multiplexed images by juxtaposing portions of the left and right, high and low FOV representations so as to include all image content thereof in fewer than four multiplexed images.
