Abstract

Official abstract text for this publication.

Technologies may provide for yielding a low dynamic range image. A logic architecture may be implemented to perform a global tone map operation on a high dynamic range image to yield a preview image. The logic architecture may also be implemented to perform a local tone map operation on a region of interest of a preview image to yield a low dynamic range image. Additionally, the logic architecture may be implemented to provide an image that includes a predetermined amount of image pixels that are not saturated. In addition, the logic architecture may be implemented to employ image view data to yield a low dynamic range image. Moreover, the logic architecture may be implemented to convert the region of interest into a region that includes the foveal region of a user. In one example, the tone map operation is performed entirely automatically and interactively.

First claim

Opening claim text (preview).

We claim: 1. A method comprising: receiving a high dynamic range image; performing a global tone map operation on the high dynamic range image by adjusting a tone curve associated with the high dynamic range image based on one or more global statistics determined from the high dynamic range image to yield a preview image, wherein adjusting the tone curve increases a visibility of substantially all details in both light and dark regions in the preview image; employing user inpu…
