Abstract:
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 input data to determine a region of interest of the preview image; and automatically performing a local tone map operation on the region of interest of the preview image by adjusting the tone curve based on one or more local statistics determined from the region of interest to yield a low dynamic range image, wherein adjusting the tone curve increases a visibility of substantially all details in the region of interest in the low dynamic range image and decreases global contrast of the low dynamic range image to make details only outside of the region of interest less visible than in the preview image.
