Method and apparatus for implementing a digital graduated filter for an imaging apparatus
First Claim
1. A method of capturing image of a high-dynamic range subject, the method including:
- capturing multiple images of the subject in an imaging device, each image comprising portions of highlights and portions of shadows;
combining the multiple images to form a final image, wherein the combining includes combining different number of the images to form highlights than the number of the images to form the shadows; and
storing the final image.

Abstract
A digital graduated filter is implemented in an imaging device by combining multiple images of the subject wherein the combining may include combining different numbers of images for highlights and for shadows of the subject. The imaging device may present a user with a set of pre-defined graduated filter configurations to choose from. A user may also specify the direction of graduation and strength of graduation in a viewfinder. In an alternative implementation, combining may include scaling of pixels being added instead of varying the number of images being combined. In an alternative implementation, the combining of multiple images may include combining a different number of images for highlights of the subject than for shadows of subject.
