Method and system for compositing images with compensation for light falloff
First Claim
Patent Images
1. A method for producing a composite digital image, comprising the steps of:
- a) providing a plurality of partially overlapping source digital images having pixel values that are linearly or logarithmically related to scene intensity;
b) modifying the source digital images by applying to one or more of the source digital images a radial exposure transform to compensate for exposure fall off as a function of the distance of a pixel from the center of the digital image to produce adjusted source digital images; and
c) combining the adjusted source digital images to form a composite digital image.
