Abstract
A method for producing a composite digital image, includes the steps of: providing a plurality of partially overlapping source digital images having pixel values that are linearly or logarithmically related to scene intensity; 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 combining the adjusted source digital images to form a composite digital image

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.
