Abstract
Official abstract text for this publication.
A technique for generating a digital photograph comprises blending two related images, each sampled according to a different illumination environment. The two related images are blended according to a blend surface function that includes a height discontinuity separating two different blend weight regions. Color consistency between the two related images is achieved by spatial color correction prior to blending. The technique enables a digital camera to generate a strobe image having an appearance of consistent color despite discordant strobe and ambient scene illumination.
First claim
Opening claim text (preview).
We claim: 1. A computer program product embodied on a non-transitory computer readable medium, comprising: code for generating a color corrected pixel based on a first pixel of a first image, a second pixel of a second image, correction factors, and histogram factors; code for generating a blended pixel based on the first pixel, the color corrected pixel, and a blend surface; and code for storing the blended pixel within a blended image, wherein the computer program product…
