Color balance in digital photography |
摘要 |
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. |

1. In a digital photographic system having a camera unit and a processor complex, a method for generating an output image from a first image and a second image, the method comprising:
calculating a first intensity for a first pixel associated with the first image and a second intensity for a second pixel associated with the second image; calculating a blend value based on the first intensity, the second intensity, and a blend surface function; and generating a blended pixel associated with the output image by blending the first pixel with the second pixel based on the blend value, wherein the blend surface function comprises a first region, a second region, and a intervening discontinuity. |
