A method for correcting color in a system for creating a panoramic image from a plurality of images taken by a camera. The method comprising the steps of: receiving a color channel from at least a first image and a second image; creating an overlap portion between the first image and second image; and adjusting the color channel for the first image and for the second image in at least the overlap portion between the first image and the second image which is independent of motion estimation.In an alternate embodiment, a system and computer readable medium corresponding to the above method is described.

1. A device for correcting color in a system for creating a panoramic image from a plurality of images taken by a camera, the device comprising:an Input for receiving a color channel from at least a first image and a second image: an overlap portion between the first image and second image; means for adjusting the color channel for the first image and for the second image in at least the overlap portion between the first image and the second image which is independent of motion estimation, wherein the means for adjusting color comprises: means for computing the brightness (B1) and contrast (C1) for the first color channel; means for computing the brightness (B2) and contrast (C2) for the second color channel; means for adjusting color correction in at least the overlap portion between the first image and the second image; wherein the color channel for the first image is set equal to: I1=B1+C1.times.I1: and wherein the color channel for the second image is set equal to I2=B2+C2.times.I2; means for computing a histogram of color distribution for the first color channel (H1); means for computing a histogram of color distribution for the second color channel (H2); and wherein B1 and B2 are set equal to: H2-(matched contrast (C)).times.H1; and wherein the C is set equal to the square root of a variance calculated for H1 divided by a variance calculated for H2.
