Claim 7:
8. A device for flare estimation comprising:
a processor configured to:
determine a stitch line between a first image and a second image;
obtain a Y luminance flare estimate for points along the stitch line;
obtain a chrominance flare estimate for the points along the stitch line from the Y luminance flare estimate using a function that, for a point of the stitch line, uses a respective ratio of a chrominance value related to the point of the stitch line and a luminance value related to the point of the stitch line;
obtain a color space flare estimate from the Y luminance flare estimate and the chrominance flare estimate, wherein the color space flare estimate is obtained for a color space that is different from a YUV color space; and
correct at least one of the first image or the second image using the color space flare estimate.
