Correction of redeye defects in images of humans
First Claim
1. A method for correcting redeye in a digital image, said image having at least one redeye defect pair, said method comprising the steps of:
- measuring a defect pair separation;
adjusting the size of said defects of said defect pair responsive to said defect pair separation to provide adjusted defects; and
changing the color of said adjusted defects.

Abstract
In a method and system for correcting redeye in a digital image of a human, a defect pair separation is measured. The members of the defect pair are each redeye defects in the image. Each defect has one or more pixels. The defects are adjusted, that is, retained unchanged or reduced in size to provide adjusted defects. The adjustment can follow growth of initial seed defects. The adjustment is responsive to the defect pair separation and can include trimming of pixels beyond a size limit calculated using the defect pair separation. Following the adjustment, the color of the adjusted defects is changed to reduce redeye.

20. A method for correcting redeye in a digital image, said method comprising the steps of:
-
detecting a pair of seed defects in said image;
growing each of said seed defects to provide a pair of grown defects;
measuring the separation of the members of one of said pair of seed defects and said pair of grown defects to provide a defect pair separation;
adjusting the size of said grown defects responsive to said defect pair separation to provide adjusted defects; and
changing the color of said adjusted defects to reduce apparent redeye. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

35. A system for correcting redeye in a digital image, said image having at least one redeye defect pair, said system comprising:
-
a distance measurer measuring a defect pair separation;
a defect grower receiving said defect pair separation and adjusting the size of said defects responsive to said defect pair separation to provide adjusted defects; and
a color modifier changing the color of said adjusted defects. - View Dependent Claims (36, 37, 38, 39)

40. A method for correcting redeye in a digital image having a plurality of pixels, each said pixel having values of three color components, said color components including a least red component and two additional components, said least red component having a lesser red spectral sensitivity than said additional components, said method comprising the steps of:
-
locating a redeye defect in the image; and
setting said values of said color components of each said pixel of said adjusted defects to the value of the respective said least red component. - View Dependent Claims (41, 42, 43)

44. A method of correcting redeye defects in a digital image of a human subject, the method comprising:
-
locating redeye defects of the human subject;
determining an average flesh color associated with the human subject;
calculating a target pupil value from the average flesh color; and
using the target pupil value to modify color of the redeye defects.
