Abstract
Abstract A computer program product for detecting eye color defects of a subject in an image due to flash illumination comprises : a computer readable storage medium having a computer program stored thereon for performing the steps of detecting skin colored regions in a digital image; searching the skin colored regions for groups of pixels with color characteristic of redeye defect; and correcting color of the pixels based on a location of redeye defect found in step (b). <IMAGE>

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A method for detecting eye color defects of a subject in an
image due to flash illumination, the method comprising the steps of: (a) detecting a skin colored region in a digital image; (b) determining if the skin colored region has a predetermined
characteristic of a human face; (c) detecting a pair of candidate redeye defects in or adjacent to the
human face based on comparing a characteristic of the candidate redeye defects to
a characteristic of the detected human face; and (d) selecting the candidate redeye defects as actual redeye defects
based on the results of step (c).
Claim 2
Dependent Claim
34 words
The method as in claim 1, wherein step (c) includes detecting
the pair of redeye defects based on a comparison of a distance between the
candidate defects and a dimension of the human face.
Claim 3
Dependent Claim
24 words
The method as in claim 2, wherein step (c) includes providing a
width of the human face as the dimension of the human face.
Claim 4
Independent Claim
49 words
A method for detecting eye color defects of a subject in an
image due to flash illumination, the method comprising the steps of (a) detecting a pair of redeye defects based on a characteristic of
each defect in the pair in relation to a distance between the redeye defects.
Claim 5
Independent Claim
106 words
A method for detecting and correcting eye color defects of a
subject in an image due to flash illumination, the method comprising the steps of: (a) detecting a skin colored region in a digital image; (b) determining if the skin colored region has a predetermined
characteristic of a human face; (c) detecting a pair of candidate redeye defects in or adjacent to the
human face based on comparing a characteristic of the candidate redeye defects to
a characteristic of the detected human face; (d) selecting the candidate redeye defects as actual redeye defects
based on the results of step (c); and (e) correcting the redeye defects.
Claim 6
Dependent Claim
34 words
The method as in claim 5, wherein step (c) includes detecting
the pair of redeye defects based on a comparison of a distance between the
candidate defects and a dimension of the human face.
Claim 7
Dependent Claim
24 words
The method as in claim 6, wherein step (c) includes providing a
width of the human face as the dimension of the human face.
Claim 8
Independent Claim
58 words
A method for detecting and correcting eye color defects of a
subject in an image due to flash illumination, the method comprising the steps of: (a) detecting a pair of redeye defects based on a characteristic of
each defect in the pair in relation to orientation of the defect pair; and (b) correcting the pair of redeye defects.
Claim 9
Dependent Claim
20 words
The method as in claim 8, wherein step (a) includes providing a
match to an eye template as the characteristic.
Claim 10
Dependent Claim
25 words
The method as in claim 8 further comprising determining
whether the pair of defects are in a landscape or portrait orientation based on the
orientation.
