CORRECTING ARTIFACTS ON A DISPLAY
First Claim
Patent Images
1. A method comprising:
- identifying a first artifact in an image on a display, the first artifact caused by a first subpixel of a first pixel;
determining a type of the first artifact based on a location of the first artifact relative to content of the image, wherein determining the type of the first artifact comprises determining the type of the first artifact is a single artifact when the location of the first artifact is greater than a threshold distance from a second artifact, the second artifact caused by a first subpixel of a second pixel; and
correcting the first artifact to remove the appearance of the first artifact from the display based on the type of the first artifact, wherein correcting the first artifact to remove the appearance of the first artifact comprises correcting, when the type of the first artifact is a singlet artifact the first artifact using a singlet correction that adjusts an intensity of a neighboring subpixel adjacent the first subpixel of the first pixel proportional to an intensity of a second subpixel of the first pixel when the first.

Abstract
An example involves identifying a first artifact in an image on a display, the first artifact caused by a first subpixel of a first pixel, determining a type of the first artifact based on a location of the first artifact relative to content of the image, and correcting the first artifact to remove the appearance of the first artifact from the display based on the type of the first artifact.

9. An apparatus comprising:
-
an artifact identifier to identify artifacts in an image presented on the display, the artifacts caused by artifact pixels, wherein the artifact identifier to identify the artifacts in the image comprises the artifact classifier to; identify potential artifact pixels corresponding to the artifacts; determine that intensities of the potential artifact pixels satisfies a threshold; and identify the artifact pixels as artifacts when the potential artifact pixels are in a dark neighborhood of the image; an artifact classifier to classify the artifacts in the image as singlet artifacts, doublet artifacts, or triplet artifacts based on locations of the artifact pixels; and an artifact corrector to correct the artifacts to remove the artifacts from the display based on whether the artifacts are singlet artifacts, doublet artifacts, or triplet artifacts. - View Dependent Claims (11, 12, 13)

14. A non-transitory machine readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
identify a subpixel of as pixel causing an artifact in a display; determine the type of artifact caused by the subpixel based at least in part on whether the artifact is diagonally adjacent other artifacts; and correct the artifact to remove the appearance of the artifact based on the type of the artifact by adjusting an intensity of a subpixel of a neighboring pixel adjacent the subpixel. - View Dependent Claims (15, 16, 17, 18)
