Abstract
An image processing part includes an edge enhancing part, an artifact detecting part and a compensating part. The edge enhancing part emphasizes an edge portion of an object in input image data. The artifact detecting part detects a corner outlier artifact at an area adjacent to the edge portion of the object. The compensating part compensates the corner outlier artifact. Accordingly, the edge portion of the object may be enhanced and the corner outlier artifact is decreased so that the display quality may be improved.
Claims20
An image processing part comprising:
- an artifact detecting part detecting a corner outlier artifact at an area adjacent to an edge portion of an object in input image data;
- and
- a compensating part compensating the corner outlier artifact,
- wherein the artifact detecting part detects a pixel having a maximum grayscale difference between a pixel grayscale and an average grayscale of pixels in a matrix shape among the pixels in the matrix shape, and determines that the pixel having a maximum grayscale difference has the corner outlier artifact when each of differences between a grayscale of the pixel having a maximum grayscale difference and grayscales of other pixels in a matrix shape is greater than a low threshold value.
An image processing part comprising:
- an artifact detecting part detecting a corner outlier artifact at an area adjacent to an edge portion of an object in input image data;
- and
- a compensating part compensating the corner outlier artifact
- wherein the compensating part determines target pixels to be compensated, the target pixels including a pixel having the corner outlier artifact and at least two pixels sequentially disposed along a column direction from the pixel having the corner outlier artifact.
A display apparatus comprising:
- a display panel displaying an image;
- a gate driver providing a gate signal to the display panel;
- a data driver providing a data voltage to the display panel;
- and
- an artifact detecting part detecting a corner outlier artifact,
- wherein the artifact detecting part detects a pixel having a maximum grayscale difference between a pixel grayscale and an average grayscale of pixels in a matrix shape among the pixels in the matrix shape, and
- wherein the artifact detecting part determines that the pixel having a maximum grayscale difference has the corner outlier artifact when each of differences between a grayscale of the pixel having a maximum grayscale difference and grayscales of the other pixels in a matrix shape is greater than a low threshold value.
A method of processing an image, the method comprising:
- detecting a corner outlier artifact at an area adjacent to an edge portion of an object in input image data;
- and
- compensating the corner outlier artifact,
- wherein the detecting a corner outlier artifact comprises:
- detecting a pixel having a maximum grayscale difference between a pixel grayscale and an average grayscale of pixels in a matrix shape among the pixels in the matrix shape;
- and
- determining that the pixel having a maximum grayscale difference has the corner outlier artifact when each of differences between a grayscale of the pixel having a maximum grayscale difference and grayscales of the other pixels in a matrix shape is greater than a low threshold value.
