Abstract:
In a computer system associated with a display device for displaying an image, the display device having a plurality of pixels, each including a plurality of pixel sub-components each of a different color, a method of reducing color artifacts in a displayed image that can be present as a result of treating the pixel sub-components as independent luminous intensity sources, the method comprising the steps for:obtaining image data that includes luminous intensity values associated with individual pixel sub-components of a pixel, the luminous intensity values representing different portions of the image that have been mapped to the individual pixel sub-components, the luminous intensity values including a red luminous intensity value associated with a red pixel sub-component of the pixel and a green luminous intensity value associated with a green pixel sub-component of the pixel; andadjusting the image data so that a difference between the red luminous intensity value and the green luminous intensity value is reduced based on a determination that color artifacts would otherwise be present in a displayed image rendered using the image data.
