Abstract:
In a computer system including a processing unit and a display device for displaying an image, the display device having a plurality of pixel sub-components each of which has one of three different colors, a method for improving resolution of the displayed image comprising the steps for:storing, at the computer system, information defining an outline of the image and a foreground color and a background color associated with the image;mapping samples of the information to individual pixel sub-components as opposed to mapping samples to an entire pixel, each of the pixel sub-components having mapped thereto to a spatially different set of one or more of the samples;determining whether each set of one or more samples mapped to a particular pixel sub-component corresponds to a foreground color or a background color of the image;generating a separate luminous intensity value for each pixel sub-component as opposed to each full pixel, the separate luminous intensity value for each sub-component being based on the set of one or more samples mapped thereto, and also being based on the determination of foreground color or background color for each set of one or more samples; anddisplaying the image on the display device by applying the separate luminous intensity values to each sub-component rather than to entire pixels, resulting in each of the pixel sub-components, rather than entire pixels, representing the displayed image.
