Abstract:
In a computer system including a processing unit and a display device for displaying an image, the display device having a plurality of pixels, each including a plurality of pixel sub-components, a method of generating a bitmap from image data that geometrically represents the image in preparation for displaying the image on the display device, the method comprising the steps of:mapping a first set of one or more samples of the image data that geometrically represents the image to a first pixel sub-component of a first pixel of the plurality of pixels so as to generate a first portion of the bitmap that corresponds to the first pixel sub-component of the first pixel;mapping a second set of one or more samples of the image data to a second pixel sub-component of the first pixel so as to generate a second portion of the bitmap that corresponds to the second pixel sub-component of the first pixel;mapping a third set of one or more samples of the image data to a third pixel sub-component of the first pixel so as to generate a third portion of the bitmap that corresponds to the third pixel sub-component of the first pixel, the first, second, and third sets of one or more samples being sampled from spatially different and non-overlapping regions of the image data; andgenerating first, second, and third independent luminous intensity values that correspond, respectively, to the first, second, and third pixel sub-components and are based, respectively, on the first, second, and third sets of one or more samples.
