Anti-aliasing system and method
View Patent ↗A method of displaying a character. A representation of a character is determined in a bit map having a number of bits greater than a number of pixels in a region of a display in which the character is to be displayed. Based on a relative number of bits that are on in respective portions of the bit map, luminances for corresponding pixels are determined. The character is displayed in the region having the particular number of pixels, and the pixels are displayed with the determined luminances. A system for displaying a character is disclosed, in which the character is to be displayed within a region of a display having a particular number of pixels. According to various embodiments of the invention, the display comprises a television, a color television, a display of a hand held device, a billboard, or other display device. A method for displaying a shape is described. A method of displaying a shape is disclosed. A television system and a computer program product are disclosed. According to one embodiment of the invention, logic, based on a relative number of bits that are on in respective portions of the bit map, determines an attribute for corresponding pixels. The attribute may comprise luminance, saturation, hue, or other attribute.
1. A method of displaying a set of characters, the method comprising:
in a system having a specific hardware display device that has a specific resolution, receiving a command to generate a character from the set of characters;
if the character has already been processed and is available in a cache, displaying the character;
if the character has not already been processed, taking the resolution of the hardware display device into consideration, determining a representation of a character in a bit map having a number of bits greater than a number of pixels in a region of the display device in which the character is to be displayed wherein
various bits in a respective portion of the bit map corresponding to a pixel; and
among the various bits that correspond to the pixel, different bits correspond to different locations on the character;
based on a percentage of bits that are on in respective portions of the bit map, determining luminance for corresponding pixels; and
displaying the character in the region having the particular number of pixels, the pixels being displayed with the determined luminance.
