摘要： A graphics integrated circuit chip is used in a set-top box for controlling a television display. The graphics chip processes analog video input, digital video input, graphics input and audio input simultaneously. A video scaling system preferably conserves memory by downscaling video prior to capturing the video in memory and upscaling video after the video is called out of memory.

摘要： Displaying image data with sub-pixel precision on display devices having pixels with separately controllable pixel sub-components, such as those used in liquid crystal display devices. Samples of the image data are obtained, and spatially different sets of one or more of the samples are mapped to individual pixel sub-components as opposed to mapping sets of samples to entire pixels. Luminous intensity values based on the mapped sets of samples are generated and used to control the operation of the separately controllable pixel sub-components. The image is thereby displayed on the display device, with different portions of the image being represented by different pixel sub-components, resulting an image with sub-pixel resolution. The image data can represent a text character, in which case the stem width of a stem of the text character can have a value that is not an integer multiple of the width of a full pixel.

摘要： When an original pixel corresponding to a target pixel is white, and when target pixel-forming three sub-pixels are black, then it is judged that the target pixel is blurred. At this time, a green sub-pixel having the greatest degree of a luminance contribution among the target pixel-forming three sub-pixels are rendered in white. As a result, blurring between object lines is inhibited.

摘要： A graphics display system integrated circuit is used in a set-top box for controlling a television display. The graphics display system processes analog video input, digital video input, and graphics input. The system incorporates a unified memory architecture that is shared by the graphics system, a CPU, and other peripherals. The unified memory architecture uses real time scheduling to service tasks. Critical instant analysis is used to find a schedule for memory usage that does not affect memory requirements of real time tasks while at the same time servicing non-real-time tasks as needed.

摘要： A bitmap of a shape, such as a font, can be subpixel optimized by producing for each of a display's subpixels a coverage value representing the percent of its area covered by the shape being represented and by distributing, to prevent color imbalance, an amount of a given subpixel's coverage value to nearby subpixels of different colors as a function of the percent of the given subpixel's coverage value that causes color imbalance. Web pages can be displayed with scaled-down and subpixel optimized images. A given layout of a Web page can be displayed at each of at least two different selected scale factors, with the font bitmaps used to represent characters in the display at each scale factor having their shape and pixel alignment selected to improve readability for the particular pixel size at which they are displayed at each such scale factor.

摘要： A method for creating anti-aliased characters on a computer output device includes the steps of generating a call from a client process for a character to be rendered, selecting a best alignment grid from a set of alignment grids associated with the device grid, rendering the character at a high resolution, and aligning stems of the character with an alignment grid corresponding to the resolution of an output device. The step of aligning the high resolution rendered stems to the alignment grid provides for an anti-aliased output with balanced stems.

摘要： Character data to be displayed is obtained. The obtained character data is boldfaced by increasing a character line width of the obtained character data in a first direction by an amount corresponding to at least a width of a light-emitting element. A boldfaced character is displayed on a display screen in accordance with data derived from the boldfaced character data. In boldfacing the character data, a character line width-increasing pattern is selected in accordance with a degree to which the luminous intensity of the light-emitting elements contributes. In particular, the step of increasing the character line width in order to boldface the character data avoids a pattern in which a B-light (blue) emitting element is located at a next-to-endmost inner position of the increased character line width. A light-emitting pattern is selected in order to eliminate an isolated sub-pixel spot, which otherwise would objectionably be visible in the boldfaced character.
摘要翻译：获得要显示的字符数据。通过将获得的字符数据的第一方向的字符行宽度增加至少与发光元件的宽度相对应的量来将获得的字符数据粗体化。根据从粗体字符数据导出的数据，在显示屏幕上显示粗体字符。在以粗体显示字符数据的情况下，根据发光元件的发光强度的贡献度选择字符线宽度增加图案。特别地，增加字符行宽度以粗体字符数据的步骤避免了B型（蓝色）发射元件位于增加的字符行宽度的下一个最内侧位置的图案。选择发光图案以消除孤立的子像素点，否则将在粗体字符中令人反感地看到。

摘要： When a sub-pixel of B having a small contribution to luminance emits light in isolation, a sub-pixel of R is caused to emit light or sub-pixels of B and R are caused to emit light. As a result, a sub-pixel of R having, a larger contribution to luminance than the sub-pixel of B, is caused to emit light. When an adjacent set of sub-pixels B and R having a small contribution to luminance emits light in isolation, a set of sub-pixels R and G is caused to emit light. As a result, a set of sub-pixels R and G having a higher degree of contribution to luminance than the set of sub-pixels B and R is caused to emit light. Therefore, contrast degradation from any allocation of light-emitting patterns to sub-pixels having poor luminance is eliminated and a high quality display is achieved.
