摘要： Methods and apparatus are described for sampling image data (806) that includes foreground/background color information (815) and mapping the samples to pixel sub-components which form a pixel element of an LCD display so that each pixel sub-component has a different portion of the image mapped thereto. The methods can be used with conventional color LCD displays that include pixels consisting of three non-overlapping red, green and blue rectangular pixel sub-elements or sub-components. The separately-controllable nature of individual RGB pixel sub-components is used to effectively increase a screen's resolution in the dimension perpendicular to the dimension in which the screen is striped. A scan conversion (914) process maps samples of the image data (806) to individual pixel sub-components, resulting in each of the pixel sub-components representing a different portion of the image. The color values are independently generated for each of the red, green, and blue pixel sub-components based on different portions of the image, rather than the color values for the entire pixel being generated based on a single sample or the same portion of the image.

摘要： Methods and apparatus for utilizing pixel sub-components which form a pixel element of an LCD display, e.g., as separate luminous intensity elements, are described. Each pixel of a color LCD display is comprised of three non-overlapping red, green and blue rectangular pixel sub-elements or sub-components. The invention takes advantage of the ability to control individual RGB pixel sub-elements to effectively increase a screen's resolution in the dimension perpendicular to the dimension in which the screen is striped, e.g., the RGB pixel sub-elements are arranged lengthwise. In order to utilize the effective resolution which can be obtained by treating RGB pixel sub-components separately, scaling (910) or super sampling of digital representations of fonts (806) is performed in one dimension at a rate that is greater than the scaling or sampling performed in the other dimension. In some embodiments where weighting is used in determining RGB pixel values, e.g., during scan conversion (914), the super sampling is a function of the weighting. During a scan conversion operation (914), RGB pixel sub-component values are independently determined from different portions of a scaled image. The scan conversion process (914) may involve use of different weights for each color component. Processing (915) to compensate for color distortions, e.g., color fringing, introduced by treating each pixel sub-component as an independent element is described. For horizontally flowing text applications, screens with vertical as opposed to horizontal striping are preferred.

摘要： Methods and apparatus are disclosed for sampling image data (1400) and mapping the samples (R, G, B of Cl) to pixel sub-components which form a pixel element (R1-R6) of an LCD display (1402) so that each pixel sub-component has a different portion of the image (1400) mapped thereto and at least one of the pixel sub-components has two or more samples mapped thereto. The methods can be used with conventional color LCD displays that include pixels consisting of three non-overlapping red, green and blue rectangular pixel sub-elements or sub-components. The separately-controllable nature of individual RGB pixel sub-components is used to effectively increase a screen's resolution in one dimension. A scan conversion process maps samples (R, G, B of Cl) of the image data (1400) to individual pixel sub-components, including mapping two or more samples to at least one of the pixel sub-components. As a result, each of the pixel sub-components represents a different portion of the image (1400). The color values are independently generated for each of the red, green, and blue pixel sub-components based on different portions of the image, rather than the color values for the entire pixel being generated based on a single sample or the same portion of the image (1400).

摘要： Methods and apparatus for sampling image data (620) and mapping the samples (622, 623, 624) to pixel sub-components (632, 633, 634) which form a pixel element of an LCD display so that each pixel sub-component (632, 633, 634) has a different portion of the image (620) mapped thereto. The methods can be used with conventional color LCD displays that include pixels consisting of three non-overlapping red, green and blue rectangular pixel sub-elements or sub-components. The pixel sub-components (632, 633, 634) can be arranged on the display device to form horizontal or vertical stripes of individual colors. The separately-controllable nature of individual RGB pixel sub-components is used to effectively increase a screen's resolution in the dimension perpendicular to the dimension in which the screen is striped. A scan conversion process maps samples (622, 623, 624) of the image data (620) to individual pixel sub-components, resulting in each of the pixel sub-components representing a different portion of the image. The color values are independently generated for each of the red, green, and blue pixel sub-components based on different portions of the image (620), rather than the color values for the entire pixel being generated based on a single sample or the same portion of the image.

摘要： Display apparatus, and methods for displaying images, e.g., text, on gray scale and color monitors (2400) are described. Gray scale displays implemented in accordance with the present invention include displays having a resolution in a first dimension, e.g., the horizontal dimension, which is several times the resolution in a second dimension, e.g., the vertical dimension. Various other displays (2400) of the present invention are capable of operating as both gray scale and color display devices. In one such display, the color filter used to implement a color portion of the display is omitted from another, e.g., gray scale portion of the same display. In such an embodiment, text, e.g., captions, are displayed using the gray scale portion of the display while color images, e.g., graphics, are displayed on the color portion of the display. In another display of the present invention, a color filter (2401) with filter cells (2410, 2411, 2412) that can be switched between a color and a clear mode of operation are employed. When images, e.g., text, are to be displayed as gray scale images, the filter cells (2410, 2411, 2412), corresponding to the portion of the display (2400) to be used to display the gray scale images, are switched to the clear mode of operation. In such an embodiment, the remaining portion or portions of the display (2400) may be used to display color images.
