摘要： Un procedimiento de mejora de la resolución de una imagen mostrada por un sistema (100, 520) de ordenador que incluye una unidad (521) de proceso y un dispositivo (102, 547) de visualización para mostrar la imagen, teniendo el dispositivo (102, 547) de visualización una pluralidad de píxeles, cada uno de los cuales incluye al menos tres subcomponentes (632, 633, 634) de píxel, cada uno de un color diferente, estando dispuestos los subcomponentes de píxel de la pluralidad de píxeles para formar bandas de subcomponentes de píxel del mismo color que discurren por toda la longitud del dispositivo de visualización en una misma dirección, comprendiendo el procedimiento las etapas de: modificar la escala (910) de la información que representa una imagen (1002, 1004) en la dirección perpendicular a las bandas en un factor mayor que en la dirección paralela a las bandas; correlacionar (914) muestras (622, 623, 624) de la información (1014, 1018) de escala modificada que representan la imagen con los subcomponentes individuales (632, 633, 634) de píxel, en contraposición con correlacionar las muestras con el píxel completo, habiendo correlacionado consigo cada uno de los subcomponentes (632, 633, 634) de píxel un conjunto diferente de una o más de las muestras (622, 623, 624) procedentes de porciones diferentes de la información de escala modificada; determinar un valor separado de intensidad lumínica para cada subcomponente (632, 633, 634) de píxel en base al conjunto diferente de una o más muestras correlacionadas con el mismo e independientemente de la determinación para los otros subcomponentes de píxel; y mostrar (916) la imagen en el dispositivo de visualización usando los valores separados de la intensidad lumínica, dando como resultado que cada uno de los subcomponentes (632, 633, 634) de píxel, no los píxeles enteros, represente una porción diferente de la imagen.

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 or super sampling of digital representations of fonts 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, the super sampling is a function of the weighting. During a scan conversion operation, RGB pixel sub-component values are independently determined from different portions of a scaled image. The scan conversion process may involve use of different weights for each color component. Processing 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： Image data processing and image rendering methods and systems whereby images are displayed on display devices having pixels with separately controllable pixel sub-components. Image data, such as data encoded in a three-channel signal, is passed through a low-pass filter to remove frequencies higher than a selected cutoff frequency, which obtain samples from the color components of the signal that map spatially different image regions to individual pixel sub-components. It has been found that color aliasing effects can be significantly reduces at a cutoff frequency somewhat higher than the Nyquist frequency, while enhancing the spatial resolution of the image. The image data is then passed through sampling filters. A generalized set of filters includes nine filters, one for each combination of one color and one pixel sub-component. The filtering coefficients of the filters can be selected to optimize of approximate an optimization of an error metric, which represents the color and luminance errors perceived on the display device. In this manner, a desired balance between color accuracy and luminance accuracy can be obtained. The samples mapped to individual pixel sub-components are used to generate luminous intensity values for the displayed 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 time 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. Also described are methods of processing pixels such that if it is determined that the overall luminance of a pixel is less than that of a foreground pixel and a background pixel, then a new set of red, green and blue luminance intensity values are generated and substituted for those of the pixel.
