摘要： A method and system for matching digital information flow to the human perception system. In various embodiments, multi-monitor (multimon) support is leveraged to take advantage of multiple windowing and window positioning to separate elements of different tasks into information planes (which are based on a concept of “triage and focus”). Triage watches the flow of incoming information and determines the nature of the information. Based on the nature of the information and principles of human perception, Focus (or defocus) displays the information where the information is best viewed.

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： Color processing operations can be used to reduce color artifacts in images displayed on display devices having pixels with separately controllable pixel sub-components. Different regions of image data are mapped to the individual pixel sub-components of the pixels. In the absence of performing the color processing operations, distracting color artifacts can be generated in the displayed image as a result of the pixel sub-components being treated as independent luminous intensity sources. Color artifacts can be reduced by comparing the difference between the luminous intensity values of adjacent red and green pixel sub-components with a threshold value and adjusting the luminous intensity values so as to reduce the difference if it exceeds the threshold value. Color artifacts can also be reduced by performing a gray scaling operation on pixels having an overall luminance that is less than the luminance associated with a foreground color and also less than the luminance associated with a background color. Color artifacts can also be reduced by adjusting the luminous intensity values if a pixel has a color that falls outside a selected range of acceptable mixes of the foreground and background colors.

摘要： Methods, systems, and computer program products for adding hinting instructions to a character in order to improve a character bitmap produced from an outline of the character at a certain size and output resolution when the character outline is scan converted. A character is retrieved to be output. A determination is made that the character belongs to a semantic character classifications, and hinting instructions that are associated with the semantic character classification are accessed. The hinting instructions preserve semantic meaning for the character while altering either stroke presence, stroke location, or both for at least one stroke of at least one feature of the character based on a reference character size and output resolution. If the actual character size and output resolution for the character is within a reference character size and output resolution for the hinting instructions, the hinting instructions are executed.

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： Methods and apparatus are disclosed for sampling image data 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 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 of the image data to individual pixel sub-components, including mapping two or more samples to at least one of the pixel sub-component. As a result, each of the pixel sub-components represents 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： The present invention relates to methods and apparatus for increasing the perceived quality of displayed images. This is achieved in a variety of ways including the use of a plurality of device specific display characteristics when preparing images for display. It is also achieved through the monitoring of display device and/or ambient light conditions, e.g., on a periodic basis, and using the obtained information when controlling display output. Another approach to improving the perceived quality of displayed images involves the use of information relating to a specific user's ability to perceive image characteristics such as color. By customizing display output to an individual user's own physical perception capabilities and/or viewing characteristics it is possible to enhance the image quality perceived by the individual viewer as compared to embodiments which do not take into consideration individual user characteristics.
