摘要： A method of resolution conversion is disclosed. The method calculates a scaling factor for a first set of discrete data values compared to said second set of discrete data values. A plurality of filter function coefficients are calculated, based on the scaling factor, utilising at least one of a plurality of filter functions. The filter function coefficients are stored and later used to perform interpolation on the first set of discrete data values to generate the second set of discrete data values at a different resolution.

摘要： In a method for changing the size of line elements on a printed page, first the nature of the size change is determined and a positive/negative identifier identifying the nature (positive/negative) of the line elements is determined for each pixel of the printed page. A copy window whose expanse determines the desired size change is defined around a substitution field. Copy window and substitution field are displaced across the printed page, and the density values of the copy window are compared to the density value of the substitution field in each window position. Dependent on the nature of the size change, on the positive/negative identifier determined for the substitution field and on the result of the density value comparison, a decision is made in each window position for the substitution field as to whether the density value of the substitution field is replaced by a characteristic density value of the copy window or by a part thereof or not in order to achieve a broadening and/or narrowing of the line elements.

摘要： A computer graphics system efficiently implements a pixel zoom function. The graphics system includes a rasterizer designed to define a new zoomed (enlarged or reduced) raster image of a region in an original raster image having pixels defined in a coordinate system with orthogonal first and second axes (x,y), the region comprising a plurality of original pixels. The region to be zoomed can be modified differently along its x, y axes. In other words, the region may be enlarged (positive zoom) along one axis, while reduced (negative zoom) along the other axis, or either enlarged or reduced by different magnitudes (zoomX, zoomY) along the x, y axes. Furthermore, the zoom magnitudes may be integers (integer zoomX, integer zoomY) or floating point numbers (float zoomX, float zoomY). The rasterizer is designed to (1) determine a starting raster position for the zoomed raster image; (2) determine a first number of first pixels along the first axis for each row of the original pixels; and (3) determine, for each row of the original pixels, a second number of second pixels along the second axis for each column of the original pixels. A rendering mechanism associated with the pixel zoom system is designed to render the zoomed image based upon the starting raster position, the first numbers corresponding with the original pixel rows, the second numbers corresponding with the original pixel columns.

摘要： A method is disclosed for integrating a message such as an icon at a specified location within a graphical image. The method includes the steps of first retrieving transformation parameters associated with the specified location of the graphical image. The message or icon is then transformed in accordance with the retrieved transformation parameters and subsequently superimposed on top of the graphical image. As a result, an integrated image is created which is conveyed to the electronic display. The method has particular industrial applicability to streamed content such as conveyed on television and over the Internet. Also disclosed is a method for identifying transformation parameters useful in specifying a locality within a graphical image wherein a frame of a graphical image is displayed as a background image and a another, preselected message is displayed as a foreground image. The method permits translation and scaling of the foreground image while the background image remains unaffected. Transformation parameters are obtained and associated with that frame of the graphical image.

摘要： An image scaling method and apparatus converting an input image into an aimed image with suitable resolution for application, in the case that the input image and the aimed image are different in resolution, using continuous domain filtering and interpolation method. The invention utilizes domain filter of regular square type and generates filter coefficient based on area occupancy ratio of filter window according to the area of corresponding pixel extending the applied filter window and then obtains scaled image through the method of computing weighted average value, which is determined through multiplication of the generated filter coefficient and value of each pixel. By using image scaling method of the invention, there is an advantage of much lower cost in hardware implementation of an image scaler in comparison with conventional image scaling methods.

摘要： The present invention is directed to a system and method for magnifying a display of video data. In an exemplary embodiment, a system for magnifying a display of data includes a receiver for receiving a first set of video data including video data formatted for display in a first resolution. A translator is also included for translating the first set of video data formatted for display in the first resolution to a second set of video data formatted for display in a second resolution, the second resolution being a lower resolution than the first resolution. A magnifier is also included for magnifying a display of video data by formatting the first set of video into a third set of video data. The third set of video data is capable of display on a display device capable of displaying video data in the second resolution and incapable of displaying video data in the first resolution. The third set of video data is in an enlarged format with respect to the second set of video data.

摘要： A system and method for high definition video rescaling comprises receiving a source image including source pixels each having an associated amplitude, creating destination pixel locations for a rescaled image in accordance with a resealing factor, providing a normalized filter function, multiplying the normalized filter function with the amplitude of each source pixel to produce a filter function for each source pixel, and summing together the filter functions for the source pixels to generate a reconstructed function. The reconstructed function is sampled at the destination pixel locations to provide amplitudes for destination pixels. The amplitudes of the destination pixels are then incorporated into a rescaled image. The filter function is preferably a sinc product function. The sinc product function is a first sinc function having a first period multiplied by a second sinc function having a second period that is an odd integer multiple of the first period, so that the sinc product function has a smaller amplitude than a sinc function as the function converges to zero.

摘要： A directed graph is logically zoomed, whereby the appearance of a node directly related to a target node can be exaggerated and the structure of an entire graph can be readily understood. A directed graph is used in which hierarchical nodes are connected by arcs. In the directed graph, a node that has a predetermined logical relationship with a selected node is displayed differently than are the other nodes. For example, a displayed node logically near the selected node is large, while a displayed node logically distant is small, or the node logically near the selected node is moved closer to the selected node.
