  • Patent number: 10803629
    Abstract: The embodiments discussed herein involve flood filling a region with anti-aliasing. In forming a fill region, a candidate pixel can be included in the region based on a color of the pixel and also a color of a neighbor of the point. The inclusion basis may be a color distance between a seed color and the points, and a color distance between the seed color and the point's neighbor. Points in the region may be weighted according to their color distance relative to the seed color, where the color distance can also take into account alpha values. Flood filling may be anti-aliased by assigning alpha values to pixels in gaps between corners of the fill region, where an alpha value may be proportional to a point's contribution to the gap. Dimples in a fill region may be tested for and used to determine which of two flood fill algorithms to use.

  • Patent number: 8223402
    Abstract: What is disclosed is a novel system and method for color trapping on halftoned bi-level bitmaps. Color edges are detected and edge pixels that need to be trapped are identified. The number of pixels qualified as edge pixels eligible for color trapping can be up to a pre-determined number of pixels away from the color edge. Estimates for the continuous-tone values are obtained for the dominant colors on each side of the two-color edge. The contone value of the dominant color on the opposing side of the two-color edge is assigned to the qualified edge pixels. Qualified edge pixels are re-halftoned using their assigned contone value so that halftones for one color are extended beyond the edge into the other color. The re-halftoned edge pixels are combined with the original bitmap to produce a new bitmap for the image. The new bitmap is then provided to an image output device.

  • Publication number: 20100013854
    Abstract: Hybrid architecture of supersampling and computing distance from a feature edge or Bezier evaluation to address thin feature support in graphics systems. To avoid missing some features the technique creates a supersampling of a small number of supersamples to pick up the thin features. By supersampling, samples can be produced on both sides of a thin feature, which causes thin features to be detectable by some pixel. Now that the thin features hit some pixel, the quality is achieved by a distance-from-edge approach. For example, the technique can supersample four times in combination with the distance-from-edge approach, produce another four samples there resulting in a 16-sample result.

In one aspect of the invention, an exemplary method to scan convert an image on a data processing system includes: sampling the image in a first direction to generate first signals for points along a second line in a second direction using a closed form solution for a convolution integral with a first kernel; and weighting the first signals for the points according to a second kernel in the second direction to generate a second signal for a pixel. In one example according to this aspect, the closed form solution is tabulated in a look up table. After entries are looked up from the look up table according to the image along a first line in the first direction on a first point of the points, the entries are combined to generate one of the first signals for the first point.

  • Patent number: 7437765
    Abstract: A sensitive display system is described. The sensitive display system allows for mediation of content provided from a source to a recipient, such as from a web server to a web browser. Mediation may involve intercepting and augmenting the content so as to restrict or otherwise control information displayed on a display of the recipient device. In this way, the sensitive display system allows restricted information to be replaced with security status messages, or removed entirely. For example, when a user comes within a specified distance from the sensitive display area, a security classification level of the approaching user is used to determine whether there should be any change in the display. If so, a mediating device causes a browser push to occur, to thereby block or otherwise restrict some or all of the display.

  • Patent number: 7420593
    Abstract: A mobile communication terminal comprises a camera unit (34) and a main CPU. In the camera unit (34), a processing system including a color conversion circuit (66) and an image compression circuit (68) generates high-resolution compressed still image data based on interpolated image data of a photographed object. Also, a processing system including an image decompression circuit (74), a color conversion circuit (72), and a thinning-out circuit (70) generates low-resolution decompressed still image data based on the high-resolution compressed still image data. The main CPU activates an image compression circuit (68) when a release key is operated, and activates an image decompression circuit (74) when generation of the compressed still image data is completed. The low-resolution decompressed image data generated by activation of the image decompression circuit (74) is obtained by the main CPU from the camera unit and written into a VRAM. As a result, a decompressed image is displayed on an LCD.

  • Patent number: 7304648
    Abstract: A method (1005) generates one or more linear blends. Initially, the method has a list of already received one or more fill-paths defining a current linear blend, and a newly received fill-path, where the fill-paths each comprise a single colored parallelogram (eg. 700). The method adds (1090) the new fill-path to the list to become the last fill-path in the list, if the difference (1230) in color between the new fill-path and the last fill-path in the list is no greater, in each color channel, than a predetermined threshold value multiplied by the difference in color between the last and second-last fill-paths in the list. The predetermined threshold value is preset to such a value so that the new fill-path will not be added to the list if the new fill-path does not visually form part of the current linear blend. The method repeats this step for each new fill-path received until the aforementioned condition is not satisfied.

  • Patent number: 7164430
    Abstract: A system and method for rendering a non-zero thickness line on a pixel-limited output device such that aliasing of the line is reduced. The edges defining a line segment are expanded to insure that any pixel touched by the line segment has its center included in the bounds of the line segment. The area of any pixel partially or fully covered by the expanded line is determined. If one edge of the line traverses the pixel, the area is determined according to whether a triangular or triangular plus parallelogram area is covered. If more than one edge of the line segment traverses a pixel, the area covered is computed based on the single edge case. With the area covered by the line segment known, the color or shading of the pixel is determined by linear interpolation between the line and the background.

  • Patent number: 7106346
    Abstract: An n-filter according to the present invention includes a nonlinear filter, a pattern detector, and a switch. The nonlinear filter maintains a steep edge whose size is larger than a predetermined threshold in fluctuations of pixels constituting an input image signal and, at the same time, smoothes a non-edge portion that does not include the edge. The pattern detector detects a fine edge in the fluctuations of the pixels constituting the input image signal and notifies the switch that the fine edge exists. The switch outputs the input image signal or an image signal output from the nonlinear filter to the subsequent stage in accordance with the notification from the pattern detector.

  • Patent number: 6897879
    Abstract: Hardware acceleration of the rending and animation of characters that treat each pixel sub-component as a distinct luminance intensity source. A bit-map representation of the sub-component-oriented character is generated by using a single image sample to generate each pixel sub-component. This may be accomplished by, for example overscaling a representation of the character, placing the overscaled representation of the character on grid, and then assigning a luminance and possibly a transparency value to each grid position based on the property of the overscaled character at the grid position. The, the character is rendered by interfacing with a hardware graphic unit that perform the final rendering and animation of the character.
