  • Patent number: 7411589
    Abstract: Methods and apparatus are provided for a color liquid crystal display (CLCD). The apparatus includes a processor coupled to the CLCD for receiving a character code and a color code and translating them into character and color pixel arrays that are overlaid and summed to produce a composite pixel array corresponding to the CLCD pixel array, where each entry in the composite array is used in conjunction with a color table to establish drive levels for each pixel in the CLCD. The character pixel array includes gray level color mixing and the color pixel array includes spatial shading color mixing, so that the composite array uses both techniques to determine the individual CLCD pixel drive levels to provide a wider range of color choices without significant color dependence on viewing angle.

  • Patent number: 7411593
    Abstract: A system, method and program product for rotating a first image in an image buffer such that the resulting, rotated image is substantially free of an aliasing error, i.e., broken lines, stair stepped edges, etc., is disclosed. An algorithm is applied to the first image that uses weighted sums of data points of the first image to create the rotated image. The weighting is based on the skew angle and data point location of the first image. The resulting rotated image also has a reduced data storage space requirement compared to rotated images created by prior art techniques.

  • Patent number: 7411595
    Abstract: Methods and products are disclosed concerning extraction of selected components of a warping of an image. Given a warped image and a distortion grid, the distortion at any point in the image may be viewed locally as a displacement and a linear transform. The linear transform can be manipulated to extract elements of the local distortion such as skew, rotation, magnification and combinations. The selected components may then be selectively applied at other locations of the same or a different image, using a variety of virtual paintbrushes for different effects.

  • Patent number: 7411596
    Abstract: In a gradation voltage generation circuit used in a video signal line driving circuit for driving video signal lines of a liquid crystal display device by time division based on switching control signals, a first variable resistor circuit is connected between one terminal of a voltage divider circuit for generating a gradation voltage group and a power source line for supplying a high-level voltage, and a second variable resistor circuit is connected between the other terminal of the voltage divider circuit and a power source line for supplying a low-level voltage. The resistances of the variable resistor circuits are switched based on the switching control signal. Thus, in the periods in which the video signal lines respectively connected to R, G and B pixel formation portions are driven, gradation voltages that are adapted to the gradation reproducibility for R, G and B are outputted respectively.
