  • Patent number: 10217438
    Abstract: A method and user interface for direct setting of black and white points. Black point is set using a slider and matching of gray shades. White point setting is performed by having a setting object move within a defined region, such as a square or circle, with the area where the setting object moves being adjusted dynamically based on the location of the setting object with respect to the defined region. When the area is the desired white, the setting is complete. Preferably the defined region has a varying color border to allow a reference for the user in moving the setting object. A more detailed setting of gray levels can be accomplished by providing a gray scale with reference points. Each reference point has an associated white point setting area, so that settings are developed for each reference point. Settings at other locations are determined by interpolation or extrapolation.

  • Patent number: 9098272
    Abstract: An automatic load detection system. A first reference signal that may be known apriori can be used for load detection. For example, the first reference signal may be used for invisible portion of a frame. The DAC receives the first reference signal and outputs a signal that is based on the first reference signal. The output of the DAC may have two known values depending on whether the load is coupled to the DAC, e.g., by having a different impedance. Thus, the output signal may be used for detecting whether the load is uncoupled from the DAC. If it is determined that the load is uncoupled from the DAC, the clocking signal to the DAC may be turned off. Thus, DAC no longer consumes power when the load is uncoupled, thereby saving power.

  • Patent number: 8319455
    Abstract: Systems and methods for controlling the output of a plurality of light sources. The system can include four or more light sources (e.g. light emitting diodes (“LEDs”)) and a controller. The light sources are included in, for example, a luminaire. The respective outputs of the plurality of light sources are controlled using a hue and purity (“HP”) control technique. The HP technique includes selecting a dominant hue (e.g., green, blue, red, etc.). The purity of the selected hue is then modified to include or remove wavelengths of light adjacent to the selected hue. For example, if the selected hue is green, gradually reducing the purity of the selected hue gradually increases the presence of cyan and amber in the output of the luminaire. As the purity is reduced further, additional wavelengths of light are included, but the output of the luminaire remains, in essence, green.

    Abstract: To make it easy to specify a terminal (wireless communication device) connected to an access point (wireless connection device) by performing display corresponding to the access point to which the terminal is connected. A wireless connection device reads, from a storage unit, specified information for designating a display mode for specifying a connection of the wireless connection device itself, performs wireless communications with a wireless communication device, and notifies the wireless communication device of the specified information read from the storage unit. On the other hand, the wireless communication device performs the wireless communications with the wireless connection device, receives the specified information from the wireless connection device, and conducts the display in the display mode designated in the specified information.

  • Patent number: 7268748
    Abstract: A cathode ray tube (CRT) device increases image resolution using spatial or temporal techniques. The CRT device includes a plurality of electron guns that each produce an electron beam and a plurality of separate phosphor dots, each corresponding to one of a plurality of primary colors. Certain ones of the phosphor dots form a color spot of a single primary color when impacted by an electron beam. The CRT device also includes steering electronics coupled to the plurality of electron guns to guide the electron beams to project on the phosphor dots to form a plurality of color spots each indicating a different one of the primary colors. The steering electronics direct the electron beams to separate and shift the color spots indicating the different primary colors from one another. In one embodiment, a subpixel clock is coupled to the steering electronics to effect subpixel rendering on the CRT device.

  • Patent number: 7218291
    Abstract: A fragment processor includes a fragment shader distributor, a fragment shader collector, and a plurality of fragment shader pipelines. Each fragment shader pipeline executes a fragment shader program on a segment of fragments. The plurality of fragment shader pipelines operate in parallel, executing the same or different fragment shader programs. The fragment shader distributor receives a stream of fragments from a rasterization unit and dispatches a portion of the stream of fragments to a selected fragment shader pipeline until the capacity of the selected fragment shader pipeline is reached. The fragment shader distributor then selects another fragment shader pipeline. The capacity of each of the fragment shader pipelines is limited by several different resources. As the fragment shader distributor dispatches fragments, it tracks the remaining available resources of the selected fragment shader pipeline.

  • Patent number: 7215341
    Abstract: A method of coloring a plurality of cells using a predetermined fill-color, the cells occupying a region in a grid of cells thereby defining a plurality of region-cells, the method comprising: (a) dividing the grid into a plurality of elementary-regions, each comprising at least one cell; (b) visiting one elementary-region at a time and determining, for each cell of the elementary-region, whether the cell is a region-cell; (c) writing color data in at least one region-cell of each elementary-region using a color selected from a color-space so as to store information in the elementary-region, the information directing a backtracking path in the region, thereby providing a mapped elementary-region; and (d) using the information for visiting all the mapped elementary-regions along the backtracking path and for writing color data using the fill-color in each region-cell of each of the mapped elementary-region along the backtracking path; thereby coloring all the region-cells by the fill-color.

  • Patent number: 7006104
    Abstract: An image server transmits reference image data to a mobile telephone having a display device on which the reference image is displayed. A wavelength vs. luminance characteristic of the displayed reference image is measured by a radiance measurement unit, and a correction parameter for the mobile telephone is calculated based upon the measured wavelength vs. luminance characteristic. Processing for calculating correction parameters is executed with regard to other mobile telephones as well. If an image-data transmit request is issued by a mobile telephone, the image data is corrected using the correction parameter that corresponds to the mobile telephone. The corrected image data is transmitted to the mobile telephone. Since a correction suited to the mobile telephone is carried out, an excellent image is displayed on the display screen of the mobile telephone.

  • Patent number: 6897876
    Abstract: A method for transforming three color input signals (R, G, B) corresponding to three gamut defining color primaries to four color output signals (R?, G?, B?, W) corresponding to the gamut defining color primaries and one additional color primary W for driving a display having a white point different from W includes the steps of: normalizing the color input signals (R,G,B) such that a combination of equal amounts in each signal produces a color having XYZ tristimulus values identical to those of the additional color primary to produce normalized color signals (Rn,Gn,Bn); calculating a common signal S that is a function F1 of the three normalized color signals (Rn,Gn,Bn); calculating a function F2 of the common signal S and adding it to each of the three normalized color signals (Rn,Gn,Bn) to provide three color signals (Rn?,Gn?,Bn?); normalizing the three color signals (Rn?,Gn?,Bn?) such that a combination of equal amounts in each signal produces a color having XYZ tristimulus values identical to those of the
