摘要： Passive wands, tracked by one or more cameras, are used as user interface devices. The wands are inexpensive, and are a natural way for users to interact with devices such as large displays. Each wand may be used to specify a full 6 degrees of freedom, which can be helpful for manipulation of 3D applications. The wands may also be used to identify 3D world points, which is useful for multi-camera calibration, and for building 3D models of physical spaces. The described methods provide a more precise estimation of wand pose, and can be implemented with a single camera. Also described is a method for estimation wand pose using information available along a one dimensional ‘line scan’ within the image, which simplifies processing.

摘要： Systems and methods for providing a status of a teleconference by determining an approximate delay time and providing a status signal in view of the determined approximate delay time are provided. An approximate delay time is approximately the amount of time that will elapse before an occurrence occurring at a first time, which is captured into an occurrence signal by a source unit, will be experienced at a second time after the occurrence signal is received by at least one receiving unit.

摘要： A first nonlinear conversion section converts input color signals of a kind that is one of plural, different kinds to L*a*b* signals. A second nonlinear conversion section converts the L*a*b* signals to image recording signals of four colors including black. The first nonlinear conversion section includes an input judgment device for judging the kind of input color signals, a weight memory for storing weights for the respective kinds of color signals, and a nonlinear conversion circuit. The weights corresponding to the kind of input color signals identified by the input judgment device are read from the weight memory and set in the nonlinear conversion circuit. The first nonlinear conversion section further has a learning device to accommodate color signals whose conversion relationship with the L*a*b* signals has not been defined.

摘要： Device independent color signals in color coordinates of the calorimetric system are computed using the color signals Ci, Mi, Yi, Ki in first CMYK coordinates. A maximum quantity of black maxKi of the color signals Ci, Mi, Yi, Ki is computed by using the color signals Ci, Mi, Yi, Ki and the device independent color signals. A black ratio g of the color signals Ci, Mi, Yi, Ki is computed using the maximum black quantity maxKi and the color signal Ki. A maximum quantity of black that can be obtained without changing the device independent color signals is computed using the device independent color signals. The color signal Ko in second CMYK coordinates is determined by the maximum black quantity and the black ratio, and the color signals Co, Mo, Yo, Ko in the CMYK coordinates are determined by using the device independent color signals and the color signal Ko.

摘要： Input color signals are input at step S11 and are converted into first CMYK color material amounts to minimize a first distance function at step S12. At step S13, color coordinates reproduced from the first CMYK color material amounts are obtained based on a printer model. If the input color signals are determined within a color reproduction range at step S14, the first CMYK color material amounts are output at step S22. If the input color signals are determined outside the color reproduction range, reproduced lightness is compared with input lightness at step S15. If the reproduced lightness is less than the input lightness, lightness weight .alpha. responsive to a yellow saturated color rate is used to generate a second distance function at steps S16-S18. On the other hand, if the reproduced lightness is equal to or greater than the input lightness at step S15, a second distance function having weight as a constant is generated at steps S19 and S20. Second YMCK color material amounts to minimize the second distance function are calculated at step S21 and are output at step S22.

摘要翻译： 在步骤S11输入输入颜色信号，并将其转换为第一CMYK颜色材料量，以在步骤S12将第一距离功能最小化。 在步骤S13中，基于打印机模型获得从第一CMYK颜色材料量重现的颜色坐标。 如果在步骤S14在颜色再现范围内确定输入颜色信号，则在步骤S22输出第一CMYK色材料量。 如果在颜色再现范围之外确定输入颜色信号，则在步骤S15将再现亮度与输入亮度进行比较。 如果再现亮度小于输入亮度，则在步骤S16-S18，使用响应于黄色饱和色彩速率的亮度权重α来产生第二距离函数。 另一方面，如果在步骤S15中再现的​​亮度等于或大于输入亮度，则在步骤S19和S20中产生具有权重作为常数的第二距离函数。 在步骤S21中计算出使第二距离功能最小化的第二YMCK颜色材料，并在步骤S22输出。

摘要： A method of determining lattice point data of a look-up table for transforming input color coordinates into colorant coordinates of a color image output device, or of reconstructing the same by using a differentiable-continuous function. An input-output characteristic of the device is determined by using a differentiable-continuous function based on discrete transformation pairs, and coefficients of color transformation that uses a look-up table or a continuous function is determined based on the thus-determined differentiable-continuous function.

摘要： An input data group is converted into an output data group in accordance with coefficients. For each coefficient, a current coefficient value, a coefficient value greater than the current coefficient value and a coefficient value smaller than the current coefficient value may be computed. One of the current, greater and smaller coefficient values is selected on the basis of errors between the output data computed with the current, greater and smaller coefficient values and an ideal output data group corresponding to the input data group.
