摘要： A color output device is generally driven by at least three independent control signals for control of its response. A desired response in device independent color space is normally obtained by employing a cascade consisting of a characterization transform and calibration transform. The calibration transform transforms input control variables into output control variables that are directly used to drive the device. Input control variables can be transformed into intermediate control variables, which can be then mapped to output control variables utilizing a two-dimensional transformation. The two-dimensional calibration architecture provides improved control functionality and flexibility.

摘要： A marking engine forms one ore more toned patches and/or images on a photoreceptor transfer device such as a photoreceptor belt or drum, either within or outside a main image area. A sensor illuminates the tones patches and/or images on the photoreceptor transfer device using wavelegths outside the photo response range of the photoreceptor transfer device, thereby allowing reflectance values for each toned patch and/or image to be measured without generating ghost images on the photoreceptor transfer device. The sensor supports collection of measured reflectance values from single-color, mixed-color; and multi-separation image-on-image toned patches and/or images directly from the photoreceptor transfer device at rates as high as one or more times per revolution of the photoreceptor transfer device. The measured reflectance values may be used to generate and/or update color stabilization tone reproduction curves.

摘要： An embodiment generally relates to systems and methods for determining cell phone usage automatically by individuals operating vehicles. A processing module can process multi-spectral images or videos of individuals and detect different regions in the image such as face regions, hand regions, and cell phone regions. Further, the processing module can analyze the regions based on locations and numbers of skin pixels and cell phone pixels to determine if the individual is holding his or her cell phone near his or her face. Based on the analysis, it can be determined whether the individual is operating the cell phone. Further, the analysis can yield a confidence level associated with the cell phone usage.

摘要： A color sensor monitors the output of a color producing process and produces a signal representative of a color produced by the color producing process. The signal can be used as feedback signal to control the process. Occasionally, the color sensor signal includes a component representing a transient error. A system model of the color producing process is used to predict reasonable sensor signals. A comparison of the sensor signal with the predicted sensor signals is used to determine if the sensor signal is reasonable. If the sensor signal is unreasonable, a substitute signal is used as the feedback signal to the control process. The substitute signal can be a predicted sensor signal or a signal based on historical system performance data.

摘要： What is disclosed is a system and method for merit-based gamut mapping. In one embodiment, color points are clustered in regions of interest within a color space. Each cluster is associated with a gamut mapping function and a merit function. Mapping parameters of each gamut mapping function are iteratively varied to optimize the values based on the merit function value. An optimized gamut mapping function results. Optimized gamut mapping functions of adjacent clusters are blended together by blending the value of the gamut mapping function for a point of a cluster with a value produced by the gamut mapping function of an adjacent cluster for that color point. The composite gamut mapping function contains the optimized gamut mapping functions of all clusters is then output for use in mapping points within those clusters to points within the target gamut. The composite gamut mapping function exploits local advantages of each cluster.
