摘要： An online printing parameter establishment apparatus is used with a xerographic printing device for printing high quality prints given a target value. The xerographic printing device is capable of producing at least one print control patch on a photoreceptor and is capable of sensing a value of the at least one print control patch. The xerographic printing device has a plurality of sets of inherent performance characteristic values. The online printing parameter establishment apparatus includes a controller device and a switch device. The controller device is operative to produce a first database of different ones of the sensed values. Each sensed value is associated with a respective one of the plurality of sets of inherent performance characteristic values based upon the target value. The controller device is also operative to produce a second database of a plurality of control values. Each one of the control values is extracted from a respective one of the sensed values and the associated set of inherent performance characteristic values. Further, the controller device selects one of the control values which is closely comparable to the target value. A method for online establishment of print control parameters to render high quality prints using a xerographic printing process is also described.

摘要： A video-based vehicle headlight state monitoring method and system. A vehicle image can be captured by an image-capturing unit and converted to a grayscale image. The grayscale image can be processed to locate a front license plate and identify a position of a headlight region in front of the vehicle utilizing an algorithm. An average digital count with respect to brightness of the headlight region can be compared with average digital count with respect to brightness of several parts of the vehicle and a background region to determine the vehicle headlights ON/OFF status. The headlights can be considered ON if the digital count level of the headlight region is higher than the digital count of the several parts of the vehicle and the background region. A warning signal can be initiated to turn the headlights on during a special situation utilizing a signal generator.

摘要： What is disclosed is a system and method which addresses the problem of inheriting color management intent from a fleet color management LUT into a 4-to-4 cascaded LUT. The LUT is updated starting with a set of patches that either form a uniform or non-uniform grid of the LUT or can be projected to a uniform or non-uniform grid in the CMYK space using, e.g., PCA. A set of L*a*b* target as well a variable that serve the purpose of preserving the GCR and other elements of the fleet profile is obtained by passing the set of CMYK values to the fleet printer model. By iterating on the printer (or the printer model of the engine at the moment of the engine change) and converging to the targets, the engine device cmyk set is obtained. The LUT is formed between the uniform or non-uniform gridded CMYK and the device cmyk.

摘要： A filter array for a multi-resolution multi-spectral camera system is described which not only captures 2D images at multiple wavelength bands simultaneously but also at a spatial resolution that meets the demand for spatial feature extraction. The present system optimizes filter bands that provide high image contrast at the highest possible resolution to enable spatial feature extraction and other wavelength bands at lower resolution to achieve maximum number of wavelength bands (e.g. spectral resolution) for multi-spectral analysis. After determining the required spatial resolution and number of wavelength bands for spectral analysis, multiple filters are arranged in a geometric pattern with each filter being designed to have specified wavelength and spatial resolution. Physical sizes of filters differ within each filter group. This maximizes the detector usage while optimizing the trade-off between spatial resolution and spectral resolution. Filter gaps are fixed or tuned to wavelengths of interest.

摘要： What is disclosed is a novel system and method for generating a spectral matching guide for spot color print applications. Spectral matching values are determined for spot colors obtained from a library of spot colors. A spectral matching guide is created from the spot colors and their respective spectral matching values in a manner more fully disclosed herein. Thereafter, when a user desires to render a job in a particular spot color, the associated spectral matching value for that spot color can be obtained from the spectral matching guide. In other embodiments, recommendations in the form of a suggested printer to use, a media type, a halftone screen, and other meaningful assistance can be provided for selection of spot colors for a given print/copy job that are less sensitive to varying illuminations. The present spectral matching guide provides meaningful extensions in spectral color reproduction in print/copy job environments.
