摘要： Embodiments include systems and methods of detecting a blocked aperture in an image device. In certain embodiments, the system and method is used in mail processing of letters and flats. In certain embodiments, the image sensor captures an image of the front of an item. If the aperture of the image sensor is obstructed, a void will appear on the image of the item. The system can detect the void and increment an alarm count until a pre-defined threshold is reached wherein the system signals an alarm so that the blockage can be removed and the affected items can be re-introduced for correct processing. In another embodiment, images obtained when the aperture is expected to be clear of any items.

摘要： A compensating technique, implemented as an image processing block inserted in a chain of sequential image processing blocks, is used to achieve custom tuning at an end-user site to provide a customer a desired image quality (IQ) different from the factory calibrated one, or to simply compensate for drift in the image quality due to a number of factors including environmental conditions and/or system aging. The compensating techniques use a higher order polynomial to correct an actual input/output parameter relationship such that it is acceptably close to a pre-determined input/output parameter relationship for a given measurable parameter related IQ.
摘要翻译：被实现为插入到连续图像处理块链中的图像处理块的补偿技术被用于在最终用户站点实现定制调整，以向客户提供不同于出厂校准的图像质量的期望图像质量（IQ）或简单地补偿由于包括环境条件和/或系统老化在内的许多因素导致的图像质量漂移。补偿技术使用较高阶多项式来校正实际的输入/输出参数关系，使得其可接受地接近给定可测量参数相关IQ的预定输入/输出参数关系。

摘要： A method is disclosed as including scanning a first pixel of an image with a primary scanning line of a sensor, and scanning a second pixel of the image with a secondary scanning line of the sensor, wherein the first pixel is separated from the second pixel by a pitch of one or more scan lines. A compensation value is determined for one or more pixels of the image, wherein the compensation value is determined based, at least in part, on a mathematical operation comprising pixel values associated with the first and second pixels and the pitch. The method further includes compensating the one or more pixel values based, at least in part, on the compensation value, wherein the compensation value compensates for a reflection of light between the first and second scanning lines when the first and second pixels are scanned.

摘要： Image quality assessment test charts and objective image quality measurement systems may be used to evaluate the printer sub-system health before artifacts become objectionable to human observers. Diagnostic images may be printed to allow measurement of a number of system performance attributes, such as: density, banding, streak, granularity, mottle, color, gloss, gloss uniformity, edge gradient, raggedness, sharpness, background, registration, line width, and satellite measurements. By comparing these measurements to historical values or ideal values of the same measurements, preventive maintenance suggestions may be generated to avoid both unnecessary maintenance and objectionable print quality.

摘要： An image reading apparatus which is capable of preventing images read from a double-sided original from suffering an in-surface color irregularity on each of images read from the respective opposite sides of a double-sided original and a color difference between the front and reverse. A CCD line sensor reads a front-side original image. An image processing ASIC calculates shading correction data for performing shading correction on original image data read from the original image by the CCD line sensor, based on read luminance values obtained by the CCD line sensor by reading a plurality of halftone gradation patches thereon on a correction chart. The shading correction data calculated by the image processing ASIC is corrected based on read luminance values associated, respectively, with at least two of the gradation patches.
