摘要： An apparatus for recording an image on a sheet comprises a linear array of light sources and an optical element for transmitting light emitted from the light sources. The optical element comprises a light-transmissive member, having an entry surface for disposal near the light sources. The entry surface defines at least one set of prisms. The optical element can further define a DCPC (dielectric compound parabolic concentrator) in cross-section. Collection optics, such as a SELFOC® lens, receives light reflected from the sheet. Each prism of the optical element defines an angle whereby light exiting the optical element is outside the acceptance angle of the collection optics.

摘要： A scanning apparatus includes an illuminator for illuminating a portion of a document to be scanned. The illuminator includes an array of discrete light sources and an optical element. The optical element includes a light-transmissive material and defines a focusing portion and an angular modification portion. The angular modification portion tends to reduce specular flare by modifying the angular distribution of light from the light sources which are within the acceptance angle of a lens arrangement which focuses light from the document onto a sensor.

摘要： A method and or a device for comprehensive temperature calibration of a full width array (FWA) image sensor may minimize loss of productivity and/or image quality. Multiple temperature sensors disposed along a width of the FWA image sensor may provide temperature points used to correct for temperature shifts in output of individual pixel sensors of the FWA image sensor. Under control of a microprocessor, a real-time correction may be calculated for each pixel of the FWA image sensor. The correction may be based upon a real-time temperature profile of the FWA image sensor and temperature dependent factors of at least one calibration equation. The factors may be predetermined, or be determined at factory test, at warm-up or at a specified time.

摘要： A method for removing show-through defects in scanned document images is provided by adjusting the scanner's image sensor calibration gain in the area of a drive roll gap. The method will also compensate for drive roll contamination. The invention uses a modified calibration scheme in conjunction with a document transmission sensor in the document handler to measure radiant energy transmitted through the document, i.e., transmission. The scanner adjusts the calibration gain factors to simulate a uniform background with knowledge of the gap and the input document's transmission thus a uniform scanner response is determined and presented to the image processing. A device for carrying out the method is also provided.
