    摘要： A system for providing color analysis of a toner image on an image bearing surface with a spectrophotometer is provided. The system includes an illuminator positioned adjacent to the image bearing surface and configured to emit a light beam at the image bearing surface, a linear sensor positioned adjacent to the image bearing surface and configured to receive the light reflecting off the toner image on the image bearing surface, a gradient index lens placed in the optical path of the light beams reflecting off the image bearing surface between the image bearing surface and the linear variable filter; and the linear variable filter positioned between the linear sensor and the gradient index lens. The system is devoid of a collimating lens positioned in between the gradient index lens and the linear variable filter, and the linear variable filter and the linear sensor are spaced apart by a gap.

    摘要： A method and system for camera calibration comprises configuring a calibration target comprising calibration reflectors on a test vehicle. Video of a test scene is collected. Next the test vehicle is identified as it enters the test scene and recorded as it passes through the test scene. The position of the calibration target in each frame of the video is determined and the corresponding individual position of each calibration reflector for each frame of the recorded frames is used to construct a camera calibration map to calibrate the video camera.

    摘要： A method and apparatus for measuring image on paper registration including placing a test sheet of media including a plurality of test pattern marks on a platen of an image sensing device. The platen defines a scan area over which the image sensing device is capable of scanning an image. The image sensing device includes a plurality of calibration marks falling within the scan area. The method further includes operating the scanner to scan the test sheet; determining a scanned position of the calibration marks and a scanned position of the test marks resulting from the scan; comparing the scanned position of the calibration marks with reference position of the calibration marks to determine scanning error; determining an adjusted position of the test marks responsive to the scanning error; and comparing the adjusted test mark positions with predetermined reference positions to measure registration accuracy. An edge guide disposed on the platen assists in aligning the test sheet for scanning.

    摘要： An image transfer assembly and method capable of adjusting the registration of an image printed on paper. A first image location being determined on at least one first sheet by measuring for each of at least three corners of a first sheet the distance between the two adjoining edges of the respective corners to a portion of at least one first fiducial mark. For each of the measured first sheet corners the measured portion of the at least one first fiducial mark is closer to that respective corner than any other of the first sheet corners. Then a second image to be transferred is adjusted by changing, relative to at least one second sheet, at least one of a size, shear, position and orientation of the second image based on the determined first image location. The adjusted second image being then printed on the second sheet(s).

    摘要： An apparatus compensates for mechanical disturbances during a print process by adjusting the generation of image generating head actuation signals in anticipation of a mechanical disturbance. The apparatus includes a printer controller for generating signals to coordinate movement of components with a rotating image receiver in a printer and for generating data identifying a process disturbance arising from interaction of the rotating image receiver with the components and an expected time for the process disturbance, a process disturbance compensator for generating a process disturbance compensation signal that corresponds to the process disturbance identification and timing data, and an image generating head controller for adjusting an image generating head actuation signal with the process disturbance compensation signal.
