使用曝光调制和空间变化的TRC校正条纹的方法

Method of correcting streaks using exposure modulation and spatially varying TRCs
Abstract:
Systems and methods are provided for compensating for streak defects in images formed by an image forming device, such as a digital printer. The systems and methods include using both modulation of a raster output scanner (ROS actuation) and spatially varying tone reproduction curve (STRC actuation) in a common control system for improving streak correction. Low spatial frequency large amplitude streak defects are corrected using ROS actuation and high spatial frequency streak defects, as well as any residual low frequency defects, are corrected using STRC actuation.
