Title: Reducing optical crosstalk and radial fall-off in imaging sensors

Abstract: An imaging device and an image crosstalk analysis device are described that may be used to reduce optical crosstalk and radial fall-off in image data. The imaging device may include an image processing unit that applies corrections to the raw image data using newly developed correction algorithms and correction parameters that are generated for the imaging device by the image crosstalk analysis device based on an analysis of uncorrected image data generated by the imaging device. The correction parameters generated for a single imaging device may be loaded to imaging devices of the same make and model as part of the imaging device manufacturing process. Due to the flexible nature of the described processing techniques in which the control parameters are used, improved image quality may be achieved in every image generated by the respective manufactured cameras.
