发明名称 Reducing optical crosstalk and radial fall-off in imaging sensors
摘要 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.

主权项 1. An imaging device, comprising: a sensing unit configured to generate image data containing a plurality of color channels; and a processing unit configured to process the color channels to remove a distortion based on a plurality of image correction parameters, the processing unit including an adaptation unit configured to convert the image data from a first space formatted image data to R, G1, G2, B data prior to a reduction of the distortion and convert the R, G1, G2, B data back to the first space formatted image data after the reduction of the distortion.
