1. An imaging device, comprising: an optical sensing unit that generates image data containing a plurality of color channels; a data storage unit that stores the generated image data and a plurality of image correction parameters; and an image processing unit that processes the color channels to remove optical crosstalk and radial fall-off distortion based on the stored plurality of image correction parameters, the image processing unit including a Bayer space adaptation unit that converts Bayer space formatted image data to R, G 1 , G 2 , B data prior to a removal of optical crosstalk and radial fall-off distortion and converts the R, G 1 , G 2 , B data to Bayer space after the removal of optical crosstalk and radial fall-off distortion.
