ABSTRACT:
Producing calibration data (to remove vignetting, e.g., color-dependent vignetting) for a digital camera includes: arranging, in front of the camera, a white reference surface that is to be imaged; capturing, via the camera, a characteristic array of data corresponding to an image of the reference surface for each color that the camera can image; and manipulating each characteristic array to reduce a total amount of data representing the reference image.
