摘要： A method of calibrating digital images having pixels with pixel values includes the steps of: exposing a photographic element to form a latent image of a reference calibration target including a plurality of reference calibration patches; exposing the photographic element to form a latent image of a scene; processing the photographic element to form developed images from the latent images on the photographic element; scanning the developed images to produce digital images; measuring the pixel values of the digital image of the reference calibration target to produce a measured value for each of the reference calibration patches; obtaining an aim value and adjustment data corresponding to each reference calibration patch; generating image calibration corrections using the measured values, the aim values, and the adjustment data; and applying the image calibration corrections to the digital image of the scene.

摘要： Reference calibration patches (512,514) produced by a sequence of exposures on a photographic element, the photographic element (510) exhibiting linear defects in a predominant direction, are arranged in a two dimensional array and exposures are assigned to the reference calibration patches (512,514) in the array such that nearest neighbors in the predominant direction are not nearest neighbors in the exposure sequence, whereby the effects of a linear defect are reduced; and the maximum number of steps in the exposure sequence between a reference calibration patch and that of its nearest neighbors in any direction is less than a predetermined number, whereby the effects of flare are reduced.
