摘要：A method for providing image illumination calibration includes: generating aplurality of images of a calibration target at a plurality of exposure levels, each image ofthe plurality of images being represented by a total pixel area; identifying a plurality of

zones of the total pixel area, each zone of the plurality of zones corresponding to aparticular image of the plurality of images at a particular exposure level of the pluralityof exposure levels, with each zone representing a pixel sub-area that excludes saturatedpixels; combining the plurality of zones for the plurality of images of the calibrationtarget to generate a final calibration image; and generating a shading table to correctthe final calibration image to obtain a uniform image of the calibration target over thetotal pixel area, the shading table including gain and offset values associated with eachpixel of the total pixel area.
