NEDXCM20125GIG UME-0041-01444.8.2 How to Obtain User Arbitrary Correction DataFill the camera field of view with a uniform white object. This will be used toobtain user arbitrary correction data. When using a lens, both the lens andillumination shading will be corrected at the same time; however to avoidnon-uniformities in the white object from affecting the correction, be sure todefocus the lens.Figure 4-8-2 Pixel Correction Registers (image from GigEGrab)Write “1” to the PixelCorrectDataSave register (in the included viewer softwareclick “Execute()” then press the Enter key), and the User Arbitrary CorrectionData will be written to the Flash Memory.Next, input the PixelCorrectSetLevel, and set PixelCorrectSetMode to UserWhiteto apply the User Arbitrary Correction Data.Notes:1) The above PixelCorrectSetLevel is a target value from 0-10232) The User Correction target value should be slightly higher than theobtained white data in order to output the full range possible.
