XRD9829REF 4 Rev. 1.00 OPERATIONAL PROCEDURE The routine listed below will first calibrate the photo response of the CIS using the XRD9829. After calibration, the XRD9829REF can be used to scan any color target to show CIS non-color corrected response. (Color correction is typically done in the digital asic.) How to Run the XRD9829REF Demonstration[...]
