Image Brightness (Target White)
Parameter # 390 (SSI # F0h 86h)
This parameter sets the Target White value used in Snapshot and Video modes when using autoexposure.
White and black are defined as 240 decimal and 0, respectively. Setting the value to the default of 180 results
in a white level of ~180 for the image.
To set the Image Brightness parameter, scan Image Brightness below followed by three numeric bar codes
representing the value. Include leading zeros. For example, to set an Image Brightness value of 99, scan 0, 9,
9. See Appendix G, Numeric Bar Codes for numeric bar codes.
NOTE Image Brightness is effective only when Image Capture Autoexposure (parameter # 360) is disabled.
