Decoding Autoexposure
Parameter # F0h,29h
Select Enable Decoding Autoexposure to allow the imager to control gain settings and exposure (integration)
time to best capture an image for the selected operation mode.
Select Disable Decoding Autoexposure to manually adjust the gain and exposure time (see Gain and Exposure
Time on the following pages). This option is only recommended for advanced users with difficult image capture
situations.
Decoding Illumination
Parameter # F0h, 2Ah
Selecting Enable Illumination causes the imager to flash illumination on every image capture to aid decoding.
