Image Capture Autoexposure
Decide whether to manually specify the gain and exposure time (only recommended for advanced
users with difficult image capture situations).
*Enable
Disable
By default, exposure value is set to 10 ms and gain value is set to 50 when autoexposure is
disabled.

Gain/Exposure Priority for Image Mode
Alter the decoder’s gain/exposure priority when it acquires an image in Image Mode with auto
exposure enabled.
 Low Gain Priority: The decoder favors longer exposure time rather than higher gain to capture
an image. This ensures that the image is less noisy and produces fewer artifacts during
post-processing activities like image enhancement (sharpening). This mode is ideal for fixed
mount/fixed object image capture since the image acquired is susceptible to motion blur.
 Low Exposure Priority: The decoder favors higher gain over exposure to capture an image. This
results in an image that is less susceptible to motion blur at the expense of noise artifacts.
However, for most applications, the amount of noise is acceptable.
