Table 5-8. Image Quality Field Values
Field Value Description Values
Iris This controls the aperture of the high resolution camera’s lens. The larger the
value, the larger the aperture, the brighter the image. However, a larger aperture
also produces a shallower depth of field. A setting of 136 provides best image
quality. Default Value: 136
Valid Values: 0-255
Adaptive Exposure Allows the system to auto-sense the lighting conditions and adjust the exposure
accordingly. Intended for use in environments subject to gradual changes in light
conditions. Default Value: Off
Valid Values: On/Off
Threshold A threshold value, expressed as a percentage of change in lighting conditions,
above which the system will re-assess and adjust the exposure. Default Value: 10
Valid Values: 0-100
Exposure Exposure time, in milliseconds, for the high resolution camera. The longer the
exposure time, the brighter the image. The value for exposure can be changed
manually. Use the
Preview button to review results.
Default Value: 100
Valid Values: 1ms-255 ms
Light Sensor (lx) Environmental illumination as detected by the system’s light sensor. Default Value: 0
Valid Values: N/A
Light Sensor
Up/Down Low pass filter controlling how fast/slow the light sensor value will respond with
regards to instantaneous reading. Default Value: 50
Valid Values: 0-100
Gamma The gamma function brightens dark areas of an image, which corresponds more
to the perception of the human eye. In light areas of an image, the differences in
brightness are condensed for this. Default Value: 100
Valid Values: 1-1000
Gain High resolution camera gain setting. Default Value: 100
Valid Values: Camera
Dependent
Edge Enhancement Determines whether or not a sharpness filter should be applied to all high resolu-
tion images. This setting should normally remain at the default setting of On ,
which provides the best results for bar code and OCR definition.
Default Value: On
Valid Values: On/Off
