Imager
Adaptive Windowing
Adaptive Windowing is an advanced technique used to speed up bar code 
recognition in certain applications. The ‘Adaptive Windowing’ parameter 
automatically reduces the size of the window to the user-programmed window size 
when it successfully decodes (which reduces decode time the next time it is used), 
but increases it to the full size window (1280x1024 for SX5303) on a failed decode. 
Note: This feature assumes that you have reached an understanding about how 
the device operates in your application, and that, after a learning period, 
operators will get used to using the imager in one particular way. It also 
assumes that a trained operator will usually only have near miss scenarios. 
Constant Illumination
Constant Illumination is used to reduce the intrusiveness of the device’s illumination 
on the observer. Instead of the illumination turning on and off every time the device 
attempts a decode (2-4 times per second), the illumination stays on from the time the 
trigger is pulled until a decode is successful. This feature is useful in low light 
environments, since it will also reduce the distraction that the illumination can have 
on nearby coworkers.
