You can set the Image Color Depth by selecting 256 gray levels (default), 16 gray
levels, or 2 gray levels. Higher color depths yield larger image files. This option is
ignored if the JPEG format is selected,(256 gray levels only).

Autoscanning

Normal Mode

Lynx™ provides an autoscan command (see par. 2.11.3), which when enabled,
causes the reader to scan continuously and to monitor the central zone of its reading
area. In this way, Lynx™ is ready to capture any image (containing a potential code)
positioned on a uniform background.
The aiming system can be enabled to indicate the reading area of the potential code
to be captured. The illumination system can also be enabled when the ambient light
conditions are not sufficient to autodetect the potential code to be captured;
furthermore, the illumination system increases in intensity for an instant when
capturing and decoding an image. A safety time may be defined to prevent Lynx™
from reading the same code repeatedly.
If the decoding is completed successfully, the reader starts monitoring the reading
area again. In case of decoding failure, Lynx™ keeps on decoding until a potential
code is present in the central zone of the reading area.

Pattern Mode

The Autoscan pattern mode is particularly advised when reading barcodes positioned
on a non-uniform background. In these cases Lynx™ may perceive some elements of
the background as barcodes and start the decoding. To avoid this undesired effect,
the Autoscan Pattern Code is placed in the Lynx™ reading area which prevents
decoding. Using this code as the background, code reading takes place normally by
presenting desired codes to be read over the Pattern Code. Between each code
read, the Pattern Code must be represented to Lynx™.
The Pattern Code can be printed from the file of the manual (Appendix C) available
on the CD-ROM.
In case of low ambient light conditions, Lynx™ automatically activates the illumination
system. If desired, the illumination system can be enabled so that it is always active.
