Intelligent Imaging Explained
Intelligent Imaging is a method to automatically send an image or part of an image related to a bar code to a
host application. This method is reduces transfer time and file size while making the image capture easy.
An example of a signature capture application using Intelligent Imaging is located on page 7 of this Guide.
In this example, the operator reads the bar code, which is then transmitted to the host application. Upon the
receipt of the bar code data, the host application sends a command that tells the scanner to output only the
area of the image corresponding to the signature capture box. The scanner also automatically adjusts for
aspect ratio and distortion issues that arise due to scanner skew with respect to the bar code.
An important aspect of the Intelligent Imaging functionality is that all dimensions used in the application
are measured as multiples of the minimum element size of the bar code (the ‘X’ dimension). Using this
method, the Signature Capture application always outputs the correct image size and resolution no matter
the distance at which the scanner is held from the bar code, assuming that the entire signature capture area
is within the scanner’s field of view.
Intelligent Imaging Setup
Displays the settings for Intelligent Imaging applications.
Default settings are for the Signature Capture demo included in
this ISC-Imager Demo Application and described on page 7 of
this Guide.
• Barcode Aspect Ratio: Ratio of the minimum bar code
bar width vs. the height of the bar code.
• Horizontal (X) Offset: Offset from the bar code center
to the Intelligent Image window center in the X
direction, measured in minimum bar code bar widths.
• Vertical (Y) Offset: Offset from the bar code center to
the Intelligent Image window center in the Y direction,
measured in minimum bar code bar widths.
• Capture Area Width: Width of the requested image
window measured in minimum bar code bar widths.
• Capture Area Height: Height of the requested image
window measured in minimum bar code bar widths.
• Binary Image (Black and White): If set, this option causes the image to be transferred and displayed
in black and white instead of the standard grayscale.
• Code 39 Demo Page Settings: This option sets the above parameters to fit the Code 39 bar code
Signature Capture example found on the Sample Bar Code Pages in Appendix B.
• Aztec Demo Page Settings: This option sets the above parameters to fit the Aztec bar code
Signature Capture example found on the Sample Bar Code Pages in Appendix B.
