2  Set up of InsperaScan 2.0

2.1 Install the required drivers

Each scanner model has its own driver and it must be installed on your computer prior to using InsperaScan. If you are using a scanner that has already been installed on your computer for use with other applications, you do not need to install it again.

InsperaScan can work with a variety of scanner models; however they must be tested before certifying compatibility.

 

2.2  Settings

Image Quality

Four available settings for the image quality in increasing order of disk space requirements for the files stored after processing:

  1. Monochrome (bitone): Converts image colours to either absolute black or absolute white based on their intensity level. It analyzes images at the pixel level. Every pixel below the "Monochrome Threshold" level will be considered black and every pixel above it will be considered white (see "Advanced settings").
  2. Greyscale: Converts colours to a 256 greyscale.
  3. Colour (24 bits): Stores the image as a 16 million colour image. Default setting. 

 

Auto stop

  • Scan continuously: The scanner will scan all forms in the input tray.
  • Scan one document only: The scanner will scan one document and stop even if there are more forms in the input tray. This is useful for testing purposes.

 

Load images from a folder

Note: When this option is selected, InsperaScan will not get images from the scanner when the "Scan" button is pressed.

This setting will load images from the folder specified in the corresponding text box. This allows the user to process images previously saved in this folder using other scanning software or network scanners. 

Several scanners could be set to store images in a centralized folder that InsperaScan could later process through this option. 

Note: Make sure that the images stored in this folder comply with InsperaScan's requirements:
  • Colour Images
  • 200 dpi resolution
  • .jpg .tif .tiff .png .jpeg file extensions
  • Images are in the right direction, complete (not cropped) and straight.

When InsperaScan loads images directly from the scanner, it will make the scanner stop when an image
cannot be processed for any reason (upside down, incomplete, incorrect form, etc.) so that the user can
correct the problem and scan it again. However, when it is loading the images from a folder, it will attempt to process them and if any image cannot be processed for any reason, it will be moved to a subfolder called "Unprocessed".

The button "Unprocessed" will be enabled when loading images from a folder. Pressing it will open a new
window that will allow the user to review and manually rename those unprocessed files and save them in
the same export folder as the rest of the images but with the letters ‘Man’ as part of the file name to
distinguish them from the automatically named files.

 

Scanner control

When a scanner is installed, a user interface is installed along with it. This interface allows the user to
interact with the scanner for configuring and operating purposes.

InsperaScan will try to control the scanner automatically without using the scanner’s user interface. When
the ‘Scan’ button is pressed, the scanner is automatically set to capture images with the right configuration and an order to start scanning is sent to it. Most times the scanner will respond to these  commands and the scanner will start scanning.

On rare occasions, some scanner models might not respond to InsperaScan’s commands and you may need to activate the scanner’s own user interface window in order to manually configure it and start scanning. On these occasions you can optionally set the scanner control to ‘manual’.

 

Advanced settings

  • Monochrome Threshold: This setting is only used when the ‘Image Quality’ setting ‘Monochrome’ is selected. The default value is 140 in a range from 0 to 255 where 0 is absolute black and 255 is
    absolute white. Change this setting only if you are not getting images as expected (too light or too
    dark). Press the ‘Default’ button to return its value to its default value.
  • OMR Threshold: This setting is used when evaluating the OMR areas to determine the presence of
    a mark. The default value is 180 in a range from 0 to 255 where 0 is the highest intensity and 255 is
    the lowest. Any strokes inside the OMR area with an intensity value above (lighter than) the OMR
    Threshold value will be ignored. Any strokes inside the OMR area with an intensity value below
    (darker than) the OMR Threshold value will be considered, and when the area covered by these
    strokes is significantly larger than other OMR areas in the same grid, a valid mark is acknowledged.
