Light Leveling Impact Reference Guide
Datalogic Automation Inc. 3-48
scale factor is calculated for all the other columns or rows which brightens them so they have the same aver-
age grey level as the brightest column or row. Each column or row’s scale factor is then applied to all the
pixels in that column or row within the entire Region To Copy.
The light sensor area can be trained or recalculated on each image. The light sensor area is the ROI within
which the tool calculates the spatial light distribution in the image, which it then uses to adjust the pixel
intensities to be level across the entire image or the Region to Copy.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space
Light Sensor Shape
List
The region of the image to level. If no shape is defined, the entire image
is processed.
Region To Copy The region of the image to copy to the output image.
Direction To Level The tool levels the light in this direction (X, Y, or None). If leveling is
required in both directions, use two tools in series.
If None, no leveling is done.
Training Option No Training. Recalculate Sensor On Each Image
The light sensor is recalculated for each image.
Train Light Sensor On This Image
Trains the light sensor on the current image and then re-uses that level
on every subsequent image. This choice can save processing time on
each image if the light distribution within the image is static and repeat-
able.
Trained Sensor
Image
Holds the trained light sensor image. Since the tool levels in X or Y direc-
tions only, this image is an X or Y projection of the light sensor ROI, like
the output of the X-Y Projection tool.
