Region of Interest (ROI)
The ROI feature is related to flat field calibration. It is important to specify an ROI when the object being
imaged has areas that have black, non-illuminated areas such as beyond the edge of a film that is front
illuminated, or is saturated, again beyond the edge of a film but in this case bright field back illuminated.
The ROI feature allows from one to four specific regions of the pixel line to be specified where flat field
calibration will take place. Pixel data outside the ROI will not be used when performing flat field
calibration.
Image Format Control Category
The Image Format controls, as shown by CamExpert, groups parameters used to configure camera pixel
format, image cropping, and test pattern.
Parameters in gray are read only, either always or due to another parameter being disabled. Parameters
in black are user set in CamExpert or programmable via an imaging application.
Features listed in the description table but tagged as
Invisible
are usually for Teledyne DALSA or third
party software usage—not typically needed by end user applications.
