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.
Lookup Table (LUT) Overview
The camera can save up to 8 user-programmable LUT tables as components of its
embedded processing features. A LUT is used for operations such as gamma adjustments,
invert, and threshold processes. The LUT in the camera is applied to red, green, and blue
equally. The LUT size is always 12-bits in and 12-bits out, as this is the size of the
processing chain in the camera, regardless of the bit resolution out of the camera.
Pixel data, when read out of the sensor, passes through the LUT memory array, where the
newly programmed pixel value then passes to the camera output circuit. The LUT data table
is stored along with other parameters using the user configuration function.
