1.18.7 Working with LUTs
There are several use cases concerning LUTs (Look-Up-Tables):
• Introducing LUTs (p. 157)
1.18.7.1 Introducing LUTs
1.18.7.1.1 Introduction
Look-Up-Tables (LUT) are used to transform input data into a desirable output format. For example, if you want to
invert an 8 bit image, a Look-Up-Table will look like the following:
Figure 1: Look-Up-Table which inverts a pixel of an 8 bit mono image
I.e., a pixel which is white in the input image (value 255) will become black (value 0) in the output image.
All MATRIX VISION devices use a hardware based LUT which means that
• no host CPU load is needed and
• the LUT operations are independent of the transmission bit depth.
1.18.7.1.2 Setting the hardware based LUTs via LUT Control
Note
The mvBlueFOX cameras also feature a hardware based LUT. Although, you have to set the LUT via
Setting -> Base -> ImageProcessing -> LUTOperations (p. 158), you can set where the processing
takes place. For this reason, there is the parameter LUTImplementation. Just select either "Software" or
"Hardware".
