8.10.1 Test Images in Detail
Test Image 1 - Fixed Horizontal Gray Gradient (8 bit)
The 8 bit fixed horizontal gray gradient test image is best suited for use when the camera is set for
monochrome 8 bit output. The test image consists of fixed horizontal gray gradients ranging from 0
to 255.
The mathematical expression for this test image is:
Gray Value = [column number] MOD 256
Test Image 2 - Moving Diagonal Gray Gradient (8 bit)
The 8 bit moving diagonal gray gradient test image is similar to test image 1, but it is not stationary.
The image moves by one pixel from right to left whenever a new line acquisition is initiated. The test
pattern uses a counter that increments by one for each new line acquisition.
The mathematical expression for this test image is:
Gray Value = [column number + counter] MOD 256
