Test Image 3 - Moving Diagonal Gray Gradient (12 bit)
The 12 bit moving diagonal gray gradient test image is similar to test image 2, but it is a 12 bit
pattern. The image moves by one pixel from right to left whenever a new image acquisition is
initiated. The test pattern uses a counter that increments by one for each new image acquisition.
The mathematical expression for this test image is:
Gray Value = [column number + row number + counter] MOD 4096
Test Image 4 - Moving Diagonal Gray Gradient Feature Test (8 bit)
The basic appearance of test image 4 is similar to test image 2 (the 8 bit moving diagonal gray
gradient image). The difference between test image 4 and test image 2 is this: if a camera feature
that involves digital processing is enabled, test image 4 will show the effects of the feature while
test image 2 will not. This makes test image 4 useful for checking the effects of digital features such
as the luminance lookup table.
Test Image 5 - Moving Diagonal Gray Gradient Feature Test (12 bit)
The basic appearance of test image 5 is similar to test image 3 (the 12 bit moving diagonal gray
gradient image). The difference between test image 5 and test image 3 is this: if a camera feature
that involves digital processing is enabled, test image 5 will show the effects of the feature while
test image 3 will not. This makes test image 5 useful for checking the effects of digital features such
as the luminance lookup table.
