8.11.1 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
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 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 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 digital gain.
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.
