3.11.10 Test Image Eight (Uniform Black)
In test image eight, all pixels will have a red value, a green value and a blue value of 0 whether
the camera is set for 8 bit output or 10 bit output.
Test image eight should always appear as a uniform, black image as shown in Figure 3-37.
Test image eight is useful for checking the integrity of the data transmitted by the camera. If you
capture lines and examine the pixel values in the captured lines, the values should be exactly as
described above.
Test image eight is also useful if you want to see a visual indication of the effects of using DSNU
shading correction. If you enable test image eight and you also enable DSNU shading correction,
the effects of the DSNU shading correction feature will be visible in the captured test images.
(Normally, shading correction should be disabled when you use any test image. You should only
enable DSNU shading correction with test image eight if you want to see the effect that this type
of shading correction will have on a uniform image.)
