3.10.5 Test Image Three (Uniform Black)

In test image three, all pixels will have a value of 0 whether the camera is set for an 8 bit output
mode or for a 10 bit output mode.

Test image three should always appear as a uniform, black image.

Test image three 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 three is also useful if you want to see a visual indication of the effects of using DSNU
shading correction. If you enable test image three and you also enable DSNU shading correction,
the effects of the DSNU shading correction feature will be visible in the captured test images.

3.10.6 Test Image Four (Uniform Gray)

In test image four, all pixels will have a value of 64 when the camera is set for an 8 bit output mode.
When the camera is set a 10 bit output mode, all pixels will have a value of 256.

Test image four should appear as a uniform, gray image.

Test image four 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 four is also useful if you want to see a visual indication of the effects of using PRNU
shading correction. If you enable test image four and you also enable PRNU shading correction,
the effects of the PRNU shading correction feature will be visible in the captured test images.

L

The description above of the pixel values in test image three is only valid when the
gain, gain balance, offset and offset balance parameters are all set to 0 and shading
correction is disabled.

L

The description above of the pixel values in test image four is only valid when the
camera is set for an 8 bit output mode and the gain, gain balance, offset and offset
balance parameters are all set to 0 and shading correction is disabled.
