Dark value offset (W)
Dark value offset is an 8-bit parameter that is added to the pixel data. It adjusts
the dark level and avoids clipping of pixels to black in low-light situations. The
eight bits are aligned to the lowest significant bit of the 10-bit raw pixel data
from the sensor.
If the digital gain is not active (
G=0), each increment of four increases the out-
put grey level just by one count.
Version information (V)
The command
V displays information about the camera model and firmware ver-
sion.
U=1
Enable metadata overlay
The overlay occupies the first (top left) 8 pixels of each frame.
Metadata format for the left Camera Link channel (connectors
O2/O1 or CL1/CL2):
•
Pixel offset 0–3 (4 bytes): constant ASCII characters CM4L
•
Pixel offset 4–7 (4 bytes): 32-bit frame counter, LSB first
(Intel format)
Metadata format for the right Camera Link channel (connectors
O4/O3):
•
Pixel offset 0–3 (4 bytes): constant ASCII characters CM4R
•
Pixel offset 4–7 (4 bytes): 32-bit frame counter, LSB first
(Intel format)
U=10
Enable test image generator. Full test image appears with
N=6BD, I=1, G=0 and D=0.
U=11
Enable metadata overlay and test image generator.
(Others)
Reserved for future use
Note
•
The effective image size and also the frame rate depend
on the corresponding camera settings such as e.g.
D, N
or
M. Edge markers are only fully visible if all 1726 active
lines are output.
•
The digital gain setting
G also applies to the test image,
but the FPN correction
C
is temporary disabled.
