8. Other functions
8.1 Black level control
(Command : BL)
This function adjusts the setup level.
Command value : -1024 to 1023
Variable range : -256 to 255 LSB (at 10-bit output)
8.2 Gain control (Relative commands GA,GJUT1,2,3)
The AM-800CL can adjust the gain level from -3dB to +24dB using 0dB as the reference
(Factory default). In the AB-800CL, the master gain can be adjusted from 0dB to +24dB and
R and B gains can be adjusted in the range of -7dB to + 10dB using the master gain as the
reference.
The AM-800CL and AB-800CL has the resolution of x0.00012/step using both analog
gain(0.00359db/step) and digital gain. In the AB-800CL, blue and red channels can adjust
in x0.00012/step by using digital gain.
Refer to the following drawing.
Fig. 36 Gain control
8.3 Tap control (Relative commands AWA,ABA,GJUT1, GJUT2,GJUT3)
The Tap control function adjusts automatically or manually the OFFSET and the gain
differences between the upper and lower taps, and the right and left taps.
The sensor
used in the AM-800CLand AB-800CL divides the effective image area into 4(four) areas as
shown in the figure 30 in order to achieve its fast frame rate.
The reference tap for all adjustments is Tap ”A”.
AWA:
Adjust the differences of the gain among taps automatically
ABA:
Adjust the differences of the OFFSET among taps automatically
GJUT1:
Adjust the gain of the TAP1R(B) manually
GJUT2:
Adjust the gain of the TAP2L(C) manually
GJUT3:
Adjust the gain of the TAP2R(D) manually
Note: 1) The OFFSET cannot be adjusted individually.
2) TAP A cannot be adjusted individually.
