20H:
EXPTM[7..0]
21H:
EXPTM[15..8]
22H:
EXPTM[23..16]
[Exposure time (useconds) of the electronic shutter]
Initial data: EXPTM[23..0] = 0, data range: 0 to 16,777,215
Sets the exposure time for the electronic shutter.
Exposure time = EXPTM[23..0] useconds
When set as 0, the electronic shutter is OFF.
30H:
PGA[7..0]
[CDS gain] Initial data: PGA [7..0] = 0, data range: 0 to 255
Sets the CDS gain (programmable gain)
CDS gain = 7.44 + 0.04 x (PGA[7..0] x 2 + GOFS[7..0])dB
*GOFS[7..0]:
The gain offset (The value of the address 32H)
31H:
DGB[7..0]
[Digital gain] Initial data: DGB [7..0] = The factory adjusted value
Video level = (Input video level – CLAMP level) x (1 + DGB[7..0]/128) + CLAMP Level
*CLAMP Level
Clamp level (The calculated value of the address 38H)
32H:
GOFS[7..0]
[Gain offset] Initial data: GOFS[7..0] = The factory adjusted value, data range: 0 to 255
38H:
CLAMP[7..0]
[Clamp level] Initial data: CLAMP[7..0] = 9; data range: 0 to 31
Sets the clamp level (The clamp level of the black signal)
Clamp level = CLAMP[7..0] x 8 + 56
(for 12bit output)
Clamp level = (CLAMP[7..0] x 8 + 56) / 4
(for 10bit output)
Clamp level = (CLAMP[7..0] x 8 + 56) / 16
(for 8 bit output)
Whenever it is set greater than 31, it will automatically resets to 31.
