101: No function (Do not set)

/ BayerRGB8Packed (Color)

100 to 111: No function (Prohibited setting. Do not set these values)

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 = 6.16 + 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.
