28H:
DLY[7..0]
[The delay time for the trigger] Initial data:
：
DLY[7..0]
＝
0
、
Range: 0 to 255
This command sets the delay time that occurs from the trigger signal input to start exposure.
Delay time = 2us X DLY[7..0] (useconds)
31H:
DGB[7..0]
[The digital gain]
Initial data: DGB[7..0] = 0
Video level = (Input video level - CLAMP[7..0]) X (1 + DGB[7..0] / 64) + CLAMP[7..0]
CLAMP[7..0]
：
The clamp level (The value of the address 38H)
38H:
CLAMP[7..0]
[The clamp level]
Initial data: CLAMP[7..0] = 40
、
Range:
：
0 to 80
This command sets the clamp level (The clamp level of the black signal).
This value is as 10bit video image. When 8bit is selected, clamp level should be 1/4 of setting value.
3AH:
WBR[7..0]
[White Blance R Gain]
Initial data: WBR[7..0] = 0
、
Range: 0to255
This command sets the Red gain on Bayer.
Video level = (Input video level - CLAMP[7..0]) X (1 + WBR[7..0] / 64) + CLAMP[7..0]
3BH:
WBB[7..0]
[White Blance B Gain]
Initial data: WBB[7..0] = 0
、
Range: 0to255
This command sets the Blue gain on Bayer.
Video level = (Input video level - CLAMP[7..0]) X (1 + WBB[7..0] / 64) + CLAMP[7..0]
3CH:
WBGR[7..0]
[White Blance GR Gain]
Initial data: WBGR[7..0] = 0
、
Range: 0to255
This command sets the Green gain on Bayer GR line.
Video level = (Input video level - CLAMP[7..0]) X (1 + WBGR[7..0] / 64) + CLAMP[7..0]
3DH:
WBGB[7..0]
[White Blance GB Gain]
Initial data: WBGB[7..0] = 0
、
Range: 0to255
This command sets the Green gain on Bayer GB line.
Video level = (Input video level - CLAMP[7..0]) X (1 + WBGB[7..0] / 64) + CLAMP[7..0]
