H’22:
SHR [7..0]
H’23:
SHR [15..8]
[ The preset shutter speed setting by the CLK.]
H’22 and H’23 set the preset value for electronic shutter speed.
SHR[15..0] represents the setting value(in the CLK) of the shutter speed.
＊The value replaces by 779 automatically when the value set greater than 779.
The preset shutter speed is defined by the following formula.
Shutter speed = SVR[15…0]
×
(1H cycle time)+SHR[15…0]
×
(1CLK cycle time).
＊The exposure time is one frame time(No shutter) when both SVR and SHR are set at “0”.
* The camera works with the minimum shutter speed when the value of SVR is set to 0 or between 1 and 306.
H’24:
PSR [7..0]
H’25:
PSR [15..8]
[ The start line of the variable partial scanning.]
This sets the start line number of the variable partial scanning area.
Actual start line of the partial scanning = setting value + 1
＊
The camera works with full line scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 494.
H’26:
PWR [7..0]
H’27:
PWR [15..8]
[The total effective line numbers in the variable partial scanning mode ]
This sets the number of the total effective lines (image height) in the variable partial scanning mode.
＊
The camera works with full scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 494 or when the value
is set at “0”..
H’28:
DLY [7..0]
[The delay time for the trigger ] Initial Data: DLY[7..0] = 0, Data Range: 0 to 31
This sets the delay time from the trigger input signal to the start of the exposure.
Delay time = 148CLK
×
DLY[7…0] (
μ
second)
Note: CLK = pixel clock time in
μ
seconds
H’30
PGA[7..0]
[CDS gain value] Initial Data: PGA[7..0] = 0, Data Range: 0 to 255
This sets the CDS gain, which is the programmable gain.
CDS gain is defined by this value as follows;
CDS gain = 3.64 + 0.132
× (PGA
[7..0] + GOFS[7..0]) (dB)
* GOFS[7..0]:
The value of the address
H’32
The analog gain of the CCD output is defined by the CDS gain as follows;
Analog gain = pre-amp (6dB) + CDS gain
H’31
DGB[7..0]
[
The digital gain value
] I
nitial Data: DGB[7..0] = The factory adjusted value (The value in the address H’0E)
The video output level is defined as follows;
Video output level = (Input Video level - CLAMP[7..0])
× (1 + DGB[7..0] / 128) + CLAMP[7..0]
* CLAMP[7..0]: The clamp level (The value of the address H’38)
H’32
GOFS[5..0]
[The gain offset value] Initial Data: GOFS[5..0] = The factory adjusted value (The value in the address H’0E)
Data Range: 0 to 63
H’38
CLAMP[7..0]
[CLAMP level] Initial Data: CLAMP[7..0] = 4, Data Range: 0 to 31
This sets the clamp level value of the black level.
＊The value replaces by 31 automatically when the value set greater than 31.
H’7E
FWVR[7..0]
H’7F
FWVR[15..8]
[Firmware version verification] Initial Data: FWVR[15..0] = Firmware Version
This value is used for the firmware version verification when the camera is powered on.
The data of the address H’10 to H’7F on the EEPROM are initialized with the factory default if this value and the value on
the register are not equal.
H’80
E2P[7..0]

・
D0:
= Writing control into EEPROM (*1) =

・
D1:
= Register synchronous update with the EEPROM (*2) =
0: Prohibited 1: Permitted
・
D2 - D7
= No Function =
Set always “000000”
*1 This bit is cleared to “0” automatically by the internal process after the execution of the command.
*2 By synchronizing to the EEPROM read/write access, the subject control register is also updated.
*The underline settings are the factory default settings
