In this “pulse width trigger mode” with positive polarity, the camera exposure starts at the rising edge of the
trigger signal and stops at the falling edge of the trigger signal. Therefore, in the case that the exposure positive
polarity is selected, the actual exposure occurs when the trigger signal is at high state.

3.4 H Reset Mode

Normally, video noise appears when the beginning of trigger signal is applied before finishing the video read-out
of the previous frame. This noise is caused by the SUB pulse, which is activated to clear all residual charges on the
CCD prior to a new exposure. By selecting this “H. Reset Mode”, the camera automatically holds the actual activation of
trigger until the next horizontal blanking period. By doing this, the SUB pulse is activated during the horizontal blanking
period and the noise in image can be avoided.

Due to the principal of this operation, there can be maximum “1 H” of delay of actual trigger signal.

The data length is dependent on each read command sent.
The data length is defined as “00H” when sending the write command.
The data length of error response is defined as “00H”.

Sending frame:

The data length is 1 byte dummy data when sending the read command, and that data is
not referenced.

【Sequence for the saving commands to the EEPROM】

Please use the following sequence for saving the commands to the EEPROM.

1) Set “1” to the 80H.0 to enable writing to the EEPROM.

2) Send the save data with the page selection “1”.

3) The camera sends back one of the following receiving codes after writing the EEPROM.

01H: OK
10H: NG

4) 80.0H is cleared to “0” automatically after writing the EEPROM.

Note1: The data cannot be saved to the EEPROM when 80H.0 is “0”.

Note2: When saving the consecutive sequence of commands, the above steps, 1) to 4), are necessary only once.

i.e.) saving the commands “10H, 11H, 12H, 13H”, or “22H, 23H, 24H”, etc.

Note3: When saving the non-consecutive sequence of commands, the above steps, 1) to 4), are necessary for the

same number of times.

i.e.) saving the commands “10H, 13H, 19H, 1BH” or “20H, 23H, 25H”, etc.

[Exposure time (H) of the electronic shutter]

Initial Data: SVR[150] = 0, Data Range: 0 to 4095

Sets the preset shutter speed (or CCD exposure time) for electronic shutter.

The preset shutter speed is defined by the following formula.

Exposure time (shutter speed) = SVR[150] x (1H cycle time) + SHR[150] x (1CLK cycle time)

Notes:

1. The camera works with the shutter off position (maximum frame exposure time) when both SVR and

SHR are set at “0”.

2. The camera works with the minimum shutter speed when this value is set to 0 and the value of SHR is

set between 1 and 600.

3. The value is replaced with 4095 automatically when the value set greater than 4095.

[Exposure time (CLK) of the electronic shutter]

Initial Data: SHR[150] = 0, Data Range: 0 to 1923

Sets the preset shutter speed (or CCD exposure time) for electronic shutter.

The previous section, the preset shutter speed is defined by the following formula:

Preset shutter speed = SVR[150] x (1H cycle time) + SHR[150] x (1CLK cycle time)

Notes:

1. The camera works with the shutter off position (maximum frame exposure time) when both SVR and

SHR are set at “0”.

2. The camera works with the minimum shutter speed when SVR is set to 0 and this value is set

between 1 and 600.

3. The value replaces by 1923 automatically when the value set greater than 1923.

[Start line of the variable partial scanning]

Initial Data: PSR[150] = 0, Data Range: 0 to 2057

This sets the start line number of the variable partial scanning area.

Actual start line of the partial scanning = this value + 1

Notes:

1. The value replaces by 2057 automatically when the value set greater than 2057.

2. The camera works with full scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 2058.

Notes:

1. The value replaces by 2058 automatically when the value set greater than 2058.

2. The camera works with full scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 2058.

[Delay time for the trigger] Initial Data: DLY[70] = 0, Data Range: 0 to255

Sets the delay time from the trigger input signal to the start of the exposure.

Delay time (us) = 128 x CLK x DLY[70] = 2.000 (us) x DLY[70], where CLK = pixel clock

[CDS gain] Initial Data: PGA[70] = 0, data range: 0 to 255

Sets the CDS gain (programmable analog gain).

[Digital gain] Initial Data: The factory adjusted value, Data Range: 0 to 255

Sets the digital gain.

Output level = (input level – CLAMP[70] x 16 – (CDS_CLAMP_L[9..0] + CDS_CLAMP_R[9..0]) / 2) x

(1 + (DGB[7..0] + GOFS[7..0]) / 128) + CLAMP[7..0] X 16 +

[Gain offset] Initial Data: The factory adjusted value, Data Range: 0 to 255

[Clamp level] Initial Data: CLAMP[70] = 0, Data Range: 0 to 31

This sets the clamp level value of the black level.

Clamp level (Left) = CLAMP[7..0] x 16 + CDS Clamp (Left)

Clamp level (Right) = CLMAP[70] x 16 + CDS Clamp (Right)

The value replaces by 31 automatically when the value set greater than 31.

[Test pattern level] Initial data: 4095, data range: 0 to 4095
