Ricoh FV-L200B1 manual 27/32

Command No.	Command Descriptions
20H:	[Exposure time (H) of the electronic shutter] Initial Data: SVR[150] = 0, Data Range: 0 to 4095
SVR[70]	Sets the preset shutter speed (or CCD exposure time) for electronic shutter.
21H:
SVR[158]	The preset shutter speed is defined by the following formula.
	Exposure time (shutter speed) = SVR[150] x (1H	cycle time) + SHR[150] 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 306.
	3. The value is replaced with 4095 automatically when the value set greater than 4095.
22H:	[Exposure time (CLK) of the electronic shutter] Initial Data: SHR[150] = 0, Data Range: 0 to 1919
SHR[70]	Sets the preset shutter speed (or CCD exposure time) for electronic shutter.
23H:
SHR[158]	The previous section, the preset shutter speed is defined by the following formula:
	Preset shutter speed = SVR[150] x (1H cycle ti	me) + SHR[150] x (1CLK cycle time)
	Note 1: The camera works with the shutter off position (maximum frame exposure time) when both SVR and SHR
	are set at “0”.
	Note 2: The camera works with the minimum shutter speed when SVR is set to 0 and this value is set between 1
	and 306.
	Note 3: The value replaces by 1919 automatically when the value set greater than 1919
24H:	[Start line of the variable partial scanning] Initial Data: PSR[150] = 0, Data Range: 0 to 1235
PSR[7..0]	This sets the start line number of the variable partial scanning area.
25H:
PSR[158]	Actual start line of the partial scanning = this value + 1
	Note 1: The camera works with full scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 494.
	Note 2: The value replaces by 1235 automatically when the value set greater than 1235
26H:	[Effective line numbers in the variable partial scanning] Initial Data: PWR[150] = 494, Data Range: 0 to 1236
PWR[70]	This sets the number of the total effective lines (image height) in the variable partial scanning mode.
27H:
PWR[158]	Notes:
	1. The value replaces by 1236 automatically when the value set greater than 1236.
	2. The camera works with full scanning mode when the value of (PSR[ ] + PWR[ ]) is greater than 2058.
