Polaroid CSGS15BC23, CSGX36BC3 Exposure time depends on the normal shutter speed setting

(6) Electronic shutter mode switching

You can switch the shutter modes by adjusting the setting value of the command status register of the camera via the Gigabit Ethernet. The setting method has two kinds of the following.

- Normal shutter

Performs exposure control via the internal synchronization signal.

PRESET mode	1/100, 1/250, 1/500, 1/1,000, 1/2,000, 1/4,000, 1/10,000
	and 1/20,000s
Absolute value setting	Any value is set up in 32-bit floating point form within the range
	of 1/20000s to 2s

- Random trigger shutter:

Random trigger shutter can capture images at any timing using the external trigger signal and soft trigger input. It is effective for image input of moving objects and obtaining images of the same timing using multiple cameras. But there is an exposure delay time.

The random trigger shutter of this camera can be operated in two types of mode. How to determine the exposure time differs depending on the mode.

Fixed mode:	The exposure time depends on the normal shutter speed setting.
Pulse width mode:	The exposure time depends on the pulse width.

Notes on long exposure:

-When you set the exposure time longer than approximately 1 second, white spots and the unevenness in highlight portion might occasionally be observed on screen. This phenomenon is due to the characteristics of the CCD image-pickup device, and do not reflect performance error in the pickup device or CCD Camera itself.
