Multiple-shutter mode
Address:0x66, Bit:0, Value:1
In the multiple-shutter mode, video is output in sync with a MULTI signal from the external after the end of
exposure time.
・Valid only when the random trigger shutter mode is ON.
・MULTI signals can be input from the camera link I/F CC2.
・If exposure is executed several times before MULTI signal input, the images are output superposed.
・The exposure time is determined by the random trigger shutter mode setting and its determination method.
・The pulse width must be set to negative polarity and 1H (approximately 26.7μs) to 10 ms.
・FVAL is output in sync with the first LVAL after the end of MULTI signal input.

Notes on multiple-shutter:
An image has been stored to CCD device until a MULTI signal is inputted and it begins to read out
image after CCD is exposed. Therefore, an image may degenerate step by step when an image is stored
to CCD device for a long time.
And, Electric charge is superimposed in CCD device when the multiplex exposure. Therefore, CCD will
flood with electric charge when electric charge is over superimposed in CCD device. Consequently
vertical stripes noise will appear. At that time please stop using spotlight and dimmer for example close
the iris.
