(7) High-speed draft readout mode   

By thinning out vertical lines, it can be read all effective area at high-speed frame rate. 

* As for CSGV90CC3 (VGA), this mode supports a fault.

(8) Image resending control 

As the resending control of the image, this camera resends the packet which suffered a loss. 

 

(9) 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 three kinds of the following. 

- AE (Auto Exposure) 

The brightness is adjusted automatically by the average photometry of the entire screen. 

Effective range 

 

1/20000s to Setting value of the frame rate

Exposure level  

 

-1EV to +1EV (1/3EV step) 

By combining this mode and AGC (ALC mode), it can follow so much to brightness change of subject. 

- Normal shutter 

Performs exposure control via the internal synchronization signal. 

PRESET setting: 

 

1/100s, 1/250s, 1/500s, 1/1000s, 1/2000s , 1/4000, 1/10000,   

and 1/20000s 

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. 

- It is outside a guarantee when having set it as this mode, and a normal shutter is turned off. 

Please be sure to turn on a normal shutter. 

 

- 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.
