6.4.3. Restart Continuous Trigger mode

The RCT mode is in principle the same as normal continuous mode. The difference is that an external trigger pulse will immediately stop the video read out and reset and restart the vertical timing. After a fast dump read out, a new triggered exposure is started and read out as normal. The fast dump read out is performed with a speed 18 times faster for single output, and 10 times faster for dual output. If no further trigger pulses are applied, the camera will continue in normal mode. This fast dump read out has the same effect as “smearless read out”. Smear over highlighted areas are reduced for the triggered frame.

The restart continuous trigger mode makes it possible to use a lens with video controlled iris in intelligent traffic surveillance applications.

To use this mode:

 

 

Set function:

Trigger mode “Restart continuous trigger”

TR=2

 

LVAL synchronous accumulation

LS=0

 

Shutter mode “Normal” or “Programmable”

SM=0, SM=1

 

“Shutter Speed”

SH=0 through 9

 

“Programmable exposure”

PE=1 through 1216

 

Scanning format

SC=0 through SC=4

 

Output select

OS=0, OS=1

 

Polarity and other functions

 

Input:

Ext. trigger to Camera Link or pin 10 on 12-pin connector.

Important notes on using this mode.

•The duration of the trigger should be >2LVAL to <3FVAL.

•A new trigger must not be applied before the triggered data is read out.

•1LVAL = 47.9 ∝sec (single). 27.3 ∝sec (dual).

•The time for the fast dump read out (smearless) is 3.3 msec.

For horizontal timing refer to 6.2.3. through 6.2.6. (Fig.17. through fig. 20.) For LVAL synchronous accumulation refer to 6.2.7. and 6.2.8. (Fig. 21. fig. 22.)
