8.5 OPTIONS
8.5.1 What non-standard modes of integration are available ?
The three non-standard modes of integration are:
• Electronic Shuttering (1/1000 sec and 1/2000 sec)
• Pulse driven Integration Mode
• “N” field Integration Mode (user specified value of “N”)
8.5.2 What is the difference between electronic shuttering and pulse driven
integration ?
Electronic Shuttering is used for integration periods less than 1/1000 sec. The integration takes
lace within the vertical blanking interval and the sync and timing of the camera are un-disturbed.
The Pulse driven Integration Mode is used for integration periods greater than 1/1000 sec. Since
his is greater than the vertical blanking period, the video timing is usually disturbed.
8.5.3 Do I need a frame grabber for non-standard integration modes ?
For the Electronic Shuttering mode, the image raster on a monitor is quite stable. A frame
grabber may be used but is not mandatory.
For the Pulse driven Integration Mode, a frame grabber is usually mandatory.
8.5.4 What is the image format (size) during electronic shuttering and pulse driven
integration ?
Since only one field results from each integration on the CCD, the image format is 755(H) X
242(V)
8.5.5 Can I use genlock/asynchronous reset & electronic shuttering simultaneously
?
Yes ! Both Genlock & the asynchronous reset mode work well with electronic shuttering.
8.5.6 What is genlock and how does it work ?
Genlock is an option that is available on all models. When it is installed, a camera can be
"locked" to an external source of sync or video.
See section 5.3.3 for more details.
