3.15. The size of the Video Preview has changed, how do I go about changing it back?

If yourself and your colleagues all use the same user account its possible that someone has changed one of the following settings:

Binning

You will find this in the Device Controls when using the Video Preview.

Binning is the combination of 2 or more camera pixels. If you still see the same area of your sample but the image is a different size perhaps the binning has changed. As you increase the binning level the size of the Video Preview will get smaller. Make sure you are using the same binning level that you were previously using.

Crop Video

You will find this by going to the Video menu and Seleting Crop Video.

You can choose from a range of sizes including Full Frame. Smaller sizes will use only part of the CCD. To undo the crop and restore the Video preview to full either select Full Frame or select the Crop tool:

then click anywhere outside the crop boundary.

CCD active area

You will find this by going to the Video menu and selecting CCD Active Area...

Its possible that another user has set margins making the overall image smaller. Some combinations of optical components do not generate an image to fill the full field of view. The CCD active area allows you to use margins to exclude unwanted areas. In the CCD active area window click the Default button to reset the margins to 0.
