Camera Setup

This command sets the type of video system used to display a live video feed of the microscope’s field of view in the application window.

Stereo Investigator displays the live image in a non-destructive overlay: Each pixel of a particular color, referred to as the key color, is replaced by live video. This lets you trace, count, and normally operate your computer while the live video updates in Stereo Investigator.

Stereo Investigator supports the following:

The video camera/frame grabber setup generally displays live video at a fast rate but lower resolution. However, digital cameras typically update live video at slower rates, but have substantially higher resolutions.

  • Select Fit video in Window to reduce the size of the video so that the entire video is visible within the tracing window.

When should you disable this option?

When the video resolution is lower than your monitor resolution, and the entire video is displayed in the top left of the tracing window with black regions bordering the bottom and right of the video.

  • When enabled, Fit Video in Window will attempt to fill the tracing window with the video by stretching the video. make sure to uncheck the box.
