Grab: frame grabber software on Lucille (Imager Dark)

Grab is a very easy program to use. The interface is very stright forward and is explained in the grab interface HTML document.

The program provides the user with two windows, the interface and the video window. Examples of both of these can be found in the grab interface HTML document. The program allows one to grab one or more frames of video from lucille's video inputs at various resolutions.

In order to run grab /imager/local/bin must be in your path. If it isn't, change to that directory and type ./grab.

If you do not know how to set up the equipment then see the Frame grabbing database document.

Trouble Shooting

If you have set everything up as is explained in the Frame grabbing database and it is still not working here are a few things to check for:
  1. That the outputs of the frame generating device (i.e. Laser VideoDisk, VCR , JVC CCD camera, etc... ) are going into the correct inputs. (It sounds silly but it is a common enough mistake)

  2. If you are using the Vid/IO Box to change the video format to RGB for Lucille's inputs make sure that the source select switch is set to video (for composite/video in) or S-video (for SVHS video in).

  3. One other thing to check is the setting of the termination switches. This will affect the quality of the colour one gets. Generally speaking they should be set to 75 Ohms (i.e. terminated.) For an explanation of the function of the termination switches see Termination switches.

The explanation of the grab interface follows this link.
