3.5 Start!/Stop!... A Toggle Menu Action Item

Activating the Start! menu item will cause the LBA-PC to start collecting and processing frames of data. The source of the data frames can be either live video input to the Frame Grabber card, if installed, or from previously stored data files. Refer to the Capture Method section for source selection.

Activating the Stop! menu item will cause the LBA-PC to stop collecting and processing new data.

During Ultracal operations, the Stop! menu item can also be used to abort the calibration process. An abort will cause the last previously generated (if any) Ultracal conditions to be restored.

3.6 Ultracal! Menu Action Item

Ultracal is a trademark of Spiricon Inc.

Ultracal processing is protected under United States Patent Nos. 5,418,562 and 5,440,338.

Activating the Ultracal! menu item will cause the LBA-PC to begin an automatic camera calibration cycle. The results of this operation will be to store a calibration frame that will be used to preprocess all data frames newly acquired from the Frame Grabber card.

Note: The Ultracal process is only applied to newly acquired data frames; not to data that was acquired prior to an Ultracal execution; nor is it applied to data from a data file. If you execute a Post Processing operation, Ultracal will be turned OFF at the start of Post Processing, and remain OFF after it’s completion.

The status of the Ultracal condition is visible in the Ultracal Enunciator shown here and at the bottom of the LBA-PC’s main display screen.

If the color of the Ultracal Enunciator is: GRAY, Ultracal processing is turned OFF.

GREEN, Ultracal operation was successful and is OPERATING.

RED, Ultracal processing has been DISABLED because something caused the calibration to become invalid.

Hint: Just because the Ultracal enunciator is GREEN it doesn’t mean that all is well. Camera baselines drift with temperature and over time. Therefore it is a good practice to re-Ultracal! just prior to collecting important data.
