Example of Timeout in Rapid Capture Mode
Since examples 5 is in Rapid Capture mode, the cameras will continue to switch until the
Number Of Captures setting has been met.
Example # 5
Time Between Captures = 0
Capture Mode: Dual Camera
Number of captures = 6
Internal camera timeout = 170mS
External camera timeout = 160 mS
Note: The third and fifth captures were never completed since the active camera’s timeout occurred dur-
ing the capture. When this occurs the capture is aborted and the active camera is switched.
Example of Timeout in Continuous Capture Mode
Continuous Capture mode is a little more involved due to the double buffering. The cam-
eras will continue to switch for the duration of the read cycle in a double-buffered format,
so that we start processing the first image while we are capturing the second. The third
image will then start when both the first one is completely processed and the second is
completely transferred.
