Changing Video Modes While Triggering
You can change the video format and mode of the camera while operating in trigger mode. Whether the new mode
that is requested takes effect in the next triggered image depends on the timing of the request and the trigger mode in
effect. The diagram below illustrates the relationship between triggering and changing video modes.
Figure 7.10: Relationship Between External Triggering and Video Mode Change Request
When operating in
Standard External Trigger (Mode 0)
or in
Bulb Shutter Trigger (Mode 1)
, video mode change requests
made before point A on the diagram are honored in the next triggered image. The camera will attempt to honor a
request made after point A in the next triggered image, but this attempt may or may not succeed, in which case the
request is honored one triggered image later. In
Overlapped Exposure Readout Trigger (Mode 14)
, point B occurs
before point A. The result is that, in most cases, there is a delay of one triggered image for a video mode request, made
before the configuration period, to take effect. In
Multi-Shot Trigger (Mode 15)
, change requests made after point A for
any given image readout are honored only after a delay of one image.
