5.2.9 Selection of the Frame Time Standard (FRM TIME)
When setting the frame counter display to a relative time or an absolute time, the time standard can be
selected.

Trigger Signal Input Time
Using the trigger signal input time during recording as the standard, the time corresponding to
the recording speed is calculated for the next frame (Figure 5-16). The advantage of this setting
is that it is easy to make the time between each frame uniform.
However, the frame time cannot be displayed with EST synchronized signal recording.

Mid-point of the Exposure Start and End Times
The mid-point of the sensor exposure start and end time becomes the frame time (Figure 5-13).
If using the time stamp function, since the image and the time information is saved in the
memory, the frame time for the EST synchronized signal recording is also displayed.
However, if the automatic exposure function (AE) is set, the time between each frame is not
uniform.
