EXT VD
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
Sample input timing chart 2
Continuous signal: 15.734 kHz (XC-EU50) Allowable frequency value ±1%,
15.625 kHz (XC-EU50CE) Allowable frequency value ±1%
VD interval (T): 262.5 H or more (XC-EU50) and less than 1 second (Recommended),
312.5 H or more (XC-EU50CE) and less than 1 second (Recommended)
Four or more VD pulses are required.

Frame image output with a strobe light
The factory setting for this camera is Frame
Accumulation. The images obtained when the normal
continuous shutter or trigger shutter is used are field
images (vertical resolution: 243 lines).
Using a strobe light and Restart/Reset mode, you can
obtain bright frame images by synchronizing any
strobe light. (Vertical resolution: 485 lines).
EXT HD
EXT VD
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
Avoid lighting the scene during the light-emitting inhibit zone defined below. (The field is transfered to the
storage area of the CCD, so it can be read out.)
Note
For best performance, it is recommended that you not flash between VD and VD + 10 H (XC-EU50)/16 H
(XC-EU50CE).
