FRAME IMAGE OUTPUT WITH STROBE LIGHT
A full frame image with vertical resolution of 485 lines (XC-ST50/ST30) or 575 lines (XC-ST50CE/ST30CE) can be obtained with a strobe light by firing the strobe when the exposure time of the two fields overlap.
� Timing and conditions
<Timing chart by restart/reset>
EXT HD
Continuous signal: 15.734 kHz (XC-ST50/ST30), 15.625 kHz (XC-ST50CE/30CE) Allowable frequency value ±1%
EXT VD
VD: XC-ST50/ST30 (1/60 sec), XC-ST50CE/30CE (1/50 sec) Four or more VD pulses are required.

Valid frame image
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 not to flash between VD and VD + 10H (XC-ST50/ST30)/ 16H (XC-ST50CE/ST30CE).
