FRAME IMAGE OUTPUT WITH STROBE LIGHT
A full frame image with vertical resolution of 485 lines (XC-ST70) or 575 lines (XC-ST70CE) can be obtained with
a strobe light by firing the strobe when the exposure time of the two fields overlap.
• Timing and conditions
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.)
: For best performance, it is recommended not to flash between VD and VD + 10H (XC-ES50/ES30, XC-EI50/EI30)/
16H (XC-ES50CE/ES30CE, XC-EI50CE/EI30CE).

VD : XC-ES50/ES30, XC-EI50/XC-EI30 (1/60sec), XC-ES50CE/ES30CE, XC-EI50CE/XC-EI30CE (1/50sec)
Four or more VD pulses are required.
