Frame Image Output With Strobe Light - Sony XC-ST70 User Manual

XC-ST70/70CE

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
EXT HD
Continuous signal: 15.734 kHz (XC-ST70), 15.625 kHz (XC-ST70CE) Allowable frequency value 1%
EXT VD
Four or more VD pulses are required.
Strobe light
Exposure time for Odd field
Exposure time for Even field
Video output
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-ST70)/
16H (XC-ST70CE).
