Trigger Control; Free Run/Trigger Mode / Ptp (Ieee1588) - Sony XCG-CG160 Technical Manual

Trigger Control

Free run/trigger mode / PTP (IEEE1588)

Free run
The camera operates without a trigger signal and performs the video output operation continuously after the shutter
(exposure) is finished. The horizontal and vertical timing signals are generated within the camera. During the free-run
operation, image pickup timing cannot be controlled. In the free-run operation, the adjustment is made automatically to
achieve the maximum frame rate according to the shutter setting.
Trigger mode
Exposure is started by detecting the externally input trigger signal. When ExposureMode is 0, exposure is started by
detecting the rising or falling edge of the trigger signal and the trigger edge detection (exposure is performed based on
the set shutter value) is performed. When ExposureMode is 1, the trigger width detection (exposed for the period of the
trigger signal width) is performed.
