  • Page 17: Trigger Control

    Trigger Control Free run/trigger mode Free run The camera operates without a trigger signal and performs image output operation continuously after the shutter (exposure) is finished. The horizontal and vertical timing signals are generated within the camera. During free-run operation, image pickup timing cannot be controlled. In free-run operation, adjustment is made automatically to achieve the maximum frame rate according to the shutter setting.
