Cautions for Trigger Shutter Modes
Caution 1: When the next trigger is input before the completion of video signals output for the prior
trigger, the images could be improper.
Caution 2: Smear or blooming could occur when strong incident light is extensively illuminated, with
setting the electric shutter at high speed. To avoid this smear or blooming, lower the volume of
incident light or use a stroboscopic light source to control the light volume.
Caution 3: Please refer to the exposure timing chart below for 30fps mode for the actual timing to start
exposure after adding trigger input, and or for the actual timing to complete exposure at pulse width
trigger shutter operation.
