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 the actual timing to start exposure after adding
trigger input, and for the actual timing to complete exposure at pulse width trigger shutter operation.
