Abstract
A detecting and monitoring device which observes a detected object, includes a video camera with a solid state image pickup device including elements divided into two lines corresponding to an actuating timing of each line, a still video recorder for frame recording a picture image signal in an odd number field and picture image signal in a successive even number field as a picture image signal for one scope, a monitor, an emitting device for emitting a flash, and a strobo synchronizer so as to control the emitting device for emitting the flash in the even number field after an external trigger is input. The still video recorder records the odd field picture image signal and the even field picture image signal including the picture image illuminated under the flash. Thereby, the brightness of the picture image signal in the odd number field and the even number field are substantially equal to prevent flickering from occurring.
