<P>PROBLEM TO BE SOLVED: To provide an imaging device uninfluenced by illumination light from a light source in another imaging optical system when imaging an object image having a wide visual field by using a plurality of imaging optical systems. <P>SOLUTION: The plurality of imaging optical systems 2, 3 are arranged closely. Each imaging optical system is equipped with an illumination light source 10, an imaging lens system 12 and a linear imaging sensor 13. A light source driving circuit 21 is provided, and each light source is allowed to emit light successively with a prescribed frequency, and each linear image sensor executes a reading cycle and outputs a video signal during a light emission period of each light source. The video signal outputted from each linear image sensor is switched successively and outputted as a video output by a video output circuit 23 arranged on the subsequent stage of the linear imaging sensor 13. The video output circuit outputs the video signal from the linear image sensor in the imaging optical system after an emission cycle of the light source in the imaging optical system in the i-th number is finished. Since the video signal based on the electric charge accumulated during an emission period of the light source in another imaging optical system is discarded by performing switching control in this way, this device is not influenced even if the illumination light from the light source in another imaging optical system enters. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
