Abstract
An endoscope system wherein a first electronic endoscope apparatus and second electronic endoscope apparatus are used as combined characterized in that a field sequential illuminating system forming a first electronic endoscope apparatus and a field sequential illuminating system forming a second electronic endoscope apparatus are synchronized by a synchronizing signal to make an illumination so that neither apparatus may produce such deterioration of the picture quality as the break of the color balance and a smear or the like.
