ABSTRACT:
In an electronic endoscope system, an imaging device images a subject at a first frame frequency. A signal generating unit receives image signals of the subject imaged by the imaging device to generate signals of a standard TV system having a second frame frequency that is approximately n/m-fold (where, n and m are natural numbers, and n is unequal to m) of the first frame frequency. Then, a timing control unit synchronizes the first frame frequency of the imaging device with the second frame frequency using a predetermined timing signal output by the signal generating unit. The timing controller can also synchronize a first frame frequency of a color field sequential illumination unit with a second frame frequency using a predetermined timing signal.
