A scanning endoscope system includes: a light guiding section that guides illuminating light from a light source; a light collecting section that collects the illuminating light to make the illuminating light exit toward an object; an optical scanning section that drives one or more pairs of driving sections disposed at symmetrical positions across the light guiding section, thereby swinging the light guiding section such that positions in the object illuminated by illuminating light from the light collecting section form a trajectory according to a predetermined scanning pattern; a drive signal output section that outputs a first drive signal to one driving section of a pair of driving sections disposed along a predetermined axis direction in the optical scanning section, outputs a second drive signal to another driving section, and sets a center voltage value of the first drive signal and the second drive signal to a voltage value different from 0 V. |
