In a device that removes water droplets on the mirror surface by driving a vibrator provided on the back surface of the mirror, a first frequency band for atomizing and scattering large water droplets and a first frequency band for atomizing and scattering small wave droplets are used.
A water droplet removing device comprising: an oscillation circuit that causes a vibrator to oscillate with a second frequency band to be scattered; and a sweep circuit that sweeps both of the frequency bands. 2. The water droplet removing device according to claim 1, wherein the oscillation circuit has a programmable counter that repeatedly sweeps the first frequency band n 1 times and then repeatedly sweeps the second frequency band n 2 times. 3. The water droplet removing device according to claim 1, wherein the oscillation circuit has a programmable counter that repeatedly sweeps the first and second frequency bands alternately.
