Abstract: A window glass system includes a window glass to be attached to a moveable body, an anti-fog film to be provided on a cabin-side surface of the window glass, a temperature sensor configured to detect a glass temperature of the vehicle cabin-side surface of the window glass, a temperature-and-humidity sensor configured to detect a temperature and a humidity of a cabin of the moveable body, drying means configured to vaporize water attached to the anti-fog film, and a processing circuitry configured to estimate a time duration Ts, based on the glass temperature detected by the temperature sensor and the temperature and the humidity of the cabin detected by the temperature-and-humidity sensor, the time duration Ts being a duration of time until fogging occurs on the anti-fog film, and activate the drying means based on the time duration Ts.
