Information processing system, method of information processing, and program

A method of information processing executed in an information processing system, including a server device, and an information processing device communicable with the server device, the information processing device acquiring a plurality of images imaged by an imaging device included in a vehicle, the method comprising steps, executed by one of the information processing device or the server device, of:

• determining a rain gear usage rate from the acquired plurality of images;
• and
• outputting, when a determination is made that the rain gear usage rate increases by a prescribed value within a prescribed time interval, a notification that indicates an increase in intensity of rainfall.

A non-transitory computer readable medium having instructions stored therein, which when executed by a processor in one of an information processing device and a server device, the information processing device being communicable with the server device in an information processing system, the information processing device acquiring a plurality of images imaged by an imaging device included in a vehicle, causes the processor to execute the steps of:

• determining a rain gear usage rate from the acquired plurality of images;
• and
• outputting, when a determination is made that the rain gear usage rate increases by a prescribed value within a prescribed time interval, a notification that indicates an increase in intensity of rainfall.
