A computer implemented information processing method includes acquiring a first photographed image that represents an inside portion of a vehicle, identifying a driver who drives the vehicle from the first photographed image, acquiring driver information that indicates at least one of an attribute of the identified driver and a driving history of the identified driver. Then the method determines whether or not the identified driver satisfies a condition of experienced driver using the driver information. Finally the method decides a threshold value that is used for detection of occurrence of an event to be a trigger of photographing or recording of a second photographed image which represents an outside portion of the vehicle based on a result of the determination.
