An apparatus comprising: a processor; and a memory storing thereon a computer program, which when executed by the processor, causes the processor to perform operations including: obtaining map information and a time series of images captured by an image capturing apparatus mounted in a vehicle; detecting a traffic mirror located near the vehicle; generating driving assist information; and outputting the driving assist information; characterized in that the map information includes additional map information indicating at least one of a traffic accident, a traffic jam, a road construction, a road surface condition, and weather on a map; the traffic mirror is detected in the time series of images by using the position of the vehicle and the installed place of the traffic mirror indicated by the map information; and further characterized by the operations further including: determining characteristics of the installed place of the traffic mirror by using the additional map information for an area near the traffic mirror, and the time series of images comprising the traffic mirror, wherein the characteristics include a state of a road at the installed place of the traffic mirror or a passage state of an object at the installed place of the traffic mirror, wherein the passage state of the object indicates a degree at which people or vehicles enter or exit the area near the traffic mirror, wherein the generating of the driving assist information is based on the determined state of the road or the determined passage state of the object; and wherein the processor is further caused to generate and output vehicle control information for causing the vehicle to be temporarily stationary until a moving object reflected in the traffic mirror in at least one image in the time series of images becomes visible directly from the vehicle or in the traffic mirror, in a case where the moving object is not recognized in an image subsequent to the at least one image in the time series of images. a processor;
