Abstract
A detection system of vehicle interior condition includes an illumination unit for illuminating a plurality of mutually different illumination regions including at least one seat of a vehicle and a surrounding region thereof so as to have different illumination time durations shifted by a predetermined time. An imaging unit photographs an occupant and/or an object on the seat upon each illumination of the illumination unit. A control processor compares a plurality of images photographed by the imaging unit, and generates information indicative of a condition of the occupant or object, based on the result of the comparison.
