Abstract
A detection system of vehicle interior condition including 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 for photographing an occupant and/or an object on the seat upon each illumination of the illumination unit, and a control processor for comparing a plurality of images photographed by the imaging unit and also for generating information indicative of a condition of the occupant and/or the object on the basis of a comparison result of the image comparator.
Claims20
A detection system of vehicle interior condition comprising:
- 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 at different timings during a predetermined period;
- an imaging unit for photographing an occupant and/or an object on said seat upon each illumination of said illumination unit;
- and
- a control unit having an image comparator for comparing a plurality of images photographed by said imaging unit and also having an information generator for generating information indicative of a condition of said occupant and/or said object on the basis of a comparison result of said image comparator.
A detection device of vehicle interior condition comprising:
- an input unit for receiving a signal from an imaging unit which illuminates a plurality of mutually different illumination regions including at least one seat of a vehicle and a surrounding region thereof at different timings during a predetermined period, and also for receiving a signal a signal from an imaging unit which photographs an occupant and/or an object on said seat upon each illumination of said illumination unit;
- an image comparator for comparing a plurality of said images photographed by said imaging unit;
- an information generator for generating information indicative of a condition of said occupant and/or said object on the basis of a comparison result of said image comparator;
- and
- an output unit for issuing the information generated by said information generator.
A detection method of vehicle interior condition comprising the steps of:
- illuminating a plurality of mutually different illumination regions including at least one seat of a vehicle and/or a surrounding region thereof at different timings during a predetermined period;
- photographing the occupant and/or the object on said seat upon each illumination;
- comparing a plurality of said photographed images;
- and
- generating information indicative of a condition of said occupant and/or said object on the basis of a comparison result of said comparison step.
