Using an on-vehicle camera mounted on a vehicle to view the face of a driver as an imaging object, an image processing system judges the presence/absence of the imaging object in the image. An average luminance of an image when light of a particular wavelength is irradiated in an imaging direction is compared to an average luminance of an image imaged when no light is irradiated. When the difference between the average luminance values is equal to a reference value or less, it is judged that the imaging object is absent in the image by imaging.

An alarm system includes a miniature camera (), a loudspeaker (), a vehicle speed sensor (), a longitudinal G sensor (), a lateral G sensor () and an on-vehicle unit (). A CPU () of the on-vehicle unit () executes respective programs ()&#x2013;() in a ROM (), thereby outputting, if a traveling distance during a period for which a driver D continues to take an abnormal behavior exceeds a predetermined value when a traveling state of an automobile is kept stable, an alarm corresponding to a magnitude of the excess over the predetermined value from the loudspeaker (). The alarm system is thus configured and is therefore capable of exactly outputting the alarm when a danger actually rises.

Obtaining an image frame picked up by a camerathrough a cable C, a CPUof a computeridentifies an eye area in the image frame and stores a template indicating the identified area as a tracking template. Moreover, the CPUidentifies an eye area in an image frame to be obtained subsequently on the basis of the tracking template, and calculates a correlation value between the template of the identified area and the tracking template. Furthermore, when the calculated correlation value is larger than a threshold stored in an HDin advance, the CPUstores the template indicating the identified area in the RAMas a tracking template, so as to update an eye area in a series of two image frames in chronological order.

An image sensor section and a millimeter-wave sensor section separately detect objects. A sensor matching section determines whether the objects detected by the image sensor section and the millimeter-wave sensor section are one and the same object. If the objects are one and the same object, the sensor matching section estimates a position of the obstacle after a certain period. A collision prediction section determined whether there is going to be a collision between the vehicle and the objectfrom the position estimated by the sensor matching section.
