Provided are an image processing method, an image processing system, an image processing device and a computer program for detecting a detection object such as nares of the driver with a high degree of accuracy in, for example, a system using an in-vehicle camera which is mounted on a vehicle and takes an image of the face of the driver. A detection object is diversified by a variety of detection methods such as a method for detecting a plurality of locations in the vertical direction as candidates during image pickup of an image, detecting a range to be a candidate of a detection object on the basis of the brightness of a pixel for each of rows of pixels lined up in the horizontal direction corresponding to each detected location and specifying a detection object from candidates of a detection object on the basis of the length of the detected range.

Image object detection using separate ranges from both image detections

A system using an in-vehicle camera mounted on a vehicle for an image pickup object of the face of the driver, for: continuously taking an image of the image pickup object; performing manipulation, such as enlargement of an area including the image pickup object with a reference point being the center, for a second image based on image pickup after a first image, on the basis of the range of the image pickup object detected from the first image, the width of the facial contour of the driver, for example, and also a reference point such as the center of the face to be decided based on the location of the eyes and nose of the driver; and performing image processing, such as detection of the range of the image pickup object and decision of the reference point, for the manipulated second image.

Image processing method, image processing system, image pickup device, image processing device and computer program for manipulating a plurality of images

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.

Image processing system that detects an object by comparison of a difference between luminance of an illuminated and non-illuminated image

For example, a plurality of elliptical candidate areas that become candidate areas of detecting objects are set in an image, characteristic values such as average values of luminance of the pixels inside and outside the set candidate areas are compared, and a candidate area whose difference of the characteristic values is determined to be the maximum is detected as the area of the detecting object. In addition, central moment of the detecting object is calculated, and the inclination of the detecting object in the image is detected based on the calculated central moment. Further, two specific points such as eyes of the driver included in the detecting object are detected, and the inclination of the detecting object in the image determined by the detected two points is detected.

Image processing method, image processing system, image processing device, and computer program product

There are provided an image processing method, and an image processing system, an image processing device, and a computer program product capable of detecting a position of a fringe portion of a detecting object such as an outline of a face of a driver with high precision, even when a variation of illuminance occurs locally in a system using, for example, an on-vehicle camera mounted on a vehicle for imaging the face of the driver. Luminance of pixels arranged in a first direction such as a horizontal direction of an image is subjected to quadric differential, and data based on a quadratic differentiation result is accumulated in a second direction such as a vertical direction, and based on an accumulated result, a position in the first direction of the detecting object in the image is detected.

Image processing method, image processing system, image processing device, and computer program

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.

Alarm system, alarm control apparatus and alarm control program

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.
