Abstract
A driving assistance device includes a camera, a moving object detector, a candidate reflection region detector, a predetermined position brightness detector and a cause determiner. The moving object detector and the candidate reflection region detector sets a detection region for detecting, from image data captured by the camera, existence of an adjacent vehicle in an adjacent lane. The predetermined position brightness detector detects a candidate light projecting object which projects light with brightness equal to or higher than a predetermined threshold value. The cause determiner determines whether or not there exists a candidate light projecting object which indicates existence of the adjacent vehicle in the detection region.

10. A driving assistance device that provides a driver with various pieces of information from a result of capturing images around an own vehicle, comprising:
-
an image capturing unit mounted on the own vehicle to capture images behind a side of the own vehicle; a detection region setter that sets a detection region for detecting, from image data captured by the image capturing unit, existence of an adjacent vehicle in an adjacent lane; a candidate light projecting object detector that detects a candidate light projecting object which projects light with brightness equal to or higher than a predetermined threshold value; a cause determiner that determines whether or not there exists a candidate light projecting object which indicates existence of the adjacent vehicle in the detection region set by the detection region setter; and an information provider that provides the driver with information of existence of the adjacent vehicle, if it is determined by the cause determiner that light is projected from the adjacent vehicle, wherein the cause determiner determines whether or not the light is projected from the adjacent vehicle by detecting an image capturing position of the candidate light projecting object detected by the candidate light projecting object detector. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A driving assistance method that provides a driver with various pieces of information from a result of capturing images around an own vehicle by an image capturing unit, comprising:
-
an image capturing step of capturing images behind a side of the own vehicle by the image capturing unit mounted on the own vehicle; a detection region setting step of setting a detection region for detecting, from image data captured in the image capturing step, existence of an adjacent vehicle in an adjacent lane; a candidate light projecting object detecting step of detecting a candidate light projecting object which projects light with brightness equal to or higher than a predetermined threshold value; a cause determination step of determining whether or not there exists a candidate light projecting object which indicates existence of the adjacent vehicle in the detection region set in the detection region setting step; and an information providing step of providing the driver with information of existence of the adjacent vehicle, if it is determined in the cause determining step that light is projected from the adjacent vehicle, wherein the cause determining step determines whether or not the light is projected from the adjacent vehicle by detecting an image capturing position of the candidate light projecting object detected in the candidate light projecting object detecting step.

19. A driving assistance device that provides a driver with various pieces of information from a result of capturing images around an own vehicle, comprising:
-
an image capturing means mounted on the own vehicle to capture images behind a side of the own vehicle; a detection region setting means that sets a detection region for detecting, from image data captured by the image capturing means, existence of an adjacent vehicle in an adjacent lane; a candidate light projecting object detecting means that detects a candidate light projecting object which projects light with brightness equal to or higher than a predetermined threshold value; a cause determining means that determines whether or not there exists a candidate light projecting object which indicates existence of the adjacent vehicle in the detection region set by the detection region setting means; and an information providing means that provides the driver with information of existence of the adjacent vehicle, if it is determined by the cause determining means that light is projected from the adjacent vehicle, wherein the cause determining means determines whether or not the light is projected from the adjacent vehicle by detecting an image capturing position of the candidate light projecting object detected by the candidate light projecting object detecting means.
