The imaging apparatus further comprises a processing arrangement operable to reduce or increase the overall brightness of an image in dependence upon the overall brightness of the pre-enhanced image and the overall brightness of the preceding enhanced image, so that the change in the overall brightness (DC-level) between the enhanced image and the preceding enhanced image is decreased.
A vehicle surroundings monitoring apparatus is provided herein which is capable of determining an object type, particularly capable of determining an animal other than a human being among objects. The vehicle surroundings monitoring apparatus which monitors the surroundings of a vehicle by using an image captured by a camera (2R, 2L) mounted on the vehicle, including an object extraction process unit which extracts an image area of the object from the captured image (steps 1 to 6) and an object type determination process unit which determines the object type according to whether the image area of the object extracted by the object extraction process unit includes a first object area in which the ratio of widths in different directions is within a predetermined range and a plurality of second object areas located below the first object area and smaller in area than the first object area (steps 31 to 37).

A vehicle position determination system can determine a position of a first moving vehicle relative to at least one other moving vehicle and to non-moving objects. An information communication system transported by a first moving vehicle can be operable to receive from the at least one other moving vehicle an estimate of such moving vehicle's position relative to the first moving vehicle. Sensors of the first moving vehicle can be usable to obtain information relating to positions of other moving vehicles and non-moving objects in a vicinity of the first moving vehicle. A processor may then use the obtained information with the received estimate of the at least one other moving vehicle's position to make a first estimate of a position of the first moving vehicle relative to the other moving vehicles and non-moving objects.
—3 when a difference between an average luminance AVE_C of the reference mask area MASK_C and an average luminance AVE_L of the left-hand mask area MASK_L or a difference between the average luminance AVE_C and an average luminance AVE_R of the right-hand mask area MASK_R is equal to or greater than a predetermined level and which recognizes that the object type is “pedestrian” in the case where a plurality of second image portions are detected.
