Abstract: In an image processing apparatus, an image acquiring unit acquires a first image and a second image that form stereoscopic images. A first sub-image extracting unit extracts first sub-images from the first image. A second sub-image extracting unit extracts second sub-images from the second image. A matching unit matches each pair of the first and second sub-images to determine a degree of similarity therebetween. A similar sub-image setting unit sets the second sub-image having a highest degree of similarity to the first sub-image to be a similar sub-image to the first sub-image. A brightness comparing unit compares in brightness each pair of the first and second sub-images. The matching unit is configured to, if a result of comparison made by the brightness comparing unit between a pair of the first and second sub-images is out of a predetermined brightness range, exclude such a pair of the first and second sub-images.

Abstract: In a behavior recognition apparatus, a secondary informational item is generated for a corresponding target state of one or more than one target state extracted from each primary informational item acquired. The secondary informational item is represented by two different values, which express respectively (i) corresponding to the target state and (ii) not corresponding to the target state, the two different values being enabled to be added or subtracted. Further, a behavior vector is updated using a determination information group extracted by using a time window from a plurality of the secondary informational items in time series, and the driving behavior of the driver is recognized using the updated behavior vector.
