A generating unit generates two-dimensional distribution information indicating a two-dimensional distribution of an object, in which an actual distance in a horizontal direction, a distance value indicating a distance in a depth direction, and a frequency value indicating an occurrence frequency of a distance value are related by using for example a disparity image. A labeling unit conducts a labeling process by conducting search on the two-dimensional distribution information multiple times, detecting a pixel having the frequency value that is more than a predetermined threshold during each search, and assigning a label that corresponds to the number of times of search. During this labeling process, a labeling process is conducted by selecting a pixel having a frequency value more than the above-described threshold from pixels that abut a pixel being searched in a search direction. A labeling process is selectively performed on pixels, whereby a labeling process may be conducted in accordance with the shape of an object. Objects are detected from two-dimensional distribution information by regarding pixels with the identical label assigned thereto as pixels of an identical object so that objects may be detected in a separate manner with accuracy.
