Abstract: In an object information generation system, an imaging unit is configured to capture a plurality of segment images respectively corresponding to a plurality of distance segments dividing a target space. In a signal processor, the object region extraction unit extracts, from a plurality of segment images, an object region that is a pixel region including an image of the object. An object information generation unit determines, for the object region, a window in which calculation-target pixels are cut out, and generates distance information of the object by calculation using information of a plurality of pixels in the window for two or more segment images.
