Extracting information corresponding to a three-dimensional object from an image captured by plural imaging apparatuses is implemented with simple configuration and processing. Parallax information representing a parallax amount in the X direction of a pair of images captured by a pair of imaging apparatuses disposed at different horizontal positions is stored in a storage section, and a parallax correction control section reads out a parallax amount corresponding to a Y coordinate value of image data for one line input from a pre-image processing unit from the storage section and outputs a selection signal to selectors such that the output of one image data is delayed by the differential amount. A differential image generation unit calculates an absolute value of the differential of the pair of input image data for each pixel and outputs the result as a differential image for detecting the three-dimensional object. |
