IMAGE PROCESSING APPARATUS, METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

Extracting information corresponding to a three-dimensional object from an image captured by plural imaging apparatuses is implemented with a simple configuration and a simple 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 44, and a parallax correction control section 42 reads out a parallax amount corresponding to a Y coordinate value of image data for one line input from a pre-image processing unit 14 from the storage section 44 and outputs a selection signal to selectors 38 and 44 such that the output of one image data is delayed by the differential amount. A differential image generation unit 18 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.
