摘要
The nearby region image extraction device according to the present invention ensures robustness during outdoor usage and acquires nearby region images at the field rate. This device comprises a color camera for taking color moving images; an infrared light source for irradiating a nearby object OB with infrared light; an infrared camera for alternately acquiring a lit infrared image and an unlit infrared image; an absolute value differential image acquiring section for acquiring an absolute value differential image for the lit infrared image and unlit infrared image; a nearby region image extraction section for extracting a nearby region image from the absolute value differential image; and an object image extraction section for extracting an object image that represents the nearby object from the nearby region image.
