Abstract: Provided is an apparatus and a method for inspecting a cloth piece, by which dirt and a tear can be reliably distinguished. The apparatus for inspecting a cloth piece includes: a first inspection camera 41 for picking up an image of reflected light from a cloth piece T passing through the dark color section 21; and a second inspection camera 42 for picking up an image of transmitted light through the cloth piece T passing through the transparent section 22. The dirt and the tear can be reliably distinguished by determining an area where the reflected light and transmitted light are both darker than a surrounding area to be dirt and by determining an area where the reflected light is darker than the surrounding area and the transmitted light is brighter than the surrounding area to be the tear.

Abstract: Provided is an apparatus and a method for inspecting a cloth piece, by which dirt and a tear can be reliably distinguished, and which have high accuracy to detect the dirt. The apparatus for inspecting a cloth piece includes: an inspection table 20 having a dark color section 21 and a light transmitting section 22; a first inspection camera 41 for picking up an image of reflected light from a cloth piece T passing through the dark color section 21; and a second inspection camera 42 for picking up an image of transmitted light through the cloth piece T passing through the transparent section 22. The dirt and the tear can be reliably distinguished by determining an area where the reflected light and transmitted light are both darker than a surrounding area to be dirt and by determining an area where the reflected light is darker than the surrounding area and the transmitted light is brighter than the surrounding area to be the tear.

Abstract: A mobile camera system is disclosed. The camera system connects plural camera apparatuses including at least first and second camera apparatuses mounted on a mobile body to one another and combines images photographed by the first and the second camera apparatuses, wherein reference data obtained by the first camera apparatus is transferred to the second camera apparatus via a camera control unit, signal processing is performed in the second camera apparatus on the basis of the reference data transferred to generate a corrected image, and an image from the first camera apparatus and the corrected image outputted from the second camera apparatus are combined to output a combined image.
