Abstract: The invention in this application is an information acquisition/identification system provided with an image-feature storing unit, an extracting unit, an acquiring unit, and an identifying unit. The image-feature storing unit stores image features of texture patterns formed on components or products. The extracting unit extracts an information-label image and a texture-pattern image from a taken image containing at least the following: an information label that displays information regarding a component, a product, or a product comprising said component; and a texture pattern formed on said component or product. The acquiring unit acquires, from the extracted information-label image, the aforementioned information regarding the component or product. The identifying unit identifies the component, product, or component-comprising product by matching image features of the extracted texture-pattern image against the image features stored by the image-feature storing unit.

Abstract: An image capturing device, configured to illuminate an object by an illumination means and capture reflected light from the object as a reflection image by a capturing means, includes an irradiation angle range determination means. The irradiation angle range determination means determines, assuming that a group of pieces of unevenness existing at the same position on the surfaces of a plurality of individuals of an object is an unevenness group, an irradiation angle range for irradiating the object by the illumination means, on the basis of a statistic value of the inclination angles of the unevenness group in which variations in the inclination angles of the unevenness between individuals is larger than other unevenness groups, among the plurality of unevenness groups.

Abstract: When there is an image component common to multiple registered images, the accuracy of individual identification lowers. A decision unit decides, for each partial area, the degree of effectiveness relating to calculation of a score representing a similarity between a registered image obtained by capturing an object to be registered and a collated image obtained by capturing an object to be collated, based on whether or not the partial area contains an image component common to multiple registered images obtained by capturing multiple objects to be registered. A calculation unit calculates the score based on image components contained in the registered image and the collated image and on the degrees of effectiveness.
