Embodiment Construction

[0028] The scanning device of this embodiment adopts a general object recognition (generic object recognition: general object recognition) technology. General object recognition is a technique for recognizing the type of the object (target object) based on the image data captured by a camera. The computer extracts, from the image data, appearance feature quantities of items included in the image. Then, the computer checks the feature amount data of the reference image registered in the recognition lexicon file, calculates the degree of similarity, and recognizes the type of the article based on the degree of similarity. Techniques for recognizing items contained in images are described in the following documents.

Abstract

A scanner apparatus is disclosed and capable of guaranteeing the illuminance in a reading area at the same time of removing stray light. The scanner apparatus comprises a casing having an image capturing window on the front surface thereof; an image capturing section arranged inside the casing and configured to capture image of an object in a reading area invisibly formed outside the image capturing window of the casing; a plurality of lighting sections arranged inside the casing, and configured to irradiate light to the reading area, part of the light from the lighting sections being reflected on the inner surface of the image capturing window to become a stray light; and a shielding section configured to shield the stray light entering the image capturing section. The plurality of lighting sections mutually compensate the reduction in luminous intensity of the light from the lighting sections in the reading area caused by the shielding section.

Description

[0001] This application claims the priority of the Japanese application with the filing date of March 4, 2013 and the application number JP2013-042170, and cites the content of the above application. technical field [0002] The invention relates to a scanning device. Background technique [0003] In recent years, there has been a scanning device that uses an imaging element such as a CCD (Charge Coupled Device) sensor to extract the feature value of the object from the image data of the object such as a commodity, and compare it with a pre-prepared The feature quantities for verification are compared to identify the object. In such a scanner, generally, an illumination device is used to illuminate a reading area of ​​an imaging element to ensure illuminance. However, when an illuminating device is used, since stray light of reflected illuminating light is incident on the imaging element, it is necessary to provide an illuminating device in order to remove the stray light. ...
