1. A recognition dictionary creation apparatus, comprising:

  • an image capturing section configured to photograph a commodity to capture the image of the commodity;

    a measurement module configured to measure a distance from the image capturing section to the commodity photographed by the image capturing section;

    a specifying module configured to specify the commodity;

    a generation module configured to generate a quasi-commodity-image in a state in which the commodity is imaginarily moved away from the image capturing section to a given registration distance longer than the distance measured by the measurement module based on the image of the commodity photographed by the image capturing section;

    an after-generation extraction module configured to extract an appearance feature amount of the commodity from the quasi-commodity-image generated by the generation module; and

    an after-generation registration module configured to register, in a recognition dictionary in association with the registration distance data, the appearance feature amount extracted by the after-generation extraction module as the feature amount data of the commodity specified by the specifying module at the registration distance.
