The mobile phone 10 and the related information providing apparatus 20 are connected via a communication line 30 including a mobile communication network.

  The mobile phone 10 is a mobile communication terminal that performs wireless communication with a base station (not shown) that covers a wireless area in which the mobile phone is located and receives a call service or a packet communication service. The mobile phone 10 has a camera function. In the related information providing system 1 according to the present embodiment, the mobile phone 10 is used as a specific example of the mobile communication terminal. However, the specific example of the mobile communication terminal is not limited to this, for example, a simple mobile phone. (PHS) or a mobile communication terminal such as a portable information terminal (PDA) having a communication function. Moreover, an image capturing apparatus such as a digital camera that captures an image and an image transmitting apparatus for transmitting an image captured by the image capturing apparatus to the system side may be used.

  The related information providing device 20 is a server device that provides related information related to the determination target to the mobile phone 10 that has transmitted the attribute information of the determination target. Here, the discrimination target refers to a target that the user of the mobile phone 10 desires to discriminate. For example, a bronze statue, a building, a vehicle, animals and plants, food, multimedia data (for example, an image, a moving image, a voice), and the like. Is applicable. The attribute information of the discrimination target is information used to discriminate the discrimination target. For example, information on the discrimination target stored in the captured image obtained by capturing the discrimination target or the RF-ID tag attached to the discrimination target. In addition, information regarding a discrimination target embedded in the discrimination target with a digital watermark is applicable. In the present embodiment, a case will be described in which the discrimination target attribute information is a captured image of the discrimination target.

Information indicating the feature of the related information is stored as distribution 1 ″. Here, a specific example in the case of calculating the feature amount using, for example, RGB (red, green, blue) will be described below. First, each pixel constituting the discrimination target image included in the related information is digitized by RGB (for example, 0 to 255.) Next, each numeric value of RGB obtained for each pixel belongs to the numeric value. A frequency distribution table for each RGB is created by allocating to a predetermined class (for example, 1 to 8), whereby the color feature amount of the entire image to be discriminated is calculated. Feature quantities are color features (for example, , RGB), for example, calculation using sound characteristics (for example, frequency band) and taste characteristics (for example, levels of sourness, saltiness, sweetness, bitterness, umami) For example, “2004/09/30” is the date when the related information related to the discrimination target was last updated (registered / changed / deleted).

For example, when the feature amount is calculated using an RGB frequency distribution classified into 8 classes. , R (8 classes), G (8 classes), and B (8 classes), the feature amount is represented by all 24 dimensions, so V (number of vector dimensions) = 24. “X (vector)” is a vector variable representing the feature amount of the captured image to be determined. “Θ (vector)” is a vector variable that represents an average value of feature quantities for each piece of related information. Specifically, with reference to FIG. 3, “θ (vector)” is an average value of “RGB frequency distribution 1” to “RGB frequency distribution 4” when the related information is “Hachiko”, for example. Thus, when the related information is a “moyai image”, the value is “RGB frequency distribution 5”. Further, “l” is a variable indicating that the related information currently being calculated is the “l” -th related information of L types of related information in total. Note that the method for obtaining related information having a feature amount similar to the feature amount of the captured image is not limited to the method using the above-described equation (1), and includes, for example, Fisher's linear discriminant method, subspace method, projection distance method, Neural networks, LVQ (Learning Vector Quantization), SVM (Support Vector Machine), kNN (k-Nearest Neighbor), Bayesian methods, NB (Naive Bayes), and other methods may be used.
