In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a mobile phone 10 that is an evaluation information generating apparatus according to the present embodiment. The mobile phone 10 is a device that is carried (possessed) by a user and has a communication function such as mobile communication. As shown in FIG. 1, a mobile phone 10 according to the present embodiment can communicate with a product information providing server 20 via a network N such as the Internet or a mobile communication network, and transmits and receives information to and from each other. be able to. The product information providing server 20 is a device that transmits product evaluation information in response to a request from a communication device such as the mobile phone 10. The merchandise information providing server 20 is configured as a Web server, for example, and transmits evaluation information as Web content.

  The evaluation information is information indicating various user evaluations on the product to be evaluated. Specifically, for example, it is represented by a numerical value in three stages. The product to be evaluated may be anything that can be evaluated by the user, in addition to items used by general users (for example, food such as confectionery), stores and services used by the user, and the like. . By referring to the evaluation information, the user can know what evaluation the product is receiving. The mobile phone 10 is a device that generates evaluation information indicating an evaluation on a product to be evaluated by a user of the mobile phone 10 to be transmitted to the product information providing server 20. Specifically, how evaluation information is generated will be described later.

  FIG. 2 shows a hardware configuration of the mobile phone 10. As shown in FIG. 2, a mobile phone 10 includes a CPU (Central Processing Unit) 101, a RAM (Random Access Memory) 102 and a ROM 103 (Read Only Memory) which are main storage devices, an operation unit 104, a wireless communication unit 105, a display. 106, antenna 107, and the like. Further, the mobile phone 10 includes a camera 108 in addition to the hardware described above. By operating these components, each function of the cellular phone 10 described later is exhibited.

  Subsequently, functions of the mobile phone 10 according to the present invention will be described. As shown in FIG. 1, the mobile phone 10 includes an imaging unit 11, an evaluation target information extraction unit 12, an evaluation information extraction unit 13, and an output unit 14. In addition to the above, the mobile phone 10 also has a function as a normal mobile phone (not shown).

  The imaging unit 11 is an image input unit that inputs an image. The image is for generating evaluation information (evaluation information is generated based on the image). The imaging unit 11 captures an image with the camera 108 provided in the mobile phone 10 and inputs the captured image. The imaging unit 11 outputs the input image to the evaluation target information extraction unit 12 and the evaluation information extraction unit 13.

  Here, an image input by the imaging unit 11 will be described. From this image, the evaluation object information indicating the evaluation object and the evaluation information indicating the user's evaluation for the evaluation object are extracted. The evaluation target information is, for example, the product name of the product to be evaluated or the store name of the store. Also, the evaluation information is a numerical value indicating how much evaluation is made, for example, among three levels of evaluation.

  As shown in FIG. 3, a first area 51 and a second area 52 are set in an image 50 input by the imaging unit 11. The first area 51 is an area for extracting evaluation target information. The first area 51 is an upper rectangular area in the image 50. As shown in the imaging example of FIG. 4, the image 50 is captured so that evaluation target information such as the product name of the package 61 of the product to be evaluated is reflected in the first region 51.

  The second area 52 is an area for extracting evaluation information. The second area 52 is a lower rectangular area in the image 50. As shown in the imaging example of FIG. 4, the image 50 is captured such that the second region 52 is in a state corresponding to the evaluation information. Specifically, in the present embodiment, the evaluation information is determined by how many fingers 62 of the user's hand appear in the second region 52 of the image 50. That is, the evaluation information is information indicating the number of fingers of the user's hand that are reflected in the second area 52. Therefore, when the image is captured, the user puts out the finger of the numerical value of the evaluation at a position corresponding to the second area 52 of the previous image of the camera 108.

  When the imaging unit 11 captures an image, the imaging unit 11 can display the image to be captured (imaging state) on the display 106 that is a display unit included in the mobile phone 10. At this time, in order to facilitate the above-described imaging, as shown in the imaging example of FIG. 4, a frame indicating the first area 51 and a frame indicating the second area 52 are overlapped on the display. It may be displayed.

  Note that the sizes and positions of the first region 51 and the second region 52 are not limited to those shown in FIGS. 3 and 4 and are arbitrarily set so as to achieve the above object.

  The evaluation target information extraction unit 12 is an evaluation target information extraction unit that extracts evaluation target information from the first region 51 in the image 50 input from the imaging unit 11. Specifically, the evaluation target information extraction unit 12 extracts a product name and a store name as evaluation target information from the first region 51 of the image 50 using an image recognition technique, a character recognition technique, or the like. Conventional techniques can be used as the image recognition technique and the character recognition technique used for extracting information. The evaluation target information extraction unit 12 stores the position of the first region 51 in the image 50 in advance. The evaluation target information extraction unit 12 outputs the extracted evaluation target information to the output unit 14.

  The evaluation information extraction unit 13 is an evaluation information extraction unit that extracts evaluation information from the second region 52 in the image 50 input from the imaging unit 11. Specifically, the evaluation information extraction unit 13 stores characteristic information indicating the characteristics of the user's finger shape and color. Based on the feature information, the evaluation information extraction unit 13 detects the number of user fingers reflected in the second region 52 using an image recognition technique or the like, and indicates the detected number of user fingers Is extracted as evaluation information. A conventional image recognition technique can be used for finger detection. The evaluation information extraction unit 13 stores the position of the second region 52 in the image 50 in advance.

  Here, the feature information indicating the shape or color feature of the user's finger may be, for example, information about each feature such as shape or color, or an image of the user placing his / her finger on the second area 52 ( An image with one finger out, an image with two fingers out, etc.) itself may be used. The feature information may be extracted based on an image of a user's finger captured in advance by the imaging unit 11 before the generation of the evaluation information. The evaluation information extraction unit 13 outputs the extracted evaluation information to the output unit 14.

  The output unit 14 is an output unit that outputs the evaluation information input from the evaluation information extraction unit 13 as evaluation information indicating the user's evaluation of the evaluation target indicated by the evaluation target information extracted by the evaluation target information extraction unit 12. is there. Specifically, the output unit 14 outputs the evaluation target information extracted from the same image 50 and the evaluation information in association with each other. As said output, the output part 14 is displayed on the display 106 of the mobile telephone 10 like the example of an analysis result of FIG. 4, for example. In this case, it is a display output. As shown in FIG. 4, “product name / store name” as evaluation target information and the number of stars indicated by the evaluation information are shown on the same screen.

  Moreover, as an output, the output part 14 is good also as transmitting the evaluation object information and evaluation information mutually matched to the merchandise information provision server 20, for example. This transmission is performed, for example, when the transmission button 71 displayed on the same screen is pressed by the user's operation on the mobile phone 10 while the display output is being performed.

  In addition, when the display output is being performed and the edit button 72 displayed on the same screen is pressed by the user's operation on the mobile phone 10, the evaluation target information or the evaluation information can be edited. Good (the evaluation target information and the evaluation information after editing may be transmitted in the same manner as described above). Further, when the save button 72 displayed on the same screen is pressed by the user's operation on the mobile phone 10 while the display is being output, the evaluation target information and the evaluation information associated with each other are displayed. You may memorize | store in the memory etc. with which the mobile telephone 10 is provided. Note that the output need not be performed all of the above, and for example, only one of display output and transmission may be performed. Other outputs may also be output. The above is the configuration of the mobile phone 10.

  Subsequently, processing (evaluation information generation method) executed by the mobile phone 10 according to the present embodiment will be described with reference to the flowchart of FIG. This process is performed, for example, when a user's operation on the mobile phone 10 (for example, a process for shifting to the evaluation information generation mode for performing the process according to the present invention) is performed as a trigger. It is also performed when the user wants to generate evaluation information about an evaluation target such as a product. Prior to this processing, the user's finger used for evaluation is imaged by the camera 108 in advance, and feature information indicating the characteristics of the user's finger is extracted based on the image and stored in the evaluation information extraction unit 13. deep.

  In this process, first, an image for generating evaluation information is captured and input by the imaging unit 11 (S01, image input step). As shown in the imaging example of FIG. 4, this imaging is performed so that the evaluation target information is shown in the first area 51 and the finger in a state corresponding to the evaluation information is shown in the second area 52. The user makes his / her finger in a state according to the evaluation for the evaluation target. The captured and input image is output from the imaging unit 11 to the evaluation target information extraction unit 12 and the evaluation information extraction unit 13.

  Subsequently, the evaluation target information extraction unit 12 extracts the evaluation target information from the first region 51 in the image 50 (S02, evaluation target information extraction step). The extracted evaluation target information is output from the evaluation target information extraction unit 12 to the output unit 14. Further, the evaluation information extraction unit 13 extracts evaluation information from the second region 52 in the image 50 (S03, evaluation information extraction step). The extracted evaluation information is output from the evaluation information extraction unit 13 to the output unit 14. Note that S02 and S03 are not necessarily performed in the above order, and may be performed in the reverse order or in parallel.

  Subsequently, the evaluation object information and the evaluation information extracted from the image 50 as described above are output by the output unit 14 (S04, output step). As this output, for example, it may be displayed and output as shown in the analysis result example of FIG. 4 or may be transmitted to the product information providing server 20. When the evaluation object information and the evaluation information are transmitted to the product information providing server 20, this information is used as evaluation information received and provided by the product information providing server 20. The above is the process executed by the mobile phone 10 according to the present embodiment.

  In the example of the embodiment described above, the information related to the evaluation is extracted from the image by the mobile phone 10, but the product information providing server 20 may extract the information, that is, generate the evaluation information. Good. That is, the product information providing server 20 may be an evaluation information generating device. In that case, the mobile phone 10 only captures an image, transmits the image to the product information providing server 20, and the product information providing server 20 performs the processing according to the above-described embodiment (the product information providing server 20). Has the function of the mobile phone 10 according to the present embodiment described above).

  However, in that case, the merchandise information providing server 20 inputs an image by receiving an image transmitted from the mobile phone 10 instead of inputting an image by imaging. Further, the form of output of the evaluation target information and the evaluation information may be different from that of the mobile phone 10. For example, the evaluation target information and the evaluation information generated in the storage device included in the product information providing server 20 may be output and stored as information provided by the product information providing server 20. Alternatively, the evaluation object information and the evaluation information generated are transmitted to the mobile phone 10 and displayed on the mobile phone 10 as in the analysis result example of FIG. 4, and transmitted, edited, and saved in the same manner as the above-described embodiment. It may be done.

  As described above, according to the present embodiment, the evaluation target information and the evaluation information are extracted based on the image. Accordingly, the first area 51 includes a (partial) image corresponding to evaluation target information such as a product package, and the second area 52 includes a (partial) image corresponding to evaluation information such as a user's finger. Evaluation information is generated simply by inputting an image. Therefore, according to the present embodiment, for example, evaluation information can be generated simply by picking up the number of fingers corresponding to the evaluation near the evaluation target package and performing imaging. That is, it is possible to easily generate evaluation information without performing an operation for a user to select an evaluation target as in the past and inputting information indicating evaluation such as a numerical value for the selected evaluation target. Can do.

  Moreover, it is desirable to extract evaluation information using the number of fingers of the user as in the present embodiment. When the user's finger is used in this way, the user can easily display the evaluation. Further, evaluation information is generated only by inputting an image showing the number of user fingers corresponding to the evaluation information in the second area 52. Therefore, evaluation information is generated easily and reliably. However, it is not always necessary to use the number of fingers of the user for extracting the evaluation information. In the present invention, information indicating evaluation may be acquired from the second region 52 of the image 50. For example, an image in which a numerical value of evaluation is written in the second area 52 may be used.

  Further, as in the present embodiment, it is desirable that an imaging unit such as the camera 108 is provided. According to this configuration, since an image for generating evaluation information can be acquired, the present invention can be reliably implemented. In addition, it is desirable to display a frame indicating the first region 51 and the second region 52 so as to overlap with an image to be captured at the time of imaging. According to this configuration, when an image for generating evaluation information is captured, it can be easily and reliably captured. In addition, the frame displayed at this time may be any of the frames indicating the first region 51 and the second region 52. However, the image pickup unit is not necessarily provided, and an image may be input from another device as in the case where the product information providing server 20 as described above is used as the evaluation information generation device.

  In this embodiment, the evaluation information generation device is the mobile phone 10 or the product information providing server 20, but is not necessarily limited to such a device, and may be any device as long as the above-described functions can be realized.
