The palette creating unit 42 creates a color palette in which a predetermined number of buttons created by the button creating unit 40 are arranged.
The order in which the buttons are arranged is not limited at all, but the value of the representative color of the button, for example, a vector of representative colors from the origin with black as the origin in the HLS color space (an average vector of representative colors of a predetermined number of product images) ) In the order of the values of the buttons is desirable because it can give a continuous feeling to the button colors. Also, there is no limitation on how the buttons are arranged.

In the color palette creating unit 20, the cluster classification unit 38 classifies the images of a plurality of products of a predetermined category stored in the image storage unit 18 into a predetermined number of clusters each including a predetermined number of product images. A predetermined number of buttons representing the average color of the representative colors of the images of the predetermined number of products included in each cluster as the number of the images of the products included in each cluster classified by the creation unit 40 and the representative color Is created, and the palette creating unit 42 creates a color palette in which a predetermined number of created buttons are arranged.
When the product image stored in the image storage unit 18 is changed, the color palette creation unit 20 dynamically creates a color palette corresponding to the changed product image.

Next, FIG. 4 is a conceptual diagram showing the configuration of the color palette of this embodiment. As shown in the upper side of the figure, the color palette 34 of the present embodiment has a predetermined number of buttons 36 of different representative colors arranged in a horizontal row.
Each button 36 corresponds to each cluster into which images of a plurality of products in one category are classified, and as a representative color, a representative color of a predetermined number of product images included in each cluster It is represented by the average color. In addition, the number of images of products included in each classified cluster, in other words, the number of products corresponding to each representative color is displayed in the button 36 with numbers (5, 7, 31, 15,...). ing.
It is not essential to display the number of products in the button 36. For example, the number of products may be displayed in the vicinity of the top, bottom, left, or right of the button 36.

Each of the one or more buttons 36 of the color palette 34 displays a sub-color palette 44 corresponding to a predetermined number of product images included in the corresponding cluster when the button 36 is designated.
In this case, in the color palette creating unit 20, as in the case where the color palette is created, the predetermined number of product images included in the cluster corresponding to the button 36 each include a predetermined number of product images ( 1 or more) sub-clusters, and the number of product images included in each of the classified sub-clusters, and the average of the representative colors of a predetermined number of product images included in each sub-cluster as representative colors A predetermined number (one or more) of sub-buttons 46 representing colors are created, and a sub-color palette 44 in which the created predetermined number of sub-buttons 46 are arranged is created.

As shown in the lower side of the figure, the sub color palette 44 of the present embodiment has a predetermined number of sub-buttons 46 of different representative colors arranged in a horizontal row as in the case of the color palette 34.
Each of the sub buttons 46 corresponds to each of a predetermined number of sub-clusters each including a predetermined number of product images, in which images of a predetermined number of products included in the corresponding cluster are classified. The representative color is represented by an average color of representative colors of a predetermined number of product images included in each sub-cluster. In addition, the number of images of products included in each classified sub-cluster, that is, the number of products, is displayed in the sub button 46 by numerals (14, 17).

  In the example shown in FIG. 4, when the number of images of products included in each cluster is 20 or more, when a button 36 of the color palette 34 is designated, a sub color palette 44 corresponding to the button 36 is displayed. Is done. For example, when the button 36 corresponding to the number of products is specified, 31 images of products included in the corresponding cluster are two corresponding to two sub-clusters classified into 14 images and 17 images, respectively. A sub color palette 44 including a sub button 46 is displayed.

Further, one or more sub-color palettes 44 are displayed each time the sub button 46 is designated until the number of product images included in the sub-cluster is less than a predetermined threshold set in advance. Displaying the color palette 44 can be repeated one or more times. That is, the color palette 34 can be hierarchized into two or more hierarchies.
Alternatively, each of the one or more buttons 36 of the color palette 34 includes, when the button 36 is designated, images of a predetermined number of products less than a predetermined threshold in which images of a predetermined number of products included in the corresponding clusters are classified. A sub color palette 44 including a predetermined number of sub buttons corresponding to a predetermined number of sub clusters including the image may be displayed.

  Subsequently, the web page storage unit 22 stores data of web pages of EC sites including the color palette created by the color palette creation unit 20.

The image search unit 24 selects a button or a sub-button of a color palette designated by an instruction input via an instruction input unit 30 (to be described later) from a plurality of product images of a predetermined category stored in the image storage unit 18. The image of the product of the color corresponding to the representative color of the sub button of the color palette is searched.
The image search unit 24 may search for an image of a product having a color corresponding to the representative color of the button from a plurality of product images, but the color palette creating unit 20 may search for a predetermined number of images of the plurality of products. Are stored in association with images of a predetermined number of products included in each cluster and buttons included in the color palette, and based on this, images from a plurality of products are stored. It is desirable to search for images of products included in the cluster corresponding to the button. The same applies to the sub color palette.

  The first data transmission / reception unit 26 transmits / receives data to / from each client 14 via the network 16.

  On the other hand, each client 14 browses a web page of an EC site, or browses a list of products having a color corresponding to a desired representative color searched using a color palette displayed on the web page. Or to purchase a desired product.

  Each client 14 is, for example, a PC (personal computer) or the like, and includes a display unit 28, an instruction input unit 30, and a second data transmission / reception unit 32, as shown in FIG.

  The display unit 28 includes a web page corresponding to the web page data stored in the web page storage unit 22, a list of product images searched by the image search unit 24, a detailed screen of each product, and the like. The display screen is displayed.

  The instruction input unit 30 is configured to select a predetermined button or sub button from a predetermined number of buttons or sub buttons of the color palette or sub color palette of the web page displayed on the display unit 28, or an instruction for browsing the web page of the EC site.

  Next, the operation of the image search apparatus 10 will be described according to the image search method of the present invention with reference to the flowchart shown in FIG.

  In the image search device 10, when the user wants to browse a web page of a predetermined EC site stored in the web page storage unit 22, an instruction for the browsing request is input via the instruction input unit 30 (step). S1).

  When a web page browsing request instruction is input, the browsing request is sent from the second data transmitting / receiving unit 32 of the predetermined client (first client) 14 used by the user to the first data transmitting / receiving unit of the server 12. 26 (step S2).

  When a web page browsing request is received by the first data transmission / reception unit 26, the web page data stored in the web page storage unit 22 is converted into a browsing request according to the received web page browsing request. The data of the corresponding web page is read out and transmitted (returned) from the first data transmitting / receiving unit 26 to the second data transmitting / receiving unit 32 of the predetermined client 14 that has requested browsing (step S3).

  When the web page data corresponding to the browsing request is received by the second data transmission / reception unit 32 of the predetermined client 14, the web page including the color palette shown in FIG. 4 corresponding to the received web page data is predetermined. Are displayed on the display unit 28 of the client 14 (step S4).

  Subsequently, an instruction for designating a button of a desired representative color from a predetermined number of buttons included in the color palette of the web page displayed on the display unit 28 of the predetermined client 14 is given by the user. It is input via the instruction input unit 30 (step S5).

  When an instruction for designating a button is input, if the number of product images included in the cluster corresponding to the designated button is equal to or greater than a predetermined threshold, the sub image corresponding to the designated button is displayed. The color palette is displayed. In this case, as in the case of the color palette, an instruction for designating a desired representative color sub-button from a predetermined number of sub-buttons included in the sub-color palette is given by the user. Is input through.

  When an instruction to specify a button or subbutton is input, the specified button or subbutton data is sent to a predetermined client as a search request for a product image of a color corresponding to the representative color of the specified button or subbutton. 14 from the second data transmitting / receiving unit 32 to the first data transmitting / receiving unit 26 (step S6).

  When the data of the designated button or sub button is received by the first data transmission / reception unit 26 as a product image search request, the image data is stored among the images of a plurality of products in a predetermined category stored in the image storage unit 18. The product image of the color corresponding to the received button or sub button data is retrieved, and the retrieved product image is transmitted from the first data transmitting / receiving unit 26 to the second data transmitting / receiving unit 32 of the predetermined client 14. (Reply) is made (step S7).

  When the image of the searched product is received by the second data transmitting / receiving unit 32 of the predetermined client 14 that has requested the search, a list of the images of the received product is displayed on the predetermined client 14 as shown in FIG. It is displayed on the part 28 (step S8).

  The user designates a desired product image from the list of product images displayed on the display unit 28, thereby causing the display unit 28 to display a product detail screen corresponding to the designated product image. , You can buy the product in the shopping cart.

In the image search device 10, the buttons of the color palette are displayed in the average color of the representative colors of the images of a predetermined number of products included in the corresponding cluster. Therefore, the user can easily grasp the distribution of the products of the color corresponding to the representative color, and can search for the product of the color that suits his image well.
In addition, since the buttons are displayed with the average color of the representative colors of the images of the predetermined number of products included in the corresponding cluster, the buttons corresponding to the images of the products with 0 products are not displayed. Therefore, the number of products corresponding to each button included in the color palette is not zero, and the narrowing down of product images by specifying the color is not wasted.
Further, since the number of images of products included in the cluster corresponding to the button is displayed, the user can check the number of products having a color corresponding to the representative color of each button.
When a button is designated, a sub color palette corresponding to the designated button can be displayed. Therefore, the number of images of the product corresponding to the button can be reduced, and the user can easily find a desired product from the images.

The color palette 34 is not limited to a predetermined number of buttons 36 arranged in a horizontal row. For example, a predetermined number of buttons 36 may be arranged in a vertical row or in a vertical and horizontal manner. It may be arranged in other ways.
Further, the method of displaying the button 36 and the number of products is not limited to the method of displaying the number of images included in each classified cluster by numbers.

For example, the color palette creation unit 20 represents, on a two-dimensional plane, each of a predetermined number of buttons having a size corresponding to the number of product images included in each classified cluster, that is, the number of products. An average color of representative colors of a predetermined number of product images included in the cluster corresponding to each created button in the color space, that is, a color palette arranged (displayed) at coordinates corresponding to the representative color of the created button You may create it.
The color space represented by the two-dimensional plane is represented by, for example, a two-dimensional plane composed of brightness and chromaticity in the HLS color space. In this case, the saturation setting can be freely changed, and the saturation can be freely changed.

The color palette shown in FIG. 8 is one in which buttons having a size corresponding to the number of products are arranged in a color space represented by a two-dimensional plane. In this color palette, each button is represented by a circle having a size corresponding to the number of product images included in the corresponding cluster, that is, the number of products. Each button is arranged at coordinates corresponding to the representative color of the button in a color space represented by a two-dimensional plane.

The color palette shown in FIG. 11 is one in which buttons having a width corresponding to the number of products are arranged side by side. In this color palette, each button is represented by the number of images of products included in the corresponding cluster, that is, the width corresponding to the number of products. Each button is displayed in a horizontal row.
The user can grasp the number of products of a color corresponding to the representative color of the button by looking at the width of each button.

  It should be noted that it is not essential to display the number of product images included in each classified cluster or sub-cluster on the button or sub-button.

It is not essential to display the representative color of each button in the average color of the representative colors of the predetermined number of products included in the corresponding cluster, and the representative image of each product included in the corresponding cluster. The colors may be displayed side by side. As a representative color of each product image, for example, an average color of all the representative colors included in each product image, or one selected from one or more representative colors included in each product image Display two representative colors. In this case, the buttons are displayed in multiple colors instead of a single color.
Thereby, the user can easily grasp the distribution of the products of the color corresponding to the representative color, and can search for the product of the color that suits his image well.

  When the button is displayed in multiple colors, as shown in FIG. 12A, the representative color of the image of each product included in the cluster extends in the vertical direction of the button, and each product included in the cluster. The representative colors of the images can be arranged in the horizontal direction of the button. Alternatively, as shown in FIG. 5B, the vertical and horizontal directions are interchanged so that the representative colors of the images of the products included in the cluster extend in the horizontal direction of the button, and the images of the products included in the cluster The representative colors can be arranged in the vertical direction of the button.

Furthermore, the representative colors of the buttons of the color palette are not limited to the above two examples, and can be represented by colors generated using the representative colors of the images of all the products included in the corresponding clusters.
In this way, by representing the representative colors of the buttons of the color palette with the colors generated using the representative colors of the images of all the products, the user can also distribute the products having the colors corresponding to the representative colors. You can easily search for products with colors that match your image.

  The order in which the representative colors of images of a predetermined number of products included in the cluster are arranged is not limited in any way, but one or more representative colors included in each product image or one or more included in each product image Values of mixed colors of, for example, in the HLS color space, with black as the origin, the representative color vectors from the origin (the average vector of the representative colors of the images of each product) are arranged in order, or Arranging the representative colors of the images of a predetermined number of products included in the cluster in the order of brightness, the order of hue, or the order of saturation, for example, can provide a continuous feeling of button colors.
