## Abstract

In a color determination device (101) that determines a correspondence relationship between a character string indicating a color and the color indicated by the character string, a character string receiver (102) receives input of a character string; an image retriever (103) retrieves for an image relating to the received character string and obtains a plurality of images as a result of the image retrieval; a degree acquirer (104) represents, with a predetermined accuracy, colors appearing in the plurality of respective images and acquires degrees at which the colors represented with the predetermined accuracy appear in the plurality of images; and a color determiner (105) determines a color indicated by the received character string from the colors represented with the predetermined accuracy on the basis of the acquired degrees.

## Claims

### Claim 1

A color determination device comprising
a character string receiver that receives input of a character string;
a degree acquirer that represents, with a predetermined accuracy, one or more colors appearing in each of a plurality of images obtained as a result of retrieving for an image relating to the received character string, and acquires a degree at which the on or more colors represented with the predetermined accuracy appear in each of the plurality of images; and
a color determiner that determines a color indicated by the received character string on a basis of the acquired degree, from the one or more colors represented with the predetermined accuracy.

### Claim 2 (depends on 1)

The color determination device according to claim 1, wherein
the degree is a value indicating a number of image in which the one or more colors represented with the predetermined accuracy appear, among the plurality of images, and
the color determiner extracts one or more colors having a highest degree from the one or more colors represented with the predetermined accuracy on a basis of the acquired degree, and determines a color indicated by the received character string on a basis of the extracted one or more colors.

### Claim 3 (depends on 2)

The color determination device according to claim 2, wherein
the color determiner determines that a color obtained by averaging the extracted one or more colors is a color indicated by the received character string.

### Claim 4 (depends on 1)

The color determination device according to claim 1, wherein
the degree is a frequency at which the one or more colors represented with the predetermined accuracy appear in each of the plurality of images, and
the color determiner extracts, on a basis of the acquired degree, one or more colors represented with the predetermined accuracy having a higher total number of the frequency in appearing in each of the plurality of images, and determines a color indicated by the received character string from the one or more extracted colors.

### Claim 5 (depends on 4)

The color determination device according to claim 4, wherein
the color determiner determines that a color obtained by averaging the one or more extracted colors using a total number of frequency of the one or more extracted colors as weights is a color indicated by the received character string.

### Claim 6 (depends on 1)

The color determination device according to claim 1, wherein
the degree acquirer removes, for each of the plurality images, a pixel having the same color as the pixel at a corner of the image from a peripheral boarder of the image, and then represents a color appearing in the image with the predetermined accuracy.

### Claim 7 (depends on 1)

The color determination device according to claim 1,
further comprising an image retriever to retrieve for an image relating to the received character string, and
wherein the degree acquirer acquires the degree from the plurality of images obtained as a result of image retrieval by the image retriever.

### Claim 8 (depends on 1)

The color determination device according to claim 1, wherein
the color determiner clusters the acquired degree thereby to determine that a representative color of each cluster is a color indicated by the received character string.

### Claim 9 (depends on 1)

The color determination device according to claim 1,
further comprising an image retriever that transmits an image retrieval request containing a query to specify the received character string to an external image retrieval device communicably connected to the color determination device, receives an image retrieval response in response to the image retrieval request from the image retrieval device, and obtains a plurality of images specified in the image retrieval response as a result of image retrieval, and
wherein the degree acquirer acquires the degree from the plurality of images obtained as the result of the image retrieval by the image retriever.

### Claim 10 (depends on 9)

The color determination device according to claim 9, wherein
the image retriever specifies, as the query, a character string meaning color in the language of the received character string, and the received character string.

### Claim 11 (depends on 1)

The color determination device according to claim 1, wherein
the received character string is a character string describing a color of a product,
the determined color is a representative color of the product, and
the color determiner determines that, among predetermined reference colors, a reference color that is most similar to the representative color of the product is a classification color of the product.

### Claim 12

A color determination system comprising: an image retrieval device that, on receiving an image retrieval request containing a query to specify a character string, retrieves for an image that conforms to the query, and transmits an image retrieval response that specifies a plurality of images obtained by the image retrieval; and a color determination device communicably connected to the image retrieval device, the color determination device comprising:
a character string receiver that receives input of a character string;
an image retriever that transmits an image retrieval request containing a query to specify the received character string to the image retrieval device, receives an image retrieval response in response to the image retrieval request from the image retrieval device, and obtains a plurality of images specified in the image retrieval response as the image retrieval;
a degree acquirer that represents one or more colors, with a predetermined accuracy, that appear in each of the plurality of images obtained as a result of the image retrieval, and acquires a degree at which the one or more colors represented with the predetermined accuracy appear in each of the plurality of images; and
a color determiner that determines a color indicated by the received character string on a basis of the acquired degree, from the one or more colors represented with the predetermined accuracy.

### Claim 13

A color determination method comprising:
a character string receiving step to receive input of a character string;
a degree acquisition step to represent with a predetermined accuracy, one or more colors that appear in each of a plurality of images obtained as a result of retrieving for an image relating to the received character string, and to acquire a degree at which the one or more colors represented with the predetermined accuracy appear in each of the plurality of images; and
a color determination step to determine a color indicated by the received character string on a basis of the acquired degree, from the one or more colors represented with the predetermined accuracy.
