Patent application EP17000734A (EP), filed 2017-04-27
Publication number: EP3244323A1
Title: IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, SEARCH APPARATUS, AND COMPUTER PROGRAM
Abstract: A captured image obtained by capturing a surface on which a color chart is disposed such that color information representing a color included in the color chart can be derived is acquired, the color information is derived from the captured image, and the color of the color chart that is contained in the captured image is extracted. Then, the derived color information and the extracted color are registered in association with each other.

Claims: number: 1
text: An image processing apparatus comprising:
number: 2
text: The image processing apparatus according to claim 1, further comprising
division means configured to divide a plurality of image capturing devices into a plurality of groups, based on histograms of colors extracted from captured images respectively captured by the plurality of image capturing devices, wherein
the acquisition means is configured to acquire captured images of the surface that have been captured under a plurality of image-capturing environments by one selected image capturing device selected from the group.
number: 3
text: The image processing apparatus according to claim 2, wherein
the derivation means and the extraction means perform the derivation and the extraction, respectively, on each of the captured images of the surface that have been captured under the plurality of image-capturing environments by the selected image capturing device.
number: 4
text: The image processing apparatus according to claim 3, wherein
the registration means is configured to register the color information derived by the derivation means for each of the captured images of the surface that have been captured under the plurality of image-capturing environments by the selected image capturing device and the color extracted by the extraction means in association with a corresponding one of the groups.
number: 5
text: The image processing apparatus according to any one of claims 1 to 4, wherein
the color included in the color chart is disposed on the surface in association with the color information representing the color.
number: 6
text: The image processing apparatus according to any one of claims 1 to 4, wherein
the color included in the color chart is disposed on the surface at a position corresponding to the color information representing the color.
number: 7
text: The image processing apparatus according to any one of claims 1 to 4, wherein
a character object that represents the color information representing the color included in the color chart and that has the color is disposed on the surface.
number: 8
text: The image processing apparatus according to any one of claims 1 to 7, further comprising:
number: 9
text: A search apparatus for searching for an image registered by the image processing apparatus according to claim 8, comprising:
number: 10
text: The image processing apparatus according to any one of claims 1 to 7, further comprising:
number: 11
text: A search apparatus for searching for an image registered by the image processing apparatus according to claim 10, comprising:
number: 12
text: The search apparatus according to claim 11, further comprising
means configured to update, to color information designated by a user, the color information registered by the registration means in association with the color registered by the second registration means in association with an image designated by the user from among images searched for by the search means.
number: 13
text: An image processing method comprising:
number: 14
text: A computer program for causing a computer to function as means of the image processing apparatus according to any one of claims 1 to 8 and 10.
