PROBLEM TO BE SOLVED: To exhibit higher performance of object identification in a device having little processing resources.SOLUTION: There is provided a terminal device, comprising: an image acquisition part that acquires a photographed input image; a transmission part that transmits the input image and assistance information to a server including a first feature amount dictionary that is collated with the feature amount of the input image in order to identify an object captured in the input image; and a reception part that receives, from the server, a second feature amount dictionary that is acquired by the server according to the assistance information and a result of identification of the object based on the first feature amount dictionary and includes the feature amount on a co-occurring object that is likely to co-occur with the object identified on the basis of the first feature amount dictionary, where the accuracy of an algorithm to be used for extraction of the feature amount included in the first feature amount dictionary is different from the accuracy of an algorithm to be used for extraction of the feature amount included in the second feature amount dictionary.SELECTED DRAWING: Figure 4 |
