Information display device, information display system, and computer program product

摘要

An information display device of an embodiment includes: a storage unit that stores the image data in association with information of the image data; a retrieval condition receiving unit that receives an input of a retrieval condition; a retrieval unit that retrieves the image data from the storage unit according to the received retrieval condition; a display control unit that displays an entire image representing an entire range in which the retrieved image data is distributed on a client terminal; and an operation receiving unit that receives an operation of an input unit by a user on a screen on which the entire image is displayed. The display control unit extracts the image data included in a range represented by a locus formed by an operation of the input unit, and displays the extracted image data on the client terminal together with the entire image.

主权项

1. An information display device that manages and displays image data on a client terminal connected through a network, comprising:
a storage unit that stores the image data therein in association with information of the image data including multiple items; a retrieval condition receiving unit that receives an input of a retrieval condition; a retrieval unit that retrieves the image data from the storage unit according to the received retrieval condition; a display control unit that displays an entire image representing an entire range in which the retrieved image data is distributed according to the information of the image data on the client terminal; an operation receiving unit that receives an operation of an input unit by a user on a screen on which the entire image is displayed; and a generating unit that specifies multiple items for displaying the retrieved image data in a distributed form from the multiple items included in the information of the image data stored in the storage unit, judges, based on information of the retrieved image data, whether or not it is possible to distribute the retrieved image data on an axis based on each of the specified multiple items, and generates axes on which distribution is judged as possible, wherein the display control unit
extracts the image data included in a range represented by a locus formed by an operation of the input unit from among a retrieval result by the retrieval unit, anddisplays the extracted image data on the client terminal together with the entire image, and, at that time, displays the retrieved image data at display areas on the screen based on the generated axes.
