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

An information display system, comprising:

• a client terminal;
• and
• an information display device that manages and displays image data on the client terminal,
• wherein the information display device includes
• 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 transmits an entire image, representing an entire range in which the retrieved image data is distributed according to the information of the image data to be displayed on the client terminal, to the client terminal,
• an operation receiving unit that receives an operation of an input unit of the client terminal 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 that is formed by an operation of the input unit from among a retrieval result by the retrieval unit,
• transmits the extracted image data to the client terminal, and
• makes the extracted image data display on the client terminal together with the entire image, and, at that time, makes the retrieved image data display at display areas on the screen based on the generated axes, and
• wherein the client terminal includes
• a communication unit that
• transmits the retrieval condition to the information display device, and
• receives the entire image and the extracted image data from the information display device, and
• a display unit that displays the extracted image data together with the entire image.

A computer program product comprising a non-transitory computer-usable medium having computer-readable program codes embodied in the medium for displaying image data on a client terminal, the program codes when executed causing a computer to execute:

• storing an image data in a storage unit in association with information of the image data including multiple items;
• first receiving that includes receiving an input of a retrieval condition;
• retrieving the image data from the storage unit according to the received retrieval condition;
• displaying 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;
• second receiving that includes receiving an operation of an input unit by a user on a screen on which the entire image is displayed;
• and
• specifying 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, judging, 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 generating axes on which distribution is judged as possible,
• wherein
• the displaying of the entire image includes
• extracting 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 retrieving, and
• displaying the extracted image data on a client terminal together with the entire image, and, at that time, displaying the retrieved image data at display areas on the screen based on the generated axes.
