Abstract

A display system displays, on each of a plurality of display devices arranged side by side, among image data of a plurality of pages, each of image data of the number of display devices, and reflects input information, which indicates information input by a user, on image data displayed on a master display device among the plurality of display devices. Moreover, the display system displays, on each of the plurality of display devices, among the image data of the plurality of pages, each of image data which is obtained by shifting the image data of the number of display devices in accordance with an operation on a page operation unit. Thereby, a viewer is able to view image data of several pages at once, and it is possible to reflect information input by a user even when image data of a target page is shifted backward or forward.

First claim

The invention claimed is:

1. A display system, comprising:
a plurality of display devices that are arranged side by side;
an input detection device that detects an input performed by a user to a master display device which is a display device designated from the plurality of display devices; and
a control device that is connected to the plurality of display devices and the input detection device, wherein
the control device includes
an image data display control unit that displays, on each of the plurality of display devices, among image data of a plurality of pages, each of image data of a number corresponding to a number of the plurality of display devices,
an input reflection display control unit that reflects input information, which indicates information input by the user, on image data of the image data of the number of display devices, which is displayed on the master display device, and
a page operation unit by which page feeding or page returning is performed to the image data of the number of display devices, which is displayed on the plurality of display devices, and
in a case where the page operation unit is operated, the image data display control unit displays, on each of the plurality of display devices, among the image data of the plurality of pages, each of image data which is obtained by shifting the image data of the number of display devices in accordance with an operation on the page operation unit.

2. The display system according to claim 1 , wherein
in a case where the image data of the number of display devices is subjected to page feeding, the input information is reflected on, of the image data of the plurality of pages, image data of a page previous to the image data displayed on the master display device, and
the image data of the page is displayed on each of at least two of the display devices by the page feeding.

3. The display device according to claim 1 , wherein
each of the plurality of display devices includes image data display region that serves as a display region on which image data is displayed,
the master display device of the plurality of display devices further includes a page operation display region that serves as a display region on which the page operation unit is displayed, and
the input detection device
detects, as the input information, an input performed by the user to the image data display region of the master display device, and
detects, as an operation on the page operation unit, an input performed by the user to the page operation display region of the master display device.

4. The display system according to claim 1 , wherein
in a case where there are N display devices as the plurality of display devices, one or a plurality of display devices, a number of which is less than N, are designated as master display devices.

5. The display system according to claim 1 , wherein
the plurality of display devices are arranged so as to be arrayed in a horizontal direction,
the image data display control unit
displays, on each of the plurality of display devices, among the image data of the plurality of pages, each of the image data of the number corresponding to the number of the plurality of display devices so as to be arrayed from a left side to a right side in order, in a case where letters represented by the image data of the plurality of pages are horizontally written, and
displays, on each of the plurality of display devices, among the image data of the plurality of pages, each of the image data of the number corresponding to the number of the plurality of display devices so as to be arrayed from the right side to the left side in order, in a case where letters represented by the image data of the plurality of pages are vertically written.

6. The display system according to claim 1 , wherein
the plurality of display devices are arranged in a ring shape so that each display surface thereof serves as an inner peripheral surface, and
each of the image data is displayed on each of the display devices.

7. The display system according to claim 1 , wherein
the plurality of display devices and control devices are constituted by a plurality of groups,
the control device of a master group that is a group among the plurality of groups, which is designated,
displays, on each of a plurality of display devices in the master group, among the image data of the plurality of pages, each of image data of a number corresponding to a number of the plurality of display devices in the master group, and
transmits the image data of the number of display devices to the control device of a slave group among the plurality of groups, which is a group other than the master group, and
the control device of the slave group displays, on each of a plurality of display devices in the slave group, among the image data of the number of display devices from the control device of the master group, each of image data of a number corresponding to a number of the plurality of display devices in the slave group.

8. The display system according to claim 7 , wherein
each of the plurality of groups is provided in a different region, and
the control device of the master group is connected to the control device of the slave group via a network.

9. A display method, comprising the steps of:
detecting an input performed by a user to a master display device that is a display device designated from a plurality of display devices which are arranged side by side;
displaying, on each of the plurality of display devices, among image data of a plurality of pages, each of image data of a number corresponding to a number of the plurality of display devices;
reflecting input information, which indicates information input by the user, on image data of the image data of the number of display devices, which is displayed on the master display device; and
displaying, in a case where a page operation unit by which page feeding or page returning is performed to each of the image data of the number of display devices, which is displayed on each of the plurality of display devices, is operated, on each of the plurality of display devices, among the image data of the plurality of pages, each of image data which is obtained by shifting the image data of the number of display devices in accordance with an operation on the page operation unit.
