Embodiment Construction

[0055] Next, exemplary embodiments of the present invention will be described in conjunction with the invention. In the present description and drawings, the same components having the same functions are assigned the same reference numerals, thereby omitting repeated descriptions.

[0056] (first exemplary embodiment)

[0057] figure 1 is a diagram of a configuration of a multi-display system according to a first exemplary embodiment of the present invention.

[0058] figure 1 The multi-display system 100 shown in includes two projectors 10 and a PC (Personal Computer) 20 as a source of video signals. Of the two projectors 10 , the projector 10 that is directly connected to the PC 20 and is arranged on the left side when viewed toward an image projected by the projector is referred to as a main projector 10M. The projector 10 arranged on the right side when viewed toward an image projected by the projector 10 is referred to as a slave projector 10S.

Abstract

Provided is a display device that can display images in a resolution according to a system constitution even when a general-purpose signal source is used. A receiving unit (3) receives an image signal output by a higher level device. A display unit (5) displays at least part of the image according to the image signal. A storage unit (2) stores the resolution of the image displayed on the display unit. A connection unit (8) can connect with a lower level display device. A communications unit (7) receives a second resolution, which is a resolution in a notification from the lower level display device, and outputs an image signal to the lower level display device when the lower level display device is connected to the connection unit. A control unit (9) notifies the upper level device of a third resolution, which is a resolution for image displayed on the display unit that has been stored in advance in the storage unit, according to the first resolution, which is the display unit resolution, and the second resolution.

Description

technical field [0001] The present invention relates to a display device, a multi-display system and a multi-display method. Background technique [0002] Recently, the number of multi-display systems that display a single image by using a plurality of display devices has greatly increased. A multi-display system includes a signal source that supplies a video signal and a plurality of display devices that display images based on the video signal output from the signal source, and performs a multi-display in which images displayed by each individual display device are combined to form A single combined image. Therefore, in a multi-display system, it is possible to form a large-scale image with a higher resolution than that displayed by each individual display device. [0003] There is a multi-display system in which a plurality of display devices are connected to a signal source in layers (see Patent Document 1). In this case, a signal source outputs a single video signal,...
