Abstract
A projector includes: an image information input unit to which an SD card storing image information and a group ID is coupled; a screen displaying an image based on the image information; a communication unit coupled via a network to another projector having an SD card storing image information, the communication unit communicating with the another projector; and a control unit determining whether a group ID corresponding to the group ID is stored in the SD card or not, based on communication by the communication unit, the control unit synchronizing a display of the image by the screen and a display of an image based on the image information by the another projector when the group ID is stored in the SD card.
Claims15
A display device comprising:
- an interface to which a first storage device storing first image information and a first identifier is coupled;
- a display unit displaying a first image based on the first image information;
- a communication unit coupled via a network to another display device having a second storage device storing second image information, the communication unit communicating with the other display device;
- and
- a control unit determining whether a second identifier corresponding to the first identifier is stored in the second storage device or not, based on communication by the communication unit, the control unit synchronizing a display of the first image by the display unit and a display of a second image based on the second image information by the another display device when the second identifier is stored in the second storage device.
A display system comprising a first display device and a second display device coupled together via a network,
- the first display device having a first interface to which a first storage device storing first image information and a first identifier is coupled,
- the second display device having a second interface to which a second storage device storing second image information is coupled,
- the first display device comprising:
- a display unit displaying a first image based on the first image information;
- a communication unit communicating with the second display device via the network;
- and
- a control unit determining whether a second identifier corresponding to the first identifier is stored in the second storage device or not, based on communication by the communication unit, the control unit synchronizing a display of the first image by the display unit and a display of a second image based on the second image information by the second display device when the second identifier is stored in the second storage device.
A display method by a display device, the method comprising:
- causing the display device to couple to a first storage device, the first storage device storing first image information and a first identifier;
- causing the display device to communicate via a network with another display device having a second storage device storing second image information;
- determining whether a second identifier corresponding to the first identifier is stored in the second storage device or not;
- and
- synchronizing a display of the first image based on the first image information and a display of a second image based on the second image information by the other display device when the second identifier is stored in the second storage device.
