Patent number: 9760332Abstract: A system displays an image using a plurality of projection type display devices, and is capable of reliably notifying a user who uses the system that an error has occurred in a certain projection type display device. A slave includes a display unit that projects and displays an image and a signal receiving unit that receives data transmitted from a commander. The slave includes a detection unit that detects an error in the commander on the basis of the receiving conditions of the data in the signal receiving unit. The slave includes a display control unit that, when an error is detected by the detection unit, makes the display unit display an image showing that the error has been detected.Type: GrantFiled: December 20, 2016Date of Patent: September 12, 2017Assignee: SEIKO EPSON CORPORATIONInventors: Tadanori Aruga, Yutaka Yasuda, Toru Katahira

Patent number: 9635329Abstract: A projection system performs projection on a projection surface using a plurality of projectors including a first projector and a second projector. The projection system projects, using the first projector, a first guide in a position a predetermined amount of a margin spaced apart from a border of a projection region where an image is projected and projects, using the second projector, a second guide distinguishable from the first guide.Type: GrantFiled: December 15, 2015Date of Patent: April 25, 2017Assignee: SEIKO EPSON CORPORATIONInventors: Tadanori Aruga, Yutaka Yasuda, Toru Katahira

Patent number: 9373150Abstract: In the case where a projector is used in combination with another projector, individual use of only one projector is enabled. A slave projector operates together with a master projector. In this case, the operation methods to start up the projector are a first method in which only a first key is pressed, a second method in which the first key and a second key are pressed simultaneously, and a third method in which the first key and a third key are pressed simultaneously. When the slave projector detects a user's operation with a remote controller, if the operation is done by the first method or the second method, the slave projector ignores this operation. Meanwhile, if the operation is done by the second method, the slave projector starts up the own device irrespective of the command from the master.Type: GrantFiled: March 29, 2013Date of Patent: June 21, 2016Assignee: SEIKO EPSON CORPORATIONInventors: Tadanori Aruga, Toru Katahira, Yutaka Yasuda

Patent number: 9258538Abstract: A projector modulates light emitted from a light source and projects the light, the projector including an image acquiring unit, a modulating unit, a light adjusting mechanism, and a light adjusting control unit. The image acquiring unit acquires an image from an image source. The modulating unit modulates the light emitted from the light sources, based on the image acquired by the image acquiring unit. The light adjustment mechanism reduces an amount of light incident on the modulating unit from the light source. The light adjustment control unit performs light adjustment control by the light adjustment mechanism, based on the image acquired by the image acquiring unit. The light adjustment control unit performs control to increase the amount of light incident of the modulating unit when the light adjustment mechanism maintains a predetermined light-adjusted state.Type: GrantFiled: April 21, 2015Date of Patent: February 9, 2016Assignee: Seiko Epson CorporationInventors: Tatsuhiko Nobori, Toru Katahira, Katsuhiro Matsuyama, Haruyoshi Yamada

Patent number: 9004694Abstract: A display system displays images projected by a plurality of projection type display devices so as to overlap each other. When a user uses this system, events occurring in these devices can be reliably delivered to the user. A commander and a slave project and display images so as to overlap each other. When a notification-required event occurs in the commander or the slave, the commander specifies this notification-required event. Then, the commander displays a first OSD image between the first OSD image and a second OSD image, which form an image corresponding to the specified notification-required event, in a predetermined region of a first screen of screens on which images are displayed. Also, the commander outputs to the slave a control signal to display the second OSD image in the predetermined region. The slave displays the second OSD image in the predetermined region when the control signal is received.Type: GrantFiled: January 22, 2013Date of Patent: April 14, 2015Assignee: Seiko Epson CorporationInventors: Tadanori Aruga, Yutaka Yasuda, Toru Katahira
