20080316144 | Image displaying system, image displaying device, image data outputting device, image displaying method, image displaying program, and image data outputting program - A system consisting of a plurality of terminals storing image data and an image displaying device which are connected with each other through a network capable of two-way communication has the disadvantage of decreasing in throughput on account of slow image data transfer over the network. The image displaying device performs two-way communications with each of the terminals by a communication means at the display device side. Also, the image displaying device acquires image data from a relevant terminal while instructing other terminals to suspend transmission by the image data acquisition controlling means, thereby suspending transmission of image data. The image displaying device displays images by the image displaying means based on the thus acquired image data. | 12-25-2008 |
20100046088 | PROJECTOR AND CONTROL METHOD OF PROJECTOR - A projector includes: a projection lens which includes a zoom mechanism capable of controlling a projection view angle; a zoom drive unit which drives the zoom mechanism; a zoom amount storing unit which stores a zoom amount provided by the zoom drive unit; an operation signal receiving unit which receives a predetermined operation signal; and a zoom control unit which controls the zoom drive unit in such a manner as to set an initial zoom condition determined based on the zoom amount stored in the zoom amount storing unit when the operation signal receiving unit receives the predetermined operation signal. | 02-25-2010 |
20100100847 | IMAGE DATA TRANSMISSION SYSTEM, PROCESS AND PROGRAM, IMAGE DATA OUTPUT DEVICE AND IMAGE DISPLAY DEVICE - There has been a problem of necessitating a complicated work for establishing a connection capable of intercommunication between a computer as server and a projector as client. | 04-22-2010 |
20130250251 | PROJECTOR AND PROJECTOR SYSTEM - A second projector is configured to be able to connect with a first projector via a USB cable including a VBUS line. The second projector includes an image projecting unit that modulates light emitted from a light source and projects the light, a USB communication unit that detects, in a standby state, the supply of power via a VBUS from the first projector, and a control unit that performs control to switch an operating state of the second projector between the standby state and a normal operating state. When the supply of power of the VBUS is detected by the USB communication unit, the control unit activates the second projector from the standby state to the normal operating state. | 09-26-2013 |
20130342576 | PROJECTOR, IMAGE DISPLAY SYSTEM, AND METHOD OF CONTROLLING PROJECTOR - An image display system includes a first projector and a second projector, and makes the first projector and the second projector operate in cooperation with each other to form a single projection image on a common screen. The first projector and the second projector are connected to each other via a signal line. A master control section of the first projector transmits a control signal to a subordinate control section of the second projector. The subordinate control section of the second projector controls a projection section of the second projector based on the control signal. Thus, the controllability of the image display system provided with a plurality of projectors is enhanced. | 12-26-2013 |

20140317725 | IMAGE DATA TRANSMISSION SYSTEM, PROCESS AND PROGRAM, IMAGE DATA OUTPUT DEVICE AND IMAGE DISPLAY DEVICE - When a connection is established between a server and projectors through, a communication command is issued according to UDP-based broadcasting to retrieve connectable projectors through. Thereafter, the projector to be connected is selected and is assigned an IP address to establish the connection. In this manner, a user can easily obtain a connection environment capable of intercommunication between the server and the projector. A TCP/IP communication command is used to input or output image data, ensuring reliable transmission. Since the authentication can be provided using a keyword projected during the connection establishment, it is possible to prevent an unauthorized access to the projector by an outsider. | 10-23-2014 |
20150204979 | POSITION DETECTION APPARATUS, PROJECTOR, POSITION DETECTION SYSTEM, AND CONTROL METHOD OF POSITION DETECTION APPARATUS - A position detection apparatus includes: an imaging portion that captures an image of a detection area for detecting indication positions of indicators; and an indicator detecting portion that detects the indication positions of the indicators based on operation image data captured by the imaging portion when indication operations by the indicators are performed in the detection area and background image data captured by the imaging portion when the indication operations by the indicators are not performed. | 07-23-2015 |
20150205345 | POSITION DETECTION SYSTEM AND CONTROL METHOD OF POSITION DETECTION SYSTEM - A projection system includes a light emitting apparatus that emits detection light to a detection area for detecting indication positions of indicators, and a projector that detects the indication positions of the indicators in the detection area. The projector includes an imaging portion that captures an image of the detection area, and a position detection portion that detects at least one of an image of light generated by the indicator and an image of the detection light reflected on the indicator from data of a captured image of the imaging portion, and discriminates and detects the indication positions of the indicator and the indicator based on light emission timings of the indicator and the light emitting apparatus. | 07-23-2015 |
20150205376 | POSITION DETECTING DEVICE, POSITION DETECTING SYSTEM, AND CONTROLLING METHOD OF POSITION DETECTING DEVICE - A projector includes a position detection unit and a calibration control unit. The calibration control unit executes first calibration relevant to a manipulation position of an indicator performing a manipulation on a screen, and second calibration relevant to a manipulation position of an indicator performing a manipulation on the screen. Then, the calibration control unit provides a user interface allowing indication of whether or not the second calibration is to be executed after the first calibration is executed. | 07-23-2015 |
20150208050 | PROJECTOR, DISPLAY APPARATUS, AND CONTROL METHOD OF PROJECTOR - A position detection portion of a projector detects an operation on a screen based on a captured image obtained by capturing the screen. A control portion executes a calibration in which positions in a projection image and positions in the captured image are associated with each other based on the captured image obtained by capturing the projection image projected by a calibration control portion based on auto calibration images in which marks for specifying positions are arranged. In addition, the calibration control portion executes the calibration based on the captured image corresponding to the plurality of auto calibration images which are different in arrangement states of the marks. | 07-23-2015 |
