20100110395 | IMAGE DISPLAY DEVICE AND LAMP UNIT - A lamp unit is provided with a storage part that holds lamp management information in a writable and readable manner. A communication control part on a projector main unit side reads the lamp management information from the lamp unit and stores the same in a storage part of the main unit. The lamp management information is updated depending on the status of use of the lamp unit. The updated lamp management information is written back into the storage part of the lamp unit. | 05-06-2010 |
20100117539 | LAMP OPERATION DEVICE AND IMAGE DISPLAY DEVICE - A lamp operation device includes a mode setting part that sets an operation mode for lamps, and a lamp operation part that controls switching between the lamps in accordance with the set operation mode. The lamp operation part includes a process corresponding to a manual switching mode in which a lamp selected by a user is set as an illumination lamp, and a process corresponding to an automatic switching mode in which the plurality of lamps is automatically set in sequence as an illumination lamp. In the automatic switching mode, after one lamp has been set as the illumination lamp, cumulative illuminating time (amount of change) of the lamp is measured. Then, the illumination lamp is switched to the other lamp, depending on whether a measurement result has exceeded predetermined threshold time. | 05-13-2010 |
20100315845 | POWER SOURCE CIRCUIT AND PROJECTION DISPLAY DEVICE - A power source circuit includes a DC voltage generating section which rectifies and smoothes an input AC voltage to generate a DC voltage; a switching regulator which converts the DC voltage into an AC voltage; a transformer which lowers the AC voltage; a first switch connected between a secondary winding of the transformer, and a load; and a control section which controls on/off of the switch. The control section controls the first switch to turn off the first switch at a time of a waiting mode. | 12-16-2010 |
20110075056 | Projection Display Apparatus - A projection display device includes a first communication processing section for performing communications over a network; an interface that is connected to a communication device having a second communication processing section with more advanced processing capability than that of the first communication processing section; and a selecting section that selects the first communication processing section or the second communication processing section disposed in the communication device, for use in communications with the network. | 03-31-2011 |
20110090469 | PROJECTION DISPLAY DEVICE AND ELECTRONIC DEVICE - A projection display device includes a light source; a light modulating section that modulates light from the light source; a main control section that drives and controls the light source and the light modulating section for operation; a standby control section that performs control in a standby state; a main power source unit that supplies power to the main control section; and a standby power source unit that, in the standby state, shuts off power supply from a commercial power source to the main power source unit and supplies power to the standby control section. In this arrangement, the standby power source unit is disposed on a substrate different from that the main power source unit is disposed on. | 04-21-2011 |
20110149254 | PROJECTION DISPLAY DEVICE, PORTABLE TERMINAL DEVICE, AND PORTABLE CAMERA - A projection display device modulates light from a light source and projects the modulated light onto a projection plane. The projection display device includes a brightness detecting section that detects the brightness of a surrounding environment and a brightness notifying section that makes a notification in accordance with a result of detection by the brightness detecting section. | 06-23-2011 |
20110255058 | ELECTRICAL DEVICE AND PROJECTION DISPLAY DEVICE - An electrical device includes a plurality of filters having filter performances different from each other; a filter switching section which switches a filter to be disposed in a channel of a fluid flowing into a main body of the device between the plurality of filters; a switching control section which controls the filter switching section; and a determining section which determines the type of unwanted matter contained in the fluid. In this arrangement, the switching control section controls the filter switching section to dispose the filter corresponding to the type determined by the determining section in the channel. | 10-20-2011 |
20110279790 | PROJECTION DISPLAY DEVICE - A projection display device includes: a projection portion which enlarges and projects the light modulated by a imager portion; a control circuit; and a main body cabinet. The projection portion is formed by a projection lens portion into which the light from the imager portion is entered and a mirror portion which reflects the light having passed through the projection lens portion and lets the light travel toward a projection plane. The mirror portion is disposed so as to be shifted from an optical axis of the projection lens portion in a direction opposite to a direction in which the incident light from the projection lens portion is turned back. The control circuit portion is disposed in a space which is produced between the projection lens portion and the main body cabinet by a position gap between the projection lens portion and the mirror portion. | 11-17-2011 |
20110299045 | ELECTRICAL APPARATUS AND PROJECTION DISPLAY DEVICE - An electrical apparatus includes an air intake device which draws air into an apparatus body; a controller which controls the air intake device; a filter which removes unwanted matter from the air drawn into the apparatus body; and a removing device which removes the unwanted matter adhered to the filter. In this arrangement, the controller controls the air intake device to lower an air intake rate of the filter when the removing device is operated. | 12-08-2011 |
20130155113 | IMAGE DISPLAY DEVICE AND MOBILE DEVICE - A projection display device includes an image generating part which generates an image to be displayed on a predetermined image display surface; a circuit part which operates the image generating part based on an image signal; an image acquiring part which acquires an image signal to be outputted from a mobile device; a tilt acquiring part which acquires, from the mobile device, a tilt signal indicating a tilt angle of a display surface of the mobile device with respect to a reference state; and screen state changing part which changes a state of a screen to be displayed on the image display surface in accordance with the tilt signal. The screen state changing part inclines, on the image display surface, an image based on the image signal acquired by the image acquiring part, based on the tilt signal in accordance with the inclination of the display surface. | 06-20-2013 |
