20100123876 | PROJECTOR, AND METHOD OF CONTROLLING PROJECTOR - A projector includes: a power supply device; an image projection device having a light source device; a sound processing device adapted to process a sound signal from an external microphone; and a control device adapted to control the power supply device, wherein the control device can selectively set either one of a first operation mode in which the light source device and the sound processing device are made to be supplied with electrical power and a second operation mode in which the sound processing device is made to be supplied with the electrical power while halting supplying the electrical power to the light source device, and the control device controls the electrical power supply by the power supply device to the light source device and the sound processing device based on the operation mode set. | 05-20-2010 |
20100316234 | PROJECTOR AND AUDIO OUTPUT METHOD - A projector includes: a first audio input section adapted to input a first sound signal; a second audio input section adapted to input a second sound signal; a first sound amplifier section adapted to amplify the first sound signal received through the second audio input section to generate a first amplified signal; a second sound amplifier section adapted to amplify the second sound signal received through the second audio input section to generate a second amplified signal; a first audio output section adapted to output a first sound based on the first amplified signal; a second audio output section adapted to output a second sound based on the second amplified signal; and a determination section adapted to determine whether or not the first sound signal is being input. | 12-16-2010 |
20110109542 | IMAGE DISPLAY DEVICE AND METHOD OF CONTROLLING THE SAME - An image display device includes: a first audio signal input terminal to which a first audio signal is input from a microphone; and a control section adapted to control power supply from a power supply circuit to the microphone based on type information indicative of whether a type of the microphone to be connected to the first audio signal input terminal is a first type which is requiring power supply or a second type which is not requiring power supply. | 05-12-2011 |
20120086914 | PROJECTION DISPLAY DEVICE AND METHOD FOR CONTROLLING THE SAME - An electricity storage section that stores power from an external power source and supplies the stored power as operating power is provided, and, when an interruption of the external power source to a projection display device is detected, control to reduce the power consumption of a device main body and control to drive an exhaust port shutter so that it is closed by the power supplied from the electricity storage section are performed. | 04-12-2012 |
20140092312 | IMAGE DISPLAY APPARATUS AND METHOD OF CONTROLLING IMAGE DISPLAY APPARATUS - An image display apparatus includes: an HDBaseT receiver circuit that receives signals based on N (N is an integer number satisfying N≧2) standards that can be transmitted as HDBaseT signals; a dedicated receiver circuit that is compliant with only a first standard of the N standards and receives signals of the first standard; a signal processing unit that processes the signals received by the HDBaseT receiver circuit or the dedicated receiver circuit; and a circuit switching unit that switches an output target circuit that outputs the signals of the first standard to the signal processing unit to one of the HDBaseT receiver circuit and the dedicated receiver circuit. | 04-03-2014 |
20140232991 | PROJECTION DISPLAY DEVICE AND METHOD FOR CONTROLLING THE SAME - In at least one embodiment, a projection display device comprises a device main body, a shutter that opens and closes an opening for ventilation, and an electricity storage section that stores power from an external power source. If an interruption detecting section detects a power supply from the external power source is stopped and a time in which the power supply is stopped is longer than a predetermined time, the interruption detecting section detects that the external power source is interrupted. If the interruption of the external power source is detected, a control section performs a control to reduce a power consumption of the device main body and a control to drive the shutter so that the shutter is closed by the power supplied from the electricity storage section. | 08-21-2014 |
20150124172 | IMAGE DISPLAY APPARATUS AND METHOD OF CONTROLLING IMAGE DISPLAY APPARATUS - An image display apparatus includes: an HDBaseT receiver circuit that receives signals based on N (N is an integer number satisfying N≧2) standards that can be transmitted as HDBaseT signals; a dedicated receiver circuit that is compliant with only a first standard of the N standards and receives signals of the first standard; a signal processing unit that processes the signals received by the HDBaseT receiver circuit or the dedicated receiver circuit; and a circuit switching unit that switches an output target circuit that outputs the signals of the first standard to the signal processing unit to one of the HDBaseT receiver circuit and the dedicated receiver circuit. | 05-07-2015 |
20150256788 | PROJECTOR AND CONTROL METHOD FOR PROJECTOR - A projector includes a light source, a light modulation device that modulates light emitted from the light source according to a video signal, a projection optical system that projects image light which is modulated by the light modulation device, a display unit that is provided in a main body of the projector, an acquisition unit that acquires information indicating a state regarding the video signal, and a control unit that displays the information indicating a state regarding the video signal, acquired by the acquisition unit, on the display unit. | 09-10-2015 |
