A projector including a projection section that projects image light, a power supply section that supplies the projection section with electric power, a first enclosure that accommodates the projection section, and a second enclosure that accommodates the power supply section, wherein the second enclosure is fixed to a ceiling joist receiver that serves as a support member that supports a ceiling plate that partitions a space into a living room space and a space behind a ceiling, and the first enclosure and the second enclosure are configured to be separate from each other.

Projector

A projector includes a projector main body disposed in an attic above a ceiling plate and configured to project image light on a screen located in a room interior below the ceiling plate, a cover member set on the ceiling plate and configured to cover the projector main body, and a projection window provided in the cover member and configured to transmit the image light projected from the projector main body to the room interior side. The projection window is disposed further on the attic side than the ceiling plate to tilt with respect to the ceiling plate.

Projector including a cover member that covers a projecting section of the projector and a projection window provided in the cover member

A projector includes a power source accommodation section and a projection section body. The power source accommodation section is supported by a duct and accommodates a power source circuit that converts electric power supplied from the duct. The projection section body accommodates a projection section that projects an image, and the projection section body is so supported by the power source accommodation section that a direction in which the image is projected is adjustable.

Projector with adjustable support

A projector includes a power receiving terminal, a light source that emits light based on electric power supplied to the power receiving terminal, a light diffuser that adjusts the degree of diffusion of the light from the light source, a specifying section that alternately specifies one of illumination projection and image projection every time electric power supply to the power receiving terminal is started, and a light diffusion controller that controls the light diffuser so that when the specifying section specifies the illumination projection, the light diffuser diffuses the light from the light source, whereas when the specifying section specifies the image projection, the light diffuser transmits the light without substantially diffusing the light.

Projector and method for controlling the same

A projector includes an electricity reception terminal to which electric power is supplied via an electricity feed terminal, a projection section that includes a light source, a spatial light modulator, an irradiation system, and a projection system and projects light, and a control section that switches a content to another whenever electric power supply to the electricity reception terminal is initiated and causes the projection section to project light carrying an image related to the content selected in the switching operation.

Projector and method for controlling projector with changing content

A projector includes a projection section adapted to project a projection image on a projection surface including a target part, a detection section adapted to detect a distance from a predetermined position to the target part, and a control section adapted to set an area to be projected on the projection surface other than the target part out of the projection image as a partial area based on the distance thus detected, and change a display state of the projection image so that the partial area set is masked.

Projector and projection image control method

A projector can be easily attached by mounting a connecting unit to a socket for illumination in an ordinary home. Since the projector includes a communication unit configured to receive an electronic mail, the projector updates an image signal and adjusts a diffusion degree of modulated light by a light-diffusion adjusting unit on the basis of contents of the mail received by the communication unit. Therefore, when a user desires to inform family members who will return home that the user suddenly has to go out, if the user transmits in advance, to the projector, a mail including a message for a family member who returns home, the family member who returns home turns on an illumination switch at the entrance, whereby the projector can start up, perform an illuminating function, and clearly project and display the message.

Projector and control method therefor

A display device that can be used with another display device, includes: a display unit; a command receiving unit which receives a control command or ID information from an external remote controller; and a command processing unit. The display unit displays the display device's own ID in response to reception of the control command by the command receiving unit. If the command receiving unit receives the ID information indicating the display device's own ID after the display unit starts displaying the display device's own ID, the command processing unit performs processing corresponding to the control command.

Display device and control method for display device

A projector includes a projection section adapted to project light, a human detection section adapted to detect a human existing in a predetermined region, and a mode switching section adapted to switch an operation mode to one of a content mode for projecting light of an image related to a content by the projection section, and an illumination mode for projecting light for illumination by the projection section in accordance with a detection result of the human detection section.

Projector and method of controlling projector

A projector includes a light source, a light modulator having an image formation area to form an image, a projection system that projects the image on a display surface, an enclosure that holds at least the light modulator and the projection system, an inclination detection section that detects the inclination of the enclosure with respect to an axis along the optical axis of the projection system, and an image display control section that forms a reference line on the image formation area, the reference line having a predetermined angle with respect to a horizontal line irrespective of the inclination of the enclosure, and the image display control section changes the inclination of the reference line with respect to the image formation area in accordance with the inclination of the enclosure in such a way that the reference line has the predetermined angle with respect to the horizontal line.

Projector having inclination detection section for detecting inclination of projector enclosure and method for controlling the same

A projector includes a light source; a spatial light modulation device which modulates light from the light source according to an image that is written; a light diffusion device which adjusts a degree of diffusion of the light incident on the spatial light modulation device or the light emitted from the spatial light modulation device; and a light diffusion controller which controls the light diffusion device so that the light diffusion device diffuses the light when the light source starts to light up.
