A second projector disposed so as to be opposed to a projection surface includes a projection section configured to project second image light on the projection surface on which a base image is displayed, and visibility of the base image on which the second image light is projected is made lower than in a state in which the second image light is not projected on the projection surface.

Projector that lowers visibility of base image, projection system and projection method

A projector is configured to project an image to one side with respect to an installation surface. The projector includes: a housing that is configured to be fixed to the installation surface, a projection section that is built in the housing and configured to project image light from one end of the housing, an adjustment mechanism that is configured to adjust a posture of the projection section with respect to the installation surface, a drive section that is configured to drive the adjustment mechanism, and an operation detecting section configured to detect an input operation corresponding to the adjustment mechanism.

Projector configured to be integrated with a surface

A change in position or direction of a projector may be detected by a simple configuration. A projector includes a light projection unit that projects an image, a projection unit main body that houses the light projection unit, and a power supply housing part that supports the projection unit main body. Further, the projector includes an imaging part provided in either of the power supply housing part or projection unit main body, and a control unit that detects a relative position or relative direction between the projection unit main body and the power supply housing part based on a captured image of the imaging part.

Projector and control method for projector that detects a change of position based on captured image

A projector that projects image light on a projection surface and including a light modulator that modulates light emitted from a light source to form the image light, an optical path deflecting section that changes the projection direction of the image light modulated with the light modulator, a projection system that projects the image light outputted from the optical path deflecting section on the projection surface, a vibration detecting section that detects vibration acting on the projector, and an optical path deflection controlling section that controls the amount of change in the projection direction deflected by the optical path deflecting section based on the vibration detected by the vibration detection section.

Projector

A projector is attached to an opening provided in an installation surface and projects an image to one side with respect to the installation surface. The projector includes: an exterior panel exposed on the one side; a projection section that projects image light from a projection port formed in the exterior panel to the one side; and a rotation adjustment mechanism and an inclination adjustment mechanism that adjust a posture of the projection section with respect to the installation surface.

A projection system including a first projector and a second projector project images side by side, wherein the first projector includes a first projection section that projects a first image and a first control section that causes the first projection section to project an identification image containing identification information, and the second projector includes a second projection section that projects a second image, an imaging section that captures an image of a range including the projection range of the second projection section to produce a captured image, and a second control section that causes the imaging section to capture an image of the identification image projected by the first projector, acquires the identification information on the first projector based on the captured identification image, and determines the position of the first image relative to the second image based on the position of the identification image in the captured image.

Projection apparatus, projector, and projector controlling method

A projector that projects image light on a projection surface includes a light modulator that modulates light emitted from a light source based on image information to form the image light, a projection system that projects the image light modulated by the light modulator on the projection surface, a light modulator moving section that changes the position of the light modulator, a vibration detecting section that detects vibration acting on the projector, and a controller that causes the light modulator moving section to change the position of the light modulator based on the vibration detected by the vibration detecting section.

Projector and method for controlling 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.

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

An lighting equipment having an illumination capability and an image projection capability includes a light source unit () that functions as a light source for illumination and a light source for image projection, an image formation unit () that modulates light from the light source unit based on image information for illumination or image information for image projection to form an image, a projection unit including a lens () that projects the image formed by the image formation unit on a projection surface, a control unit () that controls the light source and the image projection unit, and a connection unit () electrically connectable to an existing lighting equipment attachment member ().

Lighting equipment and image projector

An document camera used by being connected to a display apparatus is provided. The document camera includes a plurality of imagers, an image processing unit that produces two sets of image data by using two of the plurality of imagers to capture images of a single target object from different imaging positions, a parameter acquisition unit that acquires a parameter for determining an inter-image distance between the two sets of image data to be displayed by the display apparatus, and an output unit that outputs the two sets of image data and the parameter or the inter-image distance to the display apparatus.

Document camera, method for controlling document camera, program, and display processing system

A lighting device includes a lighting unit and an enclosure (e.g., a shade) configured to cover a part or all of the periphery of the lighting unit and transmit light from the lighting unit. The lighting unit includes a light source section for lighting configured to radiate light and a video forming section configured to form video light obtained by modulating, on the basis of video information, light from a light source section for video formation configured integrally with or separately from the light source section for lighting and project the video light on the enclosure.
