A signal detection device of the present invention includes a first control unit configured to determine whether there are inputs of a plurality of external signals connected thereto, a second control unit configured to be activated after the first control unit is activated, a first input unit connected directly to the first control unit and configured to input a first external signal, which is one type of the plurality of external signals, and a second input unit connected to the first control unit via the second control unit and configured to input a second external signal, which is another type of the plurality of external signals, and the first control unit determines whether there is an input of the first external signal before the second control unit is activated and determines whether there is an input of the second external signal after the second control unit is activated.

A display method includes acquiring captured image data generated by capturing an image of a second area containing a first area, the captured image data containing first partial data representing an image of the first area and second partial data representing an image of the second area, recognizing an object located in the first area by using the first partial data with no use of the second partial data, displaying a first image that underwent a first process according to the position of the object when the object is recognized as a first pointing element and when the object moves from the first area onto a display surface, and displaying a second image that underwent a second process according to the position of the object when the object is recognized as a second pointing element and when the object moves from the first area onto the display surface.

A vehicle projection system that includes a projector positioned adjacent a first portion of a ceiling of the vehicle, the projector being configured to project a first image on the first portion of the ceiling. The image may be a moving image or may be various natural sky scenes such as a starry sky. The projector may be a pico-projector or a micro-projector. The vehicle may be an aircraft with the projector positioned on an overhead portion of the cabin. The projector may be positioned between two overhead bins. A second projector positioned on an overhead portion of the cabin may be configured to project a second image on a second portion of the ceiling. The projectors may be positioned on curtain headers within the aircraft. The system may include a control panel that controls the operation of the projectors in conjunction with an onboard sound system, if any.

A projection capture system includes a camera to capture images of objects in a capture space, and a projector to illuminate the objects in the capture space and to project images captured by the camera into a display space. The projector includes a flash mode for providing white light for illuminating the objects in the capture space. The system includes a controller to adjust drive settings to LEDs of the projector to achieve a predetermined white point during the flash mode.

A projection apparatus and a direct setting method of a projection image are provided. The projection apparatus includes a projection device, an input interface, and a processing device. The input interface is configured to provide a plurality of setting items. The processing device is coupled to the projection device. When the projection device projects a projection image, the processing device is configured to directly set an image format of the projection image according to a setting signal provided by the input interface in response to selection of one of the setting items. The disclosure provides a fast image format setting function for the projection image.

An illumination device with projector includes a projector having a projection optical system, a projector holding section configured to hold the projector, a stand part to be coupled to the projector holding section, and a shade which is configured to cover a periphery of the projector holding section, and is provided with a projection opening through which projection light emitted from the projector is transmitted. The projector holding section is provided with an angle adjustment mechanism for changing a tilt angle of the projector centering on an end portion at an exit side of the projector.

The displaying apparatus unit according to the present invention includes a first holder configured to hold a displaying element, a second holder configured to hold an optical operating plate which operates on light from the displaying element, a first dustproof cover member disposed between the first holder and the second holder, and configured to cover a whole side surface of the displaying element, and a second dustproof cover member disposed between the first dustproof cover member and the second holder, wherein the first dustproof cover member is in contact with the first holder, the second dustproof cover member is in contact with the second holder, the first dustproof cover member and the second dustproof cover member are in contact with each other, and the first dustproof cover member has a hardness higher than that of the second dustproof cover member.

An image system including a sensor cluster module to detect and capture surface area values of an object and communicate surface area values to a computing device and a projector to receive boundary values related to the surface area values of the object and image content of an image from the computing device, the projector to project the image content within and onto the surface area of the object.

A holographic image display device according to one embodiment comprises: an image display unit on which a holographic image is displayed; and a spatial impression providing unit which forms a space surrounding the holographic image, and includes a transparent color material such that the space looks colored and the holographic image can be recognized from the outside.

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.
