Abstract:
A projector includes: an external case provided with an opening through which light passes; a projection system disposed within an inside space of the external case, wherein the projection system includes a reflection member having a reflection surface capable of reflecting light received from a light source device to guide the light toward the opening, and projects the light to the outside of the external case via the opening; and a detection unit which detects a foreign material existing on the optical path of the light in the area of light exit of the opening.
Abstract:
A dimmer includes a pair of pivoting sections provided across an optical axis of a light beam and having pivot axes and a pair of light blocking sections held by the pair of pivoting sections and configured to pivot following pivoting of the pivoting sections to block the light beam. In a maximum light blocking state, positions in the optical axis direction of opposed ends on the optical axis side of the pair of light blocking sections are different from each other. In the maximum light blocking state, the opposed ends on the optical axis side of the pair of light blocking sections are arranged to overlap each other in a direction along the optical axis.
Abstract:
A projector includes an adjusting leg section configured to be capable of protruding/retracting outside/inside an exterior chassis and changing a tilt condition of the projector, an interlocking device that displaces based on the protruding/retracting movement of the adjusting leg section, a variable resistance device that has a resistance that varies based on displacement of the interlocking device, a voltage detection device that detects a voltage based on the resistance of the variable resistance device, a storage device that stores keystone distortion correction amount information, and a keystone distortion correction device that obtains a keystone distortion correction amount from the keystone distortion correction amount information based on the voltage detected by the voltage detection device, and that corrects the keystone distortion of the projection image using the keystone distortion correction amount.
Abstract:
A projector includes: an exterior housing configuring an exterior; a projection optical device which projects an image toward a projection surface; and a plurality of operation buttons which, being disposed in such a way as to be exposed to the outside of the exterior housing, an image opening for allowing the image projected from the projection optical device to pass through is formed in one sidewall, among sidewalls configuring the exterior housing, which intersects in a vertical direction, the projection optical device includes a reflecting mirror which reflects the image, and projects it through the image opening, and the plurality of operation buttons are disposed on a side of the one sidewall farther from the projection surface than the image opening.
Abstract:
An image pickup device includes an image pickup element which captures an image of a projection surface, an optical filter which has higher transmissivity for infrared light than for visible light, a visible light transmitting member whose transmissivity for visible light is higher than the corresponding transmissivity of the optical filter, and a switching unit which switches between a first condition where the optical filter is disposed on an optical path of light entering the image pickup element, and a second condition where the visible light transmitting member is disposed on the optical path.
Abstract:
A projector suspension device including a projection optical device having a reflecting mirror, and a suspension position adjustment mechanism, the suspension position adjustment mechanism includes: a pressing member which presses a first member and a second member; a screw member which, being fixed in the first member, passes through the second member; and a turning member which, by turning and engaging with the screw member passing through the second member, against the pressing force of the pressing member, adjusts the angle formed by the first member and second member, with a turning pivot set perpendicular to the axial direction of the screw member as the center.
