摘要： A light source device includes a laser source unit, a rotating body including a phosphor layer and a reflective diffusion plate, and an optical path forming member that divides the emitted light of the laser source unit into a first laser beam and a second laser beam, irradiates the reflective diffusion plate with the first laser beam, and irradiates the phosphor layer with the second laser beam. The optical path forming member includes a first reflection plate with a through-hole and a first collimator lens. The first laser beam passes through the through-hole and the first collimator lens in that order and enters the reflective diffusion plate, and the diffused light from the reflective diffusion plate passes through the first collimator lens and enters the first reflection plate.

摘要： A projection-type display device includes: an operation signal detector, configured to receive an operation signal that indicates adjustment content of a projected image that was instructed by way of an operation unit; an installation state detector, configured to detect, as an installation state of the projection-type display device, a first state and a second state that is rotated 90 degrees from the first state around an axis that is parallel to an optical axis of a projection lens; and a controller that, upon detecting a signal that corresponds to a first direction by way of the operation signal detector in the first state and the second state, adjusts the projected image by causing the projected image to shift in the first direction, or adjusts the projected image by causing a correction-object site in the projected image to move in the first direction.

摘要： A display device is in a multi-monitor system in which a plurality of display devices are connected using a daisy chain to display an image signal. The display device may include, but is not limited to, a reception unit configured to receive signal information that is information regarding a display of the image signal on a display device from the display device connected to an own display device; a comparison unit configured to compare the received signal information and signal information of the image signal in the own display device; and an output unit configured to output an instruction to perform a reset on at least one of the plurality of display devices when the two types of signal information are determined to be different as a result of the comparison.

摘要： A content attribute acquisition unit acquires a plurality of pieces of content attribute information respectively indicating attributes of a plurality of contents to be displayed before a main part of a movie. An order determination unit determines, using the plurality of pieces of content attribute information, a display order of the plurality of contents and outputs order information indicating the display order to a screening content generation device. A content storage unit stores the plurality of contents as well as the plurality of pieces of content attribute information. The content attribute acquisition unit acquires the plurality of pieces of content attribute information from the content storage unit, and also acquires the plurality of contents from the content storage unit. The order determination unit outputs to the screening content generation device, the order information together with the plurality of contents acquired from the content attribute acquisition unit.
