摘要： A projector has a light source, image forming units, a projection lens, a first optical system and a second optical system. The image forming units form image light by adjusting, on a per-pixel basis, the intensity of light emitted by the light source. The projection lens projects the image light formed by the image forming units to the outside. The first optical system guides light of a first wavelength emitted by the light source to the projection lens, and the second optical system guides light of a second wavelength emitted by the light source to the projection lens. The f-number of the first optical system is higher than the f-number of the second optical system.

摘要： A light source device includes a light source, a phosphor unit that includes a phosphor region and a reflection region and that is movable so that blue light from the light source is sequentially radiated to the phosphor region and the reflection region, and a dichroic mirror that guides the first linearly polarized light of the blue light from the light source to the phosphor unit and on which fluorescent light from the phosphor region and the blue light from the reflection region are made incident. A ¼ wavelength plate is provided on an optical path between the dichroic mirror and the phosphor unit, and a polarized light separating element is provided on an optical path between the dichroic mirror and the light source. The dichroic mirror is disposed so that the incident angle of the central beam of the blue light from the reflection region is larger than 45°.

摘要： A display device includes a processing unit that determines whether a plurality of videos can be displayed side by side without overlapping each other in a display unit without changing resolutions of the plurality of videos. When the processing unit determines that the plurality of videos can be displayed, it causes the display unit to display the plurality of videos side by side without overlapping each other without changing the resolutions of the plurality of videos. When the processing unit determines that the plurality of videos cannot be displayed, it changes a resolution of at least one of the plurality of videos based on a resolution of the display unit, the resolutions of the plurality of videos, and a priority order, and causes the display unit to display the plurality of videos including the video for which the resolution has been changed side by side without overlapping each other.
