In a projector system including a plurality of projector apparatuses each projecting a picture onto a curved screen of transmissive type having a convex rear side as viewed from a user, a control unit divides an input picture into a plurality of pictures, providing an overlapping region between pictures, and supplies a plurality of divided pictures to the plurality of projector apparatuses, respectively. Optical axis of light projected by the plurality of projector apparatuses intersect at a position farther than a central point of the curved screen, as viewed from the plurality of projector apparatuses.

A display method includes a first terminal connecting to a second terminal and obtaining a first gesture made by a user on a target shortcut in a first display interface, where the first display interface is an interface presented on the first terminal, and where target content corresponding to the target shortcut is not running in a foreground of the first terminal. Then, the first terminal sends first display data to the second terminal based on the first gesture, so that the second terminal displays the first display data in a second display interface, where the first display data is data correlated with the target content, and where the second display interface is an interface presented on the second terminal.

A light source apparatus according to an embodiment of the present disclosure includes: a supporting substrate including a phosphor layer on one surface; a driver that causes the supporting substrate to be rotationally driven; a first supporting member that is opposed to another surface opposite to the one surface of the supporting substrate; a plurality of first heat dissipation members each having heat dissipation performance different from each other depending on a distance from the phosphor layer, the plurality of first heat dissipation members being provided concentrically on the other surface of the supporting substrate; and a plurality of second heat dissipation members provided concentrically on a surface, of the first supporting member, that is opposed to the supporting substrate, the plurality of second heat dissipation members being disposed alternately with the plurality of first heat dissipation members.

A projector according to the present disclosure includes: an illumination optical system; a separator; a first light valve; a second light valve; and a projection optical system. The illumination optical system generates illumination light. The separator separates the illumination light from the illumination optical system into first illumination light and second illumination light. The first light valve is illuminated with the first illumination light separated by the separator and generates first image light. The second light valve is illuminated with the second illumination light separated by the separator and generates second image light. The first image light generated by the first light valve and the second image light generated by the second light valve enter the projection optical system through the separator. The projection optical system projects the first image light that has entered the projection optical system toward a first display region and projects the second image light that has entered the projection optical system toward a second display region.

A lighting device includes: a first light source unit including a plurality of laser elements and emitting a first light flux in a first direction; a second light source unit including a plurality of laser elements and being arranged to emit a second light flux in the first direction and to be spaced apart from the first light source unit by a first distance in a second direction orthogonal to the first direction; and an optical path shift optical system including: a first reflecting surface that reflects the second light flux emitted from the second light source unit toward the first light flux; and a second reflecting surface that is parallel to the first reflecting surface and reflects the second light flux reflected by the first reflecting surface to be parallel to the first light flux at a second distance shorter than the first distance.

An App image includes a display target area displayed on a cylindrical screen, a left margin area, and a right margin area. When a particle comes into contact with a boundary of the display target area and the right margin area, a display apparatus arranges, in the left margin area, a particle in the same mode as the mode of the particle such that the particle comes into contact with a boundary of the display target area and the left margin area. The display apparatus generates a plurality of images such that as the particle moves out to the right margin area from the display target area, the particle enters the display target area from the left margin area.

There is provided an image display method of a display device, the image display method including displaying a first image based on a first image signal received by wired communication, and starting displaying a second image based on a second image signal received by wireless communication, when detecting that the first image signal by the wired communication is not received.

An image projection apparatus includes a first light source to emit a first excitation light of a specific wavelength, a second light source to emit a second excitation light of a specific wavelength, a first planar wavelength conversion element to convert the first excitation light into a light of a different specific wavelength, and a second planar wavelength conversion element to convert the second excitation light into a light of a specific wavelength different from the specific wavelength of the first excitation light converted by the first planar wavelength conversion element. In the image projection apparatus, the first planar wavelength conversion element and the second planar wavelength conversion element are arranged at positions different from each other, and the first planar wavelength conversion element and the second planar wavelength conversion element have a first plane and a second plane.

A controller of a projector accepts operation of changing the position of a vertex of a first pattern image projected on a projection surface, deforms the shape of a second pattern image containing a plurality of dots based on the operation, causes the second pattern image to be projected onto the projection surface, generates second correction data for correction of the second image based on a captured image as a result of capture of an image of the projection surface on which the second pattern image has been projected in such a way that the positions of the plurality of dots are corrected, and causes an image corrected by using the generated correction data to be projected onto the projection surface.

A display method includes displaying a first image containing a first portion and a second portion different from the first portion on a screen by a projector, storing information representing a first shape which is a shape of the first portion when the screen is seen from a first direction, and, when the shape of the first portion as seen from the first direction changes to a shape different from the first shape, displaying, by the projector, a second image obtained by performing correction on the first image to make the shape of the first portion as seen from the first direction closer to the first shape, and not performing the correction on the second portion on the screen.
