  • Patent number: 10750144
    Abstract: A smart lighting device includes an illumination module, an image projection module and a projection mode switching module. The image projection module is pivoted to the illumination module and has a plurality of operation modes. The image projection module rotates relative to the illumination module and is switched among a standby mode and the operation modes. The projection mode switching module is configured to sense a rotation angle of the image projection module with respect to the illumination module. A brightness value of the illumination module and an image frame of the image projection module are adjusted according to the rotation angle.

  • Patent number: 10437140
    Abstract: A projection device includes a projection module and a first camera module. The projection device has a first optical axis and configured to form a projection area, wherein a projection of the first optical axis on an X-Z plane of the projection device is perpendicular to an X-Y plane on which the projection area is formed. The first camera module is disposed on a side of the projection module and includes a second optical axis, wherein the first camera module is configured to form a first shooting area, the second optical axis forms a first angle ??1 with respect to the first optical axis, the projection area at least partially overlaps the first shooting area to form an overlapping area, and the first angle ??1 is a function of a distance between the projection module and the first camera module.

  • Patent number: 10338460
    Abstract: A projection apparatus includes an image projection module, a lens module and a light emitting module. The image projection module has a first optical axis and forms a projection area on a bearing surface. A projection of the first optical axis on an X-Z plane is perpendicular to an X-Y plane on which the projection area is formed. The lens module comprises N cameras, each having a corresponding second optical axis and being for forming a shooting area. The N second axes are tilted to the first optical axis and have an angle with respect to the X-Z plane. The light emitting module includes M light emitting components, each having a corresponding third optical axis and being for forming a sensing area. The projection area, the N shooting areas and the M sensing areas are at least partially overlapped with each other to form a rectangular shooting sensing area.

  • Publication number: 20170344190
    Abstract: A computer system having a sensing function includes a base, a first light emitting assembly and a second light emitting assembly. The base is disposed on a bearing surface. The first light emitting assembly is disposed in the base and has a first optical axis. The second light emitting assembly is disposed in the base and has a second optical axis. A distance between the firs optical axis and the second optical axis is D. An inner edge of a first light source emitted by the first light emitting assembly and an inner edge of a second light source emitted by the second light emitting assembly intersect at a point on the bearing surface, thereby forming an irregular-shaped sensing region having a boundary passing through the point. A length of a shortest side of the irregular-shaped sensing region is less than or equal to 2D.
