A projector apparatus includes a projection unit and a controller. The projection unit projects projection video of an image at a set angle of view on a projection surface in accordance with a video signal indicating the angle of view of the image including an object. The controller performs video signal processing for changing a position or size of the object in the image and controls the position or size of the projection video on the projection surface. In a case where the position or size of the object is to be changed by the video signal processing, when a resolution of the projection video of the changed object is less than a predetermined value, the controller controls the projection unit to decrease the angle of view so that the resolution of the projection video is equal to or greater than the predetermined value, and the controller sets the size of the object in the image by the video signal processing.

Projection apparatus

A projection device according to the present disclosure includes a sensor unit (for example, a camera), a detection unit, a controller and a projection unit. The sensor unit detects an object. The detection unit detects a moving object (for example, a person), a first object, and a second object based on a signal output from the sensor unit. The controller generates a projection image such that a first image corresponding to the first object is projected on a first projection region and a second image corresponding to the second object is projected on a second projection region. In this case, the first image is determined based on a position of the moving object, and the second image is determined without depending on a position of the moving object. The projection unit projects the projection image.

Projection device and projection method, for projecting a first image based on a position of a moving object and a second image without depending on the position

A user interface device for detecting an operation, by a finger of a user, on an operation member presented on a projection surface includes a distance detector for detecting a distance to the projection surface, and a distance to the finger, and a controller for detecting the operation based on the distances detected by the distance detector. When presence of the finger between the projection surface and the distance detector is determined, the controller calculates a normal vector of the projection surface based on distances from the distance detector to positions of at least three points on a surface of the projection surface and a distance from the distance detector to the finger, and detects, based on the normal vector, presence or absence of an operation on the operation member.
