Abstract
A projector is provided, which has a plurality of operating modes, including a first operating mode in which a beam of electromagnetic waves is emitted by the projector. In addition, a detection unit is configured in such a way that in the first operating mode of the projector the presence of an object in the optical path of the beam is detected. Moreover, the projector includes a processing unit which is developed to switch from the first operating mode to a second operating mode that differs from the first operating mode when an object is detected in the optical path of the beam.

A projector adapted to operate in a plurality of operating modes, in which a first operating mode corresponds to the projector emitting a beam of electromagnetic waves, the projector comprising:
- a detector unit that in the first operating mode of the projector is configured in such a way that a presence of an object in an optical path of the beam is detected;
- and
- a processing unit that switches from the first operating mode to a second operating mode that differs from the first operating mode when the object is detected in the optical path of the beam.
A mobile telephony device, comprising:
- a projector adapted to operate in a plurality of operating modes, in which a first operating mode corresponds to the projector emitting a beam of electromagnetic waves, the projector including:
- a detector unit that in the first operating mode of the projector is configured in such a way that a presence of an object in an optical path of the beam is detected, and
- a processing unit that switches from the first operating mode to a second operating mode that differs from the first operating mode when the object is detected in the optical path of the beam
A method for a contact-free control of a projector, the projector adapted to operate in a plurality of operating modes, in which a first operating mode corresponds to the projector emitting a beam of electromagnetic waves, the projector including a detector unit that in the first operating mode of the projector is configured in such a way that a presence of an object in an optical path of the beam is detected, and the projector including a processing unit that switches from the first operating mode to a second operating mode that differs from the first operating mode when the object is detected in the optical path of the beam, the method comprising:
- generating a signal using the detector unit when the detector unit detects the presence of the object in the optical path of the beam;
- conveying the signal to a processing unit;
- and
- changing a current operating mode of the projector by the processing unit on the basis of the signal.
