Abstract
The disclosure relates to a projector capable of adjusting a user touch area by adjusting an IR irradiation angle and a method of operating the same. The projector may irradiate IR to generate an IR irradiation area in a horizontal direction on a projection plane, determine whether IR reflection is detected in the IR irradiation area in a predetermined operation mode, and based on IR reflection being detected, adjust an IR irradiation angle so that IR reflection is not detected in the IR irradiation area.
Claims20
A projector comprising:
- a projection unit comprising circuitry and configured to project an image onto a projection plane;
- an infrared (IR) emitter comprising circuitry and configured to generate an IR irradiation area in a horizontal direction on the projection plane;
- at least one sensor configured to sense the projection plane or the IR irradiation area;
- a memory storing at least one instruction;
- and
- at least one processor, comprising processing circuitry, electrically connected to the projection unit, the IR emitter, the at least one sensor and the memory, and individually and/or collectively, configured to execute the at least one instruction, and to cause the projector to:
- determine whether IR reflection is detected in the IR irradiation area in a specified operation mode;
- and
- based on IR reflection being detected, control the projector to adjust an irradiation angle of the IR emitter or adjust a height of the IR emitter so that IR reflection is not detected in the IR irradiation area.
A method of operating a projector, comprising:
- irradiating IR to generate an IR irradiation area in a horizontal direction on a projection plane;
- determining whether IR reflection is detected in the IR irradiation area in a specified operation mode;
- and
- based on IR reflection being detected, adjusting an irradiation angle of an IR emitter or adjusting a height of the IR emitter so that IR reflection is not detected in the IR irradiation area.
