Electronic apparatus and controlling method thereof

A method for controlling an electronic apparatus that includes a projection part configured to project images on a projection surface, and at least one sensor configured to obtain data corresponding to the projection surface, the obtained data including infrared data obtained from infrared radiation (IR) reflected from the projection surface and data not obtained from IR reflection, the method comprising:

• controlling the projection part to project a test image on the projection surface;
• obtaining, based on data not obtained from IR reflection included in data corresponding to the projection surface obtained by the at least one sensor while the test image is projected on the projection surface, a first area on the projection surface;
• obtaining, based on infrared data included in data corresponding to the projection surface obtained by the at least one sensor, a second area on the projection surface, the second area corresponding to an area on the projection surface on which an image is projectable by the projection part;
• and
• obtaining a projection area on the projection surface based on the first area and the second area.

A non-transitory computer-readable storage medium which stores computer instructions for an electronic apparatus to perform an operation when executed by a processor of the electronic apparatus including a projection part configured to project images on a projection surface, and at least one sensor configured to obtain data corresponding to the projection surface, the obtained data including infrared data obtained from infrared radiation (IR) reflected from the projection surface and data not obtained from IR reflection, the operation comprising:

• controlling the projection part to project a test image on the projection surface;
• obtaining, based on data not obtained from IR reflection included in data corresponding to the projection surface obtained by the at least one sensor while the test image is projected on the projection surface, a first area on the projection surface;
• obtaining, based on infrared data included in data corresponding to the projection surface obtained by the at least one sensor, a second area on the projection surface, the second area corresponding to an area of the projection surface on which an image is projectable by the projection part;
• and
• obtaining a projection area on the projection surface based on the first area and the second area.
