Electronic apparatus and control method thereof

A control method of an electronic apparatus, the control method comprising:

• identifying a first projection position according to an environmental illuminance value based on first data and a first brightness value of a projection surface;
• obtaining a second brightness value corresponding to a brightness of a projection image at the first projection position;
• obtaining a third brightness value corresponding to a brightness of a projection area based on second data while the projection image is being output;
• and
• outputting the projection image at a second projection position determined based on the second brightness value and the third brightness value.

An electronic apparatus comprising:

• a sensor;
• a projector configured to output light;
• a moving member;
• memory storing instructions;
• and
• at least one processor,
• wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic apparatus to:
• identify a first projection position according to an environmental illuminance value based on first data obtained through the sensor and a first brightness value of a projection surface;
• move, by the moving member, to the first projection position;
• obtain brightness information while projecting at the first projection position;
• determine to move to a second projection position based on the brightness information;
• and
• move, by the moving member, to the second projection position.
