Abstract
An electronic apparatus includes a projection part, an acceleration sensor, a plurality of distance sensors arranged on one surface of the electronic apparatus facing a projection surface, a memory storing at least one instruction, and a processor, wherein the plurality of distance sensors are arranged side by side on left and right sides on one surface of the electronic apparatus, and are arranged to be rotated by a first angle to face one another, and the processor is configured to calculate a first rotation angle and a second rotation angle for the direction of gravity of the electronic apparatus based on sensing values acquired by using the acceleration sensor, calculate a third rotation angle of the electronic apparatus for the projection surface based on sensing values acquired by using the plurality of distance sensors and the first angle, and perform keystone correction based on the first to third rotation angles.
