US 2024/0195946 A1 · ELECTRONIC APPARATUS AND CONTROL METHOD THEREOF

Abstract

An electronic apparatus is disclosed. The electronic apparatus comprises: an acceleration sensor; a distance sensor; an image projector; and at least one processor connected to the acceleration sensor, the distance sensor, and the image projector to control the electronic apparatus, wherein the processor controls the image projector to project an image onto a projection surface, acquires vertical distortion information corresponding to a projected image on the basis of slope information of the electronic apparatus acquired by the acceleration sensor and distance information to the projection surface acquired by the distance sensor, acquires vertical keystone correction information on the basis of the vertical distortion information, when a first user command for keystone correction is received, performs keystone correction for the image on the basis of vertical keystone correction information corresponding to the first user command and the acquired vertical keystone correction information, and controls the image projector to project a keystone-corrected image.
