Electronic apparatus for compensating external areas resulting from keystone correction and controlling method thereof

Abstract

An electronic apparatus is provided. The electronic apparatus includes: a projector configured to project an image with a specified resolution, a camera, and at least one processor, comprising processing circuitry, connected to the projector and the camera and configured to control the electronic apparatus, wherein at least one processor, individually and/or collectively, is configured to: perform keystone correction for a first image, control the projector to project an image of the specified resolution in which the keystone-corrected first image is included in one area and a second image is included in a remaining area to a projection area, obtain a captured image by photographing the projection area and an external area of the projection area through the camera, adjust a pixel value of the second image based on first pixel information corresponding to the remaining area in the captured image and second pixel information corresponding to the external area of the projection area, and control the projector to project an image of the specified resolution in which the keystone-corrected first image is included in the one area and the second image with the adjusted pixel value is included in the remaining area to the projection area.
