1. An electronic apparatus comprising:
a memory configured to store an image;
a sensor part including a distance sensor;
a projection part including a projection lens configured to output the image onto a projection surface; and
a processor configured to:
acquire distance information from the electronic apparatus to the projection surface through the sensor part,
acquire output size information of the image based on the acquired distance information,
acquire, through the sensor part, information of the projection surface onto which the image is to be projected, the information of the projection surface including whether the projection surface has a bend,
acquire movement information of the projection lens based on the output size information of the image and the information of projection surface , the movement information being useable to move the projection lens so that the image is projected onto a portion of the projection surface based on the bend of the projection surface, and
control the projection part to output the image onto the projection surface based on the movement information,
wherein the movement information includes a movement direction and a movement distance for moving the projection lens,
wherein the processor is further configured to:
control the projection part to move the projection lens based on the movement direction and the movement distance, and
identify a position of the bend of the projection surface,
divide the projection surface into a first area and a second area based on the position of the bend of the projection surface,
identify the first area as an output area based on a size of a first portion of the image output onto the first area being greater than a size of a second portion of the image output onto the second area,
acquire a size of the output area,
change a size of the image to be projected onto the projection surface based on the size of the output area while maintaining an aspect ratio of the image, and
control the projection part to output the changed image onto the output area.
