KR-20260062655-A - ELECTRONIC APPARATUS FOR PROJECTING BY CHANGING A POSITION OF A PORTION OF AN IMAGE AND CONTROL METHOD THEREOF

Abstract

An electronic device is disclosed. The electronic device comprises one or more processors including a memory for storing instructions, a projection unit, a camera, and processing circuitry. When the instructions are executed individually or collectively by one or more processors, the projection unit is controlled to project an image onto a projection area. A captured image of the projection area is obtained through a camera. When an object that obscures the image projected onto the projection area is identified from the captured image, the projection unit is controlled to change the position of a portion of the image based on the area where the object is identified and to project the image.

Description

ELECTRONIC APPARATUS FOR PROJECTING BY CHANGING A POSITION OF A PORTION OF AN IMAGE AND CONTROL METHOD THEREOF } The present disclosure relates to an electronic device and a method for controlling the same, and more specifically, to an electronic device and a method for controlling the same that changes the position of a portion of an image and projects it. With the advancement of electronic technology, electronic devices offering various functions are being developed. In particular, various types of projectors have recently become widespread. A projector is a device that projects images. By projecting light onto a projection area to create an image, it has the advantage of easily enabling large screens compared to other types of display devices. Recently, projectors or accessory devices attached to projectors that detect user touch interactions on a specific area of the projection area are also being developed. However, there is a problem where part of the image being projected onto the projection area is obscured depending on the user's touch interaction.
