Description

[Technical Field] The disclosure relates to an electronic device including a three-dimensional (3D) display that displays a 3D screen, and a method for operating the same. [Background Art] The development of technology for electronic devices has led to the widespread use of various types of electronic devices, such as mobile communication terminals, personal digital assistants (PDAs), electronic notebooks, smartphones, tablet personal computers (PCs), and wearable devices. For example, an electronic device focuses on enabling a viewer to watch an image where a stereoscopic effect is implemented from a free position without the hassle of wearing glasses, beyond the limitations of the existing 3D stereoscopic imaging scheme which requires wearing glasses. A 3D display that displays glasses-free 3D stereoscopic images is implemented by fusing multi-viewpoint images into one, which provides different images to the left and right eyes using a viewer's eye parallax to achieve the stereoscopic effect. Further, for example, an electronic device may provide virtual reality (VR), which allows a user to have a real-life experience in a virtual world created by a computer, augmented reality (AR), which displays virtual information (or objects) added to the real world, and mixed reality (MR), which is a blend of VR and AR. The electronic device provides the user with 3D stereoscopic images corresponding to VR, AR, or MR. The above information is presented as related art only to assist with an understanding of the disclosure.
