Abstract: Various embodiments regarding an electronic device and a content providing method in an electronic device are described. An electronic device according to an embodiment comprises: a communication unit configured to transmit content and receive additional information of the content; a control unit configured to acquire information related to the secondary of the content on the basis of the additional information; and a display unit configured to display the content and the information related to the secondary of the content. Other various embodiments are also possible.

Abstract: A method of an electronic device is provided. The method includes generating a key code by receiving a selection on at least one area from among areas of an image displayed, decrypting an encrypted message included in the image by using the generated key code, and determining whether to output the encrypted message by determining whether a hash code for the decrypted message is identical to a hash code for inputted text information.

Abstract: An apparatus and a method for processing a stereo image are provided. In the method, a first image and a second image are obtained via a first camera module and a second camera module installed spaced by a predetermined distance. When the stereo image is captured, the first image and the second image are alternatively sampled with a predetermined time interval. The sampled at least one first image and the sampled at least one second image are encoded. Therefore, the stereo image can be compressed with low complexity compared to the case of compressing a stereo image using a 2D image compression technology.

Abstract: A vergence control method for controlling a stereoscopic display is provided. The method comprises reproducing a stereoscopic image, receiving an input signal for vergence view adjustment of the stereoscopic image, and adjusting a vergence view so that a position corresponding to the received input signal becomes the vergence view by removing a parallax of image frames of the position.
