Abstract: An augmented reality (AR) device and a method of predicting a pose in the AR device is provided. In the augmented reality (AR) device inertial measurement unit (IMU) values corresponding to the movement of the AR device are obtained at an IMU rate, intermediate 6-degrees of freedom (6D) poses of the AR device are estimated based on the IMU values and images around the AR device via a visual-inertial simultaneous localization and mapping (VI-SLAM) module, and a pose prediction model for predicting relative 6D poses of the AR device is generated by performing learning by using a deep neural network.

Abstract: An apparatus and a method for acquiring depth information are disclosed. To acquire depth information, illumination light of which an amount of light has been modulated by a modulation signal is emitted towards a subject, and an image is captured using an image sensor. An image signal is sequentially acquired from a plurality of rows while shifting a phase of the illumination light at a start exposure time of a row belonging to an intermediate region of a pixel array region of the image sensor. Depth information is calculated from image signals acquired during a plurality of frames while shifting a phase of the modulation signal.
