Abstract: Disclosed is a system of a dynamic range three-dimensional image, including: an optical detector including a gain control terminal capable of controlling an optical amplification gain; a pixel detecting module for detecting a pixel signal for configuring an image by receiving an output of the optical detector; a high dynamic range (HDR) generating module for acquiring a dynamic range image by generating a signal indicating a saturation degree of the pixel signal and combining the pixel signal based on the pixel signal detected by the pixel detecting module; and a gain control signal generating module generating an output signal for supplying required voltage to the gain control terminal of the optical detector based on the magnitude of the signal indicating the saturation degree of the pixel signal.

Abstract: Provided is an apparatus and method for measuring IQ imbalance, and in particular, is an apparatus and method for measuring IQ imbalance for an optical receiver. The apparatus for measuring IQ imbalance for an optical receiver includes a light generating unit generating optical and reference signals to provide the optical and reference signals to an optical receiver, a graph creating unit creating a Lissajous figure by using an in-phase (I) signal and a quadrature-phase (Q) signal output from the optical receiver in response to the optical and reference signals, and a calculating unit calculating IQ imbalance for the optical receiver with reference to the Lissajous figure.

Abstract: An electronic apparatus and a method of controlling the electronic apparatus are provided. The method includes: receiving a voice command; and if the voice command is a first voice start command, changing a mode of the electronic apparatus to a first voice task mode in which the electronic apparatus is controlled according to further voice input, and if the voice command is a second voice start command, changing the mode of the electronic apparatus to a second voice task mode in which the electronic apparatus is controlled according to the further voice input received via an external apparatus which operates with the electronic apparatus. Therefore, providing efficiency and flexibility in controlling the electronic apparatus by using a microphone of the electronic apparatus or a microphone of the external apparatus.

Abstract: A control method and display apparatus for providing various types of content is provided. The display apparatus includes a display unit which displays an image of contents; a storage unit which stores information regarding the contents; a UI generation unit which generates UIs regarding the contents; and a controller which shuts down a first content being executed, storing information regarding the shut down first content and controls generation and display of a UI regarding the first content on the display unit, when running a second content different from the first content, while the first content is running. The control method includes running contents and displaying the contents; running a second content that is different from a first content being run, according to a user input; shutting off the first content before running the second content; storing the first content; and generating and displaying a UI regarding the first content.
