Abstract:
PURPOSE: A method for controlling an output level of a voice signal during a video call and a device therefor are provided to automatically control an output level of received voice in consideration of the distance between a user and a terminal and a surrounding noise. CONSTITUTION: An video signal preprocessing unit(131) processes an input video signal used for a video call and a received video signal received from a counterpart terminal. A voice signal preprocessing unit(191) processes an input voice signal used for a video call and a received voice signal received from a counterpart terminal. A face region confirming unit(132) confirms the size of the face region included in the input video signal. A voice signal output level control unit(21) controls an output level of the received voice signal in consideration of the distance to a user based on the size of the face region.
Abstract:
PURPOSE: An adaptive gesture recognition apparatus in a portable terminal and method thereof are provided to improve the recognition accuracy of movement by modeling gestures into plural classes. CONSTITUTION: A portable terminal collects situation information(403). The portable terminal displays one or more gesture function icons(405). The portable terminal determines the gesture of a user through sensor measurement values(407). The portable terminal determines the functions(409). The portable terminal executes the determined function(411).
Abstract:
PURPOSE: An apparatus and a method thereof for reducing the power consumption in order to solve the electric power consumption problem in a standby state are provided to control the operation of sensors which determine the state of the portable terminal. CONSTITUTION: A state determining unit(104) independently includes an application processing unit to control an application. The state determining unit is woken up in a standby state. The state determining unit determines the state of a portable terminal. In case the portable terminal escapes a standby state, the state determining unit wakes up the application processing unit. The application processing unit sleeps at specific interval.
