An apparatus and a method for automatically controlling a screen brightness of an AVN system are provided to automatically change screen brightness in a user customized manner in a response to a change in illumination outside the vehicle. The apparatus include a screen brightness control module that controls such that a screen brightness of a display provided in the AVN system is automatically changed according to a change in the illumination data received from the illumination sensor, based on a default matching relationship between previously stored illumination data and screen brightness and a gain adjustment module that generates a new customized matching relationship by correcting the screen brightness matched to each illumination data based on the default matching relationship in accordance with an input of a user who adjusts to enhance or weaken the screen brightness and provides the screen brightness control module with the new customized matching relationship for screen brightness control.

Apparatus and method for automatically controlling screen brightness of AVN system

An apparatus for controlling a display includes a controller to set a relationship index indicating relationship between selected content, which is selected through an input of a user, of the at least one content, and remaining content of the at least one content, and arrange an output screen of the output device, based on the relationship index, such that content useful to a user as well as content desired by the user is determined and provided, thereby improving the convenience of the user.

Apparatus and method for controlling a display

A screen control apparatus of a vehicle and a method thereof are provided. The screen control apparatus includes: a sensing device that measures illumination; a brightness determining device that determines a brightness degree corresponding to the illumination from one or more illumination measurement data; and a controller that controls a screen brightness of a display depending on the determined brightness degree. The controller controls the screen brightness of the display, whenever the brightness degree is changed.

Screen control apparatus of a vehicle and a method thereof

A screen control apparatus of a moving object, a method thereof, and a system thereof are provided. The screen control apparatus includes: a communication device that receives illumination measurement data measured by at least one information providing moving object from a server; an illumination score calculating device that calculates an illumination score for the received illumination measurement data; an illumination determining device that selects reference illumination measurement data depending on the illumination score and determine illumination; and a controller that controls a screen brightness on the basis of the determined illumination.

A sound signal processing system for achieving a handsfree function irrespective of positions of passengers using one microphone includes a microphone including a plurality of cores, and a head unit for generating a plurality of beams using a plurality of analog signals inputted from each of the plurality of cores, searching for a sound signal through each of the plurality of beams to select one beam, and outputting a sound signal corresponding to the selected beam.

In-vehicle voice reception system using audio beamforming and method for controlling thereof

A multimedia terminal device for high-speed charging that allows for high-speed charging of a portable electronic device connected to a multimedia terminal and a method of controlling the same are provided. The multimedia terminal device includes a power converter that is configured to convert a voltage from a battery to a voltage for the high-speed charging and to supply the converted voltage to the multimedia terminal. In addition, a switching circuit is configured to select a high-speed charging mode when an engine is driven and a low-speed charging when the engine is stopped.

Multimedia terminal device for high-speed charging and method of controlling the same

A reconfigurable semiconductor device is disclosed. The semiconductor device includes a substrate, a first insulating material formed on the substrate, two channels having different polarities, a plurality of terminal electrodes formed on the insulating material and coupled in common with the channels at their opposite ends, a second insulating material formed on the terminal electrodes, and a control gate formed on the second insulating material. The channels have different polarity and a charge storage layer is formed inside the second insulating material. The control gate is applied with a forward bias or a reverse bias and then the bias is cut off. The voltage-current characteristics of the semiconductor device are changed according to an electrical charge created in the charge storage layer.
