An electronic device and an method of operating an electronic device according to various example embodiments include: acquiring one of a plurality of pieces of identification information which are already registered; setting one of a plurality of function sets which are already registered based on the acquired identification information; and allowing access based on the set function set.

Electronic device and operating method thereof

Provided is a method and apparatus for video telephony in a portable terminal. In the method, all image frames received from a video telephony counterpart terminal are decoded when a video telephony event is detected. Thereafter, it is determined if the received image frames are accumulated in a buffer of the portable terminal. Thereafter, only a portion of the decoded image frames are selected and displayed when the received image frames are accumulated in the buffer.

Method and apparatus for video telephony in portable terminal

Provided are an apparatus and methods for recovering video information when operating in an area that impairs an electromagnetic field of a transmit/receive signal during a video telephony of a portable terminal. A method of which includes determining a number of buffers for storing intra coded (I) frames to be received, transmitting the number of the buffers to a counterpart terminal together with a VFU signal, acquiring video information by storing I frames received from the counterpart terminal, and generating video frames using the acquired video information.

Methods and apparatus for recovering video information in a mobile communication system

A method for trembling compensation of a portable terminal includes obtaining a first image having lower brightness and a second image having higher brightness, the lower and higher brightness being different, by adjusting an iris when an image photograph event occurs, computing motion vectors at respective regions of the first and second images and generating search matrices of the respective regions of the first and second images, searching locations having a similar saturation in the search matrices of the first and second images, and compensating saturation and brightness of the first image having a lower brightness, using the searched locations.

Apparatus and method for compensating trembling of a portable terminal

A method of setting a timer value and a counter value depending on Radio Signal Strength (RSS) information according to a communication protocol is provided. In the method of determining the counter value and the timer value of a Mobile Station (MS) in a protocol negotiation process includes measuring a Round Trip Delay (RTD) and an RSS with respect to a counterpart MS, determining a timer value and a counter value according to the measured RTD and RSS, and exchanging a signaling message according to the determined timer value and counter value.
