Abstract: Provided is a video telephony apparatus and method for mobile terminals. The video telephony apparatus includes a controller, a display unit, a codec, and a content controller. The controller exchanges protocol signals for a video call with the other party terminal, and demultiplexes a moving image and a voice that are received from the other party terminal. The display unit displays the received moving image, and the codec plays the received voice. The content controller manages Right Objects (ROs) of multimedia contents received from the other party terminal, and captures the displayed moving image and the played voice according to the ROs. Accordingly, it is possible to protect portrait rights during the video call.

Abstract: 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.

Abstract: 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.

Abstract: 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.
