엑스선영상장치는, 촬영영역(FOV, field of view)의투영영상에대해역투영영상을생성하는역투영영상생성부; 및역투영영상의주파수성분에기초하여주파수별복원영상을생성하고, 주파수별복원영상을합성하여투영영상에대한복원영상을생성하는영상복원부; 를포함할수 있다. 이와같은엑스선영상장치및 엑스선영상장치의제어방법에의하면, 대상체의전부또는일부영역에대해복원영상을생성할수 있다. 특히, 대상체내부의일부분의정보를알 수없는경우또는촬영영역(FOV, field of view)이대상체내부의일부분만을포함하는경우에도복원영상을생성할수 있으며, 이에따라대상체에대한엑스선조사범위를축소하여엑스선의피폭량을감소시킬수 있다. 또한, 영상복원을위한연산량및 연산의복잡도를감소시켜복원영상의생성시간을단축시킬수 있다.
Abstract:
PURPOSE: A ping interval setting method of a portable terminal and an apparatus thereof are provided to perform a ping test by calculating an optimum ping interval. CONSTITUTION: If a ping test is confirmed as success, a control unit(10) checks a count table. The control unit confirms whether a short interval count of the set ping interval is 0 or not. The control unit resets a ping interval. If the ping test is confirmed as failure, the control unit checks the count table. The control unit confirms whether a short interval count of the set ping interval is 0 or not. The control unit resets a ping interval.

Abstract:
A moving picture file playback method and an apparatus thereof by playing back a specified section with referenced information are provided to replay a specified section easily, to use the memory of the moving picture file device efficiently and to supply the moving picture file information effectively with reference to the information stored in an index file. A moving picture file playback apparatus stores and replays multiple moving picture files. The moving picture file playback device generates and stores at least one index file(300) according to user's request, and provides more than one index file list. The moving picture file playback device detects an original file path(305) information included in the selected index file by a user among more than one pre-stored index files and searches the corresponding moving picture file. The moving picture file playback device replays and outputs the specified section corresponding to the start time(301) information and section information(303) included in the selected index file among the whole playback section of the searched moving picture files.

Abstract:
An apparatus and a method for transceiving moving picture data through LAN(Local Area Network) are provided to perform reproduction and reception of a moving picture in a remote mobile phone, thereby sharing the moving picture and simultaneously reproducing the moving picture between mobile phones. A method for transceiving moving picture data through LAN includes a close range communication module, a moving picture reproducing unit(108,111), and a control unit(103,113). The LAN module performs close range communication. The moving picture reproducing unit reproduces a moving picture file. The control unit operates the moving picture reproducing unit, generates an arbitrary video file and an arbitrary audio file, and transmits an arbitrary file generated after delaying as much as transmitting time according to moving picture bit rate computation through the close range communication module.
Abstract:
본 발명은 블루투스 모듈과 같은 근거리 통신용 모듈이 탑재된 이동 단말기를 이용하여 근거리 협대역 통신망을 통해 파일 기반의 동영상을 실시간으로 스트리밍할 수 있도록 하기 위한 방안을 제공하고자 한다. 특히, 본 발명은 ISO/IEC의 MPEG(Moving Picture Experts Group)에서 규정하는 시스템 형식이나 파일형식으로 파일 형태로 저장된 오디오 비쥬얼(AV : Audio Visual) 데이터를 근거리 통신망에 연결된 원격 이동 단말기로 일부 데이터를 전송하여 재생 시작한다. 이후, 나머지 데이터를 소정의 크기의 파일로 분할하여 전송하여, 원격 휴대폰에서 동영상 재생과 수신을 병렬적으로 실행할 수 있도록 하는 방안을 제공한다. 블루투스, 동영상 데이터 전송, 카메라.
