본 발명은 영상 촬영이 가능한 이동통신 단말기에 관한 것으로서, 특히, 음성 통화를 위한 기본 폰 모드 이외에 디지털 캠코더 모드, 화상 통신모드 등의 영상 촬영 모드 수행 및 TV/VOD 모드의 모드 수행에 적합한 영상 촬영이 가능한 이동통신 단말기에 관한 것이다.The present invention relates to a mobile communication terminal capable of capturing an image, and more particularly, to perform an image capturing mode such as a digital camcorder mode, a video communication mode, and a TV / VOD mode in addition to the basic phone mode for a voice call. It relates to a possible mobile communication terminal.

근래 들어 데이터 처리속도 및 RF 주파수를 이용한 데이터 전송속도의 증가 등 데이터 전송기술이 발달함에 따라 이동통신 단말기가 단순한 통화 기능에서 TV/VOD(Video On Demand)방식의 영화, 드라마, 비디오 광고 서비스, 비디오 메일 서비스, 멀티미디어 교육 서비스 등의 영상 정보 송수신이 가능해지고 있다.Recently, with the development of data transmission technology such as the increase in data processing speed and data transmission speed using RF frequency, the mobile communication terminal is a simple call function for TV / VOD (Video On Demand) movie, drama, video advertisement service, and video. Image information transmission and reception such as a mail service and a multimedia education service have become possible.

도 1 은 이러한 종래 이동통신 단말기를 설명하기 위한 도면으로, 도시된 단말기는 폴더형 단말기이다.1 is a view for explaining such a conventional mobile communication terminal, the terminal shown is a folder type terminal.

폴더형 이동통신 단말기는 키패드(11)가 형성된 단말기 본체(10)에 폴더(12)가 힌지 등의 체결수단에 의해 상하방향으로 회전 가능하게 결합되고, 폴더(12)의 일면에는 액정표시화면(13, LCD : Liquid Crystal Display)이 형성되어 송수신될 영상정보가 액정표시화면(13)을 통해 출력된다.In the folding mobile communication terminal, the folder 12 is rotatably coupled to the terminal body 10 having the keypad 11 formed thereon by a fastening means such as a hinge, and one side of the folder 12 has a liquid crystal display screen ( 13, LCD (Liquid Crystal Display) is formed and the image information to be transmitted and received is output through the liquid crystal display (13).

그러나, 이러한 이동통신 단말기는 점차로 발전되고 있는 멀티미디어 환경에 부합되지 못하는 문제점이 있다.However, these mobile communication terminals have a problem that does not meet the increasingly developed multimedia environment.

즉, 이동통신 단말기는 음성 통화 이외에 사용자 자신의 영상을 송수신하면서 음성 통화가 이루어지는 화상 통신 및 영상을 촬영하여 바로 디지털 비디오 데이터 송수산하는 영상촬영 통신 등 그 활용 범위가 넓어질 예정이나, 현재 이동통신 단말기는 단말기 본체와 폴더가 힌지에 의해 상하방향으로만 회전 가능하게 결합되고 또한 액정 표시화면으로 출력되는 영상정보는 액정 표시화면의 특성상 한 방향으로만 출력되어 디스플레이됨으로써 단말기 사용자가 액정표시화면을 바라보는 방향에 따라 정보가 역상 또는 회전되게 보이는 문제점이 있어 화상 통신 및 영상 촬영 통신을 위한 디지털 캠코더 장치의 설치가 매우 제한적이다.In other words, the mobile communication terminal is expected to expand its range of applications, such as video communication in which a voice call is made while transmitting and receiving a user's own image in addition to a voice call, and video recording communication in which digital video data is transmitted and received immediately. The terminal is rotatably coupled to the terminal body and the folder in the vertical direction only by the hinge, and the image information output to the liquid crystal display screen is output and displayed in only one direction due to the characteristics of the liquid crystal display screen. There is a problem that the information is reversed or rotated depending on the viewing direction, so that the installation of the digital camcorder device for the image communication and the image photographing communication is very limited.

따라서, 종래의 이동통신 단말기는 데이터 전송기술이 발달함에 따라 요구되는 화상 통신 및 영상 촬영 통신 등의 멀티미디어 환경에 부합되지 못하는 문제점이 있다.Therefore, the conventional mobile communication terminal has a problem that does not meet the multimedia environment, such as video communication and image photographing communication required as the data transmission technology is developed.

이에 본 발명은 음성 통화 이외에 화상 통신 및 영상 촬영통신이 가능하고, 화상 통신 및 영상 촬영통신 과정에서 액정표시화면으로 출력되는 영상 정보가 회전하거나 반전되지 않도록 하는 영상 촬영이 가능한 이동통신 단말기를 제공하는데 그 목적이 있다.Accordingly, the present invention provides a mobile communication terminal capable of video communication and video recording communication in addition to a voice call, and capable of video recording such that video information output on the LCD display is not rotated or reversed during video communication and video recording communication.

Referring to FIG. 3, when the folder 120 is located at the first position, the image information is moved in the first display direction based on the pixel coordinate A corresponding to the upper left endpoint of the LCD screen 121 as a reference coordinate. If the folder is located in the second position, the image information is output in the second display direction using the pixel coordinate B corresponding to the position of the lower right end point of the liquid crystal display as a reference coordinate, and the folder is displayed in the third display direction. When positioned at the position, the controller (not shown) of the terminal corrects the image information so that the image information is output in the third display direction by using the pixel coordinate C corresponding to the position of the lower left endpoint of the liquid crystal display as a reference coordinate to display the image information. Allow the direction to be corrected. .

이와 같이 구성된 본 발명에 따른 영상 촬영이 가능한 이동통신 단말기는 단말기의 모드 상태에 따라 폴더의 위치를 변화시켜 액정 표시화면의 위치가 단말기의 모드 상태에 적합하도록 한다.The mobile terminal capable of capturing images according to the present invention configured as described above changes the position of the folder according to the mode state of the terminal so that the position of the liquid crystal display screen is suitable for the mode state of the terminal.

도 4a를 참조하면 이동통신 단말기가 폰 모드 상태인 경우 폴더(120)를 제1위치에 위치시켜 스피커 유니트(122)와 마이크 유니트(102)가 동일 평면상에 위치되도록 하여 음성 통화가 가능하게 된다.Referring to FIG. 4A, when the mobile communication terminal is in the phone mode, the speaker unit 122 and the microphone unit 102 are positioned on the same plane so that the voice call is possible by placing the folder 120 at the first position. .

그리고, 도4b를 참조하면 이동통신 단말기가 영상 촬영 모드 상태인 경우 폴더(120)를 연결축(110)을 기준으로 제1위치에서 제2위치로 회전 이동시키면 액정표시화면(121)과 CCD 카메라(130)는 동일하지 않은 평면에 위치되고, CCD 카메라에서 촬상한 피사체의 영상정보는 액정표시화면에 출력되어 디스플레이된다.In addition, referring to FIG. 4B, when the mobile communication terminal is in the image capturing mode, when the folder 120 is rotated from the first position to the second position with respect to the connecting shaft 110, the LCD screen 121 and the CCD camera are rotated. 130 is located on the same plane and the image information of the subject photographed by the CCD camera is output and displayed on the liquid crystal display screen.

이때, 액정표시화면(121)의 기준 픽셀 좌표는 보정되어 디스플레이되는 영상정보는 폰 모드 상태와 동일하게 상이 반전되거나 회전되지 않게 된다.At this time, the reference pixel coordinates of the liquid crystal display screen 121 are corrected so that the displayed image information does not invert or rotate the image in the same manner as the phone mode state.
