Abstract

본 발명은 동화상전화기에 관한 것으로, 화상통화하는 상대방의 영상이 정확하게 포커싱(Focusing)되지 않을시 국선을 통해 상대방 카메라의 줌인(Zoom In), 줌 아웃(Zoom Out)을 제어하여 화상통화의 신뢰성을 향상시키도록 한 동화상전화기의 상대방 카메라 제어방법 및 그 장치에 관한 것이다.The present invention relates to a video phone, and when the video of the other party to the video call is not focused correctly (Focusing) by controlling the zoom in (Zoom In), Zoom Out of the camera of the other party through the trunk line reliability of the video call The present invention relates to a method of controlling a counterpart camera of a moving picture telephone and an apparatus thereof.

본 발명은 동화상전화기를 이용하여 화상통화하는 상태에서 상대방의 영상이 카메라로 부터 멀어지거나 근접되어 상대방의 영상 유효범위를 벗어나 포커싱이 정확하게 이루어지지 않을시 국선을 통해 상대방의 영상을 원하는 상태로 조정하므로 양질의 통화를 수해한다.The present invention adjusts the video of the other party to the desired state through the CO line when the video of the other party is far away from the camera or close to the camera while the video call is made using the videophone. Receive quality calls.

Claims (2)

동화상전화기에 있어서, 국선을 통해 특정 상대방과 통화로를 연결하여 화상통화하는 상태에서 DSP는 국선을 통해 특정 상대방과 통화로를 연결하여 화상통화하는 상태에서 DSP는 국선을 통해 인가되는 제어신호를 분석하는 제1단계와, 상기 제1단계 수행후 분석된 제어신호가 사용자의 영상을 조정하기 위한 카메라 줌 인 또는 줌 아웃 신호 인가의 여부를 판단하는 제2단계 및 상기 제2단계에서 분석된 제어신호가 사용자의 영상을 조정하기 위한 카메라 줌 인 또는 줌 아웃 신호이면 상기 DSP는 모터측에 소정의 제어신호를 인가하여 카메라를 줌 인 또는 줌 아웃시켜 사용자의 영상을 조정하는 제3단계를 포함하는 것을 특징으로 하는 동화상전화기의 상대방 카메라 제어방법.In a moving picture telephone, the DSP analyzes the control signal applied through the CO line while the DSP makes a video call by connecting a call to a specific party through a CO line. And a second step of determining whether the control signal analyzed after the first step is applied to the camera zoom in or zoom out signal for adjusting the user's image and the control signal analyzed in the second step. Is a camera zoom-in or zoom-out signal for adjusting a user's image, the DSP may include a third step of adjusting a user's image by applying a predetermined control signal to the motor side to zoom in or zoom out the camera. The other party camera control method of a video telephone. 동화상전화기에 있어서, 사용자의 송신음성을 입력하는 음성입력수단과 수신되는 상대방의 음성을 출력하는 음성출력수단과 사용자의 영상을 입력하는 영상입력수단과 수신되는 상대방의 영상을 출력하는 표시수단 및 국선과 접속되어 송수신되는 영상신호 및 음성신호를 인터페이싱 하는 인터페이스수단을 구비하되, 국선으로 부터 인가되는 제어신호를 분석하여 상기 영상입력수단의 줌 인 또는 줌 아웃을 조정하기 위한 제어신호를 출력하는 DSP와 상기 DSP의 제어신호레 따라 상기 영상 입력수단의 줌 인 또는 줌 아웃을 조정하는 모터를 더 구비하는 것을 특징하는 동화상전화기의 상대방 카메라 제어장치.In a moving picture telephone, voice input means for inputting the user's transmission voice, voice output means for outputting the voice of the other party, video input means for inputting the user's image, display means for outputting the image of the other party and trunk line And an interface means for interfacing a video signal and an audio signal transmitted / received, the DSP outputting a control signal for adjusting the zoom-in or zoom-out of the video input means by analyzing a control signal applied from a trunk line; And a motor for adjusting zoom in or zoom out of the video input means according to the control signal of the DSP. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
