Abstract
본 발명은 카메라의 줌 표시 장치 및 방법을 공개한다. 그 장치는 제1제어신호에 응답하여 줌 렌즈로부터 입력된 영상을 전기적인 신호로 변환하고, 변환된 신호를 출력하는 카메라 신호처리수단과, 변환된 신호를 입력하여 신호처리후 비디오 온 스크린 디스플레이 신호와, 제2제어신호에 응답하여 영상의 화각에 대한 크기 및 줌 렌즈의 위치를 나타내는 신호인 화각 온 스크린 디스플레이 신호를 믹싱하여 출력하는 신호처리수단과, 및 제1제어신호를 출력하고, 줌 렌즈의 위치를 검출하여 위치를 조절하고, 줌 렌즈의 적어도 하나 이상의 위치들에 대응하는 각각의 예상 화각의 크기를 결정하여 제2제어신호로 출력하는 제어수단을 구비하는 것을 특징으로 하고, 그 방법은 줌 렌즈의 현재 위치를 계산하는 위치계산단계와, 줌 렌즈의 위치에 따라 수평단위선과 수직단위선의 조합으로 화각의 면적을 계산하는 화각 계산단계와, 및 화각을 온 스크린 디스플레이하는 디스플레이 단계를 구비하는 것을 특징으로 하고, 줌 렌즈의 배율뿐만 아니라, 촬영하고자 하는 대상물의 유효화각, 즉, 예상되는 촬영 가능 영역을 사용자에게 제공함으로서, 사용자의 직감 혹은 감각적인 경험이 없어도 그에 준하는 촬영을 할 수 있도록 하기 때문에, 사용자가 촬영하기 편리하여, 촬영의 효율적인 면이 증대하는 효과가 있다.The present invention discloses a zoom display device and method of a camera. The apparatus converts an image input from a zoom lens into an electrical signal in response to the first control signal, and camera signal processing means for outputting the converted signal, and a video on-screen display signal after inputting the converted signal and processing the signal. And signal processing means for mixing and outputting an angle of view on-screen display signal, which is a signal indicating a magnitude of an angle of view of the image and a position of a zoom lens in response to the second control signal, and outputting a first control signal, the zoom lens And controlling means for detecting a position of the lens and adjusting the position and determining a magnitude of each expected angle of view corresponding to at least one or more positions of the zoom lens and outputting the second control signal. The position calculation step of calculating the current position of the zoom lens, and the area of view angle is calculated by the combination of the horizontal unit line and the vertical unit line according to the position of the zoom lens. Is characterized by comprising an angle of view calculation step and a display step of on-screen display of the angle of view, by providing the user with not only the magnification of the zoom lens, but also the effective angle of view of the object to be photographed, that is, the expected recordable area. Since the user can shoot according to the user's intuition or sensational experience, it is convenient for the user to shoot, thereby increasing the effective aspect of the shooting.
