Abstract

본 발명은 인너 포커스 방식에서 줌 렌즈의 트래킹을 조정하는 방법으로서, 베리에이터 렌즈(3)를 소정 거리씩 순차적으로 이동하면서 이동된 베리에이터 렌즈 (3)에 대한 포커스가 맞추어지도록 마스터렌즈(5)를 이동시키고 그 이동 거리를 각각 검출하는 단계(41, 42, 43, 44)와; 상기 베리에이터 렌즈(3)의 이동에 대하여 초점이 맞추어지도록 상기 마스터 렌즈(5)가 이동한 거리가 설계치의 한계 거리내에 있는가를 판단하여 줌 렌즈의 폐기 여부를 결정하는 단계(45, 46, 47)와; 상기 베리에이터 렌즈(3)의 이동에 대하여 초점이 맞추어지도록 상기 마스터 렌즈(5)가 이동한 거리가 설계치의 한계 거래내에 있으면, 상기 베리에이터 렌즈의 이동에 대하여 초점이 맞추어지도록 상기 마스터 렌즈가 이동한 거리를 저장하여 줌 렌즈이 사용시 상기 베리에이터 렌즈이 이동에 따라 상기 저장된 거리만큼 상기 마스터 렌즈를 이동시키게 하는 단계(48)를 구비한다.The present invention is a method of adjusting the tracking of a zoom lens in the inner focus method, the master lens (5) so that the focus on the moved variator lens (3) is adjusted while sequentially moving the variator lens (3) by a predetermined distance Moving (41) and detecting the moving distances (41, 42, 43, 44), respectively; Determining whether or not to discard the zoom lens by determining whether the distance traveled by the master lens 5 is within the limit of the design value so that the movement of the variator lens 3 is focused (45, 46, 47). Wow; If the distance traveled by the master lens 5 to be in focus with respect to the movement of the variator lens 3 is within the limit transaction of the design value, the master lens is moved to be in focus with respect to the movement of the variator lens. Storing a distance to cause 48 to move the master lens by the stored distance as the variator lens moves as it is used.

따라서, 본 발명은 베리에이터 렌즈(8)를 와이드 위치로부터 텔레 위치가지 소정 거리씩 이동시키며, 이동될 때마다 마스터 렌즈(5)를 이동시켜 초점이 맞추어지는 마스터 렌즈(5)의 이동 거리를 검출하므로써 베리에이터 렌즈(3)의 이동 거리에 따라 초점을 맞추는데 필요한 마스터 렌즈 (5)의 이동 거리를 정확하게 검출할 수 있다는 효과가 있다.Accordingly, the present invention moves the variator lens 8 from the wide position by a predetermined distance, and moves the master lens 5 every time it is detected to detect the moving distance of the focused master lens 5. Therefore, there is an effect that the movement distance of the master lens 5 necessary for focusing according to the movement distance of the variator lens 3 can be detected accurately.
