Title:
撮像装置のレンズ駆動方法及び撮像装置並びにカメラシステム
Document Type and Number:
Japanese Patent JP4986346
Kind Code:
B2
Abstract:
When an object image at a preset position is zoomed in at a target magnification by a zoom lens, the focus point position N of the object image at the zoom position Z1 of the target magnification is calculated. In addition, the mutual relation value (interior division ratio x:y) between the tracking curve I, II and the focus point position is calculated and the position of the focus lens is controlled so that the mutual relation value is kept with respect to the tracking curve when zoom-in is carried out. Accordingly, an object image in focus can be picked up at all times even during zooming.
