    Abstract: An image magnification control device for a camera having a photographic lens. The image magnification control device includes a first detector that functions to detect a focal length "f0" of the photographic lens. A distance "X0" between a rear focal point of the photographic lens and an image taking plane of the camera is then determined based on a delivery-amount of a focusing lens of the photographic lens and the detected focal length "f0". A second detector detects a defocusing amount "dx" by analyzing a light passed through the photographic lens, in which the defocusing amount "dx" represents a displacement of an image formed by the photographic lens from the image taking plane. An image magnification "m0" is determined based on a formula "m0=X0/f0", while a control focal length "f1" is calculated based on a formula "f1=(f).sup.2 .multidot.m0)/(X0+dx)". The focal length of the photographic lens is thus controlled so as to meet the control focal length "f1".

    Abstract: A zoom optical system (25) is associated with an image sensor (46), which is disposed behind the zoom optical system for picking up an object (6). The zoom optical system is focussed by use of a photoelectric signal from the image sensor. In a setup mode, the zoom optical system is zoomed from a first magnification to a preset magnification. The zoom optical system has been set at the first magnification. The preset magnification is adapted to focussing. The zoom optical system is focussed in accordance with the photoelectric signal generated while the zoom optical system has the preset magnification. The zoom optical system is zoomed back from the preset magnification to the first magnification, while keeping the zoom optical system in-focus. The zoom optical system becomes in-focus at the first magnification in a manner in which the zoom optical system is in-focus at the preset magnification.

A defocus amount "dx" of an object is detected by analyzing a light that passed through the photographic lens. A control focal length "f1" required to maintain an image magnification is calculated that is based upon the detected defocus amount "dx". Thereafter, it is determined whether the control focal length "f1" falls within a range between a tele terminus focal length "ft" of the photographic lens and a wide terminus focal length "fw" of the photographic lens. A first controller controls a focal length of the photographic lens so as to meet the control focal length "f1" when it is determined that the control focal length falls within the range, while a second controller controls the focal length of the photographic lens so as to meet one of the tele terminus focal length "ft" and the wide terminus focal length "fw" when it is determined that the control focal length "f1" goes beyond the range.
