Abstract
A zoom camera being capable of changing a distance measuring direction to measure an object distance, and more particularly a camera which indicates the distance measuring direction overlapped on an object image in a view finder display. An object image is displayed in a finder display through an optical system, thereby the magnification of the object image in the view finder changes in accordance with a zooming of the camera. An indicator array is arranged on the view finder display, and the distance measuring direction is indicated by an activation of an indicator element of the indicator array located at a corresponding position to an object position in the distance measuring direction. For the purpose of coordinating with the change of magnification of the view image, the corresponding position is determined based on the focal length information obtained by a focal length detector in addition to distance measuring direction information and distance information, each obtained by each of a direction detector and a distance detector.
