Abstract
An automatic focusing camera for exposing an image of an object on a film with a function of automatically focusing on the object. The camera includes a range-finding unit to measure the distance between the object and the camera, in which the range-finding unit is capable of measuring the distance with plural measuring areas; a circuit to calculate a moving speed of the object according the measured distance; a circuit to estimate a distance between the object and the camera when the camera exposes the image according to the measured distance by the range-finding unit and the calculated moving speed, before the camera exposes the image; a circuit to determine whether the moving speed exceeds a predetermined speed; and a controller to change the measuring area of the range-finding unit from one measuring area to the other area when the camera determines that the moving speed exceeds the predetermined speed.
