Abstract
A camera is provided with an automatic focus adjusting apparatus. The automatic focus adjusting apparatus includes a focus detecting device which detects the focus adjusted state of the photo-taking lens. A monitor device which monitors the movement of the photo-taking lens and an image plane movement speed calculating circuit which calculates an image plane movement speed on the basis of the result of the detection by the focus detecting device and the result of the monitoring by the monitor device. A moving object discrimination circuit discriminates an object as a moving object when the image plane movement speed is equal to or greater than a threshold value. A threshold value setting circuit sets the threshold value used for moving object discrimination in the moving object discriminating circuit. The threshold value setting circuit changes the threshold value when a continuous shooting device is driven.
