摘要： An automatic focusing device for a camera is arranged to binary-code luminance levels obtained in a plurality of areas set on an image sensing plane; to detect any change in the binary coded inforamtion between timewise different fields; and to compute a degree and range of the change. An automatic focusing action is brought to a stop when the computed degree of change exceeds a predetermined value on the assumption that the change results from a movement of the camera due to camera shake or panning. In case that the degree of change is less than the predetermined value, the change is considered to have resulted from a movement of an object to be photographed. In that event, the focusing action is allowed to continue by tracing the moving object witha focus detecting zone.
