ABSTRACT:
An active range-finding device includes a light-projecting section for successively projecting range-finding light beams toward an object in a plurality of directions, a plurality of light-receiving sections for receiving light beams reflected from the object, a distance data calculating section for calculating a distance to the object on the basis of a plurality of outputs from the light-receiving sections, and a speed calculating section for calculating the movement speed of the object in two directions perpendicular to each other which include at least the direction of the optical axis of a photographing lens. The position of the photographing lens at the time of film exposure is corrected on the basis of the movement speed of the object output from the calculating section.
