ABSTRACT:
A distance measuring device for a camera has a near infrared light-projecting element for projecting measuring light to be reflected by an object to be photographed. The reflected measuring light is received as a first light beam image at a first position on a surface of a first light-receiving element. The reflected measuring light reflected by the object is also received as a second light beam image at a second position on a surface of a second light-receiving element. A CPU controls the focusing movement of the lens of the camera by computing a distance to the object depending on the first position, compensating the computed distance depending on the second position, and controlling the focusing movement of the lens based on the compensated computed distance. The CPU compares the second position with a predetermined distance value and inhibits the compensation of the computed distance if it is determined that compensation is not necessary.
