A camera with a distance measuring apparatus has distance measuring functions by means of an active system and a passive system to allow good distance measurement with respect to an object in a wide variety of conditions. The camera includes a first signal forming unit, a second signal forming unit, a release detecting unit, an object condition detecting unit and a selective control unit. The first signal forming unit projects light distance measurement light from a light projecting unit, receives a reflection signal of the distance measurement light from the object at a light receiving unit and forms a focusing signal for the object. The second signal forming unit monitors the luminance distribution state of the object using an image signal detecting unit and forms a focusing signal for the object. The release detecting unit detects whether or not a release operating member is operated. The object condition detecting unit detects an object condition based on a signal obtained by actuating either the first signal forming unit or the second signal forming unit before the operation of the release operating member. The selective control unit selectively controls either the first signal forming unit or the second signal forming unit based on the detection result of the object condition detecting unit if the release detecting unit detects the operation of the release operating member.

[ What is claimed is:] [1.]1. A camera with a distance measuring apparatus comprising:light projecting means for projecting signal light onto an object;first signal means, having light receiving means for receiving a reflection signal of the signal light from the object, for forming a first signal used for measuring a distance to the object;second signal means, having image signal detecting means for detecting an image signal of the object, for forming a second signal used for measuring the distance to the object;photographing start detecting means for detecting operation of a photographing start operating means for operating the camera when a photographer is to take a photograph;actuating means for setting the camera in an operating state; andcontrol means for obtaining one of the first and second signals used for measuring the distance to the object by actuating one of the first and second signal means before the photographing start detecting means detects operation of the photographing start operating means and after actuating the actuating means, and for determining a priority as to actuating one of the first and second signal means at a timing after the photographing start detecting means detects the operation of the photographing start operating member based on the obtained signal.
