In a distance measuring system in a camera including an integrating unit having an integrating capacitor, if the period of a second integration exceeds a maximum period, a CPU stops the second integration. Furthermore, the CPU informs a photographer that the distance measurement has not performed successfully by issuing an alarm, urging the photographer to take proper action. As the CPU determines the distance to the object to be measured based on the maximum period of the second integration, error in the distance measurement may be minimized.
