Abstract: PROBLEM TO BE SOLVED: To prevent distance measuring errors from occurring due to a dielectric absorbing phenomenon of an integrating capacitor by giving a direction for distance measuring operation before the actual operation beings to electrically charge the integrating capacitor of a double integration means. SOLUTION: When a main switch 7 of a camera has been changed over and a shift to a standby position for photographing has been detected, a CPU 6 starts the operation of measuring a distance and an integrating capacitor in a double integration circuit 5 beings to be charged. Hence, the charging of the integrating capacitor is accomplished during a series of distance measuring operations. Then, in the photographing operations, that is, when a first stroke switch 8 of the camera is turned on and a distance measuring start signal is outputted form the CPU 6, the charging of the integrating capacitor in the double integration circuit 5 is started.
