The switching circuit is used to change the destination of outputs of the sensor arrays to an A/D conversion circuit, whereby range finding is carried out in a passive AF mode. Moreover, the switching circuit is used to change the destination of outputs of one sensor array to the AF IC, whereby range finding is carried out in an active AF mode. According to the present invention, a compact and inexpensive camera having the ability to carry out range finding in two modes and capable of properly measuring a distance to any of objects lying in a wide area can be realized.

    • A distance-measuring device of this invention is characterized in that the distance measured by the PSDs is corrected on the basis of the direction and the amount of a spot light deviation obtained by a combination of three light-receiving elements that receives an asymmetrical spot, in order to prevent erroneous distance measuring due to spot light deviations in an infrared projection trigonometrical measurement system. With the present invention, the IRED projects a spot with protruding portions symmetrical and perpendicular to the base length, onto the subject. Then, the SPD of a first light-receiving section of a light-receiving element located the base length away from the IRED receives the protruding portions of the spot, and the SPD of a second light-receiving section receives the protruding portions. This allows the incident position of the reflected light from the object to be sensed. Based on the output of the SPDs of the light-receiving element, the AFIC computes the distance to the object.

    • A distance measurement apparatus for use in a camera having a CPU. The apparatus has no analog distance-measuring IC and can yet perform active distance measuring. It comprises an infrared-emitting diode (IRED), a light-receiving element and an integration circuit, both connected to the ports of the CPU. In operation, the IRED emits an infrared beam toward an object. The light-receiving element receives the beam reflected form the object and stationary light and converts the beam and the light into an electric signal. The integration circuit integrates the electric signal. The CPU measures a first period of time lapsing from the time when the the integration circuit is initialized to the time when the output of the integration circuit increases over a predetermined value. The CPU also measures a second period of time lapsing from the time when the the integration circuit is initialized to the time when the output of the integration circuit increases over the predetermined value while the IRED is emitting no infrared beam. From the first and second periods of time, thus measured, the CPU determines the distance at which the object is located, not influenced by from the stationary light at all.
