    摘要: To prevent temporary reduction of battery voltage when driving a shutter, an exposure control drive apparatus is provided with a boosting circuit for boosting a voltage of the battery and outputting a boosted voltage. A capacitor is charged by the boosted voltage for driving an actuator of an exposure control mechanism. A detecting circuit detects a current flowing in the boosting circuit and a control circuit controls operation of the boosting circuit in accordance with a magnitude of the detected value so that the boosting circuit is prevented from boosting the battery voltage when the detected current exceeds a predetermined level and is permitted to boost the battery voltage when the detected current is below the predetermined level. In this manner, the current flowing from the battery is prevented from exceeding a maximum level.

    摘要: A circuit for detecting back light comprises a time constant circuit including a capacitor selectively connectable in series with either a resistive element, or one of two CdS photoconductive elements used to measure the central and surrounding portions, respectively, of an object being photographed. Three switches separately conect the resistive element and the two photoconductive elements in series with the capacitor. A circuit generates pulses for a length of time governed by a time constant determined by the time constant circuit, and three separate counters store the pulses the number of which is determined by the time constant. An arithmetic circuit processes the pulses stored in the counters to determine the amount of back light present on the object.

    摘要: A device for detecting coincident focusing points for use in the controlling of the focusing of an automatically focusable lens comprises a single array of light receiving transducers for converting the distribution of light intensity of an image applied thereon to a set of corresponding electrical signals. The image applied to the array is from a first optical path from an object through the lens and from a second optical path from the object. At least one shutter is provided for cutting off one of the optical paths to alternatively effect the application of light from the one optical path on to the array to produce a first set of signals and thereafter the light from either the other optical path or the sum of the two optical paths on to the array to produce a second set of signals. The first set of signals are processed to produce a third set of signals which correspond to the ratio of each signal therein with respect to another of the signals and the second set of signals is processed to obtain a fourth set of signals corresponding to the ratio of each signal with respect to another of the signals. The third and fourth sets of signals, for each transducer, are compared and a signal is produced when a favorable comparison is obtained.

    摘要: In order to reduce noise in a controlling circuit including digital circuitry and analog circuitry constructed together on a single CMOS integrated circuit, a regulator is constructed as part of the integrated circuit. A power supply is directly connected to the digital circuitry, and a voltage output of the regulator is supplied to the analog circuitry. The output state of the regulator may be controlled by a switch. Degradation of the performance characteristics of the analog circuitry while the digital circuitry is being operated can be prevented by electrically isolating the power supply to the digital circuitry from the power supply to the analog circuitry. Since the regulator is built into the integrated circuit, the number of externally provided components is thereby reduced, further contributing to the downsizing of an electronic device such as a camera. Furthermore, even when the power supply of the digital circuitry fluctuates greatly, the effects on the analog circuitry are minimized.

A first memory stores output signals of the first and second signal processing circuits, the output signals being generated upon operation of the light projecting device when the first selecting device selects the first output signal and the second selecting device selects the second output signal. A second memory stores output signals of the first and second signal processing circuits, the output signals being generated upon operation of the light projecting device when the first and the second selecting devices both select the first output signal.
