摘要:
A digital camera comprises two photographing systems which are independent of and substantially identical to each other, and each of which includes a photographing optical system and an image pickup device. The photographing optical system is configured to include a photographing lens, a focusing lens and an aperture stop. The focusing lens of one of the photographing systems is driven stepwise from a first predetermined position at which it is to be located when a focusing position lies at an infinite distance, toward a second predetermined position at which it is to be located when the focusing position lies at the closest distance, while the focusing lens of the other photographing system is driven stepwise from the second predetermined position toward the first predetermined position every step width. The contrasts of images formed by the respective photographing systems are evaluated while the two focusing lenses are being moved, and a position corresponding to the maximum value of the contrasts is determined as the focusing position.
摘要:
A switching power source which enables a continuous operation of an apparatus even under an overvoltage test such as a ring wave test. In a case where the sensed voltage (Vb) of the secondary winding (5b) through a diode (D6), the Zener diode (ZD3), and a resistor (R21) to the non-inverting input terminal (+) of a comparator (31), and a high-level signal is inputted to a flip-flop (35) from the comparator (31). As a result, a high-level signal outputted from the Q output terminal is held and outputted to a flip-flop (15) as a reset signal via an OR circuit (37), so that a drive signal kept outputted from the Q output terminal of the flip-flop (15) switches to a low-level one to continue the off-control of the switching element (Q1).
摘要:
A d.c.-to-d.c. converter of the kind having a step-up or step-down transformer with a primary to be connected to a d.c. power supply via an electronic switch, and a secondary to be connected to a load via a smoothing and rectifying circuit. The voltage being applied to the load is detected and fed back to a switch control circuit whereby the switch is controlled to keep constant the converter output voltage. Connected in parallel with the transformer primary, a surge suppressor circuit has a serial connection of a surge-absorbing capacitor and a rectifying diode and a resistor for absorbing a surge developing across the transformer primary winding each time the switch is turned off. In order to attenuate the high-frequency ringing of the voltage across the switch due to the leakage inductance and stray capacitance of the transformer primary and to the stray capacitance of the switch, the reverse recovery time of the diode of the surge suppressor circuit is made longer than half the cycle of the ringing voltage and shorter than the expected minimum non-conducting period of the switch.
摘要:
An imaging device including an image pickup device which converts an optical image of a photographic subject received through an imaging lens into an image signal; a displaying device which displays a through-the-lens image based on the image signal; a person detecting device which detects one or more persons from the image signal; a distance calculating device which calculates a distance between a plurality of the detected persons; and a composition assisting device which displays on the displaying device information as to whether the distance between the detected persons is proper or not based on the calculated distance between the detected persons. Thereby, it is possible to obtain an image with a proper composition in a case when there are a plurality of persons being the photographic subjects.
