The image pickup lens 7 includes a multifocal lens on the lens surface of the first lens 1 facing the object side. D and Ymax satisfy the following conditional expression (1): 0≦D/Ymax≦0.1  (1) where D is an absolute value of the distance between the multifocal lens surface and a surface of the aperture stop on the optical axis, and Ymax is the absolute value of the maximum image height on an image plane formed on the image sensor.

    Abstract: In an electronic flash device of the type in which depending upon the exposure conditions an electronic flash lamp converts into light the energy stored on a main flash capacitor or the energies stored not only on the main flash capacitor but also on an auxiliary flash capacitor, a switching element which is turned on or off so as to permit or interrupt the discharge of the auxiliary flash capacitor is controlled by a simplified control circuit comprising a switching element control circuit which delivers a low voltage supplied from a low-voltage power source to the switching element as a turn-on signal and a detection circuit which controls the switching element control circuit in response to the exposure conditions such as a distance to a subject or a selected aperture. Therefore, an inversion circuit which is used in the prior art electronic flash devices can be eliminated.

    Abstract: In a motion verifying photography method, a latent image is captured during a film exposure time interval. The film exposure time interval has an initial portion, a middle portion, and a final portion. A first digital image is captured during the initial portion of the film exposure time interval. A second digital image is captured during the final portion of the film exposure time interval. A representation of both electronic images is visualized. A motion verifying camera has an exposure frame, an electronic array imager spaced from the exposure frame, an optical system directing light along a first path to the exposure frame and along a second path to the imager. Shutters are disposed on both paths. A shutter release connects to an actuator and responsive to the actuator, momentarily opens the film shutter for a film exposure time interval having an initial portion, a middle portion, and a final portion. The actuator momentarily opens the imager shutter during the initial portion and momentarily opens the imager shutter during the final portion.

    Abstract: An image-capturing device includes a detector which detects that a resistance value of an actuator, made of shape memory alloy, is maintained within a predetermined range. The image-capturing device moves a lens step by step from a place corresponding to a first field in order to obtain image data from each one of the fields provided in a focus region. The image-capturing device also calculates a target place, where the lens should be finally positioned, by using the obtained image data, and then positions the lens at the calculated target place. The foregoing structure allows obtaining reliable and stable data.
