Abstract: A camera which has the capability of making exposures according to apertu distance, and exposure-time settings and which can also make flash exposures is provided with a housing which carries an adjustable structure movable with respect to the camera housing to provide one of the above settings, this adjustable structure also having a flash position at which it can be set with respect to the camera housing. An electronic flash device is capable of being removably connected with the camera housing by way of a connecting structure carried in part by the flash device and in part by the camera housing. This electronic flash device has a normally open switch which must be closed to render the electronic flash device operative. A switch-operating member is movably carried by the camera housing for movement with respect thereto between a rest position and a switch-closing position where the switch-operating member cooperates with the switch of the flash device to close the latter switch. The adjustable structure when displaced to its flash position engages the switch-operating member to displace the latter to its switch-closing position so as to render the flash device operative.

Abstract: An electronic flash accessory is provided for a camera of the type having a flash socket assembly adapted for receipt of a conventional multiple flash bulb array together with circuitry for sampling the terminals of the flash socket which are adapted to connect to the last flash bulb scheduled to be fired in the array and for providing a signal which operates to inhibit camera operation when the sampled impedance of the last flash bulb scheduled to be fired is substantially different from the impedance of an unfired non-defunct flash bulb. The electronic flash accessory includes circuitry responsive to a predetermined event relative to the readying of the flash accessory in expectation of the commencement of a photographic exposure cycle involving an artificially illuminated subject for simulating the impedance of an unfired non-defunct flash bulb in order to enable the camera to automatically perform a photographic exposure cycle upon actuation by the camera operator.

Abstract: An electronic flash unit having a foot which supports a depressible actuating lever for a grey filter which is moved by the lever in front of a photoelectric transducer in the casing of the flash unit when the foot is inserted into the shoe of a camera with a fixed diaphragm whose aperture is not suited for the making of exposures with flash but not when the foot is inserted into the shoe of a camera having an adjustable diaphragm capable of furnishing an f/stop which is suited for the making of exposures with flash without any adjustments of illuminating means in the casing of the flash unit. The placing of the filter in front of the transducer compensates for the fact that the aperture of the fixed diaphragm is unsatisfactory for the making of exposures with flash without any adjustments of illuminating means in the casing of the flash unit. The foot can be inserted into or withdrawn from a shoe by moving it in parallelism with or at right angles to the optical axis of the lens system in the respective camera.

Abstract: An adapter arrangement for use with a photographic flash firing circuit of a variety which monitors and senses the ignition of a flashlamp. Upon a successful such ignition, the firing circuit derives a unique output signal condition which is used for post exposure control purposes. The adapter arrangement permits such a circuit to be utilized for actuating an electronic flash unit or the like in place of typical flashlamps. To carry this out, an impedance having a resistance value closely related to that of an igniting flashlamp is incorporated in operational union with a switching arrangement. In one embodiment this impedance is combined with the winding of a relay. The relay serves to actuate the substitute lighting unit, while the resistive impedance serves to simulate the impedance of the igniting filament of a flashlamp. With the arrangement, therefore, the flash firing circuit is capable of developing a necessary unique output signal.

Abstract: The electronic device of the present disclosure has a mounting section, a voltage determiner, and an attach-detach detector. The mounting section accepts a removable, externally-connected device and connects to a data line into which a unit signal having a data period for transmitting a data signal and a detection period for transmitting a detection signal is fed from the externally-connected device. The voltage determiner determines an electric potential of the data line so as to have a first logical value when the externally-connected device is detached from the mounting section. The attach-detach detector detects whether the externally-connected device is mounted on, or detached from the mounting section by detecting the detection signal of the first logical value determined by the voltage determiner or a second logical value.

Abstract: The present invention relates to an underwater photographic lighting device which comprises: a flashlight body fully sealed by a seal, the interior of the flashlight body is provided with waterproof through holes, the flashlight body is respectively connected to a lamp head and a flashlight via conductive connecting cables, the lamp head is sealed by a seal, and connecting parts can be respectively dismounted from the flashlight body; and a power supply component sealed by a seal and connected to the flashlight body. Every part of the underwater photographic lighting device of the present invention is sealed, so the waterproof function is better; and each part is independent, and therefore can be optionally replaced and maintained. The battery module can be replaced and upgraded according to future need, and can be independently charged, so that the life cycle of the whole device is extended. When a beam head is used for photographing, a reflection cup and a condensing lens that are added on the beam head can increase light efficiency, so that a better photographing and recording effect can be achieved. In addition, since the device can be connected to a camera or a camcorder without a grip, a clamp or other parts, the device is convenient, light in weight and practical.

Abstract: An optical device includes a clamp seat and a light tuning assembly. The clamp seat includes a base, a curved potion extending from the base, and a pressing portion extending from the curved portion. The light tuning assembly includes a support frame disposed at the base, an optical lens restrained by the support frame, and an adjusting member coordinating with the optical lens. In an application of the optical device, a user may clamp a multimedia mobile communication device by the base and the pressing portion to allow the optical lens to align with a light projecting assembly of the multimedia mobile communication device. The adjusting member is rotated to adjust a distance between the optical lens and the light projecting assembly. Light from the light projecting assembly is then focused or dispersed through the optical lens to solve an issue of unadjustable light of a conventional solution.
