Abstract: An analog-to-digital converter that converts an inputted analog signal into a digital value is disclosed that may include unit circuits that each generate reference voltages comprising regular potential intervals by a series resistor circuit connected between a high potential side reference voltage and a low potential side reference voltage and convert the reference voltages into a digital value by comparing the reference voltages with the inputted analog signal, and an adder that adds the digital values converted by the unit circuits. Each unit circuit may include coupling switches that couple the series resistor circuit with the series resistor circuit of another one of the unit circuits and connect the series resistor circuits between the high potential side reference voltage and the low potential side reference voltage and a sharing switch that shares the inputted analog signal with the other unit circuit that is coupled with the series resistor circuit.

Abstract: The present invention relates to a camera module having an auto focus function, the module including a lens unit having at least one lens, a barrel into which the lens unit is inserted, and connected by a VCM (Voice Coil Motor) actuator, and an image sensor discretely positioned from the lens unit to convert light having passed the lens unit to an electrical signal, where the VCM actuator includes a gap of a reference distance position value which is a position of an object catering to a lens focal length according to the camera module, and information on a focus-met lens position value, and adjusts an initial position of the lens by using the gap of reference distance position value of the lens position value during operation of the camera module.

Abstract: A mobile electronic device is provided which includes a housing and a button arranged in an outer surface of the housing. Adjacent to the button, a surrounding member is provided. The surrounding member is movable with respect to the housing.

Abstract: A shutter control apparatus and the method thereof are provided. The shutter control apparatus is suitable for controlling a shutter of a camera apparatus. The shutter control apparatus includes a resistor and a switch. The resistor is coupled between an output terminal and a ground voltage source. The switch is coupled between a voltage source and the output terminal. The switch has a first trigger and a second trigger. The shutter of the camera apparatus is turned on/off by the shutter control apparatus according to the timing between the first trigger and the second trigger of the switch. Thereby, the shutter control apparatus has less component and compactness.

Abstract: After loading a film cassette into a cassette chamber, a lid of the cassette chamber is closed. Interlocking with the lid, a lid lock member is moved to a lock position to lock the lid. When the lid lock member is moved to the lock position, a shutter lock member allows to operate a shutter release button. When the shutter release button is operated, a shutter is driven and a photo film is advanced. When the lid lock member is moved to an unlock position, the lid is opened. When the cassette chamber is opened, the shutter lock member prevents the operation of the shutter release button to prohibit the advancing of the photo film.

Abstract: A camera comprising an aperture through which ambient light is passed to cause a film exposure, a shutter blade movable open to uncover the aperture and movable closed to re-cover the aperture and susceptible of being moved accidentally due to mechanical shock such as when the camera is dropped or jarred, and a shutter release button manually depressible for the shutter blade to be moved open to uncover the aperture, is characterized in that a blocking device is positioned adjacent or adjoining the shutter blade to prevent the shutter blade from being moved open to uncover the aperture due to mechanical shock, and is movable away from the shutter blade to permit the shutter blade to be moved open to uncover the aperture, and the shutter release button is connected with a driver that moves the blocking device away from the shutter blade to permit the shutter blade to be moved open to uncover the aperture only when the shutter release button is manually depressed.

Abstract: A shutter mechanism comprising an aperture through which ambient light is passed to cause a film exposure, a pair of shutter blades supported for pivotal opening movement in opposite opening directions away from one another to uncover the aperture to permit ambient light to pass through the aperture and for pivotal closing movement in return closing directions towards one another to re-cover the aperture and supported to allow them to be pivoted simultaneously in the same direction to cause accidental shutter opening when a physical shock is applied to the shutter blades in the opening direction of one of the shutter blades, is characterized in that each one of the shutter blades completely covers the aperture in order that both of the shutter blades must be removed from the aperture to uncover the aperture to permit ambient light to pass through the aperture, and a single fixed stop is positioned between the shutter blades to prevent either one of the shutter blades from pivoting in the same direction as the

Abstract: An improved camera comprising a strobe circuit, a strobe, a shutter mechanism and an actuating mechanism are disclosed. A finger engageable portion of the shutter mechanism operates the shutter. A shield is movable between a first blocking position for blocking the finger portion against engagement to prevent accidental actuation of the shutter mechanism, and a second position exposing the finger portion for engagement to actuate the shutter. An assembly operatively interconnecting the shield and the strobe circuit to energize the strobe circuit when the shield is in the second position.

Abstract: A camera having a body, a push-pull, a sliding member, a shutter release, and a timer. The push-pull is movable between primary and secondary positions. The sliding member has a shutter button arm, a shutter actuation arm, and a timer release arm. The sliding member is moveable from a first to a second position by depression of the shutter button arm. The sliding member is limited to movement from the first position to an offset position when the push-pull is moved from the primary to the secondary position. The sliding member in the offset position is substantially blocked from moving toward the second position. The shutter release is movable from an initial position to a stopped position and to a released position. The shutter release is detained in the initial position by the shutter actuation arm when the sliding member is in one of the first and offset positions. The shutter release is released from the shutter actuation arm when the sliding member is in the second position.

Abstract: A photographic camera has a cartridge chamber in which is loaded a film cartridge having a roll film entirely rolled to its leading end around a spool in a cartridge body and a light-shielding shutter member for opening and shutting a film exit slit formed in the cartridge body, an entrance opening to the cartridge chamber, and a chamber lid which is mounted on the camera to be moved between an opening position where it opens the entrance opening and a closed position where it closes the entrance opening. A shutter lock member moves to a shutter locking position, where it prevents release of the shutter of the camera, in response to operation of a rewind button. A holding member holds the shutter lock member in the shutter locking position, and a release member causes the holding member to release the shutter lock member after closure of the light-shielding shutter member of the film cartridge in response to opening of the chamber lid.

Abstract: A camera with a lens barrier is provided with a slide member, which moves together with the lens barrier over a certain range of motion. A locking portion for keeping a shutter button locked and a stopper for limiting the push-down movement amount of the shutter button are integrated in the slide member. When the lens barrier is positioned at a position other than an opening position, the locking portion prevents the shutter button from being pushed down. When the lens barrier is positioned at the opening position, the locking portion moves away from the shutter button so that the shutter button can be pushed down, and the stopper limits the push-down movement amount of the shutter button. Thus, the locking portion for keeping the shutter button locked and the stopper for limiting the push-down movement amount of the shutter button are integrated so that the number of parts can be decreased to simplify the structure and lower the production cost.
