The camera view-correction apparatus comprises at least one dividing plate located in the view finder so as to divide the view finder into several regions. Each region has a light source at the far end, so that when all the light sources are successfully observed without being shielded by the dividing plate, it indicates that the optical axis of the view finder is matched with the optical axis of the lens. Alternatively, the camera view-correction apparatus has a plurality of plates located in the view finder. The plates enclose a tunnel free space with a cross shape for the cross-sectional view. Light can pass the tunnel free space and reach the eyes. If the optical axis of the view finder is tilted, some portion of the light is shielded by the plates with respect to the tilted direction.

A hidden viewfinder for camera includes a camera body having a pair of spaced channel slots, a plurality of lens frames each having a bottom end pivotally hinged on the camera body between the channel slots and a reversed U-shaped tunnel type outer frame having a top wall and two side walls engageable with the channel slots. There is a torsional spring engaged with the bottom end of each lens frame. When the outer frame is pressed down and held in the channel slots, the top wall will press the lens frames to turn about the bottom ends for the lens frames laying horizontally on the camera body to form a compact size camera. When in use, the outer frame is raised above the camera body, the torsional springs will raise the lens frames upright to form the viewfinder in the outer frame. Circuit boards and control elements may be placed in the camera body between the channel slots for the camera because compact size but rich in function.

A device for controlling a rotation of a lens in a digital camera includes a lens connected to and exposed out of the housing of a digital camera and a motor disposed within the housing of the digital camera. The lens is provided with a shaft which extends through the housing to have an end extending into the interior of the housing which is disposed with a follower gear. The motor has a drive spindle which is disposed with a driving gear. A set of reduction gears are disposed between and engageable with the follower gear on the shaft of the lens and the driving gear on the drive spindle of the motor. By means of the rotation of the motor, the lens is rotatable horizontally, while the digital camera remains stationary, to a desired direction in order to take a picture.

A lens-aperture control mechanism is provided for use in a lens unit to control the aperture of the lens unit. The lens-aperture control mechanism includes a plurality of blades, each being movable radially inward into the lens barrel and outward from the lens barrel; a rotatable ring coupled to the blades, capable of urging the blades to move radially inward into the lens barrel when being turned in a first direction and outward from the lens barrel when being turned in a second direction; and a power driver for driving the rotatable ring to turn in a specified direction by a specified angular displacement so as to move the blades to a specific radial position to define a specific aperture for the lens unit. The inner end of each of the blades is formed in a concave shape or a curved haft-cutaway portion. When combined, the inner ends of the blades can define a near-circular aperture for the lens unit. This lens-aperture control mechanism can variably control the lens aperture to the desired value and can provide a near-circular aperture for the lens. Moreover, the lens-aperture control mechanism, being simple in mechanical construction, is easy to assemble and thus low in manufacture cost.

An aperture switching device to be incorporated in a digital cameral for moving an aperture plate having an aperture formed thereon with respect to a lens between a shutting position where the lens is partially covered by the aperture plate with the aperture aligned with the lens and an open position where the lens is not covered by the aperture plate, includes a slide block formed on the aperture plate, a guide member mounted to the lens and having a guide channel to slidably receive the slide block therein. A driving device has an output rod movable along an arc path and mechanically coupled to the aperture plate to reciprocate the slide block along the guide channel so as to move the aperture plate between the shutting position and the open position. The mechanical coupling between the driving device and the aperture plate may include a pinion rotated by the driving device and engaged by a rack provided on the aperture plate. Alternatively, the mechanical coupling may include a transverse channel formed on the aperture plate to receive the output rod of the driving device therein. The transverse channel extends in a direction substantially normal to the movement of the aperture plate so as to convert the arcuated movement of the rod into linear motion of the aperture plate.

An aperture selection mechanism for camera lens includes an aperture strip and a disk selection knob. The aperture strip has two or more different sizes of apertures equally spaced from each other and being sequenced by size. Turning the selection knob, the aperture strip will be moved and one of the apertures will be positioned in the light path of the camera lens. Two or more apertures may be moved to the light path of camera lens one at a time so that the camera can produce better quality of photo and image. The structure is simple, low cost and easy to use.

A lens movement mechanism for digital camera includes a lens set which has a composite lens and a Charged Couple Device built therein, a first movement member for turning the lens set angularly left or right, and a second movement member for turning the lens set angularly up or down. The first movement member includes a bracket piovtly holding the lens set and a gear set for turning the bracket and the lens set left or right angularly. The second movement member includes a slant block with a slope surface contact with a rear end of the lens set so that when the slant block is moved transversely, the lens set will be tilted up or down angularly. Therefore the lens set may be turned left or right, up or down smoothly and precisely without a user's hand moving the lens set directly. The lens may be prevented from hand smearing. Higher photo quality may be achieved.

An opto-mechanical apparatus for moving and scanning in an optical system comprises a step motor, a timing belt, a first lead screw carrying a first optical assembly, and a second lead screw carrying a second optical assembly. Each of the lead screws has a spiral thread forming a lead path. The lead path of the second lead screw is twice as long as the lead path of the first lead screw. Each lead screw has a gear fastened to its one end. The timing belt connects the rotation axis of the step motor and the two gears on the lead screws. When the step motor rotates, the two gears are driven by the timing belt. The two lead screws are also rotated by the gears. The first optical assembly moves twice as fast as the second optical assembly because the two gears have identical radii but the second lead path is twice long. The different distances traveled by the two optical assemblies ensure that the optical system has a constant optical resolution while scanning.
