A camera includes a movable cylinder movable relative to a stationary cylinder in an optical axis direction of a lens to function as a shutter, and a drive lever attached to the stationary cylinder to be rotatable about a lever shaft. The movable cylinder includes a shutter blade attached to a shutter base in a manner rotatable between a closing position to cover an exposure window in the shutter base and an opening position to uncover the exposure window, and a coil spring urging the shutter blade toward the closing position. The drive lever includes a drive engageable with a hook in the shutter blade in the movable cylinder. The camera includes a lever stopper that retains, against an urging force from a coil spring, the drive lever at a charge position at which the drive in the drive lever is engageable with the hook in the shutter blade.

A blade driving device is smaller and has fewer components. A blade driving device includes a base including a support shaft extending frontward, a cover having an opening, a blade located in a blade chamber defined between the base and the cover, and an actuator that moves the blade between a closing position to cover the opening and an opening position to uncover the opening. The cover covers a front of the base. The actuator includes a lever connected to the blade. The lever includes a lever body rotatable about the support shaft in the base, a connector connecting the lever body and the blade, and a protrusion protruding from the lever body frontward beyond the blade and facing the cover.

An imaging system includes a stationary imager. An opaque enclosure includes a plurality of apertures at different locations on the enclosure and a plurality of stationary beam splitters arranged within the enclosure such that light that enters the enclosure through each of the apertures is directed to the imager. A shutter unit includes an opaque surface that includes at least one window. The shutter unit is rotatable relative to the enclosure such the window is sequentially aligned with each of the apertures to enable light from a field of view to enter the enclosure through that aperture, the opaque surface preventing light from concurrently entering the enclosure through more than one of the apertures.

An optical member driving mechanism is provided, including a fixed portion, a movable portion, and a driving module, wherein the movable portion is movably connected to the fixed portion and includes an optical member holder and a spacing member. The optical member holder can support an optical member and has a surface facing the optical member. The optical member can change the moving direction of an external light. The spacing member is disposed between the surface and the optical member, and a gap is formed between the surface and the optical member. The driving module can drive the movable portion to move relative to the fixed portion.

An optical system is provided, including a holder, a fixed module, a driving assembly, and a first resilient member. The holder is used for holding an optical element that defines an optical axis. The fixed module is movably connected to the holder and has a housing and a base connected to the housing. The base has a bottom surface parallel to the optical axis and a first pillar forming a first surface that is not parallel to the optical axis. The driving assembly drives the holder to move relative to the fixed module. The first resilient member is disposed on the first surface and movably connects the holder with the fixed module.

An optical element driving mechanism is provided, including a movable part, a fixed part, and a driving assembly. The movable part is used for connecting an optical element. The movable part is movable relative to the fixed part. The driving assembly is used for driving the movable part to move relative to the fixed part. The driving assembly is used for driving the movable part to move in a first dimension.

A driving mechanism is provided, including a fixed part, a movable assembly, an optical assembly, and a driving assembly. The movable assembly movably connects the fixed part with the optical assembly. The driving assembly is configured to drive the movable assembly and the optical assembly to move relative to the fixed part.
