Embodiments of the present disclosure include an apparatus with a camera. A shutter is positioned horizontally in front of the lens of the camera. The shutter is configured to move in front of a lens of the camera and is further configured to move orthogonally to the horizontal axis so as to at least partially obscure the lens of first camera in a closed shutter position. The apparatus further includes a motor positioned horizontally behind the front of the lens of the camera. The motor is configured to move the shutter orthogonally to the horizontal axis between the closed shutter position and an open shutter position.

A camera system that includes a camera having a main body having a front surface and a back surface; a lens disposed within the main body and configured to view objects in front of the front surface; a magnet coupled to the back surface, wherein the magnet is configured to removably couple the camera to a ferromagnetic material; a shutter adjustably coupled to the main body, so that the shutter is moveable relative to the lens between a closed position and an open position; and a controller disposed within the main body and configured to control operation of the camera.

The imaging device comprises: an imaging unit, a shooting processor, an exposure information setter, and an image processor. The imaging unit stores electric charges in response to an incident light for each frame, thereby outputting an image signal. The shooting processor controls storage times, during which the imaging unit stores the electric charges. The exposure information setter sets first exposure control information that controls brightness of a first image signal generated based on a first storage time and second exposure control information that controls brightness of a second image signal generated based on a second storage time. The image processor combines the first and the second image signal. In the case where the first exposure control information satisfies a given condition, the exposure information setter sets the first and the second exposure control information such that storage times corresponding to frames adjacent to each other become equal to each other.

A light shielding blade including a laminate in which a resin layer is sandwiched between two metal base materials, wherein the two metal base materials each have a specific rigidity of 20×10.sup.6 [Pa.Math.m.sup.3/kg] or more and a specific bending rigidity of 1.0 [Pa.sup.1/3.Math.m.sup.3/kg] or more, and wherein the resin layer has an elastic modulus of 1 GPa or more and a thickness of 65 μm or less.

A self-damping shutter apparatus for use in an exposure system of a photolithography machine, comprising: at least two pieces of shutter blades (1) for cutting off light source to an exposure area when the shutter is closed; a shutter driving arm (2), for driving the shutter blades (1) to synchronically open or close; a magnetic damping brake motor (3), for driving or braking the shutter driving arm (2), and the magnetic damping brake motor (3) drives and brakes, via the shutter driving arm (2), the shutter blades (1). The self-damping shutter apparatus for use in the exposure system of the photolithography machine increases consistency of opening or closing the shutter blades, improves a light shading effect of the shutter apparatus in an exposure, and improves stability in the process of opening or closuring the shutter blades. When the shutter blades complete actions of opening or closing, current is not needed, the magnetic damping braking motor enables the shutter blades to maintain the state of opening or closing, shortens duration of control current, reduces heat dissipation, and saves energy.

A driving apparatus which is capable of smoothly moving a follower by a cam portion, and realizes the stopper structure of the follower by a small number of components without the size increased. The driving apparatus comprises an up cam gear having an up radial cam and an up thrust cam, and a down cam gear unit having a down radial cam and a down thrust cam. The up cam gear and the down cam gear unit mesh with each other in a vicinity of a region in which a lift amount of the up radial cam with respect to the follower increases. In a vicinity of a position at which the up cam gear and the down cam gear unit mesh with each other, a lift amount of the up thrust cam is larger than a lift amount of the down thrust cam in the thrust direction.
