An example shutter assembly for protecting cameras, such as webcams, integrated into computing devices is disclosed. The shutter assembly includes an actuator element and shutter element. The actuator element can rotate an axis to pivot the shutter element into and out of the field of view of the camera assembly. The actuator can extend through or be otherwise accessible through the housing of the computing device so that the shutter can move in a plane parallel to the front surface or bezel of the computing device. Because the shutter element operated from a surface other than the front facing surface, the bezel can include a single surface with a window to protect the camera assembly and allow for a touch control capabilities. The shutter element can be disposed between the bezel and the camera assembly to provide privacy from the camera being inadvertently or maliciously activated.

To enable continuous operational control of the blade member with high resolution and good accuracy, even when achieving miniaturization and thickness reduction in a blade driving device, through enabling smooth movement of a movable member in a blade driving device. A blade driving device 1 comprises: a base member 2 that has an opening 2A; one or a plurality of blade members 3 that operate so as to advance into the opening 2A or withdraw from the opening 2A; a driving member 4 that moves within a plane that is perpendicular to the optical axis that passes through the opening 2A, to drive the blade member 3; and supporting members 7 that are provided between the base member 2 and the driving member 4, so as to provide sliding support or elastic support of the driving member 4 in a state that is separated from the base member 2.

An information handling system peripheral camera ensures privacy with a cover that minimizes distance of a camera module to a front opening of the camera housing. For instance, opposing cover members rotate about geared ends that engage to translate rotation between the members, where the members meet over a camera opening to block capture of visual images and move to opposing sides to expose the camera module. In an alternative embodiment, a rotating shutter arrangement selectively covers the camera for security and also covers a microphone to provide security against unauthorized audible access through the camera. Selective covering and exposing of a camera module, infrared camera, microphone and user presence detection sensor support adaptive security at a camera based upon end user context.

An optical system is provided. The optical system includes a first optical module with a first light-entering hole, a second optical module with a second light-entering hole, and a third optical module with a third light-entering hole. The second light-entering hole is close to the first light-entering hole and the third light-entering hole. The focal length of the second optical module is different from the focal length of the first optical module and the focal length of the third optical module.

An optical element driving mechanism includes a fixed portion, a movable portion, a driving assembly, and a limiting assembly. The movable portion is connected to an optical element with an optical axis, and is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The limiting assembly is disposed on the movable portion and is connected with the driving assembly. The driving assembly is limited to move within a movable range relative to the fixed portion by the limiting assembly.

An effect that drive of one of a first magnetic driving unit and a second magnetic driving unit prevents a movement of the other magnetic driving unit is not generated to appropriately control movements of first opening and closing blades and second opening and closing blades. A blade opening and closing device includes a base body which includes an opening for transmitting light, a first magnetic driving unit which includes a first magnet and a first coil, a second magnetic driving unit which includes a second magnet and a second coil, first opening and closing blades which are moved by the first magnetic driving unit relative to the base body and to open and close the opening, and second opening and closing blades which are moved by the second magnetic driving unit relative to the base body and to open and close the opening. A magnetic flux direction of the first magnetic driving unit is opposite to a magnetic flux direction of the second magnetic driving unit.
