A camera is configured for use with a removable camera lens cover, which can be secured to or removed from the camera by a user without the use of a tool set. The mechanism which allows the lens cover to be secured to and removed from the camera includes a set of wires embedded into the lens cover and a set of wedges protruding from the lens wall of the camera. To secure the lens cover to the camera, the lens cover is placed onto the front of the camera and rotated until the wires align with corresponding wedges, securing the wires underneath the tapered surface of the wedges. To remove the lens cover from the camera, a force is applied outward and normal to the lens cover, causing the wires to flex outward and enabling the rotation and removal of the lens cover from the camera.

Various embodiments described herein relates to a lens cap, adapted to be mechanically engaged over a lens assembly of an optical projector. The lens cap, as described herein, is adapted for vignetting a light pattern projected by the optical projector. The lens cap includes a front surface and a back surface, where on at least a portion of the front surface, an elliptically shaped aperture is defined. In this aspect, the elliptically shaped aperture is chamfered towards its peripheral ends, as the elliptically shaped aperture extends out from the back surface of the lens cap towards the front surface of lens cap. Also, the elliptically shaped aperture is defined on the lens cap such that, a center axis of the aperture is offset to a central axis of the lens cap, so as to match an offset at which the light pattern is projected by the optical projector.

A cover device is configured to be secured to an electronic device to obstruct the camera lens of a digital camera of the electronic device. The cover device may have a movable cover tab configured to be rotated and/or slid over the camera lens and rotated and/or slid off of the camera lens. The cover device may have adhesive such as pressure sensitive and/or electrostatic adhesive by which the cover device is secured to the electronic device.

An optical module for a vehicle includes an imager configured to collect image data from at least one of inside and outside the vehicle. A cover is disposed proximate a lens of the imager. The cover includes an electro-optic cell aligned with the lens and configured to allow the imager to capture the image data through the cover. The cover is colored to match one of an interior and exterior body panel of the vehicle. The electro-optic cell is operable between a first condition wherein the electro-optic cell has a visible light transmission of greater than 50% and a second condition wherein the visible light transmission of the electro-optic cell is less than 15%.

A mobile device case has a first lens cover and a second lens cover. The first lens cover and second lens cover are each moveable between a first position and a second position. A coupling connects the first lens cover to the second lens cover. When the first lens cover is in the first position and the second lens cover is in the first position, movement of the first lens cover from the first position to the second position, simultaneously and automatically moves the second lens cover from the first position to the second position. When the first lens cover is in the second position and unlocked, and the second lens cover is in the second position, a biasing force automatically moves the first lens cover into the first position from the second position, and the second lens cover, by way of the coupling, automatically and simultaneously moves into the first position. The first lens cover automatically locks in place by a locking construction when the first lens cover is moved into the second position from the first position.

Various methods, systems, and devices are described for iteratively masking and exposing integrated onboard cameras on electronic devices including laptops, tablets, and mobile phones. A User, such as an employee, an affiliated member of an organization, or independent consumer may leverage this integrated onboard camera masking solution to create privacy and/or exposure for the intended use of the camera at their direct specification. The User can change the configuration using their fingertip numerous times. The User can display this camera masking solution proudly with an identifiable message or graphic symbol that they feel represents themthus giving the User the ability to express themselves openly to other individuals. The camera masking solution also enables worry-free usage as it will not detach, break apart, or change configurations spontaneously based on basic User movements with the device. The solution will also not hinder the use of or damage the electronic device during its normal usage because it has a small footprint and it near paper thin in its construction.

A system includes a visual sensor provided in an industrial machine or in the vicinity thereof to acquire a plurality of image data, a calculation unit that calculates a contamination degree of a lens or a lens cover of the visual sensor on the basis of the image data acquired by the visual sensor, and a prediction unit that calculates information on a predicted cleaning timing to be performed in the future, of the lens or the lens cover on the basis of the calculated contamination degree of the lens or the lens cover.

A privacy shutter selectively covers and exposes a camera lens on a computer device. The privacy shutter has a frame with an aperture and a slider carried by the frame and slidable in the aperture. The slider slides between open and closed positions. The frame has a channel in an outer side of the frame and extending from the aperture to a perimeter of the frame. The channel has an outer opening and an inner cavity slidably receiving the slider therein. The outer opening of the channel exposes the outer surface of the slider in both the closed and opened positions.

A lens screening device includes a hollow housing, the top and bottom surfaces of which respectively have a corresponding through hole; the housing defines an accommodation space, inside which a shaft is configured, and the shaft is configured with a magnetic element, the top surface of which is in combination with a plate body, another end of which is positioned between the through holes; the two ends of the magnetic element respectively are a positive pole and negative pole; the two sides of the magnetic element are respectively configured with an iron core, the bottoms of the two iron cores are in connection with each other, the two iron cores are respectively configured with a first coil and second coil respectively in connection with a positive lead and negative lead; the first coil is adjacent to the positive pole, and the second coil the negative pole.
