Abstract: A lens cover selectively covers and exposes a, camera lens on the back of mobile device, such as a cellular phone. The lens cover can be adhered to the back of the mobile device. The lens cover has a flap that pivots 180 degrees about an axis parallel with the back of the mobile device, and between an open/storage position and a closed position. The flap can be off-set with respect to the axle so that in the open/storage position, the flap is adjacent or abutting to the back of the mobile device, and so that in the closed position, the flap is spaced-apart from the back of the mobile device, creating a gap to receive a protruding camera or camera lens. The flap can also comprise a detent to maintain the flap in a selected position until selectively moved.

Abstract: A photo shooting support device or selfie device, includes a telescopic stick and a clamping device for holding and clamping a camera device. The clamping device includes a carrier and a stretchable clamping mechanism arranged above the carrier. The clamping device is pivotally or rotatably connected to the top end of the telescopic stick. A notch is arranged on the carrier. The middle portion of the clamping mechanism is provided with a bending portion corresponding to the notch. The telescopic stick can be accommodated in the notch and the bending portion after folding. The clamping device is always rotatably connected to the top end of the telescopic stick; so it does not require temporary assembly for use, bringing great convenience to users; and after use, the telescopic stick can be directly received in the notch of the carrier and the bending portion of the clamping mechanism, so it saves space and is easy to carry.

Abstract: A method of adjusting a lens may include adjusting the lens at a first focus position, and acquiring a first image of a scene through the lens. The method may further include adjusting the lens at a second focus position, and acquiring a second image of the same scene through the lens. In addition, the method may include producing respective power spectra of the first and second images, and producing a criterion representing the ratio of the power spectra to estimate a focus error of the lens.

Abstract: A swivel mount locking apparatus is configured to mount a camera system onto a target user, an object, or a surface. The camera system is mounted on a swivel component which can be rotated to a variety of different positions relative to a base component. To fix the camera position, a locking protrusion of a release lever in the base component is compressibly inserted into a detent located on the swivel component. When a new orientation of the camera system is desired, a user may forcibly pivot the release lever away from the swivel component to decouple the locking protrusion from the detent. The user can then rotate the mounted camera system and the swivel component to the new orientation relative to the base component. At the new orientation, the user may recouple the locking protrusion of the release lever into a different detent of the swivel component, thereby fixing the camera system into the desired, new orientation.
