An image recording device having a projected viewfinder is described that projects individual, or multiple sets of synchronized framing beams onto a target image that are coaxially aligned with the field of view of the camera. The set of framing beams is projected onto the target image beyond the scope of the field of view being recorded by the image recording device but still within the field of vision of the operator of the device. In this way, the operator of the image recording device will be able to clearly see the framing beams identifying the limits of the recorded areas, while not having any portion of the field of view of the image recording device obscured by the framing beams themselves.

A camera device comprises: a bracket; a camera module coupled to the bracket to be rotatable about a first axis; a viewing angle adjustment member including a side coupled to the bracket and an opposite side coupled to the camera module; and a support member coupled to the bracket, wherein the side of the viewing angle adjustment member includes a hook portion arranged between the bracket and the support member.

A method and an apparatus to provide a service using a sensor and image recognition in a portable terminal that supports Augmented Reality (AR). The method includes determining whether the portable terminal is parallel to ground using an acceleration sensor. When the portable terminal is parallel to the ground, either a map including nearby Point Of Interest (POI) information or constellation information is displayed.

[Object] To provide an information processing apparatus that can adjust a position of a device to make an eyeball position of a user agree with a visual field center of a display surface.

[Solution] There is provided an information processing apparatus including: an eyeball position estimation unit configured to estimate an eyeball position of a user in a pupil-corneal reflection method on the basis of a captured image including an eye of the user captured when the eye of the user looking at a display surface is irradiated with light; a discrepancy estimation unit configured to estimate an amount of discrepancy between an eyeball position on the display surface and a visual field center of the display surface, the eyeball position being identified on the basis of the eyeball position; and an operation instruction unit configured to issue an operation instruction to adjust a position of a device including the display surface on the basis of the estimated amount of discrepancy.

A camera rotation device includes a connection tube, a rotation annulus, a resistance annulus, an oil film, and a driver. The rotation annulus and the resistance annulus are respectively sleeved at two opposite sides of the connection tube and are fixed to each other. The connection annulus includes a resistance portion, and the rotation annulus has a plurality of teeth in a ring-shaped arrangement. The oil film is arranged in a space surroundingly defined by the rotation annulus, the resistance annulus, and the resistance portion. The driver is engaged with at least one of the teeth, and a relative position of the driver and the connection tube is fixed. The driver is configured to rotate at least one of the teeth, such that the rotation ring and the resistance annulus are jointly rotated relative to the resistance portion, and generate a rotation resistance force through the oil film.

A lens apparatus of the present invention includes an optical unit that moves integrally in a direction of an optical axis and a biasing unit that applies a first force and a second force to the optical unit at different positions around the optical axis. In the lens apparatus, a direction of a component of the first force in the optical axis direction and a direction of a component of the second force in the optical axis direction are opposite to each other.
