A posture maintaining device for a 360&#xb0; camera according to an embodiment of the present invention may comprise: a first correcting portion comprising a seating portion, on which a camera having a 360&#xb0; view angle is seated, the first correcting portion being able to make a rotational movement about a first direction; a second correcting portion arranged on one side of the first correcting portion to be able to make a rotational movement about a second direction, which is different from the first direction; a third correcting portion arranged on the lower end of the second correcting portion to be able to make a rotational movement about a third direction, which is different from the first or second direction; and a counterbalance connected to the first correcting portion and configured to guide the camera so as to remain horizontal. A posture maintaining device for a 360&#xb0; camera according to an embodiment of the present invention corrects the inclination in real time when images are taken through a camera having a 360&#xb0; view angle, making it possible to implement pictures or moving images without vibration. Moreover, when images are taken through a camera having a 360&#xb0; view angle, a gimbal with minimized image blocking is implemented, making it possible to obtain images with minimized interference.

Horizontal posture maintaining device and posture maintaining device driving method

A photographing apparatus is provided. The photographing apparatus includes a photographing unit comprising a photographing sensor and a lens unit configured to focus image light onto the photographing sensor, a first driver configured to drive the photographing sensor to perform a first rotation about a first axis that is coincide with an optical axis of the lens unit, and a second driver configured to drive the photographing unit and the first driver to perform a second rotation about a second axis that is perpendicular to the first axis.

Photographing apparatus, unmanned aerial vehicle having the photographing apparatus, and attitude control method for the photographing apparatus

An autofocus driving unit for moving a lens holder supporting at least one lens in an optical axis direction with respect to an image sensor. The autofocus driving unit includes: a lead screw that has a length in a direction parallel to an optical axis and rotates to move the lens holder in the optical axis direction; a first driving source that rotates the lead screw so that the lead screw moves in multiple integers of a first distance in the optical axis direction and that comprises a rotor mounted in an outer circumference of the lead screw and a stator that is spaced apart from the rotor and rotates the rotor; and a second driving source that moves the lead screw and the rotor in a first direction that is parallel to the optical axis with respect to the stator so that the lens holder is moved by a second distance that is different from the first distance in the optical axis direction.

Autofocus driving unit and photographing apparatus having the same

A horizontal-posture maintaining apparatus is provided. The apparatus includes a barrel, a cover unit provided on a side surface of the barrel, a first driver provided in the cover unit, for rotating the barrel in a first direction (around an X axis) to keep the barrel in horizontal posture, a second driver provided in the cover unit, for rotating the cover unit in a second direction (around a Y axis) to keep the barrel in the horizontal posture, and a controller for controlling rotation of the first and second drivers.

Horizontal-posture maintaining apparatus

A direct current (DC) motor including: a cylindrical frame, at least one end of which is open; a cylindrical end cover including an opening configured to block the at least one open end; a rotor including a rotor shaft supported by the frame and the end cover, and a rotor core installed on the rotor shaft; a commutator installed on the rotor shaft and arranged on one end of the rotor core; a cover unit installed on the rotor shaft, arranged between the rotor and the commutator, and including at least one location detection device; and a rotation detection unit installed in the end cover and configured to detect the at least one location detection device.

DC motor including a rotation detection unit

A step motor includes a plurality of stator cores. Each of the stator cores have a coil unit coiled therearound. The step motor includes a rotor that includes a rotation shaft and a plurality of permanent magnets and is configured to rotate by magnetic interaction between the stator cores and the permanent magnets. The step motor also includes a plurality of conducting parts on one cross-sectional surface of the rotor. The step motor further includes a printed circuit board (PCB) including electric elements that are arranged at certain positions and are disposed to face the conducting parts. The conducting parts and the electric elements are configured to electrically or magnetically interact as the rotor rotates to change electrical signals generated by the electric elements.
