Panhead

By introducing a mobile mechanism into the gimbal, the camera device is moved to the center of gravity or the position of the main point of the lens to align with the axis of rotation, which solves the problems of reduced rotation speed and increased rise time caused by deviation of the center of gravity of the rotation in traditional gimbals, achieving a more efficient Rotation and image quality improvements.

Embodiment Construction

[0027] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0028] Hereinafter, a description will be given of a first embodiment of the present invention.

[0029] figure 1 is a front view of a pan / tilt with a camera (in a principal point position aligned state) as a pan / tilt according to the first embodiment of the present invention. figure 2 is the top view of the gimbal with camera, image 3 is the side view of the gimbal with camera.

[0030] Such as Figure 1 to Figure 3 As shown, the pan / tilt with camera basically consists of a camera unit 1 , a pan / tilt 50 , and connecting rods 11 , 12 , 17 and 18 . The camera unit 1 is provided with a front lens holder 10 . The cloud platform 50 is composed of a base rotating unit 19 and a base fixing unit 31 . figure 1 A pan / tilt with a camera is shown in a state where the lens principal point position of the camera unit 1 is aligned with the rot...

Abstract

A pan / tilt capable of properly operating an imaging device with a simple mechanism. The fixed unit is provided on the base of the pan head with camera. The base rotating unit is supported on the base fixing unit for rotation in a plane parallel to the upper surface of the base fixing unit. Two parallel link mechanisms connect the camera unit and the base rotation unit, and move the camera unit to a predetermined position capable of maintaining the direction of the optical axis of the camera unit according to the use mode of the camera unit.

Description

technical field [0001] The present invention relates to a head for rotatably supporting a camera unit. Background technique [0002] In the past, there has been proposed a technique concerning a pan head for rotatably supporting a camera unit, which always aligns the position of the principal point (central point) of the lens of the camera unit with the axis of rotation of the camera unit and provides for panoramic photography. An effective component (a component for making a connection between a plurality of images look natural) (for example, see Japanese Patent Application Laid-Open No. 2000-147643). According to the proposed technique, during panorama photography, the lens principal point position is aligned with the rotation axis of the camera unit according to the movement of the lens principal point position at the time of a focusing operation or a zooming operation. [0003] However, the conventional technology described above has a problem in that the position of th...
