Novel anti-shake pan-tilt for camera and anti-shake method

Abstract

The invention relates to a novel anti-shake pan-tilt for a camera and an anti-shake method. According to the technical key points, the novel anti-shake pan-tilt for the camera comprises a base, a protective shell, a frame unit, a vibrator unit, a pre-pressing unit and a signal position sensing unit, wherein the frame unit comprises an outer frame located at the inner side of the base and an inner frame arranged at the inner side of the outer frame; the vibrator unit comprises an annular piezoelectric ceramic vibrator assembly for enabling the outer frame to rotate along a first shaft relative to the base and a second annular piezoelectric ceramic vibrator assembly for enabling the inner frame to rotate along a second shaft relative to the outer frame; the first annular piezoelectric ceramic vibrator assembly is arranged between a retaining wall of the base and the side wall of the outer frame; the second annular piezoelectric ceramic vibrator assembly is arranged between the other side wall of the outer frame and the side wall of the inner frame; and the first shaft is perpendicular to the second shaft . According to the novel anti-shake pan-tilt for the camera, the problem that an existing anti-shake device for a pick-up lens cannot eliminate imaging blurring caused by shake and rotation of the lens in multiple directions, the anti-shake pan-tilt has the advantages of being high in response speed, high in load capacity, large in anti-shake angle, resistant to electromagnetic interference and the like, and the imaging quality is greatly improved.

Description

technical field [0001] The invention relates to the technical field of camera automatic focusing, in particular to a novel camera anti-shake platform and anti-shake method, which are suitable for mobile camera equipment. Background technique [0002] Because the voice coil motor has the advantages of simple structure, small size, low energy consumption, no noise, high acceleration, fast response, accurate displacement and low price, so for the automatic focusing device of the camera, the automatic focusing of the voice coil motor The function is still the most cost-effective solution. By fixing the optical lens on the voice coil motor drive carrier, the carrier acts as the power unit for lens movement, and connects the voice coil motor carrier and the housing through an elastic structure. When the motor is energized, the carrier will move linearly along the optical axis of the lens, thereby Realize automatic focus function. [0003] At present, the anti-shake device of the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a novel camera anti-shake platform and anti-shake method with a reasonable structure and reliable use, so as to solve the problem that the existing camera lens anti-shake device cannot eliminate the imaging blur caused by the shaking and rotation of the lens in multiple directions It can realize the function of multi-axis anti-shake with large load and large angle. It has the advantages of fast response speed, strong load capacity, large anti-shake angle, and anti-electromagnetic interference, which greatly improves the imaging quality.
