Embodiment 1

[0027] see Figure 4 , the present embodiment provides a camera, including a total reflection mirror assembly 10, a lens assembly 20 and a circuit assembly 30; the total reflection mirror assembly 10 includes a total reflection mirror 11 and a first shape memory alloy metal disposed on the total reflection mirror 11 Wire 12, the lens assembly 20 includes a lens, and the circuit assembly 30 includes a tilt detector 31 and a drive chip 32; wherein the tilt detector 31 is used to detect the shaking parameters of the total reflection mirror 11 shaking, and convert the shaking parameters into a first electrical signal To transmit; the drive chip 32 is used to receive the first electrical signal, calculate the compensation displacement according to the first electrical signal, and output the first current to the first shape memory alloy wire 12 after calculation; the first shape memory alloy wire 12 is used to generate the first pulling force under the action of the first current to...

Embodiment 2

[0059] see Figure 12 , this embodiment provides a camera anti-shake method, the anti-shake method is suitable for the camera in the first embodiment, the anti-shake method includes:

[0060] Step S1: Detect the shaking parameters of the shaking of the total reflection mirror 11, and convert the shaking parameters into a first electrical signal for transmission.

[0061] Step S2: receiving the first electrical signal, calculating the compensation displacement according to the first electrical signal, obtaining a first current according to the compensation displacement, and outputting the first current to the first shape memory alloy wire.

[0062] Step S3: the first shape memory alloy wire 12 generates a first pulling force under the action of the first current, and pulls the total reflection mirror 11 to perform a position compensation movement.

[0063] When the total reflection mirror 11 shakes, the lens shifts accordingly, so as to reduce the impact caused by the shake. ...

Abstract

Embodiments of the invention provide a camera and an anti-shake method of the camera and relate to the camera shooting technology field. By using the camera and the method, cost of the camera is reduced and a camera structure is simplified. A total reflection mirror component of the camera comprises a total reflection mirror and a first shape memory alloy metal wire arranged on the total reflection mirror. A lens component comprises a lens. A circuit component comprises an inclination detection instrument and a driving chip. The inclination detection instrument is used for detecting a shaking parameter of total reflection mirror shaking and converting the shaking parameter into a first electric signal so as to transmit. The driving chip is used for receiving the first electric signal, calculating a compensation displacement amount according to the first electric signal and outputting a first current to the first shape memory alloy metal wire after calculation. The first shape memory alloy metal wire is used for generating a first tensile force under a first current effect so as to pull the total reflection mirror to move towards a compensation position.

Description

technical field [0001] The invention relates to the technical field of photography, in particular to a camera and a camera anti-shake method. Background technique [0002] A periscope optical zoom (Optical Image Stabilization, referred to as OIS) camera is a camera that uses optical zoom technology to shoot. It has the characteristics of changing the focal length and keeping the size of the image plane. figure 1 , the OIS camera uses a total reflection prism 100 to turn the light 200 degrees to 90 degrees before entering the lens, changing the original front and rear adjustment focal length into left and right adjustment, reducing the storage space of the camera device in the thickness direction, and realizing the ultra-high performance of the camera device thinning. [0003] The common OIS camera has anti-shake function to improve the shooting quality. The OIS camera is equipped with a voice coil motor, a magnet, a coil and a Hall sensor. The voice coil motor energizes th...
