Minitype image stabilizing device

Abstract

The invention discloses an image stabilizing device which comprises a base plate, a bearing platform which is movably arranged on the base plate and used for carrying a sensing element of an image, an anchor point which is fixedly arranged on the base plate; a conductor pad which is used for coupling with an image disposing circuit and is fixedly arranged on the anchor point, an elastic cantilever which is arranged between the anchor point and the bearing platform, a lead which is arranged on the elastic cantilever and used for coupling the sensing element of the image, with one end being coupled with the conductor pad and the other end extending to the bearing platform by way of the elastic cantilever, and a micro-actuator which is arranged between the bearing platform and the base plateand coupled with a control circuit of the micro-actuator and is used for adjusting the position of the bearing platform corresponding to the base plate according to control signals sent by the control circuit of the micro-actuator.

Description

technical field [0001] The present invention relates to an image stabilizing device, more specifically, the present invention relates to a miniature image stabilizing device. Background technique [0002] Nowadays, many digital cameras emphasize the function of anti-shake. One of the methods is to install an image stabilization device on the camera's image sensing element (such as CCD, CMOS), so that when the camera shakes, the image sensing element can move equally, and the image is formed on the image sensing element The situation will not be affected by the vibration and provide user convenience. However, the size of today's digital cameras is getting smaller and smaller, so the size of the image stabilization device needs to be smaller. Therefore, the prior art proposes an image stabilization device using MEMS technology. [0003] Please refer to figure 1 . figure 1 It is a schematic diagram of an image stabilization device 100 using MEMS technology. The image stab...

Problems solved by technology

However, these two procedures are relatively cumbersome for the production process, so it is not convenient for production.

[0006] In addition, in the image stabilization device 100 of the prior art, since the cable 140 is coupled to the image sensing element 160, when the carrier platform 150 and the substrate 170 have a relative displacement, the cable 140 will affect the movement of the carrier platform 150. make an impact

For example, when the cable 140 is deformed, it will also generate elastic force, which will affect the movement of the carrying platform 150, and the amount of elastic force generated by the cable 140 is unpredictable.

Therefore, the final moving degree of the carrying platform 150 will also be affected by the cable 140, and cannot reach the expected position.
