Problems solved by technology

[0006] In view of the above problems, the present invention proposes an imaging device, which can reduce the space of the optical anti-shake circuit on the one hand to meet the market demand, and on the other hand can solve the problems existing in the prior art due to the optical anti-shake circuit and the central processing unit. Cross-platform operation between devices requires further processing before they can be connected to each other, thus increasing the cost

Abstract

The utility model discloses a camera device comprising a compensation unit, a first position sensor, a second position sensor, a first vibration detecting unit, a second vibration detecting unit, a first actuator, a second actuator and a central processor. The central processor comprises a first servo driving circuit, a second servo driving circuit and a hand-vibration prevention processing unit; the hand-vibration prevention processing unit is used for processing vibration signals and position signals respectively to drive the first actuator and the second actuator, so as to adjust the positions of a compensation unit in first and second directions and further compensate the shaking of the camera device in the first and second directions, wherein the vibration signals are respectively output by the first and second vibration detecting units, and the position signals are respectively output by the first and second position sensors and respectively pass through the first and second servo driving circuits.

Description

technical field [0001] The present invention relates to an imaging device, in particular to an imaging device in which circuits required for anti-hand shake are integrated into a central processing unit and an imaging device in which circuits required for driving an optical anti-hand vibration mechanism unit are integrated into peripheral drive chips. device. Background technique [0002] With the rapid development of the camera industry, cameras have been developed towards thinner and smaller cameras. Due to the reduction in size and weight of cameras, users are likely to cause hand shake when operating the camera, resulting in blurred images. Therefore, in order to prevent the blurred image caused by the user's hand vibration, many cameras currently on the market can compensate for the blurred image caused by the user's hand vibration. [0003] Anti-handshake methods are mainly divided into electronic anti-handshake and optical anti-handshake. Electronic anti-shake is to...
