imaging device

Abstract

The invention relates to an imaging device, which includes a camera module, a fixed frame, a movable frame, a rolling ball, a displacement sensing element, a magnetic driving unit and an elastic element. The movable frame is located in the fixed frame and accommodates the camera module and includes a first outer surface, a second outer surface, a third outer surface and a fourth outer surface parallel to the optical axis of the camera module. The rolling ball is rotatably connected to the fixed frame and the movable frame. The displacement sensing element is disposed on the fourth outer surface and is used for sensing the shaking of the camera module. The magnetic driving unit includes a first magnetic component disposed on the fixed frame and a second magnetic component disposed on the first, second and third outer surfaces, the first magnetic component and the second magnetic component are used to interact to generate a driving force Thereby, the movable frame is driven to rotate relative to the fixed frame with the rolling ball as the fulcrum. The elastic element is elastically connected to the fixed frame and the movable frame.

Description

technical field [0001] The invention relates to imaging technology, in particular to an imaging device with an anti-shake function. Background technique [0002] With the continuous development of digital imaging technology, the body of the imaging device is often small and light, which is likely to cause hand shake and blur the image. The following three situations are likely to produce blurred images: 1. When shooting with a long focal length, since the long lens will amplify the amplitude of the imaging device, slight shaking will also cause greater blur, so the impact of hand vibration on the image clarity is greater than that of using The wide-angle lens is obvious; second, when shooting in low-light environments, in low-light environments such as indoors and dusk, the imaging device will adjust the shutter speed slower to increase the amount of light entering, so hand shake is more likely to occur; third, macro shooting, fine objects When the lens is magnified at a hi...

[0002] With the continuous development of digital imaging technology, the body of the imaging device is often small and light, which is easy to cause hand shake and blur the image

The following three situations are likely to produce blurred images: 1. When shooting with a long focal length, since the long lens will amplify the amplitude of the imaging device, slight shaking will also cause greater blur, so the impact of hand vibration on the image clarity is greater than that of using The wide-angle lens is obvious; second, when shooting in low-light environments, in low-light environments such as indoors and dusk, the imaging device will adjust the shutter speed slower to increase the amount of light entering, so hand shake is more likely to occur; third, macro shooting, fine objects When the lens is magnified at a high magnification, slight vibrations will become quite obvious

These conditions can cause jitter, making the image blurred
