Optical die set, camera and mobile terminal equipment

Abstract

The invention discloses an optical module, a camera and a mobile terminal device. The optical module comprises a lens, a lens driving component, a driving control component and a vibration transducer, wherein, the vibration transducer is used for detecting vibration / jitter of the optical module, the camera or the mobile terminal device and transmitting detected signals to the driving control component; the driving control component generates corresponding vibration / jitter compensation signals according to the detection signals of the vibration transducer and drives the lens to perform vibration / jitter compensation motion through the lens driving component. The camera and the mobile terminal device apply the optical module. The optical module, the camera and the mobile terminal device not only have autofocus function but also increase shock-proof function and overcome the defect that the image resolution is affected by vibration / jitter of the optical module, the camera or the mobile terminal device.

Description

technical field [0001] The invention relates to an optical system, in particular to an optical module, a camera and a mobile terminal device using the optical module. Background technique [0002] With the continuous development of digital technology, the performance of cameras has also been continuously improved. In order to enable the object to be photographed to form a clear image in the camera, it is often necessary to use a lens actuator in the camera to control the position of the lens or move the lens to achieve good focus. At present, this process is usually automatically completed by the control circuit. Therefore, this function is called autofocus. The main key is to control the movement of the lens along the optical axis of the lens to change the distance between the lens and the camera sensor.

AI Technical Summary

Problems solved by technology

[0003] Currently popular digital cameras are usually smaller and more casual in use. Usually there is no corresponding fixing device such as a tripod to fix it when shooting, so it is unavoidable to be affected by the vibration / shake of the photographer's hand during shooting, thus affect the clarity of the image

Although the auto-focus function can meet the requirements of image clarity in most occasions, however, in some occasions where high-definition images are required, only the auto-focus function is not enough to meet the needs
