Embodiment Construction
[0031] The core of the present invention is to provide a camera module. In the prior art, the camera is usually fixed by a bracket, and the bracket can rotate in multiple directions without rotating the camera. Since the bracket has multiple rotating shafts and usually requires the user to manually operate the bracket, a hand-held grip should be provided accordingly. At the same time, a space for the camera head needs to be reserved inside the bracket. The above structure will occupy a large volume. As a result, the size of the entire bracket is too large. At the same time, since the entire bracket is only provided with a rotating shaft for rotation, when the shaking direction of the entire camera module is rotating around the camera, effective anti-shake can be performed. However, if the working environment of the entire camera module is on a bumpy road, for example, and the jitter direction of the entire camera module is to jitter along any plane, the above-mentioned bracket...

The invention discloses a camera module comprising a shell sleeve, a sensor and a processor, a fixing bracket is detachably arranged in an inner cavity of the shell sleeve, and a camera is fixed to the fixing bracket, wherein the shell sleeve is provided with a coil, and the fixing bracket is made of a magnetic material; the sensor is connected with the processor, and the sensor is used for obtaining attitude parameters of the camera module and sending the attitude parameters to the processor; the processor is connected with the coil, and the processor is used for controlling the coil to generate a magnetic field according to the attitude parameters to control the fixing bracket to move; and the magnetic field generated by the coil can control the fixing bracket to move so as to counteractthe influence of jitter of the camera module to the camera and ensure that the camera arranged in the camera module generates no jitter in the case of jitter of the camera module. The invention further discloses a camera movement control method, which also has the beneficial effects.
Description
Technical field [0001] The present invention relates to the field of camera technology, in particular to a camera module and a method for controlling camera movement. Background technique [0002] With the continuous advancement of science and technology in recent years, the functions of camera modules have become increasingly powerful, and the structure of camera modules has become increasingly complex. [0003] At this stage, in some special situations, such as high-speed movement or when a stable image needs to be taken while moving, the camera module is required to have an anti-shake function to obtain stable and clear images. In addition, when the camera module is used to take a photo, the human hand will shake involuntarily, which will cause the image captured by the camera module to be unclear, which also requires the camera module to have an anti-shake function. [0004] When the camera module shakes, if the amplitude of the shake is small, the post-processing method can be ...
