It is convenient to have a camera-enabled mobile phone. When the user presses the camera button on the mobile phone by hand, it is easy to press the rib button (4) because of the tension of the user's arm muscles. Some slight movements make the captured image very easy to blur. — In similar electronic products, there is also a problem of jitter in digital cameras. The solution is to use the gyroscope (Gyr〇) to measure the sway generated by the camera and adjust the voice coil motor via the controller (Me CM VCM) Move the lens to adjust the optical axis' to solve the problem of camera blur caused by camera vibration. Although this method can effectively improve the problem of blurring of the captured image, since the mobile phone is light and thin, there is no space for the digital camera to have an anti-shake device such as a voice coil motor, so there is still no effective solution. The hand shake problem when the phone is photographed.
