Portable Device Having Vibration Reduction Function and Vibration Reduction Method Thereof
A portable device includes a central processing unit, a vibration sensor to sense vibration of the portable device, an image processing unit to process image data, and a memory unit storing a vibration reduction module. The vibration reduction module includes a vibration signal collecting sub-module to collect a vibration signal of the portable device, a filter sub-module to filter noise of the vibration signal, a vibration offset calculating sub-module to calculate a vibration offset of the portable device according to the filtered vibration signal, a vibration compensation calculating sub-module to calculate a compensation value corresponding to the vibration offset of the portable device, and an image controlling sub-module to control images of the portable device to move a distance which is equal to the compensation value via the image processing unit, to make the images of the portable device keep a fixed position.
