Abstract
A method for image stabilization of a video stream captured by a panable and/or tiltable video camera the method comprising: generating a motor position signal, Y, of a pan/tilt motor of the video camera; generating a gyro signal, Y, of a gyroscopic sensor of the video camera; generating a reference signal from a predetermined movement curve of the pan/tilt motor of the video camera, the reference signal is a reference on how a pan/tilt operation of the video camera is made without shaking of the video camera; from the motor position signal, Y, and the gyro signal, Y, generating a combined signal, Y, according to: Y=F*Y+F*Y, wherein Fis a low pass filter and Fis a high pass filter; and performing image stabilization on the video stream based on a difference between the combined signal, Y, and the reference signal.
