[0036] Hereinafter, the present invention will be further described in detail with reference to the drawings and specific embodiments of the specification.
[0037] The electronic image stabilization method proposed in this embodiment does not require an additional motion compensation sensor to obtain the motion state, but introduces the motion estimation method of video coding technology. The global relative motion vector of each frame is calculated by the motion estimation method, so as to obtain the global relative motion of the current frame. Motion vector MV N The estimated value of, and the global relative motion vector MV of the previous several frames 1 , MV 2 ,..., MV N-1 Predict the global relative motion vector MV of the current frame N . If MV N And MV NIf the difference is greater than a given threshold T, it is considered that jitter has occurred and motion compensation is required; otherwise, the original image is maintained without compensation. The principle is as...
