An Integrated Dynamic Image Stabilizer Applied to Zooming Systems

In this paper, we propose a new integrated architecture for a dependent stabilization and zooming process. The stabilization system adapts its operational parameters from the current optical zooming status and subsequently stabilization parameters are introduced, as an additional input, to the digital zooming system for the interpolation process. With this approach the stabilization system is dynamic, with no permanent setup only for the non-zooming operation of the camera, making the whole architecture dependent and not strictly sequential. Additionally, the digital image stabilization system introduces an input to the digital zooming system in order to carry out simultaneously the image compensation and the image zooming within the interpolation procedure. Experimental results showed that the proposed integrated architecture exhibit better performance compared to the existing conventional stabilization architecture, when zooming process is employed. Furthermore, the proposed system has less computational complexity minimizing the observed latency of the conventional systems.
