Digital image stabilisation for mobile devices based on real-time phase correlation with support for the SIMD data path is presented. By using sub-image projection, the phase correlation process can be fitted within the real-time criteria. The proposed method acquires a global motion vector from a sub-image at the centre of the viewport, which is projected onto the x- and y-axes on which the phase correlation is performed. The projection stage and the FFT calculations are accelerated using the Neon SIMD engine that is facilitated in the ARM CPU. With this acceleration, the global motion vector for each image frame can be calculated in<20 ms on the Samsung Galaxy S smartphone running at 1.0GHz.
