1. A method of a digital signal processor for motion triggered image stabilization, comprising: computing block projection vectors of a frame; using horizontal and vertical sums; performing motion estimation utilizing projection vectors with the shifted versions of the projection vectors from a previous frame; performing temporal IIR filter on the motion vector; calculating the maximum horizontal and vertical motion vectors; obtaining exposure time and the gain based on the resultant motion; returning the exposure time and the gain to the auto-exposure system; utilizing the returned exposure time and gain; and producing a frame with less motion blur.
