Abstract
A method and apparatus motion triggered image stabilization. The method includes computing projection vector for at least a portion of a frame of an image using horizontal and vertical sums, performing motion estimation utilizing projection vector with the shift of the projection vector from a previous frame, performing temporal IIR filter on the motion vector, calculating the maximum horizontal and vertical motion vectors, obtaining exposure time based on the horizontal and vertical motion vectors and the gain, returning the exposure time and the gain to the auto-exposure, utilizing the returned exposure time and gain, and producing a frame with less motion blur.
