Claim Text:
1. A method for estimating a blurriness value, comprising acquiring a series of at least two frames within a period of time greater than a given exposure time to be used for acquisition of a still picture being distinct from the at least two frames; grouping said at least two frames in at least one couple of frames; determining, for each of the at least one couple of frames of the series, first and second displacement values corresponding to a displacement according to a first direction and a second direction, between a first frame and a second frame of a couple of frames; determining a first blur measure for one direction among said first and second directions by calculating a metric based on the first and second displacement values for each of the at least one couple of frames of at least a subset of said series; determining a second blur measure for the other direction among the first and second directions by calculating a metric applied to said first and second displacement values for each of the at least one couple of frames of the series of frames; and determining a blurriness value based on said first and second blur measures.
