Claim 11:
12. The apparatus according to claim 11, wherein
the signal processing circuit is configured to generate a plurality of calculated amplitudes, the plurality of calculated amplitudes comprising an alternation of amplitudes calculated using the first plurality of predetermined phase values and the second plurality of predetermined phase values; and the apparatus further comprises:
an amplitude correction unit configured to receive the plurality of calculated amplitudes and to calculate a plurality of corrected output amplitudes by combining pairs of temporally adjacent calculated amplitudes of the plurality of calculated amplitudes; and wherein
the amplitude correction unit is configured to select between a corrected output amplitude of the plurality of corrected output amplitudes and a substantially contemporaneous calculated amplitude of the plurality of calculated amplitudes used to calculate the corrected output amplitude, the selection being in response to the comparison of the measure of inter-frame motion with the predetermined motion threshold.
