1. A shake detection apparatus comprising:

  • shake detection sensor means for detecting a shake state to output a shake detection signal;

    high-pass filter arithmetic means for performing high-pass filter arithmetic processing, thereby removing drift and offset components contained in the shake detection signal output from said shake detection sensor means;

    time constant increasing means for shifting an upper limit frequency for high-pass filter arithmetic processing by said high-pass filter arithmetic means from a high-frequency side to a low-frequency side;

    large-shake-signal determination means for detecting a large shake signal state on the basis of an output from said high-pass filter arithmetic means; and

    small-time-constant resetting means for shifting the upper limit frequency for high-pass filter arithmetic processing by said high-pass filter arithmetic means to the high-frequency side when the large shake signal state is detected by said large-shake-signal determination means.
