Claim Text:
1. An image shake correcting apparatus comprising: (a) a shake detecting unit configured to detect shake and to produce a shake detection signal; (b) a calculating unit configured to calculate an image shake correction amount by acquiring the shake detection signal output from the shake detecting unit; and (c) a shake correcting unit configured to correct an image shake in accordance with the image shake correction amount calculated by the calculating unit, wherein the calculating unit comprises: wherein the calculating unit causes the offset removing unit to remove an offset component from the shake detection signal to thereby calculate the image shake correction amount from a start of an operation of the shake detecting unit until the reference value calculating unit calculates the offset reference value regarding the shake detection signal, and the calculating unit calculates the image shake correction amount from a signal obtained by subtracting the offset reference value from the shake detection signal after the reference value calculating unit calculates the offset reference value, and wherein the image shake correction amount from the signal obtained by subtracting the offset reference value from the shake detection signal does not pass by the high-pass filter.
