Patent ID: 8577214

Claim:
A shake correction apparatus comprising: a shake detection unit which detects a shake; a calculation unit which calculates a shake correction amount for correcting an image blur based on an output from said shake detection unit; a shake level determination unit which determines a shake level of the shake based on an output from said shake detection unit, wherein the shake level determination unit determines the shake level of the shake based on whether an absolute value of the shake correction amount exceeds the predetermined value or not, the predetermined value having a plurality of threshold values; and a shake correction unit which corrects the image blur based on the shake correction amount, wherein the correction unit moves to the shake correction center as the shake level becomes larger, wherein said shake level determination unit includes a counter which counts up while an absolute value of an output value of said shake detection unit exceeds a predetermined threshold, and counts down while the absolute value of the output value of said shake detection unit is not larger than the threshold, and said shake level determination unit determines the shake level based on a count value of the counter.
