Abstract:
1. An image blurring correction apparatus comprising: a correction member configured to correct image blur; a shake detection unit configured to detect a shake of the apparatus and output a shake signal; a first generation unit configured to generate first shake amount data based on the shake signal; a second generation unit configured to generate, based on the shake signal, second shake amount data with which a higher shake correction effect than a shake correction effect of the first shake amount data can be obtained; a selection unit configured to select the first shake amount data or the second shake amount data based on the shake signal; a calculation unit configured to calculate a shake correction amount which is a moving amount of the correction member using the shake amount data selected by the selection unit; and a determination unit configured to determine whether or not the apparatus is in a constant point capturing state in which a panning control is turned off, based on whether or not a magnitude of the shake signal is in a predetermined shake signal magnitude range and the shake correction amount is in a predetermined shake correction amount range, wherein the selection unit provides the calculation unit with the second shake amount data if the determination unit determines that the apparatus is in the constant point capturing state, and provides the calculation unit with the first shake amount data if the determination unit determines that the apparatus is not in the constant point capturing state.
