A shake detecting apparatus includes a shake detecting sensor for outputting signals resulting from shake given to the shake detecting apparatus. In the case of application, for example, to an image pickup apparatus, the shake detecting sensor detects camera shake given to the image pickup apparatus. The shake detecting apparatus further includes an first integrating section for integrating the signals outputted from the shake detecting sensor, a second integrating section for integrating outputs of the first integrating section, and a correcting section for correcting the outputs of the first integrating section using outputs of the second integrating section after the lapse of a specified period following a specified timing.
