A shake detection device detecting a camera shake amount generated when photographing a subject includes a detection sensor detecting a rotation speed around a predetermined axis of the camera, a first image shift amount calculation unit driving the detection sensor to detect the rotation speed and, for an image of the subject photographed by the camera, calculating a first image shift amount as an image shift amount in a first direction based on the rotation speed, a second image shift amount calculation unit performing a predetermined image analysis on the image of the subject photographed by the camera and, for the image of the subject photographed by the camera, calculating a second image shift amount as an image shift amount in a second direction based on the analysis result, and a shake amount estimation unit estimating the camera shake amount using the first and second image shift amounts.
