Abstract
An image blur correction device tracks a feature point in a captured image, calculates feature point tracking information, and estimates a positional relationship including a depth between a subject and an imaging apparatus as three-dimensional coordinates of the feature point on the basis of the feature point tracking information and position attitude information of the imaging apparatus calculated on the basis of shake information relating to shake of the imaging apparatus. The image blur correction device also controls a degree of contribution of the feature point to the estimation of the three-dimensional coordinates. The image blur correction device corrects the position attitude information according to a result of the estimation of the three-dimensional coordinates of the feature point, calculates a target position of a shake correction lens based on the shake information and the position attitude information, and drives the shake correction lens.
