Abstract:
An image blur correction apparatus connectable to each of (i) a camera body of a first camera body type carrying a first image blur detection sensor, which outputs a first blur signal having a first attribute, and (ii) a camera body of a second camera body type carrying a second image blur detection sensor, which outputs a second image blur signal having a second attribute different from the first attribute, said apparatus comprising:an image blur correction unit, which performs an image blur correction operation based on a driving signal having an attribute that corresponds to the first attribute of the first blur signal; receiving means, which receives a blur signal from a camera body connected to said apparatus; a conversion circuit, which converts the second attribute of a second blur signal received by said receiving means to a signal having a corresponding attribute that corresponds to the first attribute of the first blur signal, when the apparatus is connected to a camera body of the second camera body type; and a producing circuit, which produces a driving signal based on the signal converted by said conversion circuit when said apparatus is connected to a camera body of the second camera body type, and produces a driving signal based on a first blur signal received by said receiving means without use of said conversion means when said apparatus is connected to a camera body of the first camera body type, wherein each of the first and second attributes, which are different from each other, includes one of an acceleration attribute, a velocity attribute, and a displacement attribute.
