Patent ID: 7653294

Claim:
An image blur correction apparatus, comprising: a correction lens capable of moving in a given direction perpendicular to an optical axis of a lens system which includes one or more lenses; first guide means for guiding said correction lens in a first direction perpendicular to the optical axis of the lens system; second guide means for guiding said correction lens in a second direction perpendicular to the optical axis of the lens system and also to the first direction; first driving means for moving said correction lens along said first guide means; second driving means for moving said correction lens along said second guide means; position detection means for detecting the position of said correction lens; said first and second driving means including first and second coils, a magnet configured to apply magnetic force to said first and second coils, and a yoke configured to support said magnet, said first and second coils being disposed in an intersecting relationship with each other and in an overlapping relationship with each other such that the direction of propelling force generated by a propelling force generation portion of said first coil and the direction of propelling force generated by a propelling force generation portion of said second coil are directed to the first direction and the second direction, respectively, and said position detection means detecting the magnetic force of said magnet to detect the position of said correction lens; and magnetic force uniformization means provided on at least one of said magnet and said yoke for substantially uniformizing the magnitude of the magnetic force, wherein said magnetic force uniformization means includes at least one of a recess or a projection provided on at least one of said magnet or said yoke.
