This invention provides an image processing apparatus that corrects an image blur by using a plurality of images acquired by image capturing means. A short connector sleeve having sockets defined in both ends that frictionally receive the truncated shank of the wrench head segment is provided so that two wrench heads may be attached to opposite ends of the sleeve to form an open end wrench, a box end wrench, or a combination wrench of standard size. The dielectric layers are further separated by a heat resistant film layer such that the capacitor exhibits excellent short circuit resistance.
