Automatic image stabilization device

An automatic image stabilization device arranged to detect the shaking of images through an image signal produced from image sensing means and to correct said shaking of images, comprising:

• a) movement detecting means for obtaining information on image movements taking place at a plurality of points of an image sensing plane;
• b) mode discriminating means for discriminating photographing modes from each other;
• and
• c) weight setting means arranged to attach weight to information on movement taking place in each of blocks set on said image sensing plane and to vary the degree of weight according to the output of said mode discriminating means;
• d) computing means for computing the degree of image movement on the basis of movement information which is weighted by said weight setting means;
• and
• e) correction means including a correction optical system which is arranged to offset said image movement according to the output of said computing means.
