By transferring electric charges in a vertical register of a CCD imager,we have made a new imagestabilizing method.Furthermore,we have measured its effect.A small digital still camera(DSC),such as the camera module that is employed in mobile phones,needs image-stabilizing means that are both low-cost and durable.With this method,multiple short exposures of an object are taken and electric charges in the vertical register are added to make non-blurring still pictures.The first exposure in the vertical register is transferred upward or downward until the next one is read out in the same direction of a moving optical image in order to automatically add the same object.Miniaturized cameras can thus be made much more cheaply than previously because flame memory and calculations are not needed to detect motion vectors.
