Abstract
During the exposure of an image sensing device, the optical image of a subject is rotated by one revolution or a plurality of revolutions relative to the sensing surface of the image sensing device along a plane perpendicular to the plane of the image sensing device while the orientation of the image is maintained substantially horizontally and vertically with respect to the sensing surface. The radius r of this rotation is set so as to satisfy the equation ##EQU1## where .rho. represents trap frequency and .omega..sub.0 the initial zero point of a Bessel function of the first kind of order zero.
