Zusammenfassung:In apparatus for transforming an input image into a wavering output image, an attenuation standard position and an attenuation range are set on the basis of the attenuation standard position, and three-dimensional shape data, representing the shape based on the produced transform address data by adding the address data of the input image to an offset value changing in accordance with the distance from a standard position using a predetermined cyclic function, is generated. Then, an attenuation value changing in accordance with the distance from the attenuation standard position after the value rises in the attenuation range is set. The offset value is weighted by this attenuation value and the input image is mapped on the shape such that the amplitude of a ripple changes gradually in accordance with the distance from the attenuation standard position.
