A three-dimensional image special effect apparatus wherein operation for setting a parameter can be performed simply and a special image can be moved smoothly to a distance only by a single manual operation of a track ball or a rotary ring is disclosed. A special image produced by an image special effect processing section is manually operated in first and second three-dimensional directions by a track ball and in a third three-dimensional direction by a rotary ring disposed along an outer periphery of the track ball. A condition in which a parameter for determining a condition of the special image can be set is established and a setting menu for setting a parameter which determines a condition of the special image is produced by a CPU. Under the control of the CPU, a cursor for designating a parameter on the setting menu is operated by way of the track ball, and a value of the parameter is set by way of the rotary ring.

Three-dimensional image special effect apparatus

In an image transforming apparatus for transforming an input image into a wavering output image, an attenuation standard position and an attenuation range measured from the attenuation standard position are selected and three-dimensional shape data are generated for representing a 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 a predetermined cyclic function. Then, an attenuation value is generated within the attenuation range, and the attenuation value changes in accordance with the distance from the attenuation standard position. 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 varies in accordance with the distance from the attenuation standard position. When the attenuation value is set to a constant value, and the offset value is weighted and such attenuation value, the input image is mapped on the shape such that the amplitude of a ripple is kept to a constant value even when the distance from the attenuation standard position changes.
