Abstract
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.
