<P>PROBLEM TO BE SOLVED: To provide an image output device having a circuit that forms and outputs an interpolation image other than an original image, the image output device minimizing image quality deterioration caused by disturbance of a stationary title portion, thereby: achieving a circuit for a higher image quality; eliminating the need to add a special buffer memory to mount the circuit. Ž<P>SOLUTION: When an interpolation image is generated from an interpolation vector based on an original image in an interpolation image forming circuit 6 with respect to a stationary title area detected by a stationary title detection circuit 3, the value of an interpolation vector relative to a pixel determined as the stationary title area is used as 0. This prevents a stationary title from being pervaded and deleted by a surrounding dynamic motion picture portion. Further, if a pixel specified by an interpolation vector is in a stationary title area when an interpolation image is generated by pixels outside the stationary title area, and an interpolation image is generated having an interpolation vector value as 0. This prevents pixels in the stationary title area from being located outside the stationary title area. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
