Abstract
A left eye image signal and a right eye image signal which constitute a three-dimensional image are produced from a two-dimensional image signal. The horizontal phase of the produced left eye image signal is shifted, and the horizontal phase of the produced right eye image signal is shifted. Character signals are respectively mixed with the left eye image signal and the right eye image signal. A composite image comprising the three-dimensional image and the character signal is displayed on the basis of the left eye image signal with which the character signal is mixed and the right eye image signal with which the character signal is mixed.
