Abstract: Depth information generating section generates depth image information representing the class of the depth of each pixel in two-dimensional image information outputted from an image input section, according to depth information outputted from an input section. A stereoscopic image information generating section generates stereoscopic image information, based on the depth image information and the two-dimensional image information. Thereafter, an image for the left eye and an image for the right eye read by an image information output section are alternately displayed on the screen of an image display section under the control of a gate. In synchronization with the change-over operation of alternately displaying the image for the left eye and the image for the right eye, the stereoscopic section controls the opening and closing of liquid crystal shutters of liquid crystal shutter glasses.
