• the detection device detecting positions of eyes of a user based on photographed images which are successively acquired from a camera which images the eyes of the user at imaging time intervals,
• the three-dimensional display device comprising a display panel configured to display a parallax image and emit image light corresponding to the parallax image;
• a parallax barrier comprising a surface configured to define a direction of the image light;
• an acquisition section configured to successively acquire a plurality of pieces of positional data indicating positions of eyes of a user from a detection device which is configured to detect positions of the eyes based on photographed images which are successively acquired from a camera which is configured to image the eyes of the user at imaging time intervals;
• a memory configured to store the plurality of pieces of positional data which are successively acquired by the acquisition section;
• and a controller configured to output predicted eye positions of the eyes as of a time later than a current time based on the plurality of pieces of positional data stored in the memory, and cause each of subpixels of the display panel to display the parallax image, based on the predicted eye positions,
• the controller being configured to carry out, in accordance with a first predicted eye position, generation processing for generating a left-eye image and a right-eye image to be displayed, and
• carry out, in accordance with a second predicted eye position, which is different from the first predicted eye position, synthesis processing for combining the left-eye image and the right-eye image into a parallax image.
