Abstract
A display device includes an image display section for left eye, an image display section for right eye, and a control section configured to expand the image data for the eyes, and cause the image display section for the eyes to display the expanded image data for the eyes. The control section acquires compressed UI image data, draws the compressed UI image data in a predetermined position of one of the image data for left eye before the expansion and the image data for right eye before the expansion, draws the compressed UI image data in a position corresponding to the predetermined position of the other of the image data for left eye before the expansion and the image data for right eye before the expansion, and performs the expansion using the image data for left eye and for right eye after the drawing.
Claims11
A display device that superimposes and displays a UI element configuring a user interface on a 3D image, the display device comprising:
- a left image display disposed in front of a left eye of the user;
- a right image display disposed in front of a right eye of the user;
- a memory storing 3D image data in which, with a lateral direction or a longitudinal direction set as a predetermined direction, one frame is configured by image data for left eye and image data for right eye compressed in the predetermined direction;
- and
- a processor or integrated circuit configured to:
- acquire compressed UI image data obtained by compressing image data of the UI element in the predetermined direction,
- draw the compressed UI image data in a predetermined position of one of the image data for left eye before the expansion and the image data for right eye before the expansion,
- draw the compressed UI image data in a position corresponding to the predetermined position of the other of the image data for left eye before the expansion and the image data for right eye before the expansion, and
- expand the compressed UI image data at the position over the image data for the left eye after the drawing and for the image data for the right eye after the drawing from the 3D image data respectively in the predetermined direction,
- cause the left image display to display the expanded image data for the left eye, and
- cause the right image display to display the expanded image data for the right eye.
A control method for a display device that superimposes and displays a UI element configuring a user interface on a 3D image,
- the display device including:
- a left image display disposed in front of a left eye of the user;
- a right image display disposed in front of a right eye of the user;
- a memory storing 3D image data in which, with a lateral direction or a longitudinal direction set as a predetermined direction, one frame is configured by image data for left eye and image data for right eye compressed in the predetermined direction,
- the control method comprising:
- acquiring, by a processor or integrated circuit, compressed UI image data obtained by compressing image data of the UI element in the predetermined direction,
- drawing, by the processor or integrated circuit, the compressed UI image data in a predetermined position of one of the image data for left eye before the expansion and the image data for right eye before the expansion,
- drawing, by the processor or integrated circuit, the compressed UI image data in a position corresponding to the predetermined position of the other of the image data for left eye before the expansion and the image data for right eye before the expansion, and
- expanding, by the processor or integrated circuit, the compressed UI image data at the position over the image data for the left eye after the drawing and for the image data for the right eye after the drawing from the 3D image data respectively in the predetermined direction,
- causing the left image display to display the expanded image data for the left eye, and
- causing the right image display to display the expanded image data for the right eye.
