Abstract
A plurality of pixels is arrayed on a display device. On the display device, a lenticular lens is arranged in a state where a periodic direction thereof is inclined with respect to a horizontal direction. The lenticular lens divides video data of N different viewpoints into separate viewpoint directions, presents the divided video data, and creates stereoscopic vision. In the event of assigning respective pieces of pixel data of video data composed of less than N viewpoint images to the plurality of pixels and displaying the pixel data, the drive unit lowers brightness of pixel data of viewpoint images seen to overlap each other.
Claims9
A naked-eye stereoscopic display apparatus comprising:
- a display device in which a plurality of pixels are arrayed in a horizontal direction and a vertical direction;
- an optical member in which a plurality of optical elements are periodically arrayed and arranged on the display device in a state where the periodic direction of the optical elements is inclined with respect to the horizontal direction of the pixels in the display device and whereby, in the event of displaying first image data composed of N different viewpoint images where N is defined as an integer of three or more, the optical member is configured to divide the viewpoint images into each separate viewpoint direction and to present the divided viewpoint images on the display device, by assigning respective pieces of pixel data of the first image data to the plurality of pixels;
- and
- a brightness control unit which, in a state where second video data composed of less than N different viewpoint images is displayed on the display device by assigning respective pieces of pixel data of the second video data to the plurality of pixels, and where an observer observes the display device from the optical member side, is configured to lower brightness of pixel data of viewpoint images which are seen to overlap each other.
