Abstract
A near-eye light-field display apparatus is provided, which includes a display module, a first lens module, an aperture device, and a second lens module. The display module displays light-field data. The first lens module collimates light rays emitted from the display module. The aperture device generates a plurality of coded apertures. The collimated light rays are modulated by the coded apertures. The second lens module focuses the modulated light rays on an image plane to form a real image.
Claims15
A near-eye light-field display apparatus, comprising:
- a display module, configured to display light-field data, wherein the light-field data comprises a plurality of first images that are displayed in a predetermined order;
- a first lens module, configured to collimate light rays emitted from the display module;
- an aperture device, configured to generate a plurality of coded apertures wherein the collimated light rays are modulated by the coded apertures;
- a second lens module, configured to focus the modulated light rays on an image plane to form a real image;
- a control circuit, controlling the display module and the aperture device,
- wherein in response to the first images being sub-view images of a light field, the control circuit performs a light-field encoding network to transform the sub-view images of the light field into coded sub-view images to be displayed on the display module.
A method for displaying a light field, for use in a near-eye light-field display apparatus, wherein the near-eye light-field display apparatus comprises a display module, a first lens module, an aperture device, and a second lens module, the method comprising:
- utilizing the display module to display light-field data, wherein the light-field data comprises a plurality of first images that are displayed in a predetermined order, wherein the first images are sub-view images of the light field or coded sub-view images of a coded light field;
- utilizing the first lens module to collimate light rays emitted from the display module;
- controlling the aperture device to generate a plurality of coded apertures, wherein the collimated light rays are modulated by the coded apertures;
- and
- utilizing the second lens module to focus the modulated light rays on an image plane to form a real image;
- in response to the first images being sub-view images of a light field, performing a light-field encoding network to transform the sub-view images of the light field into the coded sub-view images to be displayed on the display module.
