Method of adapting 3D content to an observer wearing prescription glasses
View Patent ↗The invention consists in a method of and a device for adapting 3D content to an observer wearing prescription glasses. The method comprises the step of—providing information about prescription glasses of the observer;—calculating a value representative of the optical deviation created by the glasses from the provided information, for a given direction;—estimating a depth adjustment value as a function of the calculated value and—modifying the depth of the 3D content according to the estimated depth adjustment value.
1. A method of adapting 3D content to a viewer wearing prescription glasses while watching said 3D content,
wherein the method comprises:
modifying a depth of said 3D content according to an estimated depth adjustment value obtained from a variation of an angle formed by a direction of a viewer's visual axis to an eyeglass lens optical axis corresponding to a deviation created by the prescription glasses, and wherein the prescription glasses are defined by parameters e, r and f′, wherein e is a distance between a cornea to a prescription glasses lens, r is an eyeball radius, and f′ is a focal length of the prescription glasses.
2. The method of adapting 3D content as claimed in claim 1 wherein the deviation is calculated in angular degrees or in percentage.
3. The method of adapting 3D content as claimed in claim 1 wherein the depth adjustment value is estimated to compensate for the deviation.
4. The method of adapting 3D content as claimed in claim 1 wherein the depth adjustment value is estimated by a conversion matrix to compensate for the deviation.
5. The method of adapting 3D content as claimed in claim 1 wherein the prescription glasses intend to correct myopia of the viewer.
6. The method of adapting 3D content as claimed in claim 1 wherein the prescription glasses intend to correct hyperopia of the viewer.
7. The method of adapting 3D content as claimed in claim 1 wherein said focal length is deduced from an output of face analysis software for the viewer.
8. A device for adapting 3D content to a viewer wearing prescription glasses
wherein the device comprises:
a calculation unit configured to modify depth of said 3D content according to an estimated depth adjustment value obtained from a variation of an angle formed by a direction of a viewer's visual axis to an eyeglass lens optical axis corresponding to a deviation created by the prescription glasses, and wherein the prescription glasses are defined by parameters e, r and f′, wherein e is a distance between cornea to prescription glasses lens, r is the eyeball radius, and f′ is a focal length of the prescription glasses.
9. The device for adapting 3D content as claimed in claim 8 , wherein the deviation is calculated in angular degrees or in percentage.
10. The device for adapting 3D content as claimed in claim 8 , wherein the depth adjustment value is estimated to compensate for the deviation.
11. The device for adapting 3D content as claimed in claim 8 , wherein the depth adjustment value is estimated by a conversion matrix to compensate for the deviation.
12. The device for adapting 3D content as claimed in claim 8 , wherein the prescription glasses intend to correct myopia of the viewer.
13. The device for adapting 3D content as claimed in claim 8 , wherein the prescription glasses intend to correct hyperopia of the viewer.
14. The device for adapting 3D content as claimed in claim 8 , wherein said focal length is deduced from an output of face analysis software for the viewer.
