Abstract
A display device includes a display device body. The display device body includes a first lens barrel and a second lens barrel. A first lens is disposed at a first end of the first lens barrel, and a second lens is disposed at a first end of the second lens barrel. A first distance sensor and a second distance sensor are further disposed on the display device body. The second distance sensor is configured to measure a distance between a right eyeball and the second lens. Two distance sensors are disposed on the display device body.

A display device, comprising:
- a display device body, comprising:
- a first lens barrel, comprising:
- a first end;
- a first lens coupled to the first end;
- and
- a first edge region;
- a second lens barrel, comprising:
- a second end;
- a second lens coupled to the second end;
- and
- a second edge region;
- a longitudinal central axis comprising:
- a first side;
- and
- a second side;
- a first distance sensor symmetrically disposed on the first side and configured to measure a first distance between a left eyeball and the first lens, wherein the first distance sensor is disposed in the first edge region;
- a second distance sensor symmetrically disposed on the second side and configured to measure a second distance between a right eyeball and the second lens, wherein the second distance sensor is disposed in the second edge region;
- and
- a traverse central axis, wherein the first edge region comprises a first intersecting point along the traverse central axis that is close to the longitudinal central axis and a second intersecting point along the traverse central axis, wherein the second edge region comprises a third intersecting point along the traverse central axis that is close to the longitudinal axis and a fourth intersecting point along the traverse central axis, wherein the first distance sensor is disposed at the first intersecting point, and wherein the second distance sensor is disposed at the third intersecting point.
A method for adjusting image presence on a display device comprising:
- obtaining a first image comprising a left eyeball image of a user;
- obtaining a second image comprising a right eyeball image of the user;
- obtaining a first distance between a first lens and the left eyeball of the user, wherein the first lens is closer to the left eyeball of the user than a second lens;
- obtaining a second distance between the second lens and the right eyeball of the user, wherein the second lens is closer to the right eyeball of the user than the first lens;
- normalizing the first image based on the first distance and the second distance;
- normalizing the second image based on the first distance and the second distance;
- calculating an interpupillary distance between the left eyeball and the right eyeball based on a normalized first image and a normalized second image;
- adjusting the first lens or the second lens based on the interpupillary distance of the user;
- obtaining a pupil image with a preset size, wherein a preset reference distance is either between the first lens and the left eyeball of the user, or between the second lens and the right eyeball of the user;
- calculating a ratio of the first distance to the preset reference distance to obtain a first scaling coefficient;
- calculating a ratio of the second distance to the preset reference distance to obtain a second scaling coefficient;
- scaling the first image using the first scaling coefficient;
- and
- scaling the second image using the second scaling coefficient.
A computer program product comprising computer-executable instructions stored on a non-transitory computer-readable medium that, when executed by a processor, cause a display device to:
- obtain a first image comprising a left eyeball image of a user;
- obtain a second image comprising a right eyeball image of the user;
- obtain a first distance between a first lens and the left eyeball of the user, wherein the first lens is closest to the left eyeball of the user;
- obtain a second distance between a second lens and the right eyeball of the user, wherein the second lens is closest to the right eyeball of the user in all the lenses of the display device;
- normalize the first image based on the first distance and the second distance;
- normalize the second image based on the first distance and the second distance;
- calculate an interpupillary distance between the left eyeball and the right eyeball based on a normalized first image and a normalized second image;
- adjust the first lens or the second lens based on the interpupillary distance of the user;
- calculate a ratio of the first distance to a preset reference distance to obtain a first scaling coefficient;
- obtain a pupil image with a preset size, wherein the preset reference distance is either between the first lens and the left eyeball of the user, or between the second lens and the right eyeball of the user;
- calculate a ratio of the second distance to the preset reference distance to obtain a second scaling coefficient;
- scale the first image using the first scaling coefficient;
- and
- scale the second image using the second scaling coefficient.
