Abstract

A method to prevent glare includes: detecting a glare with respect to a transparent display; identifying a light source corresponding to the glare; and setting a penetration level of a target region corresponding to a shape of the light source in the transparent display.

Claims

1. A method to prevent glare, the method comprising:

detecting a glare with respect to a transparent display;

identifying a light source corresponding to the glare; and

setting a penetration level of a target region corresponding to a shape of the light source in the transparent display.

2. The method of claim 1, wherein

the identifying of the light source comprises determining light source information of the light source, and

the setting of the penetration level of the target region comprises determining whether to adjust the penetration level of the target region based on the light source information.

3. The method of claim 1, wherein the setting of the penetration level of the target region comprises excluding a change of the penetration level of the target region, in response to a property of the light source corresponding to a penetration permission property.

4. The method of claim 1, wherein the setting of the penetration level of the target region comprises changing the penetration level of the target region, in response to a property of the light source corresponding to a penetration restriction property.

5. The method of claim 1, wherein the setting of the penetration level of the target region comprises reducing the penetration level of the target region to a restricted level, in response to a property of the light source corresponding to a penetration restriction property.

6. The method of claim 1, further comprising:

tracking a gaze of a user,

wherein the identifying of the light source comprises determining a region including a point at which light projected from the light source toward the transparent display intersects the gaze on the transparent display to be the target region.

7. The method of claim 1, wherein the detecting of the glare comprises

monitoring a luminance with respect to a front side of the transparent display;

and

detecting an occurrence of the glare in response to the monitored luminance exceeding a threshold luminance.

8. The method of claim 1, further comprising:

generating an ambient space map indicating distances from an apparatus comprising the transparent display to objects positioned in front of the transparent display.

9. The method of claim 1, wherein the setting of the penetration level of the target region comprises adjusting the penetration level of the target region, in response to a distance between the light source and an apparatus comprising the transparent display being less than a threshold distance.

10. The method of claim 1, further comprising:

generating a luminance map by monitoring a luminance with respect to a front side of the transparent display;

generating an ambient space map with respect to the front side of the transparent display; and

mapping the luminance map and the ambient space map,

wherein the identifying of the light source comprises

determining a light source region corresponding to a glare point in the ambient space map in response to the glare point being detected from the luminance map, the glare point having a luminance exceeding a threshold luminance, and

determining the target region based on the light source region.

11. A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 1.

12. An apparatus to prevent glare, the apparatus comprising:

a sensor configured to detect a glare with respect to a transparent display; and

a processor configured to identify a light source corresponding to the glare, and to set a penetration level of a target region corresponding to a shape of the light source in the transparent display.

13. The apparatus of claim 12, wherein the processor is configured to determine light source information of the light source, and to determine whether to adjust the penetration level of the target region based on the light source information.

14. The apparatus of claim 12, wherein the processor is further configured to exclude a change of the penetration level of the target region, in response to a property of the light source corresponding to a penetration permission property.

15. The apparatus of claim 12, wherein the processor is further configured to change the penetration level of the target region, in response to a property of the light source corresponding to a penetration restriction property.

16. The apparatus of claim 12, wherein the processor is further configured to reduce a penetration level of the target region, in response to a property of the light source corresponding to a penetration restriction property.

17. The apparatus of claim 12, wherein

the sensor comprises a gaze tracker configured to track a gaze of a user, and

the processor is further configured to determine a region comprising a point at which light projected from the light source toward the transparent display intersects the gaze on the transparent display to be the target region.

18. The apparatus of claim 12, wherein

the sensor comprises a luminance sensor configured to monitor a luminance with respect to a front side of the transparent display, and

the processor is further configured to detect an occurrence of the glare in response to the monitored luminance exceeding a threshold luminance.

19. The apparatus of claim 12, wherein

the sensor comprises an ambient space sensor configured to generate an ambient space map indicating distances from the apparatus to objects positioned in front of the transparent display, and

the processor is further configured to adjust the penetration level of the target region, in response to a distance between the light source and the apparatus being less than a threshold distance.

20. The apparatus of claim 12, wherein

the sensor comprises a luminance sensor configured to generate a luminance map by monitoring a luminance with respect to a front side of the transparent display, and an ambient space sensor configured to generate an ambient space map with respect to the front side of the transparent display, and

the processor is further configured to determine a light source region corresponding to a glare point in the ambient space map, in response to the glare point being detected from the luminance map, the glare point having a luminance exceeding a threshold luminance, and to determine a target region of the transparent display based on the light source region.
