Abstract

A transparent display apparatus is provided. The transparent display apparatus includes a transparent display which displays information, a sensor which senses background information in a first direction, and a controller configured to modify a display state of the displayed information on the transparent display based on the sensed background information.

First claim

What is claimed is:

1. A display apparatus, comprising:
a projector;
a sensor configured to sense a position and color information of an object located in a direction from a transparent screen; and
at least one processor configured to control the projector to project information on the transparent screen in a color different from a color of the object based on the color information of the object if the information is projected on an area of the transparent screen, where the object is viewed through the transparent screen.

2. The display apparatus of claim 1 ,
wherein the sensor further comprises an illumination intensity sensor configured to sense illumination intensity in the direction, and
wherein the at least one processor is further configured to adjust at least one of brightness values and color values of pixel areas corresponding to the projected information based on the sensed illumination intensity state.

3. The display apparatus of claim 2 , wherein the direction is behind the display apparatus with respect to a user.

4. The display apparatus of claim 1 ,
wherein the sensor comprises a photographing sensor configured to photograph an object located in the direction, and
wherein the at least one processor is further configured to adjust at least one of brightness values and color values of pixel areas corresponding to the projected information based on color information of the object.

5. The display apparatus of claim 1 , wherein the at least one processor is further configured to:
estimate an area where the object is observed on the transparent screen based on the sensed object position and a user position, and
adjust at least one of brightness values and color values of pixel areas corresponding to the projected information on the estimated area.

6. The display apparatus of claim 5 , wherein the at least one processor is further configured to:
estimate an area where the moved object is observed from the user position when the sensed object position is changed, and
adjust at least one of brightness values and color values of pixel areas corresponding to the projected information on the estimated area.

7. The display apparatus of claim 1 ,
wherein the sensor comprises a photographing sensor configured to photograph an object located in the direction, and
wherein the at least one processor is further configured to control the projector to project the information on the transparent screen in a position different from a position of the object viewed through the transparent screen based on color information of the object in the photographed image.

8. The display apparatus of claim 1 , wherein the transparent screen is included in the display apparatus.

9. A method of controlling a display apparatus, the method comprising:
sensing a position and color information of an object located in a direction from a transparent screen; and
projecting information on the transparent screen,
wherein the projecting of the information comprises projecting the information on the transparent screen in a color different from a color of the object based on the color information of the object if the information is projected on an area of the transparent screen, where the object is viewed through the transparent screen.

10. The method of claim 9 ,
wherein the sensing of the position and color information of the object comprises sensing illumination intensity in the direction, and
wherein the projecting of the information comprises adjusting at least one of brightness values and color values of pixel areas corresponding to the projected information based on the sensed illumination intensity state.

11. The method of claim 10 , wherein the direction is behind the display apparatus with respect to a user.

12. The method of claim 9 ,
wherein the sensing of the position and color information of the object comprises photographing the object located in the direction, and
wherein the projecting of the information comprises adjusting at least one of brightness values and color values of pixel areas corresponding to the projected information based on color information of the object in a photographed image.

13. The method of claim 12 , wherein the projecting of the information includes:
estimating an area where the object is observed on the transparent screen based on the sensed object position and a user position; and
adjusting and projecting at least one of brightness values and color values of pixel areas corresponding to the projected information on the estimated area.

14. The method of claim 13 , further comprising:
estimating an area where the moved object is observed from the user position when the sensed object position is changed; and
adjusting at least one of brightness values and color values of pixel areas corresponding to the projected information on the estimated area.

15. The method of claim 9 ,
wherein the sensing of the position and color information of the object comprises photographing an object located in the direction, and
wherein the projecting of the information includes modifying a projection position of the projected information based on color information of the object in a photographed image.

16. A non-transitory computer-readable storage medium storing instructions that, when executed, cause at least one processor to perform the method of claim 9 .

17. A display apparatus, comprising:
a display;
a photographing sensor configured to photograph an object located in a direction; and
at least one processor configured to control the display to display information on the display in a color different from a color of the object included in an image photographed by the photographing sensor based on color information of the object, if the information is displayed on an area of the display, where the object is located on the image.
