Abstract

A display device includes: a display unit displaying an image on a display surface; a detection unit detecting a position of a pointing unit on the display surface; and a control unit causing the display unit to display an image based on the position detected by the detection unit. The control unit causes the display unit to display a first image group including a plurality of sample images having different settings of a first attribute from each other and a same setting of a second attribute that is different from the first attribute, the first image group being scrollable in a first direction, and a second image group including a plurality of sample images having a same setting of the first attribute and different settings of the second attribute from each other, the second image group being scrollable in a second direction that is different from the first direction.

Claims

1. A display device comprising:

a display unit displaying an image on a display surface;

a detection unit detecting a position of a pointing unit on the display surface; and

a control unit causing the display unit to display an image based on the position detected by the detection unit,

wherein

the control unit

causes the display unit to display a first image group including a plurality of sample images having different settings of a first attribute from each other and a same setting of a second attribute that is different from the first attribute, the first image group being scrollable in a first direction, and a second image group including a plurality of sample images having a same setting of the first attribute and different settings of the second attribute from each other, the second image group being scrollable in a second direction that is different from the first direction, and

decides a setting of the first attribute and the second attribute used for the image based on the position detected by the detection unit, according to selection of a sample image included in the first image group or the second image group.

2. The display device according to claim 1, wherein

the first image group and the second image group include a same sample image in an area where the first image group and the second image group overlap each other.

3. The display device according to claim 1, wherein

the first direction is a direction along a first straight line, and

the second direction is a direction along a second straight line intersecting the first straight line.

4. The display device according to claim 1, wherein

the control unit

causes the display unit to display a third image group including a plurality of sample images having different settings from each other of a third attribute that is different from the first attribute and the second attribute and a same setting of the first attribute and the second attribute, the third image group being scrollable in a third direction that is different from the first direction and the second direction, and

decides a setting of the first attribute, the second attribute, and the third attribute used for the image based on the position detected by the detection unit, according to selection of a sample image included in the first image group, the second image group, or the third image group.

5. The display device according to claim 1, wherein

the control unit can change a position of an area where the first image group and the second image group overlap each other.

6. The display device according to claim 1, wherein

the first direction is a direction along a first circumference, and

the second direction is a direction along a second circumference intersecting the first circumference.

7. The display device according to claim 1, wherein

the control unit changes the setting of the first attribute of the second image group according to scrolling of the first image group or changes the setting of the second attribute of the first image group according to scrolling of the second image group.

8. The display device according to claim 1, wherein

the control unit can change one or both of the first attribute and the second attribute.

9. The display device according to claim 1, wherein

the first attribute or the second attribute is color, thickness, or line type.

10. The display device according to claim 9, wherein

the first attribute is color, and

the second attribute is thickness.

11. The display device according to claim 9, wherein

the first attribute is shape, and

the second attribute is color, thickness, or line type.

12. The display device according to claim 1, wherein

the control unit causes the display unit to display the first image group and the second image group as superimposed on an image based on image information from an external device.

13. The display device according to claim 1, further comprising

a storage unit storing information about an attribute history of the image based on the position detected by the detection unit, wherein

the control unit decides a setting of the first attribute or the second attribute used for the first image group or the second image group, based on the information.

14. A display method comprising:

displaying, on a display surface, a first image group including a plurality of sample images having different settings of a first attribute from each other and a same setting of a second attribute that is different from the first attribute, the first image group being scrollable in a first direction, and a second image group including a plurality of sample images having a same setting of the first attribute and different settings of the second attribute from each other, the second image group being scrollable in a second direction that is different from the first direction;

causing one sample image included in the first image group or the second image group to be selected;

deciding the first attribute and the second attribute according to the selection of the one sample image;

detecting a position of a pointing unit on the display surface; and

displaying, on the display surface, an image having the first attribute and the second attribute that are decided, based on the detected position.

15. A display system comprising:

a display unit displaying an image on a display surface;

a detection unit detecting a position of a pointing unit on the display surface; and

a control unit causing the display unit to display an image based on the position detected by the detection unit, wherein

the control unit causes the display unit to display a first image group including a plurality of sample images having different settings of a first attribute from each other and a same setting of a second attribute that is different from the first attribute, the first image group being scrollable in a first direction, and a second image group including a plurality of sample images having a same setting of the first attribute and different settings of the second attribute from each other, the second image group being scrollable in a second direction that is different from the first direction, and

decides a setting of the first attribute and the second attribute used for the image based on the position detected by the detection unit, according to selection of a sample image included in the first image group or the second image group.
