Display device and display method
View Patent ↗Provided are a display device, and a display method which improve operability of a proximity operation and a contact operation by using an interface display such as a magnification adjustment-use interface. Provided is a display unit that includes a control unit, a storage unit, a display unit, a display processing unit, a sensor unit, a coordinate acquisition unit, a reference position determining unit, and a defined region determining unit. A user approximates an instruction medium to the display unit and closely holds the instruction medium, for example, in a portion to be enlarged on a map displayed on the display unit. The display processing unit which received detection signals by the sensor unit displays an interface in which enlargement is performed on the map in a proximity of an instruction medium based on the obtained position coordinates.

a reference position determining unit configured to determine whether or not the instruction medium detected by the sensor unit is in a predetermined position on the display unit, in a close state in which the instruction medium is distant within a predetermined distance from the display unit for a predetermined time period or more, and determine the predetermined position as a reference position of a zoom display in a case where the instruction medium is determined to be in the close state; and
a display processing unit configured to display a magnification adjustment-use interface on the display unit at the time of determining the reference position.
2. The display device according to claim 1 ,
wherein the display processing unit changes a display mode of the magnification adjustment-use interface depending on a distance between the instruction medium and the magnification adjustment-use interface.
3. The display device according to claim 1 , further comprising:
a defined region determining unit configured to determine, as a defined region, a predetermined range including the reference position and defined in a parallel direction with respect to the display unit at the time of determining the reference position,
wherein an operation of the magnification adjustment-use interface is disabled in a case where the instruction medium is moved to an outside of the defined region with the close state kept.
4. The display device according to claim 3 ,
wherein the operation of the magnification adjustment-use interface is disabled after a predetermined time period elapses from when the instruction medium is moved to an outside of the defined region.
5. The display device according to claim 1 ,
wherein the operation of the magnification adjustment-use interface is disabled in a case where the instruction medium is deviated from the magnification adjustment-use interface after the instruction medium performs an operation of the magnification adjustment-use interface.
6. The display device according to claim 5 , wherein the operation of the magnification adjustment-use interface by the instruction medium does not exceed a predetermined range.
7. The display device according to claim 1 , wherein a change amount of the magnification is set to be small immediately after the operation of the magnification adjustment-use interface by the instruction medium, and the change amount of the magnification is increased in accordance with duration of the operation.
8. The display device according to claim 7 , wherein in a case where an operation of the magnification adjustment-use interface by the instruction medium in an opposite direction to a direction in which the operation of the magnification adjustment-use interface is performed, the change amount of the magnification is set to be constant.
9. A portable terminal device comprising:
the display device according to claim 1 .
10. A display device comprising:
a display unit configured to display an image;
a sensor unit configured to detect an instruction medium which is approximated to the display unit;
a reference position determining unit configured to determine whether or not the instruction medium detected by the sensor unit is in a predetermined position on the display unit, in a close state in which the instruction medium is distant within a predetermined distance from the display unit for a predetermined time period or more, and determine the predetermined position as a reference position of a specific operation to the display unit in a case where the instruction medium is determined to be in the close state;
a display processing unit configured to display a predetermined interface regarding the specific operation on the display unit at the time of determining the reference position; and
a defined region determining unit configured to determine, as a defined region, a predetermined range including the reference position and defined in a parallel direction with respect to the display unit at the time of determining the reference position,
wherein an operation of the predetermined interface is disabled in a case where the instruction medium is moved to an outside of the defined region.
11. The display device according to claim 10 ,
wherein the operation of the predetermined interface is disabled after a predetermined time period elapses from when the instruction medium is moved to an outside of the defined region.
12. A portable terminal device comprising:
the display device according to claim 10 .
13. A display method comprising:
a step of displaying an image on a display unit;
a step of detecting an instruction medium which is approximated to the display unit by a sensor unit;
a step of determining whether or not the instruction medium is in a predetermined position on the display unit, in a close state in which the instruction medium is distant within a predetermined distance from the display unit for a predetermined time period or more and determining the predetermined position as a reference position of a zoom display in a case where the instruction medium is determined to be in the close state; and
a step of displaying a magnification adjustment-use interface on the display unit at the time of determining the reference position.
14. A display method comprising:
a step of displaying an image on a display unit;
a step of detecting an instruction medium which is approximated to the display unit by a sensor unit;
a step of determining whether or not the instruction medium detected by the sensor unit is in a predetermined position on the display unit, in a close state in which the instruction medium is distant within a predetermined distance from the display unit for a predetermined time period or more determining the predetermined position as a reference position of a specific operation to the display unit in a case where the instruction medium is determined to be in the close state;
a step of displaying a predetermined interface regarding the specific operation on the display unit at the time of determining the reference position;
a step of determining, as a defined region, a predetermined range including the reference position and defined in a parallel direction with respect to the display unit at the time of determining the reference position; and
a step of disabling an operation of the predetermined interface in a case where the instruction medium is moved to an outside of the defined region.
