Abstract

[Object] To provide a control device, control method, and program, capable of improving the operability of a touch operation while eliminating or reducing the erroneous detection of the touch operation. [Solution] A control device including: a determination unit configured to determine whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area.

Claims

1. A control device comprising:

a determination unit configured to determine whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area.

2. The control device according to claim 1,

wherein the determination unit, in a case where the start point of the touch-and-movement operation is located within the valid area, determines that the touch-and-movement operation is valid.

3. The control device according to claim 1,

wherein the determination unit, in a case where the start point of the touch-and-movement operation is located within the invalid area, determines that the touch-and-movement operation is invalid.

4. The control device according to claim 1,

wherein the determination unit, in a case where the start point of the touch-and-movement operation is located within the invalid area, determines that only an operation after movement of a touch position from the invalid area to the valid area among the touch-and-movement operations is valid.

5. The control device according to claim 1,

wherein the invalid area is divided into a first invalid area that is adjacent to the valid area and a second invalid area that is not adjacent to the valid area,

the determination unit, in a case where the start point of the touch-and-movement operation is located within the second invalid area, determines that the touch-and-movement operation is invalid, and

the determination unit, in a case where the start point of the touch-and-movement operation is located within the first invalid area, the determination unit determines that only an operation after movement of a touch position from the first invalid area to the valid area among the touch-and-movement operations is valid.

6. The control device according to claim 1, further comprising:

an area setting unit configured to set the valid area and the invalid area on the display unit on a basis of presence or absence of detection of proximity of an eye to a finder.

7. The control device according to claim 6,

wherein the area setting unit, in a case where the proximity of the eye to the finder is detected, sets a predetermined area on the display unit as the valid area and sets an area other than the predetermined area on the display unit as the invalid area.

8. The control device according to claim 6,

wherein the area setting unit, in a case where the proximity of the eye to the finder is not detected, sets an entire area of the display unit as the valid area.

9. The control device according to claim 1,

wherein the touch-and-movement operation is a drag operation on the display unit.

10. The control device according to claim 1,

wherein the touch-and-movement operation is an operation used to specify a position to be focused.

11. The control device according to claim 1, further comprising:

an operation position specifying unit configured to specify an operation position corresponding to a touch position being moved by the touch-and-movement operation on a basis of presence or absence of detection of proximity of an eye to a finder.

12. The control device according to claim 11,

wherein the operation position specifying unit, in a case where the proximity of the eye to the finder is detected, specifies the touch position being moved as the operation position.

13. The control device according to claim 11,

wherein the operation position specifying unit, in a case where the proximity of the eye to the finder is not detected, specifies the operation position on a basis of an operation position corresponding to the start point of the touch-and-movement operation and a positional relationship between the start point of the touch-and-movement operation and the touch position being moved.

14. The control device according to claim 11,

wherein the operation position specifying unit, in a case where the presence or absence of the detection of the proximity of the eye to the finder is changed, determines a touch position when the presence or absence of the detection of the proximity of the eye to the finder is changed as an end point of the touch-and-movement operation.

15. The control device according to claim 1, further comprising:

a processing control unit configured to execute processing regarding photographing or image reproduction, in a case where the touch-and-movement operation is determined as valid by the determination unit, on a basis of the touch-and-movement operation.

16. The control device according to claim 15,

wherein the processing control unit moves a display position of an operation target of the touch-and-movement operation that is displayed on a finder or the display unit on the basis of the touch-and-movement operation.

17. The control device according to claim 16,

wherein the processing control unit changes a moving speed of the operation target of the touch-and-movement operation further on a basis of presence or absence of detection of proximity of an eye to the finder.

18. The control device according to claim 15,

wherein the processing control unit causes a to be displayed on a finder or the display unit, the display indicating that validity of a touch operation on the display unit is changed further depending on whether an eye approaches the finder.

19. A control method comprising:

determining whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area.

20. A program causing a computer to function as:

a determination unit configured to determine whether a touch-and-movement operation is valid across a valid area in which a touch operation on a display unit is treated as valid and an invalid area in which the touch operation is treated as invalid on a basis of whether a start point of the touch-and-movement operation is located within the valid area.
