Abstract

Provided is a display control device including an operation display unit for detecting operation positions, on a display screen, in accordance with a user operation on the display screen, a state determination unit for determining, based on a detection result of the operation positions, a first operation state where two operation positions are detected, a process determination unit for determining, based on a change in the operation positions in the first operation state, a process related to display that is to be performed, and a display control unit for performing, based on a determination result of a process, a process which has been determined to be performed, and causing the display screen to perform display corresponding to the process. The display control unit continues the display corresponding to the process which has been determined to be performed, according to a duration of determination for the process which has been determined.

Claims

1. A display control device comprising:

an operation display unit for displaying a display screen, and detecting one or more operation positions, on the display screen, in accordance with a user operation on the display screen;

a state determination unit for determining, based on a detection result of the operation positions, a first operation state where two operation positions are detected;

a process determination unit for determining, based on a change in the operation positions in the first operation state, a process related to display that is to be performed; and

a display control unit for performing, based on a determination result of a process, a process which has been determined to be performed, and causing the display screen to perform display corresponding to the process,

wherein the display control unit continues the display corresponding to the process which has been determined to be performed, according to a duration of determination for the process which has been determined.

2. The display control device according to claim 1, wherein, in a case the process which has been determined is a process of changing display by enlarging or reducing a time axis where a display screen on which a list of images arranged on the time axis is displayed is being displayed, the display control unit changes the display by enlarging or reducing the time axis according to the duration of determination.

3. The display control device according to claim 2, wherein the display screen on which the list of images arranged on the time axis is displayed is a display screen on which the time axis is shown in a spiral manner.

4. The display control device according to claim 1, wherein, in a case the process which has been determined is a process of increasing or reducing a display size of display content displayed on the display screen, the display control unit increases or reduces the display size of display content according to the duration of determination.

5. The display control device according to claim 1,

wherein the process determination unit

calculates an area change speed that is based on a distance between two operation positions that are detected and an area change amount, indicating an amount of change in display, that is based on the area change speed,

determines a type of the process to be performed based on the area change speed which has been calculated, and

decides the amount of change in display based on the area change amount which has been calculated.

6. The display control device according to claim 5,

wherein the process determination unit

further calculates a product of a previously calculated area change speed and a currently calculated area change speed, and

determines, in a case a value of the product which has been calculated is a negative value, that a repetitive operation has been performed, and determines a process corresponding to the repetitive operation as the process to be performed.

7. The display control device according to claim 6, wherein the process determination unit further determines a type of the process corresponding to the repetitive operation based on the currently calculated area change speed.

8. The display control device according to claim 5,

wherein the state determination unit further determines, based on the detection result of the operation positions, a change from the first operation state to a second operation state where the operation positions are not detected,

wherein the process determination unit calculates an integrated value of the calculated area change amount,

wherein, in a case the process determination unit calculates the integrated value, the display control unit

does not perform the process which has been determined to be performed, until the state determination unit determines that the change to the second operation state has taken place,

causes the display screen to display a process result candidate indicating a process result which will be obtained when the process is performed according to the integrated value, and

causes the display screen to perform display corresponding to the process result candidate, when the change to the second operation state is determined to have taken place.

9. The display control device according to claim 8, wherein the display control unit causes the process result candidate to be displayed in a pop-up window.

10. The display control device according to claim 9, wherein the display control unit causes display content which will be obtained when the process is performed according to the integrated value to be displayed as the process result candidate.

11. The display control device according to claim 9, wherein the display control unit causes text information corresponding to display content which will be obtained when the process is performed according to the integrated value to be displayed as the process result candidate.

12. The display control device according to claim 1,

wherein the state determination unit further determines, based on the detection result of the operation positions, a change from the first operation state to a third operation state where one or three or more operation positions are detected, and

wherein, when the change to the third operation state is determined to have taken place, the display control unit temporarily suspends execution of a process that is being performed or causes display content before execution of the process that is being performed to be display content of the display screen.

13. The display control device according to claim 12,

wherein the state determination unit further determines, based on the detection result of the operation positions, a change from the third operation state to the first operation state, and

wherein the display control unit restarts, when the change to the first operation state is determined to have taken place, execution of the process that is temporarily suspended.

14. A display control method comprising:

determining, based on a detection result, at an operation display unit for displaying a display screen and detecting one or more operation positions on the display screen in accordance with a user operation on the display screen, of the operation positions, a first operation state where two operation positions are detected;

determining, based a change in the operation positions in the first operation state, a process related to display that is to be performed; and

performing, based on a determination result of a process, a process which has been determined to be performed, and causing the display screen to perform display corresponding to the process,

wherein, in the step of causing the display screen to perform display, the display corresponding to the process which has been determined to be performed is continued according to a duration of determination for the process which has been determined.

15. A program for causing a computer to perform:

determining, based on a detection result, at an operation display unit for displaying a display screen and detecting one or more operation positions on the display screen in accordance with a user operation on the display screen, of the operation positions, a first operation state where two operation positions are detected;

determining, based a change in the operation positions in the first operation state, a process related to display that is to be performed; and

performing, based on a determination result of a process, a process which has been determined to be performed, and causing the display screen to perform display corresponding to the process,

wherein, in the step of causing the display screen to perform display, the display corresponding to the process which has been determined to be performed is continued according to a duration of determination for the process which has been determined.
