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:

a circuit configured to;

determine a first operation state based on a result of detecting one or more operation positions as first operation positions by a user;

determine, based on a change from the first operation positions to second operation positions, a process related to display that is to be performed;

cause a display screen to perform display corresponding to the process; and

continue the display corresponding to the process which has been determined to be performed, according to a duration of holding in the second operation positions,

wherein, in a case the process which has been determined is a process of changing the display by enlarging or reducing a time axis where the display screen on which a list of images arranged on the time axis is displayed is being displayed, the circuit changes the display by enlarging or reducing the time axis according to the duration of determination,

wherein the circuit causes the time axis to be displayed in a spiral manner so as to form a spiral time axis on the display screen on which the list of images are horizontally and vertically arranged, in which said spiral time axis provides a first time interval between adjacent images which are horizontally arranged and provides a second time interval between adjacent images which are vertically arranged, and in which said first time interval is different from said second time interval.

2. A display control device comprising:

a circuit configured to;

determine a first operation state based on a result of detecting one or more operation positions as first operation positions by a user;

determine, based on a change from the first operation positions to second operation positions, a process related to display that is to be performed;

cause a display screen to perform display corresponding to the process; and

continue the display corresponding to the process which has been determined to be performed, according to a duration of holding in the second operation positions,

wherein the circuit causes a time axis to be displayed in a spiral manner so as to form a spiral time axis on the display screen,

wherein a list of images are horizontally and vertically arranged on the spiral time axis,

wherein the spiral time axis provides a first time interval between adjacent images which are horizontally arranged and provides a second time interval between adjacent images which are vertically arranged, and in which the first time interval is different from the second time interval, and

wherein the circuit is further configured to;

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

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

decide the amount of change in the display based on the area change amount which has been calculated,

wherein the circuit further determines, based on the detection result of the one or more operation positions, a change from the first operation state to a second operation state where the one or more operation positions are not detected,

wherein the circuit calculates an integrated value of the calculated area change amount,

wherein, in a case the circuit calculates the integrated value, the circuit;

does not perform the process which has been determined to be performed, until the circuit 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.

3. The display control device according to claim 2, wherein the circuit causes the process result candidate to be displayed in a pop-up window.

4. The display control device according to claim 2, wherein the circuit 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.

5. The display control device according to claim 2, wherein the circuit 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.

6. A display control method comprising:

determining a first operation state based on a result of detecting one or more operation positions as first operation positions by a user;

determining, based on a change from the first operation positions to second operation positions, a process related to display that is to be performed;

causing a display screen to perform display corresponding to the process, and

continuing the display corresponding to the process which has been determined to be performed, according to a duration of holding in the second operation positions,

wherein, in a case the process which has been determined is a process of changing the display by enlarging or reducing a time axis where the display screen on which a list of images arranged on the time axis is displayed is being displayed, the display is changed by enlarging or reducing the time axis according to the duration of determination,

wherein the time axis is caused to be displayed in a spiral manner so as to form a spiral time axis on the display screen on which the list of images are horizontally and vertically arranged, in which said spiral time axis provides a first time interval between adjacent images which are horizontally arranged and provides a second time interval between adjacent images which are vertically arranged, and in which said first time interval is different from said second time interval.

7. A non-transitory computer readable storage medium having stored thereon a program for causing a computer to perform:

determining a first operation state based on a result of detecting one or more operation positions as first operation positions by a user;

determining, based on a change from the first operation positions to second operation positions, a process related to display that is to be performed;

causing a display screen to perform display corresponding to the process, and

continuing the display corresponding to the process which has been determined to be performed, according to a duration of holding in the second operation positions,

wherein, in a case the process which has been determined is a process of changing the display by enlarging or reducing a time axis where the display screen on which a list of images arranged on the time axis is displayed is being displayed, the display is changed by enlarging or reducing the time axis according to the duration of determination,

wherein the time axis is caused to be displayed in a spiral manner so as to form a spiral time axis on the display screen on which the list of images are horizontally and vertically arranged, in which said spiral time axis provides a first time interval between adjacent images which are horizontally arranged and provides a second time interval between adjacent images which are vertically arranged, and in which said first time interval is different from said second time interval.
