Abstract

A display input device includes: a display panel that displays an operation image; a touch panel portion that is used to detect the coordinates of a fingertip and the coordinates of an actual touch position in a close state in which the fingertip approaches the surface; and a control portion that recognizes an operation image operated by recognizing the touch position, that determines, based on the position of the fingertip in the close state and the track of the fingertip in the close state, whether or not in the close state, the fingertip is in a swing state in which the fingertip swings and that enlarges and displays, on the display panel, the operation image below the track when the fingertip is determined to be in the swing state.

Claims

1. A display input device comprising:

a display panel that displays an operation image for setting;

a touch panel portion that is provided above the display panel and that detects a coordinate of a fingertip in a close state in which a surface is not touched but the fingertip approaches the surface and a coordinate of an actual touch position; and

a control portion that recognizes a position of the fingertip in the close state and a track of the fingertip in the close state, determines, based on the recognized track, whether or not in the close state, the fingertip is in a swing state in which the fingertip swings and enlarges and displays, on the display panel, one or a plurality of the operation images displayed below the track when the fingertip is determined to be in the swing state;

wherein the control portion determines a swing range of the fingertip based on the track and enlarges and displays, on the display panel, the operation image such that a width of the operation image after being enlarged and displayed in an up/down direction is wider than a width of the swing range in the up/down direction and that a width of the operation image after being enlarged and displayed in a left/right direction is wider than a width of the swing range in the left/right direction,

wherein the swing state comprises a trembling or at least one switching of direction of movement.

2. The display input device according to claim 1,

wherein when a number of times a direction of movement of the fingertip is switched in the close state within a predetermined determination period is more than a predetermined reference number, the control portion determines that the fingertip is in the swing state.

3. The display input device according to claim 2,

wherein as the number of times the direction of the movement of the fingertip is switched is increased, the control portion increases an enlargement rate in the enlargement and display.

4. The display input device according to claim 3, further comprising:

a storage portion that stores switching number data in which the enlargement rate corresponding to the number of times the switching is performed is determined

wherein the switching number data is defined such that as the number of times the switching is performed is increased, the enlargement rate is increased, and

the control portion determines the enlargement rate based on the actually counted number of times the switching is performed and the switching number data.

5. The display input device according to claim 1,

wherein when the fingertip is determined to be in the swing state such that the operation image is enlarged and displayed, the control portion enlarges and displays, on the display panel, the operation image where a time during which the fingertip is thereabove within a predetermined period is the longest.

6. The display input device according to claim 5,

wherein the control portion enlarges and displays, on the display panel, the operation image adjacent to the operation image where the time during which the fingertip is thereabove within the predetermined period is the longest.

7. The display input device according to claim 1,

wherein when the fingertip is determined to be in the swing state such that the operation image is enlarged and displayed, the control portion enlarges and displays, on the display panel, a plurality of the operation images displayed below the track within a predetermined period.

8. The display input device according to claim 5,

wherein the control portion enlarges and displays, on the display panel, the operation images adjacent to the operation images displayed below the track within the predetermined period.

9. The display input device according to claim 1, further comprising:

a storage portion that stores enlargement rate adjustment data in which an adjustment value for a number of times a direction of movement of the fingertip is switched in the close state within a predetermined period is determined,

wherein in the enlargement rate adjustment data, as the number of times the switching is performed is increased, a higher adjustment value is defined and

the control portion adds the adjustment value obtained based on the enlargement rate adjustment data to a magnification determined based on the swing range so as to determine an enlargement rate which is applied to the enlargement and display.

10. The display input device according to claim 1,

wherein the control portion detects that the fingertip enters a separated state in which the fingertip is a longer distance away from a surface of the touch panel portion than a distance which is determined to be in the close state, and returns, when a predetermined cancellation time has elapsed since the separated state is entered, a display size of the operation image enlarged and displayed to a normal size.

11. The display input device according to claim 1,

wherein the touch panel portion includes a capacitive type sensor panel.

12. A method of controlling a display input device, the method comprising:

displaying an operation image for setting;

detecting a coordinate of a fingertip in a close state in which a surface is not touched but the fingertip approaches the surface and a coordinate of an actual touch position;

recognizing a position of the fingertip in the close state and a track of the fingertip in the close state,

determining, based on the recognized track, whether or not in the close state, the fingertip is in a swing state in which the fingertip swings;

enlarging and displaying one or a plurality of the operation images displayed below the track when the fingertip is determined to be in the swing state;

determining a swing range of the fingertip based on the track; and

enlarging the operation image such that a width of the operation image after being enlarged in an up/down direction is wider than a width of the swing range in the up/down direction and that a width of the operation image after being enlarged in a left/right direction is wider than a width of the swing range in the left/right direction,

wherein the swing state comprises a trembling or at least one switching of direction of movement.
