Abstract

It is made possible to cancel the effect of the already executed command without performing burdensome operation if an unobjective command is executed for input operation of the user.

An input signal analysis section 200 gives a command of execution of a first command corresponding to detection of input operation to a first operation button based on an input position of a touch panel 10 detected by an input signal control section 300 and if input operation to a second operation button is detected, gives a command of a second command corresponding to detection. If continuous input operation to the second operation button is detected after the first command corresponding to the first operation button is executed, and command change notification from the input signal analysis section 200 is received, an application 100 cancels the effect of the immediately preceding executed first command and executes the second command.

Claims

1. An input device of an electronic device, comprising:

an input section having an input function having input position information; and

an input control section giving a command of processing for input operation based on an input signal of said input section, wherein

said input control section has;

an input position detection section detecting an input position in said input section;

a command execution control section that executes a first command concerning a first function assigned to a first area in said input section and a second command concerning a second function different from the first function assigned to a second area different from the first area;

an input signal analysis section giving a command of execution of the first command if input operation to the first area is detected and giving a command of execution of the second command if input operation to the second area is detected based on the input position detected by the input position detection section; and

an input operation cancel control section executing cancel processing to cancel the effect of the immediately preceding executed first command if continuous input operation to the second area is detected after execution of the first command with detection of input operation to the first area by the input signal analysis section.

2. The input device of the electronic device as claimed in claim 1, comprising

a display section that displays a visible information concerning input operation;

and

a touch panel having an input function based on contact operation with an input face corresponding to a display screen of the display section as said input section, wherein

if continuous operation of a contact state from the first area to the second area is detected, the input signal analysis section determines that the operation is continuous input operation from the first area to the second area.

3. The input device of the electronic device as claimed in claim 1, wherein

if input operation to the second area is detected within a predetermined time from the detection time of the input operation start to the first area or the execution time of the first command accompanying the input operation, the input operation cancel control section executes the cancel processing and makes the cancel processing ineffective after a lapse of the predetermined time.

4. The input device of the electronic device as claimed in claim 1, comprising

a display section that can display visible information concerning input operation;

and

a screen display control section for controlling the display state of an object to be operated displayed on a display screen of the display section, wherein

the screen display control section displays objects to be operated at display screen positions corresponding to operation areas containing the first area and the second area and if the object is in a non-display state and input operation to the corresponding area is detected, places some or all of the objects containing the object corresponding to the input position in a display state, and wherein

if input operation to the second area is detected within a predetermined time from the detection time of the input operation start to the first area or the execution time of the first command accompanying the input operation, the input operation cancel control section executes the cancel processing and makes the cancel processing ineffective after a lapse of the predetermined time.

5. The input device of the electronic device as claimed in claim 4, wherein

if the object is in the non-display state and input operation to the corresponding area is detected, the screen display control section places the object corresponding to the input position and at least one different object in a display state and places the object other than the object corresponding to the input position in the non-display state when a predetermined time has elapsed since the display state, and wherein

when the different object is in the display state, if input operation to the different object is detected, the input operation cancel control section determines that the operation is continuous input operation from the first area to the second area and executes the cancel processing and if an object other than the object corresponding to the input position is switched from the display state to the non-display state, makes the cancel processing ineffective.

8. An electronic device installing an input device as claimed in claim 1.

6. An input operation processing method in an input device of an electronic device, comprising an input section having an input function having input position information and an input control section for giving a command of processing for input operation based on an input signal of said input section,

in the input control section, said input operation processing method having:

an input position detection step of detecting an input position in the input section;

a command execution control step of executing a first command concerning a first function assigned to a first area in the input section and a second command concerning a second function different from the first function assigned to a second area different from the first area based on input operation;

an input signal analysis step of giving a command of execution of the first command if input operation to the first area is detected and giving a command of execution of the second command if input operation to the second area is detected based on the input position detected by said input position detection step; and

an input operation cancel control step of executing cancel processing to cancel the effect of the immediately preceding executed first command if continuous input operation to the second area is detected after execution of the first command with detection of input operation to the first area by said input signal analysis step.

7. An input control program for causing a computer to the steps of the input operation processing method as claimed in claim 6.
