Abstract

Upon determination that a portable terminal device is in a conversation state, a CPU disables a touch panel. The CPU determines whether an external output device is connected to the portable terminal device via a connector. Upon determination that the external output device is connected to the portable terminal device via the connector, the CPU enables the disabled touch panel. Upon determination that a handsfree function is effective, the CPU enables the disabled touch panel. The CPU determines whether a touch panel button is enabled. Upon determination that the touch panel button is enabled, the CPU enables the disabled touch panel.

Claims

1. A portable terminal device having a conversation function, comprising:

an input unit using a touch panel and an operating key button; and

a control unit adjusting a recognition rate of said touch panel, wherein

said operating key button has a conversation button for exerting the conversation function, and

said control unit disables said touch panel upon detection of depression of said conversation button by a user.

2. The portable terminal device according to claim 1, further comprising:

a connector establishing a connection between said portable terminal device and an external device, wherein

when said external device is connected to said portable terminal device via said connector, said control unit adjusts the recognition rate of said touch panel to enable said disabled touch panel upon detection of the depression of said conversation button by the user.

3. The portable terminal device according to claim 1, wherein

when a handsfree function is exerted in response to a command inputted by said user, said control unit adjusts the recognition rate of said touch panel to enable said disabled touch panel upon detection of the depression of said conversation button by the user.

4. The portable terminal device according to claim 1, wherein

said operating key button has a touch panel button for enabling said disabled touch panel in response to a command inputted by said user, and

when said user depresses said touch panel button, said control unit adjusts the recognition rate of said touch panel to enable said disabled touch panel upon detection of the depression of said conversation button by the user.

5. A control method of a portable terminal device having a conversation function, comprising the steps of:

detecting input through a touch panel and input through a conversation button; and

adjusting a recognition rate of said touch panel, wherein the step of adjusting the recognition rate includes the step of upon detection of the input through said conversation button, disabling said touch panel.
