Mobile terminal, method of controlling the same, and computer program of the same
First Claim
1. A mobile terminal provided with lock function and an authentication unit, in which manipulation of the mobile terminal is inhibited when the lock function is locked and the lock function is unlocked to allow a manipulation of the mobile terminal when a user is authenticated as a legitimate user by the authentication unit, the mobile terminal comprising:
- a control circuit which starts supply of an electric power to the authentication unit only in response to an incoming call when the lock function is locked and unlocks the lock function when a user is authenticated as a legitimate user by the authentication unit,wherein said control circuit supplies the electric power to the authentication unit over a predetermined period of time only in response to the incoming call, unlocks the lock function when the user is authenticated as a legitimate user within the predetermined period of time by the authentication unit, and stops the supply of the electric power to the authentication unit when the authentication by the authentication unit is not carried out within the predetermined period of time.

Abstract
A mobile telephone (1), when being folded, is set in a lock state by an opening/closing detection and lock mechanism (50), and then a control circuit (30) stops supply of an electric power to a fingerprint authentication unit (60). In this state, upon detection of an incoming call from an external apparatus, the control circuit (30) restarts the supply of the electric power to the fingerprint authentication unit (60), and when a user is authenticated as a legitimate user by the fingerprint authentication unit (60), instructs the opening/closing detection and lock mechanism (50) to carry out an unlocking operation.

1. A mobile terminal provided with lock function and an authentication unit, in which manipulation of the mobile terminal is inhibited when the lock function is locked and the lock function is unlocked to allow a manipulation of the mobile terminal when a user is authenticated as a legitimate user by the authentication unit, the mobile terminal comprising:
-
a control circuit which starts supply of an electric power to the authentication unit only in response to an incoming call when the lock function is locked and unlocks the lock function when a user is authenticated as a legitimate user by the authentication unit, wherein said control circuit supplies the electric power to the authentication unit over a predetermined period of time only in response to the incoming call, unlocks the lock function when the user is authenticated as a legitimate user within the predetermined period of time by the authentication unit, and stops the supply of the electric power to the authentication unit when the authentication by the authentication unit is not carried out within the predetermined period of time. - View Dependent Claims (2, 3, 4, 5, 6)

9. A mobile terminal, comprising:
-
authentication means for authenticating whether a user is a legitimate user of the mobile terminal; lock means for inhibiting and allowing manipulation of the mobile terminal; lock control means for inhibiting manipulation of the mobile terminal by said lock means and for unlocking said lock means to allow manipulation of the mobile terminal when a user is authenticated as a legitimate user by said authentication means; detection means for detecting an incoming wireless call from an external apparatus; and a power supply control unit which starts supply of an electric power to said authentication means only in response to detection of an incoming wireless call by said detection means when said lock means is locked.

10. A method of controlling a mobile terminal provided with lock function and an authentication unit, in which manipulation of the mobile terminal is inhibited when the lock function is locked and the lock function is unlocked to allow manipulation of the mobile terminal when a user is authenticated as a legitimate user by the authentication unit, the method comprising the steps of:
-
supplying electric power to the authentication unit for a predetermined period of time only in response to an incoming call when the lock function is locked; unlocking the lock function when a user is authenticated as a legitimate user by the authentication unit within the predetermined period of time, stopping the supply of the electric power to the authentication unit when the authentication by the authentication unit is not carried out within the predetermined period of time. - View Dependent Claims (11)

12. A computer readable medium encoded with a computer program for operation control for a mobile terminal provided with a lock function and an authentication unit, in which manipulation of the mobile terminal is inhibited when the lock function is locked and the lock function is unlocked to allow manipulation of the mobile terminal when a user is authenticated as a legitimate user by the authentication unit, the computer program causing a computer to implement the steps of:
-
supplying electric power to the authentication unit for a predetermined period of time only in response to an incoming call when the lock function is locked, unlocking the lock function when a user is authenticated as a legitimate user by the authentication unit within the predetermined period of time, stopping the supply of the electric power to the authentication unit when the authentication by the authentication unit is not carried out within the predetermined period of time. - View Dependent Claims (13)
