Abstract

An electronic appliance which is carried by a user, the electronic appliance includes: a first processor configured to perform a first operating system, and to perform a first process of a user interface when the booting of the first operating system is completed; and a second processor configured to perform a second operating system which is booted within a shorter time period than the first operating system, to perform a second process of a user interface in which a user instruction is acquired from an input unit shared by the first processor when the booting of the second operating system is completed, and to suppress execution of the second process of the user interface when the booting of the first operating system is completed.

Claims

1. An electronic appliance which is carried by a user, the electronic appliance comprising:

a first processor configured to perform a first operating system, and to perform a first process of a user interface when the booting of the first operating system is completed; and

a second processor configured to perform a second operating system which is booted within a shorter time period than the first operating system, to perform a second process of a user interface in which a user instruction is acquired from input means shared by the first processor when the booting of the second operating system is completed, and to suppress execution of the second process of the user interface when the booting of the first operating system is completed.

2. The electronic appliance according to claim 1, wherein the first processor allows the second processor to start the booting of the second operating system, and then starts the booting of the first operating system.

3. The electronic appliance according to claim 1, wherein the first processor writes data that indicates a factor of booting to a storage area used by the second process of the user interface, and

the second processor executes the second process of the user interface depending on a factor of booting in accordance with data that indicates the written factor of booting.

4. The electronic appliance according to claim 1, wherein the second processor, as a part of the first process of the user interface, executes a process similar to the second process of the user interface.

5. A startup method of an electronic appliance which is carried by a user, the method comprising:

performing a first process of a user interface when the booting of a first operating system is completed by a first processor configured to perform the first operating system;

performing a second process of a user interface in which a user instruction is acquired from input means shared by the first processor when the booting of a second operating system is completed by a second processor configured to perform the second operating system which is booted within a shorter time period than the first operating system; and

suppressing execution of the second process of the user interface when the booting of the first operating system is completed.
