Abstract

An electronic device includes: a memory including a data region that stores data; a display device; and at least one processor. At least one processor executes: first boot processing in which a boot time is constant irrespective of a usage state of data in the data region, first output processing of outputting information of a first pattern to the display device during execution of the first boot processing, second boot processing in which a boot time varies depending on a usage state of the data, and second output processing of outputting information of a second pattern to the display device until the second boot processing is completed.

First claim

What is claimed is:

1 . An electronic device comprising:
a memory including a data region that stores data; a display device; and at least one processor, wherein the at least one processor executes:
first boot processing in which a boot time is constant irrespective of a usage state of data in the data region,
first output processing of outputting information of a first pattern to the display device during execution of the first boot processing,
second boot processing in which a boot time varies depending on a usage state of the data, and
second output processing of outputting information of a second pattern to the display device until the second boot processing is completed.

2 . The electronic device according to claim 1 , wherein
a boot time taken to execute the second boot processing varies between a case where a state of the data region is a first state, and a case where a state of the data region is a second state different from the first state.

3 . The electronic device according to claim 1 , wherein
if the first boot processing is completed, then the at least one processor executes the second boot processing.

4 . The electronic device according to claim 1 , wherein
the at least one processor executes the first output processing in such a manner that output of information of the first pattern ends when the first boot processing taking a constant time is completed.

5 . The electronic device according to claim 1 , wherein
the at least one processor repeatedly outputs the information of the second pattern to the display device until the second boot processing is completed in the second output processing.

6 . The electronic device according to claim 1 , wherein
the first boot processing includes processing for bringing the electronic device into a state of being able to output sound corresponding to a play operation performed on the electronic device.

7 . The electronic device according to claim 1 , wherein
data to be acquired in accordance with an operation performed by a user is stored in the data region.

8 . The electronic device according to claim 1 , wherein
in a case where the data is not stored in the data region, the at least one processor does not cause the information of the second pattern to be output from the display device.

9 . The electronic device according to claim 1 , wherein
the second boot processing includes optimization processing of the data region.

10 . The electronic device according to claim 1 , wherein
the information includes at least either one of visual information and audio information.

11 . The electronic device according to claim 1 , wherein
the display device includes an LED, and a light emission pattern of the LED varies between the first boot processing and the second boot processing.

12 . The electronic device according to claim 11 , comprising an operation element, wherein
the display device further includes a display, and the at least one processor displays an image related to the operation element, on the display, and causes the operation element to emit light using the LED in a light emission pattern corresponding to the image, in the first output processing executed during execution of the first boot processing.

13 . The electronic device according to claim 12 , wherein
an image related to the operation element is an image corresponding to an operation on the operation element, and the at least one processor causes the light emission unit to emit light in accordance with display content of the image displayed on the display unit.

14 . The electronic device according to claim 12 , wherein
a plurality of the LEDs is included, a plurality of the operation elements is included, and the at least one processor causes LEDs corresponding to the plurality of operation elements, to emit light in a predetermined order in the second output processing executed during execution of the second boot processing.

15 . The electronic device according to claim 1 , wherein
the electronic device is an electronic musical instrument including a plurality of keys.

16 . A method for causing a computer including a memory including a data region that stores data, and a display device, to execute:
first boot processing in which a boot time is constant irrespective of a usage state of data in the data region; first output processing of outputting information of a first pattern to the display device during execution of the first boot processing; second boot processing in which a boot time varies depending on a usage state of the data; and second output processing of outputting information of a second pattern to the display device until the second boot processing is completed.

17 . A non-transitory computer-readable storage medium storing a program that causes a computer including a memory including a data region that store data, and a display device, to execute:
first boot processing in which a boot time is constant irrespective of a usage state of data in the data region; first output processing of outputting information of a first pattern to the display device during execution of the first boot processing; second boot processing in which a boot time varies depending on a usage state of the data; and second output processing of outputting information of a second pattern to the display device until the second boot processing is completed.
