Abstract
An electronic apparatus capable of controlling power usage without interfering with execution of processes. When the electronic apparatus is requested to execute a process, it is determined whether or not power consumption while the requested process is executed is greater than a predetermined amount of power. When it is determined that the power consumption is greater than the predetermined amount of power, power required to execute the requested process is borrowed from another electronic apparatus. When the power required to execute the requested process is borrowed, the requested process is executed.
Claims7
An electronic apparatus comprising:
- a determination unit configured to, in a case where the electronic apparatus is requested to execute a process, determine whether power consumption for executing the requested process is greater than a predetermined amount of power;
- a notification unit configured to, in a case where the determination unit determines that the power consumption for executing the requested process is greater than the predetermined amount of power, notify another electronic apparatus that the power consumption for executing the requested process is greater than the predetermined amount of power by transmitting a power reallocation notification;
- and
- an execution unit configured to, after the notification unit notifies the other electronic apparatus that the power consumption for executing the requested process is greater than the predetermined amount of power, execute the requested process,
- wherein the other electronic apparatus, which has received the power reallocation notification from the notification unit and has reallocated power to the electronic apparatus in response to the power reallocation notification, is limited from sending a power reallocation notification in a case that the other electronic apparatus determines that the power consumption for executing a requested another process is greater than a reduced amount of available power.

A control method for an electronic apparatus comprising:
- a determination step of, in a case where the electronic apparatus is requested to execute a process, determining whether power consumption for executing the requested process is greater than a predetermined amount of power;
- a notification step of, in a case where it is determined in the determination step that the power consumption for executing the requested process is greater than the predetermined amount of power, notifying another electronic apparatus that the power consumption for executing the requested process is greater than the predetermined amount of power by transmitting a power reallocation notification;
- and
- an execution step of, after the notification step notifies the other electronic apparatus that the power consumption for executing the requested process is greater than the predetermined amount of power, executing the requested process,
- wherein the other electronic apparatus, which has received the power reallocation notification from the notification step and has reallocated power to the electronic apparatus in response to the power reallocation notification, is limited from sending a power reallocation notification in a case that the other electronic apparatus determines that the power consumption for executing a requested another process is greater than a reduced amount of available power.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for an electronic apparatus, the control method comprising:
- a determination step of, in a case where the electronic apparatus is requested to execute a process, determining whether power consumption for executing the requested process is greater than a predetermined amount of power;
- a notification step of, in a case where it is determined in the determination step that the power consumption for executing the requested process is greater than the predetermined amount of power, notifying another electronic apparatus that the power consumption for executing the requested process is greater than the predetermined amount of power by transmitting a power reallocation notification;
- and
- an execution step of, after the notification step notifies the other electronic apparatus that the power consumption for executing the requested process is greater than the predetermined amount of power, executing the requested process,
- wherein the other electronic apparatus, which has received the power reallocation notification from the notification step and has reallocated power to the electronic apparatus in response to the power reallocation notification, is limited from sending a power reallocation notification in a case that the other electronic apparatus determines that the power consumption for executing a requested another process is greater than a reduced amount of available power.
