Abstract
An apparatus includes a storage, a connection unit that can transition to a first state where a command is receivable, a second state where a command is receivable and power saving is greater than in the first state, and a third state where the power saving is greater in the second state, and a control unit that can output a command to the connection unit. The control unit transmits to the connection unit a predetermined command for transiting the connection unit to the second state without supplying power to the storage, based on a predetermined return factor accepted in a power saving state where the connection unit is in the third power state and the power supply to the storage is stopped.
Claims20
An apparatus comprising:
- a storage that stores image data;
- a connection unit that transitions to a first state where a command is receivable, a second state where a command is receivable and power saving is greater than in the first state, and a third state where the power saving is greater than in the second state;
- a control unit that outputs a command to the connection unit;
- and
- a power control unit that controls power supply to the storage,
- wherein the control unit transmits to the connection unit a predetermined command for transiting the connection unit to the second state without supplying power to the storage, based on a predetermined return factor accepted in a power saving state where the connection unit is in the third power state and the power supply to the storage is stopped, and
- wherein the connection unit transitions to the second state based on the predetermined command.
A control method for an apparatus, the apparatus including a storage that stores image data, a connection unit that transitions to a first state where a command is receivable, a second state where a command is receivable and power saving is greater than in the first state, and a third state where the power saving is greater than in the second state, and a control unit that outputs a command to the connection unit, the method comprising:
- transiting the connection unit to a power saving state where the connection unit is the third state and power supply to the storage is stopped;
- receiving a predetermined return factor in the power saving state;
- transmitting to the connection unit a predetermined command for transiting the connection unit to the second state without supplying power to the storage, upon reception of the predetermined return factor, and
- transiting the connection unit to the second state based on the predetermined command
