Abstract

An image processing apparatus including: a first storage unit; a second storage unit that has a higher storage capacity than that of the first storage unit and a longer start-up time than that of the first storage unit; and a control unit that, after shifting to a power-saving mode in which power consumption is reduced by shutting off power supply at least to the second storage unit, starts a recovery process from the power-saving mode upon occurrence of a recovery request from the power-saving mode to perform a processing operation using the second storage unit, starts the processing operation with the first storage unit as a data storing destination when the first storage unit is ready for use, and switches the data storing destination from the first storage unit to the second storage unit when the second storage unit is ready for use.

Claims

1. An image processing apparatus comprising:

a first storage unit;

a second storage unit that has a higher storage capacity than that of the first storage unit and a longer start-up time than that of the first storage unit; and

a control unit that, after shifting to a power-saving mode in which power consumption is reduced by shutting off power supply at least to the second storage unit, starts a recovery process from the power-saving mode upon occurrence of a recovery request from the power-saving mode to perform a processing operation using the second storage unit, starts the processing operation with the first storage unit as a data storing destination when the first storage unit is ready for use, and switches the data storing destination from the first storage unit to the second storage unit when the second storage unit is ready for use.

2. The image processing apparatus according to claim 1, wherein

the control unit determines that the second storage unit has been ready for use by timing a prescribed recovery time, information of the prescribed recovery time being stored in advance in the first storage unit as a time required for start-up of the second storage unit.

3. The image processing apparatus according to claim 1, wherein

the control unit determines that the second storage unit has been ready for use by detecting a recovery completion notification output therefrom when the second storage unit has been ready for use.

4. The image processing apparatus according to claim 1, wherein

after switching the data storing destination from the first storage unit to the second storage unit, the control unit copies data stored in the first storage unit to the second storage unit, and deletes the data from the first storage unit.

5. The image processing apparatus according to claim 4, wherein

the control unit generates a file including data stored in the second storage unit and the data copied from the first storage unit to the second storage unit.

6. A recovery control method comprising:

a first storing processing includes storing data in a first storage unit;

a second storing processing includes storing data in a second storage unit having a higher storage capacity than that of the first storage unit and a longer start-up time than that of the first storage unit; and

process controlling includes, after shifting to a power-saving mode in which power consumption is reduced by shutting off power supply at least to the second storage unit,

starting a recovery process from the power-saving mode upon occurrence of a recovery request from the power-saving mode to perform a processing operation using the second storage unit,

performing the first storing processing when the first storage unit is ready for use to store data in the first storage unit,

switching the data storing destination to the second storage unit when the second storage unit is ready for use, and

performing the second storing processing to store data in the second storage unit.

7. A computer program product comprising a non-transitory computer-usable medium having a computer-readable program code embodied in the medium causing a computer to execute:

a first storing processing includes storing data in a first storage unit;

a second storing processing includes storing data in a second storage unit having a higher storage capacity than that of the first storage unit and a longer start-up time than that of the first storage unit; and

process controlling includes, after shifting to a power-saving mode in which power consumption is reduced by shutting off power supply at least to the second storage unit,

starting a recovery process from the power-saving mode upon occurrence of a recovery request from the power-saving mode to perform a processing operation using the second storage unit,

performing the first storing processing when the first storage unit is ready for use to store data in the first storage unit,

switching the data storing destination to the second storage unit when the, second storage unit is ready for use, and

performing the second storing processing to store data in the second storage unit.
