Image processing apparatus, power-saving recovery control method, and computer program product
First Claim
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.

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.
