Abstract

An information processor having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to the amount of processing has periodic switching detection means of performing detection as to whether the information processor is periodically switching from a low-power-consumption operating mode in which the power consumption is lower to a high-power-consumption operating mode in which the power consumption is higher in the plurality of operating modes, and operating mode changing means of changing the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at the time of switching between the low-power-consumption operating mode and the high-power-consumption operating mode if the switching cycle detected by the periodic switching detection means is shorter than a set cycle determined in advance.

1. A method for controlling an information processor having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to an amount of processing, said method comprising:

a periodic switching detection step of performing detection as to whether the information processor is periodically switching from a low-power operating mode in the plurality of operating modes in which the power consumption is lower to a high-power operating mode in the plurality of operating modes in which the power consumption is higher; and

an operating mode changing step of changing the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the low-power operating mode and the high-power operating mode if a switching cycle detected by said periodic switching detection means is shorter than a set cycle determined in advance.

2. A method for controlling an information processor having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to an amount of processing, said method comprising:

an operation detection step of performing detection as to whether a cycle setting program is operating by which a cycle of switching from a low-power operating mode in which the power consumption is lower to a high-power operating mode in which the power consumption is higher in the plurality of operating modes is set shorter than a set cycle determined in advance; and

an operating mode changing step of changing, when the operating state of the cycle setting program is detected, the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the low-power operating mode and the high-power operating mode.

3. A method for controlling an information processor having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to an amount of processing, said method comprising:

an operation detection step of waiting for speech data or image data to be selected by a user and performing detection as to whether a reproduction application program for reproducing the speech data or image data is operating when the speech data or image data is selected by the user; and

an operating mode changing step of changing, when the operating state of the reproduction application program is detected, the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the operating modes in combination before detection of the reproduction application program.

4. A program for controlling a computer having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to an amount of processing, said program making the computer function as:

periodic switching detection means of performing detection as to whether the information processor is periodically switching from a low-power operating mode in which the power consumption is lower to a high-power operating mode in which the power consumption is higher in the plurality of operating modes; and

operating mode changing means of changing the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the low-power operating mode and the high-power operating mode if a switching cycle detected by said periodic switching detection means is shorter than a set cycle determined in advance.

5. A program for controlling a computer having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to an amount of processing, said program making the computer function as:

operation detection means of performing detection as to whether a cycle setting program is operating by which a cycle of switching from a low-power operating mode in which the power consumption is lower to a high-power operating mode in which the power consumption is higher in the plurality of operating modes is set shorter than a set cycle determined in advance; and

operating mode changing means of changing, when the operating state of the cycle setting program is detected, the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the low-power operating mode and the high-power operating mode.

6. A program for controlling a computer having a plurality of operating modes differing in power consumption and capable of changing the operating mode according to an amount of processing, said program making the computer function as:

operation detection means of waiting for speech data or image data to be selected by a user and performing detection as to whether a reproduction application program for reproducing the speech data or image data is operating when the speech data or image data is selected by the user; and

operating mode changing means of changing, when the operating state of the reproduction application program is detected, the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the operating modes in combination before detection of the reproduction application program.

periodic switching detection by detecting whether the information processor is periodically switching from a low-power operating mode in the plurality of operating modes to a high-power operating mode in the plurality of operating modes; and

operating mode changing by changing the operating modes between which the information processor switches to a combination of the operating modes such that the difference between the power consumptions is reduced relative to that at a time of switching between the low-power operating mode and the high-power operating mode if a switching cycle detected by said periodic switching detection means is shorter than a set cycle determined in advance.
