Abstract

The present invention provides an information processing apparatus having a system body, body operation means provided on the system body, and remote operation means for use in performing a remote operation of the system body, the information processing apparatus being configured to perform processing according to operational information obtained by the body operation means or the remote operation means. The information processing apparatus includes means for distinguishing between the operation by the body operation means and the operation by the remote operation means. Power control of each device in the system body is performed according to a first set state during the operation of the body operation means. When the operation of the remote operation means is performed in a battery powered condition, power control of each device in the system body is performed according to a second set state where power consumption is lower than that in the first set state.

Claims

1. An information processing apparatus having a system body, body operation means provided on said system body, and remote operation means for use in performing a remote operation of said system body, said information processing apparatus being configured to perform processing according to operational information obtained by said body operation means or said remote operation means;

said information processing apparatus comprising means for distinguishing between the operation by said body operation means and the operation by said remote operation means;

wherein

power control of each device in said system body is performed according to a first set state during the operation of said body operation means; and

when the operation of said remote operation means is performed in a battery powered condition, power control of each device in said system body is performed according to a second set state where power consumption is lower than that in said first set state.

2. The information processing apparatus according to claim 1, wherein when the operation of said body operation means is performed during the power control of each device in said system body according to said second set state, said second set state is changed to said first set state.

3. The information processing apparatus according to claim 1, wherein the whole or part of the operation of said body operation means is invalidated in said second set state.

4. A control method for an information processing apparatus configured to perform processing according to operational information obtained by body operation means provided on a system body or remote operation means for use in performing a remote operation of said system body;

said control method comprising the steps of;

distinguishing between the operation by said body operation means and the operation by said remote operation means;

performing power control of each device in said system body according to a first set state during the operation of said body operation means; and

performing power control of each device in said system body according to a second set state where power consumption is lower than that in said first set state when the operation of said remote operation means is performed in a battery powered condition.
