| 1. An information processing apparatus comprising:
a detection unit for detecting at a first period of time a physical quantity as a target for detection;
a control unit configured to estimate an actual physical quantity based on a result of detection by the detection unit and
also controlling supply of a power to the detection unit;
a storage unit for storing therein the first period of time, said first period of time being shorter than a normal period
of time, which is needed after supply of a power to the detection unit by the control unit until a normal result of detection
by the detection unit is obtained, as a standby period with the control unit being shifted to a standby state, wherein said
control unit includes
an estimation unit configured to estimate the actual physical quantity from the physical quantity detected by the detection
unit at said first period of time,
wherein the control unit starts to supply power to the detection unit, shifts its own state to the standby state, then returns
from the standby state after passage of the standby period, and the estimation unit estimates the actual physical quantity
based on a result of detection by the detection unit and a difference in time between the first period of time and normal
period of time,
said control unit is configured to set its own operating state in a standby state after the power supplied to said detection
unit is stopped, and not perform another command without first entering the standby state.
