A device control apparatus and a corresponding method allow the smooth recovery from a power saving mode to a stand-by state without malfunction. When the power saving mode is on and a signal which causes the release of the power saving mode is received, an output of a sleep mode release signal is temporarily driven low. After a first predetermined time period has elapsed, a power supply and an oscillation device are started. After a second predetermined time, a sleep state of a control unit is released, and the device is returned to a stand-by state.
