Energy-saving control method involving an energy-saving mode

A non-transitory computer-readable recording medium storing an energy-saving control program executable by a computer in an electronic apparatus, the energy-saving control program comprising:

• a first program code for causing the computer to receive an operation input from a plurality of operation input units and enable operations by processing based on different functions;
• a second program code for causing the computer to perform the processing based on the different functions by at least one of operating units operating after the operation input;
• a third program code for causing the computer to perform energy-saving control for shifting one or more of the operating units to an energy-saving mode and reactivating one or more of the operating units from the energy-saving mode, and as a partial reactivation mode, reactivate one or more of the operating units necessary for the operation after the operation input when the operation input during the energy-saving mode is common to a plurality of functions;
• and
• a fourth program code for causing the computer to switch to a reactivation mode for reactivation from the energy-saving mode, the reactivation mode being set in the third program code for the energy-saving control,
• wherein, in addition to the partial reactivation mode, the reactivation mode includes:
• a full reactivation mode for reactivating all the operating units in response to any operation input;
• and
• a combined reactivation mode for using the full reactivation mode and the partial reactivation mode together, and performing reactivation based on the full reactivation mode only in response to a specific operation other than the operation input.

An energy-saving control method, comprising:

• receiving, via a plurality of operation input units, an operation input and enabling operations by processing based on different functions;
• performing, via an operating unit group, the processing based on the different functions by at least one of operating units operating after the operation input;
• performing, via an energy-saving control unit, energy-saving control for shifting one or more of the operating units to an energy-saving mode and reactivating one or more of the operating units from the energy-saving mode, and as a partial reactivation mode, reactivating one or more of the operating units necessary for the operation after the operation input when the operation input during the energy-saving mode is common to a plurality of functions;
• and
• switching, via a reactivation mode switching unit, to a reactivation mode for reactivation from the energy-saving mode, the reactivation mode being set in the energy-saving control unit,
• wherein, in addition to the partial reactivation mode, the reactivation mode includes:
• a full reactivation mode for reactivating all the operating units in response to any operation input;
• and
• a combined reactivation mode for using the full reactivation mode and the partial reactivation mode together, and performing reactivation based on the full reactivation mode only in response to a specific operation other than the operation input.
