An information processing apparatus includes a first unit and a second unit supplied with power that can be interrupted individually, a power supply switch configured to be operated by a user, to turn off a power supply of the information processing apparatus, a controller configured to perform shutdown processing of the information processing apparatus thereby interrupting supply of power to the first unit and the second unit, upon turning off of the power supply switch, a first timer unit configured to interrupt the supply of the power to the first unit, after a lapse of a first predetermined time after turning off the power supply switch, and a second timer unit configured to interrupt the supply of power to the second unit, after a lapse of a second predetermined time after turning off the power supply switch. The second predetermined time is longer than the first predetermined time.

A hardware circuit (403) outputs different output signals between a case where an operation of an operating switch (402) is continued for longer than a threshold time and the other cases. An operation detecting CPU (404) outputs different output signals between a case of having detected the operation of the operating switch (402) and the other case. A signal generating section (405) feeds a control signal for switching the power supply mode to an off mode into a power control section (401): when the hardware circuit (403) outputs an output signal different from an output signal for the case where the operation is continued for longer than the threshold time and the operation detecting CPU (404) outputs an output signal for the case of having detected the operation; or when the hardware circuit (403) outputs the output signal for the case where the operation is continued for longer than the threshold time and the operation detecting CPU (404) outputs an output signal different from the output signal for the case of having detected the operation.

An electronic apparatus is provided that operates in a first state, a second state that consumes less energy than the first state, and a third state that consumes less energy than the second state. The electronic apparatus includes a switch that activates or cancels an automatic power-on function of the electronic apparatus, and a processor that shifts the electronic apparatus from the first state to the second state, in a case where, when the electronic apparatus is in the first state, a state transition condition for shifting the electronic apparatus to another state that consumes less energy than the first state is satisfied, and the automatic power-on function is active, and shifts the electronic apparatus from the first state to the third state, in a case where the state transition condition is satisfied and the automatic power-on function is inactive.

An image reading apparatus, comprising a memory that can transition from a normal mode to a power saving mode based on an inputted control signal, and a control unit that controls the control signal based on a synchronization signal that indicates a timing at which an image processing module outputs image data to a reading unit or a print unit.

A system and method for maintaining safe social distancing during device operation comprises a multifunction peripheral configured to scan or print a tangible document. A camera captures electronic images of two or more people proximate to the multifunction peripheral. A processor determines a relative distance between the people in accordance with captured electronic images and generates an alarm when a determined relative distance is less than a predetermined alarm threshold distance. The processor disables operation of the multifunction peripheral when the determined relative distance is less than the predetermined alarm threshold distance.

An information processing apparatus includes a controller that controls the information processing apparatus by making a transition of a state of the information processing apparatus in relation to power consumption of the information processing apparatus from a first state to a second state in which the power consumption is higher than that in the first state, and a line-of-sight detector that detects a line of sight toward the information processing apparatus. The controller makes a transition from the first state to the second state when the line-of-sight detector detects a line of sight toward the information processing apparatus.

An information processing apparatus includes, a reception unit configured to receive an instruction to transfer the information processing apparatus to the second power state, an analysis unit configured, when the reception unit receives the instruction, to analyze a factor limiting the transfer of the information processing apparatus to the second power state, and a control unit configured, when the analysis unit analyzes the factor and as a result the factor is a first factor, to control the information processing apparatus to transfer to the third power state without waiting until the factor is resolved, and configured, when the factor is a second factor, to control the information processing apparatus to wait until the factor is resolved, and to transfer to the second power state.
