Abstract

An image forming apparatus includes a detection unit configured to detect an object, a reception unit configured to receive an operation of a user, and a shifting unit configured to shift, if the detection unit detects an object, a power state of the image forming apparatus from a first power state to a second power state different from the first power state, and shift, if the reception unit receives an operation of a user, the power state of the image forming apparatus from the second power state to the first power state.

4. The information processing apparatus according to claim 3, further comprising:

a power supply unit which outputs power to the device; and

a switch which is arranged between the power supply unit and the device,

wherein the switch is turned on in accordance with the signal.

5. The information processing apparatus according to claim 1, wherein the power controller outputs a signal for shifting the information processing apparatus from the second power state to the first power state based on the detection of the human by the sensor, and

wherein the power controller disables the shift of a power state based on the user interface during the predetermined period after the power controller outputs the signal before completion of a shift from the second power state to the first power state based on the signal.

6. The information processing apparatus according to claim 1, further comprising:

a printer which prints an image on a sheet.

7. The information processing apparatus according to claim 1, wherein the sensor is a pyroelectric sensor.

8. The information processing apparatus according to claim 1, wherein the sensor is an infrared ray array sensor.

9. The information processing apparatus according to claim 1, wherein the device is a display.

10. The information processing apparatus according to claim 1, further comprising a display, wherein the device is a backlight of the display.

11. The information processing apparatus according to claim 1, wherein the user interface is a hard button.

12. An information processing apparatus having at least a first power state and a second power state, power being supplied to a device of the information processing apparatus in the first power state, power supply to the device being stopped in the second power state, comprising:

a sensor which detects a human around the information processing apparatus;

a user interface which receives a user operation to shift the information processing apparatus from the first power state to the second power state or to shift the information processing apparatus from the second power state to the first power state; and

a power controller which shifts the information processing apparatus from the second power state to the first power state based on a detection of a human by the sensor, and shifts the information processing apparatus, from the second power state to the first power state or from the first power state to the second power state, based on the user operation received by the user interface,

wherein, after the sensor having detected a human, the power controller disables a shift of a power state of the information processing apparatus based on the user interface temporarily.

13. The information processing apparatus according to claim 12, wherein the power controller disables the shift of a power state based on the user interface temporarily, after the detection of the human by the sensor before completion of a shift from the second power state to the first power state based on the detection of the human by the sensor.
