Abstract
An image forming apparatus and a method of controlling the image forming apparatus are provided. The method includes receiving a reflection signal corresponding to a transmission signal transmitted from the image forming apparatus to a user sensing area, the reflection signal being reflected from a user, determining a distance between the image forming apparatus and the user, based on the received reflection signal, selecting a power consumption mode corresponding to the determined distance from among a plurality of power consumption modes, based on the distance between the image forming apparatus and the user, and performing user authentication or power control according to the selected power consumption mode.
Claims20
A method of controlling an image forming apparatus, the method comprising:
- setting a weight value of at least one location in a user sensing area, based on a probability that the user will move to a location for performing an image forming operation;
- receiving a reflection signal corresponding to a transmission signal transmitted from the image forming apparatus to the user sensing area, the reflection signal reflected from the user;
- determining a location of the user based on the received reflection signal;
- determining a distance between the image forming apparatus and the user based on the determined location of the user;
- selecting a power consumption mode, from among a plurality of power consumption modes, based on the determined distance between the image forming apparatus and the user;
- and
- performing user authentication or power control according to the selected power consumption mode,
- wherein a time for selecting the power consumption mode is based on the set weight value.
An image forming apparatus comprising:
- an image former to perform an image forming operation;
- a signal transceiver to receive a reflection signal corresponding to a transmission signal transmitted from the image forming apparatus to a user sensing area and reflected from a user;
- at least one processor to:
- set a weight value of at least one location in a user sensing area, based on a probability that the user will move to a location for performing the image forming operation,
- determine a location of the user based on the received reflection signal,
- determine a distance between the image forming apparatus and the user based on the determined location of the user, and
- select a power consumption mode, from among a plurality of power consumption modes, based on the determined distance between the image forming apparatus and the user;
- and
- a power supply to supply power to the image forming apparatus, based on the selected power consumption mode,
- wherein the at least one processor performs user authentication or power control according to the selected power consumption mode, and
- wherein a time for selecting the power consumption mode is based on the set weight value.
A non-transitory computer-readable recording medium having recorded thereon instructions, executable by at least one processor, to control an image forming apparatus, the non-transitory computer-readable recording medium comprising:
- instructions to set a weight value of at least one location in a user sensing area, based on a probability that the user will move to a location for performing an image forming operation;
- instructions to receive a reflection signal corresponding to a transmission signal transmitted from the image forming apparatus to the user sensing area, the reflection signal reflected from the user;
- instructions to determine a location of the user based on the received reflection signal;
- instructions to determine a distance between the image forming apparatus and the user based on the determined location of the user;
- instructions to select a power consumption mode, from among a plurality of power consumption modes, based on the determined distance between the image forming apparatus and the user;
- and
- instructions to perform user authentication or power control according to the selected power consumption mode,
- wherein a time for selecting the power consumption mode is based on the set weight value.
