Power controlling device, image processing apparatus, computer readable medium, and power controlling method

摘要

A power controlling device includes a detecting unit that detects a person in a detection area, a first imaging unit that takes an image of the person in a detecting range in an operating state, a second imaging unit that takes an image of a face of the person for use in user authentication in an operating state, and a power controller that supplies power to and brings the first imaging unit into the operating state if the person is detected, supplies power to and brings a processing unit that performs a process into an operating state if the approach of the person is determined on the basis of the taken image of the person, and supplies power to an brings the second imaging unit into the operating state during a period from the detection of the person to the shift of the processing unit to the operating state.

主权项

1. A power controlling device comprising:
a detecting unit, comprised of a sensor, that detects a person present in a detection area; a first imaging unit, comprised of a camera, that takes an image of a person present in a detecting range in an operating state; a second imaging unit, comprised of a second camera, that takes an image of a face of the person for use in user authentication in an operating state; an image processing unit, formed by a CPU and memory, that analyzes the images taken by the firs; imaging unit and the second imaging unit, a processing unit, comprised of a CPU and memory, that performs, in the operating state based on a result of user authentication, a process of reading an image of a document and generating image data, a process of forming an image on the basis of input image data, or a process of transmitting input image data to another image processing apparatus; and a power controller, which is implemented by the processing unit, that: supplies the first imaging unit with power necessary for the operation thereof to thereby bring the first imaging unit into the operating state from an off state if the person is detected by the detecting unit in the detection area, supplies the image processing unit with power necessary lot operation thereof to thereby bring the image processing unit from a sleep mode into an operating state if the person is detected by the detecting unit in the detection area: supplies a processing unit that performs a process with power necessary for the operation thereof to thereby bring the processing unit from a sleep mode into an operating state if the person is detected by the detecting unit in the detection area: supplies a processing unit that performs a process with power necessary for the operation thereof to thereby bring the processing unit into an operating state from a sleep mode in response to determining that the person is approaching on the basis of the image taken by the first imaging unit in the detecting range, and supplies the second imaging unit with power necessary for the operation thereof to thereby bring the second imaging unit, from an off state, into the operating state during a period from the detection of the person by the detection unit in the detection area to the shift of the processing unit from a sleep mode to the operating state.
