Abstract

A power supply control apparatus includes a sensor, a first imaging unit, a second imaging unit, and a state controller. The sensor senses a person when the power supply control apparatus is in a power saving state. The first imaging unit consumes higher power than the sensor and captures an image of a person approaching. The second imaging unit captures an image used to recognize a person. The state controller causes the first imaging unit and the second imaging unit to be in a power supply state in a case where the sensor has sensed a person.

Claims

1. A power supply control apparatus comprising:

a pyroelectric sensor configured to sense a person when the power supply control apparatus is in a power saving state;

a first camera configured to consume higher power than the sensor and configured to capture a first image of the person;

a second camera, separate from the first camera, configured to capture a second image used to recognize the person;

a first processor configured to execute a first state controller configured to cause the first camera to be in a power supply state in response to the pyroelectric sensor sensing the person; and

a second processor configured to execute a second state controller configured to cause the second camera to be in a power supply state in response to determining, from an image analysis of the captured first image of the person, that the person is approaching the power supply control apparatus,

wherein the second processor comprises a main controller of an image processing apparatus, which includes the power supply control apparatus, and

wherein the second processor is configured to switch to a power supply state in response to determining, from the image analysis of the captured first image of the person, that the person is approaching the image processing apparatus.

2. The power supply control apparatus of claim 1, wherein the first camera is configured to capture the first image of the person in a first detection area and the second camera is configured to capture the second image in a second detection area, and

wherein the first detection area and the second detection area have different sizes.

3. The power supply control apparatus of claim 1, wherein the first camera and the second camera are located at different positions on an image processing apparatus which includes the power supply control apparatus.

4. The power supply control apparatus of claim 1, wherein the second processor is configured to cause a user interface of the image processing apparatus to be in a power supply state in response to determining, from the image analysis of the captured first image of the person, that the person is approaching the image processing apparatus.

5. The power supply control apparatus of claim 4, wherein the second processor is configured to, in response to determining that the person will face the user interface, execute identity recognition processing using an image analysis of the captured second image.

6. The power supply control apparatus of claim 1, wherein the image processing apparatus is configured to perform at least one of a print operation or a fax operation.

7. An image processing apparatus comprising:

a pyroelectric sensor configured to sense a person when the image processing apparatus is in a power saving state;

a first camera configured to consume higher power than the sensor and configured to capture a first image of the person;

a second camera, separate from the first camera, configured to capture a second image used to recognize the person;

a first processor configured to execute a first state controller configured to cause the first camera to be in a power supply state in response to the pyroelectric sensor sensing the person; and

a second processor configured to execute a second state controller configured to cause the second camera to be in a power supply state in response to determining, from an image analysis of the captured first image of the person, that the person is approaching the image processing apparatus,

wherein the second processor comprises a main controller of the image processing apparatus, and

wherein the second processor is configured to switch to a power supply state in response to determining, from the image analysis of the captured first image of the person, that the person is approaching the image processing apparatus.

8. The image processing apparatus of claim 7, wherein the first camera is configured to capture the first image of the person in a first detection area and the second camera is configured to capture the second image in a second detection area, and

wherein the first detection area and the second detection area have different sizes.

9. The image processing apparatus of claim 7, wherein the first camera and the second camera are located at different positions on the image processing apparatus.

10. A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

sensing a person, using a pyroelectric sensor, when an image processing apparatus is in a power saving state;

capturing a first image of the person approaching using a first imaging unit, the capturing consuming higher power than the sensing;

capturing a second image used to recognize the person using a second imaging unit separate from the first imaging unit;

commanding, by a first state controller, executed a first processor, the first imaging unit to be in a power supply state in response to sensing the person; and

commanding, by a second state controller, executed by a second processor, the second imaging unit to be in a power supply state in response to determining, from an image analysis of the captured first image of the person, that the person is approaching the computer,

wherein the second processor comprises a main controller of the image processing apparatus, and

wherein the process further comprises switching the second processor to a power supply state in response to determining, from the image analysis of the captured first image of the person, that the person is approaching the image processing apparatus.

11. The non-transitory computer readable medium of claim 10, wherein the capturing the first image further comprises capturing the first image in a first detection area of the first imaging unit and the capturing the second image further comprises capturing the second image in a second detection area of the second imaging unit, and

wherein the first detection area and the second detection area have different sizes.

12. The non-transitory computer readable medium of claim 10, wherein the first imaging unit and the second imaging unit are located at different positions on the image processing apparatus.

13. The non-transitory computer readable medium of claim 10, wherein the process further comprises causing, using the second processor, a user interface of the image processing apparatus to be in a power supply state in response to determining, from the image analysis of the captured first image of the person, that the person is approaching the image processing apparatus.

14. The non-transitory computer readable medium of claim 13, wherein the process further comprises executing, by the second processor, in response to determining that the person will face the user interface, identity recognition processing using an image analysis of the captured second image.

15. The non-transitory computer readable medium of claim 10, wherein the process further comprises performing, using the image processing apparatus, at least one of a print operation or a fax operation.
