Abstract

An image forming apparatus includes an image capture device that captures a user image and generates a captured image, a document holding determination unit that determines whether or not the user appearing in the captured image holds a document based on the captured image, and a scanned data processor that performs processing including scanning the document. The scanned data processor is activated if the document holding determination unit determines that the user holds the document.

Claims

1. An image forming apparatus, comprising:

an image capture device configured to capture an image of a user to generate a captured image;

a scanned data processor configured to perform at least a document scanning operation; and

circuitry configured to

determine whether or not the captured image shows that the user appearing in the captured image holds a document, and

activate the scanned data processor in response to the determination that the captured image shows that the user holds a document.

2. The image forming apparatus according to claim 1, further comprising a printer configured to form an image on a recording sheet based on a print job issued by the user,

wherein the circuitry is configured to activate the printer in response to the determination that the captured image shows that the user does not hold a document.

3. The image forming apparatus according to claim 2, wherein the scanned data processor is configured to function as a scanner that generates image data, a copier that outputs an image on recording paper, or a facsimile device that performs a facsimile function.

4. The image forming apparatus according to claim 1, wherein the circuitry is further configured to:

extract a hand region of the captured image in which a user hand appears;

extract a closed region that contacts the hand region; and

determine whether or not the closed region corresponds to a document region where a document appears.

5. The image forming apparatus according to claim 4, wherein the circuitry is further configured to:

determine a size of the document based on image characteristics in the closed region; and

determine that the captured image shows that the user does not hold a document if the determined size of the document is either larger or smaller than a predetermined document size by more than a predetermined ratio.

6. The image forming apparatus according to claim 1, wherein the scanned data processor is configured to function as a scanner that generates image data, a copier that outputs an image on recording paper, or a facsimile device that performs a facsimile function.

7. The image forming apparatus according to claim 4, wherein the circuitry is further configured to

determine a type of the document that the user holds based on image characteristics in the document region, and

set an auxiliary parameter used in accordance with the type of the document.

8. The image forming apparatus according to claim 4, wherein the circuitry is further configured to

perform a character recognition process on the document region, and

set a facsimile destination number for the image forming apparatus based on a result of the character recognition process.

9. The image forming apparatus according to claim 1, wherein the circuitry is further configured to

authenticate the user who appears in the captured image, and

prepare the scanned data processor for an allowed function in accordance with authority of the authenticated user.

10. The image forming apparatus according to claim 8, wherein the circuitry is further configured to

identify a recognized telephone number based on the result of the character recognition process,

determine if a stored destination number in stored telephone number registration data that associates identification information that identifies the user with the stored destination number corresponds to the recognized telephone number, and

set the stored destination number as the facsimile destination number when the stored destination number corresponds to the recognized telephone number.

11. The image forming apparatus according to claim 6, wherein the circuitry is further configured to

authenticate the user who appears in the captured image, and

prepare the scanned data processor for allowed functions in accordance with authority of the authenticated user.

12. The image forming apparatus according to claim 11, wherein, the circuitry is further configured to

check stored function availability data that associates identification information that identifies the user with functional information that indicates functions of the image forming apparatus available to the user, and

activate the scanned data processor when a check result indicates that a function performed by the scanned data processor is available to the user.

13. The image forming apparatus according to claim 3, wherein the circuitry is further configured to

authenticate the user who appears in the captured image, and

enable one or more functions of the scanned data processor based on information corresponding to the authenticated user.

14. The image forming apparatus according to claim 2, further comprising a print job storage that stores the print job associated with identification information that identifies the user who issued the print job,

wherein the printer is configured to obtain the print job from the print job storage.

15. The image forming apparatus according to claim 1, further comprising a rangefinder to measure a distance between the image forming apparatus and the user,

wherein the image forming apparatus is activated if the measured distance reaches a predetermined threshold distance.

19. The image forming apparatus according to claim 1, wherein the circuitry is further configured to

activate a facsimile function without activating a printing function in response to the determination that the captured image shows that the user holds a document, and

activate the printing function in response to the determination that the captured image shows that the user does not hold a document.

16. An image forming method, comprising:

capturing an image of a user to generate a captured image;

determining whether or not the captured image shows that the user appearing in the captured image holds a document; and

activating a scanned data processor in response to the determination that the captured image shows that the user holds a document, the scanned data processor being configured to perform at least a document scanning operation.

18. The image forming method according to claim 16, further comprising:

in response to the determination that the captured image shows that the user holds a document, determining a document type of the document held by the user based on the captured image;

in response to the determination that the captured image shows that the user holds a document and a determination that the document type of the document held by the user is for facsimile, activating a facsimile function of the scanned data processor; and

in response to the determination that the captured image shows that the user holds a document and a determination that the document type of the document held by the user is not for facsimile, activating a copying function of the scanned data processor.

20. The image forming method according to claim 16, further comprising:

activating a facsimile function without activating a printing function in response to the determination that the captured image shows that the user holds a document; and

activating the printing function in response to the determination that the captured image shows that the user does not hold a document.

17. A non-transitory, computer-readable recording medium storing a program that, when executed by a computer, causes a processor of the computer to implement an image forming method, the method comprising:

capturing an image of a user to generate a captured image;

determining whether or not the captured image shows that the user appearing in the captured image holds a document; and

activating a scanned data processor in response to the determination that the captured image shows that the user holds a document, the scanned data processor being configured to perform at least a document scanning operation.
