FIG. 3 is a block diagram of the human detection device 100, and FIG. 4 is a schematic diagram showing a human detection range in the image forming apparatus 1.
Hereinafter, the configuration and operation of the human detection device 100 will be described with reference to the drawings.

(2.1) Schematic Configuration and Operation of Human Detection Device The human detection device 100 includes a monitoring camera 110, a human sensor 120, an image storage unit 130, a determination processing unit 140, a face recognition processing unit 150, a transmission unit 160, and a control unit. 170.
The determination processing unit 140 determines the presence of an intruder in the space where the image forming apparatus 1 is installed based on the image data stored in the image storage unit 130 and the image data output from the monitoring camera 110. .
When it is determined that there is a person in the space, the face recognition processing unit 150 compares the video (image data) from the monitoring camera 110 with the image data stored in the image storage unit 130 in advance. Then, face recognition processing is executed on the imaged person to determine whether or not the person is registered in advance.

When there is a difference greater than that determined as a result of the comparison, the transmission unit 160 transmits the image data captured by the monitoring camera 110 to the outside. Transmission of image data to the outside is performed via a communication line connected to the control unit 170.
The image storage unit 130, the determination processing unit 140, the face recognition processing unit 150, the transmission unit 160, and the control unit 170 form an image as a SoC (System on a Chip) integrated on a semiconductor chip together with a microprocessor, a memory, and the like. The image forming apparatus control unit 11 that controls the operation of the apparatus 1 can be provided independently.

(2.2) Surveillance Camera The surveillance camera 110 includes an imaging unit 111 and a video output unit 112. The imaging unit 111 further includes an image sensor 111a (not shown) and an optical lens 111b (not shown) that forms an optical image in the light receiving area of the image sensor 111a. In addition, the imaging unit 111 includes other necessary circuits and the like.
The image sensor 111a detects the presence / absence, shape (contour), etc. of a person's face area or a whole body area of a moving person in a predetermined monitoring area of the space where the image forming apparatus 1 is installed. For example, an image sensor (CCD image sensor or CMOS image sensor) is applicable.

  The video output unit 112 outputs the video captured by the imaging unit 111 to the image storage unit 130. Specifically, the video output unit 112 performs processing such as digital conversion and noise removal on the imaging data output from the image sensor 111a, and outputs the obtained digital data to the image storage unit 130 as video. To do.

  The monitoring camera 110 also includes an imaging direction variable mechanism 113 (not shown) that changes the imaging direction of the imaging unit 111 in accordance with an instruction from the control unit 170. Specifically, the imaging direction variable mechanism 113 is a turntable, a tilt mechanism, or the like incorporated in a general surveillance camera.

(2.3) Human sensor The human sensor 120 includes a pyroelectric element, a lens, an IC, a printed circuit board, and the like, detects a change amount of infrared rays that occurs when a person moves, and the detected change amount is predetermined. A pyroelectric sensor 121 that detects that a person has entered a predetermined area (detection range A1 shown in FIG. 4) and a substrate on which the pyroelectric sensor 121 is mounted. 122.

The horizontal detection range of the pyroelectric sensor 121 is a predetermined angle (displayed as an angle α in FIG. 4) that is symmetrical in all directions with respect to the center direction. That is, when the direction in which the detection surface is directed is the central direction, the angle range of the omnidirectional angle α with respect to the central direction is the detection range of the pyroelectric sensor 121.
In the image forming apparatus 1 according to the present embodiment, the detection range of the pyroelectric sensor 121 is indicated by halftone dots in FIG. 4 by disposing the exterior cover 5 on the front side of the pyroelectric sensor 121. This range is limited to a detection range A1 of the human sensor 120, which is 140 ° (2α) as an example.

  Regarding the detection range in the vertical direction of the pyroelectric sensor 121, an opening is formed in the exterior cover 5 only at a portion located below the center position of the pyroelectric sensor 121, and the floor surface on which the image forming apparatus 1 is installed. The horizontal distance at is a prescribed distance L1 indicated by a halftone dot in FIG. For example, the specified distance L1 is set to 0.8 m to 1.3 m (800 mm to 1300 mm).

  As a result, the detection range A1 of the human sensor 120 is widened by limiting the horizontal detection range and the vertical detection range of the pyroelectric sensor 121 to an obliquely lower side of the image forming apparatus 1. Thus, for example, detection of a passerby who does not plan to use the image forming apparatus 1 is suppressed.

  Similarly to the monitoring camera 110, a detection direction variable mechanism 123 (not shown) that changes the detection direction of the pyroelectric sensor 121 in accordance with an instruction from the control unit 170 is provided. Specifically, the detection direction variable mechanism 123 is a tilt mechanism or the like incorporated in a general sensor, and is in a vertical detection range of the pyroelectric sensor 121 when a second standby mode to be described later is selected. A certain specified distance L1 is enlarged.

(2.4) Power Saving Mode The image forming apparatus 1 according to the present embodiment has a plurality of power modes (operation modes) with different power consumption. Examples of the power mode include a warm-up mode when the power switch is turned on and the image forming apparatus 1 is turned on, and a run mode (normal mode) in which the received print job is executed and image forming processing is performed. And a standby mode for waiting for generation of a print job, and a power saving mode for suppressing power consumption of the image forming apparatus 1.
In the standby mode and the power saving mode, the power supplied to the image forming unit 2 is stopped or lower than the power amount in the normal mode. As a result, the power consumption amount in the power saving mode is lower than the power consumption amount in the normal mode.

Then, the image forming apparatus 1 transmits, as a power saving mode, a power amount necessary for capturing an image of a monitoring area determined for the monitoring camera 110 when the human sensor 120 detects a person. There is a standby mode and a second standby mode in which the monitoring camera 110 transmits a power amount necessary for capturing an image of a defined monitoring area regardless of the output of the human sensor 120.
Then, the first standby mode and the second standby mode can be selected and switched by the operator via the operation information unit 70. Further, a timer (not shown) set in the image forming apparatus control unit 11 may be selected for each time.

(3) Operation of the human detection device 100 The image forming apparatus 1 including the human detection device 100 configured as described above can be applied to a crime prevention system while reducing power consumption. Hereinafter, the operation of the security system in the image forming apparatus 1 using the human detection device 100 will be described.

(3.1) Comparison of Surveillance Camera and Pyroelectric Sensor While the power consumption of the surveillance camera 110 is 2 W to 10 W, the power consumption of the pyroelectric sensor 121 is 0.006 W.
On the other hand, the monitoring camera 110 takes about 0.1 seconds from when the power is turned off to when power is supplied to enable human imaging, whereas the pyroelectric sensor 121 takes about 30 seconds. Longer than the surveillance camera 110.
Further, as shown in FIG. 4, the detection range A1 of the pyroelectric sensor 121 is about 140 ° in the horizontal direction and 0.8 m to 1.3 m in the depth direction (horizontal distance on the floor). In contrast, the imaging range of the monitoring camera 110 is approximately 180 ° in the horizontal direction and the depth direction (horizontal distance L2 on the floor) is 2 m to 3 m, which is wider than A1.

The pyroelectric sensor 121 constituting the human sensor 120 is a sensor that detects that a person has entered the detection range A1 based on the amount of change in infrared rays that occurs when the person moves. If the stop position is within the detection range A1, it is not detected. Therefore, the human sensor 120 may not be able to detect the person if it is stopped even if a person exists on the near side of the operation information unit 70 of the image forming apparatus 1.
On the other hand, the surveillance camera 110 uses a wide space including the near side of the operation information unit 70 as a detection range A2, and when a person exists in the detection range A2, it detects even if the person is stopped.

Due to the difference in characteristics between the monitoring camera 110 and the human sensor 120, the image forming apparatus 1 according to the present embodiment has the following advantages.
That is, when the human sensor 120 that is always turned on during the power saving mode detects a person, the monitoring camera 110 is turned on, and a person who enters the detection range A1 is imaged and determined. Standby mode and the second standby mode in which the monitoring camera 110 is turned on regardless of the output of the human sensor 120 and the person entering the office, which is the space where the image forming apparatus 1 is installed, is imaged and determined. By adopting a configuration in which the user selects and sets the mode, power consumption is reduced compared to a configuration in which the monitoring camera 110 is always turned on during the power saving mode of the image forming apparatus 1 that is applicable to the security system. It becomes possible.

(3.2) First standby mode The pyroelectric sensor 121 is used as the human sensor 120, and power is constantly supplied to the human sensor 120, but power is supplied to the surveillance camera 110 by cutting off the power supply. Power is suppressed.
When the human sensor 120 detects a moving person, power is supplied to the monitoring camera 110, and when the monitoring camera 110 detects that a person approaches the image forming apparatus 1, a print job is generated. Transition to standby mode to prepare for and wait.
As a result, the necessary minimum power consumption is realized without impairing convenience.

In other words, it is possible to prevent erroneous detection of a detected moving body that is not a person or a person who is a person but only passes through (non-user).
Further, by analyzing the image data taken by the monitoring camera 110 and identifying the user based on individual authentication based on a personal information database registered in advance, the user's personal information is specified within an allowable range, and the purpose of use of the image forming apparatus 1 and the like. Can also be predicted.

(3.3) Second Standby Mode In the second standby mode, necessary power is supplied to the monitoring camera 110 regardless of whether or not there is an output from the human sensor 120, and the monitoring camera 110 Even if it detects that a person approaches the image forming apparatus, it does not shift to a standby mode that waits for the occurrence of a print job, but is used as a security system.

In the second standby mode, the presence of a person in the space (office) where the image forming apparatus 1 is installed is determined based on the image data captured by the monitoring camera 110.
When it is determined that there is a person in the space, the face recognition processing unit 150 compares the video (image data) from the monitoring camera 110 with the image data stored in the image storage unit 130 in advance. Then, face recognition processing is executed on the person, and it is determined whether or not the person corresponds to the person registered in advance. When there is a difference larger than the predetermined value as a result of the comparison, the image data is transmitted to the outside through the communication means.

Furthermore, in the second standby mode, the detection direction variable mechanism 123 of the human sensor 120 increases the specified distance L1 that is the vertical detection range of the pyroelectric sensor 121. Specifically, the image forming apparatus 1 is installed by expanding the detection area in the depth direction (horizontal distance on the floor surface) to about 5 m with the detection direction of the pyroelectric sensor 121 facing upward. Expand the human detection area in the space (office).
And when the human sensor 120 does not detect a moving body (person), the function as a crime prevention system is impaired by reducing the resolution and / or sensitivity of the surveillance camera 110 by reducing the power supplied to the surveillance camera 110. Without the need for minimum power consumption.

“Second Embodiment”
FIG. 5 is a schematic configuration diagram illustrating the entire appearance of the image forming apparatus 1A, and FIG. 6 is a schematic diagram illustrating a human detection range of the image forming apparatus 1A.
The basic configuration of the image forming apparatus 1 </ b> A of the present embodiment is the same as that of the image forming apparatus 1 of the first embodiment, and a face as a second imaging unit that captures an operator's face image on one end side of the operation information unit 70. This is different from the first embodiment in that it further includes a recognition camera 110A.
Hereinafter, the image forming apparatus 1A of the present embodiment will be described with reference to FIGS. 5 and 6. The same reference numerals are given to the same components as those of the image forming apparatus 1 according to the first embodiment, and the details thereof will be described. The detailed explanation is omitted.

(1) Face Recognition Camera The face recognition camera 110A detects the presence / absence of a moving body (person), a shape (contour), time-series movement information, and the like around the image forming apparatus 1. An image sensor (CCD image sensor or CMOS image sensor) is applicable.
Therefore, for example, in order to perform face authentication of a person approaching the image forming apparatus 1 instead of IC card authentication, a filter configuration suitable for face authentication (mainly, the face outline, eyes, nose, mouth, etc. are clear) The filter configuration is detected as shown in FIG.

Image forming apparatus 1A sets two regions (detection range A2 and detection range A3 in FIG. 6) by monitoring camera 110 and face recognition camera 110A.
A detection range A2 in FIG. 6 which is a relatively far detection area is a detection area by the monitoring camera 110, and has a function as a means for detecting a relatively remote moving body.
A detection range A3 in FIG. 6 which is a relatively close detection area is a detection area by the face recognition camera 110A, and has a function as a means for detecting a relatively close moving body.
Specifically, the detection range A3 is a range in which the operation information unit 70 of the image forming apparatus 1 can be operated, and is approximately 0 to 2 m as a guide.

(2) Canceling the crime prevention system As with the image forming apparatus 1, the image forming apparatus 1A requires the power required for the monitoring camera 110 in the second standby mode regardless of whether or not there is an output from the human sensor 120. Is used, and it is used as a crime prevention system without shifting to the standby mode in which it waits for the occurrence of a print job.

In the second standby mode, the presence of a moving body (person) in the space (office) where the image forming apparatus 1 is installed is determined based on the image data captured by the monitoring camera 110.
Then, in the second standby mode, when a face is detected within the detection range A3 by the face recognition camera 110A, the image data captured by the face recognition camera 110A is compared with the image data stored in advance. When it matches more than the given value, the mode is switched to the first standby mode.

  As a result, the image forming apparatus 1A used as a crime prevention system obtains information about the user with higher accuracy than the detection accuracy of the monitoring camera 110, and shifts to a standby mode in which it waits for the occurrence of a print job.
