Embodiments to which the present invention is applied will be described below with reference to the drawings.
[First Embodiment]
<Configuration>
As shown in FIGS. 1 and 2, the partition forming system of the first embodiment is for forming a partition (partition) 19 as a visible image that blocks a field of view in an office or the like. A personal computer (hereinafter referred to as “PC”) 9. The office illustrated in FIG. 2 is shared by a plurality of users 81, and a desk 82, a chair 83, a PC 9, and the like for each user 81 are installed.

  As shown in FIG. 2, the image forming apparatus 1 is installed on the ceiling 84 of the office. As shown in FIG. 1, the laser light source 11, the scanning unit 12, the condensing lens 13, the driving unit 14, and the like. The communication unit 15 and the control unit 16 are provided.

  The laser light source 11 is an apparatus that oscillates in a wavelength region of 1 μm or more and emits a laser beam in an invisible region (in this example, an infrared laser beam). Infrared laser beams are less susceptible to atmospheric absorption and scattering and have the property of propagating far away. Specifically, for example, an Nd: YAG laser device, an Nd: Glass laser device, or a carbon dioxide laser device is used as the laser light source 11.

  The scanning unit 12 is a device for scanning an infrared laser beam in the XY direction (two-dimensional direction), and includes, for example, one or more rotating mirrors (for example, a plane mirror and a polygon mirror) and a swinging mirror.

The condensing lens 13 condenses the infrared laser beam scanned by the scanning unit 12.
The drive unit 14 adjusts the position of the condensing lens 13 in the two-dimensional direction (the position on the surface intersecting the optical axis of the condensing lens 13) according to the optical axis position of the infrared laser beam from the scanning unit 12. . The drive unit 14 adjusts the position of the condensing lens 13 in the optical axis direction according to the condensing position of the infrared laser beam.

The communication unit 15 is a communication device for performing data communication with the PC 9, and for example, a wireless LAN or wired LAN interface is used.
The control unit 16 controls each unit of the image forming apparatus 1 and includes a CPU, a ROM, a RAM, and the like. The control unit 16 receives control information from the PC 9 via the communication unit 15, and performs processing for forming a visible image (in this example, the partition 19) in the air according to the received control information.

  Specifically, the control unit 16 causes the laser light source 11 to emit an infrared laser beam, and the focusing lens 13 narrows the spot beam to a spot beam having a diameter of, for example, about 0.1 mm. Causes dielectric breakdown. As a result, the gas is locally in a high-density plasma state and flash is generated, and the condensed position is visually recognized as a light emitting point.

  And the control part 16 can adjust the condensing position of the laser beam in the air three-dimensionally in the XYZ direction by controlling the scanning part 12 and the drive part 14. That is, the control unit 16 can generate a light emitting point at a desired position in the air. Specifically, the control unit 16 drives the laser light source 11, the scanning unit 12, and the driving unit 14 in accordance with the visible image to be formed, thereby sequentially changing the gas at the position where the visible image is to be formed in the air. Plasma is emitted. By repeating such processing in a short time, it appears as if the human eye continuously emits light due to an afterimage, and thus a visible image appears to be formed in the air.

The PC 9 includes a power switch 91, an operation unit 92, a camera 93, a display unit 94, a storage unit 95, a communication unit 96, and a control unit 97.
The power switch 91 is a switch for turning on / off the power of the PC 9.

  The operation unit 92 is an input device for inputting a command by an external operation from the user 81, and for example, a keyboard or a pointing device (such as a mouse or a touch pad) is used.

The camera 93 is a photographing device for photographing the user 81, and is provided in the upper part of the display as shown in FIG. 2, for example.
The display unit 94 is an output device for displaying various types of information as an image that can be viewed by the user 81. For example, a liquid crystal display is used.

  The storage unit 95 is a non-volatile storage device that can rewrite stored data. For example, a hard disk device is used. The storage unit 95 stores various software (programs).

The communication unit 96 is a communication device for performing data communication with the image forming apparatus 1. For example, a wireless LAN or wired LAN interface is used.
The control unit 97 performs overall control of each part of the PC 9, and includes a CPU, a ROM, a RAM, and the like.

<Processing>
Next, the process performed by the partition formation system of this embodiment is demonstrated.
First, the formation instruction process executed by the control unit 97 of the PC 9 will be described with reference to the flowchart of FIG. The formation instruction process is started when the PC 9 is turned on. Specifically, dedicated software (program) installed in the PC 9 is executed when the PC 9 is activated, and the formation instruction process is started.

  First, in step S <b> 111, the control unit 97 transmits an instruction signal to the image forming apparatus 1 via the communication unit 96. The instruction signal is a signal for causing the image forming apparatus 1 to form the partition 19, and includes identification information of the PC 9. As will be described later, the image forming apparatus 1 forms the partition 19 when the instruction signal is received, and when no instruction signal is received for a set time T1 (for example, 10 seconds). The formation of the partition 19 is canceled (the partition 19 is erased). That is, while the instruction signal is periodically transmitted from the PC 9 to the image forming apparatus 1, the state in which the partition 19 is formed is maintained.

  The partition 19 formed by the image forming apparatus 1 is divided into a plurality of parts as shown in FIG. 4, for example, and formation and release processing are performed for each of the divided partitions 19. For example, in the process for the partition 19 (AB) shown in FIG. 4, the process is performed in accordance with an instruction signal from the PC 9 provided in the desk 82 (A) or the PC 9 provided in the desk 82 (B). Is called. Similarly, in the process for the partition 19 (AC), the process is performed in accordance with an instruction signal from the PC 9 provided on the desk 82 (A) or the PC 9 provided on the desk 82 (C). In other words, the image forming apparatus 1 forms the processing target partition 19 or cancels the formation of the processing target partition 19 according to a signal from the PC 9 provided on the desk 82 used for visual field shielding. Therefore, the partition 19 (AB) positioned between the desk 82 (A) and the desk 82 (B) forms an image from at least one of the PCs 9 provided on each of the desks 82 (A, B). While the instruction signal is periodically transmitted to the device 1, the formed state is maintained. On the other hand, the dedicated partition 19 (A) for the desk 82 (A) is formed or released only in response to an instruction signal from the PC 9 provided on the desk 82 to the image forming apparatus 1.

  In subsequent S112, the control unit 97 determines whether or not a setting change operation for changing the setting of the display mode of the partition 19 has been performed by the user 81 of the PC 9. That is, the dedicated software described above has a function of allowing the user 81 to change various settings relating to the formation of the partition 19. Specifically, the user 81 uses the PC 9 to, for example, the height, width, shape, transparency, display pattern, display color, and various set times (for example, the set time T1 described above and the set time described later). Settings such as T2) can be changed. Note that when the user 81 of the different desk 82 makes different settings for the same partition 19, any one setting is adopted by the image forming apparatus 1 according to a predetermined priority. For example, priority may be given to the setting with the higher visibility shielding property, and for example, the user (for example, the boss) with the higher priority may be given priority.

  If the control unit 97 determines that the setting change operation has been performed in S112, the control unit 97 shifts the process to S113, and sets the setting information indicating the setting changed by the user 81 via the communication unit 96. Then, the process proceeds to S114. As a result, the image forming apparatus 1 performs processing that reflects the changed settings.

On the other hand, when determining in S112 that the setting change operation has not been performed, the control unit 97 skips S113 and shifts the process to S114.
In S <b> 114, the control unit 97 determines whether or not a release operation for releasing the formation of the partition 19 has been performed by the user 81 of the PC 9. In other words, the dedicated software described above has a function of enabling the partition 19 to be released at an arbitrary timing desired by the user 81.

  If the control unit 97 determines in S114 that the release operation has been performed, the control unit 97 shifts the processing to S115. In S115, the control unit 97 determines whether or not the forming operation for re-forming the partition 19 has been performed by the user 81 of the PC 9, and when it is determined that the forming operation has been performed, the process proceeds to S116. Let That is, after the release operation is performed, the control unit 97 waits until the formation operation is performed. During this waiting period, the transmission of the instruction signal is stopped, and as a result, the formation of the partition 19 is released. However, when an instruction signal is transmitted from another PC 9 that uses the same partition 19, formation of the partition 19 is not released. Note that the formation of the partition 19 may be forcibly canceled by an instruction from one of a plurality of PCs 9 using the same partition 19.

On the other hand, when determining in S114 that the release operation has not been performed, the control unit 97 skips S115 and shifts the process to S116.
In S116, the control unit 97 determines whether or not the non-detection state of the user 81 by the camera 93 has continued for a set time T2 (for example, 1 minute). That is, the dedicated software described above has a function of constantly detecting the presence / absence of the user 81 of the PC 9 by analyzing an image taken by the camera 93.

  When the control unit 97 determines in S116 that the non-detection state of the user 81 (the state in which the user 81 does not exist) continues for the set time T2, the control unit 97 shifts the process to S117. In S117, the control unit 97 determines whether or not the user 81 has been detected by the camera 93. When it is determined that the user 81 has been detected, the control unit 97 returns the process to S111. That is, after the non-detection state of the user 81 continues for the set time T2, the control unit 97 waits until the user 81 is detected again. During this waiting period, the transmission of the instruction signal is stopped, and as a result, the formation of the partition 19 is released. However, when an instruction signal is transmitted from another PC 9 that uses the same partition 19, formation of the partition 19 is not released. Note that the partition 19 may not be formed when the number of users 81 who use the same partition 19 is one or less.

  On the other hand, if it is determined in S116 that the non-detected state of the user 81 has not continued for the set time T2, the control unit 97 skips S117 and returns the process to S111. In addition, an instruction | indication signal is periodically transmitted by returning a process to S111 regularly (repetitively).

  Next, image forming processing executed by the control unit 16 of the image forming apparatus 1 will be described with reference to the flowchart of FIG. The image forming process is started when the image forming apparatus 1 is turned on. Also, the image forming process is executed independently for each partition 19 in a state where the image forming process is divided into a plurality of parts as shown in FIG.

  First, in S121, the control unit 16 determines whether or not an instruction signal (specifically, an instruction signal from one or more PCs 9 that use the partition 19 to be processed) is received from the PC 9, and is received. When the determination is made, the process proceeds to S122. That is, after starting the image forming process, the control unit 16 stands by until an instruction signal is received. During this standby, the partition 19 to be processed is not formed. Note that the PC 9 that is the transmission source of the instruction signal is identified based on the identification information included in the instruction signal.

  In subsequent S122, the control unit 16 forms the partition 19 to be processed. Specifically, a visible image is formed by driving the laser light source 11, the scanning unit 12, and the driving unit 14 according to the current settings (height, width, shape, degree of transmission, display pattern, display color, etc.).

  In subsequent S123, the control unit 16 determines whether or not setting information (information transmitted from the PC 9 in S113 described above) has been received. If it is determined in S123 that the setting information has been received, the control unit 16 shifts the process to S124, changes various settings related to the formation of the partition 19 according to the received setting information, and then moves the process to S125. Transition. On the other hand, when determining in S123 that the setting information has not been received, the control unit 97 skips S124 and shifts the process to S125.

  In S125, the control unit 16 determines whether or not the instruction signal non-reception state has continued for the set time T1. If the control unit 16 determines in S125 that the non-reception state of the instruction signal does not continue for the set time T1 (in other words, the instruction signal is periodically received), the process proceeds to S123. return. As described above, the process is repeatedly returned to S123, thereby maintaining the state in which the partition 19 is formed.

  On the other hand, if it is determined in S125 that the non-reception state of the instruction signal has continued for the set time T1, the control unit 16 shifts the process to S126 and cancels the formation of the partition 19 to be processed (partition 19 After deleting, the process returns to S121.

<Effect>
According to the first embodiment described in detail above, the following effects can be obtained.
The visual field can be blocked without using a physical member such as a plate.

  Compared with the partition using a physical member, switching of installation / removal can be performed simply. For example, it is possible to easily switch between an environment for the user 81 to concentrate on individual tasks and an environment for a plurality of users 81 to have a discussion.

Compared with the partition using a physical member, ventilation is good and an air-conditioning effect can be made high.
Compared with a partition using a physical member, the sound can be improved.

The formation of the partition 19, the change of the formation mode, the release of the formation, and the like can be performed in the form of arbitrating the intentions of different users 81.
The formation and release of the partition 19 are linked to the PC 9, so that it is not necessary to provide a dedicated operation unit.

  The partition 19 is formed when the power of the PC 9 is turned on, and the formation is canceled when the power of the PC 9 is turned off. Therefore, the operation burdened by the user 81 can be reduced. It can be made difficult to forget.

The degree of transparency of the partition 19 can be changed. For this reason, it is also possible to set the degree of transmission to such an extent that the presence of the user 81 can be confirmed but the line of sight is difficult to feel.
Since the image forming apparatus 1 is provided on the ceiling 84, an extra space is not required, and the laser beam can be hardly blocked by the user 81 or the like.

<Modification>
The first embodiment is merely one configuration example, and may be configured as follows, for example.

You may provide the operation part for exclusive use which performs operations, such as formation of a partition and formation cancellation | release.
The user 81 may be detected by a detection unit other than the camera 93. The detection unit is not limited to diverting the configuration of the PC 9 or the like, and may be provided exclusively.

The configuration of the PC 9 may not be diverted and may be configured by the image forming apparatus 1 alone.
You may form so that the perimeter may be enclosed in the form which does not provide the entrance / exit of the user 81. Moreover, you may make it open and close an entrance / exit.

A single partition 19 is not limited to being used by a plurality of users, and a dedicated partition 19 may be formed for each user 81.
The partition 19 itself may function as a display.

A dummy figure or the like may be displayed on the partition 19.
In order to improve the performance of blocking the view, the partition 19 may be formed in a plurality of layers.

A plurality of laser light sources 11 may be provided in one image forming apparatus 1.
Smoke, mist, or the like may be used in combination to prevent the tip of the partition 19 from being seen through.

One partition 19 may be formed by a plurality of image forming apparatuses 1.
The emission direction of the laser beam is not limited from above, and is not particularly limited from below, from the lateral direction, from the oblique direction, and the like. Moreover, you may make it radiate | emit from several directions.

The environment in which the partition 19 is used is not limited to the office, and may be used in, for example, a library, a restaurant, a test venue, a vehicle (for example, a train or an airplane), and the like.
The application of the visible image that blocks the view is not limited to the partition 19. For example, a simple changing room may be formed. If it does in this way, it will become possible not to ensure the exclusive space as a changing room. In addition, a sensor that detects the approach or passage of the visible image may be provided, and notification (output of sound, change of display mode, or the like) may be performed according to the detection result.

  Further, for example, a visible image may be formed instead of a curtain or a blind in a house. In addition, a visible image may be formed in order to make the veranda and the rooftop space less visible from the outside. In such applications, effects such as easy installation / removal switching and good ventilation are particularly effective.

  Further, for example, in an automatic teller machine (ATM), a visible image that prevents peeping by other users may be formed. The visible image may display content (confusing content) that makes it difficult to grasp information that is not desired to be seen through the visible image, such as meaningless numbers.

[Second Embodiment]
<Configuration>
As shown in FIG. 6, FIG. 7A and FIG. 7B, the appearance changing system of the second embodiment is mounted on a vehicle and covers the original body 69 of the vehicle as a pseudo image (hereinafter “ ("Virtual body") 29, and includes a plurality of image forming apparatuses 2 and an operation device 7. The virtual body 29 is a visible image that can be visually recognized from the outside as the appearance of the vehicle, and is an enlargement of the original body 69. The virtual body 29 may be of the same vehicle type or of different vehicle types. There may be.

  As shown in FIGS. 7A and 7B, the image forming apparatus 2 is set at a plurality of locations of the vehicle. In the present embodiment, the image forming apparatuses 2A, 2B, 2B, 4B are located at the front center position and the left and right side positions, the left and right door mirror tip positions, the front surface front center position and the left and right side positions, the top rear surface center position, and the rear center position. 2C, 2D, 2E, 2F, 2G, 2H, 2I, and 2J are provided.

  As shown in FIG. 6, each image forming apparatus 2 includes a laser light source 11, a scanning unit 12, a condenser lens 13, a driving unit 14, a communication unit 25, and a control unit 16. Among these, the laser light source 11, the scanning unit 12, the condenser lens 13, the driving unit 14, and the control unit 16 have the same functions as those in the first embodiment, and thus description thereof is omitted. The communication unit 25 is a communication device for performing data communication with the operation device 7 via a communication line mounted on the vehicle.

The operation device 7 includes an operation unit 71, a communication unit 72, and a control unit 73.
The operation unit 71 is an input device for inputting a command by an external operation from a user (for example, a driver) who gets on the vehicle, and is provided in the interior of the vehicle (for example, a position where the driver can operate during driving). ing.

The communication unit 72 is a communication device for performing data communication with each of the plurality of image forming apparatuses 2 via a communication line mounted on the vehicle.
The control unit 73 performs overall control of each unit of the operation device 7 and includes a CPU, a ROM, a RAM, and the like.

<Processing>
Next, processing executed in the appearance change system of this embodiment will be described.
First, the reason executed by the control unit 73 of the controller device 7 will be described.

  The control unit 73 transmits a formation signal to each image forming apparatus 2 via the communication unit 72 when an operation for forming the virtual body 29 is performed by the user through the operation unit 71. The formation signal is a signal for causing the image forming apparatus 2 to form the virtual body 29. As will be described later, the image forming apparatus 2 forms the virtual body 29 when the formation signal is received.

  For example, as shown in FIGS. 7A and 7B, the virtual body 29 is formed by being shared by a plurality of image forming apparatuses 2. Note that the number and arrangement of the image forming apparatuses 2 illustrated in FIGS. 7A and 7B are merely examples, and the present invention is not limited thereto.

  On the other hand, when an operation for canceling the formation of the virtual body 29 is performed by the operation unit 71 by the user, the control unit 73 transmits a cancel signal to each image forming apparatus 2 via the communication unit 72. The release signal is a signal for causing the image forming apparatus 2 to release the formation of the virtual body 29. As will be described later, the image forming apparatus 2 cancels the formation of the virtual body 29 when the release signal is received.

Next, image forming processing executed by the control unit 16 of the image forming apparatus 2 will be described with reference to the flowchart of FIG.
First, in S211, the control unit 16 determines whether or not a formation signal has been received from the controller device 7. When it is determined that the formation signal has been received, the control unit 16 shifts the processing to S212. That is, after starting the image forming process, the control unit 16 waits until a formation signal is received. During this standby, the virtual body 29 is not formed.

  In S212, the control unit 16 forms the virtual body 29. Specifically, a preset visible image (visible image representing the appearance of a pseudo vehicle) is formed by driving the laser light source 11, the scanning unit 12, and the driving unit 14.

  In subsequent S213, the control unit 16 determines whether or not a release signal is received from the controller device 7. When it is determined that the release signal is received, the control unit 16 shifts the processing to S214. That is, after forming the virtual body 29, the control unit 16 waits until a release signal is received. During this standby, the state in which the virtual body 29 is formed is maintained.

In S214, the control unit 16 cancels the formation of the virtual body 29 (deletes the virtual body 29), and then returns the process to S211.
<Effect>
According to the second embodiment described in detail above, the following effects can be obtained.

The field of view of the original appearance (body 69) of the vehicle can be blocked without using a physical member.
It is also possible to prevent the interior of the vehicle from being removed by covering the window portion.

  Scratches and dirt on the original vehicle body 69 can be hidden by the virtual body 29. Further, since an external appearance (for example, an external appearance of a different vehicle model) different from the body 69 of the original vehicle can be formed, for example, an old model vehicle can be shown as if it was the latest model.

Compared with the case where the appearance is covered using a physical member, it is possible to easily switch between a state where the appearance is covered and a state where the appearance is not covered.
Since there is no air resistance as compared with the case where the appearance is covered using a physical member, it is possible to make it difficult to affect the running.

<Modification>
The second embodiment is merely one configuration example, and may be configured as follows, for example.

  The formation and release of the virtual body 29 may be automatically performed according to the traveling environment (for example, weather, surrounding environment, etc.) of the vehicle, the driving situation (for example, traveling speed, etc.), and the like. In addition, the formation mode of virtual body 29 (shape, color, pattern change mode that changes with time) and the like may be changed according to such a driving environment and driving conditions.

  A plurality of types of modes may be used as the virtual body 29. For example, the data of the virtual body 29 may be downloaded from a server. In this way, the virtual body 29 representing the appearance of the latest model can be easily obtained and used.
