  2. Description of the Related Art Conventionally, there has been known an image projection apparatus that projects a still image, a moving image, and an image created by a personal computer or the like on a projection surface such as a screen in a presentation or a meeting. There is also known an image projection system that includes an image projection device and a remote operation device that can be remotely controlled to turn on / off the power of the image projection device and various projection settings and is easy to carry.

  In the image projection system as described above, various types of image projection apparatuses are installed so that an optimum image can be projected at an intended projection position within a projectable range in a room such as a conference room where image projection is performed. Conventionally, it has been a problem to easily adjust projection settings quickly. This problem is related to the proficiency level of the user who installs the image projection apparatus (hereinafter referred to as an operator) with respect to the operation of the image projection apparatus to be used and the proficiency level of the room where the image projection apparatus is installed (degree of installation experience) Often affected. However, the level of proficiency of the operator with the image projection device to be used and the room in which the operator is installed is not always high. Also, even in the same image projection device or room, the optimal projection position differs depending on the layout of the seat etc., so even an operator who is highly proficient in the image projection device to be used and the room in which it is installed In some cases, it takes time to adjust various projection settings during installation.

  Patent Document 1 describes the configuration of an image projection system including the following image projection apparatus (projector) and a remote operation apparatus (remote control) capable of remotely controlling various projection settings of the image projection apparatus. . The image projection apparatus includes a projection size adjustment unit (zoom function) for enlarging / reducing the size of a projection image projected onto a projection surface, and a communication unit with a remote control device. In addition, the remote control device includes an operation unit that operates a projection size adjustment unit of the image projection device, and a communication unit that communicates with the image projection device. The remote control device also includes guide image irradiating means for irradiating (projecting) a guide image (screen) having a size equal to the size of the projection image on the projection surface (screen) by the image projection device. . The guide image irradiated by the guide image irradiating means indicates a guide for the position and size of the projected image on the projection surface to the operator.

Prior to the installation of the image projection apparatus, the operator moves the remote operation apparatus while irradiating the projection surface with the guide image on the projection surface, so that the guide image has a suitable position and image size on the projection plane. The position of the remote control device and the adjustment amount of the zoom adjustment means are determined. Thus, after determining the position of the remote control device and the adjustment amount of the zoom adjustment means, the operator installs the image projection device at the determined position of the remote control device.
As described above, by determining a suitable installation position of the image projection device and an adjustment amount of the zoom adjustment means of the image projection device with the remote operation device as described above, the operator can easily install the image projection device.

The image projection device includes a projection posture detection unit that detects a horizontal posture of the image projection device, and an optical axis posture adjustment unit that adjusts a horizontal posture of the optical axis with respect to the reference axis. Remote The operation device includes: a remote device posture detection unit that detects a horizontal posture of the remote control device; and the projection of the projection image that is projected by the image projection device from the guide image irradiated by the guide image irradiation unit. An irradiation layout selection means for selecting an area on the surface; and a storage means for storing a detection result of the remote device posture detection means when the guide image is irradiated to the area selected by the irradiation layout selection means. The projection setting calculation unit is configured to set the left and right projection optical axis setting values based on the detection result of the remote device posture detection unit and the detection result of the projection posture detection unit stored in the storage unit of the remote operation device. And the image projection device sets the horizontal orientation of the optical axis by the optical axis orientation adjustment means based on the left and right projection optical axis setting values calculated by the projection setting calculation means. It is characterized in that integer.

  In the present invention, the optical axis posture adjusting means can automatically adjust the horizontal posture of the optical axis of the image projection apparatus based on the left and right projected optical axis setting values calculated by the projection setting calculating means. Therefore, it is possible to adjust the horizontal orientation of the optical axis of the image projection apparatus more easily and in a shorter time than the configuration in which the horizontal orientation of the optical axis of the image projection apparatus is set visually.

The terminal 301 will be briefly described as an example.
The six-axis sensor and the geomagnetic sensor included in the detection unit 360 of the portable information terminal 301 are used to determine the vertical orientation (pitch) and the horizontal orientation (yaw) of the orthogonal coordinate system, which is the dynamic coordinate system of the portable information terminal 301. ), And the rotation posture (roll) around the reference axis can be detected. Further, the azimuth angle of the reference axis (the direction of the front surface of the portable information terminal 301) and the angle formed by the reference axis and the vertical axis can also be detected. Then, by using the Euler angle and the orthogonal coordinate system of the dynamic coordinate system and the stationary coordinate system, the rotation angle, that is, the attitude (tilt) with respect to each axis in the orthogonal coordinate system (Xn-Yn-Zn) of the predetermined stationary coordinate system. Can be detected (calculated). Here, the predetermined orthogonal coordinate system (Xn-Yn-Zn) can be changed according to a value calculated by the projector remote software installed in the portable information terminal 301, and is based on the portable information terminal 301 main body. Can be converted from the orthogonal coordinate system (Xs-Ys-Zs) of the dynamic coordinate system.

The Zs axis of the Cartesian coordinate system (Xs-Ys-Zs) of the dynamic coordinate system with the portable information terminal 301 as a reference is an axis perpendicular to the touch panel display 311 and passing through the center thereof. Further, the upper side of the touch panel display 311 is set as the positive direction of the Zs axis, and the rotation angle around the Zs axis is the yaw angle, that is, the posture in the left-right direction.
The Ys axis is an axis perpendicular to the Zs axis and passing through the center of the left side surface and the right side surface of the portable information terminal 301 main body. Further, when the touch panel display 311 is directed upward, the direction from the left side surface to the right side surface is defined as the positive direction of the Ys axis, and the rotation angle around the Ys axis is defined as the pitch angle, that is, the vertical posture.

Further, when the touch panel display 311 is directed upward, the direction from the rear surface to the front surface is the positive direction of the Xs axis, and the rotation angle around the Xs axis is the roll angle, that is, around the reference axis of the portable information terminal 301 main body. Rotating posture.

  Note that, similarly to the portable information terminal 301, the projector 100 has an orthogonal coordinate system (Xp-Yp-Zp) of a dynamic coordinate system based on the projector 100 main body. The Zp axis is an axis perpendicular to the upper surface excluding the protrusion and passing through the center thereof, and the upper side is the positive direction of the Zp axis. The Yp axis is an axis perpendicular to the Zp axis and the reference axis Lpb0 of the projector 100, and the direction from the left side to the right side when the liquid crystal display 111 is directed upward is the positive direction of the Yp axis.

It is explanatory drawing of the guide image 2 which illustrates and superimposes and irradiates.

  First, in order to clarify the operation and effect of the image projection system 700 of the present embodiment, problems of the conventional image projection system will be described. In a conventional image projection system, a projection layout including the position of a projector capable of projecting a projected image at the intended position and size on the projection surface and the attitude of the projection optical axis is determined in a venue such as a conference room where the image is projected. It may take time to install. Such a problem has arisen for the following reason.

  The time required to determine and install the projection layout often depends on the level of proficiency of the operator who installs the projector and the level of the site where the projector is installed. However, the operator is not always proficient in the projector to be used and the installation site. Even in the same projector or venue, the optimal projection position differs depending on the layout of the seats, etc., so even a highly skilled operator at the projector or installation venue will be It may take time to adjust various projection settings of the projector.

  More specifically, the projection layout depends on the layout of the venue, such as the size of the venue, the number of participants in the conference, the layout of the seats, etc., but at the stage of installing the projector for the first time, the layout in the venue is known. It ’s hard. In addition, it is difficult to understand the image when the participant actually sits down, and it is difficult for many participants to see where the projected image is projected on the projection surface. In addition, if it is a projector that is used for the first time, the setting method of the projection setting is unknown. Even if the projector has been used several times, if the venue is different, the projection layout is lost and it takes time to determine the projection layout. Furthermore, although it is desired to set the projection setting while confirming the projection image on the projection surface, in recent years, there are many projectors that can automatically adjust the projection setting such as trapezoidal distortion correction, and there are cases where the projection cannot be performed at the intended position and size.

  The reason why it may take time after the projection layout is determined and the projector is installed is as follows. Because the projected image looks different depending on the seating position in the venue, I want to fine-tune the height and tilt of the projector after installing it once and checking the appearance after sitting in multiple seats. It is often installed and its readjustment is troublesome. Depending on the determined projection layout, the operator may have to manually readjust the height of the projector while viewing the projection screen projected onto the projection surface. The hands to adjust are separate and difficult to adjust.

  In the image projection system described in Patent Document 1, a configuration is described in which a remote operation device is provided with guide image irradiation means for irradiating a projection surface with a guide image to determine the position and size of the projection image. However, as described above, it is necessary for the operator to store the attitude of the remote control device when the position and size of the projection image are determined, and to install the projector based on the storage. For this reason, there is a high possibility that the right-and-left orientation is displaced and it takes time to adjust the orientation of the projector optical axis: Lpn in the left-right direction. Specifically, the arrangement of the projector and the irradiation of the guide image are repeated until a suitable projection image position is obtained, or the left and right directions of the pyrojector are determined based on the storage of the position of the selected guide image on the projection surface 11. The position adjusting means is adjusted. As a result, it takes time to install the projector, that is, to determine the projection layout.

Therefore, in this embodiment, the determination of the projection layout when installing the projector 100 and the various projection settings of the projector 100 based on the determined projection layout are performed as follows.
As described above, the portable information terminal 301 having the irradiation unit 330 that functions as a guide image irradiation unit is used as the remote operation device 300 that remotely operates the projector 100. As shown in FIG. 1, the irradiation unit 330 irradiates the projection surface 11 with a guide image 2 that indicates an indication of the position and size of the projection image 1 projected onto the projection surface 11 by the projector 100. Further, the posture (tilt) of the irradiation optical axis: Lsn passing through the diagonal center of the guide image 2 to be irradiated with respect to the reference axis: Lsb0 passing through the center of the front and rear surfaces of the main body portion of the portable information terminal 301 is adjusted. Is possible. However, in the initial setting, as shown in FIG. 5B, the optical axis: Lsn from the irradiation unit 330 passing through the diagonal center of the guide image 2 is configured to be parallel to the reference axis: Lsb0. In the following description, the optical axis from the default irradiation unit 330 is referred to as a reference optical axis: Ls0.

  In addition, the guide image 2 irradiated from the irradiation unit 330 of the portable information terminal 301 is subjected to the following guide image 2 by pressing either the operation button or the operation button 314 displayed on the touch panel display 311. Irradiation onto the projection surface 11 is possible. A guide image 2 having the same position and the same size as the outline of the projection image 1 when projected from the projector 100 onto the projection surface 11 at the same position and the same projection posture (irradiation posture) is displayed on the projection surface 11. Can be irradiated. Also, a rectangle based on the information on the correction range that can be corrected by the optical axis posture adjusting unit, the projection size adjusting unit, and the projection trapezoidal distortion correcting unit of the projector 100 from the image projection system management database, and the position information of the projection surface 11. The guide image 2 can also be irradiated onto the projection surface 11.

  Then, the portable information terminal 301 generates a guide image 2 to be applied to the projection image 1 projected by the projector 100 from the candidates for the guide image 2 irradiated on the projection surface 11 while moving the portable information terminal 301 main body. Irradiation layout selection means for selecting is provided. This irradiation layout selection means selects a region on the projection surface 11 of the projection image 1 projected by the projector 100 from the candidates of the guide image 2 that is projected onto the projection surface 11 while moving the portable information terminal 301 main body. It is for selection. The irradiation layout selection means is configured to be selected by pressing either the operation button 314 or the operation button 314 of the portable information terminal 301 or pressing the operation button displayed on the touch panel display 311. it can. Further, the portable information terminal 301 may be configured to be selected by holding the posture and position of the portable information terminal 301 for a certain time (several seconds).

In addition, the detection result of the position and orientation of the portable information terminal 301 detected by the remote device attitude detection unit of the detection unit 360 when selected by the irradiation layout selection unit is temporarily stored in the RAM of the storage unit 402 of the control unit 400. Thereafter, it is stored in a nonvolatile memory 405 as a storage means.
Further, the projection apparatus remote software installed in the portable information terminal 301 calculates the adjustment amount of the posture of the projection optical axis: Lpn passing through the diagonal center of the target projection image 1 with respect to the reference axis: Lp0 of the projector 100. To do. That is, the projection setting calculation means for calculating the adjustment amount of the attitude of the projection optical axis: Lpn with respect to the reference axis: Lp0 is realized by the projector remote software installed in the portable information terminal 301. In the present embodiment, a configuration in which the portable information terminal 301 includes the projection setting calculation unit will be described. However, the present invention is not limited to such a configuration, and the projector 100 and the database server 510 are provided. You may provide a projection setting calculation means.

  Further, the portable information terminal 301 can acquire information relating to the projection layout of the past projector 100 from the database server 510 as information on the recommended projection layout, and display the projection layout on the touch panel display 311. In this manner, difference information calculation means for calculating difference information between the position and orientation of the arranged projector 100 and the recommended projection layout when the projection layout of the touch panel display 311 is displayed is also provided. By displaying the result calculated by the difference information calculation unit on the touch panel display 311, the re-installation (position and orientation) of the projector 100 can be easily performed. Also, once the projection layout is determined in advance, the installation work can be facilitated even when the projector 100 is installed later.

  In the image projection system management database, information on the longitude, latitude, and altitude of the four corners of each projection surface 11 is stored as the projection condition information, and the position and orientation information of the projection surface 11 that can be projected in the venue 10. ing. In addition, information on an adjustment range that can be adjusted by the optical axis attitude adjustment unit of the projector 100, information on an adjustment range that can be adjusted by the projection size adjustment unit, and information on a correction range that can be corrected by the projection trapezoidal distortion correction unit are also stored. .

  Next, a plurality of specific examples will be given regarding the installation of the projector 100 and the adjustment of the projection optical axis: Lpn of the projector 100, which are performed based on the guide image 2 selected by the irradiation layout selection unit of the portable information terminal 301. explain.

Further, the irradiation optical axis: Lsn of the guide image of the portable information terminal 301 when the guide image 2 is irradiated is assumed to be the reference optical axis: Ls0.

  As shown in FIG. 9B, the height (Zn) at which the projector 100 is installed and the vertical orientation (horizontal) from the time when the portable information terminal 301 irradiates the guide image 2 with reference to the table 12. The guide image 2 to be applied to the projection image 1 is selected in consideration of the above. In this case, the planar position (Xn, Yn) of the portable information terminal 301 and the horizontal orientation are excluded from the operator's memory, excluding the vertical orientation (horizontal) when the selected guide image 2 was irradiated. Based on this, the projector 100 is arranged. Then, as shown in FIGS. 9A and 9C, the plane position can be appropriately arranged because it is easy to use the table 12 as a reference, but the right and left posture is easily shifted.

  In the image projection system 700 according to the present embodiment, as described above, both the portable information terminal 301 and the projector 100 can detect their horizontal postures, and can acquire the other detection result using communication means. it can. Therefore, based on the detection result in the horizontal direction of the projection posture detection means and the detection result in the horizontal direction stored in the storage means of the portable information terminal 301, the adjustment amount Δψ in the horizontal direction of the projector 100 is calculated by the projection setting calculation means. calculate. Then, the control button 314 of the display / operation unit 310 is operated to transmit a control signal for applying the calculation result to the projector 100. The projector 100 projects the projection light on the projection optical axis: Lpn in which the set value is adjusted by the adjustment amount Δψ in the horizontal direction from the reference optical axis: Lp0 by the optical axis attitude adjustment means according to the received control signal based on the value of the adjustment amount Δψ. Adjust the axis posture. Then, the projection image 1 from the projector 100 is at the same position on the projection surface as the guide image 2 selected by the portable information terminal 301 as shown in FIGS. 9 (d), (e), and (f). The projection image 1 ′ is projected.

With the configuration described above, image projection that can easily adjust the horizontal position of the projection optical axis: Lpn of the projector 100 that projects onto the projection surface 11 and can reduce the time required for the installation of the projector 100 by the operator. A system 700 can be provided.
Further, when installing the projector 100, the image projection onto the projection surface 11 by the projector 100 is not necessarily performed at the time of installation. For example, after selecting the guide image 2 on the projection surface 11 with the portable information terminal 301, the projector 100 is arranged based on the memory of the operator, and the projection mechanism unit 130 and the intake / exhaust unit are turned on when the main power is turned on. The power supply of each part other than 170 can be turned on. By performing the installation in this way, the reference beam is adjusted by the optical axis posture adjusting unit of the projector 100 without projecting a projection image on the projection surface 11 using the projection mechanism unit 130 and the intake / exhaust unit 170 that consumes a large amount of power. Axis: The set value can also be adjusted from Lp0 by the adjustment amount ΔΨ.
Further, with respect to the posture value detected by the remote device posture detection unit of the portable information terminal 301 and the projection posture detection unit of the projector 100, an orthogonal coordinate system based on the vertical and azimuth at a certain point is used from the dynamic coordinate system. Coordinate conversion to (Xn-Yn-Zn) can also be used.

(Specific example 2: Vertical posture)
The vertical projection optical axis of the projector 100 based on the detection result of the attitude of the portable information terminal 301 when the guide image 2 is selected and the detection result of the attitude of the projector 100 installed at the position of the portable information terminal 301 : Adjustment of Lpn will be described with reference to FIG.
10A is an explanatory diagram of the guide image 2 on the projection surface and the projection image 1 before adjustment. FIG. 10B is a side explanatory diagram of the guide image 2 and the projection image 1 before adjustment. 10 (c) is an explanatory plan view of the guide image 2 and the projection image 1 before adjustment. FIG. 10D is an explanatory diagram of the guide image 2 on the projection surface and the adjusted projection image 1. FIG. 10E is a side explanatory diagram of the guide image 2 and the adjusted projection image 1. FIG. (F) is a plane explanatory view of the guide image 2 and the projection image 1 after adjustment.

  For example, the horizontal table 12 shown in FIG. 1 is arranged so that the center line is perpendicular to the vertical projection surface 11, the image is projected along the center line, and the vertical direction with respect to the projection surface 11. Assume that the projected image 1 is projected in a posture in which the angle is inclined. Other conditions are the same as in the description of the adjustment of the projection optical axis Lpn in the horizontal direction of the projection image 1 described above.

  As shown in FIGS. 10B and 10C, when the portable information terminal 301 emits the guide image 2, the height at which the projector 100 is installed and the posture in the left-right direction are considered with reference to the table 12. The guide image 2 to be applied to the projection image 1 is selected. In this case, the operator determines the planar position and the vertical orientation of the portable information terminal 301 excluding the horizontal orientation (the direction along the center line of the table 12) when the selected guide image 2 is irradiated. Based on this storage, the projector 100 is arranged. Then, as shown in FIGS. 10A and 10B, the arrangement position can be appropriately arranged because it is easy to use the table 12 as a reference, but the vertical posture is easily shifted.

  In the image projection system 700 of the present embodiment, as described above, both the portable information terminal 301 and the projector 100 can detect their own vertical postures, and can acquire the other detection result using communication means. it can. Therefore, based on the detection result in the vertical direction of the projection posture detection means and the detection result in the vertical direction stored in the storage means of the portable information terminal 301, the adjustment amount Δθ in the vertical direction of the projector 100 is calculated by the projection setting calculation means. calculate. Then, the control button 314 of the display / operation unit 310 is operated to transmit a control signal for applying the calculation result to the projector 100. The projector 100 projects the projection light on the projection optical axis: Lpn in which the set value is adjusted by the adjustment amount Δθ in the vertical direction from the reference optical axis: Lp0 by the optical axis attitude adjustment means according to the received control signal based on the value of the adjustment amount Δθ. Adjust the axis posture. Then, the projection image 1 from the projector 100 is at the same position on the projection surface as the guide image 2 selected by the portable information terminal 301, as shown in FIGS. 10 (d), (e), and (f). The projection image 1 ′ is projected.

With the configuration described above, image projection that can easily adjust the vertical position of the projection optical axis: Lpn of the projector 100 that projects onto the projection surface 11 and can reduce the time required for the installation of the projector 100 by the operator. A system 700 can be provided.
In addition, the other actions and effects described in the specific example 1 can be obtained in the same manner.

(Specific example 3: Vertical and horizontal postures)
Based on the detection result of the attitude of the portable information terminal 301 when the guide image 2 is selected and the detection result of the attitude of the projector 100 installed at the position of the portable information terminal 301, projection in the vertical and horizontal directions of the projector 100 is performed. Adjustment of the optical axis: Lpn will be described with reference to FIG.
11A is an explanatory diagram of the guide image 2 on the projection surface and the projection image 1 before adjustment. FIG. 11B is a side explanatory diagram of the guide image 2 and the projection image 1 before adjustment. 11 (c) is an explanatory plan view of the guide image 2 and the projection image 1 before adjustment. 11D is an explanatory diagram of the guide image 2 on the projection surface and the adjusted projection image 1. FIG. 11E is a side explanatory diagram of the guide image 2 and the adjusted projection image 1. FIG. (F) is a plane explanatory view of the guide image 2 and the projection image 1 after adjustment.

  For example, the vertical and horizontal angles with respect to the projection surface 11 are set so that an image is projected from an arbitrary point on the horizontal table 12 shown in FIG. 1 to an arbitrary projection position on the vertical projection surface 11. Assume that the projected image 1 is projected in an inclined posture. Other conditions are the same as in the description of the adjustment of the projection optical axis: Lpn in the horizontal direction and the vertical direction of the projection image 1 described above.

  As shown in FIGS. 11B and 11C, when the portable information terminal 301 irradiates the guide image 2, the projection image is irradiated with the height at which the projector 100 is installed taking the table 12 as a reference. A guide image 2 to be applied to 1 is selected. In this case, the projector 100 is arranged based on the memory of the operator regarding the planar position, the vertical orientation, and the horizontal orientation of the portable information terminal 301. Then, as shown in FIGS. 11 (a), 11 (b), and 11 (c), the arrangement position can be appropriately arranged because it is easy to use the table 12 as a reference, but the vertical posture and the horizontal posture are misaligned. easy.

  In the image projection system 700 of this embodiment, as described above, both the portable information terminal 301 and the projector 100 can detect their own vertical and horizontal orientations, that is, the vertical and horizontal orientations, and mutually communicate using communication means. The other detection result can be acquired. Therefore, based on the detection results in the vertical and horizontal directions of the projection posture detection unit and the detection results in the vertical and horizontal directions stored in the storage unit of the portable information terminal 301, the projection setting calculation unit calculates the vertical direction of the projector 100. An adjustment amount Δθ and an adjustment amount Δψ in the left-right direction are calculated. Then, the control button 314 of the display / operation unit 310 is operated to transmit a control signal for applying the calculation result to the projector 100. In accordance with the control signal based on the received adjustment amount Δθ and the adjustment amount Δψ, the projector 100 sets the adjustment amount Δθ in the vertical direction and the adjustment amount Δψ in the horizontal direction from the reference optical axis Lp0 by the optical axis attitude adjustment unit. The projection optical axis whose value is adjusted: Lpn is adjusted to the attitude of the projection optical axis. Then, the projection image 1 from the projector 100 is at the same position on the projection surface as the guide image 2 selected by the portable information terminal 301, as shown in FIGS. 11 (d), 11 (e), and 11 (f). The projection image 1 ′ is projected.

With the configuration described above, it is possible to easily adjust the posture setting in the vertical direction in addition to the horizontal direction of the projection optical axis: Lpn of the projector 100 that projects onto the projection surface 11. Therefore, it is possible to easily adjust the horizontal and vertical orientations of the projection optical axis: Lpn of the projector 100 that projects onto the projection surface 11, and the time required for the installation of the projector 100 by the operator can be shortened.
Further, the other actions and effects described in the specific examples 1 and 2 described above can be obtained in the same manner.

(Specific example 4: Irradiating a guide image from a position different from the projector)
Next, the projection optical axes in the vertical and horizontal directions of the projector 100 when the portable information terminal 301 irradiates the projection surface 11 from a position different from (separated from) the installed projector 100: Lpn The adjustment will be described with reference to FIG. In this case, the portable information terminal 301 when the guide image 2 is selected, the detection result of the attitude and position of the installed projector 100, and information on the projection surface 11 in the vertical and horizontal directions of the projector 100. The projection optical axis: Lpn is adjusted.

  For example, an image is projected from an arbitrary point on the left side of the horizontal table 12 shown in FIG. 1 to an arbitrary projection position on the vertical projection surface 11 in the vertical and horizontal directions with respect to the projection surface 11. Assume that the projected image 1 is projected from the projector 100 in a posture in which the angle is inclined. Then, the guide image 2 is irradiated onto the vertical projection surface 11 from an arbitrary point on the right side of the table 12 to determine the projection position of the projection image 1 on the projection surface 11. At this time, the projection condition information stored in the image projection system management database is used in addition to the vertical and horizontal posture detection results of the portable information terminal 301 and the projector 100. Other conditions are the same as in the description of the adjustment of the projection optical axis: Lpn in the horizontal direction and the vertical direction of the projection image 1 described above.

As shown in FIGS. 12B and 12C, the projector 100 is first installed, and the portable information terminal 301 irradiates while moving the guide image 2 from a position different from the projector 100, and the projector 100 The position of the projection image 1 projected on the projection surface 11 is selected. Then, as shown in FIG. 12A, the position and size of the guide image 2 and the projection image 1 are different. Here, in addition to the optical axis orientation adjusting unit, the projector 100 of this specific example includes a projection size adjusting unit that adjusts the size of the projected image 1 and a projection trapezoidal distortion correcting unit that corrects the trapezoidal distortion of the projected image 1. I have.
When the guide image 2 is irradiated from different positions as described above, the projector is based on the position and size of the selected guide image 2 irradiated on the projection surface 11 and the detection result of the position and orientation of the projector 100. The next adjustment amount of 100 can be calculated. That is, the values of the vertical and horizontal adjustment amounts of the optical axis attitude adjustment unit, the adjustment amount of the projection size adjustment unit that adjusts the size of the projection image 1, and the projection trapezoidal distortion correction unit that corrects the trapezoidal distortion of the projection image 1. The amount of correction can be calculated.

The image projection system management database stores information on the longitude and latitude elevation of the four corners of each projection surface 11 as projection condition information. In addition, information on an adjustment range that can be adjusted by the optical axis attitude adjustment unit of the projector 100, information on an adjustment range that can be adjusted by the projection size adjustment unit, and information on a correction range that can be corrected by the projection trapezoidal distortion correction unit are also stored. .
Then, the portable information terminal 301 uses the irradiation posture detection means and the remote device position detection means to select the guide image 2 to be applied to the projection image 1 from the irradiated guide image 2, and It can detect the posture in the left-right direction and its own longitude, latitude, and altitude.
In addition, the projector 100 can detect the vertical and horizontal postures and the longitude, latitude, and altitude in its own moving coordinate system by the projection posture detection unit and the projection position detection unit.

  Therefore, in this specific example, the values of each moving coordinate system and the position information of the four corners of the projection surface 11 are coordinate-converted into a stationary coordinate system based on the vertical and azimuth angles at a certain point. In this specific example, the orthogonal coordinates are converted into an orthogonal coordinate system (Xn-Yn-Zn) with the Xn axis facing north and Yn facing east with reference to the vertical and azimuth at the base point position in the venue 10. The position on the projection surface 11 of the irradiation optical axis: Ls0 of the guide image 2 in the system is calculated. In this specific example, the diagonal center of the floor in the hall 10 is set as the base point position in the hall 10, but other points may be set as the base point positions.

  In addition, the portable information terminal 301 calculates the trapezoidal distortion of the guide image 2 based on the detection results of the positions and orientations of the portable information terminal 301 and the projector 100 and the following information stored in the storage unit of the portable information terminal 301. Irradiation trapezoidal distortion correction adjusting means for correcting is provided. The information includes the position information of the four corners of the projection surface 11 acquired from the image projection system management database, the information on the adjustment range that can be adjusted by the optical axis posture adjustment unit of the projector 100, and the information on the adjustment range that can be adjusted by the projection size adjustment unit. Further, it is information on a correction range that can be corrected by the projection trapezoidal distortion correcting unit of the projector 100. Further, based on the position information of the four corners of the projection surface 11 and the detection result of the position and orientation of the portable information terminal 301, the orientation of the reference optical axis: Ls0 with respect to the projection surface 11 to be irradiated is calculated. And it also has an irradiation size adjusting means for adjusting the size of the guide image 2 on the projection surface 11.

  As an operation method of the irradiation size adjusting means, a screen for adjusting the size may be displayed on the touch panel display 311 of the portable information terminal 301 for operation. Further, the portable information terminal 301 may be configured to be operated based on a detection result detected by the remote device position detection unit by changing (approaching or moving away) the distance from the projection surface 11 of the portable information terminal 301.

  First, in the portable information terminal 301, the projection surface 11 that irradiates the guide image 2 in the hall 10 is specified based on the horizontal posture (orientation) detected by the remote device posture detection means. Thereafter, based on the information on the correction range that can be corrected by the optical axis posture adjusting unit, the projection size adjusting unit, and the projection trapezoidal distortion correcting unit, and the posture of the reference optical axis Ls0 with respect to the projected surface 11, the projected surface 11 The guide image 2 corrected to a rectangle by the irradiation trapezoidal distortion correcting and adjusting means is irradiated on the top. Then, the operator moves the guide image 2 on the projection surface 11 and selects the guide image 2 to be applied to the projection image 1 while changing the size of the guide image 2 by the irradiation size adjusting unit. By selecting in this way, the guide image 2 that can be applied to the projection image 1 that can be projected from the position where the projector 100 is installed can be selected, and the projection image 1 is projected from the projector 100 at the same position and size as the guide image 2. Can be projected onto the projection surface 11. Further, unlike the specific examples 1 to 3, since the rectangular guide image can be projected on the projection surface 11, the actual projected image 1 can be easily imaged when determining the projection layout.

Further, in the storage unit of the portable information terminal 301, the detection result of the remote device attitude detection unit and the remote device position detection unit when the guide image 2 is selected, the adjustment amount of the irradiation size adjustment unit, and the irradiation trapezoidal distortion adjustment unit The correction amount is also stored.
Then, the projection setting calculation unit calculates the vertical and horizontal projection optical axis setting values by the optical axis posture adjustment unit based on the next detection result, correction amount, and information stored in the storage unit of the portable information terminal 301, and the projection An adjustment amount of the size adjustment unit and a correction amount of the projection trapezoidal distortion correction unit are calculated. Detection results of remote device attitude detection means and remote device position detection means, adjustment amount of irradiation size adjustment means, correction amount of irradiation trapezoid distortion adjustment means, detection results of projection attitude detection means and projection position detection means, and projection surface 11 position information.
That is, the projection setting calculation unit calculates the vertical adjustment amount Δθ and the horizontal adjustment amount Δψ by the optical axis posture adjustment unit of the projector 100, the adjustment amount of the projection size adjustment unit, and the correction amount of the projection trapezoidal distortion correction unit. .

  Then, a control signal for applying the calculation result of the projection setting calculation means to the projector 100 is transmitted by operating the operation button 314 of the display / operation unit 310 of the portable information terminal 301. In accordance with the received control signal, the projector 100 projects the projection light from the reference optical axis: Lp0 to the projection optical axis: Lpn adjusted by the adjustment amount Δθ in the vertical direction and the adjustment amount Δψ in the horizontal direction by the optical axis attitude adjustment unit. Adjust the axis posture. In addition, the size of the projection image 1 is changed by the adjustment amount of the projection size adjusting unit, and the projection trapezoidal distortion correcting unit corrects it to a rectangle. Then, the projected image 1 from the projector 100 is at the same position on the projection surface as the guide image 2 selected by the portable information terminal 301 as shown in FIGS. 12 (d), (e), and (f). The projection image 1 ′ is projected.

With the configuration described above, even when the portable information terminal 301 irradiates the guide image 2 from a position different from the projector 100, the projection optical axis of the projector 100 that projects onto the projection surface 11: Adjustment of the posture setting in the left-right direction can be easily performed. Therefore, it is possible to easily adjust the horizontal and vertical orientations of the projection optical axis: Lpn of the projector 100 that projects onto the projection surface 11, and the time required for the installation of the projector 100 by the operator can be shortened. Further, since the rectangular guide image 2 subjected to the trapezoidal correction can be irradiated onto the projection surface 11, it becomes easy to determine the projection layout.
Further, the other actions and effects described in the specific examples 1 and 2 described above can be obtained in the same manner.

Further, in this specific example, the projection setting calculation unit provided in the portable information terminal 301 is an adjustment amount Δθ in the vertical direction and an adjustment amount Δψ in the horizontal direction by the optical axis posture adjustment unit of the projector 100, and an adjustment amount of the projection size adjustment unit. And the correction amount of the projection trapezoidal distortion correcting means.
The calculation result is stored in the storage unit of the portable information terminal 301 or the image projection system management database, and installed at the installation position of the projector 100 when calculated by the projection setting calculation unit at a later date. The projection trapezoidal distortion correcting means may be corrected.
Further, it is possible to reduce the correction work such as trapezoidal distortion correction after the installation as compared with the case where the projector 100 is installed by irradiating the guide image 2 that is not rectangular, and the optimum projection image 1 can be easily and quickly applied to the projection surface 11. Can project.

  Further, at a later date, only the installation position and orientation of the projector 100 are detected again, and the projection setting calculation means adjusts each adjustment amount by the optical axis orientation adjustment means, adjustment amount by the projection size adjustment means, and correction amount by the projection trapezoid distortion correction means. Is recalculated. Then, based on the installation position and orientation of the projector 100, the adjustment of each adjusting unit and the correction of the projection trapezoidal distortion correcting unit may be performed.

  As described above, when the projector 100 is installed at a later date, it is not always necessary to irradiate the guide image 2 onto the projection surface 11 from the portable information terminal 301 again. Therefore, as in another example of the remote control device 300 shown in FIG. 6, the control for applying the calculation result of the projection setting calculation means to the projector 100 using only the portable information terminal 301 provided with the irradiation unit 330 separately. A signal may be transmitted. Also, the calculation result of the projection setting calculation means stored in the image projection system management database is acquired by the portable information terminal 301 in which another projection device remote software is installed, and the calculation result of the projection setting calculation means is stored in the projector 100. A control signal to be applied may be transmitted.

Further, the calculation result of the projection setting calculation means at the installation position of the projector 100 is used as a recommended projection layout candidate (history) of the projector 100, and the portable information terminal 301 including the irradiation unit 330 emits the guide image 2. Can also be used.
For example, as shown in FIG. 13A, when the guide image 2 is irradiated onto the projection surface 11, the frame 3 of the region of the largest rectangular projection image 1 that can be projected from a certain installation position of the projector 100 and the recommended The candidate of the projection image 1 to be displayed, that is, the frame 4 of the guide image 2 (history) selected in the past is displayed. At this time, the frame 3 is displayed in red and the frame 4 is displayed in green. In this way, by displaying the frame 3 of the region of the largest rectangular projection image 1 and the frame 4 that is a candidate of the recommended projection image 1, the selection of the guide image 2 to be applied to the projection image 1 can be quickly performed. It can also be done easily.

  Further, the frame 3 and the frame 4 can be distinguished not only by the color but also by the thickness of the frame line. Further, when the guide image 2 moves to an area that seems inappropriate for projecting the projection image 1, the frame 3 of the area of the projection image 1 having the largest rectangular shape is irradiated with a dotted line. It may be configured. By configuring in this way, it is possible to suppress the necessity of changing the projection layout after the projector 100 is once installed and then the participants of the main conference are seated. Further, as shown in FIG. 13B, the seating image 5 of the participant or the like when the projector 100 is installed and the layout layout (not shown) of the table 12 are superimposed on the guide image 2 and irradiated. It may be configured. By irradiating in this way, when determining the projection layout, it is easy to arrange the projector 100 assuming an actual venue layout.

When the frame 4 that is a candidate for the recommended projection image 1 is selected, the user can select the frame 4 displayed on the touch panel display 311 by touching the vicinity of the frame 4 with a finger or a pen. It can be constituted as follows.
Further, the irradiation of displaying the frame 3 and the frame 4 on the guide image 2 using the information of the calculation result of the projection setting calculation means stored in the image projection system management database or the like, and the frame 3 and the frame 4 described above are performed. Switching to the case of not displaying can be performed as follows, for example. An operation button for selecting whether or not to use the recommended projection layout is displayed on the touch panel display 311 and can be configured to be switched by pressing either the displayed operation button or the operation button 314. .

Next, an example of a control flow of the image projection system 700 using the information stored in the image projection system management database used in the specific example 4 and the projection layout candidate (history) of the projector 100 will be described with reference to the drawings. explain. That is, the control flow of the operation method of the image projection system 700 will be described with reference to the drawings.
14 is a flowchart showing an example of the processing flow of the image projection system management database, FIG. 15 is a flowchart showing an example of the processing flow of the portable information terminal 301, and FIG. It is an example at the time of displaying a recommended projection layout on a touch panel display. FIG. 17 is a flowchart illustrating an example of a processing flow of the projector 100. In the following description, the image projection system management database to which the portable information terminal 301 and the projector 100 are to exchange data will be described as the database server 510 to which data signals are transmitted and received unless otherwise required. .

(Database server flow)
As shown in FIG. 14, when new conference information is registered in the conference room reservation database of the groupware database, the database server 510 searches (collects) the following conference holding information and projection condition information. (S101).
The meeting holding information includes a meeting ID, a start time, an end time, a participant, a reservation person, an operator, and the projector 100 of the corresponding meeting from a plurality of data tables such as a meeting room reservation database and an employee list database. Search for information on equipment used in meetings.
As the projection condition information, information such as conference room reference position information, non-projection plane information, and information on the projector 100 to be used is obtained from a plurality of data tables such as a conference room database, a conference room projection condition database, and a projector management database. Search for.

  Also, in this step, text information and image information that allows the reservation person and operator to check the equipment and size of the conference room, the layout of the table and seats, etc. are collected as projection condition information from the conference room database and conference room projection condition database. To do. Also, history information of past projection layouts using the projector 100 is also searched at the venue 10. By collecting text information and image information as projection condition information as described above, a reservation person or an operator can use the projection device remote software from each portable information terminal 301 to store the information on the touch panel display 311. It can be displayed quickly and convenience can be improved. Even a general participant who is not a conference organizer, such as a reservation person or an operator, can refer to the conference room reservation database itself as long as the participant has the authority to refer to the conference room reservation database.

If the retrieved meeting holding information includes information that matches the projector 100 managed by the image projection system management database, the process proceeds to the next step while retaining the retrieved information (Yes in S102). If there is matching information in this step (Yes in S102), an email indicating that the management of the image projection using the projector 100 has been started in the image projection system management database is sent to the portable information terminal 301 of the operator. Alternatively, it may be configured to send to. Further, the message may be displayed on the touch panel display 311 of the operator's portable information terminal 301 instead of the mail. In the following description, the mail and the display of the message are simply referred to as “message notification”. Call it.
On the other hand, if there is no information that matches the projector 100 managed in the image projection system management database in the retrieved conference holding information, the search is stopped until the equipment information in the conference room reservation database is newly registered or updated. (No in S102). That is, until the equipment information in the conference room reservation database is newly registered or updated, the image projection management using the projector 100 is stopped in the image projection system management database, and the searched information is also temporarily deleted. To do.

If there is information that matches the projector 100 in the retrieved conference holding information (Yes in S102), it can be detected that the operator has entered any conference room managed after the conference start time (preparation start time). If so, the following confirmation is performed (S103).
Specifically, there are two stages of confirmation when entering a room.
The first confirmation stage is confirmation of whether the correct (registered) operator is using the portable information terminal 301 managed by the operator, that is, the operator and the portable information terminal 301. . As for the confirmation method, since the portable information terminal 301 displays the operation screen of the projector remote software or the confirmation / input screen of the conference room reservation database, the operator cannot display it without entering his user ID and password. It is configured as follows. The portable information terminal 301 is registered with a terminal ID when using the projection apparatus remote software, and the information registered in the image projection system management database and the portable information terminal 301 used by the operator and the operator. Confirmation can be done by collating with the information.

The second confirmation stage (entrance detection) is confirmation of whether or not the confirmed operator and the portable information terminal 301 of the operator have entered the venue 10 which is a correct conference room. The confirmation method at the venue 10 includes the conference room ID stored in the IC tag 531 attached to the wall surface of the venue 10 and the conference of the venue 10 acquired from the database server 510 by the portable information terminal 301 of the reservation person or operator. This can be done by checking the room ID.
In a configuration in which the IC tag 531 is not used, confirmation can be performed by holding the portable information terminal 301 over a stationary projector or an IC card that also serves as a card key of a conference room that is received at the reception. In addition, in a venue where the detection accuracy of the remote device position detection means such as GPS is high, the position information detected by the remote device position detection means and the position information of the venue 10 can be verified.

If they match, the projector 100 can be operated from the portable information terminal 301 of the operator, and the usage status of the conference room reservation database is changed from reserved to in use, and the next step is performed. Proceed (Yes in S104).
Specifically, if both match, a signal permitting remote operation of the projector 100 by the portable information terminal 301 is transmitted from the database server 510 to the portable information terminal 301, and the use status of the conference room reservation database Change during use. When communication from the venue 10 to the database server 510 cannot be performed directly, remote operation of the projector 100 can be permitted by the projector remote software itself based on confirmation with the IC tag 531 or the IC card. However, the change of the usage status of the conference room reservation database to in-use can be communicated after being received from another personal computer or the like at the reception or after the remote operation of the projector 100 by the projector remote software is permitted. Need to go to the area and change

  On the other hand, if they do not match (incorrect), this confirmation is repeated until the reservation person or operator enters the venue 10 which is the correct meeting room or the meeting end time is reached (No in S104). . In addition, when the conference room that has entered is wrong, a message may be notified to the reservation person or the operator. By providing this step, it is possible to prevent the reservation person or operator from starting preparations for image projection in the wrong meeting room, and the meeting can be held smoothly.

When it is confirmed that the confirmed operator and the portable information terminal 301 of the operator have entered the venue 10 which is a correct conference room (Yes in S104), the operator's portable information terminal 301 or the projector 100 The process shifts to a waiting state for an information acquisition signal (S104). In this step, when the information acquisition signal is received from the portable information terminal 301 or the projector 100, the conference holding information and the projection condition information searched in the first step (S101) are sequentially transmitted according to the received information acquisition signal. (S105).
In addition, when communication with the database server 510 cannot be performed directly from the venue 10, all the meeting holding information and projection condition information retrieved in the first step (S101) are acquired in the portable information terminal 301 in an environment where communication is possible. Can also be stored. However, since the amount of data may increase, a part of the projection condition information of the venue 10 is stored in the IC tag 531 or the IC card, and only the conference holding information is acquired and stored in the portable information terminal 301. You can also.

After that, when the information of the portable information terminal 301 related to the determined irradiation layout and the setting values and correction values of various projection settings of the projector 100 related to the projection layout are received from the operator's portable information terminal 301 (S106, S107) Yes), go to the next step.
On the other hand, until it is received (No in S106 and S107), the state where the conference holding information and the projection condition information searched in the first step (S101) are sequentially transmitted according to the received information acquisition signal is maintained (S105). ).

When received (Yes in S106 and S107), the information of the portable information terminal 301 related to the determined irradiation layout, and the setting values and correction values of various projection settings of the projector 100 related to the projection layout are used as the projection layout of the conference. Information is stored (S108). Note that unless the projection layout is changed and information related to the change is received from the operator's portable information terminal 301, the stored irradiation layout and information related to the projection layout are maintained in the projected state until the end of the conference.
Also, after storing as projection layout information of the main conference, projection request confirmation information consisting of the projection layout information is generated and transmitted to the person in charge of the main conference (requester), the chairperson, etc. (S109).

(Flow of portable information terminal)
As shown in FIG. 15, the portable information terminal 301 can acquire the conference holding information and the projection condition information of the conference from the database server 510 after the conference using the projector 100 is registered in the conference room reservation database. Become. Specifically, the information acquisition signal for acquiring the information regarding the conference holding information and the projection condition information regarding the conference is transmitted to the database server 510 and acquired in advance or after entering the meeting place 10 where the conference is held. (S201). At this time, as described in the flow of the database server, whether or not the correct (registered) operator uses the portable information terminal 301 managed by the operator, that is, the operator and the portable information terminal 301. Confirm also.

  Then, it is confirmed whether the conference searched (registered) in the database server 510 matches the conference in which the projector 100 is remotely operated from the operator's portable information terminal 301 at the venue 10 (S202). If there is no matching information in this confirmation (No in S202), a message indicating that the conference corresponding to the conference room reservation database or the information using the projector 100 is not registered in the database server 510 is displayed on the touch panel display 311. And exit. On the other hand, if there is matching information (Yes in S202), the process proceeds to the next step.

When there is matching information (Yes in S202), when entering the venue, it is confirmed whether or not the venue that has entered the venue is the venue 10 where the main conference is held. Whether or not it is the venue 10 is confirmed by the conference room ID stored in the IC tag 531 attached to the wall of the venue and the venue 10 acquired from the database server 510 by the portable information terminal 301 of the reservation person or the operator. This can be done by checking the conference room ID. Further, as described above, confirmation may be made by remote device position detection means such as GPS.
Also, it is confirmed whether the projector at the venue or brought in matches the projector 100 provided as the conference holding information. That is, it is confirmed whether or not the projector in the venue or brought in is used. Specifically, once the main power of the projector is turned on, it is confirmed whether it matches the information acquired in the portable information terminal 301, or communication is performed between the portable information terminal 301 and the IC tag attached to the projector. Check.

  As described above, by confirming whether or not the venue that has entered is the correct venue 10 and whether or not the projector at the venue or the projector brought in is the projector 100 that is scheduled to be used, Time loss for preparation using a projector can be reduced. If either or both of the venue and the projector are incorrect, the fact is displayed on the touch panel display 311 and notified to the operator (No in S203 and S204). As described above, when either or both of the venue and the projector are wrong, the user enters the correct venue 10 again or switches to the correct projector 100. Then, it is confirmed again whether or not the venue that has entered is the correct venue 10 and whether or not the projector at the venue or the projector brought in is the projector 100 to be used (S203).

If it is confirmed that the venue that has entered is the correct venue 10 and that the projector at the venue or the projector brought in is the projector 100 to be used (Yes in S203 and S204), the process proceeds to the next step.
Within the hall 10, detection of the position and orientation information of the portable information terminal 301 is started, and the detection result is sequentially updated and stored. Also, the projector 100 is once arranged at a rough position, the main power supply is turned on, and detection of the position and orientation is started (S205).
Next, the projection surface 11 in the venue 10 is selected with the irradiation unit 330 of the portable information terminal 301 facing the projection surface 11 on which the image is projected. Then, as shown in FIG. 16, the projection layout (history) recommended by the projector 100 acquired from the database server 510 is displayed on the touch panel display 311, and the operator determines whether or not to select the displayed projection layout ( S206).

  Here, as a recommended projection layout, as shown in FIG. 16, the projection surface 11 and the projector 100 are illustrated and displayed on a plan view illustrating the interior walls, doors, windows, and the like of the venue 10. As for the projection surface 11, the position in the width direction is displayed at a distance [m] from one or both of the venues 10, and the height from the floor surface to the projection image: h 1 [m], The height h2 [m] and the height from the projected image to the ceiling: h3 [m] are displayed numerically. For the projector 100, the arrangement position in the X direction (width direction) and the arrangement position in the Y direction (depth direction) (distance from the projection surface 11) are the distance [m] from one or both of the venues 10. Displayed at a distance [m] from one or both of the venues 10. Then, an angle [deg] between the perpendicular to the projection surface 11 and the projection optical axis is displayed as the posture with respect to the projection surface 11 and the height of the base point of the optical axis of the projector 100 from the floor surface: h0 [ m] and the angle formed by the horizontal of the optical axis: θ [deg] are displayed. Alternatively, the portable information terminal 301 may be arranged at the position of the projector 100 displayed, and the projection image 11 may be irradiated to the projection surface 11 so that a more specific projection layout can be confirmed.

Here, when the recommended projection layout is selected (Yes in S207), the information on the portable information terminal 301 related to the selected projection layout or the irradiation layout when the selected guide image 2 is irradiated, the position of the projector, and The attitude detection result is stored (S210).
On the other hand, when the recommended projection layout is not selected (No in S207), the operator moves the guide image 2 irradiated on the projection surface 11 and changes the size of the guide image 2 to be applied to the projection image 1. 2 is selected (S208). Here, this selection operation is repeated until the guide image 2 to be applied to the projection image 1 can be selected (Yes in S209) (No in S209). And if it can select (Yes of S209), the information of portable information terminal 301 concerning the irradiation layout at the time of irradiating the selected guide image 2 and the detection result of the position and posture of the projector will be stored (S210).

Next, based on the information stored in the portable information terminal 301 related to the stored irradiation layout and the detection result of the position and orientation of the projector, the projection setting calculation unit calculates setting values and correction values for various projection settings related to the projection layout. . Further, the calculated projection setting calculation means stores setting values and correction values for various projection settings related to the projection layout (S211).
Then, the calculated projection setting calculation means transmits a control signal based on the setting values and correction values of various projection settings related to the projection layout to the projector 100 (S211). This transmission is repeated until the reception signal from the projector 100 cannot be received (No in S213), that is, until transmission is possible. On the other hand, if the transmission is confirmed (Yes in S213), information on whether or not adjustments of the setting values and correction values of various projection settings can be received from the projector 100 based on the transmitted control signal. It waits until it does (S214).

  When information indicating that the setting values and correction values of various projection settings cannot be adjusted is received from the projector 100 (No in S215), the following processing is performed. Difference information between the selected projection layout and the position and orientation of the projector 100 based on the information related to the selected irradiation layout, the detection result of the position and orientation of the projector 100, the information on the projection setting items that cannot be adjusted, and the information on the preparation range Is calculated by the difference information calculation means. Based on the calculated difference information, the amount of movement for moving the projector 100 to the changeable range of setting values and correction values of various projection settings is displayed on the projection layout diagram shown in FIG. Then, after moving and arranging the projector 100, the detection of the position and orientation information of the portable information terminal 301 is started again, and the projector 100 also turns on the main power supply and starts detecting the position and orientation. Return to (S205).

  On the other hand, if information indicating that adjustment is possible is received (Yes in S215), the information related to the stored irradiation layout, the setting values and correction values of various projection settings related to the projection layout, and the conference holding information of the plenary session Association is performed (S216). Although details will be described later, if the projector 100 can determine that the setting values and correction values of various projection settings can be adjusted by various projection setting adjustment units, the projector 100 can adjust the portable information terminal 301. Send information and make adjustments.

Then, the information of the portable information terminal 301 related to the stored (determined) irradiation layout and the setting values and correction values of various projection settings of the projector 100 related to the projection layout are transmitted to the database server 510 (S217). During this transmission, if a response signal indicating that it has been received from the database server 510 cannot be received (No in S218), transmission to the database server 510 is performed until a response signal indicating that it has been received from the database server 510 (Yes in S218). repeat.
However, if the venue 10 is in an environment where communication with the database server 510 is not possible directly, an option to be transmitted when moving to an environment where communication is possible is displayed, and if this is selected, the process proceeds to the next step.
In addition, when transmitting to the database server 510, the setting values and correction values of various projection settings of the projector 100 related to the projection layout, and information on the position and orientation are transmitted to a personal computer that is a signal generator connected to the projector 100. You may comprise so that it may transmit. In this way, by transmitting to a personal computer or the like, it becomes possible to notify the presenter who operates the personal computer in advance of the projection layout.

If the transmission of the above information to the database server 510 is completed or it is selected to be transmitted when moving to an environment where communication is possible, the setting values of various projection settings until the main conference ends or the projection layout needs to be changed. And the correction value is maintained (S219).
If it is necessary to change the projection layout (Yes in S220), the detection of the position and orientation information of the portable information terminal 301 is started again, and the projector 100 also turns on the main power and changes the position and orientation. The process returns to the step of starting detection (S205). On the other hand, when it is not necessary to change the projection layout (No in S220), it is determined whether or not the main conference has ended (no conference extension). If the conference has not ended (No in S221). ), Setting values and correction values of various projection settings are maintained (S219).
When the main conference ends (Yes in S221), the information of the portable information terminal 301 related to the stored (decided) irradiation layout and the setting values and correction values of various projection settings of the projector 100 related to the projection layout are deleted. . However, if the transmission of the information to the database server 510 is not completed, the information is deleted after the transmission is completed.

(Projector flow)
As shown in FIG. 17, in the projector 100, after the conference using the projector 100 is registered in the conference room reservation database, the conference holding information and the projection condition information of the conference can be acquired from the database server 510. Specifically, the information acquisition signal for acquiring the information regarding the conference holding information and the projection condition information regarding the conference is transmitted to the database server 510 and acquired in advance or after entering the meeting place 10 where the conference is held. (S301).
At this time, if the main power supply of the projector 100 is turned on, information is acquired from the database server 510 via a wireless LAN or a wired LAN. On the other hand, when the venue 10 cannot communicate directly with the database server 510 or when the main power of the projector 100 is turned off, the portable information terminal 301 or the like is attached to the IC tag provided in the projector 100. The information is acquired once through.

Next, the acquired reception information is stored, and the operation status is transmitted to the database server 510 and the portable information terminal 301 (S302). At this time, when the acquired reception information is stored, or when the response signal indicating that the received information is received from the database server 510 and the portable information terminal 301 cannot be received (No in S303), the reception information is stored and transmitted again. It repeats until transmission is successful (Yes in S303).
If the storage and transmission of the received information are successful (Yes in S303), the projector 100 detects the position and orientation (S304). At this time, when the position and orientation cannot be detected (No in S305), the detection of the position and orientation is repeated again until the detection of the position and orientation is successful (Yes in S305).

If the position and orientation of the projector 100 can be detected (Yes in S305), the detection result is transmitted to the portable information terminal 301 (S306). At this time, when the portable information terminal 301 cannot receive a response signal indicating that the detection result has been received (No in S307), until the position and orientation of the projector 100 succeeds in transmitting the detection result (Yes in S307). )repeat.
Thereafter, a control signal based on setting values and correction values of various projection settings related to the projection layout is received from the portable information terminal 301 of the operator. Then, based on the received control signal, it is determined whether or not the various projection setting adjusting means can be adjusted to the set values and correction values of various projection settings (S308).

If it is determined in the above determination that adjustment cannot be performed (No in S309), information indicating that adjustment is not possible and projection setting items that cannot be adjusted (exceeding the adjustment range) are displayed on the portable information terminal 301 of the operator. Transmit (S310). Then, the projector 100 is re-installed based on the target projection layout calculated by the difference information calculation unit of the portable information terminal 301, the position and orientation of the projector 100, and the difference information. After that, the process starts again from detection of the position and orientation of the projector 100 (S304).
On the other hand, if it is determined that adjustment is possible (Yes in S309), information indicating that adjustment is possible is transmitted to the portable information terminal 301 of the operator, and various projection setting adjustments are performed based on the received control signal. To adjust the setting values and correction values of various projection settings (S311).

  Thereafter, the input line and the input image of a personal computer or the like that is a signal generator connected to the projector 100 are discriminated, and when the projection lamp is turned on, projection of the input image is started (S312). Then, the sensor unit 161 detects whether or not the projection image 1 based on the input signal can be normally projected on the projection surface 11. If it is determined that the projection is not successful (No in S313), the input line and the input image are re-determined, and the input image is projected again. If the projection is successful, the process proceeds to the next step (S313). Yes).

If the projection image 1 can be normally projected on the projection surface 11 (Yes in S313), the setting values and correction values of various projection settings are maintained until a new control signal is received from the portable information terminal 301 of the operator. To do. That is, the projection state is maintained until the end of the conference unless a change related to the projection layout occurs.
If the input line and the input image are re-determined many times and if the input image cannot be projected normally even after the input image is projected, there is a possibility that a malfunction that cannot be detected has occurred in the projector 100. , Send a message to the operator's portable information terminal.

As described above, by performing each process in the image projection system 700, the projection layout can be quickly and easily determined by the projector 100.
Further, information relating to the projection layout when the image projection has been performed in the past can be stored as a recommended projection layout candidate in the image projection system management database constructed in the database server 510 and reused. Therefore, in addition to shortening the time required for the initial installation of the projector 100 in the venue 10, it is also possible to select from the recommended projection layout when it becomes necessary to change the projection layout after the main meeting is held. By doing so, the time required for the change can be shortened.
In addition, most of the basic installation work can be performed according to the above-described processing flow, and even when the projector 100 is used for the first time, the time for installing the projector 100 can be shortened. .

  Further, since the portable information terminal 301 is used as the remote operation device 300, when the recommended projection layout shown in FIG. 16 is displayed on the touch panel display 311, the table 12 in the hall 10 or the seating positions of the participants Etc. can also be plotted and displayed. Information such as the table 12 and the seating positions of the participants can be displayed based on information collected from a conference room database table or the like on the database server 510 as projection condition information. In this way, it becomes easier to imagine the layout in the venue such as the seating positions of the participants when actually projecting an image, and the projection layout can be determined quickly and easily.

In addition, since information such as the conference room reservation database on the database server 510 can be used, troubles such as installation of the projector 100 or installation of the wrong projector in the wrong conference room or date / time are possible. Occurrence can also be suppressed.
In addition, if the use of the venue 10 is not reserved before the meeting time of the venue 10 to be used, the installation work of the projector 100 can be permitted early for a predetermined time (about 10 minutes), The convenience for the operator can be enhanced. Alternatively, the projector 100 may be allowed to be installed after the previous meeting is completed. Conversely, when the main conference is extended, the usage status of the conference room reservation database is changed from being used to during the conference extension, or the usage is extended to the next venue 10 or the user of the projector 100. It is also possible to send a message to that effect. As described above, not only the installation of the projector 100 related to an individual meeting but also the convenience of a plurality of users using the image projection system 700 can be improved.

  In the present embodiment, the example in which the projection setting calculation unit is provided in the portable information terminal 301 and the control signal based on the calculation result is transmitted to the projector 100 has been described. However, the present invention is not limited to such a configuration, and the projection setting calculation unit may be provided on the projector 100 or the database server 510. In addition, the information transmitted from the portable information terminal 301 to the projection setting calculation unit may be only information related to the selected irradiation layout, and the projector 100 may perform conversion to the control signal.

  Further, in the present embodiment, the case where the rectangular projection image 1 that is normally performed is projected onto the projection surface 11 has been described, but the present invention is not limited to such a configuration. For example, the present invention can be applied to a case where the projection image 1 intentionally causing trapezoidal distortion is projected onto the projection surface 11 or the rectangular projection image 1 is projected onto the projection surface 11 while being rotated. When applied to such image projection, the rotation about the X axis in the dynamic coordinate system of the portable information terminal 301 or the projector 100 described above, that is, the rotation angle about the Xs axis is also calculated for each roll angle: φ. It can be realized by using it as a variable (parameter) in the means.

(Example 2)
Example 2 of this embodiment will be described with reference to the drawings.
In the first embodiment, the configuration for quickly and easily determining the projection layout of the projector 100 has been described. However, in the image projection system 700 according to the present embodiment, the configuration relating to the adjustment method of various projection setting adjustment units excluding the projection layout. Will be described. Note that the same configuration and processing as those of the first embodiment described above will be omitted as appropriate.

  FIG. 18 is a diagram illustrating a case where uneven illuminance or uneven color occurs in the projected image 1 due to the venue layout of the venue 10 where the image is projected and the projection layout of the projector 100 and the material of the projection surface 11 according to the present embodiment. FIG. 18A is an explanatory diagram when the layout of the hall 10 causes the case, and FIG. 18B is an explanatory diagram when the projection layout of the projector 100 causes the case. FIG. 19 is an explanatory diagram of an example in which illuminance unevenness or color unevenness generated in the projected image 1 due to the material of the projection surface 11 or the like occurs in the confirmation pattern. 19A shows no illuminance unevenness or color unevenness. FIG. 19B shows an illuminance unevenness or color unevenness. FIG. 19C corrects and suppresses illuminance unevenness or color unevenness. It is explanatory drawing in the case of doing. FIG. 20 is an explanatory diagram when a confirmation pattern is projected onto a material whose projection surface 11 is difficult to maintain flatness, such as a curtain.

  FIG. 21 is an explanatory diagram when the image configuration of the projected image to be projected changes. FIG. 21A is an image configuration mainly including text, FIG. 21B is an image configuration mainly including a pattern, and FIG. ) Is an example of an image configuration in which text and pictures are mixed. FIG. 22 is a flowchart showing an example of the processing flow of the portable information terminal 301 when the confirmation pattern is different for each image configuration. FIG. 23 is a projector when the confirmation pattern is different for each image configuration. It is a flowchart which shows the example of a flow of 100 processes.

  A conventional projector that automatically adjusts each projection setting has only a few types of confirmation patterns that can be used for automatic adjustment under standard conditions for each projection setting. Specifically, it corresponds to the main image quality, luminous intensity, and projection layout of the projector, and there are many cases where adjustment cannot be performed in actual image projection performed in various environments and projection conditions. For this reason, depending on the environment of the venue where the image is projected, the material of the projection surface 11, and the projection layout, there are many cases where a suitable projection setting cannot be automatically performed. Examples of the environment of the venue for image projection include the presence / absence of an opening through which external light is inserted depending on the time of day, the brightness of the indoor lighting provided on the ceiling or the like when performing image projection, the lighting layout, and the like. In addition, even when a plurality of confirmation patterns are easily set for the same projection setting, the operator is often confused as to which confirmation pattern should be used.

  Therefore, in the image projection system 700 of the present embodiment, the following information is also stored as projection condition information in the image projection system management database operated on the database server 510, and an optimum confirmation pattern is used by using it together with the projection layout. Made available. The layout of the venue 10 for image projection, such as the opening position and lighting, the characteristics of the projection surface 11 (material, specifications, length and width, suitable projection angle, reflection angle, etc.), the projection layout of the projector 100, These are confirmation pattern candidates, characteristic image configuration information of the projected image 1, and the like. Further, the image projection system management database operated on the database server 510 also functions as a pattern providing unit that provides a confirmation pattern.

  First, an example of illuminance unevenness and color unevenness caused by the venue layout of the venue 10 and the characteristics of the projection surface 11 will be described. In FIG. 18A, an image is projected in an environment where the interior of the venue 10 is bright using a curtain 15 provided with a plurality of windows 14 on a side wall surface perpendicular to the projection surface 11 and transmitting normal light instead of a light shielding curtain. The case of performing will be described. In such an environment, even if the projection optical axis of the projector 100 is perpendicular to the projection surface 11, the image on the projection surface 11 is as in the case where the light shielding curtain shown in FIG. All the areas (1), (2), and (3) from the left side in the figure are not uniform. The external light transmitted through the curtain 15 in FIG. 18A is inserted into the left side of the projection image 1 on the projection surface 11 in the drawing along with the color of the curtain 15. As a result, illuminance unevenness and color unevenness occur in the order of the areas (1), (2), and (3) from the left side in the figure.

  Even when a dedicated screen is used, it is difficult to completely suppress illuminance unevenness and color unevenness with respect to light inserted from the side. In addition, depending on the characteristics of the screen, the illuminance unevenness and the color unevenness may occur.Therefore, when the same confirmation pattern is used in all areas, all the values are detected based on the values detected by the pattern detecting means. It is difficult to suitably correct this area. Therefore, in this embodiment, in order to suppress the illuminance unevenness and the color unevenness, as shown in FIG. 19C, the illuminance and the confirmation pattern in the left area (1) and the central area (2) in the figure are displayed. The confirmation pattern that suppresses uneven color was projected.

  Specifically, the portable information terminal 301 obtains the time zone when the image is projected at the venue 10 from the database server 510, the weather, the transmitted color of the curtain 15, the characteristics of the projection surface 11, and the confirmation pattern candidate. To do. Then, from the acquired information and information such as the projection layout of the projector 100, a plurality of confirmation pattern candidates stored in the database server 510 as confirmation patterns to be used in the areas (1), (2), and (3). Select (discriminate) from

  The portable information terminal 301 transmits the acquired confirmation pattern to the projector 100, and the projector 100 projects the received confirmation pattern onto the projection surface 11 from the projection mechanism unit 130 that also functions as a pattern projection unit. And it detects with the sensor part 161 which is a pattern detection means. Based on the confirmation pattern information of each region and the detection result of each region detected by the pattern detection unit of each projector 100, the projection setting calculation unit included in the projector 100 performs the illuminance setting and the tone setting projection setting for each region. An adjustment value of the adjusting means is calculated. Thereafter, the illuminance setting and the color tone setting are controlled based on the calculation result. Specifically, by controlling the inclination of the light reflecting surface of each macro mirror of the projection image creating unit 131 by time-division gradation expression, uneven illuminance or color when the projected image 1 is projected on the projection surface 11 It is possible to approach the state shown in FIG. 19A, which is uniform over the entire surface where unevenness is suppressed.

  In addition, as described above, when the projector 100 performs oblique projection as shown in FIG. 18B instead of the conditions such as the venue layout and the illumination when performing image projection, the same as the venue layout described above. Irradiance unevenness and color unevenness caused by the above may occur. This is mainly caused by the angle of light projected from the projector 100 and the characteristics of the projection surface 11 (particularly, the characteristics of the reflection angle with respect to the incident angle). Even in such a case, the confirmation pattern used in the areas (1), (2), and (3) is determined based on the characteristics of the projection surface 11 on which the image is projected at the venue 10 and information such as the projection layout of the projector 100. And selecting (determining) a plurality of confirmation pattern candidates stored in the database server 510.

  As described above, in this embodiment, the above-described projection condition information and the confirmation pattern stored in the image projection system management database are obtained from the image projection system management database operated on the database server 510 by the portable information terminal 301. get. Then, the acquired confirmation pattern information is transmitted to the projector 100, and the projector 100 calculates setting values or correction values of various projection settings using the confirmation pattern, and performs adjustment by various projection setting adjustment means. Thereafter, the confirmation pattern used in the projector 100 and the adjustment amount or correction amount calculated using the confirmation pattern are transmitted to the portable information terminal 301. Finally, it is stored as history information in a predetermined data table of the image projection system management database operated on the database server 510. This stored information can also be used as a confirmation pattern candidate to be used preferentially when there is matching projection condition information in subsequent image projection using the projector 100.

  As described above, in this embodiment, the portable information terminal 301 acquires the projection condition information or the confirmation pattern from the database server 510 and the projector 100 uses the confirmation pattern. The configuration is not limited. For example, when the projector 100 is configured to acquire projection condition information or confirmation pattern information and cannot communicate directly with the database server 510, the above information is obtained from the IC tag 531 or the like via the portable information terminal 301. It can also be configured to obtain. Further, the confirmation pattern and the adjustment amount or the correction amount calculated using the confirmation pattern can be transmitted to the database server 510 via the portable information terminal 301.

Further, as a communication means between the portable information terminal 301 and the projector 100, not only communication using a wireless LAN or the like but also peer-to-peer using a near field communication standard (NFC) using an IC tag. Communication is also possible.
In the above-described two examples, the example in which the confirmation patterns are different in the three regions has been described. However, the present invention is not limited to such a configuration. For example, the confirmation pattern is divided not only in the horizontal direction but also in the vertical direction. In addition, the image may be divided into more regions.
In the above-described two examples, an example in which a plurality of square dot patterns are used as confirmation patterns has been described, but the present invention is not limited to such a configuration. In particular, an appropriate confirmation pattern such as a dot shape (large / small, circular / rectangular), color (transparent color, yellow), density (high / rare), density, and the like is generated in accordance with the characteristics of the projection surface 11. be able to.

  Next, the case where the projection surface 11 is composed of a screen or the like that cannot maintain flatness will be described. First, the background in which it is necessary to use the projection surface 11 that cannot maintain flatness will be described. Today, conferences using projectors are not limited to conference rooms with fixed projectors, but can be held anytime, anywhere in various locations, conference rooms, and spaces such as rental rooms and hotel conference rooms. . Especially for companies that do not have many meeting rooms, or when sharing projectors, it is important to use portable projectors and mini projectors that can be easily carried around. Depends on the environment and the projection surface. Depending on the location where the conference or the like is held, there may be a case where a screen or the like that cannot maintain flatness, that is, cannot be firmly fixed, must be used as the projection surface.

  As shown in FIG. 20, when the region of the projection surface 11 ′ onto which the projection image 1 ′ is projected is composed of a screen or the like, even if the confirmation pattern is projected, it is undulated by the air-conditioning airflow, and the confirmation pattern In some cases, it was difficult to adjust various projection settings. This is because, as described above, there are few types of confirmation patterns provided in the conventional projector, and there is no confirmation pattern corresponding to the projection surface 11 ′ that is wavy.

  In the configuration of this embodiment, as described above, the projection condition information and the confirmation pattern related to the venue 10 that performs image projection can be acquired from the database server 510. Therefore, for example, information on the projection surface 11 ′ (screen) waved in the projection condition information and a confirmation pattern made up of a dot pattern or the like suitable for the waved projection surface 11 ′ generated in advance are projected at high density. Then, it is divided into a plurality of regions having different curvatures of wavy peaks and valleys. Then, for each of the divided areas, it is possible to calculate the adjustment values of the setting values and correction values of various projection settings based on the detected detection result and the information of the projected confirmation pattern.

As described above, even if the projection surface 11 ′ cannot maintain flatness, various projection settings using the confirmation pattern can be automatically set, thereby improving the convenience for the operator and improving the projector 100. The range of use can be expanded.
In addition, the above projection condition is obtained by formulating the number of relations between the information about whether the venue 10 is indoor or outdoor, information on the air-conditioning ejection direction and air volume, and the vertical wavy shape of the projection surface 11 ′. By storing the information, it is possible to adjust the projection setting with higher accuracy.

  Next, in the case where the image configuration of the projected image 1 projected on the projection surface 11 by the projector 100 changes from text main body, picture main body, text and picture mixed, in addition to settings such as illuminance and color tone, The sharpness and contrast ratio need to be set appropriately. For example, although it depends on the lighting etc. in the venue 10, in the image configuration mainly composed of the text (A) shown in FIG. 21A, settings such as increasing sharpness, modest illuminance, and increasing contrast are common. Easy to see. Further, in the image configuration mainly composed of the pattern (B) shown in FIG. 21B, settings such as a slightly higher illuminance and saturation, a slightly lower sharpness, and a medium contrast are generally easy to see.

However, as shown in FIG. 21C, in the case of an image configuration in which text (A) and picture (B) are mixed, it is difficult to cope with the confirmation pattern provided in the conventional projector.
Therefore, in this embodiment, the image signal of the projection image is read in advance from a signal generator such as a personal computer, and the characteristic image configuration is extracted and stored, and the duration of the image configuration is also stored. . The portable information terminal 301 is suitable for each extracted image configuration. That is, in FIG. 21C, the text (A) area is suitable for text, and the picture (B) area is suitable for picture. Select a pattern and project. Then, various projection settings are calculated by the projection setting calculation means from the information of the confirmation pattern for each region and the detection result detected by the pattern detection means, and the setting values or correction values of the various projection setting adjustment means are adjusted. Also, the timing at which the confirmation pattern is interrupted into the image signal is calculated from the duration of each image configuration, and the confirmation pattern is projected at the calculated timing and detected by the pattern detection means.

  Next, adjustment of various projection settings using a confirmation pattern when a characteristic image configuration is acquired will be described in more detail with reference to the flowcharts of FIGS. In the following description, it is assumed that the information related to the projection layout described in the first embodiment is acquired and stored in the portable information terminal 301, the projector 100, and the database server 510. First, the processing flow of the portable information terminal 301 will be described.

(Flow of portable information terminal)
As shown in FIG. 22, the portable information terminal 301 searches (collects) information on the projection surface 11 (screen) and confirmation pattern candidates as projection condition information based on information such as the determined projection layout of the projector 100. (S401). Specifically, the information acquisition signal is transmitted to the database server 510 to acquire the material, specifications, portrait and landscape, and confirmation pattern candidates of the projection surface 11 and store them in the storage unit of the portable information terminal 301.
If the information on the projection surface 11 cannot be acquired (No in S402), the information acquisition signal is transmitted to the database server 510 again, and the material, specifications, portrait and landscape of the projection surface 11, and confirmation pattern candidates. Repeat until you get and memorize.

  If the above information is acquired (Yes in S402), a personal computer or the like used for projecting an image is connected to the portable information terminal 301, and the image information (image signal) of the projected image is read. A typical image configuration is automatically acquired and stored in the storage means (S403). Alternatively, the operator may select and acquire a characteristic image configuration visually and store it in the storage unit. Also, the duration of each image configuration is acquired and stored at the same time. If the image configuration cannot be acquired (No in S404), the process is repeated until it can be acquired. At this time, the projector remote software also functions as an image configuration detection unit that automatically acquires a characteristic image configuration and a duration detection unit that detects the duration of the characteristic image configuration.

If a characteristic image configuration can be acquired (Yes in S404), a confirmation pattern to be used for each image configuration is determined from the confirmation pattern candidates acquired from the database server 510 (S405). Here, the confirmation pattern is discriminated based on the conference room environment, projection surface information, projection layout, and information on each image configuration stored in the storage unit of the portable information terminal 301.
Based on the determined duration of each image configuration and the information of each image configuration, the interrupt timing for each image configuration of the confirmation pattern generated or determined is calculated by the projector remote software (S406). That is, at this time, the projector remote software also functions as a timing calculation unit.

  Thereafter, the confirmation pattern used for each image configuration and its interrupt timing are stored in the storage means (S407). Then, the confirmation pattern to be used for each stored image configuration and its interrupt timing are transmitted to the projector 100 (S408). If a response signal to the information transmitted from the projector 100 cannot be received (No in S409), that is, if transmission is not possible, transmission is repeated at predetermined intervals until transmission is possible.

If a response signal to the information transmitted from the projector 100 is received, that is, if transmission is possible (Yes in S409), the process proceeds to confirmation of the projection time of the projection image (S410), and the projection image continues (S411). No) and the confirmation of the projection time is repeated until the end.
When the projection image is completed (Yes in S411), the projection image pattern detection result and the correction result using the confirmation pattern for each image configuration are received from the projector 100 (S412). The pattern detection result and correction result of the received projection image are also stored in the storage means (S413). Then, the confirmation pattern stored in the storage unit, the pattern detection result, the correction result, and the conference holding information of the main conference are associated (S414).

The confirmation pattern in which the association is performed, and the pattern detection result and the correction result are transmitted to the database server 510 (S415). If a response signal to the information transmitted from the database server 510 cannot be received (No in S416), that is, if transmission is not possible, transmission is repeated at a predetermined interval until transmission is possible.
When the transmission of the confirmation pattern, the pattern detection result, and the correction result to the database server 510 is completed (Yes in S416), the confirmation pattern of the main meeting and the pattern detection result stored in the storage unit of the portable information terminal 301 The correction result is deleted (S417).
Next, a processing flow of the projector 100 will be described.

(Projector flow)
As shown in FIG. 23, the projector 100 first receives information related to each image configuration, a confirmation pattern for each image configuration, and its interrupt timing from the operator's portable information terminal 301 (S501). If this reception is not possible (No in S502), the reception standby state is maintained until the information can be received.
If the information is received (Yes in S502), the received image configuration, the confirmation pattern for each image configuration, and information related to the interrupt timing are stored in the storage unit of the projector 100 (S503).

When image projection is started, the image signal input from a personal computer or the like is compared with the stored image information for inputting each image configuration, and a confirmation pattern for each image configuration is interrupted in the image information and projected at the interrupt timing. (S504).
A confirmation pattern for each image configuration projected and interrupted is detected by the pattern detection means (S505), and an adjustment amount is calculated by the projection setting calculation means included in the projector 100 for each confirmation pattern of each projected image configuration. (S506). Further, the calculated adjustment amount is also stored in the storage means (S507).

  Based on the adjustment amount stored in the storage unit, the projection setting adjustment unit adjusts the projection setting for each image configuration (S508). Then, the projection time of the projected image is confirmed (S509), and when the image projection has not ended (No in S510), the projection of the confirmation pattern (S504) described above is performed for each image configuration for each image configuration. Repeat the adjustment (S507). Thereafter, when the image projection is completed (Yes in S510), the detection result of the confirmation pattern for each image configuration and the correction result of the projection image are transmitted to the portable information terminal 301 of the operator (S511). Thereafter, when a response signal to the information transmitted from the portable information terminal 301 of the operator cannot be received (No in S512), that is, when transmission is not possible, transmission is repeated at a predetermined interval until transmission is possible.

  And if the response signal with respect to the information transmitted from the portable information terminal 301 is received, that is, if transmission is possible (Yes in S512), the confirmation pattern of the main meeting, the detection result of the confirmation pattern stored in the storage unit of the projector 100, and The correction result is deleted (S513).
