Description

  The present invention relates to an image projection system, an information processing apparatus, an image projection method, and a program.

  In recent years, digital signage that distributes content such as moving images to an image projection apparatus such as a projector and projects the content on a large screen installed outdoors, in a store, in a public space or the like has been widely used. In the case of digital signage, content suitable for time and place can be projected in real time, so a high advertising effect can be expected.

  On the other hand, in the case of large-scale digital signage using the image projection apparatus as described above, a flat surface having a certain size is required as a projection target. For this reason, there is a problem that the applicable places are limited. In contrast, for example, if one digital signage can be realized by combining a plurality of surfaces included in a predetermined area, such as a window glass (light transmission surface) of a building, the digital signage The application range can be expanded. In particular, if it can be applied to medium- and high-rise buildings with a large number of window glasses, digital signage on a larger scale than before can be realized.

  Here, when digital signage is realized by combining a plurality of window glasses, it is necessary to project a moving image for projection according to each position on an image projection device arranged corresponding to each window glass. For this reason, the number of projection moving images to be generated increases, and high operability is required in handling the projection moving images (various operations such as distribution, projection, and deletion). On the other hand, since it takes a lot of time to generate a moving image for projection, if an operator deletes it by mistake, it takes time to regenerate, and digital signage cannot be performed for a certain period of time. .

  For this reason, it is desirable to prevent the occurrence of erroneous operations while maintaining high operability in the management of projection moving images.

  The present invention has been made in view of the above problems, and an object of the present invention is to prevent erroneous operations in digital signage in which a plurality of surfaces are combined.

<5. Information stored in each management unit>
Next, various information (signage target information, image information, schedule information) stored in each management unit (signage target information management unit 375, image information management unit 376, schedule information management unit 377) of the information processing device 370 will be described. To do.

(1) Signage target information First, the signage target information stored in the signage target information management unit 375 will be described. FIG. 5 is a diagram illustrating an example of signage target information. As shown in FIG. 5A, the signage target information 500 is generated for each signage target. In this embodiment, the signage target ID of the building 110 is “S001”.

  Further, as shown in FIG. 5A, the signage target information 500 includes information items such as “floor”, “window ID”, “window information”, “projector ID”, “motorized screen ID”, “ The illumination device ID "is included.

  The “floor” stores the floor number of the floor to which the window glass group 120 included in the predetermined area on the outer surface of the building 110 is attached.

  The “window ID” stores an identifier for identifying each window glass of the window glass group 120 included in a predetermined area on the outer surface of the building 110.

  The “window information” further includes “position”, “horizontal size”, and “vertical size”. Here, the “position”, “horizontal size”, and “vertical size” of each window glass included in the “window information” will be described with reference to FIG.

  As illustrated in FIG. 5B, the image projection system 300 realizes large-scale digital signage using a predetermined area 510 on the outer surface of the building 110. At this time, the image projection system 300 defines a reference point (origin) and a reference axis (x axis, y axis) when specifying the layout of each window glass included in the predetermined area 510.

  In FIG. 5B, a point 520 indicates the origin in the predetermined area 510. An axis 530 indicates the x axis when the point 520 is the origin in the predetermined area 510, and an axis 540 indicates the y axis when the point 520 is the origin in the predetermined area 510.

In the case of FIG. 5A, the coordinates of the position of the lower left corner of the window glass of window ID = “W201” are the origin (0, 0).

The “horizontal size” stores the length (width) of each window glass in the horizontal direction. For example, in the case of the window glass with window ID = “W201”, the coordinates of the position of the lower left corner are (0, 0), and the coordinates of the position of the lower right corner are (x ₁₂ , 0). Therefore, the horizontal size = “x ₁₂ ”. In the case of the window glass with window ID = “W202”, the coordinates of the position of the lower left corner are (x ₂₁ , 0), and the coordinates of the position of the lower right corner are (x ₂₂ , 0). Therefore, the horizontal size = “x ₂₂ −x ₂₁ ”.

The “vertical size” stores the length (height) of each window glass in the vertical direction. For example, in the case of the window glass with window ID = “W201”, the coordinates of the position of the lower left corner are (0, 0), and the coordinates of the position of the upper left corner are (0, y ₁₂ ). Therefore, the vertical size = “y ₁₂ ”. In the case of the window glass with window ID = “W301”, the coordinates of the lower left corner position are (0, y ₂₁ ), and the coordinates of the upper left corner position are (0, y ₂₂ ). Therefore, the vertical size = “y ₂₂ −y ₂₁ ”.

  “Projector ID” stores an identifier for identifying a projector arranged at a position corresponding to each window glass. In the example of FIG. 5A, projectors identified by projector ID = “PJ201A” and “PJ201B” are respectively arranged at positions corresponding to the window glass identified by window ID = “W201”.

Is shown.

  The “window ID” stores an identifier for identifying each window glass of the window glass group 120 included in the predetermined area 510 on the outer surface of the building 110 identified by the signage target ID = “S001”.

  The “projector ID” stores an identifier for identifying a projector disposed at a position corresponding to each window glass identified by the window ID.

  The “correction parameter ID” stores an identifier for identifying the correction parameter calculated by the calibration unit 371. As described above, since the calibration unit 371 calculates a correction parameter for each window glass by executing the first calibration process, the correction parameter ID is stored in association with the window ID. The “calculation date / time” stores the date / time when the correction parameter was calculated.

  The “divided still image group ID” is a divided still image generated in the process of generating each projection moving image group based on the moving images identified by the moving image IDs “C100” to “C105”. An identifier for identifying the image group is stored.

  In the “projection moving image ID”, each of the projection moving images included in each of the projection moving image groups generated based on the moving images identified by the moving image ID = “C100” to “C105”. An identifier for identifying is stored.

  In “generation date and time”, the date and time when each projection moving image identified by the projection moving image ID is generated is stored.

  The example of FIG. 6 shows that the moving image IDs for projection = “M201A”, “M201B”,... “M705B” are generated from the moving images with the moving image ID = “C100” to “C105”, respectively. ing.

  Further, according to the example of FIG. 6, the projection moving image with the projection moving image ID = “M201A” associated with the moving image ID = “C100” corresponds to the window glass with the window ID = “W201”. Projection is performed by the projector with the projector ID = “PJ201A” arranged at the position.

  Further, according to the example of FIG. 6, when generating the projection moving image with the projection moving image ID = “M201A” associated with the moving image ID = “C100”, “May 25, 2016” is set. A correction parameter (correction parameter ID = “P201”) is calculated.

  Further, according to the example of FIG. 6, the divided still image group of the divided still image group ID = “C201” is corrected by the correction parameter (correction parameter ID = “P201”). Further, according to the example of FIG. 6, based on the divided still image group with the corrected divided still image group ID = “C201”, the projection moving image ID = “M201A” on “June 10, 2016”. And “M201B” projection moving images are generated.

As shown in FIGS. 7A to 7C, the schedule information 710 to 730 includes “time” and “signage device” as information items.

  In “Time”, a time zone in which the window glass group 120 of the building 110 identified by the signage target ID = “S001” can be used as digital signage is described. 7A to 7C, the digital signage can be used in a time zone from 10:00 to 22:00.

  FIG. 11 is a diagram illustrating an example of a screen of the information processing apparatus displayed during the first calibration process. When the first calibration unit 911 is activated, a selection screen 1100 is displayed on the display unit 405 of the information processing device 370. As shown in FIG. 11, the selection screen 1100 includes a layout 1110 of the window glass group 120 of the building 110.

  The operator 1000 selects a window glass on which a target for executing the first calibration process is arranged by pressing a rectangular button indicating the window glass in the layout 1110 and pressing a completion button 1120. The example of FIG. 11 shows a state where the rectangular button 1111 is pressed and the completion button 1120 is pressed.

  In step S1009, the projector 310_28a projects the first calibration pattern image transmitted from the first calibration unit 911. In step S1010, the projector 310_28b projects the second calibration pattern image transmitted from the first calibration unit 911.

  In step S <b> 1011, the operator 1000 inputs an imaging instruction to the imaging device 381 in order to capture the projected first and second calibration pattern images using the imaging device 381.

  In step S1012, the imaging device 381 performs imaging processing on the projected first and second calibration pattern images, and in step S1013, the imaging device 381 transmits the imaging result to the information processing device 370.

  FIG. 12 is a diagram illustrating an example of a calibration pattern image projected during the first calibration process. As shown in FIG. 12, the projector 310_28a projects the first calibration pattern image, and the projector 310_28b projects the second calibration pattern image. The operator 1000 captures the projected first and second calibration pattern images using the imaging device 381, and transmits the imaging result to the information processing device 370.

  Returning to the description of FIG. In step S1014, the operator 1000 inputs an exchange instruction for exchanging the first calibration pattern image and the second calibration pattern image.

  In step S1015, the first calibration unit 911 transmits the second calibration pattern image to the projector 310_28a in response to the replacement instruction. In step S1016, the first calibration unit 911 transmits the first calibration pattern image to the projector 310_28b.

  In step S1017, the projector 310_28a projects the second calibration pattern image transmitted from the first calibration unit 911. In step S1018, the projector 310_28b projects the first calibration pattern image transmitted from the first calibration unit 911.

  In step S <b> 1019, the operator 1000 inputs an imaging instruction to the imaging device 381 in order to capture the projected second and first calibration pattern images using the imaging device 381.

  In step S1020, the imaging device 381 performs imaging processing on the projected second and first calibration pattern images. In step S1021, the imaging device 381 transmits the imaging result to the information processing device 370.

  FIG. 13 is a diagram illustrating another example of the calibration pattern image projected during the first calibration process. As shown in FIG. 13, the projector 310_28a projects the second calibration pattern image, and the projector 310_28b projects the first calibration pattern image. The operator 1000 captures the projected second and first calibration pattern images using the imaging device 381, and transmits the imaging result to the information processing device 370.

  Returning again to the description of FIG. In step S <b> 1022, the operator 1000 inputs to the first calibration unit 911 to specify the imaging result used for calculating the correction parameter. In step S <b> 1023, the first calibration unit 911 reads the imaging result designated by the operator 1000.

  In step S1024, the operator 1000 performs input for instructing calculation of the correction parameter. In step S1025, the first calibration unit 911 calculates a correction parameter based on the read imaging result.

  The correction parameters calculated by the first calibration unit 911 include various geometric corrections such as alignment correction, scale alignment correction, and distortion correction for the first and second calibration pattern images. Geometric parameters are included. This geometric parameter varies depending on various factors such as an installation position of the electric screen and the projection apparatus, and individual differences between optical apparatuses of the projection apparatus. For this reason, geometric parameters often differ for each window glass (combination of a motorized screen and a projection device). In an image processing unit 372 to be described later, by performing correction using an appropriate geometric parameter for each window glass, a part of the projection moving image in the projection moving image group 130 projected as shown in FIG. 1 is obtained. Avoid the occurrence of problems such as distorted display.

  The first calibration unit 911 stores the calculated correction parameter in the image information management unit 376. In addition, the first calibration unit 911 associates the correction parameter ID (for example, “P703”) and the calculation date (for example, “2016.5.25”) with the window ID (for example, “W703”) to generate an image. Stored in information 600.

(3) Flow of Second Calibration Process Next, the details of the second calibration process will be described based on the sequence diagram of FIG. 14 with reference to FIG. FIG. 14 is a sequence diagram of the second calibration process.

  As illustrated in FIG. 14, in step S <b> 1401, the operator 1000 inputs an activation instruction for activating the second calibration unit 912 to the information processing apparatus 370.

  In response to the activation instruction being input by the operator 1000, in step S1402, the second calibration unit 912 is activated, and the display unit 405 of the information processing device 370 is subject to the second calibration process (projector). ) Is displayed for the operator 1000 to select.

  In step S1403, the operator 1000 selects, from the selection screen displayed on the display unit 405, the window glass on which the target for executing the second calibration process is arranged.

  In response to the window glass being selected by the operator 1000, the second calibration unit 912 identifies the motorized screen disposed at a position corresponding to the selected window glass. In step S1404, the second calibration unit 912 transmits a screen OFF instruction to the identified electric screen.

  The example in FIG. 14 shows a case where the window glass 1128 with the window ID = “W703” is selected and the screen OFF instruction is transmitted to the corresponding electric screen 330_28, as in the first calibration process. .

  In response to the screen OFF instruction transmitted from the second calibration unit 912, the electric screen 330_28 is turned off in step S1405.

  In step S1406, the second calibration unit 912 transmits a lamp ON instruction to the projector 310_28a (projector ID = “PJ703A”) disposed at the position corresponding to the window glass 1128 with the window ID = “W703”. Thereby, the lamp of the projector n′310_28a is turned on.

  In step S1407, the operator 1000 inputs a projection instruction for projecting a white image to the projector 310_28a to the information processing apparatus 370.

  In step S1408, the second calibration unit 912 transmits a white image projection instruction to the projector 310_28a in response to the white image projection instruction from the operator 1000.

  In step S1409, the projector 310_28a performs all white projection according to the white image projection instruction transmitted from the second calibration unit 912.

  In step S1410, the operator 1000 inputs, to the color luminance meter 382, a measurement instruction for measuring the color temperature of the window glass projected by the projector 310_28a.

  In step S1411, the color luminance meter 382 measures the color temperature of the window glass 1128 projected all white. In step S1412, the operator 1000 inputs the measured color temperature as a measurement result to the information processing device 370.

  In step S1413, the second calibration unit 912 performs a conversion process for converting the color temperature input by the operator 1000 into an RGB level.

  In step S1414, the second calibration unit 912 transmits the RGB level calculated by performing the conversion process to the projector 310_28a.

  In step S1415, the projector 310_28a sets the RGB level transmitted from the second calibration unit 912.

  FIG. 15 is a diagram illustrating an example of a white image projected during the second calibration process. As shown in FIG. 15, the projector 310_28a projects a white image onto the window glass 1128 when the electric screen 330_28 is in the OFF state. The operator 1000 measures the color temperature of the window glass 1128 using the color luminance meter 382 and inputs the measurement result to the information processing device 370. Thereby, the information processing device 370 calculates the RGB level, and the projector 310_28a is set with the RGB level corresponding to the measurement result.

  Returning to the description of FIG. In step S1416, the operator 1000 inputs an instruction to end the second calibration process to the information processing apparatus 370. In step S1417, the second calibration unit 912 transmits a screen ON instruction to the electric screen 330_28 in response to the end instruction input by the operator 1000.

  In response to the screen ON instruction transmitted from the second calibration unit 912, the electric screen 330_28 is turned on in step S1418.

<8. Details of image processing>
Next, details of the image processing (step S802) in the image projection system 300 will be described.

(1) Functional Configuration of Image Processing Unit First, a functional configuration of the image processing unit 372 of the information processing apparatus 370 that executes image processing will be described. FIG. 16 is a diagram illustrating a functional configuration of the image processing unit of the information processing apparatus.

  As illustrated in FIG. 16, the image processing unit 372 includes a target information acquisition unit 1611, an image information acquisition unit 1612, an inversion unit 1613, and a decoding unit 1614. The image processing unit 372 includes a first dividing unit 1615, a correcting unit 1616, a second dividing unit 1617, an encoding unit 1618, and a transmitting unit 1619.

  The target information acquisition unit 1611 reads the signage target information from the signage target information management unit 375 and notifies the first division unit 1615 of it.

  The image information acquisition unit 1612 reads the moving image provided by the advertiser from the image information management unit 376 and notifies the reversing unit 1613 of the moving image.

  The inversion unit 1613 inverts the left and right of the moving image notified from the image information acquisition unit 1612. In the image projection system 300, a transparent or translucent light transmission surface (window glass and motorized screen) is projected from the inside, and the projection result is visually recognized from the outside. For this reason, it is necessary to reverse the left and right in advance. As described above, the reversing unit 1613 performs the reversing process, so that it is possible to avoid a situation in which a moving image whose left and right are reversed from the moving image intended by the advertiser is visually recognized. The inversion unit 1613 notifies the decoding unit 1614 of the video image after inversion.

  The decoding unit 1614 extracts a still image group by performing a decoding process on the moving image for which left and right are determined and decomposing the moving image into frame units. The decoding unit 1614 notifies the first dividing unit 1615 of each still image included in the extracted still image group in order.

  The first division unit 1615 performs a first division process for dividing each still image sequentially notified from the decoding unit 1614 into a plurality of still images based on the signage target information 500 notified from the target information acquisition unit 1611. . Thereby, the 1st division part 1615 can generate | occur | produce the division | segmentation still image (division image) according to the position of the window glass, and the size of the window glass.

  In addition, the first dividing unit 1615 divides a plurality of divided still images obtained by performing the first dividing process on all the still images included in the still image group for each divided still image of the same window glass. Thus, a plurality of divided still image groups corresponding to the number of window glasses are generated. The first dividing unit 1615 stores the generated plurality of divided still image groups in the image information management unit 376.

  Further, the first dividing unit 1615 attaches a divided still image group ID to each of the generated plurality of divided still image groups, and stores them in the image information 600 in association with the window IDs.

  Furthermore, the first dividing unit 1615 notifies the correcting unit 1616 of each of the generated plurality of divided still image groups in association with the window ID.

  The correcting unit 1616 corrects each of the plurality of divided still image groups notified from the first dividing unit 1615 using the correction parameter corresponding to the window ID. In addition, the correction unit 1616 notifies the second divided unit 1617 of the plurality of divided still image groups after correction.

  The second dividing unit 1617 divides each of the corrected plurality of divided still image groups notified from the correcting unit 1616 into units of projectors. Since the plurality of divided still image groups after correction notified by the correction unit 1616 are generated in window glass units, the second division unit 1617 divides them into projector units.

  The encoding unit 1618 encodes a plurality of corrected still image groups divided for each projector in units of projectors, and generates a plurality of projection moving images corresponding to the number of projectors. The encoding unit 1618 stores, in the image information 600, the projection moving image ID for identifying the generated plurality of projection moving images and the generation date and time in association with the projector ID.

  The transmission unit 1619 transmits the plurality of projection moving images generated by the encoding unit 1618 to the corresponding projectors. In addition, since the transmission unit 1619 transmits the projection moving image to the corresponding projector in advance, the signage control unit 373 only needs to transmit a projection start instruction to the projector at the start of projection. . Accordingly, it is possible to reduce the possibility of delay in projecting the projection moving image, as compared with the case where the projection moving image is transmitted to the projector at the start of projection.

(2) Specific Example of Image Processing Next, a specific example of image processing by the image processing unit 372 will be described. FIG. 17 is a diagram illustrating a specific example of image processing. Here, image processing for generating “content 100” will be described.

  In FIG. 17, a moving image 1710 is a moving image with a moving image ID = “C100” provided by an advertiser, and is stored in the image information management unit 376 in the MPEG4 format. When the image information acquisition unit 1612 reads the moving image 1710 and notifies the reversing unit 1613, the reversing unit 1613 inverts the left and right of the moving image 1710 and generates a reversed moving image 1711.

  The inverted moving image 1711 is decoded by the decoding unit 1614 and extracted as a still image group including a plurality of still images. Further, for the extracted still image group, the first dividing unit 1615 performs a first dividing process based on the signage target information 500 to generate a plurality of divided still image groups.

  A plurality of divided still image groups (divided still image groups 1720_1, 1720_2,... 1720_30) are each assigned a divided still image group ID (C201, C202,... C705), and correspond to a window ID. In addition, the image information 600 is stored.

  In addition, the correction unit 1616 corrects each of the plurality of divided still image groups 1720_1, 1720_2, ... 1720_30 using the corresponding correction parameter. For example, the correction unit 1616 corrects the divided still image group 1720_1 using the correction parameter 1730_1 (correction parameter ID = “P201”). The correction unit 1616 corrects the divided still image group 1720_2 using the correction parameter 1730_2 (correction parameter ID = “P202”). Further, the correction unit 1616 corrects the divided still image group 1720_30 using the correction parameter 1730_30 (correction parameter ID = “P705”).

  The corrected divided still image groups 1720_1, 1720_2,... 1720_30 corrected by the correction parameters are each divided into projector units by the second dividing unit 1617. For example, the corrected divided still image group 1720_1 is divided into a divided still image group 1740_1a for the projector 310_1a and a divided still image group 1740_1b for the projector 310_1b.

  Similarly, the corrected divided still image group 1720_30 is divided into a divided still image group 1740_30a for the projector 310_30a and a divided still image group 1740_30b for the projector 310_30b.

  The encoding unit 1618 performs an encoding process on the corrected divided still image groups 1740_1a to 1740_30b divided into projectors by the second dividing unit 1617. As a result, the encoding unit 1618 generates a moving image for projection in the MPEG4 format.

  For example, the encoding unit 1618 encodes the divided still image group 1740_1a for the projector 310_1a to generate the projection moving image 1750_1a. The encoding unit 1618 generates a projection moving image 1750_1b by encoding the divided still image group 1740_1b for the projector 310_1b. Further, the encoding unit 1618 encodes the divided still image group 1740_30a for the projector 310_30a and the divided still image group 1740_30b for the projector 310_30b to generate projection moving images 1750_30a and 1750_30b. As a result, “content 100” is generated.

  The encoding unit 1618 associates the generated projection moving images 1750_1a to 1750_30b with the projection moving image IDs (M201A, M201B,... M705A, M705B) and the generation date and time with the projector ID. Stored in information 600.

  In addition, the transmission unit 1619 transmits the generated plurality of projection moving images 1750_1a to 1750_30b to the corresponding projector. For example, the transmission unit 1619 transmits the projection moving image 1750_1a to the projector 310_1a. In addition, the projection moving image 1750_1b is transmitted to the projector 310_1b. Further, the transmission unit 1619 transmits the projection moving image 1750_30a to the projector 310_30a, and the projection moving image 1750_30b to the projector 310_30b.

(3) Flow of Image Processing Next, the flow of image processing will be described based on the flowchart of FIG. FIG. 18 is a flowchart showing the flow of image processing.

  In step S <b> 1801, the image information acquisition unit 1612 acquires a moving image from the image information management unit 376.

  In step S1802, the target information acquisition unit 1611 acquires the signage target information 500 from the signage target information management unit 375.

  In step S1803, the reversing unit 1613 performs left-right reversing processing on the moving image acquired in step S1801.

  In step S1804, the decoding unit 1614 extracts a still image group by decoding the inverted moving image.

  In step S1805, the first dividing unit 1615 substitutes 1 for the still image counter n.

  In step S1806, the first division unit 1615 performs the first division process on the nth still image. Details of the flowchart of the first division process will be described later.

  In step S1807, the first division unit 1615 determines whether or not the first division process has been performed for all still images. If it is determined in step S1807 that there is a still image that has not been subjected to the first division processing (in the case of No in step S1807), the process proceeds to step S1808. In step S1808, the first dividing unit 1615 increments the still image counter n, and then returns to step S1806.

  On the other hand, if it is determined in step S1807 that the first division process has been performed for all still images, the process advances to step S1809.

  In step S1809, the first dividing unit 1615 generates divided still image groups for the number of window glasses by dividing the plurality of divided still images generated for each still image into divided still images corresponding to the same window glass. And stored in the image information management unit 376. Further, the first dividing unit 1615 attaches a divided still image group ID to each generated divided still image group and stores it in the image information 600 in association with the window ID.

  In step S1810, the correction unit 1616 substitutes 1 for the divided still image group counter m.

  In step S1811, the correction unit 1616 corrects the mth divided still image group among the divided still image groups generated in step S1809, using the corresponding correction parameter.

  In step S1812, the second dividing unit 1617 performs the second dividing process on the m-th divided still image group after correction.

  In step S1813, the second dividing unit 1617 determines whether correction processing and second division processing have been performed for all the divided still image groups generated in step S1809.

  If it is determined in step S1813 that there is a divided still image group that has not been subjected to the correction process and the second division process (in the case of No in step S1813), the process proceeds to step S1814.

  In step S1814, the correction unit 1616 increments the divided still image group counter m, and the process returns to step S1811.

  On the other hand, if it is determined in step S1813 that correction processing and second division processing have been performed for all divided still image groups (Yes in step S1813), the process proceeds to step S1815.

  In step S <b> 1815, the encoding unit 1618 generates a plurality of projection moving images (contents) corresponding to the number of projectors by encoding the divided still image group subjected to the second division processing in units of projectors. Also, the encoding unit 1618 stores the generation date and time in the image information 600 for the generated plurality of projection moving images (contents).

  In step S1816, the transmission unit 1619 transmits the generated plurality of projection moving images to the corresponding projectors.

(4) Details of First Division Processing Next, details of the first division processing (step S1806) will be described using FIG. 19 and FIG. FIG. 19 is a flowchart showing the flow of the first division process. FIG. 20 is a diagram illustrating an example of the first division process.

  In step S1901, the first dividing unit 1615 reads the nth still image. In FIG. 20, a still image 2000 is assumed to be the nth still image read by the first dividing unit 1615.

  In step S1902, the first dividing unit 1615 substitutes “2” for the floor counter f.

  In step S1903, the first dividing unit 1615 substitutes “1” for the window counter g that counts the number of window glasses per floor.

In step S1904, the first dividing unit 1615 reads the “position”, “horizontal size”, and “vertical size” of the window ID = “Wf0g” from the signage target information 500. Here, since “2” is assigned to f and “1” is assigned to g, the position of window ID = “W201” ((0, 0)), horizontal size (x ₁₂ ), vertical size ( y ₁₂ ) is read out.

  In step S1905, the first dividing unit 1615 converts the position, horizontal size, and vertical size read in step S1904 into pixels on the still image 2000 according to the comparison between the still image 2000 and the predetermined area 510.

  As shown in FIG. 20, in the present embodiment, the still image 2000 is assumed to be composed of 4000 pixels horizontally and 8000 pixels vertically. In this case, the pixel on the still image 2000 corresponding to the position = “(0, 0)” is the pixel at the position = “(0, 0)”.

In addition, the pixel on the still image 2000 corresponding to the horizontal size (x ₁₂ ) is a pixel calculated by (x ₁₂ / x ₅₂ ) × 4000. Furthermore, the pixel on the still image 2000 corresponding to the vertical size (y ₁₂ ) is a pixel calculated by (y ₁₂ / y ₆₂ ) × 8000.

  In step S1906, the first dividing unit 1615 cuts out the rectangular area 2001 specified based on the pixel calculated in step S1905 from the still image 2000, and generates a divided still image.

  In step S1907, the 1st division part 1615 determines whether the 1st division process was performed about all the windowpanes of f floor. If it is determined in step S1907 that there is a window glass that has not been subjected to the first division process (in the case of No in step S1907), the process proceeds to step S1908.

  In step S1908, the first dividing unit 1615 increments the window counter g, and then returns to step S1904. As a result, “2” is substituted for g.

In step S1904, the first dividing unit 1615 determines, based on the signage target information 500, the position of window ID = “W202” ((x ₂₁ , 0)), the horizontal size (x ₂₂ −x ₂₁ ), and the vertical size (y ₁₂ ). Is read.

  In step S1905, the first dividing unit 1615 converts the position, horizontal size, and vertical size read in step S1904 into pixels on the still image 2000.

As shown in FIG. 20, the pixel on the still image 2000 corresponding to the position ((x ₂₁ , 0)) is a pixel calculated by (x ₂₁ / x ₅₂ ) × 4000. In addition, the pixel on the still image 2000 corresponding to the horizontal size (x ₂₂ −x ₂₁ ) is a pixel calculated by (x ₂₂ / x ₅₂ ) × 4000. Furthermore, the pixel on the still image 2000 corresponding to the vertical size (y ₁₂ ) is a pixel calculated by (y ₁₂ / y ₆₂ ) × 8000.

  In step S1906, the first dividing unit 1615 cuts out the rectangular region 2002 specified based on the pixel calculated in step S1905 from the still image 2000, and generates a divided still image.

  In step S1907, the 1st division part 1615 determines whether the 1st division process was performed about all the windowpanes of f floor. If it is determined in step S1907 that there is a window glass that has not been subjected to the first division process (in the case of No in step S1907), the process proceeds to step S1908. Thereafter, in step S1906, the processes in steps S1904 to S1906 are repeated until the rectangular area 2005 is cut out.

  If it is determined in step S1907 that the first division processing has been performed for all the windowpanes on the f floor (Yes in step S1907), the process proceeds to step S1909.

  In step S1909, the first division unit 1615 determines whether or not the first division process has been performed for all floors. If it is determined in step S1909 that there is a floor that has not been subjected to the first division process (in the case of No in step S1909), the process proceeds to step S1910.

  In step S1910, the first dividing unit 1615 increments the floor counter f, and then returns to step S1903. Thereafter, the processing in steps S1904 to S1907 is repeated until the rectangular area 2030 is cut out at the floor counter f = 7.

  If it is determined in step S1909 that the first division process has been performed for all floors (Yes in step S1909), the process returns to step S1807 in FIG.

<9. Details of signage control processing>
Next, details of the signage control process (step S803) in the image projection system 300 will be described.

(1) Functional Configuration of Signage Control Unit First, a functional configuration of the signage control unit 373 of the information processing apparatus 370 that executes the signage control process will be described. FIG. 21 is a diagram illustrating a functional configuration of a signage control unit of the information processing apparatus.

  As illustrated in FIG. 21, the signage control unit 373 includes a schedule management unit 2101, a synchronization unit 2102, a start control unit 2103, and an end control unit 2104.

  The schedule management unit 2101 functions as an operation unit that operates a schedule and content (a moving image group for projection), and executes schedule management processing.

  Specifically, the schedule management unit 2101 generates schedule information and stores it in the schedule information management unit 377. The schedule management unit 2101 edits and deletes the generated schedule information.

  In addition, the schedule management unit 2101 transmits, to the projectors 310_1a to 310_30b, an instruction to delete each projection moving image included in the projection moving image group specified by the selected content. Further, the schedule management unit 2101 rewrites the image information 600 with respect to information on each of the projection moving images instructed to be deleted when each of the projection moving images instructed of deletion is deleted by the projectors 310_1a to 310_30b.

  The synchronization unit 2102 outputs time information. Further, the synchronization unit 2102 synchronizes the time between the projectors 310_1a to 310_30b and the information processing device 370. Specifically, after receiving time information from the time server 360 and correcting the time information to be output, the corrected time information is transmitted to the projectors 310_1a to 310_30b. When the projectors 310_1a to 310_30b receive the time information from the synchronization unit 2102, the projectors 310_1a to 310_30b correct the time information managed internally. Thereby, the synchronization unit 2102 can synchronize the time between the projectors 310_1a to 310_30b and the information processing device 370 based on accurate time information.

  The start control unit 2103 reads the schedule information stored in the schedule information management unit 377 and identifies the projection start time. In addition, the start control unit 2103 transmits an operation instruction at the start of projection to each signage device based on the identified projection start time.

  The end control unit 2104 reads the schedule information stored in the schedule information management unit 377 and identifies the projection end time. In addition, the end control unit 2104 transmits an operation instruction at the end of projection to each signage device based on the identified projection end time.

(2) Flow of Signage Control Processing Next, the flow of signage control processing (step S803) by the signage control unit 373 will be described. FIG. 22 is a flowchart showing the flow of signage control processing. When the image processing by the image processing unit 372 is completed, the signage control process shown in FIG. 22 can be executed.

  In step S2201, the schedule management unit 2101 performs schedule management processing including schedule information generation, editing and deletion, content deletion, and the like. Details of the schedule management process (step S2201) will be described later.

  In step S2202, the start control unit 2103 reads schedule information (for example, schedule information 710) stored in the schedule information management unit 377 by performing the schedule management process, and identifies the projection start time.

  In step S2203, the start control unit 2103 transmits a lamp ON instruction to the projectors 310_1a to 310_30b at a timing according to the identified projection start time. Thereby, each lamp of projector 310_1a-310_30b will be in an ON state.

  In step S2204, the synchronization unit 2102 receives time information from the time server 360, corrects the time information managed in the information processing device 370, and transmits the corrected time information to the projectors 310_1a to 310_30b. To do.

  In step S2205, the start control unit 2103 identifies each projection moving image of the content specified in the schedule information to the projectors 310_1a to 310_30b at a timing according to the identified projection start time, and instructs the projection start. Send. Thereby, in the projectors 310_1a to 310_30b, a process for starting the projection of the specified projection moving image is performed.

  In step S2206, the start control unit 2103 transmits an electrical decoration OFF instruction to the electrical decoration devices 140_1 to 140_6 at a timing according to the identified projection start time. Thereby, the illumination devices 140_1 to 140_6 are turned off.

  In step S2207, the start control unit 2103 transmits a screen ON instruction to the electric screens 330_1 to 330_30 at a timing according to the identified projection start time. Thereby, each of the electric screens 330_1 to 330_30 is turned on, and the light transmission surface is translucent. Through the above processing, digital signage corresponding to one schedule information is started.

  When projection starts, in step S2208, the end control unit 2104 reads schedule information (for example, schedule information 710) stored in the schedule information management unit 377. Further, the end control unit 2104 identifies the projection end time based on the read schedule information, and determines whether or not the current time has approached the projection end time.

  If it is determined in step S2208 that the projection end time has not been approached (No in step S2208), the process waits until it is determined that the projection end time has been approached.

  On the other hand, if it is determined in step S2208 that the projection end time has been approached (Yes in step S2208), the process proceeds to step S2209.

  In step S2209, the end control unit 2104 transmits a projection end instruction to the projectors 310_1a to 310_30b at a timing according to the identified projection end time. Thus, the projectors 310_1a to 310_30b end the projection of the projection moving image.

  In step S2210, the end control unit 2104 transmits a screen OFF instruction to the electric screens 330_1 to 330_30 at a timing according to the identified projection end time. Thereby, each of the electric screens 330_1 to 330_30 is turned off, and the light transmission surface is in a transparent state.

  In step S2211, the end control unit 2104 transmits an electrical decoration ON instruction to the electrical decoration devices 140_1 to 140_6 at a timing according to the identified projection end time. Thereby, the illumination devices 140_1 to 140_6 are turned on.

  In step S2212, the end control unit 2104 transmits a lamp OFF instruction to the projectors 310_1a to 310_30b at a timing corresponding to the identified projection end time. Accordingly, the lamps of the projectors 310_1a to 310_30b are turned off. Through the above processing, digital signage corresponding to one schedule information is completed.

  In step S2213, the start control unit 2103 determines whether or not the processing from step S2202 to step S2212 has been executed for all schedule information stored in the schedule information management unit 377. If it is determined in step S2213 that there is schedule information for which the processing from step S2202 to step S2212 has not been performed (No in step S2213), the process returns to step S2202.

  On the other hand, when it is determined in step S2213 that the processes from step S2202 to step S2212 have been executed for all schedule information (in the case of Yes in step S2213), the signage control process ends.

(3) Details of Schedule Management Processing Next, details of the schedule management processing (step S2201) will be described using FIG. 23 with reference to FIGS. Here, among the schedule information stored in the schedule information management unit 377, a schedule management process mainly for a schedule (projection schedule) related to projection by the projectors 310_1a to 310_30b will be described.

  FIG. 23 is a flowchart showing the flow of the schedule management process. With respect to the projection schedule, when the operator 1000 inputs an activation instruction of the schedule management unit 2101, the flowchart shown in FIG. 23 is executed.

  In step S <b> 2301, the schedule management unit 2101 determines whether the operator 1000 has input a start / stop instruction for the schedule management unit 2101 for the projection schedule. If it is determined in step S2301 that a start / stop instruction has not been input (No in step S2301), the process proceeds to step S2302.

  In step S2302, the schedule management unit 2101 reads an identifier (for example, a file name) for identifying a projection schedule included in each of the schedule information 710 to 730 stored in the schedule information management unit 377.

  In step S2303, the schedule management unit 2101 displays a projection schedule screen on the display unit 405, and displays a list of read projection schedule file names.

  In step S2304, the schedule management unit 2101 determines whether a new registration instruction has been input by the operator 1000. If it is determined in step S2304 that a new registration instruction has been input (Yes in step S2304), the process proceeds to step S2305.

  In step S2305, the schedule management unit 2101 displays a new registration screen on the display unit 405. FIG. 24 is a diagram illustrating an example of a projection schedule screen and a new registration screen.

  As shown in FIG. 24A, the projection schedule screen 2400 includes a new registration button 2401 and a projection schedule list 2402. The example of FIG. 24A shows a state before schedule information 710 to 730 and the like are stored in the schedule information management unit 377. For this reason, nothing is displayed in the projection schedule list 2402.

  When a new registration instruction is input by pressing the new registration button 2401 by the operator 1000 on the projection schedule screen 2400, a new registration screen 2410 shown in FIG. 24B is displayed on the display unit 405. Is done.

  As shown in FIG. 24B, the new registration screen 2410 includes a name input field 2411, a start time / end time input field 2412, a day of week specification field 2413, and a content display field 2414.

  In the name input field 2411, the file name of the projection schedule is input. In the start time and end time input field 2412, a projection start time at which the projectors 310_1a to 310_30b start projecting each projection moving image and a projection end time at which the projection of each projection moving image ends are input. In the day of the week designation field 2413, the day of the week on which each projection moving image is projected is designated. In the content display field 2414, the content name of the content specifying each projection moving image projected by the projectors 310_1a to 310_30b is displayed.

  In a state where the new registration screen 2410 is displayed, the operator 1000 performs input in each of the name input field 2411, the start time / end time input field 2412, the day of week specification field 2413, and the content display field 2414.

  In step S <b> 2306, the schedule management unit 2101 performs new registration processing that accepts these inputs by the operator 1000.

  Thereafter, on the new registration screen 2410, the operator 1000 presses the registration button 2415, whereby the new registration process is completed. Thereby, the schedule management unit 2101 stores the newly generated projection schedule in the schedule information of the schedule information management unit 377, and the process returns to step S2301. Thereby, the projection schedule in which the content to be projected, the time zone to project, and the like are designated as the projection schedule is stored. When the operator 1000 presses the return button 2416 on the new registration screen 2410, the schedule management unit 2101 returns to step S2301 without storing the projection schedule.

  On the other hand, if it is determined in step S2304 that a new registration instruction has not been input (No in step S2304), the process proceeds to step S2307.

  In step S2307, the schedule management unit 2101 determines whether a projection schedule is designated by the operator 1000 and an instruction to edit the designated projection schedule is input. If it is determined in step S2307 that a projection schedule has been designated and an instruction to edit the designated projection schedule has been input (Yes in step S2307), the process advances to step S2308.

  In step S2308, the schedule management unit 2101 displays a schedule edit screen. FIG. 25 is a diagram illustrating an example of a projection schedule screen and a schedule editing screen.

  As shown in FIG. 25A, the projection schedule list 2402 on the projection schedule screen 2400 displays the file names of the projection schedules included in the schedule information 710 to 730 stored in the schedule information management unit 377. The example of FIG. 25A shows a state where “schedule_C100” to “schedule_C103” are displayed as file names of the projection schedule.

  When the operator 1000 specifies a file name of one projection schedule from the projection schedule list 2402 and presses the edit button 2502, the schedule management unit 2101 determines that an instruction to edit the projection schedule has been input. Here, as shown in FIG. 25A, it is assumed that the operator 1000 designates file name = “schedule_C102” in the projection schedule list 2402 and presses the edit button 2502. As a result, the schedule editing screen 2510 shown in FIG.

  As shown in FIG. 25B, the schedule edit screen 2510 includes a name input field 2411, a start time and end time input field 2412, a day of week specification field 2413, and a content display field 2414.

  The name input field 2411 displays the file name of the designated projection schedule (“Schedule_C102”). The start time and end time input field 2412 displays the projection start time and the projection end time of the designated projection schedule. The day of the week designated in the designated projection schedule is displayed in the day of the week designation column 2413. The content display field 2414 displays the content name (identifier) of the content scheduled to be projected in the designated projection schedule.

  In step S2309, the operator 1000 performs a schedule editing process by editing each column of the displayed schedule editing screen 2510.

  Thereafter, when the operator 1000 presses the registration button 2415, the schedule editing process is completed. Thereby, the schedule management unit 2101 stores the edited projection schedule in the schedule information of the schedule information management unit 377, and the process returns to step S2301. When the operator 1000 presses the return button 2416 on the schedule editing screen 2510, the schedule management unit 2101 returns to step S2301 without storing the edited projection schedule.

  On the other hand, if it is determined in step S2307 that an instruction to edit the designated projection schedule has not been input (No in step S2307), the process proceeds to step S2310.

  In step S2310, the schedule management unit 2101 determines whether the operator 1000 has designated a projection schedule and an instruction to delete the designated projection schedule has been input. If it is determined in step S2310 that a projection schedule has been specified and an instruction to delete the specified projection schedule has been input (Yes in step S2310), the process proceeds to step S2311.

  In step S2311, the schedule management unit 2101 performs schedule deletion processing, deletes the designated projection schedule from the schedule information of the schedule information management unit 377, and then returns to step S2301. Details of the schedule deletion process (step S2311) will be described later.

  On the other hand, if it is determined in step S2310 that an instruction to delete the designated projection schedule has not been input (No in step S2310), the process proceeds to step S2312.

  In step S2312, the schedule management unit 2101 determines whether a content deletion instruction has been input. If it is determined in step S2312 that a content deletion instruction has been input (Yes in step S2312), the process proceeds to step S2313.

  In step S2313, the schedule management unit 2101 performs content deletion processing, and transmits a deletion instruction to the projectors 310_1a to 310_30b so as to delete the projection moving image specified by the content with the selected content name. In addition, the schedule management unit 2101 rewrites the image information 600 with the deletion of the projection moving image. When the content deletion process in step S2313 is completed, the process returns to step S2301. Details of the content deletion process (step S2313) will be described later.

  On the other hand, if it is determined in step S2312 that the content deletion instruction has not been input (No in step S2312), the process directly returns to step S2301.

  Thereafter, the processes in steps S2302 to S2313 are repeated until it is determined in step S2301 that an activation stop instruction has been input. If it is determined in step S2301 that the operator 1000 has input a start / stop instruction to the schedule management unit 2101, the schedule management process ends.

(4) Details of Schedule Deletion Process Next, details of the schedule deletion process (step S2311) will be described with reference to FIGS. FIG. 26 is a flowchart showing the flow of schedule deletion processing. FIG. 27 is a diagram illustrating a state in which the schedule deletion process is performed on the projection schedule screen.

  As shown in FIG. 27A, the projection schedule list 2402 of the projection schedule screen 2400 displays the file names of the projection schedules included in the schedule information 710 to 730 stored in the schedule information management unit 377. The example of FIG. 27A shows a state where “schedule_C100” to “schedule_C103” are displayed as the file names of the projection schedule.

  When the operator 1000 specifies the file name of one projection schedule from the projection schedule list 2402 and presses the delete button 2701, the schedule management unit 2101 determines that an instruction to delete the specified projection schedule has been input. Here, it is assumed that in the projection schedule list 2402, the operator 1000 presses the delete button 2701 after specifying file name = “schedule_C103”.

  As a result, the schedule management unit 2101 executes the schedule deletion process of FIG. Specifically, in step S2601, the schedule management unit 2101 determines whether the designated projection schedule is currently being executed. The schedule management unit 2101 determines whether or not the projection schedule (“Schedule_C103”) is being executed based on whether or not the current time is a time zone between the projection start time and the projection end time of the projection schedule. Determine whether.

  If it is determined in step S2601 in FIG. 26 that the program is being executed (Yes in step SS2601), the process waits until the current time passes the projection end time. On the other hand, if it is determined in step S2601 that it is not being executed (No in step S2601), the process proceeds to step S2602.

  In step S2602, the schedule management unit 2101 deletes the designated projection schedule ("schedule_C103") from the schedule information of the schedule information management unit 377, and then returns to step S2301 in FIG. In this way, by deleting the projection schedule on the condition that the projection schedule is not being executed, malfunction of the signage control process can be avoided.

  FIG. 27B shows a projection schedule screen 2400 after the schedule deletion process of FIG. 26 is executed and the designated projection schedule is deleted. As shown in FIG. 27B, the file name = “Schedule_C103” is deleted from the projection schedule list 2402 on the projection schedule screen 2400.

(5) Details of Content Deletion Processing Next, details of the content deletion processing (step S2313) will be described using FIG. 28 with reference to FIG. FIG. 28 is a flowchart showing the flow of content deletion processing.

  In step S2801 of FIG. 28, the schedule management unit 2101 searches the content stored in the image information management unit 376 for content that is not specified as the content to be projected in the projection schedule. Here, it is assumed that “content 100” to “content 105” are already stored in the image information management unit 376 (see FIG. 6).

  As shown in FIG. 7, “content 100” is designated as the content to be projected in each projection schedule of the schedule information 710 to 730. Further, “content 101” is designated as the content to be projected in the projection schedule of the schedule information 720. Further, “content 102” is designated as the content to be projected in the projection schedule of the schedule information 730.

  On the other hand, “content 103” to “content 105” are not designated as projection-scheduled contents in any of the projection schedules of the schedule information 710 to 730. Therefore, the schedule management unit 2101 obtains content names = “content 103” to “content 105” as content names of unused content.

  In step S2802, the schedule management unit 2101 displays an unused content list screen so that the content name of the unused content obtained in step S2801 can be selected.

  FIG. 29 is a diagram illustrating an example of a projection schedule screen and an unused content list screen. When the unused content list button 2901 is pressed on the projection schedule screen 2400 shown in FIG. 29A, the schedule management unit 2101 displays the unused content list screen on the display unit 405.

  As illustrated in FIG. 29B, the unused content list screen 2900 includes an unused content list 2902. The example of FIG. 29B shows a state in which content names = “content 103”, “content 104”, and “content 105” are displayed as unused content.

  The unused content list screen 2900 includes a delete button 2903 and a return button 2904. The operator 1000 selects a content name of any of the unused contents displayed in the unused content list 2902 and presses a delete button 2903, thereby inputting an instruction to delete the content. . When the return button 2904 is pressed, the schedule management unit 2101 determines that no deletion instruction has been input, and returns to the projection schedule screen 2400 in FIG.

  In step S2803, the schedule management unit 2101 determines whether the content name of the content has been selected by the operator 1000 and a deletion instruction has been input. If the return button 2904 is pressed, it is determined in step S2803 that no deletion instruction has been input (No in step S2803), and the process returns to step S2301 in FIG.

  On the other hand, when the content name of any content is selected and the delete button 2903 is pressed, in step S2803, an instruction to delete the content with the selected content name is input (Yes in step S2803). judge. In this case, the schedule management unit 2101 proceeds to step S2804.

  In step S2804, the schedule management unit 2101 identifies a projection moving image group based on the selected content name, and issues a deletion instruction for each projection moving image included in the identified projection moving image group. To 310_30b.

  Accordingly, the projectors 310_1a to 310_30b delete the projection moving images instructed to be deleted from the connected external memories 320_1a to 320_30b. When the deletion of the projection moving image is completed, the projectors 310_1a to 310_30b notify the information processing device 370 that the deletion of the projection moving image is completed.

  In step S2805, the schedule management unit 2101 determines whether a notification indicating that the deletion of the projection moving image has been received is received from the projectors 310_1a to 310_30b.

  If it is determined in step S2805 that the notification indicating that the deletion of the moving image for projection has been completed is not received (No in step S2805), the process returns to step S2301 in FIG.

  On the other hand, if it is determined in step S2805 that the notification indicating that the deletion of the moving image for projection has been completed (Yes in step S2805), the process proceeds to step S2806.

  In step S <b> 2806, the schedule management unit 2101 deletes the information regarding each projection moving image instructed to be deleted from the image information 600.

  In step S <b> 2807, the schedule management unit 2101 deletes each divided still image group generated when the deletion-instructed moving image is generated from the image information management unit 376.

  As described above, the schedule management unit 2101 does not display (hide) the content name of the content specified as the content scheduled for projection in the projection schedule on the unused content list screen 2900. Thus, even when the operator 1000 accidentally presses the delete button 2903 on the unused content list screen 2900, it is possible to avoid a situation in which the content to be projected is deleted.

  On the other hand, when the operator 1000 selects the content name of the displayed content and presses the delete button 2903 on the unused content list screen 2900, the schedule management unit 2101 uses the projection content specified by the selected content. Delete a video group. That is, the operator 1000 can delete the projection moving image from the external memories 320_1a to 320_30b without performing an operation of transmitting a deletion instruction to each of the projectors 310_1a to 310_30b. As a result, even if the number of projection moving images to be generated is enormous, each projection moving image can be deleted with a simple operation.

<10. Summary>
As is clear from the above description, in the image projection system 300 according to the present embodiment,
-Reverse the moving image provided by the advertiser. Further, based on the position and size of a plurality of window glasses included in a predetermined area on the outer surface of the building, a still image of each frame extracted from the inverted moving image is divided, and a plurality of still images are divided from each still image. A divided still image is generated.
