These portable terminals are, for example, smartphones, and each include a display surface (101, 201, 301, and 401) and a casing (102, 202, 302, and 402). Further, these portable terminals function as display devices that display images on the display surfaces of the respective mobile terminals. Both the display surface and the casing described above have a rectangular shape. Each display surface has different dimensions. For example, the display surface 101 has a vertical dimension (direction along the long side of the rectangle) of 6 cm and a horizontal direction (direction along the short side of the rectangle) of 4 cm. is there. The display surfaces 201, 301, and 401 have vertical dimensions of 7 cm, 8 cm, and 9 cm, respectively, and horizontal dimensions of 5 cm, 6 cm, and 7 cm. The display system 1 displays a large image that does not fit on each display surface by causing the regions formed on the entire display surfaces to function as one display surface by arranging these portable terminals. Hereinafter, this area is referred to as a “display area”.

  FIG. 2 is a diagram illustrating an appearance when an image is displayed on the display surface of each mobile terminal. In the following figures, the direction indicated by the arrow A1 in the figure is the upper side, and the opposite is the lower side. The direction indicated by the arrow A2 is the right side, and the opposite is the left side. The direction along the arrow A1 is referred to as the up-down direction, and the direction along the arrow A2 is referred to as the left-right direction. These portable terminals are arranged with their respective casings in contact with adjacent portable terminals. In FIG. 2, each mobile terminal has its vertical direction oriented in the vertical direction. The mobile terminal 20 is arranged on the right side of the mobile terminal 10, and the mobile terminal 40 is arranged on the lower side of the mobile terminal 10. Further, the mobile terminals 30 are arranged below the mobile terminal 20 and on the right side of the mobile terminal 40. Further, the mobile terminals are arranged so that the lower left corner of the mobile terminal 20, the upper left corner of the mobile terminal 30, and the upper right corner of the mobile terminal 40 are positioned at the lower right corner of the mobile terminal 10. It has been.

  The display surfaces 101, 201, 301, and 401 of each portable terminal form a display area 501 as a whole. In the display area 501, a fixed image G1 having a predetermined shape is displayed. In the present embodiment, the predetermined shape is a rectangle in which the ratio of the length of the long side to the short side is 4 to 3. The fixed image G1 is divided and displayed on each display surface. In other words, divided images F1, F2, F3, and F4, which are images obtained by dividing the regular image G1, are displayed on the display surfaces 101, 201, 301, and 401, respectively. The fixed image G1 is displayed by these portable terminals by using the portable terminal 10 as a master unit and passing data indicating the divided images F2, F3, and F4 to other portable terminals that are slave units. As described above, the mobile terminal 10 has a function as a base unit that generates and transmits data indicating each divided image displayed by the slave unit from the data indicating the standard image G1, and the mobile terminals 20 and 30 and 40 has a function as a slave unit that displays a divided image indicated by the data transmitted from the mobile terminal 10.

Hereinafter, the hardware configuration of the mobile terminal 10 will be described.
FIG. 3 is a diagram illustrating a hardware configuration of the mobile terminal 10. The mobile terminal 10 includes a control unit 110, a storage unit 120, a touch screen unit 130, a voice input / output unit 140, a first communication unit 150, a second communication unit 160, and a third communication unit 170. It is a computer. The control unit 110 includes an arithmetic device such as a CPU (Central Processing Unit) and a storage device such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The CPU controls the operation of each unit of the mobile terminal 10 by executing a program stored in the ROM or the storage unit 120 using the RAM as a work area. The storage unit 120 is a storage unit such as a hard disk, and stores data and programs used by the control unit 110 for control. In addition, the storage unit 120 stores a program for causing the mobile terminal 10 to realize the above-described function as a parent device. In addition, the storage unit 120 stores data indicating the product name of the terminal (referred to as “aaa” for the sake of simplicity).

  The touch screen unit 130 is a unit that displays an image and receives a user operation, and includes a display unit 131 and a touch sensor 132. The display unit 131 is a liquid crystal display, for example, and has the display surface 101 shown in FIG. The display unit 131 is a display unit that displays an image on the display surface 101. The touch sensor 132 is substantially the same size and shape as the display surface 101, and is provided so as to overlap the display surface 101. The touch sensor 132 is, for example, a capacitance type sensor that detects the position indicated by the indicator using electrostatic coupling with the indicator indicating the display surface. The touch sensor 132 supplies data indicating the detected position to the control unit 110. When an operation image is displayed on the display surface, the user performs an operation by pointing to the image. In this case, the touch sensor 132 supplies operation data corresponding to the image including the detected position, that is, operation data corresponding to the received operation to the control unit 110.

  The voice input / output unit 140 includes a speaker, a microphone, a voice processing circuit, and the like, and inputs and outputs voice related to a call. The first communication unit 150 includes an antenna, a communication circuit, and the like, and performs wireless communication with a communication network (not shown). Thereby, the first communication unit 150 communicates with other mobile terminals via the communication network described above to exchange data indicating voice, electronic mail, etc., or communicates with a Web server, for example, to transmit a character string, an image, Exchanging data indicating video. The second communication unit 160 includes an antenna, a communication circuit, and the like, and performs communication according to the Bluetooth (registered trademark) standard. This Bluetooth communication is performed when the distance between the second communication unit 160 and the communication partner is within a certain range (in this example, within 10 m). When the user performs a predetermined operation on the touch screen unit 130, the second communication unit 160 switches between a state in which communication by Bluetooth is performed and a state in which communication is not performed. Since the third communication unit 170 is not used in the present embodiment, it is indicated by a broken line in FIG. 3 and will be described later.

  The mobile terminals 20, 30 and 40 are computers having a hardware configuration common to the mobile terminal 10 described above, but realize a function as a slave instead of a program for realizing the function as the master. Is different in that a program for storing is stored in each storage unit. In addition, as shown in FIG. 1, each of these portable terminals has different display surface dimensions, and data indicating product names stored in the respective storage units is different. The product names of the portable terminals 20, 30 and 40 are “bbb”, “ccc” and “ddd”, respectively, for the sake of simplicity. Further, in the following, for each unit included in the mobile terminals 20, 30 and 40, “1” at the beginning of the reference numerals of the respective units included in the mobile terminal 10 is changed to “2”, “3” and “4”, respectively. Show. For example, the mobile terminal 20 includes a control unit 210, and the mobile terminal 30 includes a control unit 310.

Next, an operation performed by each mobile terminal in the display process in which the display system 1 displays an image in the display area described above will be described.
FIG. 4 is a sequence chart illustrating an example of a display processing procedure. This display process is performed when the mobile terminals 10, 20, 30, and 40 are all in a state of performing communication by Bluetooth and the distance between them is within the above-described range (10 m). In this example, in the mobile terminal 10, the display process is started when operation data indicating the start of the display process is supplied from the touch screen unit 130 operated by the user to the control unit 110.

  First, the mobile terminal 10 transmits data requesting the mobile terminals 20, 30 and 40 to notify the product name of each mobile terminal (steps S11, S12 and S13). When each of the mobile terminals 20, 30 and 40 receives this data transmitted from the mobile terminal 10, it transmits data indicating the product name of the mobile terminal 10 to the mobile terminal 10 (steps S14, S15 and S16). As a result, the mobile terminals 20, 30 and 40 notify the mobile terminal 10 of the product names of their own terminals (in this example, “bbb”, “ccc” and “ddd”).

  Subsequently, based on the product name indicated by the data transmitted from each mobile terminal, the mobile terminal 10 performs a process of acquiring dimensional information indicating the dimensions of the display surface included in each mobile terminal (step S17). In performing this process, the mobile terminal 10 stores in advance a table in which the product names of various mobile terminals are associated with the dimensions of the display surface included in the mobile terminals in the storage unit 120.

  FIG. 5 is a diagram illustrating an example of a table stored in the storage unit 120. In this table, “product name” “aaa”, “bbb”, “ccc” and “ddd”, and “4 × 6”, “5 × 7”, “6 × 8” and “7 × 9”. “Display surface dimensions” are associated with each other. In this “dimension of the display surface”, the horizontal dimension and the vertical dimension of the display surface are shown in units of cm (centimeter). For example, in this table, the dimensions of the display surface of the mobile terminal whose “product name” is “bbb” are 5 cm in the horizontal direction and 7 cm in the vertical direction. For example, the portable terminal 10 sets the size of the display surface “5 × 7” associated with this table to “bbb” which is the product name indicated by the data transmitted in step S14, as shown in FIG. Obtained as dimension information indicating the dimension of the display surface 201 of the terminal 20. Similarly, the mobile terminal 10 acquires dimensional information indicating the dimensions of the display surface 301 of the mobile terminal 30 and the display surface 401 of the mobile terminal 40. In addition, the mobile terminal 10 sets the size of the display surface “4 × 6” associated with “aaa”, which is the product name of the self terminal indicated by the data stored in the storage unit 120, in the table. It is acquired as dimension information indicating the dimension of the display surface 101 of the terminal.

Next, the portable terminal 10 performs a process of calculating two ratios described below using the dimension information acquired in step S17 (step S18).
FIG. 6 is a diagram for explaining the processing in step S18. In FIG. 6A, assuming that the display area 501 shown in FIG. 2 has no housing of each mobile terminal, the display surfaces (101, 201, 301, and 401) are connected to each other. A virtual display area 501x which is a rearranged virtual area is shown. In FIG. 6A, the boundary of the virtual display area 501x is indicated by a solid line, and the boundary of each display surface is indicated by a broken line.

  6B, an image having the same shape as the fixed image G1 shown in FIG. 2, that is, a fixed image G0 that is a rectangular image in which the ratio of the length of the long side to the short side is 4 to 3. Is shown. In FIG. 6B, the length of the long side is represented as “4 × s” and the length of the short side is represented as “3 × s” in order to represent the ratio of the long side to the short side of the standard image G0. ing. The fixed image G0 is an image virtually displayed on the virtual display area 501x by the mobile terminal 10. The mobile terminal 10 displays the standard image G0 with the direction along the long side in the up-down direction and the direction along the short side in the left-right direction. In the following drawings, the fixed images G0 with different numbers at the end (for example, the fixed image G2) are images having the same shape as the fixed image G0 (that is, images having the same shape as the fixed image G1). Indicates.

  FIG. 6C shows an example of a state in which the standard image G0 is virtually displayed in the virtual display area 501x. FIG. 6C shows both the part displayed in the virtual display area 501x and the part not displayed in the standard image G, and the displayed part is hatched. The hatched portion is also a portion where the fixed image G is displayed in the virtual display area 501x. Hereinafter, this portion is referred to as “image display area 502x”. The area of the image display area 502x varies depending on how the standard image G is displayed in the virtual display area 501x. FIG. 6D shows a state where the standard image G is displayed in the virtual display area 501x so that the area of the image display area 502x is maximized. For example, in this state, the area of the image display region 502x is larger than that in the state shown in FIG.

  The portable terminal 10 calculates the area of the virtual display area 501x using the dimension information acquired in step S17. Further, the mobile terminal 10 calculates the area of the fixed image G0 from the dimensions of the fixed image G0 determined when the fixed image G0 is virtually displayed. Further, the mobile terminal 10 calculates the area of the image display area 502x using these dimension information and dimensions. For example, if the mobile terminal 10 is a case where the fixed image G0 is virtually displayed as shown in FIG. 6C, for example, the mobile terminal 10 divides the image display area 502x into a plurality of rectangles, and the areas thereof are respectively determined. The calculated and summed value is calculated as the area of the image display area 502x.

  The mobile terminal 10 calculates the above-described two ratios using the areas of the virtual display area 501x, the fixed image G1, and the image display area 502x calculated as described above. Specifically, the mobile terminal 10 calculates the ratio of the area of the image display area 502x to the area of the virtual display area 501x as the first ratio. The first ratio is the ratio of the area of the virtual display area 501x where the fixed image G is displayed to the virtual display area 501x, and is hereinafter referred to as “region ratio”. Further, the mobile terminal 10 calculates the ratio of the area of the virtual display region 501x to the area of the standard image G as the second ratio. This second ratio is the ratio of the area of the virtual display area 501x where the fixed image G is displayed to the fixed image G, and is hereinafter referred to as “image ratio”.

The portable terminal 10 calculates the above-described area ratio and image ratio in a plurality of arrangement methods.
FIG. 7 is a diagram showing how to arrange four display screens. In FIG. 7, for ease of explanation, four display screens having the same size are shown, and symbols A, B, C, and D are shown inside each display screen. Further, in FIG. 7, each display surface is illustrated such that the vertical direction (direction along the long side of the rectangle) of each display surface is directed in the vertical direction.

  FIG. 7A shows an arrangement in which all four display surfaces are arranged so as to be adjacent in the left-right direction. In FIG. 7B, all three display surfaces (A, B, and C) are arranged so as to be adjacent in the left-right direction, and one display surface (D) is arranged so as to be adjacent in the vertical direction. The arrangement is shown. Further, in FIG. 7C, the sets of display surfaces A and B are arranged so as to be adjacent to each other in the left-right direction, the set of display surfaces C and D are arranged so as to be adjacent to each other in the left-right direction. It shows how to arrange each other in the vertical direction. The mobile terminal 10 arranges the display surfaces A, B, C, and D in each of these arrangement methods, and arranges them in an arrangement method that combines all the display surface orientations (vertical direction or horizontal direction). In a plurality of arrangement methods, the area ratio and the image ratio are calculated.

Subsequently, the mobile terminal 10 specifies one of a plurality of arrangement methods for which these ratios are calculated based on the area ratio and the image ratio calculated in Step S18 (Step S19). In a certain arrangement, the area ratio and the image ratio of various values are calculated according to the area of the fixed image, the shape of the virtual display area, and the arrangement of the virtual display area and the fixed image.
FIG. 8 is a diagram for explaining changes in the area ratio and the image ratio when the area of the standard image is changed. 8A, 8B, 8C, and 8D, the fixed images G2, G3, G4, and G5 having different areas are set so that the area of the image display region 502x is maximized. An example of the state displayed in the virtual display area 501x shown in FIG. The fixed images G2, G3, G4, and G5 have a vertical dimension × horizontal dimension (unit: cm) of 10.6 × 8, 12 × 9, 17.3 × 13, and 20 × 15, respectively. ing. 8A and 8B, the entire fixed images G2 and G3 are displayed in the virtual display area 501x, while no fixed image is displayed in a part of the virtual display area 501x. In FIGS. 8C and 8D, the fixed images G4 and G5 are displayed on the entire virtual display area 501x, while some of the fixed images G4 and G5 are displayed on the virtual display area 501x. Absent.

  Since the area of the virtual display area 501x is the sum of the areas of the display surfaces shown in FIG. 1, it is 4 × 6 + 5 × 7 + 6 × 8 + 7 × 9 = 170 (unit is square cm). The areas of the fixed images G2, G3, G4, and G5 are 10.6 × 8 = 84.8, 12 × 9 = 108, 17.3 × 13 = 224.9, and 20 × 15 = 300 ( The unit is square cm). Therefore, the area ratios in FIGS. 8A, 8B, 8C, and 8D are 84.8 ÷ 170 = 0.50, 108 ÷ 170 = 0.64, 170 ÷ 170 = 1. 00 and 170 ÷ 170 = 1.00. In addition, the image ratios in FIGS. 8A, 8B, 8C, and 8D are 84.8 ÷ 84.8 = 1.00, 108 ÷ 108 = 1.00, and 170 ÷ 224. 9 = 0.76 and 170 ÷ 300 = 0.57.

  FIG. 9 is a graph showing the relationship between the area of the standard image, the area ratio, and the image ratio in the example of FIG. In FIG. 9A, the vertical axis indicates the area ratio, the horizontal axis indicates the area of the standard image, and in FIG. 9B, the vertical axis indicates the image ratio, and the horizontal axis indicates the area of the standard image. In FIG. 9A, the relationship between the area ratio and the area of the fixed image in the states of FIGS. 8A, 8B, 8C, and 8D is indicated by points P1, P2, P3, and P4, respectively. Has been. In FIG. 9B, the relationship between the image ratio and the area of the fixed image in the states of FIGS. 8A, 8B, 8C, and 8D is indicated by points P5, P6, P7, and P8, respectively. Has been.

  When the area ratio of the standard image is equal to or larger than the area of the standard image G4 indicated by the point P3 (that is, 224.9), as shown in FIG. 9A, the area ratio is independent of the area of the standard image. 1 As shown in FIGS. 8C and 8D, when the size of the standard image is equal to or larger than the size of the standard image G4 (that is, when the area is 224.9 or more), virtual display is performed. This is because the vertical and horizontal dimensions of the region 501x are equal to or smaller than the same dimension of the standard image. In this case, the entire virtual display area 501x fits in the standard image, and the area ratio is 1 regardless of the size of the standard image.

On the contrary, when the dimension of the standard image is smaller than the dimension of the standard image G4, the horizontal dimension of the standard image is smaller than the horizontal dimension of the virtual display area 501x, and the standard image is displayed in the virtual display area 501x. The part where is not displayed appears. In this case, that is, when the area of the regular image is smaller than the area of the regular image G4 (that is, 224.9), the region ratio is smaller than 1.
Further, when the size of the standard image is smaller than the size of the standard image G3, the entire standard image is displayed in the virtual display area 501x. In this case, that is, when the area of the standard image is smaller than the area of the standard image G3 (that is, 108), the area of the image display region 502x is equal to the area of the standard image, and is proportional to the area of the standard image. The area ratio will become smaller.

When the area of the standard image is equal to or smaller than the area of the standard image G3 indicated by the point P6 (that is, 108), the image ratio is 1 regardless of the area of the standard image as shown in FIG. 9B. Become. As shown in FIGS. 8A and 8B, when the size of the standard image is equal to or smaller than the size of the standard image G3 (that is, when the area is equal to or smaller than 108), This is because both the horizontal and horizontal dimensions are within the virtual display area 501x.
On the contrary, when the size of the standard image becomes larger than the size of the standard image G3, the horizontal size of the standard image does not fit in the virtual display area 501x, and a part of the standard image is not displayed in the virtual display area 501x. It becomes like this. In this case, that is, when the area of the regular image is larger than the area of the regular image G3 (that is, 108), the image ratio is smaller than 1.

  In step S <b> 18, the mobile terminal 10 forms the virtual display area 501 x by arranging the display surfaces in the arrangement shown in FIG. 6A, and the maximum area ratio when the image ratio is 1 (hereinafter “maximum area”). And a maximum value of the image ratio when the area ratio is 1 (hereinafter referred to as “maximum image ratio”). That is, in the example shown in FIG. 9, the mobile terminal 10 displays the area ratio (that is, 0.64) at the point P <b> 2 shown in FIG. 9A and the image ratio at the point P <b> 7 shown in FIG. That is, 0.76) is extracted. And the portable terminal 10 stores the data which matched the information which shows this arrangement | positioning, and the extracted area | region ratio and image ratio in the memory | storage part 120 (RAM may be sufficient). The information indicating the arrangement method is, for example, information obtained by combining a character string “arrangement method” such as “arrangement method 001” and “arrangement method 002” and a number determined for each arrangement method.

  By performing the above extraction, in the arrangement shown in FIG. 6A, a fixed image whose entire area is displayed in the virtual display region 501x (hereinafter referred to as “maximum display image”). The area ratio when it is displayed is extracted. In this arrangement, the standard image G3 is the maximum display image. Further, in this arrangement, when the entire virtual display area 501x displays a fixed image, the area of the portion of the fixed image that is not displayed in the virtual display region 501x (in other words, the missing portion) is The image ratio when the smallest one (hereinafter referred to as “minimum missing image”) is displayed is extracted. In this arrangement, the standard image G4 is the minimum missing image. In other words, the maximum display image is a fixed image having the maximum area ratio when the image ratio is 1, and the minimum missing image is the maximum image ratio when the area ratio is 1. This is a standard image.

  FIG. 10 is a diagram for explaining the maximum display image and the minimum missing image in the arrangement method in which the display surfaces 101, 201, 301, and 401 are arranged in a combination of the order and orientation shown in FIG. In FIG. 10A, the display surfaces are arranged so that the left side of the display surface 101 and the left side of the display surface 301 are located on the same straight line. In FIG. 10B, the display surfaces are arranged so that the right side of the display surface 201 and the right side of the display surface 401 are positioned on the same straight line. 10A and 10B, the outer circumferences of the regular images G3 and G4 shown in FIG. 7 are indicated by two-dot chain lines so as to overlap these display surfaces.

  In both the arrangements shown in FIGS. 10A and 10B, the fixed image G3 is the maximum display image described above. The fixed image G3 has a horizontal dimension that is equal to the sum of the horizontal dimensions of the display surfaces 101 and 201 (that is, 9 cm). In other words, the horizontal dimension of the maximum display image is determined by the sum of the horizontal dimensions of the display surfaces 101 and 201. In any of these arrangements, the fixed image G4 is the above-described minimum missing image. The fixed image G4 has a horizontal dimension that matches the total horizontal dimension of the display surfaces 301 and 401 (ie, 13 cm). In other words, the horizontal dimension of the minimum missing image is determined by the sum of the horizontal dimensions of the display surfaces 301 and 401. The display surfaces are arranged in a combination of the order and orientation shown in FIG. 7C, and the positions of the display surfaces 101 and 201 are between the position shown in FIG. 10A and the position shown in FIG. In some cases, the relationship that the dimensions in the left-right direction of the maximum display image and the minimum missing image are determined by the sum of the dimensions described above remains the same. Accordingly, in this case, the maximum display images are all the standard images G3, and the minimum missing images are all the standard images G4.

  In the arrangement method shown in FIG. 10C, the display surfaces are arranged such that the right side of the display surface 201 is positioned on the right side of the right side of the display surface 401. In this arrangement, the horizontal dimension of the maximum display image (the length indicated by the arrow L1 in the drawing) is shorter than the total of the horizontal dimensions of the display surfaces 101 and 201. For this reason, the area of the maximum display image becomes smaller than that shown in FIGS. 10 (a) and 10 (b). In this arrangement, the dimension of the minimum missing image in the left-right direction (the length indicated by the arrow L2 in the figure) is larger than that shown in FIGS. 10A and 10B, while the virtual display area The area has not changed. That is, the image ratio when the minimum missing image is displayed is smaller than that in the arrangement shown in FIGS. 10 (a) and 10 (b). In other words, the area of the portion that is not displayed in the virtual display area in the minimum missing image is larger than that shown in FIGS. 10 (a) and 10 (b).

  As described above, when the display surfaces 101, 201, 301, and 401 are arranged in a combination of the order and orientation shown in FIG. 7C, how the areas of the maximum display image and the minimum missing image are arranged on each display surface. Even if it is a way to arrange, it is decided in one way. In this case, the mobile terminal 10 extracts the area ratio when the one maximum display image is displayed and the image ratio when the one minimum missing image is displayed. In addition, depending on the combination of the above order and orientation, a plurality of areas of the maximum display image and the minimum missing image may be determined depending on the arrangement of the display surfaces. In that case, the mobile terminal 10 extracts a region ratio when the maximum display image is displayed in each arrangement in which the maximum display images of the plurality of areas are respectively displayed, and the minimum omission of the plurality of areas is performed. In each arrangement in which images are displayed, the image ratio when the minimum missing image is displayed is extracted.

  The mobile terminal 10 selects the largest area ratio extracted as described above, and determines how to arrange the display surfaces forming the virtual display area used in calculating the selected area ratio. Specified as an arrangement. Similarly, the mobile terminal 10 selects the largest one of the extracted image ratios, and determines how to arrange the display surfaces that form the virtual display area used when calculating the selected image ratio. Specified as an arrangement. When there are a plurality of area ratios or image ratios that are the largest, the mobile terminal 10 selects, for example, the first calculated area ratio or image ratio, and specifies the arrangement method as described above based on the selected ratio. To do. By performing the process of step S19 as described above, the mobile terminal 10 has the arrangement method in which the maximum value of the area ratio when the image ratio is 1 and the area ratio is 1 among the plurality of arrangement methods. The arrangement method in which the maximum value of the image ratio at the maximum is specified.

  FIG. 11 is a diagram illustrating an example of the arrangement method specified in step S19. In this example, it is assumed that the mobile terminal 10 specifies the arrangement shown in FIG. 11 for both of the two arrangements. In this arrangement, the display surfaces 101, 201, and 401 are oriented vertically in the vertical direction, and the display surface 301 is oriented vertically in the horizontal direction. A display surface 301 is arranged on the right side of the display surface 101, and a display surface 201 is arranged on the right side of the display surface 401. A display surface 401 and a display surface 201 are arranged below the display surfaces 101 and 301. Further, the display surfaces are arranged so that the left side of the display surface 101 and the left side of the display surface 401 are located on the same straight line. A virtual display area 501y is formed by the display surfaces arranged as described above. In FIG. 11, the maximum display image G6 and the minimum missing image G7 in this arrangement are shown by a two-dot chain line.

  The area of the virtual display area 501y is 170 square cm, which is the same as that of the virtual display area 501x. In this arrangement, the vertical dimension of the maximum display image G6 is 6 + 7 = 13 cm in total as the vertical dimension of the display surfaces 101 and 201, and the horizontal dimension of the minimum missing image G7 is the display surfaces 401 and 201. The total of the left and right dimensions is 7 + 5 = 12 cm. Since the ratio of the vertical and horizontal dimensions of the standard image is 4: 3, the area of the maximum display image G6 is 13 × 13 ÷ 4 × 3 = 16.8, and the area of the minimum missing image G7 is 12 × 12 ÷ 3 × 4 = 192. Therefore, in this arrangement, the above-mentioned maximum area ratio is 126.8 / 170 = 0.75, and the maximum image ratio is 170/192 = 0.89. All of these are larger than the same ratio (the maximum area ratio is 0.64 and the maximum image ratio is 0.76) in the arrangement shown in FIG.

Next, the mobile terminal 10 displays an image indicating the arrangement specified in step S19 on the display surface 101 (step S20).
FIG. 12 is a diagram illustrating an example of an image displayed on the display surface 101 in step S20. The portable terminal 10 displays on the display surface 101 an image H1 in which the character string “how to arrange” and rectangular images corresponding to the sizes of the display surfaces are arranged in the arrangement shown in FIG. In these rectangular images, character strings “aaa”, “bbb”, “ccc”, and “ddd”, which are product names of mobile terminals each having a corresponding display surface, are shown. In this image H1, the orientation of each portable terminal is indicated by the orientation of the character string representing the product name. The mobile terminal 10 also includes an image H2 including a character string “display method”, a character string “A: entire display”, and a character string “B: maximum display” below the image H1. H3 is displayed.

  When either one of the images H2 and H3 is selected by the user's operation, the portable terminal 10 determines to display the standard image in the arrangement method indicated by the image (step S21). When the image H2 is selected, the portable terminal 10 displays a fixed image having the same shape and area as the maximum display image G6 in the arrangement specified in step S19. This fixed image may be anything as long as it is an image displayed on the display surface of the mobile terminal, and is, for example, a photograph, a moving image, an image of an Internet site, or the like. In this example, the mobile terminal 10 determines to display the standard image at a position where the maximum display image G6 shown in FIG. 11 is shown. In addition, when the image H3 is selected, the mobile terminal 10 displays a fixed image having the same shape and area as the minimum missing image G7 in the specified arrangement method. In this example, the mobile terminal 10 determines to display the standard image at a position where the minimum missing image G7 shown in FIG. 11 is shown.

Then, the mobile terminal 10 generates data (referred to as divided image data) indicating a divided image obtained by dividing the fixed image based on the data indicating the fixed image (step S22).
FIG. 13 is a diagram for explaining divided images. FIG. 13A shows a state in which a fixed image G16 having the same shape and area as the maximum display image G6 is displayed in the virtual display area 501y shown in FIG. Of the fixed image G16, the images of the portions displayed on the display surfaces 101, 201, 301, and 401 are the divided images F1, F62, F63, and F64, respectively. In this figure, these divided images are hatched for easy understanding. FIG. 13B shows a state in which a fixed image G17 having the same shape and area as the minimum missing image G7 is displayed in the virtual display area 501y. Of the fixed image G17, the images of the portions displayed on the display surfaces 101, 201, 301, and 401 are the divided images F71, F72, F73, and F74, respectively.

  Next, the portable terminal 10 transmits the divided image data generated in step S22 to the portable terminals that display the divided images indicated by the divided image data (steps S23, S24, and S25). Subsequently, the mobile terminal 10 displays the divided image F61 on the display surface 101 based on the divided image data indicating the divided image (in this case, the divided image F61) displayed by the own device (step S26). When the portable terminals 20, 30 and 40 receive the divided image data transmitted to the self-device, they display the divided images indicated by the data (steps S27, S28 and S29).

  FIG. 14 is a diagram illustrating each mobile terminal displaying a divided image. In FIG. 14, the mobile terminals 10, 20, 30, and 40 are arranged such that each display surface has the arrangement shown in FIG. 11 and the adjacent mobile terminals are in contact with each other's casing. . These display surfaces 101, 201, 301, and 401 form the above-described display region 501 as a whole. In FIG. 14A, the mobile terminals 10, 20, 30 and 40 display the divided images F61, F62, F63 and F64 on their respective display surfaces. Moreover, in FIG.14 (b), the portable terminals 10, 20, 30, and 40 are displaying the divided images F71, F72, F73, and F74 on each display surface. In this way, these portable terminals display the fixed image G16 or the fixed image G17 shown in FIG. 13, that is, one image, on the entire display surface (that is, the display area 501) of each portable terminal.

  As described above, even when the mobile terminal 10 performs each process shown in FIG. 4 and the dimensions of the display surfaces of the plurality of mobile terminals are different from each other, as shown in FIG. A large image (for example, the fixed images G16 and G17) that cannot be displayed on each display surface can be displayed by using each display surface as one display surface in a state where terminals are arranged.

  The larger the size of the image to be displayed in this way, the greater the amount of information transmitted from the image to the user. For example, when a certain sentence is represented in the image, if the image becomes small, the character size of the character included in the sentence becomes small and difficult to see, and the amount of information transmitted to the user decreases. On the other hand, when the image is enlarged, the character size of the character that is difficult to see becomes larger and easier to see, and the amount of information transmitted to the user increases. Also, even if the image represents a photograph of a certain person, if the image becomes small, it becomes difficult to know who the person is and what kind of clothes, and the amount of information transmitted to the user is small. Become. On the other hand, when the image becomes larger, it becomes easier to understand them, and the amount of information transmitted to the user increases.

  When the image H2 shown in FIG. 12 (shown as “A: entire display”) is selected in step S21, the entire fixed image G16 is displayed in the display area 501 as shown in FIG. Will be. For this reason, in the display system 1, it is possible to display the maximum one of the fixed images that can be displayed entirely in the display area 501 without losing the information of the fixed image G16. In other words, it is possible to specify the arrangement of the mobile terminals capable of such display. Thereby, in the display system 1, compared with the case where the arrangement | positioning method is not specified as mentioned above, the amount of information conveyed to a user by a fixed form image can be increased.

  When the image H3 shown in FIG. 12 (shown as “B: maximum display”) is selected in step S21, the standard image G17 is displayed in the entire display area 501 as shown in FIG. 14B. Will be. For this reason, in the display system 1, the size of the fixed image G17 is increased and the area of the fixed image G17 that is not displayed is minimized while the size of the fixed image G17 is increased compared to the case where there is a portion that does not display the fixed image in the display area 501. Thus, it is possible to increase the amount of information transmitted to the user by the fixed image G17. As described above, in the display system 1, when displaying images such as the fixed images G16 and G17 in the virtual display area 501x, pay attention to the amount of information conveyed to the user by the displayed image. The arrangement method can be specified.

The portable terminal 10 realizes the following functions by the control unit 110 executing programs to control each unit.
FIG. 15 is a functional block diagram illustrating functions realized by the mobile terminal 10. The mobile terminal 10 includes a first acquisition unit 101, a calculation unit 102, a specification unit 103, a first display control unit 104, a second display control unit 105, a second acquisition unit 106, a detection unit 107, And a determination unit 108. The first acquisition unit 101 performs the processing from step S11 to step S17 shown in FIG. 4 so that the data indicating the dimensions of the display surface of the terminal itself (that is, the dimension information of the mobile terminal 10) and the other display devices It functions as an acquisition means (first acquisition means) for acquiring data indicating the dimensions of the display surface (that is, each dimension information of the mobile terminals 20, 30 and 40). The first acquisition unit 101 supplies the acquired data to the calculation unit 102.

  The calculation unit 102 performs the process of step S18 illustrated in FIG. 4 to form the entire display surface (display surfaces 101, 201, 301, and 401) by arranging the own terminal and other portable terminals. When a fixed image (for example, the fixed image G1) having a predetermined shape is displayed in a region (for example, the virtual display region 501x shown in FIG. 6), the dimensions indicated by the data acquired by the first acquisition unit 101 and the dimensions of the fixed image Is a calculation means for calculating the above-described area ratio and image ratio. The calculation unit 102 calculates the area ratio and the image ratio for a plurality of arrangement methods (specifically, a plurality of arrangement methods as described in FIGS. 9 and 10) of the own terminal and other portable terminals. The calculation unit 102 supplies data indicating the calculated area ratio and image ratio to the specifying unit 103.

  The specifying unit 103 performs the process of step S19 illustrated in FIG. 4 to identify the arrangement method in which the maximum area ratio is the largest and the arrangement method in which the maximum image ratio is the largest among the plurality of arrangement methods described above. It functions as a specific means. The identification unit 103 performs this identification based on the area ratio and the image ratio calculated by the calculation unit 102. The specifying unit 103 supplies data indicating the specified arrangement method to the first display control unit 104 and the second display control unit 105.

  The first display control unit 104 performs the processing from step S22 to S26 shown in FIG. 4 to display the portion displayed by the terminal in the standard image on the display unit 131, and the other portable image in the standard image. It functions as a first display control means for performing processing for displaying the portion displayed by the terminal on those other portable terminals. The first display control unit 104 performs this process on a fixed image (for example, a display region 501 shown in FIG. 2) formed by arranging its own terminal and another portable terminal in the arrangement method specified by the specifying unit 103. This is performed when the standard image G10) is displayed.

The second display control unit 105 performs the process of step S20 illustrated in FIG. 4 to display an image (for example, the image H1 illustrated in FIG. 12) indicating the arrangement specified by the specifying unit 103 on the display unit 131. 2 It functions as a display control means. Note that the second display control unit 105 may display an image indicating this arrangement on the display unit of another mobile terminal instead of displaying the image on the display unit 131.
Since the second acquisition unit 106, the detection unit 107, and the determination unit 108 are not used in this embodiment, they are indicated by broken lines in FIG. 15 and will be described later.

[Modification]
The above-described embodiment is merely an example of implementation of the present invention, and may be modified as follows. Moreover, you may implement combining embodiment mentioned above and each modification shown below as needed.

(Modification 1)
In the above-described embodiment, the mobile terminal 10 specifies the arrangement method by the method described in step S19 illustrated in FIG. 4, but the arrangement may be obtained by a method different from this. For example, the mobile terminal 10 may specify only one of the two arrangements instead of specifying the two arrangements as in the embodiment. In this case, in step S19, the mobile terminal 10 executes one of these processes instead of performing the two processes specifying the two arrangement methods. In step S <b> 20, the mobile terminal 10 displays the image H <b> 1 indicating the arrangement method specified by any of the processes described above, but does not display the images H <b> 2 and H <b> 3 and the character string “display method”. Then, for example, when this image H1 is selected, the mobile terminal 10 performs a process of displaying the standard image in the arrangement method specified in step S19.

(Modification 2)
In the above-described embodiment, the mobile terminal 10 has an arrangement method in which the maximum value of the area ratio when the image ratio is 1 among the plurality of arrangement methods and the maximum value of the image ratio when the area ratio is 1. Although the arrangement method with the largest is specified, a different arrangement method may be specified. For example, the mobile terminal 10 may specify an arrangement method in which a value obtained by multiplying the above-described maximum area ratio and the maximum image ratio (hereinafter referred to as “ratio multiplication value”) is the largest among a plurality of arrangement methods. For example, in the example shown in FIG. 7, the maximum area ratio is 0.76 indicated by a point P7 in FIG. 8, and the maximum image ratio is 0.64 indicated by a point P2. That is, the mobile terminal 10 calculates 0.76 × 0.64 = 0.49, which is a value obtained by multiplying these values, as a ratio multiplication value. Similarly to this, the mobile terminal 10 calculates the ratio multiplication value for other arrangement methods, and specifies the arrangement method in which the calculated ratio multiplication value is maximized.

  In the present modification, both the maximum value of the image ratio when the area ratio is 1 and the maximum value of the area ratio when the image ratio is 1 are relatively large from among a plurality of arrangement methods. Things will be identified. When arranged in this manner, the area of the maximum display image is relatively large, and the area of the missing portion in the minimum missing image is relatively small. Therefore, as in the above-described embodiment, when the user selects whether to make the shape and area of the fixed image to be displayed the same as the maximum display image or the same as the minimum missing image, according to this modification. For example, regardless of which is selected, the amount of information conveyed to the user by the displayed fixed image can be relatively increased.

(Modification 3)
In the above-described embodiment, the mobile terminal 10 specifies the arrangement method by the method described in step S19, but the arrangement may be obtained by a method different from this. For example, in the embodiment, the mobile terminal 10 specifies the arrangement method in which the maximum value of the area ratio is the largest or the arrangement method in which the maximum value of the image ratio is the largest as described above, but these maximum values are the largest. You may specify how to arrange other than. For example, the mobile terminal 10 has the largest area ratio and image ratio among the arrangement methods for forming the virtual display area used when calculating the area ratio and the image ratio extracted as described above in step S19. Any of the arrangement methods included in the order determined from the thing may be specified. Thereby, the portable terminal 10 specifies the arrangement method in which the image ratio when the area ratio is 1 is a relatively large value from among the plurality of arrangement methods described above, or when the image ratio is 1. For example, it is possible to specify an arrangement method in which the area ratio is a relatively large value.

  Further, the mobile terminal 10 may specify a predetermined number (for example, two or three) of arrangement methods in addition to specifying any one arrangement method. In this case, the mobile terminal 10 displays a plurality of images respectively indicating the plurality of specified arrangement methods in step S20. Then, when the user selects any one of the images, the mobile terminal 10 determines in step S21 that the fixed image is displayed in the arrangement method indicated by the selected image. As a result, the user can select the arrangement method from among a plurality of arrangement methods for displaying the maximum display image or a plurality of arrangement methods for displaying the minimum missing image.

(Modification 4)
The portable terminal 10 may use a combination of the methods described in the first, second, and third modifications when specifying the arrangement in step S19. For example, the mobile terminal 10 may specify three arrangement methods using both the method described in the embodiment and the method described in Modification Example 2, and may cause the user to select one of these arrangement methods. Further, when the mobile terminal 10 specifies these three arrangement methods, the maximum value of the area ratio when the above-described image ratio is 1, the maximum value of the image ratio when the area ratio is 1, and the ratio multiplication value It is also possible to select items included in the order determined from the largest value to the largest value, and to specify the arrangement method for forming the virtual display area used when calculating the selected maximum value.

  When the mobile terminals are arranged in the arrangement method specified by any of the methods described above, the fixed image displayed in the display area formed by each display surface is the maximum area ratio when the image ratio is 1 Is displayed with the largest value or a relatively large value, or when the area ratio is 1, the maximum value of the image ratio is displayed with the largest value or a relatively large value. Become. As a result, if the entire standard image is displayed in the display area, an image with the maximum or relatively large area of the standard image displayed is displayed, and the standard image is displayed in the entire display area. If the image is a fixed image, an image having a minimum or relatively small area of the missing portion is displayed. In any of these cases, the display system 1 can maximize or relatively increase the amount of information transmitted to the user by the displayed fixed image. In short, the mobile terminal 10 may be any device that specifies any arrangement in which the amount of information transmitted to the user through the fixed image satisfies a predetermined condition. The predetermined condition here is satisfied when, for example, the amount of information transmitted to the user can be maximized or relatively large as described above.

(Modification 5)
The portable terminal 10 may specify how to arrange using the dimension of the part used as the frame surrounding a display surface.
FIG. 16 is a diagram showing the configuration of the display system 1a in the present modification. The display system 1a includes mobile terminals 10a and 20a. The portable terminals 10a and 20a have casings 102a and 202a, respectively, and have the same configuration as the portable terminals 10 and 20 except for the dimensions of these casings. In FIG. 16, the mobile terminals 10 a and 20 a have their respective vertical directions (directions along the long side of the display surface) facing up and down. The display surface 101 is surrounded by a frame 103, and the display surface 201 is surrounded by a frame 203. These frames 103 and 203 are formed by casings 102a and 202a, respectively. The frame 103 has a width of 1 cm at each portion in contact with each side of the display surface 101. The frame 203 has a width of 2 cm at a portion in contact with the right side of the display surface 201 and a width at a portion in contact with the other side of 1 cm.

  FIG. 17 is a diagram illustrating an example of a virtual display area formed by the display surfaces 101 and 201 and a standard image displayed in the virtual display area. The mobile terminal 10 virtually displays the standard image G18 in a virtual display area formed by the display surfaces 101 and 201 arranged in the vertical direction with the vertical direction set to the horizontal direction. The fixed image G18 is a fixed image in which the area ratio is maximum when the image ratio is 1. A divided image F81, which is an image obtained by dividing the regular image G18, is displayed on the display surface 101, and a divided image F82, which is an image obtained by dividing the regular image G18, is displayed on the display surface 201.

  FIG. 18 is a diagram illustrating an example of how to arrange mobile terminals that display the divided images F81 and F82, respectively. In FIG. 18, the mobile terminals 10 a and 20 a are arranged with the respective vertical directions directed in the left-right direction. As shown in FIG. 16, the frame 203 of the mobile terminal 20a has different dimensions on the left and right of the display surface 201 (1 cm and 2 cm). For this reason, when the display surfaces 101 and 201 are arranged as shown in FIG. 17, as shown in FIGS. 18A and 18B, either the smaller or larger dimension of the frame 203 between the two display surfaces is selected. The interval between the two display surfaces varies depending on the arrangement. In FIG. 18A, the smaller dimension of the frame 203 is arranged between the display surfaces, and the distance between the display surfaces is 2 cm. In FIG. 18 (b), the larger dimension of the frame 203 is arranged between both display surfaces, and the distance between both display surfaces is 3 cm.

When acquiring the dimension information in step S <b> 17 shown in FIG. 4, the mobile terminal 10 a acquires dimension information indicating the dimensions of the frame in addition to the dimension information indicating the dimensions of the display surface. In performing this process, the mobile terminal 10a stores, in the storage unit 120, a table in which product names of various mobile terminals are associated with display surface and frame dimensions of the mobile terminals. .
FIG. 19 is a diagram illustrating an example of a table stored in the storage unit 120. In this table, “product names” “aaa” and “bbb” are associated with “frame dimensions” “1, 1, 1, 1” and “1, 1, 2, 1”. . In these “frame dimensions”, the dimensions of the portions in contact with the upper, lower, left, and right sides of the display surface are shown in units of cm (centimeter). The mobile terminal 10a, for example, “bbb”, which is the product name indicated by the data transmitted in step S14, and the dimensions of the display surface “5 × 7” associated with this table are “1, 1, 2,”. The dimension of the frame “1” is acquired as dimension information of the mobile terminal 20a. In addition, the mobile terminal 10a has a display surface dimension “4 × 6” associated with “aaa”, which is the product name of the terminal indicated by the data stored in the storage unit 120, and “1”. The size of the frame “1, 1, 1” is acquired as the size information of the terminal itself.

  The portable terminal 10a realizes the function shown in the second acquisition unit 106 indicated by a broken line in FIG. 15 when the control unit 110 executes the program and controls each unit. The second acquisition unit 106 performs the processes from step S11 to step S17 according to this modification, so that data indicating the dimensions of the frame of the terminal (that is, the dimension information of the mobile terminal 10a) and other display devices It functions as an acquisition means (second acquisition means) for acquiring data indicating the dimensions of the frame it has (that is, the dimension information of the mobile terminal 20a). The second acquisition unit 106 supplies these acquired data to the specifying unit 103.

  Next, the calculation unit 102 of the mobile terminal 10a calculates the area ratio and the image ratio using the dimensions of the display surface indicated by the dimension information acquired by the first acquisition unit 101 (step S18), The arrangement method is specified using the frame dimensions indicated by the dimension information acquired by the second acquisition unit 106 (step S19). Specifically, the portable terminal 10a uses the frame dimensions indicated by the data acquired by the second acquisition unit 106 when there are a plurality of arrangements in which the maximum area ratios are equal to each other. The arrangement method with the smaller frame size is specified as the arrangement method satisfying the predetermined condition described in the fourth modification. In addition to the case where the maximum display image with the maximum area ratio is displayed as described above, the mobile terminal 10a uses the dimensions of the frame to display the minimum missing image with the maximum image ratio. You may specify how to arrange as follows. In this case, the portable terminal 10a is located between the display surfaces using the frame dimensions indicated by the data acquired by the second acquisition unit 106 when there are a plurality of arrangements in which the maximum image ratios are equal to each other. The arrangement method with the smaller frame size is specified as the arrangement method satisfying a predetermined condition.

  According to this modification, it is possible to specify an arrangement method in which the gaps between the display surfaces become smaller when the mobile terminals are arranged. The smaller the gap is, the closer each display surface is, and the information represented by the fixed image obtained by combining the divided images displayed on those display surfaces is easily recognized. Therefore, in the display system 1a according to the present modification, it is possible to easily recognize information represented by the standard image.

When the mobile terminal 10 displays the above-described maximum display image, for example, the fixed image G16 as shown in FIG. 14, the other portion of the display area where the fixed image is not displayed (hereinafter referred to as “non-display portion”). An image may be displayed. In the display surface 401 shown in FIG. 14A, the non-display portion is a portion of the display surface 401 excluding the portion where the divided image F64 is displayed. The portable terminal 10 may display a part of an image having an area larger than that of the fixed image originally as the fixed image. For example, an image such as a map or spreadsheet software. In that case, the portable terminal 10 displays the portion outside the fixed image in those images on the non-display portion. Thereby, a non-display part can be utilized effectively.

  In addition, the mobile terminal 10 displays an image that can be selected by the user, such as the selection image H4 indicated by a broken line in FIG. 14A, in the non-display portion, and the selection image H4 is selected by the user. In addition, the above-described minimum missing image, that is, the regular image G17 shown in FIG. 14B may be displayed. Thereby, compared with the case where the selected image H4 is not displayed, the user can easily switch the image to be displayed. In addition, when the plurality of arrangement methods are specified in step S19 as described in the modification example 4, the mobile terminal 10 selects a non-display portion for switching to an arrangement method that has not been selected from the plurality of arrangement methods. An image may be displayed. Thereby, compared with the case where the selected image is not displayed, the user can easily switch to another arrangement method.

(Modification 7)
In the above-described embodiment, the mobile terminal 10 calculates the area ratio and the image ratio using the area of the standard image, the virtual display area, and the image display area. In addition to the area, for example, the pixels of these images and areas These ratios may be calculated using numbers (also referred to as dot numbers). In this case, instead of the table shown in FIG. 5, the mobile terminal 10 stores, in the storage unit 120, the “display surface dimension” in which the number of pixels is used instead of the length. Next, in step S17, the number of pixels in the virtual display area is calculated by obtaining dimensional information using this table. Then, the mobile terminal 10 calculates the number of pixels in the image display area by using, for example, a fixed image in which the ratio of the number of pixels in the vertical direction and the horizontal direction is 4 to 3, and calculates the respective ratios. As described above, in short, the mobile terminal 10 acquires the data (dimension information) indicating the dimensions of the display surface of its own terminal and the dimensions of the display surface of other mobile terminals, and uses the dimensions indicated by the data, The ratio of the size of the image display area to the virtual display area may be calculated as the area ratio, and the ratio of the size of the image display area to the fixed image may be calculated as the image ratio.

The mobile terminal 10 may perform the display process shown in FIG. 4 again when the number of other mobile terminals capable of displaying the divided image changes. When this number has changed, for example, when any of the mobile terminals arranged as shown in FIG. 14 can no longer perform Bluetooth communication, for example, by starting communication via a mobile phone. Or when a new mobile terminal can communicate with the mobile terminal 10 via Bluetooth. In this case, the portable terminal 10 functions as the detection unit 107 indicated by a broken line in FIG. 15 by the control unit 110 executing the program to control each unit. The detection unit 107 performs a process of determining the number of mobile terminals that can perform Bluetooth communication at predetermined time intervals. And the detection part 107 supplies the data which show the number determined by implementing this process to the 1st acquisition part 101 (and 2nd acquisition part 106). In this way, the detection unit 107 functions as a detection unit that detects the number of other mobile terminals that can display images by the first display control unit 104.

  When there is a change in the number detected by the detection unit 107, the first acquisition unit 101 (and the second acquisition unit 106) displays the dimensions of the display surface (and the frame Data indicating the dimension) is acquired. Thereafter, the calculation unit 102 and the specifying unit 103 perform the processing described with reference to FIG. 15, thereby specifying how to arrange the number of portable terminals detected by the detecting unit 107 and the own terminal. According to this modification, when the number of other mobile terminals capable of displaying a divided image changes, the fixed image can be displayed with the changed number.

(Modification 9)
In the embodiment and the modification described above, the mobile terminal acquires the product name from another mobile terminal, and acquires the dimensions of each display surface and the dimensions of each frame using the tables shown in FIGS. These dimensions may be obtained by other procedures. In other procedures, for example, a name that can identify each mobile terminal, such as a model or model name, may be used instead of the product name, and each mobile terminal stores the dimensions of the display surface and the dimensions of the frame in advance. In addition, each portable terminal may notify those dimensions to the portable terminal functioning as the master unit. In short, in a display system, if a portable terminal functioning as a master unit can acquire data indicating the dimensions of the display surface and the dimensions of the frame, the data can be acquired by any procedure. It may be.

(Modification 10)
The mobile terminal 10 may display a fixed image having a different shape depending on the type of content. For example, if the content type is a high definition (HD) image and video, the mobile terminal 10 displays a standard image having a ratio of the length in the vertical direction to the horizontal direction of 9:16. If the content type is a smartphone mail, a fixed image having the above-described ratio (for example, 3 to 2) in the image displayed by the mail program is displayed. That is, in this modification, the shape of the fixed image is determined by the type of content represented by the fixed image. In this case, the portable terminal 10 functions as the determination unit 108 indicated by a broken line in FIG. 15 when the control unit 110 executes the program and controls each unit. The determination unit 108 functions as a determination unit that determines the type of content represented by the standard image.

  The determination unit 108 determines the type of content depending on how the data indicating the standard image to be divided in step S22 shown in FIG. 4 is acquired, for example. For example, the portable terminal 10 stores each program of the terminal itself in the storage unit 120 in association with the content type predetermined for each program. Then, when the mobile terminal 10 displays an image displayed when one of these programs is executed as a standard image, the mobile terminal 10 refers to the storage unit 120 and corresponds to the executed program. Is determined as the type of content represented by the standard image.

  In addition, a moving image and an image file that are sources of data indicating a fixed image may include information indicating the aspect ratio of the moving image and the image. In this case, the determination unit 108 determines the content type corresponding to the aspect ratio (that is, the shape of the standard image) obtained by referring to those files as the type of content represented by the standard image. The determination unit 108 supplies data indicating the determination result (content type) to the calculation unit 102. Thereafter, the calculation unit 102 and the specifying unit 103 perform the processing described with reference to FIG. 15, thereby specifying the arrangement method when displaying the fixed image having a shape corresponding to the type of content determined by the determining unit 108. According to this modification, it is possible to display a fixed image having a shape corresponding to the type of content.

(Modification 11)
The mobile terminal 10 may display any image in the display area 501 as long as the mobile terminal 10 displays the image on the display surface 101. For example, the mobile terminal 10 may receive a broadcast wave transmitted from a broadcast station and display a fixed image indicating a program represented by the broadcast wave. The portable terminal 10 receives a broadcast wave using the third communication unit 170 indicated by a broken line in FIG. The third communication unit 170 has an antenna that receives a broadcast wave and a tuner that is connected to the antenna. The third communication unit 170 receives a broadcast wave transmitted from each broadcast station, and receives program audio, video, and characters from the broadcast wave. Demodulate the data it represents. In step S22 shown in FIG. 4, the portable terminal 10 divides the image represented by the video and characters represented by this data to generate divided image data, and transmits the generated divided image data to each portable terminal. The video and characters are displayed in the display area. In addition, the mobile terminal 10 outputs the sound from the sound input / output unit 140 based on the data representing the demodulated sound. Note that the mobile terminal 10 may transmit data representing voice to another mobile terminal and output the data from the mobile terminal.

(Modification 12)
In the display system 1, each mobile terminal may generate divided image data instead of the mobile terminal 10 serving as a parent device generating divided image data as in the above-described embodiment. In this case, the mobile terminal 10 transmits acquisition source data indicating an acquisition destination of image data indicating a fixed image to be displayed, and region data indicating a region of a portion displayed by each mobile terminal in the fixed image. This acquisition destination data is data indicating a URL (Uniform Resource Locator) of a certain website, for example, when displaying a certain website, and when displaying a certain program as in the above modification example. If so, the data indicates the channel number of the program. Also, the area data is, for example, the upper left coordinates and the lower right coordinates of the area when a coordinate system having two axes in the vertical direction and the horizontal direction with the upper left as the origin is defined in advance. It is data which shows. In this case, the other mobile terminal first acquires image data from the acquisition destination indicated by the acquisition destination data transmitted from the mobile terminal 10. Next, the other portable terminal is a portion surrounded by a rectangle represented by the coordinates indicated by the area data transmitted together with the acquisition destination data in the fixed image indicated by the acquired image data, that is, the own terminal Is displayed on each display surface. In short, the mobile terminal 10 causes the display unit 131 to display a part of the standard image displayed on the display unit 131, and display a part of the standard image displayed on the other mobile terminal on the other mobile terminal. It only has to come to do.
