[0011] (A. Embodiment) FIG. 1 is a block diagram showing a configuration of a communication system 1 according to an embodiment of the present disclosure. As shown in FIG. 1, the communication system 1 includes a terminal 10A owned by a user U and a management device 20. In addition to the terminal 10A, the user U also owns terminals 10B and 10C. The terminals 10B and 10C are included in the communication system 1. As shown in FIG. 1, the terminals 10A, 10B, and 10C and the management device 20 are connected to a communication network NW. The communication network NW is, for example, the Internet. In this embodiment, a case will be described in which the user U owns the terminals 10A, 10B, and 10C; however, any one, any two, or all of the terminals 10A, 10B, and 10C may be loaned to the user U by his or her workplace or the like.

[0012] Terminal 10A, terminal 10B, and terminal 10C are all information processing devices equipped with a communication function for performing data communication via a communication network NW and a program execution function. Terminal 10A is, for example, a smartphone, terminal 10B is, for example, a B5-sized tablet terminal, and terminal 10C is, for example, an A4-sized tablet terminal. Terminals 10A, 10B, and 10C each have liquid crystal panels with different display area sizes, and the pixel densities (hereinafter, "resolutions") of the liquid crystal panels are also different from one another. Therefore, for example, when characters with a 24-point font size are displayed on terminals 10A, 10B, and 10C, the apparent sizes of the characters displayed on terminals 10A, 10B, and 10C are different from one another. The relationship between the apparent size [pixels] of the displayed characters and the font size [points] of the characters is expressed by the following formula (1): Apparent size of characters [pixels] = Font size of characters [points] × Resolution (dpi) × 1 / 72 (1)

[0013] In this embodiment, the resolution of the liquid crystal panel of terminal 10A is 72 dpi, the resolution of the liquid crystal panel of terminal 10B is 96 dpi, and the resolution of the liquid crystal panel of terminal 10C is 300 dpi. In this case, for a character with a font size of 24 points, the apparent size on terminal 10A is 24 pixels, the apparent size on terminal 10B is 36 pixels, and the apparent size on terminal 10C is 100 pixels.

[0014] As shown in FIG. 1, terminal 10A, terminal 10B, and terminal 10 each have program PR1 pre-installed. Program PR1 is a program that allows user U of terminal 10 to view electronic magazines distributed from management device 20 via communication network NW. Program PR1 is an example of an electronic magazine program in the present disclosure. Hereinafter, when there is no need to distinguish between terminal 10A, terminal 10B, and terminal 10C, terminal 10A, terminal 10B, and terminal 10C will be referred to as "terminal 10."

[0015] The management device 20 stores electronic magazine information. The electronic magazine information includes article information about multiple articles (e.g., multiple image data representing images of each article) and font size information in which the font size of the characters describing each article is recorded for each article. The font size information is an example of first information in the present disclosure. The management device 20 also stores a management table TBL1. FIG. 2 is a diagram showing an example of the storage contents of the management table TBL1. As shown in FIG. 2, the management table TBL1 stores, in association with a user ID that is identification information uniquely identifying a user, a registered device ID that is identification information uniquely identifying a terminal owned by the user, size information indicating the best size set by the user for the terminal identified by the registered device ID, and date and time information indicating the date and time the size information was set. The best size refers to the apparent size of characters that the user finds easy to read. The size information is an example of second information in the present disclosure.

[0016] In the example shown in FIG. 2, the user ID of user U is "UID1." The registered device ID of terminal 10A is "D0A," the registered device ID of terminal 10B is "D0B," and the registered device ID of terminal 10C is "D0C." In the example shown in FIG. 2, the size information for terminal 10A is NULL, and the date and time information is also NULL. The fact that the size information and the date and time information are NULL means that the apparent size of the characters to be displayed has not been set. FIG. 2 also shows that for terminal 10B, the apparent size of the characters to be displayed was set to 64 pixels on October 1, 2024, and that for terminal 10C, the apparent size of the characters to be displayed was set to 100 pixels on October 2, 2024. Terminal 10A is an example of a first terminal in the present disclosure. Terminal 10B is an example of a second terminal in the present disclosure, and terminal 10C is an example of a third terminal in the present disclosure. Note that the user U may use a terminal other than the terminal 10A, the terminal 10B, and the terminal 10C, and the other terminal is also an example of the third terminal in the present disclosure. Below, a description will be given of adjusting the size of characters displayed on the terminal 10A and setting the best size for the terminal 10A.

[0017] Fig. 3 is a block diagram showing an example of the configuration of terminal 10A. As shown in Fig. 3, terminal 10A includes a communication device 110, a storage device 120, a processing device 130, a display device 140, an input device 150, a timing device 170, and a bus 180 that interconnects these devices. Note that the configurations of terminals 10B and 10C are similar to that of terminal 10A.

[0018] The communication device 110 includes, for example, a wireless communication circuit. The communication device 110 communicates with other devices wirelessly via a communication network NW. A specific example of the other devices that communicate with the communication device 110 is the management device 20.

[0019] The display device 140 includes a liquid crystal display and a drive circuit for the liquid crystal display. The display device 140 displays various images under the control of the processing device 130. The input device 150 is, for example, a transparent touch sensor that covers the display area of ​​the display device 140. In this embodiment, the display device 140 and the input device 150 form a touch panel. The input device 150 detects a touch operation by a user. The input device 150 provides operation content data representing the detected operation content to the processing device 130. By exchanging this operation content data, the user's operation performed on the input device 150 is transmitted to the processing device 130. The input device 150 may include an operator such as a numeric keypad, or may also include a pointing device such as a mouse.

[0020] The timekeeping device 170 includes, for example, a real-time clock. In response to a request from the processing device 130, the timekeeping device 170 outputs current date and time information indicating the current date and time to the processing device 130.

[0021] The storage device 120 is a recording medium readable by the processing device 130. The storage device 120 includes, for example, a nonvolatile memory and a volatile memory. The nonvolatile memory is, for example, a ROM (Read Only Memory), an EPROM (Erasable Programmable Read Only Memory), and an EEPROM (Electrically Erasable Programmable Read Only Memory). The volatile memory is, for example, a RAM (Random Access Memory). The storage device 120 stores the program PR1.

[0022] The processing device 130 includes one or more central processing units (CPUs). The one or more CPUs are an example of one or more processors. Each of the processor and the CPU is an example of a computer. The processing device 130 reads the program PR1 from the storage device 120 when an instruction to execute the program PR1 is received through an operation on the input device 150. The processing device 130 then executes the program PR1 read from the storage device 120. The processing device 130 operating in accordance with the program PR1 functions as a first acquisition unit 130a, a second acquisition unit 130b, an identification unit 130c, an adjustment unit 130d, a determination unit 130e, and a transmission unit 130f. The functions of the first acquisition unit 130a, the second acquisition unit 130b, the identification unit 130c, the adjustment unit 130d, the determination unit 130e, and the transmission unit 130f of the processing device 130 are as follows:

[0023] First acquisition unit 130a acquires electronic magazine information from management device 20 by communicating with management device 20 using communication device 110. Acquisition of electronic magazine information from management device 20 is performed, for example, when program PR1 is started. Furthermore, processing device 130 operating in accordance with program PR1 displays UI screen G1 including articles from the electronic magazine, as shown in Fig. 4, in accordance with the electronic magazine information acquired from management device 20. UI screen G1 shown in Fig. 4 includes article A1 written in 16-point font and article A2 written in 8-point font.

[0024] The second acquisition unit 130b communicates with the management device 20 using the communication device 110 to acquire best size information managed by the management device 20 in association with the user U. More specifically, if the management device 20 manages the registered device ID of the terminal 10A in association with its size information, the second acquisition unit 130b acquires the size information corresponding to the terminal 10A. On the other hand, if the management device 20 does not manage the registered device ID of the terminal 10A in association with its best size information, the second acquisition unit 130b acquires the size information corresponding to the terminal 10B or the terminal 10C. More specifically, the second acquisition unit 130b acquires the best size information associated with the date and time information indicating the date and time closest to the current date and time, out of the size information corresponding to the terminal 10B and the best size information corresponding to the terminal 10C. For example, if the current date and time is October 3, 2024, the management device 20 does not manage the registered device ID of the terminal 10A in association with its size information, as shown in FIG. 2 . Therefore, the second acquisition unit 130b acquires size information corresponding to the terminal 10B or the terminal 10C. As shown in Fig. 2, the date and time information associated with the terminal 10B represents October 1, 2024, and the date and time information associated with the terminal 10C represents October 2, 2024. Because the date and time information associated with the terminal 10C represents a date and time closer to the current date and time, the second acquisition unit 130b acquires size information (100 pixels) corresponding to the terminal 10C.

[0025] When the identification unit 130c receives a first operation (e.g., a double-tap operation) from a user specifying a location within the article image while an image (hereinafter, an article image) showing at least one of a plurality of articles is displayed on the display device 140 in accordance with article information included in the electronic magazine information, the identification unit 130c identifies the font size of the characters describing the article (hereinafter, the first article) displayed at the location specified by the first operation, based on the font size information included in the electronic magazine information. Specifically, the identification unit 130c first identifies the XY coordinates of the location where the first operation was performed (the location where the double-tap was performed) in the display area of ​​the display device 140. Next, the identification unit 130c determines to which article the location where the double-tap was performed belongs, based on the XY coordinates and the display state of the article taking into account scrolling, etc. Then, the identification unit 130c identifies the font size of the characters describing the first article by referring to the font size information for the relevant article. For example, assume that the first operation is performed on article A2 on the UI screen G1 shown in FIG. 4. In this case, the specifying unit 130c specifies the font size of the characters describing the first article as 8 points.

[0026] Furthermore, when the identification unit 130c receives a second operation (e.g., a long press) from the user that specifies a location within the article image and that is different from the first operation while the article image is being displayed on the display device 140, the identification unit 130c identifies the font size of the characters describing the article (hereinafter, the second article) displayed at the location specified by the second operation, based on the font size information included in the electronic magazine information, in the same manner as the identification of the font size for the first article. For example, suppose that the second operation is performed on article A1 on the UI screen G1 shown in FIG. 4. In this case, the identification unit 130c identifies the font size of the characters describing the second article as 16 points.

[0027] The adjustment unit 130d adjusts the size of the article image to be displayed on the display device 140 based on the font size identified by the identification unit 130c, the size information acquired by the second acquisition unit 130b, and resolution information indicating the pixel density of the display device 140. The resolution information is an example of third information in the present disclosure. More specifically, the adjustment unit 130d calculates the actual size of the characters to be 8 pixels according to formula (1) based on the font size (8 points) of the article corresponding to the location specified in response to the first operation and the resolution information (72 dpi) related to the display device 140 of the terminal. Next, the adjustment unit 130d adjusts the apparent size of the characters displayed on the display device 140 by adjusting the display size of the article using a magnification of 100 pixels (100 / 8=12.5) obtained by dividing the character size (100 pixels) represented by the size information acquired by the second acquisition unit 130b by the actual size. 5, a UI screen G2 including an image of article A2 enlarged 12.5 times is displayed on the display device 140. In this way, according to this embodiment, even if a best size has not been set for terminal 10A, the apparent size of the characters displayed on terminal 10A can be adjusted by using a best size that has been set for another terminal owned by user U.

[0028] The determination unit 130e determines the apparent size set by the user U for the characters to be displayed on the display device 140 of the terminal 10A according to formula (1), based on the font size and resolution information identified by the identification unit 130c based on the second operation. Assume that the second operation is performed on article A1 on the UI screen G1 shown in Fig. 4. That is, if the second article is article A1, the determination unit 130e determines the display character size for the terminal 10A to be 16 x 72 x 1 / 72 = 16 pixels.

[0029] The transmitting unit 130f instructs the management device 20 to manage the size information corresponding to the terminal 10A by transmitting a message including size information indicating the size determined by the determining unit 130e, the registered device ID of the terminal 10A, and the user ID of the user U to the management device 20 using the communication device 110. The management device 20 updates the contents stored in the management table TBL1 in response to the message. As described above, since the current date and time in this embodiment is October 2, 2024, the contents stored in the management table TBL1 are updated as shown in FIG.

[0030] 6 is a flowchart showing the flow of a process for changing the apparent size of displayed characters, among the processes executed by the processing device 130 according to the program PR1. In the first identification process SA110, the processing device 130 functions as an identification unit 130c. In the first identification process SA110, the processing device 130 identifies the font size of the article corresponding to the part specified by the user U through the first operation, based on the font size information.

[0031] In adjustment processing SA120 subsequent to first identification processing SA110, processing device 130 functions as adjustment unit 130d. In adjustment processing SA120, processing device 130 calculates the actual size of the characters according to formula (1) based on the font size of the article corresponding to the portion specified in response to the first operation and resolution information related to the display device of its own terminal, and adjusts the display size of the first article using (best size) / (actual size of the characters) as a scaling factor, thereby adjusting the apparent size of the characters displayed on display device 140.

[0032] 7 is a flowchart showing the flow of the process for setting the apparent size of characters, which is one of the processes executed by the processing device 130 according to the program PR1. In the second identification process SB110, the processing device 130 functions as an identification unit 130c. In the second identification process SB110, the processing device 130 identifies the font size of the article corresponding to the part specified by the user U through the second operation, based on the font size information.

[0033] In a determination process SB120 subsequent to the second identification process SB110, the processing device 130 functions as a determination unit 130e. In the determination process SB120, the processing device 130 determines the apparent size set by the user U for the characters to be displayed on the display device 140 of the terminal 10A, in accordance with formula (1), based on the font size and resolution information of the article corresponding to the portion specified in response to the second operation.

[0034] In transmission processing SB130 subsequent to determination processing SB120, processing device 130 functions as transmission unit 130f. In transmission processing SB130, processing device 130 instructs management device 20 to manage size information corresponding to terminal 10A by transmitting a message including size information indicating the size determined in determination processing SB120, the registered device ID of terminal 10A, and the user ID of user U to management device 20 using communication device 110. Management device 20 updates the stored contents of management table TBL1 in response to the message.

[0035] As described above, according to this embodiment, by performing a first operation of specifying a location within an article image, the apparent size of the characters included in an article of an electronic magazine displayed on the display device can be adjusted to a size set by the user U, eliminating the need to perform time-consuming operations such as pinch-out operations to adjust the apparent size of the characters. In addition, according to this embodiment, by performing a second operation of specifying a location within the article image, the best size for the terminal can be determined.
