BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be embodied in many forms and is not limited only to the specific examples described in the embodiments shown below.

FIG. 1 is a diagram showing an outline of a centralized screen display management system (hereinafter referred to as "this system") S according to this embodiment. As shown in the figure, this system S has a centralized control computer 1 and a plurality of information terminals 2 connected to the centralized control computer 1 . The centralized control computer 1 and the plurality of information terminals 2 are connected via an electric communication line N.

In the system S, the recording medium of the centralized control computer 1 includes (1) a step of recording terminal identification data and resolution data for each of the plurality of information terminals 2, and (2) common step of recording the image data; (3) adjusting the resolution of the common image data based on the resolution data of each of the plurality of information terminals 2 to create and record a plurality of adapted common image data adapted to each of the plurality of information terminals 2; and (4) a step of transmitting matching common image data to each information terminal.

In this system S, the image data corresponding to each information terminal is adjusted and recorded on the centralized control computer 1, the so-called server side, and the load on each information terminal can be reduced. In addition, it is possible to link the user and the information terminal on the server, and furthermore, the information written by the user (layer information) can be linked to the user, and if the user uses another information terminal But it can be dealt with. Of course, it is also possible to record the layer information on the server corresponding to the information terminal.

The centralized control computer 1 used to execute this program is not limited as long as it has the above functions. Non-volatile recording media such as flash memory, volatile recording media such as memory, buses connecting these, input devices such as keyboards and mice, and display devices such as monitors. .

The central control computer 1 is preferably a so-called notebook computer or desktop computer from the viewpoint of easy operation, but mobile information terminals that have become popular in recent years, specifically so-called smartphones and tablet terminals may be A general mobile information terminal is one in which components such as the CPU and the display device are housed and integrated in one cover, and a sensor is arranged on the display device to form a so-called touch panel. And it is very easy to handle, which is preferable. Moreover, in the case of a mobile information terminal, a program for executing this method is recorded and displayed as a so-called application on the mobile information terminal, and this method can be easily performed by activating this application.

Further, the information terminal 2 of the system S can employ the same configuration as the centralized control computer 1 described above. However, from the viewpoint of portability and ease of installation, the information terminal 2 is not a notebook computer or desktop computer, but a so-called smart phone, tablet terminal, electronic paper, etc., which is easy to carry and install. is preferably In recent years, price tags and the like using electronic paper have been particularly used in commercial facilities such as so-called supermarkets, and application to these can also be considered. In particular, in the case of a simple information terminal such as a price tag using electronic paper, it is often the case that the resolution and display color of input image data cannot be directly applied to the information terminal. Therefore, appropriate display can be achieved by adjusting in advance on the side of the centralized control computer 1 . If such a system is used, there is no need to install software for image processing on the information terminal side, and there is also the advantage that a simpler and less expensive information terminal can be adopted.

Next, each step executed by the centralized control computer 1 of this system S will be described.

This system S first has a step of (1) recording terminal identification data and resolution data for each of a plurality of information terminals 2 .

Here, "terminal identification data" is data including information used for distinguishing between individual information terminals 2, since a plurality of information terminals 2 are connected in this system S. FIG. Examples of the information used to distinguish the information terminal include model information and serial number of the information terminal, but the information is not limited to this.

"Resolution data" is data that includes information about the resolution that can be displayed by the display device of the information terminal 2. FIG. "Resolution" indicates the number of vertical and horizontal dots in the display device. can be displayed. Resolution data is data that includes information about these numerical values. In this system S, it is assumed that each information terminal has a different resolution, and the centralized control computer 1 varies the image data to be displayed according to this resolution, adjusts the resolution to correspond to each information terminal, and transmits the image data. By doing so, it is possible to perform adjustment processing suitable for the resolution of each information terminal, reduce the load on each information terminal, and achieve a system that enables optimum image display. Note that the resolution data may include data regarding the number of pixels of the display device.

The system S also has a step of (2) recording common image data. Here, "common image data" is data including information of an image (common image) to be commonly displayed on a plurality of information terminals 2 in this system S. FIG. Note that this common image data includes resolution data, and is appropriately modified according to the resolution of each information terminal 2 to create adapted common image data, which will be described later. This common image data is recorded in the recording medium of the central control computer 1 as described above.

In addition, in this system S, (3) based on the resolution data of each of the plurality of information terminals 2, the resolution of the common image data is adjusted, and a plurality of adapted common image data adapted to each of the plurality of information terminals 2 are created and recorded. have the step of As is clear from the above description, the "matching common image data" is a common image obtained by adjusting the resolution data of the common image data so as to match the displayable resolution data of the information terminal 2 to which the image data is to be transmitted. Data. For example, if the resolution of the common image data is 1024×768 and the maximum resolution of the information terminal 2 to which the common image data is to be transmitted is 800×600, the resolution of the common image data is adjusted accordingly. . Note that this compatible common image data may be created by adjusting the common image data as appropriate when the information terminal that transmits this data is set. It is also preferable to create and record data. It should be noted that a known method can be employed for this image data adjustment processing.

In this case, if the common image data includes characters, etc., it is preferable to include the included information, specifically, text information. If the image is enlarged or reduced as it is, especially when characters are included, problems such as blurring of the contours of the characters and crushing of the characters tend to occur. Therefore, by extracting the included characters as text information, it becomes possible to insert characters with different sizes, and the above problems can be reduced. Further, in this case, the text information has a position to be inserted in the common image data, thereby further solving the problem.

In addition, the system S has (4) a step of transmitting suitable common image data to each information terminal. By this step, it becomes possible to transmit the optimum common image data to each information terminal and cause the display device thereof to perform appropriate screen display. FIG. 2 shows an image diagram of the common image data stored in the centralized control computer 1 and the matching common image data displayed on the information terminal with a lower resolution than the common image data.

By the way, in this system S, there are cases where each information terminal is provided with a configuration for creating image data. In some cases, the user himself/herself writes his/her own memo, which is established as another image data. Therefore, the system S preferably has a step of (5) recording individual layer image data corresponding to each piece of terminal identification data. In other words, if you operate the information terminal as described above and add your own memo to the compatible common image data and enter it, the data of this entered part will be separated into individual layer image data (individual layer image data ) and sent to the central control computer 1. As a result, the individual layer information recorded for each information terminal is recorded in the centralized control computer 1, and even if the information terminal is used by a different person, only the compatible common image data will be recorded separately. is displayed and used by the user who created the individual layer image data again, the matching image data can be used efficiently by causing the information terminal to output the individual layer image data. FIG. 3 shows images of common image data and individual layer image data. Of course, in this case, it is preferable to attach tag data corresponding to at least one of the original common image data and the adapted common image data.

In the above steps, the individual layer image data corresponding to the information terminal is recorded. However, there are cases where it is desired to display individual layer image data created in another information terminal on the information terminal being used. Therefore, the system S preferably also includes (6) a step of recording a plurality of user identification data and a step of recording individual layer image data corresponding to each of the user identification data. By doing so, even when the user uses a different information terminal as described above, it is possible to display individual layer image data already created by another information terminal.

As a specific process for executing step (6) above, in the system S, (7-1) correspondence data in which the user identification data and the terminal identification data are associated is recorded, and the terminal associated with the user identification data is There is a step of adjusting the resolution of the individual layer image data based on the resolution data corresponding to the identification data to create and record the matching layer image data. As a result, even if the user changes the information terminal, based on the data combining the user and the information terminal, the already created individual layer image data can be converted to the individual layer image data adapted to the information terminal (adaptive layer image data). Adjustments can be processed and created. This processing can be performed by the centralized control computer 1. Further, in the present system S, (7-2) information in which terminal identification data in which matching layer image data is associated with user identification data is recorded It also has a step of transmitting to the terminal. This makes it possible to achieve the above effects. In this way, when a layer image is created by one user using a certain information terminal, the computer for centralized control 1 creates matching layer image data while confirming the resolution of the user and the information terminal, and the user Even if the user changes the information terminal, it is possible to display the optimum layer image on the information terminal. Furthermore, if the user wants to share the layer image data created by him/herself, the centralized control computer 1 can create and transmit suitable layer image data to match the information terminals of all users in this system S. becomes.

Also, in this case, even if the individual layer image data includes characters, etc., it is preferable to extract and record the text information in the same manner as the common image data.

Moreover, in this system S, the colors that can be displayed may differ for each information terminal. Therefore, (8) the displayable color data is also recorded in each of the plurality of information terminals 2, and the display color of the common image data is adjusted based on the displayable color data of each of the plurality of information terminals 2, and the display colors of the plurality of information terminals 2 are adjusted. Preferably, the step of creating and recording a plurality of matching common image data that are compatible with each other is also performed. This allows information about color as well as resolution to be included.

As described above, the system S is a screen display centralized management system that enables display suitable for each information terminal regardless of the information terminal. This system can be applied in various fields, and examples of systems using a centralized control computer and a plurality of information terminals include a class system, a conference system, a conference room reservation system, an ensemble sheet music system, The present invention can be applied to a bus stop signboard system, a store price tag display system, etc., but is not limited thereto.
