In addition, when dot matrix display is performed on an image display device such as a liquid crystal panel in which image display is constantly updated electrically unlike paper media, the dots of the image and the pixels of the display device are made to correspond one-to-one. There is a technique of displaying the protruding portion by scrolling or displaying the enlarged portion of the display image.

An information writing system has been proposed in which an image recorded on a rewritable recording medium can be obtained as digital information as needed, and for example, reprocessing and reuse can be easily performed (Patent Document 1). reference.).
In this information writing system, a medium writing device acquires image information to be written on a recording medium, converts the information into a writable format, and writes the information on the recording medium. The ID acquisition unit acquires a medium ID from the recording medium or by user input. Information indicating the location of the medium ID and the written image information is sent to the server and stored as index information in which the two are associated with each other. When reusing the image information written on the recording medium later, if the medium ID is specified and the index information is acquired from the server, the original image information can be acquired, and reuse and reworking are easy. It can be carried out.

In addition, there is a system that makes it possible to manage and further analyze user actions related to the use of content such as content display processing on a portable display recording medium and delivery of a portable display recording medium between users. It has been proposed (see Patent Document 2).
In this system, when a user acquires display content from a content providing apparatus using a portable display recording medium, the user ID, the device ID of the portable display recording medium, the content ID, and acquisition time information are notified to the management apparatus. Record in the device log DB. The display content switching by the portable display recording medium is similarly notified and recorded in the log DB. Then, the log DB is searched by the search device, and for example, by using the user ID as a key, the transition of which portable display recording medium a certain user has owned and the transition of which content has been used are grasped. be able to.

In addition, a display information management system has been proposed that can flexibly cope with changes in display contents with an inexpensive configuration and that can grasp display contents in real time (see Patent Document 3).
The display information management system includes a host computer to which a display recording medium, an information reading / writing device, a wireless communication unit, and a storage are connected, and that can exchange information via the information reading / writing device and the wireless communication unit. It is configured. A medium identification code, a display information identification code, and display information are recorded on the display recording medium. The code information reading unit reads the medium identification code and transmits it to the host computer. When there is a rewrite request, the information writing unit writes the display information identification code and the display information transmitted from the host computer to the display recording medium.

FIG. 1 shows the configuration of an information management system according to this example.
The information management system includes a display recording medium 1 in which an image is formed so that it can be rewritten in accordance with a writing external force and the formed image is displayed and retained after the writing external force is removed, and a setting stored in the display recording medium 1 Information management and an information management device 2 that writes external images to the display recording medium 1 by applying a writing external force to the display recording medium 1 are configured.

The display recording medium 1 includes a display unit 11 that displays and holds a written image, and a storage unit 12 that stores setting information that can be used for various managements in an externally readable and writable manner. Yes.
The display recording medium 1 is a thin and flexible device like paper, and is also called electronic paper. The display unit 11 can employ various modes depending on the image writing method. Those that drive the element by directly applying external force such as electricity, magnetism, heat, etc., those that drive the element by changing the voltage accompanying light irradiation, changing the color state by changing the pH of the liquid accompanying applying voltage, etc. You may use the display principle which drives an element in a chain. Further, a full-surface rewriting method, a line rewriting method by moving a recording head, an electric scanning rewriting method by simple matrix driving or active matrix driving may be used.

For example, the display unit 11 of the method of electrically writing an image encloses fine colored charged particles between a pair of front and back matrix electrodes that are transparent at least on the front side, and this is a pair of front and back film substrates that are transparent at least on the front side. The sandwiched structure is configured such that black colored particles and white colored particles remain on the opposite surfaces of the front and back sides of the display medium when the electrodes are applied positively or negatively.
Therefore, in a state where no voltage is applied to the electrode (no power supply state), negatively charged white particles are accumulated on the back surface side, while positively charged black particles are accumulated on the front surface side, and the display unit 11 is moved from the front surface side. It becomes black when visually observed. When the electrode polarity of the required part of the matrix corresponding to the image to be displayed based on the electronic data is inverted, the positional relationship between the white particles and the black particles is switched, and an image based on the contrast between the white particles and the black particles is displayed. Is done. Note that by operating the matrix electrode based on different electronic data, the displayed image can be switched depending on the contrast between the white particles and the black particles, and can be reused many times.

  Further, for example, the display unit 11 of the method of writing an image by light includes an organic photoconductive material layer (organic photoconductive layer) and a liquid crystal display material layer (microencapsulated cholesteric liquid crystal) used in a copying machine. Layer) is sandwiched between a pair of front and back transparent electrodes, and this laminate is sandwiched between a pair of front and back transparent substrate films and transferred to a light control panel (light emitting panel) for image writing. When an image is displayed and projected on the display unit 11 and a voltage is applied to the electrodes, the intensity of light is instantaneously converted to a reflection density so that the projected image is held even after the voltage is removed. Then, an image displayed and held can be erased by applying an erasing voltage to the electrode, and can be reused many times by repeating writing and erasing.

The storage unit 11 can adopt various modes according to the method for reading or writing the setting information.
For example, the storage unit 11 includes a memory that stores the setting information as electronic data, and a communication function that transmits or receives electronic data stored in the memory in response to an external wireless or wired access. be able to.

  As setting information stored in the storage unit 11, for example, user information that identifies a user of the display recording medium 1, medium information that identifies the display recording medium 1, and content that identifies content that can be written to the display recording medium 1 Various information that can be used for system management, such as information, format information that specifies the display format of an image to be written on the display recording medium 1, and device information that specifies an information management apparatus that can be used by the display recording medium 1 is used. It is done. As the user information, any of those related to the use of the system can be set. For example, information on the person who owns or forms the display recording medium 1 or information on the display recording medium 1 can be viewed. Each person's information etc. can be set up individually or in combination.

Information indicating the display format. In other words, it is information used to determine the appearance of the image when the original data constituting the image is displayed on the display unit 11 of the display recording medium 1, and is used to specify the data internal structure of the electronic file. The file format is different.

  The format information for designating the display format includes, for example, the image display capability of the display recording medium 1 itself, such as the size of the display unit 11, the resolution of the display unit 11, and whether or not the display unit 11 can perform color display. Display that allows the user to arbitrarily specify the display format of the image, such as designation of the display magnification of the image, designation of writing and displaying a plurality of pages of images in a single page, designation of displaying a color image as a monochrome image, etc. Information relating to image processing conditions can be employed.

  It is assumed that many electronic papers are used in the same shape and are separated and used at the same time, and in order to improve the feeling of use, the appearance of the device is often manufactured in a similar manner to the others. For example, it is formed as a white paper-like medium of A4 size. On the other hand, for each electronic paper, the resolution and the number of colors are different, or even if the resolution and the number of colors are the same, the display format must be set differently in order to display a variety of effective displays. Is possible. Therefore, as the use of electronic paper progresses, it becomes more difficult to predict which medium will express information in what format. Therefore, in this case, the usefulness of the management system that reads and displays the format information for designating the expression format and allows further changes is increased.

  The display recording medium 1 is used by storing setting information in the storage unit 12, and the setting information stored in the storage unit 12 is any one of the above-described user information, medium information, content information, format information, or the like.
