JP5874258B2 - Large paper browsing system - Google Patents

Description

  The present invention relates to an image processing apparatus that displays a large sheet of digital data on a portable terminal.

  Along with the development of Internet technology, electronic commerce providing products and services via a network is expanding. In recent years, infrastructure of communication lines has been improved, and high-speed communication means can be used. With this, especially at sites such as stores and manufacturers that sell over-the-counter at the same time as electronic stores, these paper images of flyers and catalogs originally distributed on a paper basis are converted into digital data and presented to customers. There is a movement to unify information.

  However, since the amount of image data in flyers and catalogs is large, the smooth viewing of these images is limited to environments where high-speed communication means can be used. For example, data communication by wireless communication has been accelerated. Although it is possible, there may be a case where it is not possible to obtain a communication speed sufficient for receiving large image data due to the reception environment such as the geographical position of the receiver and the congestion situation. Further, when the receiving side is a device with a small screen such as a mobile phone or a portable information terminal, it is necessary to cope with a method of displaying a large image such as a flyer or a catalog.

  According to the image display method disclosed in Patent Document 1 below, there are several types of paper images from a low resolution to a high resolution for a reception target having a large screen size and data amount such as the image of the above-described flyer or catalog. Is converted into digital data at the resolution of the image, and the image is further divided into a capacity suitable for communication, and the image data is acquired by a program (viewer) that operates on the user's mobile phone or Web browser of the personal digital assistant if necessary. And display the image in an operable state. In addition, when an image area to be displayed is moved by an operation such as scrolling or enlargement / reduction, image data necessary for display is newly calculated each time. If there is unacquired image data, the image data is calculated. A method is known in which data is automatically acquired unconditionally and displayed on the screen of a user terminal.

JP 2004-320534 A

  However, when the area of the image to be displayed is moved by an operation such as scrolling or enlarging / reducing, the image data to be acquired is automatically acquired unconditionally by the method of automatically acquiring image data necessary for display. If there are many cases or if the line speed is limited, the speed until the screen is displayed will be slow. In addition, in the case of scrolling, the determination as to whether or not a new display area should be displayed with the same resolution as before has not been considered.

  In addition, the original paper image is converted into digital data in advance with several kinds of resolutions (eight kinds according to the embodiment of the invention of the above-mentioned Patent Document 1), divided into files having a capacity suitable for transmission, and stored in the server. In this method, a considerable number of files are managed and a corresponding storage area is required.

In order to solve the above problems, the first invention of the present application is a transmission / reception means for receiving a request from a user terminal device through a network and returning corresponding information, and image data for one page is a single file. A base image database that can store relatively low-resolution base image data that can be searched, and high-resolution detailed image data that consists of multiple files of image data for one page of the paper. A detailed image database accumulated in the form, a paper surface selection means for providing the user with a list of paper surfaces that can be presented, and a base image data for one paper surface by a request relating to transmission of the base image from the user terminal device, and a base image providing means for providing a region division information and the name of the detailed image data of the detailed image data of the paper surface, from the user terminal Details image providing means for providing detailed image data to the user terminal on request in accordance with the transmission of detailed image data, and the receiving data management means for adding, updating, deleting maintenance of those paper of digital data, each of said means The user terminal device executes a viewer program to send a request for transmission of a base image to the large paper image server device through a network, and includes base image data and a receiving means for receiving a file name and the detailed image data for identifying the area division information and the detail images of detailed image data of the paper surface, the screen of the user terminal device by tiling to overlap the detailed image data to said base image data displayed in, zooming, and browsing means for performing scrolling operation, the zooming operation If display using base image data exceeds a specific magnification I, and detailed image notifying means for displaying on the terminal screen that the detailed image is present, the acquisition of detailed image in response to the notification of the presence of detailed image When the above request is made , the large paper page browsing system includes a computer that operates as detailed image requesting means for requesting transmission of detailed image data from the large paper image server apparatus. The detailed image data requested to be transmitted by the detailed image requesting unit does not need to request to transmit all the detailed image data corresponding to the corresponding base image data at once, but is necessary for screen display. You may request to send a portion.

Further, the detailed image notification means of the viewer program displays on the terminal screen that the detailed image exists when the scrolling operation is stopped for a certain period of time and when the scaling operation has exceeded a certain enlargement ratio. Also good.

Further, the detailed image notification means of the viewer program automatically transmits the detailed image data to the large page image server device when the scroll operation is stopped for a certain period of time and the magnification operation has exceeded a certain enlargement ratio. It is also possible to call detailed image requesting means for requesting.

  According to the first invention of the present application, the base image data for one paper surface, the area division information of the detailed image data on the paper surface, and the name of the detailed image data are first transmitted to the viewer. Is displayed on the screen of the user terminal. Since this base image has a resolution that can withstand a certain degree of enlargement, the base image has sufficient image quality for rough browsing. In addition, the apparatus has detailed image data with the highest resolution, and the user can arbitrarily select to load and display this data, thereby reducing stress caused by insufficient resolution of the image.

  According to the present invention, when there is unacquired detailed image data when scrolling a high-resolution detailed image, acquisition of the image data may be left to the user's selection. For this reason, it is unlikely that the user feels the slow speed of the screen display related to the automatic reading of data that has been associated with the conventional image display method.

  According to the present invention, the image data for one page of the leaflet and the catalog paper is two types of low resolution base image data and maximum resolution detailed image data, and images of several types of resolution as in the conventional image display method. There is no need to retain data.

  According to the present invention, a paper image distributed on a paper basis similar to that used in ordinary commercial transactions can be presented as it is in electronic commercial transactions and the like. Thereby, unification of leaflet and catalog production can be aimed at.

FIG. 5 is a diagram illustrating an example of a base image and a detailed image. The base image is composed of one file on the database, and is image data that is loaded into the viewer by the base image providing unit 132 in response to a request for transmitting the base image from the viewer. For example, a size of about 1000 pixels × 750 pixels is suitable as shown in the figure. With such a number of pixels, it is possible to expect a level of image quality that can be visually recognized even when enlarged by about 200% on the viewer. The detailed image is image data of the highest resolution and is usually composed of a plurality of files (in the example, divided into 25 files) on the database. The detailed image request means 232 of the viewer requests transmission of the detailed image data. If so, the detailed image data designated by the detailed image providing means 133 is loaded into the viewer. At this time, the detailed image requesting unit 232 may transmit all the detailed image data related to the corresponding base image, or may request to transmit a part of the image data necessary for screen display. As shown in the example of the figure, the size of one divided detailed image data is preferably about 800 × 600 pixels in consideration of the data transfer speed . As shown in the example of the drawing, when the maximum resolution of one page is 4000 pixels × 3000 pixels, it is possible to cover the size of a newspaper page spread at 200 lines / inch and approximately one page of newspaper page and 133 lines / inch.

  FIG. 6 is a diagram for explaining display of a detailed image. The base image is displayed on the viewer at the beginning of the request to view a large page. After that, when the display screen is enlarged in the viewer, the viewer analyzes the area division information of the detailed image data and notifies the user that the detailed image exists as shown in the left image of FIG. The description will be described later. Further, when the user requests to display a detailed image, the detailed image data is loaded and displayed as shown in the right image of FIG.

    FIG. 7 is a block diagram showing a request from the viewer and the behavior of the large-size paper image server 100 according to the present invention. The service user accesses the large page image server 100 of the large page image distribution site of the present embodiment through the network 500 using the viewer of the user terminal owned by the service user. When an inquiry is made about a large paper page that can be viewed (S01), the control means 120 activates the paper surface selection means 131. The page selection means 131 creates a screen that presents a list of large pages that can be browsed, and transmits it to the viewer to display the screen (S02). In addition to the name of the page, the display data includes a base image and a detailed image. Information is included.

  Using the viewer, the service user transmits a file name, a path name, a URL name, and the like of the page to be browsed from the presented list of large pages that can be browsed to the large page image server 100 (S03). At this time, the control unit 120 operates the base image providing unit 132. The base image providing unit 132 transmits the base image data, the area division information of the detailed image data on the page, and the name of the detailed image data (abbreviated as accompanying information in the drawing) from the base image database to the viewer (S04).

  The service user browses the base image using the viewer. At this time, the viewer function enlarges / reduces or scrolls the display screen, but the enlargement operation is performed during browsing, and as a result, the enlargement ratio of the base image is predetermined. If it exceeds the value (for example, 200%), there is a concern that the image quality becomes coarser if it is enlarged, so whether or not the detailed image data exists for the screen, the region division information of the detailed image data acquired together with the base image data If detailed image data exists, the viewer overlays a “detailed” button on the currently displayed screen (S05). Here, when the enlargement ratio of the base image returns to a predetermined value (for example, 200%) or less by the user's operation, the viewer cancels the “detailed” button display.

  Moreover, you may perform another procedure by FIG. 8 as a 1st modification. According to this, the service user browses the base image using the viewer. At this time, the viewer function enlarges / reduces or scrolls the display screen, but the scroll operation is interrupted for a certain period of time (about 2 seconds). If the image enlargement ratio exceeds a predetermined value, it is predicted that the user has a high probability of gazing at the part, and whether detailed image data exists for the screen, When the detailed image is calculated based on the area division information of the detailed image data acquired together with the base image data, the viewer displays a button with “detailed” overlaid on the currently displayed screen (S15).

When the user clicks this button while the “Detailed” button is displayed on the viewer, the viewer activates the detailed image requesting unit 232 and transmits the detailed image data to the large-sized paper image server 100. Is requested (S06, S16).

Moreover, you may perform another procedure by FIG. 9 as a 2nd modification. According to this, the service user interrupts the scroll operation for a certain period of time while browsing the base image using the viewer (preferably about 2 seconds), and if the image enlargement rate exceeds a predetermined value, Predicting that the person is gazing at that part is high and calculating whether the detailed image data exists for the screen from the area division information of the detailed image data acquired together with the base image data, and the detailed image exists. In this case, the viewer activates the detailed image requesting means 232 and automatically requests the large-sized paper image server 100 to transmit detailed image data (S25).

  When receiving the request for transmission of the detailed image data, the large page image server 100 operates the detailed image providing unit 133. The detailed image providing means 133 receives this and transmits the detailed image data to the viewer (S07, S17, S26).

  After that, when the user performs a scroll operation and as a result, the display area has moved to a range where the detailed image data has not yet been loaded, the processes after steps S05, S15, and S25 are repeated. However, in order to reduce the amount of data to be transmitted, the viewer does not request acquisition of detailed image data that has already been received.

FIG. 10 is a diagram for explaining reading of the divided detailed image data file in the detailed image display. When the area where the detailed image is already displayed is the “display area” on the left side of FIG. 10, the detailed image data files 1, 2, 6, 7, 11, and 12 are loaded in the viewer. Detailed images can be displayed. If the display area is subsequently changed by scrolling the viewer, the base image is displayed for the portion where the detailed image is not yet loaded, and the detailed image notification means 231 notifies the user that the detailed image exists. Is done. At this time, when a request for reading a detailed image is newly made, the detailed image data files Nos. 8, 13, 17, and 18 except the already loaded detailed image data files Nos. 7 and 12 are loaded into the viewer ( (See “Display Area” on the right of FIG. 10). In this case, all the divided detailed image data files that are no longer included in the new display range and have already been read by the viewer are left behind and not deleted.

  According to the present invention, even in electronic commerce and the like, large paper images such as paper-based leaflets, catalogs, and newspapers that are distributed in normal commerce are presented to the user without imposing a heavy load. It is possible to unify large-scale paper production such as flyers, catalogs, and newspapers.

  The present invention is not limited to the above-described embodiments, and various modifications and applications can be made within the scope of the claims. For example, in the present embodiment, a mobile phone or a mobile terminal is illustrated as a user terminal on which a viewer operates, but the present invention can be similarly applied to a desktop personal computer or an electronic book.
