Description

  The present invention relates to an image display device, and more particularly to an image display device in which a display decorative member can be installed.

  Conventionally, favorite photo prints are put in a photo stand (photo stand) and decorated indoors. On the other hand, in recent years, an electronic photo stand adapted to electronically display image data has been known in much the same manner as a photographic print placed in a photo stand.

  As an example of such a technique, Japanese Patent Application Laid-Open No. 2005-56029 reads information of a non-contact type IC memory embedded in an image print in which an image is printed in a non-contact manner, and is printed on the image print. An electronic photo stand is described as a display device that electronically displays the same image as the above.

  By the way, many photo stands for photographic prints have been designed in various ways to enhance the decorativeness of photos. On the other hand, for an electronic image, a technique is known in which image data and a template image are combined to enhance decorativeness.

  As such a technique, for example, Japanese Patent Application Laid-Open No. 2001-268338 describes a technique in which a template image is decomposed into partial images and stored, and a variety of template images are created by combining these images. It is designed to enhance individual decoration.

By the way, in an apparatus that electronically displays an image, it is widely known that a screen burn may occur when the same image is displayed for a long time. For this reason, in many conventional electronic image display devices, a function of updating the display of the entire screen at a constant cycle is implemented to take measures to prevent burn-in.

  First, the display decoration member 3 is configured, for example, by attaching a wireless IC tag 22 as a storage means having a minute chip shape to a display decoration member main body 21 having a shape as shown in FIG. In FIG. 5, the wireless IC tag 22 is illustrated as if it is provided so as to protrude from the outer surface of the display decoration member main body 21. Embedded. The wireless IC tag 22 indicates the shape and size of the display decoration member 3, the shape, size and arrangement of the image passing window as described above, or what kind of application the display decoration member 3 is suitable for. Information, etc. are described. The information stored in the wireless IC tag 22 will be described in detail later with reference to a specific example.

  The image display device 2 includes a monitor 5, a CPU 11, a recording medium 12, an image reading control unit 13, a RAM 14, a display control unit 15, a wireless IC tag reader 16, and an antenna unit 17.

  The monitor 5 is image display means that includes the liquid crystal monitor 5a and the illumination device 5b as shown in FIG.

  The recording medium 12 is composed of, for example, a non-volatile storage means such as a small hard disk or a flash memory, and is for accumulating and storing a plurality of image data (image data group). The recording medium 12 records not only the image data group but also related information (for example, a keyword related to the image data (more specifically, the keyword “family ( Family) ”and the keyword“ travel ”for travel photos, etc. Other examples of keywords include season, sea, mountain, birthday, etc., which can be widely adopted. )), And a database indicating image data classification (for example, classification according to vertical and horizontal positions of photographs, classification according to keywords, and the like). Note that the recording medium 12 is not limited to a recording medium fixedly provided in the image display device 2 and may be a detachable recording medium such as a memory card. Alternatively, in place of or in addition to the recording medium 12, a network control unit such as a wired LAN, a wireless LAN, and IEEE1394 is further provided, and communication is performed by connecting to the network. The image data may be read from the image data server.

  The image reading control unit 13 is a control unit that performs control of extracting an image to be displayed from a plurality of images recorded on the recording medium 12 and transferring the extracted image to the RAM 14 under the control of the CPU 11. When a removable memory card, for example, is used as the recording medium 12, a memory card control unit is employed as the image reading control unit 13.

  The RAM 14 is used as an image buffer for storing image data read by the image reading control unit 13, and stores a processing program executed by the CPU 11, or stores various data used by the CPU 11. It is also used to do.

  Since the image data recorded in the recording medium 12 is not necessarily in a form suitable for display on the monitor 5, the CPU 11 performs predetermined image processing on the image data stored in the RAM 14. Thus, data for display is generated. Further, the CPU 11 performs image processing so as to be suitable for the display mode based on information on the display mode (for example, monochrome, sepia, painting style, etc.) stored in the wireless IC tag 22 as will be described later. Although the CPU 11 performs image processing here, the present invention is not limited to this, and a dedicated hardware engine capable of performing high-speed processing (for example, read image data is JPEG-compressed image data). In this case, image processing may be performed using a hardware engine that performs JPEG decompression) or the like.

  The display control unit 15 is a control unit that controls the display data stored in the RAM 14 to be displayed on the monitor 5 in accordance with a predetermined timing based on the control of the CPU 11.

  The antenna unit 17 is a communication for acquiring information stored in the wireless IC tag 22 provided on the display decoration member 3 by performing non-contact communication (for example, wireless communication) with the wireless IC tag 22. It is a means and an information acquisition means.

  The wireless IC tag reader 16 is an information acquisition unit for analyzing a signal obtained via the antenna unit 17 and acquiring information stored in the wireless IC tag 22.

  The CPU 11 is a control unit that controls the entire image display device 2 including the above-described components based on information acquired by the wireless IC tag reader 16.

  6 is a diagram showing another example of the display decoration member 3, and FIG. 7 is a diagram showing an example of information stored in the wireless IC tag 22 of the display decoration member 3 as shown in FIG. .

  A specific example of information stored in the wireless IC tag 22 will be described with reference to FIGS. 6 and 7.

  First, it is assumed that the display decoration member 3 is configured as shown in FIG. That is, on the rectangular display decoration member 3, four star-shaped image passing windows 3f, 3g, 3h, 3i are arranged in a diagonal direction from the upper left to the lower right.

  Further, a circular image passing window 3j is provided at the upper right of the display decorative member 3, and an image passing window 3k having a horizontally long rectangle is provided above the center of the display decorative member 3.

  It is assumed that the following display is expected to be performed on the display decoration member 3.

  First, the image passing windows 3f, 3g, 3h, and 3i are used to display different images, respectively, but are displayed so that the images sequentially move in a cycle of 3 seconds from the upper left to the lower right. Updates shall be made. Specifically, an image displayed on the image passage window 3f at a certain time is displayed on the image passage window 3g three seconds later, and further displayed on the image passage window 3h three seconds later, etc. Shall be. Thereby, it is possible to obtain a reproduction effect like a shooting star.

  The image passing window 3j picks up image data at random and displays it with an update period of 10 seconds.

  Furthermore, the image passing window 3k is an area where the attached information of the image displayed on the image passing window 3j can be displayed. Specific examples of the attached information include shooting date and time, comments designated by the user, and the like.

  For example, information shown in FIG. 7 is stored in the wireless IC tag 22 of the display decorative member 3 having such a configuration and display mode. For convenience of illustration, information is shown in two columns in FIG.

  First, the first line of information indicates that the language in which the information is described is XML version 1.0 and is described as text using Shift JIS characters.

  The portion from the next <DECORATION> to the last </ DECORATION> describes information relating to the decoration state of the display decorative member 3. Note that there are always tags that are enclosed in <>, with some exceptions, and tags that indicate the end of the range are appended with / to tags that indicate the end of the range. It has become.

  The tag <BODY> (from tag to tag </ BODY>, hereinafter, description of the tag indicating the end of the range is omitted) is a part in which information relating to the shape and the like of the display decorative member main body 21 is described.

  The tag <SizeWidth> describes “240”, which indicates that the width of the display decorative member body 21 is 240 mm.

  The tag <SizeHeight> describes “180”, which indicates that the height of the display decoration member main body 21 is 180 mm.

  Here, mm is used as a unit indicating the size of the display decorative member main body 21, but other units may be used, and a unit may be designated.

  The tag <Keywords> is a part that can be set as an option, and is a part that describes a keyword used for extracting a specific image from the image group. In the example shown in FIG. 7, “family” (family) is described as a keyword. Therefore, an image related to “family” in the image group recorded on the recording medium 12 is displayed on the image display device 2 to which the display decoration member 3 is attached.

  The subsequent tag <PARTS> is a part for describing information relating to each image passing window of the display decoration member 3, and one image passing window is described by the tag <PART>.

  The first tag <PART partid = "A001"> describes information about the image passing window whose part ID is "A001". Here, the part ID “A001” is assigned to the image passing window 3j.

  The tag <PositionWidth> indicates the horizontal coordinate of the center position of the image passing window 3j, and the tag <PositionHeight> indicates the vertical coordinate of the center position of the image passing window 3j. Here, the center coordinates are ( 190, 40).

  The tag <SizeWidth> indicates the width of the image passing window 3j, and the tag <SizeHeight> indicates the height of the image passing window 3j. Here, the width is 50 mm and the height is 50 mm. Note that, as shown in FIG. 6 and the like, the image passing window is not necessarily a rectangle having each side parallel to the four sides of the display decorative member 3, so that the width and the height are the maximum in the horizontal direction. Large and vertical maximum heights are listed respectively. As a result, it is possible to display a (somewhat large) image including the display range of the image passing window on the monitor 5 of the image display device 2.

  A tag <Attribute> describes an attribute of information to be displayed. Here, the type and shape of display information are described, “image” indicates that image information should be displayed on the image passing window 3j, and “circle” indicates that the shape of the image passing window 3j is circular. Respectively.

  A tag <Relation> describes a parent-child relationship between image passing windows. When “0” is described in this part, it means “parent”. On the other hand, in the case of “child”, the parent part ID is described here.

  A tag <Interval> is a portion for recording a display update cycle in units of 1 millisecond (1/1000 second). Here, since “10000” is recorded, this means that the display is updated every 10 seconds.

  The subsequent part ID “A002” describes information related to the image passing window 3k. Since the tags in this part are the same as described above, only the description information will be described here. In this part, the image passing window 3k has a rectangular shape with a center coordinate (120, 25), a width of 50 mm, and a height of 10 mm, and displays text information related to the image reproduced in the part ID “A001”. It is stated that it should be. In addition, “0” is described in the update period column, which means that it follows the update period of the parent image passing window 3j.

  Further, the part with the next part ID “B001” describes information related to the image passing window 3f. In this part, the image passing window 3f has a pentagram shape with a center coordinate (50, 60), a width of 40 mm and a height of 40 mm, should display an image, and is a “parent”, and has 3 seconds. It is described that the display is updated at a period of.

  In the next part ID “B002”, information relating to the image passing window 3g is described. In this part, the image passing window 3g has a pentagram shape with a center coordinate (100, 90), a width of 40 mm and a height of 40 mm, and an image of the “parent” part ID “B001” is displayed after 3 seconds. It is stated that it should be. That is, the CPU 11 controls the display order or the frame destination based on such information.

  In the case of the display decoration member 3 having the shape as shown in FIG. 6, the part of the part ID “B003” corresponding to the image passing window 3h and the part of the part ID “B004” corresponding to the image passing window 3i are further included. However, it is almost the same as the part ID “B002” described above (the center coordinates are different from the parent-child relationship, and the parent of the part ID “B003” has the part ID “B002” and the part ID “ Since the parent of “B004” is the part ID “B003”), the illustration and description thereof are omitted here.

  The image display device 2 receives such information recorded on the wireless IC tag 22 of the display decoration member 3 via the antenna unit 17 and the wireless IC tag reader 16, and the CPU 11 analyzes the received content, Appropriate playback processing is performed.

  Here, an example has been described in which XML data recorded basically as text data is exchanged. However, XML data may have limitations on expressive ability and execution ability. For example, when high-speed animation is executed with some animation character appearing, it is difficult in terms of processing capability to execute while analyzing XML information. In order to cope with such a case, it is conceivable that the information stored in the wireless IC tag 22 is a binary program that can be directly executed by the CPU 11 of the image display device 2. When such a means is adopted, it is not necessary to perform analysis by the CPU as in the case of XML information, so that high-speed processing is possible.

  Next, FIG. 8 is a diagram illustrating a configuration example of the illumination device 5 b of the monitor 5.

  The illuminating device 5b is configured by arranging backlights 5b1 to 5b9 as a plurality of illuminating means in a vertical 3 × 3 horizontal direction, and each backlight is included in the entire display area of the liquid crystal monitor 5a. It is configured to illuminate a rectangular partial area of about 1/9. And each backlight 5b1-5b9 is comprised so that each can control ON / OFF independently.

  Here, for example, if the display decoration member 3 as shown in FIG. 6 is attached to the image display device 2, the information on the wireless IC tag 22 as shown in FIG. It can be seen that there is no image passing window at the corresponding position, and there is no need to display an image. Therefore, when such an analysis result is obtained, the CPU 11 controls the backlight 5b7 to be turned off via the display control unit 15. Thereby, unnecessary power consumption can be reduced.

  By the way, the display decoration member 3 can be replaced with various types as shown in FIG. At this time, the display decoration member 3 may include a type that covers the entire display area of the liquid crystal monitor 5a, that is, a type in which no image passing window is provided. In this type of display decoration member 3, information indicating that no image passing window is provided in the wireless IC tag 22 is recorded as, for example, the XML information described above. When the display decoration member 3 without such an image passage window is attached to the image display device 2, the CPU 11 performs an XML information analysis to recognize that there is no image passage window, and turns off the illumination device 5b. To control. In the configuration example shown in FIG. 8, all the backlights 5b1 to 5b9 are controlled to be turned off. However, even if it is the illuminating device 5b comprised by the single backlight, it is good to make it control off similarly.

  At this time, not only the illumination device 5b but also the liquid crystal monitor 5a, the display control unit 15, the recording medium 12, and the image reading control unit 13 may be turned off. Thereby, further power saving can be achieved. However, since it is necessary to detect when it is replaced with the display decoration member 3 provided with the image passing window, the antenna unit 17, the wireless IC tag reader 16, the CPU 11, and the RAM 14 are in an idle state ( It is necessary to supply power that can maintain a standby state in which a transition to the execution state can be maintained.

  By adopting such a configuration, it is possible to substantially turn on / off the power source of the image display device 2 by replacing the display decoration member 3, and the operability can be improved. At this time, it is possible to eliminate the need for a power switch (to completely turn off the power, the outlet connected to the image display device 2 may be removed or the battery may be removed).

  Only the display decoration member 3 provided with no image passage window is rotated and installed on the front side of the monitor 5 via a hinge or the like, unlike the other display decoration members 3 provided with the image passage window. You may make it get. Thereby, the operativity for powering off can be improved. At this time, there is a possibility that the display decoration member 3 not provided with the image passage window is placed on the front side of the display decoration member 3 provided with the image passage window. Accordingly, the CPU 11 acquires information about the plurality of display decoration members 3 via the antenna unit 17 and the wireless IC tag reader 16, and at least one of them relates to the display decoration member 3 in which no image passing window is provided. In this case, the power is controlled to be turned off regardless of the information of the other display decoration members 3.

  Next, FIG. 9 is a flowchart showing processing executed by the CPU 11 of the image display device 2.

  When the image display device 2 is turned on (for example, connected to an outlet or loaded with a battery), the display decoration member 3 is mounted on the front surface of the monitor 5 after checking the RAM 14 and performing other necessary initial settings. It is determined based on information from the wireless IC tag reader 16 whether it is attached to the side (step S1).

  Here, when the display decoration member 3 is not attached, it shifts to the full screen display mode (step S2). During execution of this full-screen display mode, detection of information of the wireless IC tag 22 via the wireless IC tag reader 16 is repeatedly performed at appropriate time intervals, and the display decoration member is based on the detected information. If it is detected that 3 is attached, an interrupt (indicated by the symbol “I” circled in FIG. 9) is generated, and this full-screen display mode is terminated, and the steps described above are performed. The process proceeds to S1. Further, the detection of the attachment / detachment of the display decoration member 3 is not limited to being performed via the wireless IC tag reader 16, but may be detected by providing a switch or the like.

  If it is determined in step S1 that the display decoration member 3 is attached, information on the wireless IC tag 22 is acquired via the wireless IC tag reader 16 (step S3).
