Display control means for controlling the image display means to display an image in an area other than the non-display area.

The setting means may be configured to set the non-display area according to an operation instruction.
In this image reproduction device, for example, a touch panel may be provided on the front side of the image display means as a member for the operation instruction for setting the non-display area.

  The display control means is configured to control to display an image in a display permission area which is an area other than the non-display area, for example, according to the size of the display permission area and the number of images to be displayed.

For example, it is preferable that the image display unit is configured in a thin plate shape and includes a grip portion on a side portion of the image display unit.
In that case, for example, it is preferable to include image storage means for storing an image inside the grip portion.

Next, the display method in the image reproducing device according to the second aspect of the present invention displays light on the front side, transmits light from the back side to the front side, and has light transmissivity so that the back side can be seen from the front side. In a display method in an image reproduction apparatus including an image display means, a signal transmitted from the rear side entity is received by a plurality of receiving units arranged on a screen of the image display means, and the distribution of the received signal Based on the above, a range that can be seen through the substance on the back side in the screen of the image display means is set as a non-display area that does not display an image, and an image is displayed in an area other than the non-display area Configured to control.

ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the image reproduction apparatus which displays in a transmissive | pervious image reproduction apparatus so that the visual recognition of the background entity may not be prevented .

  Embodiments of the present invention will be described below with reference to the drawings.

The image processing unit 17 is instructed to display at a predetermined position.

  Further, when there is an audio data file related to the image data file of the image displayed on the image display unit 2 in the data folder of the memory card 7, the B-CPU 14 sends the above data from the speaker 5 via the audio output unit 24. The voice processing unit 16 is instructed to emit voice based on the voice data file.

  FIG. 3 is a diagram showing an arrangement configuration of nine antennas 25 (25-1 to 25-9) for detecting the position of the wireless tag 13 in the transparent viewer 1, with the transparent viewer 1 on the right. The schematic side view is shown, and the rear view is shown on the left.

  As shown in FIG. 3, the image display unit 2 of the transparent viewer 1 has a touch panel 23 superimposed on a front surface 2-1, and transparent electrodes are looped on a rear surface 2-2. Nine loop antennas 25 are formed at the corners of a partition grid, which will be described later, at equal intervals.

  In the state shown in FIG. 1, these nine loop antennas 25 are signal radio waves of link information transmitted from the wireless tag 13 of the seal 14 attached to the ticket 10 that has been attached to the sheet 11 and stored. Are received respectively.

  The ticket 10 is not limited to being stored on a sheet 11 such as a scrapbook page, and may be stored in a bag with an explanatory label or the like. In this case, the ticket 10 taken out from the bag is placed on a desk or the like and viewed through the transparent viewer 1 from above.

  The B-CPU 14 and the nine loop antennas 25 shown in FIG. 2 recognize the position of the wireless tag 13 and the position where the ticket 10 is located by the strength of the signal radio wave received from the wireless tag 13 respectively. The position, that is, the range where 10 is present is set in the non-display area of the display image.

  FIG. 4 is a diagram for explaining a method for setting a range in which the ticket 10 is present in the non-display area of the display image according to the strength of the signal radio wave from the wireless tag 13. As shown in the figure, the image display unit 2 of the transparent viewer 1 is partitioned so that there are six grids in each of the vertical and horizontal directions.

  The loop antenna 25-5 shown in FIG. 3 is arranged at the center of the image display unit 2 where the four corners of the center are gathered. Then, the loop antennas 25-1, 25-2, 25-3 shown in FIG. 3 are provided at eight places where the corners of a set of four surrounding the four squares around the center in the counterclockwise direction gather. 25-6, 25-9, 25-8, 25-7, and 25-4, respectively.

  Now, in the state shown in FIG. 1, the nine loop antennas 25 (25-1 to 25-9) set the reception intensity of the signal radio wave received from the wireless tag 13 to H (high), L (Low) and As shown in FIG. 4, the strength of the signal radio wave received from the wireless tag 13 is 0 for the loop antennas 25-1 to 25-4 and 25-7, as shown in FIG. It is assumed that the intensity is L for 25-8 and 25-9, and the intensity H is for the loop antenna 25-6.

  The B-CPU 14 determines, based on the distribution of signal radio waves of link information received by the nine loop antennas 25, for example, four grid areas 26 centered on the loop antenna 25-6 that has received a signal radio wave of strength H. , And the signal radio wave having the intensity L at the position farthest from the loop antenna 25-i (i = 1, 2, 3, 4, 7 in the example of FIG. 4) that received the signal radio wave having the intensity 0. Among the four grids centered on the loop antenna 25-9, the two grid areas 27 adjacent to the four grids centered on the loop antenna 25-6 that has received the signal radio wave having the strength H are Assuming that the ticket 10 is seen through the image display unit 2 of the transparent viewer 1, this range is set as the non-display position 28 of the display image.

  FIG. 5 is a flowchart showing an operation of image display processing on the image display unit 2 by the B-CPU 14 of the transparent viewer 1. This process is started by operating the power switch of the transparent viewer 1 and inputting power to the transparent viewer 1.

  In the figure, a display image is first selected (S1). In this process, for example, a thumbnail image is displayed on the image display unit 2 based on the image data file recorded on the memory card 7, and the user of the transparent viewer 1 can view the thumbnail image while the main body operation unit 21 or the touch panel is displayed. The image to be viewed is selected by the input operation from 23.

  Subsequently, the image is read (S2). In this process, the image data file of the image selected by the input operation by the user is read from the memory card 7. The image processing unit 17 performs image data decompression processing and the like, and stores the image data in a display memory (not shown).

  Next, the B-CPU 14 determines whether or not an area restriction instruction has been issued (S3). In this process, the user can manually specify a non-display area by the main body operation unit 21 or the touch panel 23.

  If there is no designation of a non-display area from the user (S3 is N), then the presence of a tag is detected (S4). This process is a process for determining whether or not the wireless tag 13 is attached to the ticket 10 which is an entity, and the intensity of the signal radio wave received by all nine loop antennas 25 is the intensity of stage 0. If there is, the B-CPU 14 determines that there is no wireless tag 13 in the ticket 10.

  When the ticket 10 does not have the wireless tag 13 (N in S4), an image is displayed at the normal position (S5). In this process, if one image is selected, that image is displayed large in the center of the image display unit 2. If there are a plurality of images, they are displayed evenly distributed over the entire surface of the image display unit 2.

  Thereafter, the B-CPU 14 determines whether there is an image contact on the touch panel (S6). This process is a process for determining whether or not the displayed image is touched by the user with the fingertip or with the dedicated pen.

  When it is determined in the above-described processing S4 that the ticket 10 has the wireless tag 13 (Y in S4), first, a non-display position is set (S7). In this process, the non-display position 28 is set by the method described with reference to FIG. 4, for example, as shown in FIG.

  Following the above, the B-CPU 14 sets the display mode (S8). In this process, the coordinates of the image display area are calculated so that the image display position does not overlap the non-display position 28 described above.

Then, the B-CPU 14 performs image display (S9). In this process, an image is displayed in the image display area where the coordinates are calculated.
FIG. 6 is a diagram illustrating two examples in which an image is displayed in a set display manner while avoiding the non-display position 28. The upper part of the figure is an example in the case of one display image, and one image 29 a is displayed above the non-display position 28 while avoiding the non-display position 28.

The lower part of the figure shows an example in the case where there are three display images. Three images 29b, 29c, and 29d are displayed around the non-display position 28 while avoiding the non-display position 28. ing.
As a result, the user of the transparent viewer 1 sees the portion of the ticket 10 that is behind the transparent viewer 1 through the non-display position 28 of FIG. 6 as shown in FIG. The shaded portion and the non-shaded portion of the transparent viewer 1 can be viewed continuously as a complete ticket 10 and one or more images selected by the user can be viewed simultaneously.

  Returning to FIG. 5 again, if there is an area restriction instruction in the determination of step S3 in FIG. 5 (S3 is Y), the display mode is set (S10). Then, an image based on the display mode is displayed (S11).

  FIG. 7 is a diagram illustrating two examples of the image display based on the result of the area restriction instruction by the user of the transparent viewer 1 and the display mode corresponding to the area restriction instruction. In this example, first, a button for selecting whether or not to issue an area restriction instruction is displayed in an appropriate display area of the transparent viewer 1, and the user 30 selects a button for performing an area restriction instruction on the main body operation unit 21 or the touch panel 23. The selected boundary line 31 is selected, an arbitrary boundary line 31 is designated, and whether or not the restricted area is above or below the boundary line 31 is inputted.

  The upper part of the figure is when the restricted area is designated below the boundary line 31, and the lower part of the figure is when the restricted area is designated above the boundary line 31. When the restricted area is designated below the boundary line 31, the B-CPU 14 displays the image 32 in the area above the designated boundary line 31, as shown in the upper part of FIG.

Further, when the restricted area is designated above the boundary line 31, the B-CPU 14 displays the image 32 in the area below the designated boundary line 31, as shown in the lower part of FIG. Do.
After any of the three image display processes of the above-described processes S5, S9, or S11, if it is determined whether or not there is an image contact on the touch panel in the process S6, if there is an image contact on the touch panel by the user ( S6 is Y), it is determined whether or not the position is moved (S12). This process is a process for determining whether or not the user has moved the fingertip that is still in contact with the image in a desired direction.

  When the user moves the fingertip in contact with the image in a desired direction (S12 is Y), the position of the movement destination is detected (S13), and a new display is displayed at the detected position. The position is set, that is, the coordinates of the display image are corrected, and the image is displayed at the set position (S15).

  If it is determined in step S12 that the user does not move the fingertip that is in contact with the image (N in S12), a predetermined menu related to the image is displayed (S16), and the user If a menu is selected (S17), an image of the selected menu is displayed (S18).

  FIG. 8 is a diagram illustrating an example of a display mode displayed on the transparent viewer 1 in accordance with the processes of the above processes S12, S16, S17, and S18. This figure shows, from right to left, a state 33-1 in which the user does not move the fingertip while still touching the image, and then a state 33-2 in which a predetermined menu related to the image is displayed. Furthermore, a state 33-3 in which the user selects a menu is shown, and a state 33-4 in which an image of the selected menu is displayed is shown.

In the above embodiment, an example is shown in which a wireless tag is attached to an entity (ticket), but a wireless tag is not necessarily attached to the entity.
FIG. 9 is a diagram illustrating a method in which a transparent viewer detects an entity without a wireless tag. The upper part of the figure shows an external perspective view (viewed from the opposite direction to FIG. 1) when detecting an entity, and the lower part of the figure shows the internal structure of the detection unit and the principle of the detection method.

  In the figure, the transparent viewer 1 ′ includes a detection unit 34 inside the gripping unit 3, and a light projection window 35 and a light reception window 36 are provided in the detection unit 34, and an infrared ray is behind the light projection window 35. An LED (liquid crystal display) 37 is arranged. The light projecting window 35 and the light receiving window 36 are arranged near both end portions on the back surface of the grip portion 3.

  A light receiving lens 38 and a line sensor 39 are arranged behind the light receiving window 36. The projection light 41 irradiated from the infrared LED 37 through the projection window 35 to the outside at a predetermined angle hits the entity 10-1 at a close position and is reflected light 42-1, or at a position away from it. The light hits a certain entity 10-2, becomes reflected light 42-2, enters the light receiving window 36, and forms an image on the line sensor 39 through the light receiving lens 38.

  The distance between the transparent viewer 1 ′ and the entity 10-1 or 10-2 is calculated based on the light receiving position that forms an image on the line sensor 39. This method is a well-known technique as a camera distance measuring device.

  In addition, when detecting the presence of an entity by this method, it is only possible to know whether or not an entity is present at a close position, and it is impossible to detect the location as described in FIG. In the example, the non-display area is not variously set according to the location of the entity, and, for example, the lower 1/3 of the entire display screen of the transparent viewer 1 'is detected when the close entity is detected. It is better to execute the process so that

  The controller 77 of the tag writer 76 communicates with the wireless tag 68 via the transmission / reception unit 91 and the antenna 92, and writes link information for associating the image data and the entity related to the image data into the wireless tag 68. . If the file name of the image data is used as the link information, the image data file can be read immediately after searching the image database based on the link information of the tag.

The link information may be a number of a predetermined number of digits, and the association with the image data file in this case will be described later.
Although not shown in particular, the feeding unit 88 includes a seal discharging device including a cutter device, a roller pair, a motor, a driving unit, a sheet position detection sensor, and the like, and the wireless tag 68 in which link information is written as described above. Is separated from the continuous seal 87, and the separated seal 67 is discharged from the seal discharge port 66 shown in FIG. 13 to the outside as shown in FIG.

  The C-CPU 72 writes the link information written in the wireless tag 68 in a predetermined data writing area of the image data stored in the memory card 81 via the image processing unit 78. Thereby, the association between the photographed image (image data, the same applies hereinafter) 62 and the ticket 61 is completed. That is, the ticket 61 as an entity and the photograph 62 are linked through the seal 67 to which the wireless tag 68 is attached and the link information written in the wireless tag 68.

  As described above, according to the camera 63 of the fourth embodiment, the wireless tag attached sticker can be attached to an entity such as a ticket, admission ticket stub, admission ticket, or catalog. Since the link information that associates the image data of a photograph taken of a landscape, person, or observation object related to acquisition is output, the photographer can attach the output from the camera (tagged sticker) to the entity. The image data can be easily retrieved from the entity by simply reading the link information at a later date. In addition, since the information of the wireless tag can be easily detected without contact, it is extremely convenient and convenient.

  FIG. 15 is a diagram showing the data structure of an image data file recorded on the memory card 81. In the example shown in the figure, three types of files are stored in a folder 001TAMAB created in the root directory DCIM.

  An image data file is stored at the top of the file area. In the example shown in the figure, the image data file P701001. JPG, P701002. JPG, P7010003. JPG,... Are stored.

  In the middle of the file area, post-record audio data whose extension is indicated by WAV is stored. In the example shown in the figure, the audio data file P701001. WAV, P7010005. WAB,... Are stored. Audio data file P701001. WAV stores the image data file P701001. The audio data file P7010005. WAV stores the image data file P7010005. It corresponds to JPG.

  Further, behind the file area, a text data file as a comment or memorandum relating to an image is stored. In the example shown in the figure, the text data file P701001. TXT,... Are stored. Text data file P701001. TXT is an image data file P701001. It corresponds to JPG.

That is, audio data files, audio data files, and text data files correspond to each other with the same file name excluding the extension.
The image data file has an accompanying data area 93 called a maker note. This supplementary data area 93 is an area that can be used arbitrarily by the camera manufacturer. In the camera 63 of this example, as shown in the figure, the link flag, link information, shooting date and time, shooting location, photographer, and genre are displayed. Each data area is provided.

  Here, in the link information data area, number data composed of serial numbers such as “1”, “2”, “3”,. This number data is, for example, link information written in the wireless tag 68 of the seal 67 shown in FIGS.

  Thereby, for example, the link information “2” is stored in the ticket 61 to which the seal 67 with the wireless tag 68 written with the link information “2” is attached and the link information data area of the incidental data area 93. Image data file P701002. JPG is associated.

Further, for example, image data file P7010003. In which “0” is stored in the link information data area. JPG indicates that there is no entity associated with this photo.
In the link flag data area of the incidental data area 93, “1” is stored for all image data files in which link information is stored in the link information data area. As a result, it is possible to easily check whether the image data is related to the entity.

  In addition, although the entity has been described by replacing it with a ticket, the present invention is not limited to this. For example, as described above, a chopstick bag with the name of a disposable chopstick after use, a small box of service match, etc. Anything can be used as long as it becomes a memorial that can be stored on a scrapbook or an appropriate sheet of about A4 size (a service match or the like is applied after being flattened).

Although the link information has been described as a one-digit number, it goes without saying that it may be a two-digit number or more.
When the ticket 61 associated with the image data file by the link information is viewed through the transparent viewer 1 shown in FIG. 1, the transmission / reception unit 18 of the transparent viewer 1 passes through the antenna 25. The link information of the wireless tag 68 of the ticket 61 is read, and based on this link information, the image data file related to the ticket 61 is read from the memory card 7 (the memory card 81 taken out from the camera 63 and attached to the transparent viewer 1). Automatically read out and the image of the read image data file is displayed on the image display unit 2 of the transparent viewer 1 in the display mode shown in FIG.
