As a whole, it is used like a stand and can be moved to a free place.

FIG. 1 is a block diagram showing a specific example of the image display apparatus of the present invention.
The image display apparatus shown in FIG. 1 has a configuration in which a display plate 1 that displays an image is supported by a support frame 3. The display board 1 consists of transparent materials, such as an acrylic resin, for example. A screen 5 is provided on the lower surface. The screen 5 may be a translucent film, or may be a portion obtained by processing the back surface of the display plate 1 into a frosted glass shape. Here, an image projected from a projector described later forms an image. Since the display panel 1 is made of a transparent body, the image formed on the screen 5 can be seen from obliquely above.

  That is, as shown in the figure, the support frame 3 supports the surface of the display panel 1 having the screen 5 inclined with respect to the floor surface when the image display device is set upright on the horizontal floor surface. ing. A projector 11 is fixed to the support frame 3 together with the display plate 1, and projects an image on the screen 5. With such a structure, the external light is reflected by the surface of the display panel 1 when it is slightly away from the display panel 1, so that it is difficult to see the image. Therefore, in order to see this screen in a standing state, there is an effect of drawing a passerby to the vicinity of the device.

FIG. 2 is an enlarged perspective view of the image display device.
The storage unit 10 stores a projector 11 that emits a projection beam. The projection beam emitted from the projector 11 is reflected by the portion of the window 15 provided in the storage unit 10, turns upward, passes through the window 15, and is projected onto the screen 5. The support frame 3 is composed of an aluminum pipe or the like. The support frame 3 includes an inclined portion 3A, a vertical portion 3B, a horizontal portion 3C, an arm 3D, and a mount 3F. Four arms 3D protrude from the side surface of the inclined portion 3A, and these support the display board 1 with screws. The horizontal bar 3E is provided to reinforce the support frame 3. The gantry 3F is for fixing and supporting the storage unit 10 to the support frame 3.

  Returning to FIG. 1 again, the projector 11 is provided with a circuit block shown in FIG. That is, a connector 31, a hard disk 32, an image display control means 33, a power supply circuit 34, a liquid crystal driving unit 35, and a remote controller interface 36 are provided. The connector 31 is detachably mounted with a storage medium 20, for example, a memory card incorporating a semiconductor storage device here. The storage medium 20 stores image data 23 obtained by editing an image to be displayed on the display board 1.

  The hard disk 32 stores the image data 23 in the storage medium 20 as necessary, or stores various parameters and control programs. When the amount of data to be stored in the projector 11 is small, a low-capacity memory such as a flash memory may be mounted instead of the hard disk 32. The image display control unit 33 has a function of reading the image data 23 from the storage medium 20 attached to the connector 31, generating an image to be displayed on the display panel 1, and supplying the image to the liquid crystal driving unit 35. The image display control means 33 is composed of a computer program or the like.

  The liquid crystal driving unit 35 is a part incorporated in the well-known control of the projection image of a liquid crystal projector, and has a function of displaying the image data 23 on a transmissive liquid crystal panel irradiated with a light source. Since this part is already known, detailed description is omitted. The power supply circuit 34 is for driving the apparatus, and is composed of a general commercial power supply or a battery. The remote controller interface 36 is prepared for an administrator to input a device on / off or image data reproduction instruction using the remote controller. In the example of FIG. 1, the administrator can hold the remote controller 25 to approach the apparatus and remotely operate the projector 11 stored in the storage box 10.

  As shown in FIG. 2, the projector 11 housed in the housing unit 10 is provided with a memory slot 12, and the connector 31 shown in FIG. 1 is housed therein. The storage medium 20 is attached to the connector 31. In addition, since this image display apparatus is arrange | positioned at the shop front etc. of a store, it is necessary to prevent careless operation of the projector 11 by an outsider. For this reason, a lid 17 with a key is provided in the storage box 10, and the lid 17 is opened and closed to detach the storage medium 20. The image display device automatically displays the stored image data on the display board 1 by mounting the storage medium 20. If the storage medium 20 is replaced, another image is displayed. Since the operation is very simple and there is no connection operation to a network or the like, management is easy. Therefore, for example, images can be freely displayed in separate menus in the morning, afternoon, and night. Further, the image data stored in the storage medium 20, so-called content, may be created by the owner of the store, or may be produced and supplied by a specialized management company.

FIG. 3 is a flowchart showing a specific operation of the image display apparatus.
First, in step S1, the image display apparatus is powered on, and the start switch of the projector 11 is turned on. In step S2, a lamp (not shown) of the projector 11 is turned on. Next, simultaneously with the lighting of the lamp, the following image data preparation process is executed. In step S <b> 3, a data file of image data stored in the storage medium 20 is read by the image display control means 33. In step S4, display image data included in the data file is acquired. The data file may be generated by a general application program for presentation using a computer.

  Image data to be supplied to the liquid crystal drive unit 35 is obtained by the image display control means 33 having the same function as the application program. The converted image data is, for example, data in a format obtained by photographing with a digital camera. The displayed image may be either a still image or a moving image. This data is stored in the buffer memory in step S6. For example, all the image data can be stored in the display order in the hard disk 32 shown in FIG. Further, it may be stored in an empty area of the storage medium 20. The storage medium 20 may store data in a format that can be immediately displayed from the beginning. At this time, the processing from step S3 to step S6 surrounded by the broken line frame in FIG. 3 is unnecessary, and the process can proceed directly from step S2 to step S7.

  In step S7, the image display control means 33 reads the data stored in the buffer memory, for example, one image at a time. In step S8, the data is transferred to the liquid crystal drive unit 35 of the projector 11. Thereby, a projection beam is output by a well-known function of the liquid crystal projector, and this is imaged on the screen 5 of the display panel 1 shown in FIG. In step S9, it is determined whether the read data is the last one. If it is not the last one, the process returns to step S7 to read the next data. That is, the image display is performed in order for all the image data stored in the buffer memory by repeating the processes of step S7, step S8, and step S9.

  The display control by the image display control means 33 may be the same as the well-known function of the slide show of the presentation program. When the display process is completed for all the image data in the buffer memory, the process proceeds to step S10. In step S10, the read control operation is initialized. And it returns to the state immediately before step S7. In step S11, it is determined whether all the processes have been completed. When ending the operation of the projector, the process ends here, and then the power is turned off. When the display operation of the projector is continued, the process returns to step S7, and data is read again in order from the beginning. That is, as long as there is no end instruction, the operation of repeatedly displaying the same image data on the display board 1 is continued. By such control, the image data stored in the storage medium 20 for a predetermined time is continuously displayed on the display panel 1.

  According to the above configuration, if the storage medium 20 stores, for example, a guide display screen such as a restaurant menu or today's recommendation including still images and moving images, the storage medium is attached to the apparatus, The guidance display screen can be automatically projected and displayed on the screen simply by inserting. Further, for example, when differentiating between a breakfast menu, a lunch menu, a dinner menu, and the like, it is possible to switch each time by simply replacing the storage medium, and there is an effect that the administrator is not burdened.

  In the above example, new image data can be freely displayed by attaching the storage medium 20 to the connector 31 of the projector 11 and exchanging it. However, a series of operations for opening the lid 17 of the storage unit 10 shown in FIG. In the image display device of the second embodiment, a storage device such as a hard disk for storing image data is prepared in the projector 11 and a non-contact interface such as a well-known infrared interface is used. Is written. In addition, various existing data transfer interfaces such as Bluetooth can be used as the non-contact interface.

FIG. 4 is an explanatory diagram illustrating the contents of the internal circuit and the accessory device of the image display apparatus according to the second embodiment.
FIG. 4A shows a transmitter 40 for transferring image data to the projector 11 using a non-contact interface. FIG. 2B is an internal circuit block diagram of the projector 11. As shown in FIG. 4A, the transmitter 40 is provided with a memory slot 41 into which the storage medium 20 is attached. The storage medium 20 is the same as that described in the first embodiment, and stores display image data. The transmitter 40 is provided with a transmission button 42, an infrared transmission unit 43, a data transfer control device 44, and an infrared interface 47.

  When the transmission button 42 is pressed, infrared rays are transmitted from the infrared transmission unit 43. Through this interface, the image data stored in the storage medium 20 is transmitted to the projector 11. An infrared interface 45 is provided on the projector side. The function of the infrared interface is well known and will not be described in detail. However, image data is transferred to the hard disk 32 and stored by communication with the transmitter 40. The image data 23 can be completely rewritten each time the transmitter 40 is operated. The operation of projecting and displaying the image data 23 stored in the hard disk 32 by the projector 11 is exactly the same as in the first embodiment. Note that the transmitter 40 shown in FIG. 4A is preferably integrated with the remote controller 25 for device control described in FIG. That is, a space as shown by a broken line is provided on the upper surface of the transmitter 40 in FIG. 4A, and a control button for a remote controller may be arranged there.

FIG. 5 is an explanatory diagram illustrating a configuration of the image display apparatus according to the third embodiment.
This image display device will be described in comparison with the image display device shown in FIG. In this image display device, a schedule management data memory 46 is provided in the image display device of FIG. The touch panel 50 is provided on the display panel 1 of the image display device. A signal for operating the touch panel 50 is received by the image display device via the touch panel interface 56. Of course, the following control may be performed by displaying an image as shown in the touch panel 50 on the remote controller described in the second embodiment.

  On the control screen operated by the touch panel 50 shown in FIG. 5, the display time 51 of the image data and the file name 52 of the image data can be input. An arbitrary time may be entered as a number at the display time 51. The file name 52 is selected from a drop-down list. When a predetermined file name is selected, for example, an AAA file for breakfast menu until 11 am, a BBB file for lunch menu from 11 am to 3 pm, and a dinner menu after 6 pm Settings such as CCC files can be made. Pressing the button 53 confirms the setting. The button 54 is for initializing and canceling input data. When the button 53 is pressed, the set schedule information is stored in the schedule management data memory 46.

  FIG. 5B shows an example of schedule information stored in the schedule management data memory 46. As illustrated, a display time 61 and an image data file name 62 set on the touch panel 50 are recorded. The image display control means 33 can sequentially read out the image data 23 from the hard disk 32 according to the schedule information, and can automatically project and display the image data 23 on the display board 1 (FIG. 1) at a predetermined timing. The schedule information can be in any format other than the example shown in the figure. For example, if there are 40 pieces of image data displayed in 15 seconds per page, the display of this set of image data is completed in 10 minutes. After repeating this cycle for 2 hours, another set of image data is selected and the same processing is repeated. In this way, automatic image projection display control can be performed using information such as read image data, the reading order, display time, and the number of display repetitions as schedule information.

FIG. 6 is an explanatory diagram showing an example of information stored in the storage medium.
In the above embodiment, the schedule for displaying the image data 23 stored in the storage medium 20 is input using an operation means such as a touch panel. However, for example, a service company that edits image data and provides it to a user can distinguish image data for a breakfast menu, lunch menu, and dinner menu. Further, it is possible to receive a notification of the display schedule of these image data from the user. Therefore, schedule data can be created in advance by the service company.

  In FIG. 6A, schedule information 59 is stored in the storage medium 20 along with the image data 23. The contents are as described with reference to FIG. The image display control means 33 (FIG. 5) reads the schedule information 59, reads out the corresponding image data 23 from the storage medium 20 in order, and performs projection display control. As a result, the user of the image data 23 can start using the apparatus by simply mounting the storage medium 20 on the projector and without inputting a schedule.

  In the example of FIG. 6B, the management information 60 is stored in the storage medium 20. This management information includes, as shown in (c) of the figure, each piece of image data stored in the storage medium 20 with identification information 65 for distinguishing the image display device to which the storage medium is attached from other image display devices. 23 is associated with the data file name 66 of FIG. For example, these image data files are encrypted so that they cannot be read as they are. When the identification information is input after the apparatus is activated, the encryption of the image data file for the apparatus is decrypted and read. Thus, use of unrelated image data can be prevented. In addition, by sharing data, for example, a storage medium for a department store containing a large number of tenants can be produced with the same contents all at once, and the cost for producing the storage medium can be reduced. Also, when providing a service that provides a wide variety of image data, the image data necessary for each image display device can be delivered individually without fail.

FIG. 7 is a block diagram of an image display apparatus according to the fifth embodiment.
The embodiment in this figure is an example of an image display apparatus that automatically mounts and displays an image by attaching the storage medium 20 storing both schedule information 59 and management information 60 in addition to the image data 23. Show. This storage medium 20 is distributed to a large number of tenants in one department store, for example. All tenants are distributed with the same storage medium 20.

  The image display device used by each tenant is provided with an identification information memory 67 for storing identification information for identifying the device. The identification information memory 67 is a non-volatile memory. Once the identification information is recorded, the information is not lost even when the apparatus is turned off. Identification information is input using the touch panel 50 of the display board 1, for example. Identification information is input to the frame 72 using the numeric keypad 71 of the touch panel 50. When the cancel button 74 is pressed, the identification information can be entered again. When the set button 73 is pressed, the touch panel interface 56 acquires the input identification information and writes it in the identification information memory 67. Thereafter, the input identification information is used no matter how many times the apparatus is activated. Based on this identification information, one of the plurality of image data stored in the storage medium 20 is selected and read. The image data selection unit 68 reads the management information 60 and selects image data corresponding to the identification information. The functions of the other blocks are almost the same as those of the embodiment described above.

FIG. 8 is a flowchart showing a specific operation of the apparatus of FIG.
In this flowchart, the operation of the computer program by the image data selection unit 68 and the image display control unit 33 of the projector 11 will be mainly described. First, in step S21, when the storage medium 20 is attached to the projector 11, the image data selection means 68 detects the attachment state. Then, the identification information memory 67 is accessed to determine whether the identification information has already been registered (step S22). If the identification information is not registered, identification information registration processing is requested in steps S23 and S24. If the identification information is registered, the process proceeds directly from step S22 to step S25.

  In step S23, the image data selection means 68 requests input of identification information using the touch panel 72 or the like as described in FIG. When the identification information is input, the image data selection unit 68 stores the identification information in the identification information memory 67 and completes the registration process (step S24). The identification information input operation may be performed by a user or administrator of the image display apparatus, but may be performed by, for example, a service person who delivers or maintains the apparatus. Further, it may be already registered as device-specific information when the device is delivered.

  The image data selection means 68 reads the identification information from the identification information memory 67, reads the management information 60 of the storage medium 20 (step S25), and selects the image data corresponding to the identification information (step S26). For example, the image data file list is temporarily stored. Subsequently, the schedule information 59 is read out, and all the image data to be read out are selected (step S27). Of the image data that can be read in correspondence with the identification information, only the image data group specified by the schedule information 59 may be selected for display. Receiving the notification from the image data selection means 68, the image display control means 33 reads the corresponding image data from the selected image data group one by one in order from the storage medium 20 (step S28), and drives the liquid crystal. The data is transferred to the unit 35 (step S29). The operations from step S28 to step S30 are repeated until all the selected image data is read out.

  After all the image data has been read, the read control is initialized (step S31). That is, the read pointer is initialized. When the operation of the apparatus is continued, the process returns from step S32 to step S27, and the display operation is repeated according to the schedule information. That is, the same image data group can be repeatedly displayed or replaced with another image data group. Even in this case, since the schedule information 59 is stored in the storage medium 20 in advance, there is an effect that the user does not need to set a complicated schedule in the projector.

  In addition, the computer program by each said means may be comprised combining each independent program module, and may be comprised by the program which integrated the whole. All or part of the process controlled by the computer program may be configured by hardware having equivalent functions. The computer program for realizing the present invention can be recorded on a computer-readable recording medium such as a CD-ROM and installed in any information processing apparatus for use. It can also be downloaded and used in the memory of any computer through the network.
