Description

  The present invention relates to a captured image display method and a display processing device, and more particularly to a technique for displaying a captured image of a digital camera on an external display device.

In recent years, as one function of a digital camera, development of a network function that can connect the digital camera to other electronic devices such as a personal computer and a monitor is progressing. In particular, if a so-called wireless LAN system such as IEEE802.11 is used, it is possible to connect to other devices over the network without conventional wiring. In addition, there is a merit that the memory capacity in the digital camera can be reduced by adopting a method of transmitting a photographed image to the image file server every time photographing is performed. As a form of using the network function of such a digital camera, a method of using a captured image by transferring it to an external display device such as a liquid crystal projector can be considered. Here, a technique for synchronizing display contents of a screen on a presentation computer with the screens of a plurality of browsing computers is known (see, for example, Patent Document 1).
JP 2000-66968 A

  However, at present, the display content on the built-in screen of the digital camera is merely transferred to the external display device and synchronized as it is by the NTSC method or the like, and thus the content that should not be displayed on the external display device is displayed synchronously. End up. In particular, in a situation where a photographed image is displayed in a presentation or a meeting, content that is not desired by the presenter, such as screen content during operation of the digital camera, is displayed to the outside.

  The present invention has been made in view of such circumstances, and an object of the present invention is to enhance convenience related to external display of an image photographed by a digital camera.

  One embodiment of the present invention is a captured image display method. This method includes a step of acquiring control information indicating a display form of a captured image to be displayed on the screen of the imaging device via a network, and a display content on the screen of the imaging device when the content of the control information satisfies a predetermined determination criterion. And a step of confirming that the display content on the screen of the external display device should be synchronized, and a step of displaying the captured image on the screen of the external display device with the confirmation as a trigger.

  According to this aspect, when the screen display content is synchronized between the imaging device and the external display device, even if the display content of the imaging device is changed, there is content to be synchronized until the display form becomes a predetermined form. Not confirmed. Therefore, only the contents suitable for display on the external display device can be synchronized. In addition, contents that do not need to be displayed to the outside, such as a working screen in the imaging device, are not displayed on the external display device.

  Another aspect of the present invention is a display processing apparatus. This apparatus includes an instruction acquisition unit that acquires control information indicating a display form of a captured image to be displayed on the screen of the imaging device via a network, an image acquisition unit that acquires a captured image from the imaging device via the network, and control information. A determination unit that determines whether or not the display form to be displayed is a predetermined form in which the display content on the screen of the imaging apparatus should be synchronized with a screen provided outside the imaging apparatus; A display processing unit that displays a captured image in a form in which display content on the screen of the imaging apparatus is synchronized with a screen provided outside.

  Here, the display processing device may be configured by combining a display device with an image file server that acquires a captured image from the imaging device and stores the captured image. In this case, the image file server may directly control the display device via a monitor cable connection, or the display device and the image file server are connected to the network to transmit a captured image and control information as a whole. It may function as a display processing device. In these cases, each of the instruction acquisition unit, the image acquisition unit, the determination unit, and the display processing unit may be provided in either the image file server or the display device, or provided in both the image file server and the display device. Also good. Furthermore, a configuration in which a part of each function included in the display processing device is provided to the imaging device may be employed.

  Also in this aspect, even if the display content of the imaging device is changed, the content to be synchronized with the external display device is not determined until the display form becomes a predetermined form. Therefore, only content suitable for display on the external display device can be synchronized, and content that does not need to be displayed externally, such as a screen during work in the imaging device, is not displayed on the external display device.

  It should be noted that any combination of the above-described components, and the components and expressions of the present invention are mutually replaced between a method, apparatus, system, computer program, recording medium storing the program, data structure, etc. This is effective as an embodiment of the present invention.

  ADVANTAGE OF THE INVENTION According to this invention, the convenience regarding the external display of the image image | photographed with the imaging device can be improved.

(First embodiment)
The image display system according to the present embodiment includes an imaging device and a display processing device. The imaging device transfers an image obtained by shooting to the display processing device, and the display processing device stores the image. Both the imaging device and the display processing device have a display screen, and the screen display content of the imaging device can be displayed synchronously on the screen of the display processing device. At this time, when displaying multiple thumbnails of multiple captured images on the screen of the imaging device, the display is not synchronized, and the same image is displayed synchronously on the display processing device screen only when the captured image is displayed on the imaging device in full screen. Let As a result, contents that you do not want to display on the external screen, such as display contents during operation such as image selection in the imaging device, and unconfirmed information are not displayed on the display processing device, and only the contents that are suitable for external screen display are synchronized. Can be made.

  FIG. 1 shows a basic network configuration of the image display system 10. The imaging device 12 is a digital camera having a network communication function, and the display processing device 24 is a computer having a network communication function. The display processing device 24 has both a function as an image file server and a function as a display device. The imaging device 12 and the display processing device 24 are network-connected in an ad hoc mode using a wireless LAN system such as IEEE802.11. The imaging device 12 transfers an image obtained by photographing to the display processing device 24, and the display processing device 24 stores it. The imaging device 12 sends an image transmission request to the display processing device 24 when reproducing the image, and the display processing device 24 transfers the requested image to the imaging device 12. The imaging device 12 reproduces the image received from the display processing device 24 and displays it on the screen. Here, an image display mode is assumed to be a full screen display in which one image is displayed in a full screen size and a multi display in which thumbnails of a plurality of images are arranged and displayed in the screen.

  Each configuration of the imaging device 12 and the display processing device 24 can be realized in hardware by a CPU, a memory, a communication module, an LCD, and other LSIs, and in software terms, an image processing function and data transmission / reception loaded in the memory. Realized by a functional program. Those skilled in the art will understand that the functional blocks described in FIG. 2 and subsequent figures can be realized in various forms by hardware alone, software alone, or a combination and combination thereof.

  FIG. 2 is a functional block diagram showing the configuration of the display processing device 24. The display processing device 24 includes a communication unit 30, an instruction acquisition unit 32, an image acquisition unit 34, a determination unit 36, an image storage unit 38, a display processing unit 40, and an image transmission unit 42. Each unit transmits / receives data to / from the outside, in particular, the imaging device 12 via the communication unit 30.

  The image acquisition unit 34 acquires the captured image from the imaging device 12 and stores the acquired image in the image storage unit 38. The instruction acquisition unit 32 acquires, from the imaging device 12, control information indicating the display form of the captured image to be displayed on the screen of the imaging device 12 when the user instructs the imaging device 12 to reproduce the captured image. The control information includes an event notification indicating the request contents, and the file name of the photographed image and the range of the data area in the file as its arguments. For example, the argument indicates a range of how many bytes of data should be transmitted from the top of the image file. In a region near the header in the image file, a so-called thumbnail image obtained by reducing the size of the image is stored.

  If the control information indicates the number of bytes in which the entire image file is included, the full screen display is suggested as the display form in the imaging device 12. If the control information indicates the number of bytes in which only a part of the image file is included, thumbnail display is suggested as a display form in the imaging device 12. The image transmission unit 42 reads the data area indicated by the control information out of the captured image indicated by the control information from the image storage unit 38 and transmits it to the imaging device 12.

  The determination unit 36 determines whether or not the display form indicated by the control information is a predetermined form in which the display content on the screen of the imaging device 12 should be synchronized with the display processing device 24. The criterion for this determination differs depending on whether the imaging device 12 is in the shooting mode or the playback mode. In the case of the shooting mode, when the control information suggests a full-screen display of a shot image that is to be confirmed when shooting content is confirmed, it is determined that the display mode is a mode to be synchronized. In the case of the playback mode, when full-screen playback display is suggested by the control information, it is determined that the display mode is a mode to be synchronized. That is, it is determined whether full screen display is suggested based on an instruction to specify a data area in the control information. When a display form other than these is suggested in the control information, the determination unit 36 determines that the timing to be synchronized has not been determined.

  When it is determined that the display form indicated by the control information is a form to be synchronized, the display processing unit 40 reads the captured image indicated by the control information from the image storage unit 38 and displays it on the screen. As a result, the content displayed on the full screen on the screen of the imaging device 12 can be synchronously displayed on the screen of the display processing device 24.

  FIG. 3 shows a communication process with the display processing apparatus 24 and an operation mode determination process immediately after the imaging apparatus 12 is powered on. When the power of the imaging device 12 is turned on (S10), the imaging device 12 transmits a connection request to the display processing device 24 (S12), and when the display processing device 24 responds to this (S14), the connection is established. When the shooting mode is selected by the user as the operation mode of the imaging device 12 (“shooting mode” in S16), a shooting sequence is started (S18). When the playback mode is selected by the user (“playback mode” in S16), the playback sequence is started (S20). The shooting sequence will be described with reference to FIG. 4, and the reproduction sequence will be described with reference to FIG.

  FIG. 4 shows a photographing sequence in S18 of FIG. When the user presses the shutter button of the imaging device 12 (S30), the imaging device 12 processes the generation of the captured image (S32), and while the user holds down the shutter button of the imaging device 12 (S34). The imaging device 12 displays the captured postview in full screen (S36). When the user cancels the pressing of the shutter button and the shooting is confirmed with the post-view display image by selecting the OK button or the like (S38Y), the imaging device 12 transmits the captured image together with the control information to the display processing device 24. (S40). The display processing device 24 that has received the captured image stores it according to the control information (S42). The control information includes an event notification for instructing the storage of the captured image. Based on this control information, the display processing device 24 confirms the display form on the imaging device 12 when the captured content is confirmed. It is determined that the display is a full screen display (S44), and the captured image is displayed synchronously (S46). On the other hand, in S38, when the user does not confirm the shooting with the post-view display image by selecting the cancel button or the like (S38N), the processing after S40 is skipped and the shooting is terminated.

  FIG. 5 shows the playback sequence in S20 of FIG. When the user instructs thumbnail display (S50), the imaging device 12 transmits control information to the display processing device 24 (S52), and the display processing device 24 returns a thumbnail image based on the control information (S54). The imaging device 12 receives and displays (S56). The display processing device 24 determines whether an image to be transmitted to the imaging device 12 is also displayed on the display processing device 24 synchronously (S58). Here, since the thumbnail display is suggested in the control information, the display content of the imaging device 12 is not synchronized. If an instruction to multi-display a plurality of thumbnail images is given in S50, the processes in S52 and S54 are repeated for the number of images.

  When the user selects one of the thumbnail-displayed images and instructs full screen display (S60), the imaging device 12 transmits control information to the display processing device 24 (S62), and the display processing device 24 uses the control information. Based on this, the photographed image is returned (S64), and this is received by the imaging device 12 and displayed in full screen (S66). The display processing device 24 determines whether to display the image to be transmitted to the imaging device 12 also on the display processing device 24 (S68). Here, since full-screen display is suggested in the control information, the captured image to be displayed on the imaging device 12 is displayed synchronously (S70).

  FIG. 6 shows the data structure of an image file stored in the image storage unit 38. The image file 80 mainly includes a header area 82, a thumbnail area 84, and an actual data area 86. The header area 82 stores data such as data size, data compression rate, and shooting information, and the thumbnail area 84 stores thumbnails of the shot images. The actual data that is the captured image itself is stored in the actual data area 86. Here, when the request data area indicated in the control information indicates a range from the first byte of the image file 80 to the middle byte including the header area 82 and the thumbnail area 84 as shown in FIG. It can be seen that this indicates a transmission request. If the requested data area shown in the control information is a range including all of the header area 82, thumbnail area 84, and actual data area 86 from the first byte of the image file 80 as shown in (b), this control information Can be requested to send the entire image, suggesting full screen display.

  FIG. 7 shows a detailed process of determination processing in the playback mode in S58 and S68 of FIG. A value indicating the actual data area 86 is written in the value I (S80), and a value indicating the thumbnail area 84 is written in the value T (S82). In the value R, the request data area is written (S84). When the range of the requested data area indicated by the value R includes the range of the actual data area 86 indicated by the value I (S86Y), it is determined that the control information indicates full screen display (S88), and the remaining steps To skip. A thumbnail in which the range of the requested data area indicated by the value R does not include the range of the actual data area 86 indicated by the value I (S86N), and the range of the requested data area indicated by the value R is indicated by the value T When the range of the region 84 is included (S90Y), it is determined that the control information indicates thumbnail display (S92), and the remaining steps are skipped. When the range of the requested data area indicated by the value R does not include the range of the thumbnail area 84 indicated by the value T (S90N), it is determined that the control information indicates other instructions or other display forms (S94).

  As described above, the imaging device 12 sends control information related to image storage or image reproduction to the display processing device 24, but the control information does not directly indicate whether or not display contents should be synchronized. Therefore, the image display system 10 of the present embodiment is characterized in that it is determined whether or not to synchronize by referring to information that is not originally related to display synchronization. Accordingly, the user can appropriately perform display synchronization without performing a special operation related to display synchronization on the imaging device 12.

(Second Embodiment)
The image display system 10 of the present embodiment differs from the first embodiment in that the display processing device 24 of the first embodiment is configured by a combination of an image file server and a liquid crystal projector. Hereinafter, the difference from the first embodiment will be mainly described.

  FIG. 8 shows a basic network configuration of the image display system 10. The image display system 10 includes an imaging device 12, an access point 14, a plurality of liquid crystal projectors 18, and an image file server 25. The plurality of liquid crystal projectors 18, the image file server 25, and the access point 14 are connected via the IP network 16. The access point 14 is a base station for wireless network communication, and the imaging device 12 is connected to the IP network 16 via the access point 14. The combination of the liquid crystal projector 18 and the image file server 25 has a configuration corresponding to the display processing device 24 in the first embodiment. The imaging device 12 stores the captured image in the image file server 25 via the access point 14 and causes the captured image to be displayed synchronously on the imaging device 12 and any of the plurality of liquid crystal projectors 18.

  FIG. 9 is a functional block diagram showing the configuration of the image file server 25. The image file server 25 includes a communication unit 50, an instruction acquisition unit 52, an image acquisition unit 54, an image transmission unit 56, an image storage unit 58, and a display processing unit 60. These units have substantially the same functions as the communication unit 30, the instruction acquisition unit 32, the image acquisition unit 34, the image transmission unit 42, the image storage unit 38, and the display processing unit 40 to which the same names are given in FIG. . However, the instruction acquisition unit 52 sends the control information acquired from the imaging device 12 to the display processing unit 60, and the display processing unit 60 transfers this to the liquid crystal projector 18 via the IP network 16. The display processing unit 60 further reads out a captured image to be displayed on the external screen from the image storage unit 58 and transmits it to the liquid crystal projector 18 via the IP network 16.

  FIG. 10 is a functional block diagram showing the configuration of the liquid crystal projector 18. The liquid crystal projector 18 includes a communication unit 70, an instruction acquisition unit 72, an image acquisition unit 74, a determination unit 76, and a display processing unit 78. Each of these units has substantially the same function as each of the communication unit 30, the instruction acquisition unit 32, the image acquisition unit 34, the determination unit 36, and the display processing unit 40 to which the same name is given in FIG. However, the instruction acquisition unit 72 acquires control information from the image file server 25, and the image acquisition unit 74 acquires a captured image to be displayed synchronously from the image file server 25. Based on the control information, the determination unit 76 determines whether the captured image should be displayed on the screen in synchronization. If it is determined to synchronize, the determination unit 76 instructs the image acquisition unit 74 to acquire an image. The image acquisition unit 74 acquires an image to be synchronized from the image file server 25 based on an instruction from the determination unit 76. The display processing unit 78 causes the image acquired by the image acquisition unit 74 to be displayed on the screen when the determination unit 76 determines to synchronize.

  Also with the above configuration, only images suitable for external display can be synchronized as in the first embodiment. Hereinafter, the operation of each component in the image display system 10 of the second embodiment will be described.

  FIG. 11 shows a communication process and an operation mode determination process with the image file server 25 and the liquid crystal projector 18 immediately after the imaging apparatus 12 according to the second embodiment is powered on. When the imaging device 12 is turned on (S100), the imaging device 12 transmits a connection request to the image file server 25 (S102), and the image file server 25 returns a list of a plurality of liquid crystal projectors 18 as a response thereto. (S104) The connection between the imaging device 12 and the image file server 25 is established, and the imaging device 12 displays a list of the plurality of liquid crystal projectors 18 (S106). When the user selects one from the list (S108), the imaging device 12 transmits the selection information to the image file server 25 (S110), and the image file server 25 transmits a connection request to the liquid crystal projector 18 indicated by the selection information. (S112). In response to this, when the connection is established in response to the liquid crystal projector 18 (S114), the image file server 25 responds to the imaging device 12 (S116). After the imaging device 12 receives the response from the image file server 25, when the shooting mode is selected by the user as the operation mode in the imaging device 12 (“shooting mode” in S118), the shooting sequence is started (S120). . When the playback mode is selected by the user (“playback mode” in S118), the playback sequence is started (S122). The shooting sequence will be described with reference to FIG. 12, and the reproduction sequence will be described with reference to FIG.

  FIG. 12 shows a shooting sequence in S120 of FIG. When the user presses the shutter button of the imaging device 12 (S130), the imaging device 12 processes the generation of the captured image (S132), and while the user keeps pressing the shutter button (S134), the imaging device 12 Is displayed (S136). When the user confirms the shooting with the post-view image (S138Y), the imaging device 12 transmits the captured image together with the control information to the image file server 25 (S140). The image file server 25 that has received the captured image stores it (S142). In S138, when the user does not confirm shooting with the post-view image (S138N), S140 and the subsequent steps are skipped and the shooting is terminated.

  The image file server 25 stores the captured image in S142, and then transmits control information to the liquid crystal projector 18 (S144). The liquid crystal projector 18 determines whether to display synchronously based on the control information (S146). Here, since it is determined that the full-screen display for confirmation at the time of photographing confirmation is suggested, the liquid crystal projector 18 requests the image file server 25 to transmit the photographed image (S148) and responds to this. Then, the image file server 25 transmits the captured image to the liquid crystal projector 18 (S150), and the liquid crystal projector 18 displays it on the screen (S152).

  FIG. 13 shows the playback sequence in S122 of FIG. When the user instructs thumbnail display (S160), the imaging device 12 transmits control information to the image file server 25 (S162), and the image file server 25 transfers the control information to the liquid crystal projector 18 (S164). It is determined whether or not the image displayed on the imaging device 12 is to be displayed synchronously on the liquid crystal projector 18 (S166). Here, since the thumbnail display is suggested in the control information, the liquid crystal projector 18 does not synchronize the display content of the imaging device 12. The image file server 25 returns a thumbnail image to the imaging device 12 based on the control information (S168), and the imaging device 12 receives and displays it (S170). If an instruction to multi-display a plurality of thumbnail images is issued in S160, the processing from S162 to S168 is repeated for the number of images.

  When the user selects one of the thumbnail-displayed images and instructs full screen display (S172), the imaging device 12 transmits control information to the image file server 25 (S174). The image is transferred to the projector 18 (S176), and the liquid crystal projector 18 determines whether or not the image displayed on the imaging device 12 is also displayed synchronously on the liquid crystal projector 18 (S180). Here, since full-screen display is suggested in the control information, the image file server 25 is requested to transmit the captured image displayed on the imaging device 12 (S184), and the image file server 25 captures the image in response to this. The image is transmitted to the liquid crystal projector 18 (S186), and the liquid crystal projector 18 displays the image synchronously (S188). On the other hand, the image file server 25 returns the captured image to the imaging device 12 based on the control information (S178), and the imaging device 12 receives this and displays it on the full screen (S182).

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to the combination of each component and each processing process, and such modifications are also within the scope of the present invention. .

  In the second embodiment, the configuration in which the liquid crystal projector 18 determines whether to synchronize the image with the liquid crystal projector 18 has been described. In the modification, the image file server 25 may perform the determination. In this case, the image file server 25 transmits the captured image to the liquid crystal projector 18 when determining that the display form on the screen of the imaging device 12 is a form to be synchronized.

  In each embodiment, the image captured by the imaging device 12 is transferred to the display processing device 24 or the image file server 25 and stored. In the modification, the imaging device 12 may hold the captured image as it is inside the imaging device 12. In that case, the display processing device 24 of the first embodiment mainly has only an external display as its function, and it is sufficient to make it function substantially the same as the liquid crystal projector 18. The imaging device 12 transmits the captured image and the control information to the display processing device 24 or the liquid crystal projector 18 as an external display device, and determines whether to display them synchronously based on this control information.

  In each embodiment, the display form in the imaging device 12 is determined based on an event notification or an argument included in the control information. Although the range of the data area is particularly exemplified as the argument, in the modification, attributes such as the size, file name, and file format of the data instructing transfer are used as arguments, and the display of the imaging device 12 is displayed based on such arguments. The form may be determined. In addition, the event notification is mainly assumed to store and play back a captured image, but in a modified example, an event notification related to image processing may be used. Arguments in that case include the area range and coordinates to be processed, the enlargement / reduction ratio, and the like.

  Further, when a so-called slide show is executed in which a plurality of images are switched and displayed continuously every few seconds in the imaging device 12, the same content as that during normal playback is displayed from the imaging device 12 as the event notification. It is sent to the file server 25 every few seconds. Therefore, slideshow synchronization can also be realized with the configuration described in each of the above embodiments.

  The display processing device 24, the image file server 25, and the liquid crystal projector 18 in each embodiment are configured to execute synchronous display only when they are in a form that should be synchronized. The display processing device 24, the image file server 25, and the liquid crystal projector 18 in the modification include a unit that switches between a mode that synchronizes only in a fixed case and a mode that synchronizes all display contents as in the above embodiment. It is good.

  In each embodiment, the description has been made mainly assuming the synchronous display of the still image. However, in the modified example, it may be configured to determine whether to synchronize in the synchronous display of the moving image based on the same reference.
