Abstract

PROBLEM TO BE SOLVED: To realize display suitable for comparing respective images taken after a lapse of time at the same place and confirming how the images have changed, without applying a burden on a user.SOLUTION: When an image is selected optionally, the imaging position and the imaging direction of the "selected image" are identified by referring to additional information added to the "selected image", and a subject imprinted within the selected image is recognized. On the basis of the identified imaging position and the imaging direction and the recognized subject, image retrieval is performed to read and display an image similar to the imaging position, the imaging direction, and the subject more than predetermined similarity, as a "similar image".

Description

  The present invention relates to an image display device and a program for displaying a captured image.

  In general, if many images taken at the same place every year are displayed on the image display device and compared, for example, how children and plants grow, how the city develops, how events change, etc. Although it can be easily confirmed, it takes time and effort for the user to search for an image taken at the same place from a large number of taken images. In such a case, for example, if a technique for calling and displaying each image captured in the same place (imaging position) in the past is used, the burden on the user should be able to be reduced. As this type of technology, there is conventionally known a technology that displays a landscape image taken at the same position as a map of a specified age by storing a landscape image together with its shooting position and shooting date and time. (See Patent Document 1). A technique is also known in which monitoring is performed while comparing past images taken in the same direction at the same location as the current image (see Patent Document 2).

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
This embodiment is a block diagram showing basic components of a digital photo frame as a reproduction-only device applied as an image display device.
The digital photo frame is a stand-type or wall-mounted type that can be freely installed at a desired location. A slide show function that sequentially reads and plays back multiple image data, a list function that displays a list of multiple image data as thumbnails, and image data reception It has a communication function to be acquired, a time measuring function for measuring the current date and time, and the like, and is configured to operate with the control unit 1 as a core. The control unit 1 operates by supplying power from a power source unit (for example, a commercial power source or a secondary battery) 2 and controls the overall operation of this digital photo frame according to various programs in the storage unit 3 A device, a memory (not shown), and the like are included. The storage unit 3 is configured by combining two or more such as a ROM, a RAM, a hard disk, and a flash memory, and includes a program storage unit M1, an image data storage unit M2, a temporary information storage unit M3, and the like.

  The program storage unit M1 stores programs and various applications for realizing the present embodiment in accordance with the operation procedures shown in FIGS. 4 to 6, and stores various information necessary for the programs. ing. The image data storage unit M2 is an area for storing and storing each captured image (still image data, moving image data) captured by an imaging device (not shown) for reproduction, and stores each image data in a file format. ing. Note that image data stored in a memo pad or address book (not shown) may be stored in the image data storage unit M2. The additional information (for example, file header information) of each image data includes items of “shooting position”, “shooting direction”, “shooting date / time”, and “shooting condition”. “Shooting position” is, for example, longitude and latitude information (GPS information) acquired by the above-described imaging device during imaging. The “shooting direction” is a direction from the shooting position to the subject. “Shooting date / time” is year / month / day / hour / minute / second information, and “Shooting condition” is shooting equipment, exposure setting, and the like. The temporary information storage unit M3 is a work area that temporarily stores various kinds of information necessary for the operation of the digital photo frame, such as flag information and screen information.

  The display unit 4 uses, for example, a high-definition liquid crystal display, an organic EL (Electro Luminescence) display, an electrophoretic display (electronic paper), etc., for example, displays image data with high definition. The image data stored in the image data storage unit M2 is read and displayed on the display unit 4. The display unit 4 is provided with a contact operation unit (transparent touch panel) for detecting finger contact on the surface thereof. For example, a capacitive type, a resistive type, a piezoelectric type touch screen (touch type) Screen). When the initial menu screen is displayed on the touch screen and the position of the desired menu item is touched (selected) from the menu screen, the control unit 1 changes the touched (selected) menu item to the selected menu item. Perform the corresponding process. Although not shown, the operation unit 5 includes, for example, a key for turning on / off the power, and the control unit 1 performs processing according to an input operation signal from the operation unit 5.

  The card IF (interface) 6 transmits / receives image data to / from a memory card (not shown) inserted and connected to a card slot (not shown), and each image taken by an imaging device (not shown). Data is acquired via a memory card (for example, an SD card). At this time, the control unit 1 reads image data from the memory card connected to the card IF 6. Although not shown, a USB (Universal Serial Bus) interface may be provided to read image data from the USB memory.

  The communication unit 7 can be connected to the network 8 via the antenna AT. The network 8 is, for example, a wireless LAN (private network) or a public mobile communication network (public wireless line), for example, at home. Side or the communication carrier side. That is, a plurality of storage devices 9 are connected to the network 8, and the control unit 1 uploads image data (captured images) to the external storage device 9 via the network 8, or external storage. Image data is downloaded from the device 9, and at that time, any one of the storage devices 9 is arbitrarily designated, and the image data is transmitted to and received from the storage device 9. Additional information added to the image data in the external storage device 9 includes “shooting position”, “shooting direction”, “shooting date and time”, “shooting conditions” items such as shooting equipment and exposure settings. have. The digital photo frame is a thin client terminal that stores image data in the external storage device 9 and reads image data from the storage device 9 when connected to the external storage device 9 via the network 8. Will function as.

FIG. 2 is a diagram illustrating a search result when an image is searched based on a selected image selected by a user operation.
An arbitrary image is selected by a user operation from the image data read from the image data storage unit M2, the image data read from the memory card via the card IF 6, and the image data received and acquired from the communication unit 7 via the network 8. Then, the control unit 1 refers to the additional information added to the selected image, specifies the shooting position and shooting direction, and analyzes the selected image to be copied into the selected image. After recognizing the subject, the contents of the image data storage unit M2, the memory card, and the external storage devices 9 are searched based on the shooting position, shooting direction, and recognized subject. In this case, images similar to the shooting position, shooting direction, and subject are searched. At that time, images similar to a predetermined similarity or higher are searched. As a result, when an image similar to a predetermined similarity or higher can be searched, this search image is read as a “similar image” for the selected image, and is similar in shooting position and shooting direction. If the image is not similar to the subject, the search image is read as a “reference image” for the selected image.

FIG. 3 shows an image list (similar image list and reference image list) created based on the search result of the image search process described above and a display for selecting a display format indicating how to display the image list. It is a figure for demonstrating a flag.
If the image data obtained by the image search process is “similar image”, the control unit 1 additionally registers it in the similar image list L1, and if it is “reference image”, additionally registers it in the reference image list L2. An image list (similar image list, reference image list) is created. It should be noted that “internal” information is added to each of the image lists L1 and L2 if the acquisition destination is the image data storage unit M2, and if the acquisition destination is a memory card, any one of a plurality of cards is used. Information is added to indicate whether or not the storage device 9 is an external storage device 9 such as “card (1)” or card (2). In order to indicate this, information of “external (1) or external (2)” is added.

  When displaying the image lists (similar image list, reference image list) L1 and L2, in this embodiment, a display format indicating how to display the image list can be arbitrarily selected by a user operation. Yes. That is, when the value of the display flag F is “0”, a display format for displaying the contents of the image list as a slide show in order of shooting date and time is selected. When the value of the display flag F is “1”, the contents of the image list are selected. A display format for displaying the slide show in the order of shooting date and time is selected. When the value of the display flag F is “2”, a display format for displaying the contents of the image list as a thumbnail list is selected.

  Next, the operation concept of the digital photo frame in the present embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

4 and 5 are flowcharts showing an outline of the operation of the digital photo frame in the characteristic part of the present embodiment, and the execution is started in response to power-on.
First, after executing initialization processing such as clearing various memories (step A1 in FIG. 4), an initial menu screen is displayed on the display unit 4 (step A2). This menu screen displays “Image list display”, “Slide show display”, “Similar image search”, and “Others” menu items, and the user can perform touch operations on arbitrary item positions from the menu items. Do.

  When an operation of touching the item position of “image list display” (list display operation) is performed (YES in step A3), the image data stored in the image data storage unit M2 in the storage unit 3 is accessed. At the same time (step A4), the memory card is accessed via the card IF 6 (step A5), and the image data corresponding to the user stored in the external storage device 9 is accessed from the communication unit 7 via the network 8. (Step A6). Then, each image data in the image data storage unit M2, each image data in the memory card, and each image data in the external storage device 9 are converted into thumbnail images and displayed as a list on the display unit 4 (step A7). . If all the image data cannot be stored in one screen of the display unit 4, the contents of the list display can be freely changed by a screen switching operation or a scroll operation. .

  In this state, it is checked whether an operation of touching the display position (thumbnail selection operation) is performed to select an arbitrary thumbnail image desired by the user from the list screen (step A8), or the end of the list display It is in an operation waiting state while checking whether or not an ending operation for instructing has been performed (step A9). When a thumbnail selection operation is performed (YES in step A8), the screen is switched to a screen for displaying the selected image (step A10), and the selected image is temporarily stored in the temporary information storage unit M3 (step A11). ). Then, in response to the end operation for instructing the end of display of the selected image (YES in step A12), the menu display is returned (step A2). Also, when the list display end operation is performed (YES in step A9), the menu display is returned (step A2).

  When an operation (slide show operation) for touching the item position of “slide show display” is performed from the menu screen (YES in step A13), the image data stored in the image data storage unit M2 is accessed. (Step A14), the memory card is accessed via the card IF 6 (Step A15), and each image data stored in the external storage device 9 is accessed from the communication unit 7 via the network 8 (Step A16). . Then, a slide show display for sequentially displaying each image data in the image data storage unit M2, each image data in the memory card, and each image data in the external storage device 9 on the display unit 4 is started (step A17). Then, it waits for an operation while checking whether or not a slide show display pause operation has been performed (step A18) or checking whether a slide show display end operation has been performed (step A19).

  If a pause operation is performed (YES in step A18), the image at the time of the pause operation is stopped and displayed as a selected image (step A20). Then, after the temporarily displayed image is temporarily stored in the temporary information storage unit M3 as a selected image (step A21), in response to an end operation for instructing the display end of the selected image (YES in step A22), Return to the menu display (step A2). Also, when the slide show display end operation is performed (YES in step A19), the menu display is returned (step A2).

  On the other hand, when an operation of touching an item position other than the “image list display” and “slide show display” items on the menu screen is performed (NO in step A13), an operation of touching the “similar image search” item position. It is checked whether (similar image search operation) has been performed (step A23 in FIG. 5), or whether an operation to touch the item position of “others” (other operations) has been performed (step A24). . When other operations are performed (YES in step A24), as other processing corresponding to the operations, for example, image data is registered in the image data storage unit M2, or unnecessary images are stored in the image data storage unit M2. After processing for deleting data (step A25), the process returns to step A2 in FIG.

  When a similar image search operation is performed (YES in step A23), “shooting position”, “shooting direction”, “shooting date and time”, “shooting” are selected from the additional information added to the selected image in the temporary information storage unit M3. "Condition" is acquired (step A26). Then, by analyzing the selected image, a subject (for example, a person, a pet, etc.) imprinted in the selected image is recognized (step A27). That is, a process for recognizing the subject is performed by analyzing the selected image, identifying the subject portion, extracting the feature, and comparing it with the feature of the registered image that has been photographed and registered in advance. . Thereafter, each image data stored in the image data storage unit M2 is accessed (step A28), search processing for searching the image data is performed (step A29), and the memory card is accessed via the card IF6. (Step A30), a search process for searching the image data is performed (step A31), and each image data stored in the external storage device 9 is accessed via the network 8 from the communication unit 7 (step A31). A32), search processing for searching the image data is performed (step A33).

FIG. 6 is a flowchart for explaining the search process (steps A29, A31, A33 in FIG. 5) in detail.
First, the control unit 1 designates one of the search target images by using each image data in the image data storage unit M2, each image data in the memory card, and each image data in the external storage device 9 as a search target. Then, “shooting date” is read from the additional information added to the designated image (step B1). Then, the current date and time is acquired (step B2), and it is checked whether the “shooting date and time” has not passed a predetermined period (for example, 10 years or more) from the current date and time, that is, whether the image is too old (step B3). .

  Here, if the image is too old for a predetermined period since shooting (NO in step B3), the process proceeds to step B12 in order to exclude the designated image from the search target. If “YES” in step B3, “shooting position” and “shooting direction” are read from the additional information of the designated image (step B4), and compared with the “shooting position” and “shooting direction” of the selected image. It is determined whether or not the “photographing position” and “photographing direction” of the selected image and the “photographing position” and “photographing direction” of the selected image are more than a predetermined similarity (step B5). Here, “similarity of a predetermined similarity or higher” means that the “photographing position” and the “photographing direction” are substantially the same, as long as it is possible to confirm that both images are photographed at substantially the same place.

  If the “photographing position” and “photographing direction” between the designated image and the selected image are not similar to a predetermined similarity or higher (NO in step B5), it is determined that the image is taken at another location. In order to exclude the designated image from the search target, the process proceeds to step B12. Further, if the “photographing position” and “photographing direction” between the designated image and the selected image are more than a predetermined similarity (YES in step B5), “imaging condition” is read from the additional information of the designated image ( Step B6) Compares with the “shooting condition” of the selected image to determine whether the “shooting condition” of the designated image matches the “shooting condition” of the selected image (step B7).

  If the “shooting conditions” of the designated image and the selected image do not match (NO in step B7), the process proceeds to step B12 to exclude the designated image from the search target. If the “shooting condition” of the image is matched (YES in step B7), the subject (for example, person, pet, etc.) imprinted in the designated image is recognized (step B8) and compared with the subject of the selected image. Then, it is determined whether or not the subject is similar to a predetermined similarity (step B9). Now, if the designated image and the selected image are similar to the “shooting position” and “shooting direction” and the subjects are similar to each other with a predetermined similarity or more (YES in step B9), the designated image is taken as the “shooting date and time”. To the similar image list L1 (step B10).

  In addition, the designated image and the selected image are similar in “shooting position” and “shooting direction”, but if the subject is not similar to a predetermined similarity or more (NO in step B9), the designated image is displayed. Are added to the reference image list L2 together with the “shooting date and time” (step B11). Then, the process proceeds to step B12, and the next image data is designated from the image data in the image data storage unit M2, the image data in the memory card, and the image data in the external storage device 9 (step B12). ). Then, it is checked whether or not an unspecified image remains (step B13). If an unspecified image remains (NO in step B13), the process proceeds to the first step B1, and all the image data are specified below. The above operation is repeated until the end.

  When the search process (steps A29, A31, and A33 in FIG. 5) is completed in this way, it is checked whether data exists in the similar image list L1 (step A34), or whether data exists in the reference image list L2. (Step A35). If there is no data in any of the image lists L1 and L2 (NO in step A35), the process returns to step A2 in FIG. 4 where the menu screen is displayed, but there is data in the similar image list L1. If this is the case (YES in step A34), the display flag F is referred to and it is checked whether the value is "1" (step A36), "2" or "0" (step A37). Here, if the value of the display flag F is “1” (YES in step A36), the “photographing date / time” of each image data in the similar image list L1 is referred to, and the image data is sorted in the oldest shooting order. The operation for displaying the slide show together with the “shooting date” is started (step A38).

  If the value of the display flag F is “2” (YES in step A37), the “shooting date / time” of each image in the similar image list L1 is referred to, and each image data is set to “shooting” in the order of shooting. The operation of displaying the slide show together with the “date and time” is started (step A39). After the slide show display is started in this way (steps A38 and A39), the process returns to step A18 in FIG. 4 to wait for a pause operation or a slide show display end operation (steps A18 and A19 in FIG. 4). .

  If the value of the display flag F is “0” (NO in step A37), each image data in the similar image list L1 is displayed in a list together with the “shooting date / time” (step A40). After that, the process returns to step A8 in FIG. 4 to wait for a thumbnail selection operation or a list display end operation (steps A8 and A9 in FIG. 4). On the other hand, if there is data in the reference image list L2 (YES in step A35), each image data in the reference image list L2 is displayed in a list together with its “shooting date” (step A41). After that, the process returns to step A8 in FIG. 4 to wait for a thumbnail selection operation or a list display end operation (steps A8 and A9 in FIG. 4).

  As described above, in this embodiment, the control unit 1 refers to the additional information of the selected image, specifies the shooting position and shooting direction, and recognizes the subject imaged in the selected image. Then, the image search is performed based on the identified shooting position and shooting direction and the recognized subject, and an image similar to the shooting position and shooting direction and the subject is displayed at a predetermined similarity or higher. Compared with images taken over time, it is possible to realize an image display suitable for confirming the state of change without burdening the user, which is highly convenient. For example, by comparing children's photos taken at the same place on their birthday every year, you can see their growth at a glance, and by comparing a specific subject of a regular event like a festival float, There is an effect that can be seen at a glance.

  Since images whose shooting date and time have passed for a predetermined period or more from the current date and time are excluded from the search target, images that are too old to be compared can be excluded from the search target, and the search efficiency is improved accordingly. In addition, the recognition rate of the subject can be increased.

  Searching for images that have a shooting position and shooting direction that are similar to or higher than the predetermined similarity and that have the shooting conditions that satisfy the predetermined conditions, so only images that were shot with the same shooting equipment, exposure settings, etc. Can be limited as a search target, so that the search efficiency can be improved and the recognition rate of the subject can be increased.

  Since the shooting date and time are displayed together with the search image, the user can know at a glance when the image was taken.

  Since multiple images are displayed in the order according to the shooting date and time, they can be displayed in order from the newest date and the oldest time, and the state of change according to the passage of time (growth and development, etc.) Can be confirmed sequentially.

  Since a plurality of searched images are displayed in a list, the state of transition can be compared on the same screen.

  Search multiple images stored in the storage unit 3 and multiple images stored in the memory card via the card IF 6 so that all images stored in the digital photo frame are searched. Can be targeted.

  Since the image in the external storage device 9 connected from the communication unit 7 via the network 8 is set as the search target, the search target including the enormous number of images exceeding the memory capacity of the digital photo frame main body is included. can do.

  In addition to searching for an image similar to the shooting position and shooting direction and the subject as a similar image, an image similar to the shooting position and shooting direction but not similar to the subject is searched as a reference image. There is a possibility that an image unexpected by the user can be found by the search, and the enjoyment can be expanded.

  Each searched image is displayed based on the display format specified by the user in advance. Select the display according to whether you want to compare the images over time or check the changes in a short time. Can be flexible.

  In the above-described embodiment, the case where an image captured randomly is displayed as an example. However, the present invention is similarly applied to fixed-point observation in which an image captured periodically is displayed and observed. You can also.

  In the above-described embodiments, the case where the present invention is applied to a digital photo frame as an image display device has been shown, but the present invention is applied to a personal computer (PC), a mobile phone, a desktop electronic calculator, a handy terminal, a wristwatch, a PDA, a digital camera, a music player, and the like. You may make it do.

  In addition, the “apparatus” and “machine” shown in the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.
