  2. Description of the Related Art Conventionally, there are digital cameras, smartphones, and the like as electronic devices such as an imaging apparatus having a function of capturing a plurality of images having different shooting directions and angles of view. In addition, as an electronic device such as a display device having a function of reproducing and displaying the plurality of images, there is a television receiver (hereinafter sometimes referred to as “TV”), a notebook PC, or the like. The image is a still image or a moving image. The photographing direction can be defined by, for example, an azimuth angle and an elevation angle. The angle of view represents an image range as an angle and is also referred to as a viewing angle. For example, the angle of view can be defined by a horizontal angle of view corresponding to an azimuth angle and a vertical angle of view corresponding to an elevation angle.

  Images with different angles of view include images taken at a relatively wide angle (hereinafter sometimes referred to as “wide-angle image”, “first image”, etc.), and images taken at a relatively narrow angle. (Hereinafter may be referred to as “narrow angle image”, “second image”, etc.). Examples of the wide angle include a horizontal angle of view of 120 ° and an angle of view of 180 ° or more. In the case of 180 °, it may be called a hemispherical image, and in the case of 360 °, it may be called a omnidirectional image. As an example of the narrow angle, a field angle of 45 ° or less in the horizontal field angle can be given. Hereinafter, the unit of angle is expressed in degrees (°), but it can be converted into a unit such as radians.

  JP-A-2000-92439 (Patent Document 1) is given as an example of the prior art relating to screen display of a captured image.

For example, as shown in FIG. 1, the display device 2 communicates with the server 3, the imaging device 1, or the display device 2 other than its own device via the communication network 4, and transmits an image file 24 of its own device, or an external device The image file 24 is received from the device. At that time, the communication interface unit 208 transfers the communication data of the image file 24.

  The display control unit 212 controls the display unit 204 and the like to display images and information on the display screen of the display unit 204. The display control unit 212 reproduces and displays folder information and images on the display screen of the display unit 204 based on the image file 24 and the management information 21. The display control unit 212 provides various screens serving as a graphical user interface for the user. The display control unit 212 controls screen switching according to the display mode.

  The associating unit 215 performs association processing for associating a plurality of images having a predetermined relationship in cooperation with the display control unit 212. The associating unit 215 can also perform associating processing on the image file 24 acquired from an external device. The association process of the association unit 215 is the same as the association process of the association unit 15. When associating the first image and the second image as a result of the determination, the associating unit 215 describes the association information in the metadata 22 or the management information 21 of the image file 24 of the first image and the second image.

  When the image is reproduced and displayed, the display control unit 212 has a predetermined relationship based on the determination result of the association unit 215 or the reference confirmation of the metadata 22 or the management information 21 of the associated image file 24. One image and a second image are specified, and a plurality of images including the first image and the second image are displayed in a state associated with the display screen.

  Hereinafter, the imaging apparatus 1 will be mainly described. However, functions other than the functions and operations related to imaging can be realized in the same manner with the display apparatus 2 as the main body.

[Imaging device-appearance]
FIG. 4 shows an example of the external configuration of the imaging apparatus 1. The left side of FIG. 4 shows a configuration viewed from the back side of the casing 400 of the imaging apparatus 1, and the right side shows a configuration viewed from the right side of the casing 400. The rear surface is the surface on which the display screen 401 of the display unit 41 is provided, and the front surface is the surface on which the lens 402 of the imaging unit 103 is provided.

  In the configuration of the side surface, the lens 402 of the lens unit 32 is disposed at the front center position of the housing 400. In addition, an electronic viewfinder (EVF) 403 is provided in a state of projecting upward with respect to the main housing 400, for example. The EVF 403 is one of the display devices 104.

  In the rear configuration, a rectangular display screen 401 corresponding to the touch panel described above is arranged, and information display and touch input operations are possible. The EVF 403 includes a display screen 404 and a proximity sensor 405. The EVF 403 displays an image of a subject as a photographic monitor image based on a signal input via a lens and an image sensor at the time of photographing. The user can shoot while confirming the shooting monitor image of the EVF 403. On the display screen 404, information such as an aperture value may be superimposed and displayed. The proximity sensor 405 detects the proximity of an object. The proximity sensor 405 includes a capacitance method, an optical method, and the like. For example, the control unit 101 determines whether the user uses the EVF 403 by detecting the presence / absence of proximity through the proximity sensor 405. The control unit 101 automatically switches between display on the display screen 401 and display of the captured monitor image on the display screen 404 of the EVF 403 according to the determination. In addition, not only EVF403 but the form which mounts an optical finder may be sufficient. In addition, a mode for displaying a photographic monitor image on the display screen 401 can be set.

  The casing 400 is provided with a mode setting dial 431, a shutter button 432, a cross key 433, a playback display mode button 434, a power button 435, and the like as the operation input unit 105. The cross key 433 includes up / down / left / right buttons and a center button, and can be used for input of selection, determination, and cancellation of information on a desired position in the display screen 401. On the display screen 401, a menu can be displayed based on a predetermined input operation.

  The mode setting dial 431 is used for setting an operation mode. The shutter button 432 is pressed during shooting. The playback display mode button 434 is used when playback is displayed on the display screen 401, and the display mode can be switched. The power button 435 is used for power on / off and the like. The user can perform various input operations such as displaying a photographing monitor image on the display screen 401 or the display screen 404 and touching a desired position to adjust the focus.

[Imaging device-operation mode]
The operation mode of the imaging apparatus 1 includes a shooting mode, a playback display mode, and the like. The outline of operation in the shooting mode is as follows. When the user presses the power button 435 to turn on the power, the normal shooting mode is activated. The control unit 101 drives and controls the imaging unit 103 and the like according to the normal shooting mode. In the normal shooting mode, still images and moving images can be shot as images. At the time of shooting, the control unit 101 reads out an imaging signal from the imaging unit 103 at a predetermined cycle, performs predetermined signal processing at the signal processing unit 132 via the interface circuit unit 131, and converts it into a video signal in a display format. . Based on the video signal, the control unit 101 displays the shooting monitor image on the display screen 401 of the touch panel of the display device 104 or the display screen 404 of the EVF 403 in real time. The user performs shooting as follows while confirming the shooting monitor image on the display screen 401 or the display screen 404.

  The user sets angle-of-view related information and the like as shooting conditions in the setting unit 14 through the operation input unit 105. When shooting a still image, the user presses the shutter button 432. The imaging control unit 11 detects pressing of the shutter button 432, and determines an aperture value, a shutter speed, a focus, and the like according to the set shooting conditions. For example, the shutter button 432 is half pressed or fully pressed. The imaging control unit 11 performs control so as to set a focus or the like when in a half-pressed state and to start imaging when in a fully-pressed state.

  The still image pickup signal picked up by the image pickup unit 103 is subjected to predetermined signal processing for a still image using the signal processing unit 132 and the memory 133. For example, JPEG is applied as an encoding method at that time, but MPEG or a high-quality RAW format may be applied as another method. The image file 24 corresponding to the encoded still image data is recorded on the recording medium 107 by the recording unit 106, for example.

  When shooting a moving image, the user starts moving image shooting by pressing the moving image shooting button, and stops moving image shooting by pressing the moving image shooting button again. A moving image pickup signal is subjected to signal processing of a predetermined method for moving images. As the system, for example, MPEG such as H264 and H265, and other formats are applied. The encoded moving image data is similarly recorded on the recording medium 107, for example.

  The outline of the operation in the playback display mode is as follows. When the control unit 101 detects that the playback display mode is set by the playback display mode button 434, the control unit 101 reads the image file 24 from the recording medium 107 of the recording unit 106 and stores it in the storage unit 102. The display control unit 12 uses the signal processing unit 132 to restore the original image data from the image data 23, and generates video data for displaying an image or the like on the display screen. The display control unit 12 controls the display device 104 based on the video data and displays an image or the like on the display screen.

[Management information and image files]
FIG. 5 shows a configuration example of the management information 21 and the image file 24 in the storage unit 102. The management information 21 includes image file management information and association management information. The image file management information is information managed by a known file system, and includes, for example, information such as a file name, update date / time, type, and size. The association management information is unique information created to manage the relationship between a plurality of images. The association management information includes, for example, a type identifier, a reference identifier, and a setting character string.

  The type identifier is an identifier for identifying the type of the image for each image file 24. There are two types of images, for example, wide-angle images and narrow-angle images. The reference identifier is an identifier for referring to association between a plurality of images. The reference identifier is, for example, the file name of the image file 24 of the second image to be referenced as a reference identifier for the first image when there is a first image and a second image associated therewith. Further, the file name of the image file 24 of the first image as a reference source is used as a reference identifier for the second image. Although described later, the setting character string is a character string that can be arbitrarily set by the user based on a user operation. The user can set, for example, a character string representing a shooting location for an image when editing and managing the image. Although the setting character string is provided in the association management information, the setting character string may be provided in the metadata 22.

  The image file 24 includes metadata 22 and image data 23. The header portion of the image file 24 has metadata 22 and the body portion has image data 23. The image data 23 is still image data or moving image data, and is encoded data in the case of recording. The metadata 22 is data for managing information including various attribute values related to the image data 23. In other words, the metadata 22 is attached information and attribute information. The metadata 22 includes information items such as shooting date and time, shooting location, model, resolution, shooting direction, field angle, field angle related information, rotation angle, and thumbnail.

  The shooting date / time is, for example, year / month / day / hour / minute / second. The shooting location includes position information or a setting character string. The position information includes the position coordinates {latitude, longitude, altitude} detected by the position detection unit 113. The setting character string is a character string that represents the shooting location set by the user. The model is information that uniquely represents the type of the imaging apparatus 1. The model may include a lens type or the like. The resolution represents the resolution of the image data 23.

  The shooting direction is information including an azimuth angle (referred to as θ) and an elevation angle (referred to as φ). The angle of view is information including a horizontal angle of view (Ah) and a vertical angle of view (Av). The angle-of-view related information is information such as an electronic zoom magnification (n), a focal length (f), and the size of the imaging surface of the image sensor. The dimensions are {horizontal size sw, vertical size sh, diagonal size sd}. In the metadata 22, only one of the view angle item and the view angle related information item may be provided.

  In other words, the rotation angle is a rotation about the optical axis of the lens at the time of imaging, and is an angle representing the rotation of the image at the time of imaging. For example, the angle and direction are based on the state in which the horizontal direction of the casing 400 matches the horizontal plane as shown in FIG.

  The thumbnail is a reduced image based on the original data of the image. The thumbnail is configured according to the resolution, type, and the like of the image, and is recorded with or without encoding. When thumbnails are created and held in advance, thumbnails can be displayed at high speed during playback display. A plurality of types of thumbnails may be created and held at different resolutions. The thumbnail may be omitted or may be managed separately from the metadata 22. The display control unit 12 may create and display thumbnails for each reproduction display.

  The metadata 22 is in a format expanded based on a predetermined format, for example, Exif (Exchangeable image file format), but is not limited thereto. Exif is a format for digital camera photos. In Exif, model and shooting condition information is embedded in image data as metadata. Image display and image editing software can refer to this metadata, and the user can edit metadata information. The metadata of the conventional Exif image file does not include information such as the angle of view. In the first embodiment, items such as angle of view and angle-of-view related information are provided as specific information items in the metadata 22 as an expanded format.

  The metadata 22 is created and managed as a header part of the image file 24, but may be created and managed as a metadata file separately from the image data file. Further, the management information 21 is not limited to managing specific information using the metadata 22, and similar information may be managed in the management information 21. In the case of a moving image, various information such as the metadata 22 may be described for each image frame at a predetermined time interval, for example. The time interval may be constant or only when the angle of view is changed.

[Managing relationships between multiple images]
FIG. 6 shows association management related to the relationship between a plurality of images. For example, the control unit 101 manages the relationship shown in FIG. 6 in the association management information in the management information 21 shown in FIG. In FIG. 6, the first image has a wide angle type, and the second image has a narrow angle type. In this example, the first image includes a first wide-angle image, a second wide-angle image, and the like, and the second image includes a first narrow-angle image, a second narrow-angle image, and the like. For example, a plurality of second images such as a first narrow-angle image, a second narrow-angle image, and a third narrow-angle image are associated with the first wide-angle image. As the association information, for example, an image file name such as the first narrow-angle image is provided as a reference identifier to be given to the image file of the first wide-angle image. Further, the image file name of the first wide-angle image is used as a reference identifier to be given to the image file of the first narrow-angle image. Thereby, it is possible to refer to each other between related images.

  Note that information representing the relationship between a plurality of images as shown in FIG. 6 may be displayed on the display screen as one display mode. At this time, as shown in FIG. 6, the first image and the second image may be displayed in a tree structure, and although not shown, the nodes of the second image are connected by link lines around the nodes of the first image. May be displayed.

  In the first embodiment, a wide angle and a narrow angle related to the angle of view are distinguished as image types. The imaging apparatus 1 distinguishes the angle of view by an absolute value based on the threshold value. The first angle of view is set as the threshold for the angle of view. The control unit 101 selects a wide-angle image as the type when the angle of view of the captured image is equal to or larger than the first angle of view, and a narrow-angle image when the angle of view is less than the first angle of view. Not limited to this, three or more types of angle of view may be provided.

[Image direction and angle]
FIG. 7 is an explanatory diagram simply showing the concept of the relationship between the shooting direction and the angle of view for a wide-angle image and a narrow-angle image that are a plurality of images used as specific examples in the imaging apparatus 1 of the first embodiment. FIG. 7 particularly shows the azimuth angle and the horizontal angle of view.

  It has a wide-angle image 6a that is a first image, a first narrow-angle image 6b that is a second image, and a second narrow-angle image 6c. These images are images taken by the user using the imaging device 1 at the point P0 that is the same location. It is assumed that the images were taken at close dates in the order of the wide-angle image 6a, the first narrow-angle image 6b, and the second narrow-angle image 6c. The shooting date and time of each image is, for example, 13:11:30 on Jan. 5, 2016 for the wide-angle image 6a, 13:14:40 for the first narrow-angle image 6b, and the same date for the second narrow-angle image 6c. 13:15:50.

  The wide-angle image 6a has a shooting range 631 corresponding to the shooting direction 63a indicated by the azimuth angle θ1 and the horizontal angle of view Ah1. The first narrow-angle image 6b has an imaging range 602 corresponding to the imaging direction 63b indicated by the azimuth angle θ2 and the horizontal field angle Ah2. The second narrow-angle image 6c has a shooting range 63c corresponding to the shooting direction 63c indicated by the azimuth angle θ3 and the horizontal field angle Ah3. In FIG. 7, among the image capturing directions, the image capturing direction defined by the azimuth angle θ is indicated by a one-dot chain line.

  The point P0 particularly indicates the center point of the lens 402 of the imaging unit 103. A spherical surface 600 represents a spherical surface of an omnidirectional sphere, and is a virtual spherical surface obtained by discarding points at infinity. The spherical surface 600 particularly indicates a circumferential portion corresponding to the azimuth angle θ and the XY plane. N indicates north, E indicates east, S indicates south, and W indicates west. The X direction corresponds to the east, the Y direction corresponds to the north, and the Z direction corresponds to the zenith direction. The azimuth angle θ is indicated as 0 ° with N as the reference, clockwise as the positive direction, E as + 90 °, S as + 180 °, and W as + 270 ° (−90 °).

  An imaging range 601 indicated by an arc on the spherical surface 600 indicates a portion corresponding to the horizontal field angle Ah1 in the wide-angle image 6a, and corresponds to a region projected on the spherical surface 600 viewed from the point P0. In this example, a case where there are a mountain 611, a sky, a tower 612, a building 613, and the like as a landscape captured on the spherical surface 600 on the wide-angle image 6a is simply shown. The first narrow-angle image 6b is an example in which the tower 612 is photographed, and the second narrow-angle image 6c is an example in which the building 613 is photographed.

  Specific examples of values of azimuth angle θ, elevation angle φ, horizontal field angle Ah, and vertical field angle Av of each image are as follows. The wide angle image 6a has an azimuth angle θ1, an elevation angle φ1, a horizontal field angle Ah1, and a vertical field angle Av1, and the first narrow angle image 6b has an azimuth angle θ2, an elevation angle φ2, a horizontal field angle Ah2, and a vertical field angle Av2. It is assumed that the azimuth angle θ3, the elevation angle φ3, the horizontal field angle Ah3, and the vertical field angle Av3 of the angle image 6c.

θ1 = + 10 °, φ1 = 0 °, Ah1 = 120 °, Av1 = 80 °
θ2 = + 45 °, φ2 = 0 °, Ah2 = 21 °, Av2 = 14 °
θ3 = −20 °, φ3 = −10 °, Ah3 = 21 °, Av3 = 14 °
FIG. 8 is an explanatory view showing the elevation angle φ and the vertical angle of view Av, as in FIG. FIG. 8 shows an example of another narrow-angle image 6d. In FIG. 8, the X direction corresponds to the horizontal direction, and the Z direction corresponds to the vertical direction. The positive direction in the Z direction corresponds to the head and zenith direction, and the negative direction corresponds to the foot direction. The elevation angle φ is 0 ° with respect to the horizontal direction, + 90 ° in the zenith direction in the Z direction, and −90 ° in the foot direction. An imaging range 801 corresponding to the vertical field angle Av4 in the narrow-angle image 6d is shown. A shooting direction 63d of the narrow-angle image 6d indicates a portion corresponding to the elevation angle φ4.

[Field angle and field angle related information]
FIG. 9 simply shows the view angle and the view angle related information. FIG. 9 shows a case where the setting section 14 stores the field angle and field angle related information as setting information. As the field angle of the image, {horizontal field angle Ah, vertical field angle Av} are shown. Further, a horizontal size Sh corresponding to the horizontal angle of view Ah in the image and a vertical size Sv corresponding to the vertical angle of view Av are shown. The horizontal size Sh is a size from the right end to the left end in the horizontal direction in the image frame. The vertical size Sv is a size from the upper end to the lower end in the vertical direction in the image frame. In the first embodiment, the horizontal field angle Ah and the vertical field angle Av are used. However, the present invention is not limited to this, and at least one field angle including the diagonal field angle Ad may be used.

  As the angle-of-view information, the focal length f of the lens in consideration of the optical zoom, the electronic zoom magnification n, and the dimensions of the imaging surface of the imaging device {horizontal size sw, vertical size sh, diagonal size sd} are used. A model may be used instead of the dimensions. The focal length f is a 35 mm equivalent focal length.

  The angle of view can also be obtained by calculation based on the relational expression using the angle-of-view related information. When there is sufficient angle-of-view related information for calculating the angle of view, the control unit 101 may calculate the angle of view from the angle-of-view related information. The angle of view can be calculated using, for example, the dimensions of the image sensor, the focal length f, and the electronic zoom magnification n.

  When calculating the angle of view from the angle-of-view related information, it is as follows. The imaging control unit 11 refers to the angle-of-view related information regarding the image. The imaging control unit 11 can grasp the angle-of-view related information from the setting information of the setting unit 14 described above or information described in the metadata 22 or the management information 21. The angle of view {horizontal angle of view Ah, vertical angle of view Av, diagonal angle of view Ad} can be calculated based on the following equation, for example.

Ah = 2 × arctan (sw / (2 × n × f)) (1)
Av = 2 × arctan (sh / (2 × n × f)) (2)
Ad = 2 × arctan (sd / (2 × n × f)) (3)
The focal length f is usually expressed in terms of 35 mm. This corresponds to satisfying the above formula when the dimensions of the image sensor are 35 mm size {sw = 35 mm, sh = 24 mm}.

  For example, given the electronic zoom magnification n, the focal length f, and the dimensions {horizontal size sw, vertical size sh}, the horizontal field angle Ah1 and the vertical field angle Av1 are determined. The control unit 101 describes the field angle information in the field angle item of the metadata 22 or the management information 21. In addition, since the angle of view can be calculated from the angle-of-view related information, the imaging apparatus 1 may store the angle-of-view related information instead of saving the angle of view as one of the metadata 22 and the like. . In addition, since the dimensions of the image sensor of the angle-of-view related information can be grasped from the model, the image capturing apparatus 1 may store the model instead of the dimensions of the image sensor as one of the metadata 22 and the like. Good. For example, the imaging apparatus 1 holds information representing a correspondence relationship between the model and the angle-of-view related information in advance. Alternatively, the imaging device 1 can refer to information representing the correspondence relationship from an external device through communication. The imaging device 1 can obtain angle-of-view related information from the model based on the information.

[Save angle of view]
When the image pickup apparatus 1 picks up an image, the image pickup apparatus 1 creates information including a shooting date and time, a shooting direction {azimuth angle θ, elevation angle φ}, a field angle {horizontal field angle Ah, vertical field angle Av}, and the like. The imaging control unit 11 obtains the shooting date and time using the internal clock 112. The imaging control unit 11 obtains position information {latitude, longitude, altitude} by the position detection unit 113. The imaging control unit 11 obtains the imaging direction {azimuth angle θ and elevation angle φ} by the imaging direction measurement unit 111. The imaging control unit 11 obtains an angle of view {horizontal angle of view Ah and vertical angle of view Av} by setting information or calculation of the setting unit 14. Then, the imaging apparatus 1 describes the information in corresponding items of the metadata 22 in FIG. 5 and creates the image file 24 together with the image data 23.

[Display screen (1)-Display mode]
FIG. 10 shows a display mode of the display screen 401 of the display unit 41 and its transition. The imaging apparatus 1 has at least a first display mode, a second display mode, and a third display mode as display modes that are playback display modes. For example, the imaging apparatus 1 initially displays in the first display mode, and switches the display mode based on a user operation.

  The first display mode is a mode for displaying a list of information on all images, and is a mode for displaying a folder screen. On the first screen in the first display mode, information on a plurality of images in the folder is displayed in a list in the order of, for example, file names and date / time. In this example, information such as images G1, G2, and G3 is displayed as a plurality of images in order from the top. In each image row, an image icon or thumbnail, file name, shooting date, type, and other information are displayed. As other information, attribute values such as the shooting direction {azimuth angle θ, elevation angle φ} and field angle {horizontal field angle Ah, vertical field angle Av} may be displayed. The user can scroll and display information that cannot be displayed on the first screen. The first screen is not limited to such a folder screen, and various known methods are possible. For example, a screen that displays thumbnails of a plurality of images in a two-dimensional parallel arrangement is possible. On the first screen, the user selects and operates a desired first image, for example, the image G1 (corresponding to the wide-angle image 6a). In this case, when there is a second image associated with the selected first image, the imaging device 1 makes a transition to the second screen in the second display mode.

  The second display mode is a unique mode for performing association display in a plurality of images including a wide-angle image and a narrow-angle image. On the second screen in the second display mode, the wide-angle image 6a that is the selected first image 901 is displayed as a whole, and one or more second images having a predetermined relationship are displayed on the first image 901. A narrow-angle image is displayed in a state of being overlapped and related in a state of a predetermined graphic 902. For example, the graphic 902 is a graphic representing the first narrow-angle image 6b, and the graphic 903 is a graphic representing the second narrow-angle image 6c. Note that the broken line frame indicates a region where the corresponding narrow-angle image is present for easy understanding. On the second screen, the display state can be changed by an operation such as scrolling or enlarging / reducing according to the user operation.

  On the second screen, the user selects and selects a desired second image figure. The selection operation is, for example, a figure tap. In that case, the imaging apparatus 1 makes a transition to the third screen in the third display mode for displaying the selected second image. When a predetermined operation for returning to the first display mode is performed on the second screen, the imaging device 1 returns to the first screen in the first display mode. The predetermined operation is, for example, a first display mode designation input or a return button press.

  The third display mode is a mode for performing detailed display regarding a specified single image, for example, a narrow-angle image. In this example, a narrow-angle image that is a single second image 904 is displayed on the third screen, but a single wide-angle image can be displayed in the same manner. On the third screen in the third display mode, it is also possible to change the display state by scrolling, enlarging / reducing, or the like according to a user operation. When the user performs a predetermined operation on the third screen, for example, a second display mode designation input or a tap on the area of the second image 904, the imaging device 1 returns to the second screen in the second display mode.

  Further, when the user wants to browse only the wide-angle image, the imaging device 1 displays only the first image in detail on the display screen in accordance with a predetermined operation. For example, in response to a predetermined operation on the second screen, the imaging apparatus 1 hides the graphic of the second image, thereby displaying only the first image. The imaging device 1 returns the graphic of the second image to the display state again in response to a predetermined operation from that state. Alternatively, the imaging apparatus 1 transitions to a third screen that displays the first image in detail in response to a predetermined operation on the second screen, for example, a tap on a region where there is no figure of the second image on the first image. Let

[Display screen (2)-second display mode]
FIG. 11 shows an example of the second screen in the second display mode. This example corresponds to the specific example of FIG. 7 and the like, and shows a case where the wide-angle image 6a is selected and displayed. A case where the first narrow-angle image 6b and the second narrow-angle image 6c are associated with the wide-angle image 6a is shown. The display control unit 12 displays the second screen based on the image file 24 and the management information 21. On the second screen, the wide-angle image 6a that is the first image is displayed as a whole, and a graphic representing each narrow-angle image that is the second image is superimposed on the first image.

  In FIG. 11, the horizontal direction in the screen corresponding to the azimuth angle in the display screen 401 is shown as the x direction, and the vertical direction in the screen corresponding to the elevation angle is shown as the y direction. The horizontal width of the display screen 401 in the x direction is W, and the vertical width in the y direction is H.

  A point p <b> 1 indicates a central point on the display screen 401. Initially, the entire wide-angle image 6a is displayed in the display screen 401 in a state in which operations such as scrolling and enlargement / reduction are not performed. Initially, the position coordinate (Xa, Ya) of the center point corresponding to the shooting direction 63a of the wide-angle image 6a is displayed at the point p1. The position coordinates (Xa, Ya) are points corresponding to (θ1 = + 10 °, φ1 = 0 °) in terms of (azimuth angle, elevation angle).

  The horizontal angle of view Ah1 of the wide-angle image 6a is 120 °, and the vertical angle of view Av1 is 80 °. The wide-angle image 6a is displayed in a horizontal size Sh1 corresponding to the horizontal field angle Ah1 and a vertical size Sv1 corresponding to the vertical field angle Av1 in correspondence with the horizontal width W and the vertical width H of the display screen 401.

Association method
As the association method, there are a first method and a second method with respect to timing of associating. The first method is a method for performing association at the time of imaging, and the second method is a method for performing association at the time of reproduction display. In the first embodiment, the imaging device 1 uses the first method, and the display device 2 uses the second method.

  In the first method, the imaging device 1 performs association processing using the association unit 15 immediately after capturing an image, and as a result, the association information is described in the metadata 22 or the management information 21. When reproducing and displaying the image, the imaging apparatus 1 can grasp the relationship between the plurality of images from the reference to the association information of the metadata 22 or the management information 21 and displays the relationship on the display screen in the second display mode.

  In the second method, when the display device 2 reproduces and displays on the display screen based on the image file 24, the display device 2 performs an association process using the association unit 215, and as a result, displays on the display screen in the second display mode.

  In the second method, the display device 2 may omit the description of the association information in the metadata 22 or the management information 21 by performing the association process for each reproduction display. Alternatively, in the second method, the display device 2 performs association processing at the first reproduction / display of an image, describes the association information in the metadata 22 and the management information 21, and then reproduces the image for the second and subsequent times. At the time of display, the association process may be omitted with reference to the association information.

  Note that the second method may be employed in the imaging apparatus 1 according to another embodiment. Which of the association methods is adopted may be fixed in terms of mounting, or may be selected and set in accordance with user settings.

[Processing flow (1)]

FIG. 14 shows a flow of control processing when an image is picked up by the image pickup apparatus 1. FIG. 14 includes steps S101 to S106. The same processing is repeated every time an image is captured. Hereinafter, it demonstrates in order of a step.

  (S101) The control unit 101 sets an angle of view and the like for the setting unit 14 based on a user operation. The imaging control unit 11 grasps the angle of view and the like based on the setting information of the setting unit 14.

  (S102) Based on the user operation, the imaging control unit 11 controls the imaging unit 103 to capture an image, obtains image data 23, and stores the image data 23 in the storage unit 102. The imaging control unit 11 describes the angle of view or the angle-of-view related information in the metadata 22 or the management information 21 of the image file 24.

  (S103) Branching is performed according to the first method in which association is performed during imaging or the second method in which association is performed during playback display. In the case of the first method, the process proceeds to S104, and in the case of the second method, the process proceeds to S106. That is, the imaging apparatus 1 of the first embodiment proceeds to S104 in order to employ the first method, and proceeds to S106 when the second system is employed in the imaging apparatus 1 of the other embodiments.

  (S104) The associating unit 15 performs a predetermined associating process. Thus, a plurality of images including the first image and the second image are associated.

  (S105) The associating unit 15 creates association information as a result of the associating process, and describes it in the metadata 22 of the image file 24 or the management information 21. The imaging control unit 11 stores the image file 24 in the storage unit 102 and records it in the recording medium 107 of the recording unit 106.

  (S106) Since the imaging control unit 11 does not perform association at this time, the imaging control unit 11 creates metadata 22 and management information 21 that do not include association information. The control unit 101 stores the image file 24 in the storage unit 102 and records it on the recording medium 107 of the recording unit 106.

[Processing flow (2)]
FIG. 15 shows a flow of control processing at the time of reproducing and displaying an image in the imaging device 1 or the display device 2. The control in FIG. 15 corresponds to the control for changing the display mode as shown in FIG. FIG. 15 includes steps S201 to S210. Hereinafter, it demonstrates in order of a step. Hereinafter, the case where the imaging device 1 is the main body will be described, but the same applies to the case where the display device 2 is the main body.

  (S201) Based on the user operation, the control unit 101 causes the display control unit 12 to display the first screen in the first display mode on the display screen 401 of the display unit 41 of the display device 104 as shown in FIG. The display control unit 12 accepts selection of an image in the first screen in response to a user input operation.

  (S202) The display control unit 12 branches depending on whether the image selected on the first screen in the first display mode is a wide-angle image that is the first image or a narrow-angle image that is the second image. If it is the first image, the process proceeds to S203, and if it is the second image, the process proceeds to S209.

  (S203) The display control unit 12 performs branching according to the first method or the second method. In the case of the second method, the process proceeds to S204, and in the case of the first method, the process proceeds to S206. That is, in the case of the imaging apparatus 1 of Embodiment 1, since it is a 1st system, it progresses to S206, and in the case of the display apparatus 2, since it is a 2nd system, it progresses to S204.

  (S204) The display control unit 12 performs a process of associating a plurality of images using the associating unit 15 immediately before reproduction display.

  (S205) As a result of S204, the display control unit 12 reads the image data 23 of the second image associated with the first image.

  (S206) In the case of the first method, association processing has already been performed. The display control unit 12 confirms the association with reference to the association information in the metadata 22 or the management information 21 of the image file 24 of the first image. The display control unit 12 reads the image data 23 of the second image associated with the first image.

  (S207) The display control unit 12 displays the image data 23 as a result of S205 or S206 on the display screen in the second display mode. That is, the display control unit 12 displays the second image on the first image in a state of being associated with the first image, as in the second screen of FIG. The display control unit 12 accepts selection of a graphic of the second image in the second screen in accordance with a user input operation. For example, when the user wants to view the second image, the user taps the mark, and when he wants to return to the first screen, the user taps the area of the first image.

  (S208) The display control unit 12 branches depending on whether the image selected on the second screen in the second display mode is a mark representing the second image. If it is a mark representing the second image, the process proceeds to S209. In the case of another operation, for example, an operation on the area of the first image, this corresponds to a return operation, and in this case, the process returns to S201.

  (S209) The display control unit 12 uses the image data 23 of the second image corresponding to the mark selected in S208, in the third display mode on the display screen, as in the third screen in FIG. Two images are displayed in detail. The display control unit 12 receives a return operation or the like in the third screen in response to a user input operation. For example, when the user wants to return to the second screen, the user taps the area of the second image.

  (S210) If there is an input operation corresponding to the return operation on the third screen in the third display mode, the display control unit 12 returns to S207 as indicated by A1, and if there is no input operation, the display control unit 12 Continue to display the display mode. In addition, you may make it return to the 1st screen of 1st display mode from 3rd display mode according to predetermined | prescribed input operation.

[Association process (1)]
The associating unit 15 associates a plurality of images. The association process includes a first process and a second process. The first process is a process for selecting an image as a candidate for association based on a selection condition of a predetermined selection method. As the predetermined selection method, there are a first selection method, a second selection method, and a third selection method described below. In the first embodiment, the first method is used. In the modification, the second selection method or the third selection method is used. Note that which selection method is adopted may be a fixed form in terms of mounting or a form that can be variably selected by user settings.

[First selection method-shooting location]
FIG. 16 is an explanatory diagram showing the first selection method. The first selection method uses a condition related to the shooting location as a selection condition. In the first selection method, images that are determined to have roughly the same shooting location are selected as candidates. In the first selection method, position information {latitude, longitude, altitude} by the position detection unit 113 is used to determine the shooting location. When associating, the associating unit 15 refers to the position information {latitude, longitude} described in the shooting location item of the metadata 22 at the time of imaging, for example. {Latitude, Longitude} is represented by {LA, LO}.

  As shown in FIG. 16, the associating unit 15 takes a position 1601 representing the shooting location of the first image in the space, for example, the XY plane, with the wide-angle image as the first image as a reference. The position 1601 is represented by {LA1, LO1}. A position range 1600 corresponds to a threshold value of a condition, and indicates a circular area having a predetermined radial distance with the position 1601 as a central point. The radial distance that defines the position range 1600 may be a fixed set value in design or a set value that can be varied by user setting.

  The associating unit 15 compares the position of each narrow-angle image that is the second image with the position 1601 of the first image. In this example, a first narrow-angle image position 1602 {LA2, LO2}, a second narrow-angle image position 1603 {LA3, LO3}, and a third narrow-angle image position 1604 {LA4, LO4 around the wide-angle image. } Is shown. The associating unit 15 searches for an image included in the position range 1600 with respect to the position 1601 of the first image. In this example, the position range 1600 includes the position 1602 of the first narrow-angle image and the position 1603 of the second narrow-angle image, and does not include the position 1604 of the third narrow-angle image.

  The associating unit 15 determines that the second image whose position is included in the position range 1600 is an image captured at the same photographing location as the first image, and selects it as a candidate for association. As an example of the same photographing location, there is a case where a user photographs each direction of 360 ° while circling a circle along a handrail at a certain observation deck.

[Second selection method-shooting date and time]
FIG. 17 is an explanatory diagram showing the second selection method. The second selection method uses a condition related to the shooting date and time as a selection condition. In the second selection method, images that are determined to have substantially the same shooting date and time are selected as candidates. In association, the associating unit 15 refers to, for example, the shooting date (year / month / day / hour / minute / second) described in the shooting date / time item of the metadata 22.

  The associating unit 15 takes a time point t1 representing the shooting date and time of the first image with reference to the wide-angle image that is the first image in the time series of shooting date and time. In this example, it is assumed that the time point t1 is the date and time DT3. The date / time range 1700 corresponds to a threshold value of the condition, and indicates a range by a predetermined time including the time point t1 as a central point and before and after. Note that the time for defining the date and time range 1700 may be a fixed set value in design or a set value that can be varied by user setting. The date and time range 1700 can be set, for example, 1 day (24 hours), 1 hour, 5 minutes, or the like.

  The associating unit 15 searches for the second image included in the predetermined date and time range 1700 with respect to the time t1 of the shooting date and time of the first image. The associating unit 15 compares the shooting date and time of each narrow-angle image that is the second image with respect to the time t1 of the shooting date and time of the first image. In this example, there is shown a case where there is a time t2 of the first narrow-angle image shooting date, a time t3 of the second narrow-angle image, and a time t4 of the third narrow-angle image in the vicinity of the time t1. In this example, the time range 1700 includes the time point t2 of the first narrow-angle image and the time point t3 of the second narrow-angle image, and does not include the time point t4 of the third narrow-angle image. The control unit 101 determines that the second image whose time point is included in the date and time range 1700 is an image captured at approximately the same shooting date and time as the first image, and selects it as a candidate for association.

[Third selection method-setting character string]
FIG. 18 is an explanatory diagram showing the third selection method. The third selection method uses a condition relating to a set character string that can be arbitrarily set by the user as a selection condition. In the third selection method, images that are determined to have substantially the same set character string are selected as candidates. When associating, the associating unit 15 refers to, for example, a character string set as a setting character string of association management information after imaging.

  FIG. 18 shows an example of a list display of information of a plurality of images on the first screen in the first display mode. In this example, for each image, a file name, shooting date / time, tag, type, and the like are displayed as information. The “tag” item corresponds to a setting character string. The user can arbitrarily set a character string in the “tag” item in the editing operation. In this example, the user sets a character string representing the shooting location in the “tag” item. For example, the images G1, G2, and G3 are images taken in the same park, and the character string “A park” is set. The images G4 and G5 are images taken at the same observatory, and the character string “B observatory” is set. The “type” item displays “wide angle” or “narrow angle” as the type of angle of view of the image.

  The associating unit 15 refers to the set character string of the “tag” item of the first image on the basis of the first image selected by the user, for example, the image G1. The associating unit 15 compares the set character string of the first image with reference to the set character string of each narrow-angle image that is the other second image, and, for example, sets the character string that includes the same character string. Find the image you have. For example, the set character strings of the images G1, G2, and G3 are the same. The associating unit 15 determines that these images are images taken at the same shooting location and selects them as candidates for association.

  As a modification, the control unit 101 may automatically set a character string representing a shooting location at the time of imaging or the like without depending on a user operation. For example, the control unit 101 may determine a character string representing a shooting location based on the position information {latitude, longitude}. The control unit 101 may set a character string in the “file name” item of the image. For example, the control unit 101 may automatically assign a file name including a set character string according to a predetermined rule. Examples of file name rules include [shooting date and time] + [setting character string (shooting location)] + [individual sequence number].

  The above selection methods can also be applied in combination. For example, the condition of the shooting location of the first selection method and the shooting date condition of the second selection method may be combined. As the condition, for example, “up to the past one year at the same shooting location” can be designated.

[Association process (2)]
The second process in the associating process of the associating unit 15 is as follows. In the second process, the image selected as the candidate in the first process is determined to be associated using information on the shooting direction and the angle of view, and is associated according to the determination result. The associating unit 15 refers to the shooting direction and angle of view information in the metadata 22 or the management information 21 of each image file 24. As a condition, the associating unit 15 sets the shooting direction of the candidate image {azimuth angle θ, elevation angle φ within the range of the angle of view {horizontal angle of view Ah, vertical angle of view Av} of the wide-angle image that is the first reference image. } Is included. The associating unit 15 determines an image satisfying this condition as an image to be associated.

  In the example of FIG. 7 described above, the azimuth angle θ2 = 45 ° of the shooting direction 63b of the first narrow-angle image 6b is included in the range (−50 ° to + 70 °) of the horizontal field angle Ah1 of the wide-angle image 6a. And the azimuth angle θ3 = −20 ° in the shooting direction 63c of the second narrow-angle image 6c is included. Although not shown, the elevation angle φ2 = 0 ° in the shooting direction 63b of the first narrow-angle image 6b is included in the range (−40 ° to + 40 °) of the vertical angle of view Av1 of the wide-angle image 6a. The elevation angle φ3 = −10 ° in the shooting direction 63c of the two narrow-angle image 6c is included. Therefore, the first narrow-angle image 6b and the second narrow-angle image 6c are associated with the wide-angle image 6a.

  When associating the first image and the second image, the associating unit 15 may describe the association management information in the management information 21 as described above, or describe similar information in the metadata 22 of each image. May be.

[Video]
In the above description, the case of a still image has been mainly described. However, the present invention is basically applicable to a case of a moving image. When shooting a moving image, the imaging control unit 11 acquires the moving image data 23 by changing the electronic zoom magnification and the angle of view in a continuous shooting mode. The imaging control unit 11 describes information such as the electronic zoom magnification and the angle of view corresponding to the time point in the metadata 22 or the management information 21 for the moving image file 24. In addition, when playing and displaying a moving image, the display control unit 12 displays a mark or the like on the second screen in the second display mode, for example, corresponding to the position of the image frame at the start of the moving image or the image frame in the paused state. May be displayed.

[Effects]
As described above, according to the imaging device 1 and the display device 2 of Embodiment 1, it is easy to grasp the relationship between a plurality of images including wide-angle images and narrow-angle images, and better usability can be realized. On the display screen, the related narrow-angle image is automatically superimposed on the wide-angle image, so that the user can easily recognize a plurality of related images and intuitively understand it. Can be viewed. The user can recognize a narrow-angle image existing within the angle of view of the wide-angle image, and can browse quickly by referring to the associated narrow-angle image. The user can preferably browse a large number of images while switching the display mode.

  The following is given as a modification of the first embodiment. As a modification, the relationship between the angles of view may be relatively determined with respect to the type of image. That is, the imaging device 1 or the display device 2 refers to the angle of view in a plurality of images, and sets the image having the maximum angle of view as the first image that is a wide-angle image, and images other than the first image. Is a second image which is a narrow-angle image.

[Modification (1)-Second Display Mode]
FIG. 19 shows an example of the second screen in the second display mode in the imaging apparatus 1 according to the modification of the first embodiment. FIG. 19 corresponds to the specific example of FIG. In the display screen 401 of FIG. 19, a graphic representing the second image is not a mark but a transparent frame. For example, the transmission frame 9b represents the first narrow-angle image 6b, and the transmission frame 9c represents the second narrow-angle image 6c. The transparent frame has four sides of a rectangle displayed with lines and colors, and the inside thereof is a transparent region, and the first image portion in the background is displayed as it is. The size of the transparent frame area on the display is determined in accordance with the size of the angle of view of the second image. This makes it easier to grasp the relationship between the narrow-angle images in the wide-angle image.

  In the example of FIG. 19, first, the wide-angle image 6a is displayed on the display screen 401 at the reference position similar to that in FIG. 11, and then scrolled and enlarged / reduced based on the user operation. A state in which the angle of view range is moved and changed is shown. In FIG. 19, a point corresponding to (+ 15 °, + 10 °) in (azimuth angle, elevation angle) is arranged as the viewpoint position (Xa, Ya) of the wide-angle image 6a at the center point p1 of the display screen. . On the display screen 401, the range of 90 ° in the range of 120 ° of the horizontal angle of view of the wide-angle image 6a and the range of 60 ° in the range of 80 ° of the elevation angle are displayed in an enlarged manner. The position Xa is 15 ° in azimuth, and the position Ya is 10 ° in elevation. In the display screen 401, the right end position Xar corresponds to 60 °, the left end position Xal corresponds to −30 °, the upper end position Yat corresponds to 40 °, and the lower end position Yab corresponds to −20 °.

  The position coordinate (Xb, Yb) of the center point p2 of the transmission frame 9b corresponds to (+ 45 °, 0 °) in (azimuth angle, elevation angle). The horizontal width of the transmission frame 9b is a size corresponding to the horizontal angle of view Ah2 = 21 °, the azimuth angle is in the range of 45 ° ± 10.5 °, the left end position Xbl is + 34.5 °, and the right end position Xbr Is + 55.5 °. The vertical width of the transmission frame 9b is a size corresponding to the vertical angle of view Av2 = 14 °, the elevation angle is in the range of 0 ° ± 7 °, the upper end position Ybt is + 7 °, and the lower end position Ybb is −7 °. It is.

  Similarly, the position and size of the transmission frame 9c are determined. The position coordinates (Xc, Yc) of the center point p3 of the transmission frame 9c correspond to (−20 °, −10 °). The horizontal width of the transmission frame 9c is a size corresponding to the horizontal angle of view Ah3 = 21 °, the azimuth angle is in the range of −20 ° ± 10.5 °, the left end position Xcl is −30.5 °, and the right end is The position Xcr is −9.5 °. The vertical width of the transmission frame 9c is a size corresponding to the vertical angle of view Av3 = 14 °, the elevation angle is in the range of −10 ° ± 7 °, the upper end position Yct is −3 °, and the lower end position Ycb is −. 17 °.

  The display position {Xbr, Xbl, Ybt, Ybb} of the transmission frame 9b and the display position {Xcr, Xcl, Yct, Ycb} of the transmission frame 9c are obtained by the following equations when ignoring wide-angle distortion and distortion aberration. Note that the coefficient Kw and the coefficient Kh are used.

Xbr = (W / 2) −Kw (tan50 ° −tan55.5 °) (8)
Xbl = (W / 2) −Kw (tan 50 ° −tan 34.5 °) (9)
Kw = W / (tan50 ° + tan40 °) (10)
Ybt = (H / 2) −Kh (tan 40 ° −tan 7 °) (11)
Ybb = (H / 2) −Kh (tan 40 ° −tan (−7 °)) (12)
Kh = H / (tan 40 ° + tan 20 °) (13)
Xcr = (W / 2) −Kw (tan50 ° −tan (−9.5 °)) (14)
Xcl = (W / 2) −Kw (tan50 ° −tan (−30.5 °)) (15)
Yct = (H / 2) −Kh (tan 40 ° −tan (−3 °)) (16)
Ycb = (H / 2) −Kh (tan 40 ° −tan (−17 °)) (17)
In the example of FIG. 19, an example relating to the rotation angle of the image is indicated by a transmission frame 9e representing a narrow-angle image at the point p5. This narrow-angle image has an angle α with respect to the x direction.

  The display control unit 12 determines the size of the transmission frame using information on the shooting direction and angle of view of the image of the image data 23. The display control unit 12 determines the position and size of the transparent frame so as to correspond to the display state after the change when scrolling or enlargement / reduction corresponding to the viewpoint change in the display of the wide-angle image is performed.

  This modification has the advantage that the range and positional relationship of the narrow-angle image can be easily understood by displaying the transparent frame. As another modification, thumbnails may be displayed with the same size instead of the transparent frame.

[Modification (2)-Second display mode]
FIG. 20 shows an example of a display screen in the imaging apparatus 1 according to the modification of the first embodiment. The upper side of FIG. 20 shows an example of the first screen in the first display mode. In this first screen, thumbnails of wide-angle images and thumbnails of narrow-angle images are displayed in a list in a vertical and horizontal arrangement. At this time, the size of the thumbnail on the display is determined to be a vertical and horizontal size corresponding to the angle of view of the image. A wide-angle image thumbnail 2001 in this example is a panoramic image thumbnail having a large horizontal angle of view of 180 ° or more. A thumbnail 2002 of a narrow-angle image indicates a case where the thumbnail is an image having a horizontal angle of view of less than 180 °. Note that the number of images when arranged in parallel is variable such as two, three, four, etc. in one direction. The user can distinguish between the wide angle and the narrow angle based on the size of the thumbnail.

  The lower side of FIG. 20 shows an example of the second screen in the second display mode. The display screen 401 includes a main area 1001 and areas other than the main area 1001, in this example, a right-side area 1002 and a lower-side area 1003. In the main area 1001, a mark or the like of the second image is superimposed on the first image in the second display mode. When the entire first image cannot be displayed in the area 1001, a part of the angle of view is initially displayed with the shooting direction as the center point. In this example, a range corresponding to a part of the horizontal angle of view of the wide-angle image selected on the first screen is displayed in the area 1001. The user can change the display state of the first image in the region 1001 by scrolling, enlarging, reducing, or the like according to the viewpoint change or the like.

  As the graphic of the second image, a different graphic may be displayed according to a difference in image type, shooting date, and the like. In this example, circular, diamond, and star marks are shown as figures. As the image type, for example, a type corresponding to the difference in the angle of view may be set based on user settings or the like. Further, information may be given to the graphic for display. In this example, an identification number is assigned to the mark. In addition, an attribute value such as a shooting date and time based on the metadata 22 or the management information 21 may be displayed as information on the graphic, or only the attribute value may be displayed.

  In the area 1002 on the right side, information of all the plurality of second images associated with the first image, such as marks and attribute values, are displayed in parallel. In the area 1001, some of the marks of the second image are displayed according to the display state, and the marks of the other second images are not displayed. In the area 1002, information on the second image that is not displayed in the area 1001 is also displayed. When the mark of the second image is selected in the area 1001 or when the mark of the second image is selected in the area 1002, the transition to the third display mode may be performed. In the lower right area, a thumbnail of the second image selected last is displayed as a preview.

  A display mode, information on the first image, operation buttons, setting information, and the like are displayed in a lower area 1003. For example, information indicating that the current display mode is the second display mode and attribute values such as the shooting date and time of the first image are displayed. In addition, a button for switching between displaying and hiding the mark in the second display mode is provided. In the “ON” state, a mark is displayed, and in the “OFF” state, the mark is not displayed, that is, only the first image is displayed. In addition, a return button or the like for returning from the second display mode to the first display mode is provided.

  In addition, in the second screen of the second display mode, when there are a plurality of associated second images densely in the same position and the same region on the first image, individual marks One representative mark is displayed instead of overlapping. In this example, the representative mark is a star. When the user selects a representative mark, information on a plurality of second images associated with the position of the representative mark is displayed. In this case, as a method for displaying information on a plurality of second images, for example, a pop-up area 1005 is displayed on the first image, and information on the plurality of second images is displayed in the pop-up area 1005. When the user performs a selection operation on a desired second image from the pop-up area 1005, a transition is made to the third display mode in which the selected second image is displayed in detail.

  As another method, information on a plurality of second images associated with the representative mark may be displayed in the area 1002 or the like on the right side. As another method, a plurality of associated second images may be sequentially displayed in a predetermined area according to selection of a representative mark, that is, a slide show may be displayed. For example, when there are a plurality of images taken at the same place and in the same shooting direction at different shooting dates and times, these images can be linked and reproduced and displayed continuously.

  As another method, an area where a plurality of second images are densely displayed may be enlarged according to a representative mark selection operation so that the marks of the plurality of second images can be distinguished.

[Modification (3) -External Device Linkage]
The imaging device 1 and the display device 2 may store the image file 24 in an external device, or may read and reproduce the image file 24 from an external device. The imaging device 1 and the display device 2 may perform association processing for the image file 24 to be transmitted to an external device, and may transmit the image file 24 including the association information to the external device. In addition, the imaging device 1 and the display device 2 may perform association processing for the image file 24 received from an external device, and reproduce and display the image file 24 in a state of being associated based on the association information. That is, as an association method other than the first method and the second method described above, a method of performing association before transmitting the image file 24 to an external device, or a method of performing association after receiving the image file 24 from an external device. May be adopted. Further, when transmitting a plurality of image files 24 to an external device, the imaging device 1 and the display device 2 may describe angle-of-view information and association information as metadata 22 for each image file 24. It may be provided by being described in a management file different from the image file 24.

  For example, in the system of FIG. 1, the imaging apparatus 1 performs an association process on a plurality of captured images before transmitting them to the server 3, creates an image file 24 including an angle of view and association information, and creates a communication network 4. To the server 3 and stored in the image data DB. The imaging device 1 or the display device 2 accesses the server 3 through the communication network 4 and acquires the image file 24 from the image data DB of the server 3. In this case, a plurality of image files 24 can be acquired collectively by specifying, for example, a shooting date and time, a shooting location, etc. as a search condition. The imaging device 1 or the display device 2 reproduces and displays the acquired image data 23 of the plurality of image files 24 in an associated state based on the reference of the association information.

  In addition, for example, the imaging device 1 transmits the image file 24 including the angle of view and not including the association information to the server 3 and saving the image data DB in the image data DB without performing association processing for the plurality of captured images. The imaging device 1 or the display device 2 accesses the server 3 through the communication network 4 and acquires the image file 24 from the image data DB of the server 3. The imaging device 1 or the display device 2 performs association processing on the acquired plurality of image files 24, and reproduces and displays them in an associated state based on the angle of view and the association information.

  Further, the server 3 may perform association processing for a plurality of image data 23 in the image data DB. The server 3 performs the association process and stores it as an image file 24 including association information. The imaging device 1 or the display device 2 reproduces and displays the plurality of image files 24 acquired from the server 3 based on the association information reference.

  In addition, for example, the imaging device 1 performs association processing for a plurality of captured images, and transmits an image file 24 including an angle of view and association information to the display device 2. The display device 2 acquires the image file 24, and reproduces and displays the image data 23 of the acquired image file 24 in an associated state based on the reference of the association information.

  Further, for example, the imaging apparatus 1 transmits the image file 24 including the angle of view and not including the association information to the display apparatus 2 without performing association for the plurality of captured images. The display device 2 acquires the image file 24, performs association processing on the image data 23 of the acquired image file 24, and reproduces and displays the image data 24 in an associated state based on the association information.

  Further, the imaging device 1 and the display device 2 may read each image file 24 from a plurality of devices of the same user, and manage them by integrating them. For example, the first imaging device 1A and the second imaging device 1B in FIG. 1 each transmit the image file 24 of the captured image to the first display device 2A without associating. The first display device 2A performs association processing on these image files 24, and reproduces and displays them in the associated state.

  According to this modification, an association display function can be realized in a system in which a plurality of devices cooperate, and the user can realize association and storage of a large number of images.

[Variation (4)-Editing function]
As the imaging device 1 and the display device 2 of the modified example, an editing function is provided that allows the user to determine the association of a plurality of images and manually set and edit them. Using the editing function, the user can add, delete, or change an associated image on the display screen, and can change the display position of each image.

  FIG. 21 shows an example of the second screen in the second display mode in the imaging device 1 and the display device 2 of the modification. The following shows the case of the imaging device 1 having an editing function, but the same applies to the case of the display device 2 having an editing function. Based on user settings or input operations, it is possible to switch between an “ON” state in which editing is valid and an “OFF” state in which editing is invalid. When the imaging device 1 is in the “ON” state, the second screen in the second display mode associates the second image with the first image, the display position of the graphic of the second image, and the like based on the user input operation. Set to variable. The control unit 101 stores and manages the display position of the graphic of the second image as one of the metadata 22 or the management information 21. At the time of reproduction display, the control unit 101 refers to the information and determines the graphic display position.

  In this example, a case where a transparent frame is displayed as a graphic of the second image is shown. Initially, the imaging apparatus 1 automatically determines and displays the display position of the second image, as in the first embodiment. For example, a transmission frame 9b1 representing the first narrow-angle image 6b is displayed. The user touches the transparent frame 9b1 of the second image, for example, and moves it to a desired direction and position. The control unit 101 updates the display state so as to move the display position of the graphic according to the user operation. In this example, the state after movement of the transmission frame 9b1 is shown as a transmission frame 9b2. The center point of the first narrow-angle image 6b is the point p22 after movement from the point p21 before movement. The control unit 101 updates the management value so as to store the moved position of the graphic of the second image as a new display position.

  The control unit 101 may display information for confirming the change of the display position after the movement of the graphic of the second image and confirm with the user whether or not to change and save. For example, the control unit 101 displays a pop-up area near the moved position, and displays “The display position has been moved. Save / do not save” or the like. The user confirms this and presses a “save” button, for example. Thereby, the control part 101 preserve | saves the display position after a movement.

  In addition, the editing function includes a function of adding a second image to be associated and a function of releasing the association of the second image. In the case of addition, the user touches a desired position in the display screen, for example, the point p23 and designates addition. For example, the user can select the second image to be added by an add button in the pop-up area. The control unit 101 displays a graphic related to the selected second image at the position, and stores the display position of the second image in the management value.

  In the case of cancellation, the user selects the figure of the second image displayed in the display screen and designates cancellation. For example, the user touches the transparent frame 9c of the second narrow-angle image 6c and presses the release button in the pop-up area. The control unit 101 cancels the association of the second image for which cancellation is specified, deletes the display, and updates the management value.

  According to this modification, the editing function allows the user to freely edit the association display of the plurality of images in the second display mode so that the user can easily see and grasp the images.

The spherical surface 600 corresponding to the omnidirectional sphere has a first wide-angle image 6A, a second wide-angle image 6B, and a narrow-angle image 6C. The first wide-angle image 6A is a wide-angle image having a shooting range 2201 of 180 ° with a horizontal angle of view as viewed from the front camera side of the imaging device 1 in the front shooting direction (for example, northward). The second wide-angle image 6B is a wide-angle image having a shooting range 2202 of 180 ° in the horizontal angle of view as viewed from the rear camera side in the rear shooting direction (for example, southward). The narrow-angle image 6C is a narrow-angle image having a shooting range 2203 with a horizontal angle of view Ah in a desired shooting direction (for example, northward) from the front camera side. By combining the first wide-angle image 6A and the second wide-angle image 6B, an omnidirectional image that is a wide-angle image having a shooting range of 360 ° at a horizontal angle of view is formed. Although not shown, the same applies to the vertical angle of view Av. For example, the first wide-angle image 6A has a shooting range of 180 ° at the vertical angle of view.

[Imaging device]
FIG. 23 shows a configuration of a part related to the imaging unit 103 in the imaging apparatus 1. The imaging apparatus 1 includes a first imaging unit 103A, a second imaging unit 103B, and a third imaging unit 103C as the imaging unit 103, and these are connected to the interface circuit 131.

The lens unit 32a includes a first lens as a super-wide-angle lens that can capture the first wide-angle image 6A in the imaging range (ie, hemisphere) of 180 ° with the front horizontal and vertical angles of view. The second imaging unit 103B is an imaging unit corresponding to the rear camera, and includes a drive unit 31b and a lens unit 32b. The lens unit 32b includes a second lens as a super-wide-angle lens that can capture the second wide-angle image 6B in the imaging range of 180 ° (that is, a hemisphere) with the horizontal and vertical angle of view on the back.

  The third imaging unit 103C has the same configuration as that of the imaging unit 103 of Embodiment 1, and includes a drive unit 31c and a lens unit 32c. The lens unit 32c includes a third lens that can capture a narrow-angle image 6C within a set field angle range of less than 180 ° in the horizontal and vertical directions of the front surface. The angle of view at the time of imaging by the imaging unit 103C can be set based on a user operation within a predetermined range of angle of view of less than 180 °. For example, assume that a narrow-angle image 6C having a horizontal angle of view Ah of 50 ° is captured.

  The control unit 101 includes an omnidirectional imaging control unit 11A and an imaging control unit 11B. The omnidirectional imaging control unit 11A drives and controls the first imaging unit 103A and the second imaging unit 103B to capture an omnidirectional image. The omnidirectional imaging control unit 11A controls to capture the first wide-angle image 6A from the first imaging unit 103A and the second wide-angle image 6B from the second imaging unit 103B at the same timing. The omnidirectional imaging control unit 11A inputs and synthesizes the first wide-angle image 6A and the second wide-angle image 6B through the signal processing unit 132 and the like, thereby synthesizing the omnidirectional image having a 360 ° field angle range. Image.

  In addition, about the structure of the imaging part 103, the control part 101, etc. which contain the optical system which can image an omnidirectional image in this way, it is realizable using a well-known technique.

  The omnidirectional imaging control unit 11A stores the image data 23 of the captured omnidirectional image in the storage unit 102 as an image file 24 together with the metadata 22 including information such as the angle of view as in the first embodiment. To do. The imaging control unit 11B stores the image data 23 of the captured narrow-angle image in the storage unit 102 as the image file 24 together with the metadata 22 including information such as the angle of view as in the first embodiment.

  In the shooting mode of the imaging apparatus 1, it is possible to take an image using any imaging unit under the control of the control unit 101. Based on the control from the control unit 101, the imaging unit 103A, the imaging unit 103B, and the imaging unit 103C can simultaneously perform imaging at one time. Further, based on control from the control unit 101, the imaging unit 103A, the imaging unit 103B, and the imaging unit 103C can perform imaging at individual timings. An omnidirectional image can be photographed by simultaneous photographing and synthesis of the imaging unit 103A and the imaging unit 103B. Moreover, the hemisphere image by the 1st wide-angle image 6A or the 2nd wide-angle image 6B can be image | photographed by imaging | photography using one of the imaging part 103A and the imaging part 103B. Moreover, simultaneous imaging with one of the imaging unit 103A or the imaging unit 103B and the imaging unit 103C is also possible. In that case, the shooting date and time of the one wide-angle image and the narrow-angle image 6C are the same and can be automatically associated. The control unit 101 may add information such as the type representing the omnidirectional image, the hemispherical image, or the narrow-angle image 6C to the metadata 22 or the management information 21 of the captured image. The control unit 101 may give association information to the metadata 22 or the like for a plurality of images that have been taken simultaneously.

[Imaging device-appearance]
FIG. 24 shows the appearance of an implementation example of the imaging apparatus 1. In this example, the case where it is a smart phone as the imaging device 1 is shown. 24 shows the front camera side of the housing 2400 of the imaging apparatus 1, and the right side shows the rear camera side. On the front camera side, a first lens 2401 is provided at a predetermined position of the housing 2400, and a third lens 2403 is provided at a predetermined position. On the rear camera side, a second lens 2402 is provided at a predetermined position on the opposite side corresponding to the position of the first lens 2401 on the front camera side. On the rear camera side, a display screen 2404 of the display device 104, operation buttons 2405, and the like are provided.

[Display screen-second display mode]
FIG. 25 shows an example of the second screen in the second display mode in the second embodiment. The first screen in the first display mode is the same as that in the first embodiment, and can display a list of information on the omnidirectional images and narrow-angle images. When the omnidirectional image is selected and operated on the first screen in the first display mode, the display control unit 12 displays the second screen in the second display mode as shown in FIG.

  The display control unit 12 displays an omnidirectional image as indicated by a circular area 2500 in the second screen. The display control unit 12 first displays the region 2500 in a display state in which the shooting direction (azimuth angle and elevation angle, for example, northward in FIG. 22) of the omnidirectional image is located at the center point p0. For area 2500, operations such as scrolling and enlarging / reducing can be performed so as to change the display state corresponding to the viewpoint change in accordance with the user's touch input operation or the like. For example, when the user swipes leftward in the region 2500, the display state in the region 2500 is updated so that the viewpoint in the omnidirectional image moves in the right direction, that is, in the positive direction at the horizontal angle of view. Is done. The control unit 101 performs image processing for changing the display state at that time. Note that image processing for changing the display state of the omnidirectional image is a known technique. In particular, the viewpoint position in the initial display state of the omnidirectional image may be 0 °, that is, the horizontal direction, or 90 °, that is, the zenith direction.

  When there is a narrow-angle image associated with the omnidirectional image, the control unit 101 displays the narrow-angle image on the omnidirectional image region 2500 as a predetermined figure or Display as a reduced image. In this example, a case of displaying with a transparent frame is shown. A case where three narrow-angle images are associated on the omnidirectional image region 2500 is shown. Point p11 has a transmission frame 2501 representing the first narrow-angle image, point p12 has a transmission frame 2502 representing the second narrow-angle image, and point p13 represents the third narrow-angle image. A transmission frame 2503 is included. Along with the change of the display state in the area 2500 of the omnidirectional image, the position, shape, size, etc. of the figure of the narrow-angle image are also changed. Note that the narrow-angle image region corresponding to the transmission frame is arranged in the spherical surface of the omnidirectional sphere, and therefore has a shape that is distorted in the circumferential direction, that is, has an arc portion. In this example, the transparent frame is simply displayed as a rectangle.

  Further, as in the first embodiment, based on a predetermined operation on the second screen in the second display mode, on / off switching of the display of the graphic of the narrow-angle image, an operation for returning to the first display mode, and the like are also possible. Is possible. When a graphic representing a narrow-angle image is selected and operated on the second screen, the control unit 101 displays the narrow-angle image in detail in the third display mode, as in the first embodiment.

[Effects]
According to the second embodiment, when displaying an omnidirectional image as a wide-angle image, a narrow-angle image having a predetermined relationship such as the same shooting location is displayed in association with each other, so the user grasps the relationship between a plurality of images. Easy browsing and suitable browsing.

  The following is possible as a modification of the second embodiment. The second imaging unit 103B on the rear camera side may be omitted, and the first imaging unit 103A may be used to capture a hemispherical image having a forward 180 ° field angle range.

  On the second screen in the second display mode, the omnidirectional image area 2500 may be converted into a rectangular area instead of a circle. In the rectangular area, an image corresponding to a part of the field angle range of the omnidirectional image is displayed, and the display state is changed based on a user operation.

  The imaging device 1 may capture an omnidirectional image in its own device, capture a narrow-angle image captured by an external device, and perform association display. Conversely, the imaging device 1 may capture a narrow-angle image within its own device, capture an omnidirectional image captured by an external device, and perform association display. For example, the second imaging device 1B in FIG. 1 captures an omnidirectional image and acquires a narrow-angle image captured by the first imaging device 1A or a narrow-angle image registered in the server 3 in its own device. Then, the association display may be performed.

  Note that an image having an angle of view of 360 ° has an omnidirectional angle of view regardless of the shooting direction of the camera. For this reason, it is not always necessary to change the display direction in the display screen according to the shooting direction. Therefore, when the moving image of the omnidirectional image is reproduced and displayed in the second display mode or the third display mode, the following two types of display methods may be selected. First, similar to the reproduction display of the narrow-angle image, the image that changes according to the shooting direction at the time of shooting is reproduced and displayed as it is. Alternatively, secondly, based on the information on the shooting direction recorded as metadata at the time of moving image shooting, for example, it is rotated by an angle corresponding to the azimuth angle so that the image direction is fixed regardless of the shooting direction. , Play and display in that fixed direction.

  Moreover, when displaying an image regardless of whether it is a moving image or a still image, the direction of the imaging device 1 (the same applies to the display device 2) is detected using the shooting direction measurement unit 111 and the position detection unit 113, and the detected direction is detected. May be displayed so that the image capturing direction matches the image capturing direction.

(Embodiment 3)
The imaging device and display device according to Embodiment 3 of the present invention will be described with reference to FIG. Hereinafter, a different part from the structure of Embodiment 1 in the structure of Embodiment 3 is demonstrated. In the imaging apparatus 1 according to the third embodiment, a specific shooting mode for associating a plurality of images is provided.

[Shooting mode]
The imaging apparatus 1 according to the third embodiment has a first shooting mode that is a normal shooting mode and a second shooting mode for performing association as shooting modes. The imaging device 1 switches the shooting mode based on a user input operation or a user setting. The user performs a predetermined operation for switching between the first shooting mode and the second shooting mode at an arbitrary timing through the operation input unit 105 or the like. The predetermined operation may be, for example, pressing of a mode switching button.

  FIG. 26 shows switching of shooting modes on the time axis in the imaging apparatus 1 according to the third embodiment. The imaging apparatus 1 is initially in the state of the first shooting mode, and does not perform association processing for individual images captured in the first shooting mode. For example, the image captured at time t11 is not associated, and the association information is not described in the metadata 22 or the like.

  The user performs an operation of switching from the first shooting mode to the second shooting mode at a desired timing, for example, at time T2. In the state of the second shooting mode, the imaging device 1 performs a process of automatically associating each image captured during that period. For example, images are captured at time points t1 to t4 in the second shooting mode. The control unit 101 uses the associating unit 15 to perform associating processing on these images and describes the associating information in the metadata 22 or the management information 21. At that time, the associating unit 15 associates the plurality of images as a group. In this example, the images at time points t1 to t4 are associated as the first group. The associating unit 15 describes the group identification information as one of the metadata 22 or the management information 21. The group identification information may be, for example, a character string using the start date / time and end date / time of the second shooting mode period, or a character string using the number of occurrences of the second shooting mode. In addition, the file names and metadata 22 of these images may be provided with a character string that is a combination of the group identification information and the shooting date and sequence number of each individual image.

  The user performs an operation of switching from the second shooting mode to the first shooting mode at a desired timing, for example, at time T4. The imaging device 1 does not associate individual images captured in the first imaging mode, for example, images captured at time t12. The control unit 101 may execute the association process when returning to the first imaging mode.

  In addition, the associating unit 15 determines the type of wide-angle image and narrow-angle image for a plurality of images captured during the period of the second shooting mode. The association unit 15 does not perform association when only one of the wide-angle image and the narrow-angle image exists. When both the wide-angle image and the narrow-angle image exist, the associating unit 15 associates the second image that is the narrow-angle image with the first image that is the wide-angle image.

  At the time of reproduction display, the display control unit 12 confirms the association based on the reference of the group identification information or the like in the image file 24 or the management information 21 and displays the association.

[Effects]
According to the third embodiment, it is easy for the user to switch the shooting mode and perform association by his / her own judgment. The third embodiment corresponds to an embodiment in which the determination regarding the shooting date and time of the second selection method is automated using a specific shooting mode.

  The following is possible as a modification of the third embodiment. The imaging device 1 automatically switches the shooting mode according to the determination. The imaging device 1 determines the type of angle of view of an image, for example, a distinction between a wide angle and a narrow angle at the time of imaging. The imaging device 1 automatically switches from the first shooting mode to the second shooting mode when the captured image is a wide-angle image. The imaging device 1 determines the narrow-angle image captured in the second shooting mode, and associates the narrow-angle image with the first wide-angle image. The imaging apparatus 1 returns from the second shooting mode to the first shooting mode when, for example, a predetermined time based on the setting elapses after entering the second shooting mode.

  Although the present invention has been specifically described above based on the embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention.
