A communication unit or the like may be provided.

  Next, processing performed by the imaging apparatus 1 according to the first embodiment will be described. FIG. 4 is a flowchart illustrating an outline of processing performed by the imaging apparatus 1.

  In FIG. 4, the case where the imaging device 1 is set to the shooting mode (step S <b> 101: Yes) will be described. In this case, the display control unit 95 causes the display unit 6 to display a live view image corresponding to the front image data that the imaging unit 2 continuously generates at a minute time interval (step S102).

  FIG. 5 is a diagram illustrating a situation when the photographer photographs using the imaging apparatus 1. FIG. 6 is a diagram showing one representative image W1 among the live view images that the display unit 6 sequentially displays in time series under the situation shown in FIG. When taking a family photo as shown in FIGS. 5 and 6, the photographer K1 (dad) photographs the subject K2 (mother) and the subject K3 (child) while viewing the live view image W1 in FIG. 6, for example. Determine the composition of the moment.

  Subsequently, when a release signal is input by operating the release switch 42 (step S <b> 103: Yes), the imaging device 1 controls the front image data generated by the imaging unit 2 under the control of the control unit 9. Is acquired (step S104).

  Thereafter, the control unit 9 determines whether or not the sub-image simultaneous storage mode for acquiring the sub-image data by activating the rear imaging unit 5 in the imaging device 1 is set (step S105). When the control unit 9 determines that the sub-image simultaneous storage mode is set in the imaging apparatus 1 (step S105: Yes), the imaging apparatus 1 proceeds to step S106 described later. On the other hand, when the control unit 9 determines that the sub-image simultaneous storage mode is not set in the imaging device 1 (step S105: No), the imaging device 1 proceeds to step S111 described later.

  In step S <b> 106, the imaging device 1 acquires the sub image data generated by the rear imaging unit 5 under the control of the control unit 9. For example, as illustrated in FIG. 7, the imaging device 1 acquires a sub-image W2 in which the photographer K1 is captured as a sub-image corresponding to the sub-image data generated by the rear imaging unit 5.

  Subsequently, the image association unit 96 creates an image file in which the sub-image data is associated with the front image data, and stores the created image file in the image data storage unit 81 (step S107).

  Thereafter, the display control unit 95 causes the display unit 6 to display a front view corresponding to the acquired front image data on the display unit 6 for a predetermined time (for example, 3 seconds) (step S108). Note that the display control unit 95 may display the sub image corresponding to the sub image data on the display unit 6 for a predetermined time (for example, 3 seconds).

  Subsequently, the control unit 9 determines whether or not the power supply of the imaging apparatus 1 is in an off state by operating the power switch 41 (step S109). When the control unit 9 determines that the power of the imaging device 1 is off (step S109: Yes), the imaging device 1 ends this process. On the other hand, when the control unit 9 determines that the power supply of the imaging apparatus 1 is not in the off state (step S109: No), the imaging apparatus 1 proceeds to step S110.

  In step S110, when a mode switching signal is input from the shooting mode switching switch 43, the control unit 9 accepts a shooting / playback mode switching operation in accordance with the mode switching signal, while the mode is switched via the shooting mode switching switch 43. When no switching signal is input, the current mode is maintained. After step S110, the imaging apparatus 1 returns to step S101.

  In step S103, when a release signal is not input via the release switch 42 within a predetermined time (for example, 2 seconds) (step S103: No), the imaging apparatus 1 proceeds to step S109.

  A case where the control unit 9 determines that the sub-image simultaneous storage mode is not set in the imaging apparatus 1 in step S105 (step S105: No) will be described. In this case, the control unit 9 stores the front image data acquired from the imaging unit 2 in the image data storage unit 81 (step S111). Thereafter, the imaging apparatus 1 proceeds to step S108.

  Next, the case where the imaging apparatus 1 is not set to the shooting mode (step S101: No) and is set to the reproduction mode (step S112: Yes) will be described. In this case, the display control unit 95 causes the display unit 6 to display a list of reduced images (thumbnail images) obtained by reducing the images corresponding to the image data of each image file stored in the image data storage unit 81 (step S113).

  Subsequently, when a reduced image of the image file to be enlarged and displayed is selected via the operation input unit 4 or the touch panel 7 (step S114: Yes), the control unit 9 includes the front image data in the selected image file. And sub-image data are stored (step S115). When the control unit 9 determines that the front image data and the sub image data are stored in the selected image file (step S115: Yes), the imaging device 1 proceeds to step S116 described later. On the other hand, when the control unit 9 determines that the front image data and the sub image data are not stored in the selected image file (step S115: No), the imaging device 1 proceeds to step S125 described later.

  In step S <b> 116, the trimming unit 93 generates a face image by cutting out from the sub-image a face area that partially includes the face of the subject detected by the face detection unit 92 from the sub-image. Specifically, as illustrated in FIG. 7, the trimming unit 93 generates a face image by cutting out from the sub-image W2 a face area that partially includes the face of the subject K1 detected by the face detection unit 92 from the sub-image W2. To do.

  Subsequently, the image composition unit 94 reflects the positional relationship between the subject imaged in the front image and the sub-image when the face image of the subject K1 generated by the trimming unit 93 is viewed centering on the imaging device 1 at the time of photographing. A synthesized image is generated by synthesizing with the display area of the front image that has been made (step S117).

  FIG. 8 schematically illustrates the positional relationship between the subject imaged in the front image and the sub-image when viewed from the imaging device 1 that is referred to when the image composition unit 94 composes the face image with the front image. FIG. 9 is a plan view in the direction of arrow A in FIG. In FIG. 8, a region W <b> 1 indicated by a dotted line indicates a shooting region of the imaging unit 2, and a region W <b> 2 indicated by a dotted line indicates a shooting region of the rear imaging unit 5.

  As shown in FIG. 8 and FIG. 9, when compositing the face image with the front image W1, the image composition unit 94 appears in the front image and the sub-image when viewed mainly with the imaging device 1 at the time of photographing. The face image is combined with the display area of the front image reflecting the positional relationship of the subject. For example, when the face of the subject K1 is shown on the left side of the sub-image W2 as in the situation shown in FIG. 7, the image composition unit 94 virtually rotates the imaging unit 2 around the imaging device 1 (arrows). (A)), the face image A1 is combined with the display area of the front image W1 in which the subject K1 is virtually shown in the front image W1 (see FIGS. 8 and 9). Specifically, as illustrated in FIG. 10, the image composition unit 94 generates a composite image W3 by compositing the face image A1 in the vicinity of the right end portion of the front image W1.

  After step S117, the display control unit 95 causes the display unit 6 to display the combined image W3 combined by the image combining unit 94 (step S118).

  Subsequently, the control unit 9 determines whether or not a slide operation has been performed on the face image A1 in the composite image W3 displayed by the display unit 6 (step S119). When the control unit 9 determines that the slide operation has been performed on the face image A1 (step S119: Yes), the display control unit 95 focuses on the imaging device 1 at the time of shooting according to the locus of the slide operation by the user. In this state, the composite image W3 is switched to the sub-image W2 and displayed on the display unit 6 in a state reflecting the positional relationship of the subject shown in the front image W1 and the sub-image W2 (step S120).

  FIG. 11 is a diagram for schematically explaining switching from the composite image W4 to the sub-image W2 by the display control unit 95. As shown in FIG. 11, the display control unit 95 displays at least a part of the sub-image W2 while gradually increasing the display area of the sub-image W2 from the left end according to the locus of the slide operation on the face image A1. Then, the display area of the composite image W3 is displayed while gradually decreasing from the left end (FIG. 11 (a) → FIG. 11 (b)). Thereby, the display control unit 95 can smoothly perform screen transition from the direction reflecting the positional relationship of the subject that appears in the front image and the sub-image when viewed with the imaging device 1 as the center at the time of shooting.

  After step S120, the control unit 9 determines whether or not the user has lifted his / her finger from the face image A1 (step S121). When the control unit 9 determines that the user has lifted his / her finger from the face image A1 (step S121: Yes), the display control unit 95 displays the subject that appears in the front image and the sub-image when viewed with the imaging device 1 as the center. The sub image W2 is switched to the composite image W3 in a state where the positional relationship is reflected (step S122). Specifically, the display control unit 95 displays the display area of the sub-image W2 while reducing the display area so as to move instantaneously from the right end of the display screen of the display unit 6. Thereafter, the imaging apparatus 1 proceeds to step S123. On the other hand, when the control unit 9 determines that the user moves on the display screen while maintaining the touch on the face image A1 (step S121: No), the imaging device 1 continues this determination.

  In step S123, the control unit 9 determines whether an image switching operation has been performed. Specifically, the control unit 9 determines whether or not a switching signal for switching another image is input from the operation input unit 4. When the control unit 9 determines that an image switching operation has been performed (step S123: Yes), the imaging device 1 proceeds to step S124. On the other hand, when the control unit 9 determines that an image switching operation is not performed via the operation input unit 4 (step S123: No), the imaging device 1 returns to step S119.

  In step S124, the control unit 9 determines whether or not the imaging device 1 is set to the reproduction mode. When the control unit 9 determines that the imaging device 1 is set to the reproduction mode (step S124: Yes), the imaging device 1 returns to step S113. On the other hand, when the control unit 9 determines that the imaging device 1 is not set to the reproduction mode (step S124: No), the imaging device 1 proceeds to step S109.

  In step S119, when the control unit 9 determines that the slide operation is not performed on the face image A1 (step S119: No), the imaging device 1 proceeds to step S123.

  In step S115, when the control unit 9 determines that the sub image data is not stored in the selected image file (step S115: No), the display control unit 95 displays all the front images corresponding to the front image data. The image is enlarged and displayed on the display unit 6 (step S125). Thereafter, the imaging apparatus 1 proceeds to step S124.

  A case where no image file is selected in step S114 (step S114: No) will be described. In this case, the control unit 9 determines whether or not a predetermined time (for example, 5 seconds) has elapsed (step S126). When the control unit 9 determines that the predetermined time has elapsed (step S126: Yes), the imaging device 1 proceeds to step S109. On the other hand, when the control unit 9 determines that the predetermined time has not elapsed (step S126: No), the imaging device 1 returns to step S114.

  The omnidirectional imaging unit 300 having the above configuration condenses light from the visual field region around the entire circumference around the optical axis L3, and after the collected light is photoelectrically converted by an imaging device (not shown), a predetermined value is obtained. The omnidirectional image data having an annular shape is generated by performing A / D conversion by performing the above signal processing. The omnidirectional imaging unit 300 outputs omnidirectional image data to the control unit 500 via the communication unit 400. The detailed configuration of the omnidirectional imaging unit 300 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-243690. The omnidirectional imaging unit 300 is connected to the imaging apparatus 200 via the communication unit 400. Furthermore, in the second embodiment, the omnidirectional imaging unit 300 functions as a second imaging unit.

For example, as illustrated in FIG. 23, the imaging apparatus 200 acquires an omnidirectional image W21 corresponding to the omnidirectional image data generated by the omnidirectional imaging unit 300. In the omnidirectional image W21, subjects K1 to K3 are shown in an annular shooting region.

  Subsequently, the image conversion unit 501 converts the shape of the omnidirectional image W21 from an annular shape to a belt shape to generate a converted image (step S204). Specifically, as shown in FIG. 23, the image conversion unit 501 generates a converted image by converting the image into a band-shaped image by cutting from a predetermined position of the omnidirectional image W21, for example, the cut line C. The position where the image conversion unit 501 cuts from the omnidirectional image W21 can be set as appropriate. Furthermore, when the detection result of the face detection unit 92, for example, the subject K3 is detected from the front image W30 and the omnidirectional image W21, the image conversion unit 501 cuts out the subject K3 so that it is displayed at the center of the converted image. Good.

In this case, the display control unit 95 causes the display unit 6 to display the live view image corresponding to the front image data that the imaging unit 2 continuously generates at a minute time interval (step S215). Thereafter, the imaging apparatus 200 proceeds to step S207.

  A case where the control unit 500 determines in step S209 that the sub-image simultaneous storage mode is not set in the imaging apparatus 200 (step S209: No) will be described. In this case, the control unit 500 creates an image file storing the front image data acquired from the imaging unit 2 and stores the image file in the image data storage unit 81 (step S216). Thereafter, the imaging apparatus 200 proceeds to step S212.

  Next, the case where the imaging apparatus 1 is not set to the shooting mode (step S201: No) and is set to the reproduction mode (step S217: Yes) will be described. In this case, the display control unit 95 causes the display unit 6 to display a list of reduced images obtained by reducing the images corresponding to the image data of each image file stored in the image data storage unit 81 (step S218).

  Subsequently, when the reduced image of the image file to be enlarged and displayed is selected via the operation input unit 4 or the touch panel 7 (step S219: Yes), the control unit 500 includes the front image data in the selected image file. And omnidirectional image data as sub-image data are stored (step S220). When the control unit 500 determines that front image data and omnidirectional image data as sub-image data are stored in the selected image file (step S220: Yes), the imaging apparatus 200 performs step S221 described later.
