  FIG. 2 shows the transition of the overall display screen 300 executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) to represent the embodiment of the present invention.

The display screen of (1) shows a state in which a live view video (through image) before the zoom-up operation to the optical zoom lens is displayed. Here, the image displayed on the full screen is an image 301 photographed by the first imaging means.
Note that the display control shown in (1) is performed by the processing in step S104 in FIG.

  The display screen of (2) shows a state in which a live view image is displayed after the zoom-up operation to the optical zoom lens is operated. Here, the video 303 obtained by the second imaging means is displayed outside the boundary frame 302, and the video 301 obtained by the first imaging means is displayed inside the boundary frame 302. Furthermore, a boundary frame 302 is displayed between the display range of the video image captured by the second imaging unit and the display range of the video image captured by the first imaging unit. .

In other words, in this state, the video 303 acquired by the digital zoom lens is displayed on one screen, and the video 303 acquired by the optical zoom lens is acquired inside a part of the video shooting region 302 of the video 303 to be displayed. A video 301 having the same shooting area (viewing angle) as the video is displayed on one screen 300 (display control means). Thus, the image before the zoom-up operation is displayed outside the boundary frame 302 as the image 303 obtained by the second imaging unit, and the image after the zoom-up operation is displayed inside the boundary frame 302. By displaying the image 301 obtained by the first imaging means, the surrounding image 303 can be confirmed in the live view image even after zooming up to the optical zoom lens.
Note that the display control shown in (2) is performed by the processing in step S105 in FIG.

In the display screen of (3), the time is elapsed from the state of the display screen of (2), and the subject (automobile) has moved into the video 303 obtained by the second imaging means, so that the subject is new. It shows the detected state. Note that a subject frame 304 is displayed for a newly detected subject.
The display control shown in (3) is performed by the process in step S107 in FIG.

  In the display screen of (4), the subject (automobile) has moved into the video 301 obtained by the first imaging means after a further time has elapsed from the state of the display screen of (3), so that the subject is It shows a state where it is recognized that it is inside the boundary frame 302.

That is, here, it is determined whether or not the subject has moved from the image outside the part of the shooting area acquired by the digital zoom lens to the image within the part of the shooting area acquired by the optical zoom lens (movement determination means). ).
Here, the image displayed on the full screen is automatically switched to the image 301 photographed by the first imaging means.

  In other words, when the movement determining means determines that the subject has moved, control is performed so that an image including the moved subject within a part of the shooting area acquired by the optical zoom lens is displayed on a single screen. (Full-screen display control means).

Further, at this time, since the zoom position of the optical zoom lens has already been set to a user-desired position after the zoom-up operation to the optical zoom lens has been operated, the image 301 obtained by the first imaging unit is here. Can be recorded in a state in which the angle of view is stable while the zoom position is fixed.
Note that the display control shown in (4) is performed by the processing in step S104 in FIG.
FIG. 3 will be described.

FIG. 3 is a flowchart showing the flow of overall processing executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) to represent the embodiment of the present invention.
Note that the flowchart of FIG. 3 is executed only when the execution permission of the flowchart of FIG. 3 is set.

In step S101, the imaging apparatus 100 displays the live view video (through image) before the zoom up operation to the optical zoom lens is displayed on the display screen of (1). It is determined whether any one of the zoom operation or the zoom operation to the first imaging unit is instructed. If it is determined that a zoom operation has been instructed (yes), the process proceeds to step S102. If it is determined that a zoom operation has not been instructed (no), the process proceeds to step S104.
In step S102, the imaging apparatus 100 first automatically adjusts the zoom setting of the second imaging unit so that the angle of view of the second imaging unit is the same as the angle of view of the first imaging unit.

  Next, the first image pickup means zoom-up amount (for example, 2 times) after the zoom operation to the tele side is acquired and compared with the first image pickup means zoom amount (for example, 1 time) before the zoom operation. The video 303 acquired by the digital zoom lens is displayed on one screen, and the video and the shooting area (images acquired in the part of the shooting area 302 acquired by the optical zoom lens are inside the part of the shooting area 302 of the video 303 to be displayed. A range in which the video 301 having the same angle) is displayed is calculated using a relative ratio before and after the zoom operation of the first imaging unit toward the tele side.

Alternatively, the second image pickup means zoom-down amount (for example, 0.5 times) after the zoom operation to the wide side is acquired and compared with the second image pickup means zoom amount (for example, 1 time) before the zoom operation. A video 303 acquired by the digital zoom lens is displayed on one screen, and a video and a shooting area acquired in a part of the shooting area 302 acquired by the optical zoom lens inside a part of the shooting area 302 of the video 303 to be displayed. A range in which the video 301 having the same (viewing angle) is displayed is calculated using a relative ratio before and after the zoom operation to the wide side of the second imaging unit.
The detailed processing flow performed in step S102 will be described with reference to FIGS.

  In step S <b> 103, the imaging apparatus 100 determines whether a subject is detected within the imaging range of the first imaging unit. If it is determined that the subject is detected within the shooting range of the first imaging means (yes), the process proceeds to step S104, and the subject is not detected in the shooting range of the first imaging means. If it is determined that (No), the process proceeds to step S105.

That is, when it is determined that the subject is detected within the shooting range of the first imaging unit (Yes), the subject (in the video 301 obtained by the first imaging unit as described above) The car is moving.
In step S104, the imaging apparatus 100 displays the image of the first imaging unit on the display screen in full screen.

  In step S105, the imaging apparatus 100 displays a video image of the second imaging unit and a boundary frame 302 representing the imaging range of the first imaging unit calculated in step S102 on the screen.

  In step S <b> 106, the imaging apparatus 100 determines whether an object that is a subject is detected within the range of the second imaging unit. If it is determined that the subject is detected within the shooting range of the second imaging means (yes), the process proceeds to step S107, and the subject is not detected within the shooting range of the second imaging means. If it is determined (No), the process proceeds to step S108.

That is, when it is determined that the subject is detected within the shooting range of the second imaging unit (Yes), the subject (in the video 303 obtained by the second imaging unit as described above) The car is moving.
In step S107, the imaging apparatus 100 displays a subject frame 304 around the subject newly detected in step S106.

In step S108, the imaging apparatus 100 determines whether or not a moving image is currently being recorded (capturing). If it is determined that a movie is already being recorded (yes), the process proceeds to step S109. If it is determined that a movie is not currently being recorded (no), the process proceeds to step S110.
In step S109, the imaging apparatus 100 continues recording the video of the first imaging unit.

  In step S110, the imaging apparatus 100 determines whether the recording shutter button has been pressed. If it is determined that the recording shutter button has been pressed (Yes), the process proceeds to step S111. If it is determined that the recording shutter button has not been pressed (No), the process returns to Step S101.

In step S <b> 111, the imaging apparatus 100 performs processing when the recording shutter button is pressed to perform processing according to the situation. The detailed processing flow performed in step S111 will be described with reference to FIG.
FIG. 4 will be described.

  FIG. 4 shows a zoom operation performed by the first image pickup means (optical zoom lens) executed by the system control unit 112 of the image pickup apparatus 100 or the CPU of the image pickup apparatus 100 (not shown) to represent the embodiment of the present invention. It is the flowchart (right figure) which shows the transition (left figure) of the screen displayed, and the flow of the process at that time.

  When each zoom operation is performed by the first imaging unit (S201), the imaging apparatus 100 updates the size of the boundary frame 302 of the first imaging unit in the video of the second imaging unit. The boundary frame 302 of the first imaging unit is recalculated (S203). The calculation method at this time is the same as the calculation method described in S102 in FIG. After the new boundary frame 302 after the zoom operation is calculated, the boundary frame 302 on the screen is updated to a new range (S204). Every time it is determined that each zoom operation has been performed (S202: Yes), the boundary frame 302 is recalculated and the displayed boundary frame 302 is updated. When the zoom operation is performed by the first imaging unit, the entire shooting range of the image displayed on the screen is not changed, and only the size of the frame representing the shooting range of the first imaging unit is changed.

  The example of the display screen of (5) represents a screen display when the zoom-up operation is performed on the tele side. In the video displayed on the screen, the display range 303 of the second imaging unit is enlarged, and the display range 301 of the first imaging unit is reduced. That is, when the zoom instruction to the optical zoom lens is received (first receiving means) and the zoom instruction to the tele side is received, the optical zoom lens is displayed in one screen displayed by the display control means. The area in which the image within the part of the shooting area acquired by (1) is displayed is reduced, and the area in which the image outside the part of the shooting area acquired by the digital zoom lens is displayed is enlarged (area adjustment). means).

In the example of the display screen (6), a screen display when the zoom-down operation is performed on the wide side is shown. In the video displayed on the screen, the display range 303 of the second imaging unit is reduced and the display range 301 of the first imaging unit is enlarged. Conversely, when an instruction for zooming to the wide side is received, the area adjustment unit enlarges an area in which a video in a part of the shooting area acquired by the optical zoom lens is displayed in one screen. In addition, a region where an image outside a part of the photographing region acquired by the digital zoom lens is displayed is reduced.
FIG. 5 will be described.

  FIG. 5 is displayed when zoom operation is performed with the second imaging unit (digital zoom lens) executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) to represent the embodiment of the present invention. It is the flowchart (right figure) which shows the transition (left figure) of the screen to be performed, and the flow of the process at that time.

  When the zoom operation is performed by the second imaging unit (S301), the imaging apparatus 100 updates the size of the boundary frame 302 of the first imaging unit in the video of the second imaging unit. Recalculates the boundary frame 302 of the first imaging means (S303). The calculation method at this time is the same calculation as S102 in FIG. After the new boundary frame 302 after the zoom operation is calculated, the imaging range of the second imaging means displayed on the screen is updated to a new range (S304). After the imaging range is updated, the boundary frame 302 of the first imaging unit on the screen is updated to a new range (S305). Each time it is determined that the zoom operation has been performed (S302: Yes), the imaging range of the second imaging unit is updated and the imaging range frame of the first imaging unit is recalculated. Update. When the zoom operation is performed by the second image pickup unit, the shooting range of the image displayed on the screen and the size of the shooting range frame of the first image pickup unit change simultaneously. Since there is no change in the zoom amount of the first imaging means, there is no change in the actually captured video.

  The display screen example (7) represents a screen display when the zoom-down operation is performed on the wide side. In the video displayed on the screen, the display range 303 of the second imaging unit is enlarged and the display range 301 of the first imaging unit is reduced.

  In other words, when the zoom instruction to the digital zoom lens is received (second receiving means) and the zoom instruction to the wide side is received by the second receiving means, the area adjusting means The area where the image within the part of the shooting area acquired by the optical zoom lens is displayed is reduced, and the area where the image outside the part of the shooting area acquired by the digital zoom lens is displayed is enlarged and displayed.

  The example of the display screen of (8) represents a screen display when a zoom-up operation is performed on the tele side. In the video displayed on the screen, the display range 303 of the second imaging unit is enlarged, and the display range 301 of the first imaging unit is reduced. The adjustment means enlarges the area where the image within the part of the shooting area acquired by the optical zoom lens is displayed on one screen, and displays the image outside the part of the shooting area acquired by the digital zoom lens. The displayed area is reduced and displayed.

  FIG. 6 shows an operation example when the subject frame 304 is changed. When the subject frame 304 is automatically selected by the conventional function, the subject frame 304 is changed to a desired subject by a touch operation on the screen. The subject frame 304 may be changed to a desired subject by operating a button such as a cross key.

  FIG. 7 is a flowchart illustrating a process flow when the shutter button executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) is pressed to represent the embodiment of the present invention. In the processing when the shutter button is pressed, it is first determined whether or not the current moving image shooting mode is set (S401). If it is not in the moving image shooting mode, the video of the first imaging means is recorded (S403), and the process is terminated. If it is in the movie shooting mode, it is determined whether or not movie shooting is currently being performed (S402). If it is not during moving image shooting, the CPU starts recording the video of the first imaging means (S404). If a moving image is being shot, video recording is stopped (S405). That is, when a shooting instruction for a video to be displayed is received (shooting instruction receiving unit), a video in a part of the shooting area acquired by the optical zoom lens is shot and recorded (shooting unit). Note that the video that is shot and recorded by the shooting instruction may be a still image or a moving image.

  FIG. 8 is a flowchart showing a flow of overall processing (second embodiment) executed by the system control unit 112 of the imaging apparatus 100 or the CPU of the imaging apparatus 100 (not shown) to represent the embodiment of the present invention. The processing is changed so that video recording is started when a subject is detected within the imaging range of the first imaging means.

  Before performing screen display, it is determined whether or not the camera is currently using zoom (S501). If the zoom is not used in S501, the image of the first imaging means is displayed on the display screen (S505). If the zoom is used in S501, the imaging range of the first imaging means is calculated (S502). The current zoom amounts of the first imaging means and the second imaging means are acquired, and the imaging range of the first imaging means in the video of the second imaging means is obtained by the total comparison of the respective imaging ranges. After obtaining the shooting range of the first image pickup means, it is determined whether or not an object to be detected is detected within the shooting range (S503). If a subject is detected within the shooting range of the first image pickup means, subject capture processing (S504) is performed. If no subject is detected in the shooting range of the first imaging means, the image of the second imaging means and the boundary frame 302 representing the shooting range of the first imaging means calculated earlier are displayed on the screen. (S506). After displaying the image of the second image pickup means, it is determined whether or not an object to be detected is detected within the range of the second image pickup means (S507). When a subject is detected within the shooting range of the second imaging means, a subject frame 304 is displayed around the subject (S508). It is determined whether or not a moving image is currently being recorded (S509). If a moving image is being recorded, the image of the first imaging means is recorded (S510). It is determined whether or not the shutter button has been pressed (S511). If the shutter button has been pressed, processing at the time of pressing the shutter button is performed to perform processing appropriate to the situation (S512).
