Description

  The present invention relates to an imaging apparatus, a control method thereof, and a program technique.

  In recent years, the zoom performance of the camera has been improved, and it has become possible to capture more distant objects more clearly. However, since the angle of view is narrowed when shooting in telephoto, it is necessary to devise a mechanism for not losing sight of the subject in shooting when shooting in telephoto.

  Patent Document 1 has a plurality of imaging systems, one is an imaging optical system that actually performs imaging, and the other is a wide-range display imaging system for confirmation. A technique related to a target recognition system is disclosed.

  Patent Document 2 discloses a technique related to an assist image that cuts out an image obtained by the digital zoom when the digital zoom is performed, displays a zoom image of the zoom range inside, and displays an ambient image around it.

  However, in the technique of Patent Document 1 or Patent Document 2, the surrounding situation can be confirmed on a monitor. However, if it is necessary to suddenly change the angle of view and the composition of the subject, it is necessary to perform a zoom operation. In the case where the subject is, for example, a bird and is moving, it is not possible to easily record an image in which the angle of view and the composition of the subject are stable.

FIG. 2 will be described.

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

The display screen (1) shows a state in which a live view video (through image) before the digital zoom-up operation is displayed. Here, the image displayed on the full screen is an image not subjected to digital zoom processing.
The display control shown in (1) is performed in the process at step S104 in FIG.

  The display screen of (2) shows a state where the live view image after the digital zoom up operation (digital zoom up processing) is performed is displayed. Here, the angle of view 303 of the same size as that before the digital zoom up operation is displayed on the entire screen, and the boundary frame 302 is displayed as a boundary with the angle of view 301 after the digital zoom up operation.

That is, in this state, the angle of view 303 that is the entire image acquired by the lens is displayed on one screen, and the boundary line between the displayed angle of view 303 and the range recorded after the actual digital zoom-up operation is performed. The boundary frame 302, which is In this way, the image of the angle of view 303 before the digital zoom-up operation is displayed outside the boundary frame 302, and the image of the angle of view 301 after the digital zoom-up operation is displayed inside the boundary frame 302. Even after the digital zoom-up operation, the angle of view 303 before the digital zoom-up operation, which is an image around the digital zoom-up operation, can be simultaneously confirmed in the live view image.
Note that the display control shown in (2) is performed by the processing in step S105 in FIG.

On the display screen of (3), after a while for a while from the state of the display screen of (2), the subject (car) moves to the image in the angle of view 303, and a new detection of the subject is It is shown. Note that a subject frame 304 is displayed for a newly detected subject.
Note that the display control shown in (3) is performed by the processing in step S107 in FIG.

  On the display screen of (4), the subject (automobile) moves from the video in the angle of view 303 to the video in the angle of view 301 after the digital zoom-up operation after a further time has elapsed from the state of the display screen of (3). This shows that the subject is recognized to be inside the bounding frame 302.

  That is, in this case, it is determined whether the subject has moved within the angle of view 301 after the digital zoom up operation from the entire angle of view 303 acquired by the imaging apparatus, and the subject is moved within the angle of view 301. The display size of the angle of view 301 is automatically switched to full-screen display.

  As described above, when it is determined that the subject has moved, the angle of view 301 after the digital zoom-up operation including the subject moved to the boundary frame 302 is controlled to be displayed on one screen on the entire screen.

Further, at this time, since the digital zoom up operation has already been performed, the subject moved within the angle of view 301 can be photographed without suddenly performing the digital zoom up operation, so that the composition of the angle of view and the subject is stable. Images can be recorded.


Note that the display control shown in (4) is performed by the processing in step S114 of FIG.
FIG. 3 will be described.

FIG. 3 is a flowchart showing the overall flow of 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 an 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 determines whether or not the user is using the digital zoom operation in a state where the live view image (through image) before the digital zoom operation is displayed on the display screen of (1). Do. If it is determined that the user is in use (Yes), the process proceeds to step S102, and if it is determined that the user is not used (No), the process proceeds to step S104.

  In step S102, the imaging apparatus 100 acquires an operation amount (for example, double zoom) before and after the digital zoom operation to the tele side, and displays an angle of view 303 having the same size as that before the digital zoom operation in one screen. Thus, the display range of the boundary frame 302 representing the narrow angle of view 301 after the digital zoom operation is calculated in the angle of view 303.

  That is, here, with one zoom operation for digital zoom, a first angle of view 303 which is the same size as the angle of view before the zoom operation, and a second angle of view 301 which is a size based on the operation amount by the zoom operation. , Is set (setting means).

  Alternatively, the operation amount (for example, 0.5 × zoom) before and after the digital zoom operation to the wide side is acquired, and a wide angle of view 403 after the digital zoom operation is displayed in one screen. The display range of the bounding frame 302 representing the angle of view 401 of the same size as that before the digital zoom operation is calculated.

That is, here, by one zoom operation with respect to the digital zoom, a first angle of view 401 having the same size as the angle of view before the zoom operation, and a second angle of view 403 having a size based on the operation amount by the zoom operation. Are set (setting means).
The flow of the detailed process performed in step S102 will be described with reference to FIGS. 4 and 5.

  In step S <b> 103, the imaging apparatus 100 determines whether an object to be a subject is detected inside the boundary frame 302 after the digital zoom operation. If it is determined that the inside is detected (Yes), the process proceeds to step S114, and if it is determined that nothing to be the subject is detected inside (No), the process proceeds to step S105.

In other words, when it is determined that the subject is detected inside the boundary frame 302 after the digital zoom operation (Yes), the image in which the angle of view and the composition of the subject are stable is recorded as described above. It can be said that the subject (automobile) has moved within the range of the angle 301 or the angle of view 401.

  That is, it is determined whether or not the subject has moved from the image outside the boundary adjusted by the area adjustment unit in step S105 to the image inside the boundary (movement determination unit).

  At this time, in step S104, since the user is not using digital zoom at this time, the imaging apparatus 100 displays the full angle of view of the same size as before the digital zoom operation on the display screen.

  In step S105, the imaging apparatus 100 displays the two angle of view after the digital zoom operation, and, among the angle of view after the digital zoom operation, the angle of view actually recorded after the digital zoom operation calculated in step S102. Is displayed.

  In other words, if the user operates the digital zoom to the tele side with the boundary frame 302, the user can also grasp the wide view angle 303 before shooting, and the digital zoom to the wide side. Even when the operation of is performed, the angle of view 401 in which the imaging range before the operation is narrow can be grasped.

  That is, here, as shown in FIG. 4 or FIG. 5, the image within the first angle of view and the image within the second angle of view acquired using digital zoom are displayed on one screen (display control means) Further, by performing a single zoom operation on the digital zoom, the area in which the image within one of the two angles of view set in step S102 is displayed in one screen to be displayed is reduced, and The respective display areas are adjusted so as to enlarge the area in which the image within the other angle of view of the two angles of view set in step S102 is displayed (region adjustment means).

  In step S114, when it is determined that the subject has moved in step S103, the imaging apparatus 100 performs control so that the image within the angle of view including the moved subject is displayed on one display screen 300 (full screen) Screen display control means).

  In step S <b> 106, the imaging apparatus 100 determines whether an object that is a subject outside the boundary frame 302 after the digital zoom operation is detected. If it is determined that the object is detected (Yes) outside the boundary frame 302, the process proceeds to step S107, and if it is determined that nothing to be an object is detected outside the boundary frame 302 (No). The process proceeds to step S108.

In other words, when it is determined that the subject is detected outside the boundary frame 302 (Yes), as described above, the angle of view 303 or the angle of view 403 after the digital zoom operation, which is the surrounding situation, is determined. This is a state in which the subject (automobile) has moved from the outside of the angle of view 303 or the angle of view 403 in the video.
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 a moving image is currently being recorded (photographed). If it is determined that the moving image is already recorded (Yes), the process proceeds to step S109. If it is determined that the moving image is not currently recorded (No), the process proceeds to step S110.

  In step S109, the imaging apparatus 100 continues recording at the angle of view 301 or angle of view 401 within the boundary frame (recording range frame) 302, which is the moving image size that the user wants to record after digital zoom operation.

  That is, here, when an instruction to capture an image is given in a state where two angles of view are set in step S102, the image is captured at one or both of the two angles of view in step S102. An image can be recorded (recording means).

  Here, when the recording range frame is designated in the boundary frame (recording range frame) 302, the recording is continued at one of the angle of view 301 or the angle of view 401 in the boundary frame (recording range frame) 302. When an instruction to shoot an image is given in a state in which two angles of view are set in step S102, imaging is performed at a narrower angle of view among the two angles of view set by the recording unit, and the angle of view and the subject Images with a stable composition can be recorded.

  When the recording range frame is designated by the size of the display screen 300, the recording may be continued at one of the angle of view 303 or the angle of view 403 within the size of the display screen 300. When an instruction to shoot an image is issued in a state in which two angles of view are set in step S102, the image is captured at a wider angle of view among the two angles of view set by the recording unit, and the angle of view and the subject Images with a stable composition can be recorded.

  Furthermore, in the case where the recording range frame is designated in both the boundary frame (recording range frame) 302 and the size of the display screen 300, the angle of view 303 within the size of the display screen 300 and the angle of view 301 of the recording range frame Both records may be continued.

  Furthermore, in the case where the recording range frame is designated in both of the boundary frame (recording range frame) 302 and the size of the display screen 300, the angle of view 403 within the size of the display screen 300 and the angle of view 401 of the recording range frame Both records may be continued. If an instruction to capture an image is given in a state where two angles of view are set in step S102, images are shot at both the narrower and wider angles of view among the two angles of view set by the recording means. An image with a stable angle of view and composition of the subject can be recorded.

  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 is pressed (Yes), the process proceeds to step S111, and if it is determined that the recording shutter button is not pressed (No), the process proceeds to step S112.

  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.

  In step S112, the imaging apparatus 100 determines whether the reset button for displaying the border frame (recording range frame) has been pressed. If it is determined that the border frame display reset button is pressed (Yes), the process proceeds to step S113. If it is determined that the border frame display reset button is not pressed (No), the process returns to step S101.

In step S113, the imaging device 100 erases the display of the boundary frame (recording range frame) from the display screen 300, and the image in the boundary frame (recording range frame) which is the size the user wants to record in step S102. The setting of the angle 301 or the angle of view 401 is also reset at the same time.
FIG. 4 will be described.

  FIG. 4 shows the transition of the screen displayed when performing the digital zoom operation on the tele side which is 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 ) And a flowchart (right diagram) showing the flow of processing at that time.

  When determining that the digital zoom operation has been performed on the tele side (S201), the imaging apparatus 100 recalculates the size of the boundary frame 302 in order to update the size of the boundary frame 302 after the digital zoom operation (S203). The calculation method at this time is the same as the calculation method described in S102 in FIG. After the size of the new boundary frame 302 after the digital zoom operation is calculated, the boundary frame 302 on the screen is reduced to a new range (S204). Every time it is determined that the digital zoom operation has been performed on the tele side (S202: Yes), the boundary frame 302 is recalculated and the displayed boundary frame 302 is updated.

  The example of the display screen of (5) represents the screen display when the zoom-up operation is performed on the tele side. In the video displayed on the display screen 300, the angle of view 303 remains the same, and the boundary frame 302 is reduced after the zoom-up operation. That is, when the digital zoom operation is performed to the tele side, only the boundary frame 302 after the zoom-up operation is changed and displayed in one screen displayed by the display control means.

That is, in this case, the area adjustment means is configured to display an image within the set second angle of view 301 in one screen displayed by the display control means by one zoom operation to the tele side. The area in which the image within the set first angle of view 303 is displayed is enlarged.
Further, the area adjusting means adjusts the respective display areas so that the video in the first angle of view 303 displays the periphery of the video in the second angle of view 301.
Then, a boundary frame 302 is displayed which allows the boundary between the image in the second angle of view 303 adjusted by the region adjusting means and the image in the first angle of view 303 to be identified (boundary display means).
FIG. 5 will be described.

  FIG. 5 shows the transition of the screen displayed when performing the digital zoom operation on the wide side 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 ) And a flowchart (right diagram) showing the flow of processing at that time.

  When it is determined that the digital zoom operation has been performed on the wide side (S301), the imaging device 100 recalculates the size of the boundary frame 302 in order to update the size of the boundary frame 302 after the digital zoom operation (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 boundary frame 302 on the screen is reduced to a new range (S304). After updating the boundary frame 302, the size of the angle of view 403 displayed on the screen is enlarged (S305). Each time it is determined that a zoom operation has been performed (S302: Yes), the boundary frame 302 is recalculated and the displayed boundary frame 302 is updated. When zooming to the wide side, the size of the angle of view 403 displayed on the screen and the size of the border frame 302 change simultaneously.

  The example of the display screen of (6) represents the screen display when the zoom down operation is performed on the wide side. In the image displayed on the display screen 300, the size of the angle of view 403 is enlarged and the boundary frame 302 is reduced after the zoom-down operation. That is, when the digital zoom operation is performed to the wide side, the angle of view 403 (enlarged) after the zoom-down operation and the boundary frame 302 are both changed and displayed in one screen displayed by the display control unit. ing.

That is, here, by one zoom operation to the wide side, the area adjusting means is an area in which the video within the set first angle of view 401 is displayed in one screen displayed by the display control means. The area in which the image within the set second angle of view 403 is displayed is enlarged.
Further, the area adjusting means adjusts the respective display areas so that the video in the second angle of view 403 displays the periphery of the video in the first angle of view 401.
Then, a boundary frame 302 is displayed that allows the boundary between the image in the first angle of view 401 and the image in the second angle of view 403 adjusted by the region adjustment unit to be identified (boundary display unit).

  FIG. 6 shows an operation example for changing the subject frame 304.
