It is explanatory drawing which shows the image displayed on a monitor in the case of panning. It is explanatory drawing explaining the method to specify the to-be-photographed object for a panning. It is a flowchart explaining operation | movement of the imaging device by this embodiment. It is a flowchart explaining the operation | movement of step S045 of FIG. 4 in detail.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram showing the configuration of the imaging apparatus 100 according to the first embodiment of the present invention. The imaging apparatus 100 includes an imaging unit 10, a nonvolatile memory 11, a buffer memory 12, an operation detection circuit 13, a monitor control circuit 14, a monitor (display unit) 15, a memory control circuit 16, a memory 17, and a control unit 20. .

  The imaging unit 10 includes an optical system 1, an angular velocity sensor 2, an optical system control circuit 3, an image sensor control circuit 7, an image sensor 8, and a video circuit 9, and captures an optical image (subject image) by the optical system 1. Generate and output an image signal. The optical system 1 includes, for example, a focus lens having a function of adjusting the focus, an anti-shake lens having a function of correcting image shake due to camera shake, an aperture blade, a shutter, and the like.

  The angular velocity sensor 2 detects an angle change (including a movement speed and a movement direction) of the imaging apparatus 100. The angular velocity sensor 2 detects the amount of rotation about the three axes of the imaging apparatus 100. In the case of panning, the orientation of the imaging device 100 is changed by the photographer following the subject of panning. In this case, it is possible to determine whether or not the panning is being performed by detecting the angular change of the imaging apparatus 100 by the angular velocity sensor 2.

  The optical system control circuit 3 controls the focus lens to automatically adjust the focus and automatically adjusts the focus (hereinafter referred to as AF) control function, the shutter control function to control the opening / closing of the shutter, and automatically controls the aperture of the aperture blade. Are provided with an AE control function for adjusting the exposure. The optical system control circuit 3 drives the optical system 1 and adjusts the amount of light to the image sensor 8.

  The imaging element 8 is a CCD (Charge Coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), or the like, and has a light receiving surface on which an optical image output from the optical system 1 is formed, and the formed optical An image is converted into an electrical signal and an analog image signal is output. Further, the image sensor 8 is controlled by the image sensor control circuit 7, and before the shutter is released, the through image signal is continuously output for each frame based on the incident optical image, and the shutter is released. In response, an image signal for a still image is output based on the incident optical image.

  The video circuit 9 amplifies the image signal output from the image sensor 8 and converts it into a digital signal. The image sensor control circuit 7 controls operations such as conversion of an optical image formed on the image sensor 8 into an image signal and output of the converted image signal. For example, the image sensor control circuit 7 performs exposure time control for forming an optical image on the image sensor 8 with an exposure time controlled by the control unit 20, and outputs a plurality of through image signals to the image sensor 8 at intervals of a predetermined time t. Perform through image generation control to be generated. The interval of the fixed time t is, for example, 1/60 seconds.

The nonvolatile memory 11 stores a program for operating the control unit 20 and information such as various settings and shooting conditions input by the user. The non-volatile memory 11 stores information such as the presence / absence of automatic release setting and the setting conditions for automatic release setting based on information input from the operation detection circuit 13, for example.
The buffer memory 12 is a temporary information storage area used for the control process of the control unit 20. For example, a through image signal output from the image sensor 8 or a captured image signal that has been subjected to image processing by the control unit 20 is temporarily stored by the control unit 20.

  The operation detection circuit 13 outputs a control signal corresponding to the operation to the control unit 20 in response to each input unit being operated by the user. Here, the input units are, for example, a power switch 13a, a release switch 13b,. For example, the operation detection circuit 13 outputs a release signal to the control unit 20 in response to the release switch 13b being fully pressed.

  For example, the monitor control circuit 14 performs display control such as turning on and off the monitor 15 and adjusting brightness, and processing for causing the monitor 15 to display the image signal image-processed by the control unit 20. The monitor 15 is a display that displays an image according to an image signal, and is a liquid crystal display such as an LCD (Liquid Crystal Display).

  The memory control circuit 16 controls input / output of information between the control unit 20 and the memory 17. For example, the memory control circuit 16 stores the image signal image-processed by the control unit 20 in the memory 17 or the image stored in the memory 17. A process of reading information such as a signal and outputting the information to the control unit 20 is performed. The memory 17 is a storage medium that can be inserted into and removed from the imaging apparatus 100, such as a memory card, and stores an image signal that has undergone image processing by the control unit 20.

  The control unit 20 is a CPU (Central Processing Unit) that controls the operation of each unit of the imaging apparatus 100 based on a program stored in the nonvolatile memory 11. For example, the control unit 20 turns on the power to the imaging apparatus 100 and controls the driving of the optical system 1 via the optical system control circuit 3 in accordance with a control signal input from the operation detection circuit 13 in response to a user operation. Then, drive control of the image sensor 8 through the image sensor control circuit 7, display control of the monitor 15 through the monitor control circuit 14, and the like are performed.

  The control unit 20 includes an image processing unit 21, a display control unit 22, a shooting control unit 23, a subject detection unit 24, a detection unit 25, a specification unit 26, and a setting unit 27.

  The image processing unit 21 performs image processing on the image signals (still image signal and through image signal) output from the image sensor 8 to the video circuit 9. For example, the image processing unit 21 performs image processing on the through image signal so as to be displayed on the monitor 15 as a moving image, and stores it in the buffer memory 12.

  The detection unit 25 detects panning of the imaging device 100 based on the rotation amounts around the three axes output from the angular velocity sensor 2.

  The subject detection unit 24 detects a main subject from the imaging region of the image based on the image signal output from the imaging unit 10. The subject detection unit 24 detects the main subject when the imaging apparatus 100 is not panned by the photographer, that is, when the detection unit 25 does not detect panning. For example, the subject detection unit 24 detects the subject closest to the imaging device 100 as the main subject when there are a plurality of subjects in the imaging region. The method of detecting the main subject by the subject detection unit 24 may be a method of detecting a person as the main subject, a method of detecting a moving body as the main subject, or a size in the screen. A method of detecting the largest object as a main subject may be used.

  When the detecting unit 25 detects panning, the specifying unit 26 removes the image from the imaging region of the image based on the image signal output from the imaging unit 10 (based on the panning detected by the detecting unit 25). Identify the subject to be shot.

  For example, when the detection unit 25 detects panning, the specifying unit 26 first calculates a motion vector of a subject in the screen for each subject based on the image signal output from the imaging unit 10. Next, the specifying unit 26 specifies a subject whose calculated motion vector is 0 in the screen as a subject to be a panning target. Note that the specifying unit 26 may specify this subject as a subject to be panned when the calculated motion vector is within a predetermined range centered on 0 in the screen.

  In this way, the identification unit 26 can identify the subject to be a panning shot because the photographer pans the imaging device 100 with respect to the subject to be a panning shot, and the photographer This is because the motion vector in the panning target screen becomes 0 when panning can be performed following the above.

  In addition, the detection of the subject in the screen is performed, for example, by dividing the image to be the imaging region into a plurality of blocks and calculating a movement vector for each block, and the same movement vector or the same color or pattern. A block is detected as a block corresponding to the same subject. In this way, the area to be the subject is detected in block units.

  Note that when there are a plurality of subjects whose calculated motion vectors are 0 in the screen, the specifying unit 26 selects, for example, a subject closest to the imaging apparatus 100 among the plurality of subjects as a subject to be panned. As specified. Alternatively, the specifying unit 26 may specify a subject having the largest size among the plurality of subjects as a subject to be shot.

  In the following description, the subject detected by the subject detection unit 24 is referred to as a main subject, and the subject specified by the specification unit 26 is referred to as a subject to be shot. The subject that is the subject of the panning shot is a subject that is detected in the case of panning shot shooting, and the main subject is the subject that is detected in normal shooting.

  The display control unit 22 reads the through image signal that has been image-processed by the image processing unit 21 and stored in the buffer memory 12, and outputs it to the monitor 15 in real time. The display control unit 22 causes the monitor 15 to continuously display through images that are continuously captured based on the image signal from the imaging unit 10 before the release signal is input.

  The display control unit 22 is a subject specified by the specifying unit 26 in response to the fact that the specifying unit 26 specified the subject to be panned together with the image based on the image signal output from the imaging unit 10. The specific subject information, which is information indicating the presence, is displayed on the monitor 15. The specific subject information is, for example, a frame or a cross symbol having a predetermined color and shape (see reference C in FIG. 2 described later. Hereinafter, this frame is referred to as a frame C). For example, the display control unit 22 displays the frame C so that the subject that is the subject of the panning shot is within the frame C. Further, for example, the display control unit 22 may display a cross symbol as the specific subject information so as to be superimposed on the subject to be panned.

  The display control unit 22 causes the monitor 15 to delete the displayed specific subject information when the specific unit 26 no longer detects the subject to be shot after the specific subject information is once displayed. In addition, the display control unit 22 indicates that an imaging condition (described later) is maintained in response to the identification unit 26 identifying a subject that is a panning target (see reference symbol B in FIG. 2, which will be described later). This icon is referred to as icon B).

  The shooting control unit 23 sets shooting conditions for the main subject detected by the subject detection unit 24, and also detects detected subject information (for example, a figure) that is information indicating that the main subject is detected by the subject detection unit 24. 2 is displayed on the monitor 15 (hereinafter referred to as frame A). Details of the detected subject information will be described later. In addition, when the detection unit 25 detects panning, the imaging control unit 23 causes the monitor 15 to delete the displayed detected subject information.

  When the imaging control unit 23 sets the imaging condition and the detection unit 25 detects panning, the imaging control unit 23 displays an icon B indicating that this imaging condition is maintained on the monitor 15. To display.

  The setting unit 27 sets imaging conditions for the subject that is the subject of the panning shot specified by the specifying unit 26. During the period when the release switch 13b is half-pressed, the setting unit 27 sets the subject to be a panning target identified by the identifying unit 26 as long as the identifying unit 26 continues to identify the subject to be panned. On the other hand, the imaging conditions are set repeatedly.

  Next, an operation as an example of the imaging apparatus 100 described above will be described with reference to FIGS. 2 and 3. FIG. 2 is an image displayed on the monitor 15 and is an image of successive frames. Here, as shown in FIG. 2, a case where a photographer performs panning using the imaging apparatus 100 as follows will be described.

  First, the photographer adjusts the orientation of the imaging apparatus 100 so that the house is displayed near the center of the screen of the monitor 15 (see FIG. 2 (1)), and half-presses the release switch 13b. In response to the half-press of the release switch 13b, the subject detection unit 24 detects the house as the main subject in this case.

  Next, the imaging control unit 23 causes the monitor 15 to display detected subject information (for example, frame A), which is information indicating that the subject is the main subject, on the main subject detected by the subject detection unit 24 (FIG. 2 ( (See the reference A in 1).) Here, the detected subject information is displayed as a frame surrounding the subject. More specifically, four corners of a rectangular frame surrounding the subject are displayed as detected subject information.

  Further, the shooting control unit 23 sets shooting conditions for the house that is the main subject detected by the subject detection unit 24. The shooting conditions are set by AF control, AE control, and AWB control for the main subject detected by the subject detection unit 24, for example.

  Here, the AE control is to measure the luminance of the subject and adjust the imaging speed of the imaging device 8 and the aperture of the optical system 1 so as to obtain an appropriate exposure. AWB control is a process of measuring the subject color and adjusting the amplification factor for each color so as to obtain an optimum color. The AF control is control for focusing on a subject.

  Further, this photographing condition is maintained in a period during which the release switch 13b is kept half pressed. For example, the shooting conditions are stored in, for example, the nonvolatile memory 11 of the imaging apparatus 100 during a period in which the release switch 13b is kept half pressed.

  Next, the photographer pans the imaging device 100 in the left direction on the paper surface while pressing the release switch 13b halfway, that is, while fixing the photographing conditions. In this case, the panning of the imaging device 100 in the left direction causes the house to sequentially move in the right direction on the paper surface (see FIGS. 2 (1) to (5)).

  As the imaging device 100 is panned in this way, the detection unit 25 detects panning of the imaging device 100 based on the rotation amounts around the three axes output from the angular velocity sensor 2.

  The imaging control unit 23 causes the monitor 15 to delete the detected subject information in response to the detection unit 25 detecting panning (see FIG. 2 (2)). In addition, the imaging control unit 23 indicates that the imaging condition set when the release switch 13b is half-pressed in response to the detection unit 25 detecting panning (for example, icon B). Is displayed on the monitor 15 (see symbol B in FIGS. 2A to 2). Here, this icon B is displayed on the monitor 15 as “AE AF-L”.

  In FIGS. 2 (1) to (5), the detection unit 25 detects panning. However, since there is no subject whose motion vector is 0 in the screen, the specifying unit 26 is subject to panning. Is not specified (see frames n + 1 to n + 8 in FIG. 3 to be described later).

  Next, the photographer stops panning of the imaging apparatus 100 (see FIGS. 2 (5) to (6)). Next, a car that moves from the left to the right on the page enters the screen of the monitor 15 (see FIG. 2 (6)). The photographer pans the imaging device 100 in the right direction on the paper surface by following the moving vehicle while pressing the release switch 13b halfway (see FIGS. 2 (7) to (11)). In the examples shown in FIGS. 2 (8) to (11), it is assumed that the photographer can follow the panning of the imaging apparatus 100 to the moving car.

  As the imaging device 100 is panned in this way, the detection unit 25 detects panning of the imaging device 100 based on the rotation amounts around the three axes output from the angular velocity sensor 2.

  In response to the detection of the panning by the detection unit 25, the specification unit 26 causes the image to be extracted from the imaging region of the image based on the image signal output from the imaging unit 10 based on the panning detected by the detection unit 25. Identify the subject to be shot. In this case, in FIGS. 2 (8) to (11), the panning of the imaging apparatus 100 is followed by the moving car. Therefore, the specifying unit 26 can specify the subject to be a panning target in FIGS. 2 (8) to (11).

  In FIGS. 2 (8) to (11), the display control unit 22 monitors the icon B indicating that the imaging condition is maintained in response to the identification unit 26 identifying the subject to be shot. 15 (see icon B in FIG. 2 (7) and FIG. 2 (8)).

  In addition, in response to the identification unit 26 specifying the subject to be shot, the display control unit 22 monitors specific subject information, which is information indicating the subject to be shot and specified by the specification unit 26. 15 (see frame C in FIG. 2 (8)). Further, in response to the identification unit 26 identifying the subject to be shot, the setting unit 27 sets an imaging condition for the subject to be shot by the identification unit 26. The setting of the imaging condition is AF control, AE control, and AWB control for a subject to be shot by the specifying unit 26.

  In FIGS. 2 (8) to (11), since the release switch 13b remains half-pressed, the setting unit 27 applies to the subject to be shot by the specifying unit 26, that is, the subject that is a moving car. Then, AF control, AE control, and AWB control are continuously performed.

  Thereafter, when the photographer fully presses the release switch 13b at the timing of FIG. 2 (11), for example, the imaging apparatus 100 captures an image as shown in FIG. 2 (12). Note that by setting the shutter speed to be suitable for panning and shooting, the car can be shot and an image as shown in FIG. 2 (12) can be shot.

  Next, with reference to FIG. 3, the relationship between the movement vector of the subject 1, the movement vector of the subject 2, and the panning vector (camera pan speed) detected by the detection unit 25, and the panning target by the specification unit 26. A method for specifying the subject will be described.

Here, the house that is the main subject described in FIG. 2 is set as the subject 1, and the car that is the subject that is the subject of the panning described in FIG. In addition, the time in the number of frames as a unit is taken as the horizontal axis, and the area corresponding to each subject in the screen, that is, the position of each subject in the screen is taken as the vertical axis. Here, as the position of each subject, the position of each subject in the horizontal direction within the screen (for example, the horizontal direction in the screen shown in FIG. 2) is shown. In addition, the center of each subject in the screen is shown connected by a straight line in the order of frames.
The amount of change in the position of each subject at the screen position between consecutive frames corresponds to the movement vector of each subject. In addition, although the position of each subject in the screen position is a position on a two-dimensional plane, in FIG. 3, it is schematically illustrated as a position in one dimension (for example, the horizontal direction described above).
In FIG. 3, the symbol “◯” indicates that a frame (frame A or frame C) is displayed for the subject. In addition, a symbol (●) indicates that a frame (frame A or frame C) is displayed for the subject and that the shooting condition is set for the subject by AF control, AE control, and AWB control. Show.

  3 corresponds to the panning shot described with reference to FIG. 2. For example, frame n + 1 in FIG. 3 corresponds to FIG. 2 (1), and frame n + 2 in FIG. 3 corresponds to FIG. 2 (2). The frames n + 3 to n + 5 in FIG. 3 correspond to FIGS. 2 (3) to (5). 3 corresponds to FIG. 2 (6), frames n + 7 to n + 8 in FIG. 3 correspond to FIG. 2 (7), and frame n + 9 in FIG. 3 corresponds to FIG. 2 (8). Further, frames n + 10 to n + 14 in FIG. 3 correspond to FIGS. 2 (9) to (10), frame n + 15 in FIG. 3 corresponds to FIG. 2 (11), and frame n + 17 in FIG. 3 corresponds to FIG. Correspond.

  In FIG. 3, for example, in frames n + 8 to n + 14, since the value of the panning vector (camera pan speed) detected by the detection unit 25 is not 0, it is detected that the imaging device 100 is panned. 25 can be determined. In this case, the subject 1 and the subject 2 are detected in the screen, but the subject 1 is moving in the screen. On the other hand, the subject 2 is stopped in the screen because it is followed by the photographer. Therefore, the specifying unit 26 can specify the subject that is the subject of the panning for the subject 2 that is the subject whose motion vector is 0 in the screen.

  Next, an example of the operation of the imaging apparatus 100 will be described with reference to FIGS. 4 and 5. Here, an operation of the imaging apparatus 100 after the user presses the power switch 13a and the power is turned on will be described.

  First, in response to the power supply of the imaging apparatus 100 being turned on, in step S001, the control unit 20 resets the circuit system and initializes the system. In the next step S003, the control unit 20 activates the image sensor 8 to make it possible to continuously capture through images. In the next step S 004, the control unit 20 turns on the monitor 15 and causes the monitor 15 to display a through image from the image sensor 8.

  In the next step S021, the control unit 20 performs AE control. In the next step S022, the control unit 20 performs AWB control. In the next step S023, the control unit 20 performs AF control.

  In the next step S024, the control unit 20 determines whether or not the release switch 13b is half-pressed. If the release switch 13b is not half-pressed in step S024, the control unit 20 repeats the processing from step S021. On the other hand, when the release switch 13b is half-pressed in step S024, the control unit 20 advances the process to step S040.

  Next, in step S040, the subject detection unit 24 of the control unit 20 detects the main subject from the imaging region of the image based on the image signal output from the imaging unit 10. Next, in step S041, the imaging control unit 23 of the control unit 20 monitors detected subject information (for example, frame A in FIG. 2A) that is information indicating that the subject is the main subject detected by the subject detection unit 24. 15 is displayed. By the processing in step S041, a frame A shown in FIG. 2 (1) is displayed.

  Next, in steps S042 to S044, the shooting control unit 23 of the control unit 20 sets shooting conditions for the main subject detected by the subject detection unit 24. Specifically, the imaging control unit 23 of the control unit 20 performs AE control, AWB control, and AF control on the main subject detected by the subject detection unit 24, respectively. In the AE control here, the imaging control unit 23 of the control unit 20 executes AE control similar to the AE control in step S021 described above, and also sets the aperture and shutter speed during imaging. These photographing conditions are stored in the nonvolatile memory 11 of the imaging device 100.

  In the next step S045, the control unit 20 performs a panning process. The panning process in step S045 will be described later with reference to FIG.

  In the next step S051, the control unit 20 determines whether or not the release switch 13b that has been half-pressed is further pressed and a release signal is input from the release switch 13b. If no release signal is input in step S051, the control unit 20 advances the process to step S052.

  Next, in step S052, the control unit 20 determines whether or not the release switch 13b is half-pressed. If the release switch 13b is half pressed in step S052, the control unit 20 repeats the processing from step S045. On the other hand, if the release switch 13b is not half-pressed in step S052, the control unit 20 repeats the processing from step S021.

  On the other hand, if a release signal is input in step S051, the control unit 20 executes one-frame shooting processing in step S061, records the image shot in step S062, and then performs the processing from step S021. repeat.

  Next, the panning process in step S045 of FIG. 4 will be described with reference to FIG. First, in step S <b> 301, the detection unit 25 of the control unit 20 determines whether there is panning of the imaging apparatus 100 based on the rotation amounts around the three axes output from the angular velocity sensor 2. If it is determined in step S301 that there is no panning, the control unit 20 advances the process to step S302. If it is determined in step S301 that there is panning, the control unit 20 performs the process in step S311. Proceed to

  If it is determined in step S301 that panning is present, in step S311, the control unit 20 determines whether it is a panning shot. The determination of whether or not this is a panning shot is made based on whether or not the specifying unit 26 of the control unit 20 has specified a subject to be shot. Specifically, when the specifying unit 26 of the control unit 20 specifies the subject to be shot, the control unit 20 determines that it is a panning, and the specifying unit 26 of the control unit 20 If the subject to be shot is not specified, the control unit 20 determines that the shot is not panning. If it is determined in step S311 that it is a panning shot, the control unit 20 advances the process to step S320. If it is determined in step S311 that it is not a panning shot, the control unit 20 performs the processing step. The process proceeds to S312.

  If it is determined in step S311 that it is not a panning shot, in the next step S312, the imaging control unit 23 of the control unit 20 monitors the displayed frame (for example, the frame A in FIG. 2 (1)) on the monitor 15. To erase. In the next step S313, the imaging control unit 23 of the control unit 20 displays an icon (for example, the icon B in FIG. 2B) on the monitor 15. Then, the control part 20 returns a process to step S051 of FIG. 4 mentioned above.

  The processing from step S312 to step S313 described above corresponds to the processing in FIG.

  On the other hand, if it is determined in step S301 that there is no panning, in the next step S302, the control unit 20 sets the AE, AF, and AWB when half-pressed, that is, the shooting condition when half-pressed, to the nonvolatile memory 11. Read from and return. The AE, AF, and AWB when half-pressed are control values obtained by the AE control, AF control, and AWB control in steps S042 to S044 described above.

  In step S303, the control unit 20 determines whether panning has occurred after the release switch 13b is half-pressed. If it is determined in step S303 that panning has occurred, in step S304, the control unit 20 displays an icon (for example, the icon B in FIGS. 2 (2) to (7)), and the process has been described above. The process returns to step S051 in FIG. On the other hand, when it is determined in step S303 that panning has not been performed, the control unit 20 returns the process to step S051 of FIG. 4 described above.

  The processing from step S302 to step S304 described above corresponds to the processing from (2) to (7) in FIG.

  On the other hand, if it is determined in step S311 described above that the shot is a panning shot, in step S321, the display control unit 22 of the control unit 20 indicates that the subject is the subject of the panning shot specified by the specifying unit 26. The specific subject information (for example, the frame C in FIG. 2 (8)), which is information, is displayed on the monitor 15. Next, in step S322, the display control unit 22 of the control unit 20 causes the monitor 15 to delete the displayed icon (for example, the icon B in FIG. 2 (7)).

  In the next steps S323 to S325, the setting unit 27 of the control unit 20 sets the imaging conditions for the subject to be shot by the specifying unit 26 specified in step S320 described above. That is, the setting unit 27 of the control unit 20 performs AE control, AWB control, and AF control on the subject to be shot by the specifying unit 26. Then, the control part 20 returns a process to step S051 of FIG. 4 mentioned above.

  The processing from step S321 to step S325 described above corresponds to the processing from (8) to (11) in FIG.

  According to the above-described imaging device 100 according to the present embodiment, when the display control unit 22 detects panning, the flow specified by the specifying unit 26 together with the image based on the image signal output from the imaging unit 10. Specific subject information which is information indicating that the subject is a subject to be photographed is displayed on the monitor 15. Thus, when the photographer performs panning, the photographer can confirm which subject (or object or image region) is the subject to be panned.

  Further, for example, during panning shooting, since the subject to be panned can be confirmed on the screen of the monitor 15, the photographer confirms whether or not the subject to be panned is in focus. You can check the shooting conditions. In addition, since the photographer can confirm the subject to be a panning shot on the screen of the monitor 15, it is easy to pan the imaging apparatus 100 so as to follow the subject to be a panning shot. Also, in the case of panning, whether or not the subject to be panned can be followed by checking whether or not specific subject information for the subject to be panned is displayed. Can be confirmed.

  In addition, the setting unit 27 maintains the imaging conditions set when the release switch 13b is half-pressed on the subject to be shot by the specifying unit 26 during the period when the release switch 13b is half-pressed. To do. As a result, in the case of panning, the imaging device 100 can shoot a subject to be panned under suitable shooting conditions regardless of the timing when the photographer fully presses the release switch 13b. it can.

  The detected subject information and the specific subject information described above have been described as being displayed as frames, as indicated by a frame A and a frame C in FIG. 2, but the detected subject information and the specific subject information are mutually connected. A frame that can be distinguished may be used. For example, the frame colors of the detected subject information and the specific subject information may be different from each other. Further, the first frame of the detected subject information and the specific subject information may be white black and the second frame black. Further, the first frame may be a solid line and the second frame may be a wavy line. Further, the first frame may be a single frame and the second frame may be a double frame.

  Moreover, the 1st frame may blink, and the 2nd frame may always be lighted (always light). Both frames are blinking, but their periods may be different. Further, the shapes of the detected subject information and the specific subject information may be different so that one of them is a frame and the other is a cross.

  Thus, by allowing the detected subject information and the specific subject information to be visually distinguished in the screen of the monitor 15, the photographer can easily determine whether the subject is a subject to be panned or a main subject. Can be confirmed. In the above description, an icon is displayed as indicated by reference numeral B in FIG. 2, but the shape or character information of this icon is arbitrary.

  Although the detected subject information, the specific subject information, and the icon are described as being displayed on the screen of the monitor 15, the monitor 15 or the imaging device 100 has the detected subject information, the specific subject information, and the icon. You may display and display on the display part different from the monitor 15. FIG. The display unit different from the monitor 15 is a display unit for setting shooting conditions and shooting modes, for example. Moreover, you may show by lighting or light extinction of LED which the imaging device 100 has. Moreover, you may show with a sound and an audio | voice via the speaker which the imaging device 100 has. Even in this case, in the case of panning, the photographer can detect whether or not the imaging apparatus 100 can detect the subject to be panned (whether or not the subject to be panned can be tracked), or Whether or not the main subject is detected can be confirmed.

  In the screen of the monitor 15, as shown in FIG. 2, it is preferable to display the detected subject information or the specific subject information so as to overlap the subject display. In this way, as shown in FIG. 2, the photographer can easily confirm the subject visually, and can easily follow the subject that is the subject of panning.

  In the above description, the case where there is one main subject and one subject to be panned has been described, but there may be a plurality of main subjects and subject to be panned. In this case, the control unit 20 may display the detected subject information for each of the plurality of main subjects, and may display the specific subject information for each of the plurality of subjects to be shot.

In the above description, the shooting control unit 23 sets shooting conditions for a main subject, and the setting unit 27 sets shooting conditions for a subject to be panned. Since the photographing control unit 23 and the setting unit 27 have the same function, the photographing control unit 23 and the setting unit 27 may be configured integrally.
When integrated, for example, when the integrated shooting control unit 23 (or setting unit 27) sets shooting conditions for the main subject, the specifying unit 26 specifies the subject to be panned. In this case, the control unit 20 first changes the main subject to a subject to be subjected to panning. Next, the integrated shooting control unit 23 (or setting unit 27) sets shooting conditions for the subject to be panned, that is, the changed main subject.
Specifically, in a step between steps S311 and S320 in FIG. 5, the control unit 20 changes the main subject detected by the specifying unit 26 to a subject to be subjected to panning. Further, the control unit 20 performs the subsequent processing (see steps S321 to S325 in FIG. 5) on the subject to be panned, that is, the changed main subject.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes design and the like within a scope not departing from the gist of the present invention.
