[Example 1]
Hereinafter, the frame speed control method according to the first embodiment of the present invention will be described with reference to FIGS. 2, 3, 4, 5, 6, and 7.

  FIG. 3 is a flowchart showing frame speed control photographing according to the first embodiment of the present invention. FIG. 4 shows details of the phase selection method. FIG. 5 shows details of the rotation detection and rotation speed detection method. FIG. 6 shows details of the continuous shooting sequence control. FIG. 7 shows details of the phase adjustment.

  First, a flow chart of frame speed control shooting will be described with reference to FIG.

  The imaging apparatus main body 1 is activated by the power ON operation in step S100.

  In step S101, when it is detected that the control unit 20 is set to a mode for photographing a rotating subject (hereinafter referred to as a rotation mode), a phase selection screen is displayed on the display unit 5 in step S102. Specifically, the setting of the rotating body photographing mode may be selected by the mode dial 3 of the imaging apparatus or may be selected from the MENU screen of the imaging apparatus.

  In step S102, the user selects a plurality of face orientations (phases) of a desired subject, and in step S103, the control unit 20 stores the selected phase information.

  Details of phase selection will be described later.

  When the control unit 20 detects SW1 of the release button 2 in step S104, AF (autofocus) and AE (photometry) are started in step S105. By this operation, the driving of the focus lens (not shown) and the shutter time and aperture value of the imaging apparatus are determined. Thereafter, in step S106, the control unit 20 uses the subject recognition and face recognition information acquired by the AE unit 26 to cause the rotation detection unit 27 to determine whether the subject is performing a rotational motion.

  In the present embodiment, the AE sensor included in the AE unit 26 is a solid-state imaging device such as a CCD or CMOS sensor as described above, and can detect a subject based not only on the brightness of the subject but also on the face and color recognition. . After recognizing the face of the main subject, the rotation detection unit 27 turns off the face recognition because the subject is rotating, and recognizes the rotation of the main subject when the face is recognized again.

  If the subject is rotating in step S106, the control unit 20 causes the rotation detection unit 27 to detect the rotation speed in step S107.

  Details of rotation speed detection will be described later.

  Next, when the control unit 20 detects SW2 of the release button 2 in step S108, the control unit 20 stands by until the sequence control start reference is detected in step S109.

  In step S109, after the sequence control start reference is detected, in step S110, the control unit 20 performs continuous shooting sequence control based on the rotation speed information and the face recognition information, and the orientation of the face of the subject stored in step S103 ( The imaging unit 21 is caused to perform an imaging operation at the timing of (phase) (S111).

  Details of the continuous shooting sequence control will be described later.

  The control unit 20 that has detected that SW2 of the release button 2 has been released in step S112 displays the captured image on the display unit 5 in step S113.

  In step S114, the control unit 20 performs a display for confirming whether the display image is captured in the direction of the face imaged by the user, together with the image displayed in step S113, and operates or displays the operation unit 6. The user is allowed to select using the touch operation function of the unit 5. If it is selected in step S114 that the display image is different from the orientation of the face imaged by the user, the process proceeds to step S115, and the control unit 20 displays the phase adjustment screen on the display unit 5.

  Details of the phase adjustment will be described later.

  Next, with reference to FIG. 4, the phase selection method in step S102 will be described in detail. 4A is a phase selection screen, and FIG. 4B is a diagram showing the face orientation of the phase selected in FIG. 4A. In FIG. 4A, 200 is an operation instruction display for the user, 201 is a user's line of sight with respect to the subject, 202 is a subject display when the subject is viewed from above, 203 is a selection display in which the orientation of the subject is divided every 45 degrees, 204 Indicates a selection display selected by the user in the selection display 203. In FIG. 4B, 205a, 205b, and 205c indicate the orientation of the face of the subject when 204a, 204b, and 204c in FIG. 4A are selected (hereinafter referred to as face 205a, face 205b, face, respectively). Direction 205c). In this embodiment, face recognition is used as means for determining the orientation of the subject, but any direction detection means may be used.

  In FIG. 4, the user selects a desired face orientation in the selection display 203 using the operation of the operation unit 6 or the touch operation function of the display unit 5 in accordance with the instruction of the operation instruction display 200. In the present embodiment, the operation display 203 is divided every 45 degrees, but may be any number of divisions such as every 15 degrees or every 30 degrees.

  In the present embodiment, it is assumed that the selection display 204a, the selection display 204b, and the selection display 204c are selected. The selection display 204a, selection display 204b, and selection display 204c selected by the user are displayed separately from the selection display 203. In the present embodiment, the selection display 203 indicating the selectable phase before being selected by the user is displayed in white, and the selection display 204 selected by the user is displayed in black.

  The phase selection method allows the user to select a desired subject orientation.

  Next, with reference to FIG. 4 and FIG. 5, the detailed description regarding the rotational speed detection method of step S107 is given.

  FIG. 5 is a diagram illustrating a state where the subject rotates along the time axis.

  In FIG. 5, reference numeral 300 denotes a subject state in which face detection is possible, and 301 denotes a subject state in which face detection is impossible. The subject state 300 is a state in which the face of the rotating subject starts to be seen, and the subject state 301 is a state immediately before the subject's face is completely hidden. If the time from the subject state 300 to the subject state 301 is T and the rotational speed (angular speed) is V, the rotational speed V of the subject is V = 180 / T.

  Thus, the rotation detection unit 27 detects the rotation speed. The control unit 20 calculates the time from the sequence control reference to the face orientation 205a, the face orientation 205b, and the face orientation 205c using the rotation speed information. That is, if the time during which the subject rotates by 1 ° is t, then t = 1 / V = T / 180. Therefore, with the subject state 301 as a reference, the time until the subject's face orientations 205a, 205b, and 205c in FIG. 4 is 135t, 270t, and 315t, respectively. In the present embodiment, the sequence control reference will be described as the subject state 301 in FIG.

  With the above rotation speed detection method, the control unit 20 can calculate the time until the face of the subject selected by the user.

  Next, the continuous shooting sequence control in steps S109 and S110 will be described in detail with reference to FIG.

  FIG. 6A is a diagram showing an imaging sequence per frame when an imaging apparatus having a continuous shooting function of 5 frames per second is taken as an example. FIG. 6B is a diagram showing continuous shooting sequence control in a case where a spin of a figure skating player who makes 2.5 rotations per second is shot by an imaging device having a continuous shooting performance of 5 frames per second.

  In FIG. 6A, after detecting the sequence adjustment reference, the control unit 20 retracts the main mirror 22a and the sub mirror 22b outside the luminous flux 24 in the section A, and causes the imaging unit 21 to perform an imaging operation at timing Pa. To do. Thereafter, the control unit 20 returns the main mirror 22a and the sub mirror 22b to the initial positions in the section B, and causes the AF means 25 and the AE means 26 to perform distance measurement and image recognition in the section C. In the section D, the main mirror 22 a and the sub mirror 22 b are retracted out of the luminous flux 24 again to perform the next imaging. In the present embodiment, if the section B to the section D are one frame, it is an imaging device of 5 frames per second, so it is 200 ms per frame, and the sections B, C, and D are 60 ms, 80 ms, and 60 ms, respectively. To do.

  In FIG. 6B, the control unit 20 starts sequence control in step S110, and causes the imaging unit 21 to perform an imaging operation at the timing Pa at timing P1. Thereby, the face orientation 205a can be imaged. Next, based on the time information calculated from the rotation speed information of the subject, it can be predicted that the imaging timing of the face direction 205b will come after 120 ms, so the control unit 20 reduces the time of the section C by 80 ms, Frame speed control is performed so that timing P is matched with timing P2. In the present embodiment, it is assumed that the subject is rotating at a certain point, and therefore there is no problem even if the time of the section C is shortened.

  Subsequently, since it can be predicted that the imaging timing of the face orientation 205c will come after 360 ms, the control unit 20 adds 160 ms to the section C and performs frame speed control so that the timing P matches the timing P3. Here, although the imaging timing P3-1 of the face orientation 205c comes immediately after the timing P2, the imaging is delayed until the timing P3. This is because the interval between the timing P2 and the timing P3-1 is short, and the timing cannot be adjusted only by shortening the section C.

  As described above, when the time between the plurality of selected phases is short enough to be adjusted by the adjustment of the section C, the control unit 20 performs the frame speed control so as to match the timing up to the next same phase. Further, as a method of imaging the timing P3-1 immediately after the timing P2, the main mirror 22a and the sub mirror 22b in the section B are not moved to the initial positions after the imaging at the timing P1, and the imaging light flux 24 is used. You may always be in the retracted state. As a result, when the timing P2 and the timing P3-1 are imaged, it is not necessary to take the time of the section B and the section D. Therefore, the timing P3-1 can be imaged immediately after the timing P2. .

  By performing the control described above, it is possible to perform continuous shooting that matches the face orientation 205a, the face orientation 205b, and the face orientation 205c.

  Next, with reference to FIG. 7, a detailed description will be given regarding the phase adjustment.

  FIG. 7 shows a phase adjustment screen. In FIG. 7, reference numeral 500 denotes an operation instruction display for the user, and 501 denotes an arrow indicating a movable direction during phase adjustment.

  In FIG. 4, the user selects the selection display 204 to be phase-adjusted among the selection displays 204 using the operation of the operation unit 6 or the touch operation function of the display unit 5 in accordance with the instruction of the operation instruction display 500. In the present embodiment, the selection display 204c will be described as being selected. The selection display 204c selected by the user can be moved in either direction of the arrow 501 using the operation of the operation unit 6 or the touch operation function of the display unit 5. At this time, the selection display 204c moves by a user operation at a predetermined interval.

  By performing the phase adjustment described above, the user can finely adjust the face direction and proceed to the next shooting when the captured face direction is different from the desired direction.

  By the series of continuous shooting sequence control described above, the user can easily take images of the rotating subject in various directions.

[Example 2]
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.

  FIG. 8 is a flowchart showing the operation of the main part performed by the control unit 20. FIG. 9 is a diagram showing an example of setting the photographing conditions in the second embodiment of the present invention. FIG. 10 is a view showing a display example in the viewfinder in the second embodiment of the present invention. FIG. 11 is a diagram for defining the rotation period of the subject in the second embodiment of the present invention. FIG. 12 is a diagram showing the shift amount of the subject photographing angle in the second embodiment of the present invention. FIG. 13 is a sequence time chart according to the second embodiment of the present invention. FIG. 14 is a diagram showing the relative positional relationship between the imaging device and the orientation of the face of the subject in the first embodiment of the present invention.

  First, the operation of the main part performed by the control unit 20 will be described using the flowchart of FIG.

  In step S401, the control unit 20 determines whether or not the MAINSW (one of the imaging device operation unit 6 in FIG. 1) of the imaging device is turned on. If not, the control unit 20 stands by in this step. Thereafter, when the MAINSW is turned on, the process proceeds to step S402, where it is determined whether or not a mode for photographing a rotating subject (hereinafter referred to as a rotating body photographing mode) is set. If the rotating body shooting mode is not set, the process returns to step S401.

  Specifically, the setting of the rotating body photographing mode may be selected by the mode dial 3 of the imaging apparatus or may be selected from the MENU screen of the imaging apparatus. In step S403, shooting conditions are set. Specifically, the number of shots is set, and this setting will be described in detail with reference to FIG.

  FIGS. 9A and 9B show a shooting condition setting screen displayed on the display unit 5 in FIG. FIGS. 9A and 9B show a state in which the subject is viewed from above, and the state in which the subject is facing downward in the drawing is the front of the subject. FIG. 9A shows a setting screen when the number of shots is set to eight.

  The photographer operates the rotation operation unit of the operation unit 6 to select the number of shots, and then determines the number of shots by pressing the determination operation unit. A mark ▼ around the subject indicates which angle of the subject is to be photographed. That is, in the case of FIG. 9A, the subject is photographed every 45 degrees of rotation.

  Similarly, FIG. 9B shows a case where the number of shots is set to 6, and shows that the subject is shot every 60 ° rotation. In step S403, it is also possible to set whether or not to rearrange images taken on a setting screen (not shown) in the order of rotation. Details will be described later.

  Returning to FIG. 8 (flowchart), in the next step S404, the state of the release button 2 of the image pickup apparatus is detected, it is determined whether or not the shooting preparation operation has been started by the photographer, and the switch SW1 is switched. If it is not ON, it waits at this step. After that, when turned ON, the process proceeds to step S405, where AF (autofocus) and AE (photometry) are started. By this operation, the driving of the focus lens (not shown) and the shutter time and aperture value of the imaging apparatus are determined.

  In step S406, it is determined whether the subject is rotating. In the present embodiment, the AE sensor included in the AE unit 26 is a solid-state imaging device such as a CCD or CMOS sensor as described above, and can detect a subject based not only on the brightness of the subject but also on the face and color recognition. . After recognizing the face of the main subject, the rotation detection unit 27 turns off the face recognition because the subject is rotating, and recognizes the rotation of the main subject when the face is recognized again.

  In order to avoid erroneous detection of rotation when a subject facing the direction of the imaging device 1 turns sideways or behind once and turns to the direction of the imaging device 1 again, the interval at which the rotation detection unit 27 recognizes the face is set. If it is 1 second or longer, it may be controlled to determine that the subject is not rotating. In step S406, the rotation detection unit 27 records the rotating subject image in the buffer memory 28 at about 30 to 60 fps. Since the spin speed of a figure skater is 3 revolutions / s for a fast athlete, about 10 to 20 images are recorded during one revolution.

  Further, the rotation detection in step S406 may be performed by detecting the same posture of the subject twice. If rotation detection is not performed, the process proceeds to step S407, and the photographer is notified that rotation detection is impossible by blinking the rotation detection mark 41 on the in-viewfinder display 40 shown in FIG. Become.

  In the next step S408, as shown in FIG. 11, the time required for one rotation of the subject whose rotation is recognized, that is, the rotation period T (s) is calculated. Also, according to the number of shots set in step S403, the subject angle shift amount t (FIG. 12) for the second and subsequent shots, that is, how much the shooting timing is shifted with respect to the front of the subject is calculated. To do. This shift amount is obtained by T / N, where T (s) is the rotation period of the subject and N is the number of shots set in step S403.

  In the next step S409, the rotation detection mark 41 shown in FIG. 10 is turned on in the viewfinder to notify the photographer that the rotation of the subject has been detected. Note that the order of step S409 and step S408 may be interchanged.

  When the calculation of the rotation period and the notification to the photographer are completed, in the next step S410, it is determined whether or not the switch SW2 of the release button 2 of the imaging device is ON. Here, if it is not turned on yet, the process returns to step S406 again, and rotation detection is continued. Thereafter, when SW2 is turned on, the process proceeds to step S411, and in accordance with the rotation period calculated in step S408, a shooting operation is performed at a position where the rotating subject faces right toward the image pickup apparatus 1. That is, even if SW2 is ON, the control unit 20 does not immediately execute the shooting operation, and the control unit 20 starts the shooting operation in synchronization with the timing when the subject turns to the right toward the imaging device 1. Adjust the X section shown in.

  In this embodiment, for ease of understanding, as shown in FIG. 11, the first image is taken at the timing when the subject turns right toward the imaging apparatus 1, but any angle is acceptable even if the first image is in front. It may be. Further, it may be controlled to start the photographing operation when the switch SW2 is turned on in step S410.

  In step S412, AF and AE are performed again for the second and subsequent images. FIG. 13 shows a sequence time chart.

  FIG. 14 shows the relative positional relationship between the imaging device 1 and the orientation of the face of the subject. 14A shows an example of the orientation of the subject at the time of shooting the first image, and FIG. 14B shows an example of the direction of the subject at the timing of AF and AE (B section in FIG. 13) between the first and second images. Yes.

  Assuming that the frame speed of the imaging apparatus in this embodiment is 3 frames / s, as described above, it is synchronized with the spin speed of the figure skating player. For this reason, at the timing of AF and AE between the first and second shots (B section in FIG. 13), as shown in FIG. 14B, the subject does not necessarily have the orientation of the first face. It is assumed that they do not face the matching direction. Therefore, in the rotation detection in the next step S413, the rotation detection unit 27 records in the buffer memory 28 an image in which the subject is not facing in the direction matching the first photographed image.

  The image recorded in step S406 corresponding to the same timing as the image recorded here is compared. As a result of the comparison, if there is a deviation in the posture (rotation angle) of the subject, it is determined that the rotation cycle of the subject has changed, and the process proceeds to the next step S414 to recalculate the rotation cycle and shift amount of the subject. To do.

  If the image acquired in step S406 is different from the image acquired in S413, it is determined that the subject has stopped rotating or the spin type has been changed, and the process returns to step S404.

  Subsequently, in step S415, the control unit 20 adjusts the Y section in FIG. 13 based on the period shift amount calculated in step S414, and executes the second image capturing operation.

  In the next step S416, it is determined whether n / N is 1 or not, where n is the cumulative number of shots and N is the number of shots set in step S403. If n / N is not 1, it is determined that the number of shots set in step S403 has not been reached, and the operations after step S412 are repeated. When n / N becomes 1, it is determined that the number of shots set in step S403 has been reached, and the series of operations is terminated.

  In this embodiment, since the frame speed of the imaging apparatus is 3 frames / s, the number of shots per rotation is one, but if the frame speed is fast, the number of shots per rotation can be increased. It is. For example, if the frame speed is 6 frames / s, two images can be captured per subject rotation. However, in this case, the image acquired at the first rotation is recorded in the recording unit 29 in the order of the 0 ° and 180 ° subject images, and the second rotation at 45 ° and 225 °.

  Therefore, after the photographing is finished, an image displayed on the display unit 5 by pressing a playback button (one of the imaging device operation unit 6 in FIG. 1) is 0 degrees, 180 degrees, 45 degrees, 225 degrees, and so on. It becomes order and becomes difficult to see. In such a case, it is possible to reproduce an image in accordance with the rotation order of the subject by setting whether or not to rearrange the captured images in the rotation order of the subject when setting the shooting conditions in step S403 of the flowchart shown in FIG. Become.

As described above, the photographer performs a simple shooting operation on the rotating subject.
There is an effect that images of various orientations can be easily taken. In particular, since the camera automatically controls when a plurality of shootings are performed at a time, there is an effect that shooting can be performed without requiring the photographer himself / herself to use advanced technical techniques.
