As shown in Figure 7, want being taken the photograph body A1 as mainly being taken the photograph under the situation that body takes (Fig. 7 (a)) at cameraman K1, when fitful wind to the right direction (arrow Y1) taken the photograph body A1 direction inclination to the right and rocked (Fig. 7 (b)) when blowing.At this moment, taken the photograph body A1 in order to take in the substantial middle in photography zone, cameraman K1 the position of camera head 1 (pan operation) according to being taken the photograph moving of body A1.As a result, the photography zone of camera head 1 becomes the regional F2 of photography from the regional F1 that photographs.
Afterwards, taken the photograph body A1 and move and will get back to reset condition (Fig. 7 (c)) to (arrow Y2) towards left owing to fitful wind stops to make, thus the position that cameraman K1 makes camera head 1 in the opposite direction (left to) move.As a result, the photography zone of camera head 1 becomes the regional F3 of photography from the regional F2 that photographs.
Then, taken the photograph body A1 and further moved (Fig. 7 (d)) to (arrow Y2) from the position of reset condition towards left owing to inertia.Therefore, cameraman K1 is moved further the position of camera head 1, thereby the photography zone of camera head 1 becomes the regional F4 of photography from the regional F3 that photographs.
Through being taken the photograph the operation of photographing in the body A1 by what cameraman K1 carried out following the tracks of like this, while watch the live view image that is shown on the display part 7 to photograph till the action to cameraman K1, can generation time poor.Specifically, as shown in Figure 9, cameraman K1 is moved to and camera head 1 is moved can generation time postpone the (time T of Fig. 9 from taking the photograph body A1 1).And then cameraman K1 is difficult to making wind-engaging mobile quilt and takes the photograph under the state of central authorities that body A1 is fixed in the photography zone and follow the tracks of, the result, and the moment that arrives maximum displacement postpones the (T of Fig. 9 2).For example, shown in Fig. 8 (a) and Fig. 8 (b), owing to taken the photograph body A1 towards right-hand to mobile (image W 1→ image W 2), thereby cameraman K1 through follow the tracks of taken the photograph body A1 move dollying device 1, make the photography zone move the (moment t of Fig. 9 1～t 2).
Afterwards, shown in Fig. 8 (b) and Fig. 8 (c), (moment t of Fig. 9 when fitful wind stops, being taken the photograph body A1 and will get back to reset condition towards left to moving 2～t 3) time, making under its situation consistent with the displacement of being taken the photograph body A1 (direction of advance is reverse each other) at cameraman K1 towards the displacement in right-hand photography zone to the camera head 1 that moves, quilt is taken the photograph body A1 becomes image (the image W that is positioned at substantial middle 3).
Then, shown in Fig. 8 (d)～Fig. 8 (e), further moved the back towards right-hand to (arrow b2) to mobile (image W towards left owing to take the photograph body A1 3→ image W 4→ image W 5), thereby cameraman K1 through follow the tracks of taken the photograph body A1 move dollying device 1, make the photography zone move the (moment t of Fig. 9 3～t 6).At this moment, intersected (the moment t of Fig. 9 once more owing to take the photograph the regional middle position of photography of middle position and the camera head 1 of body A1 6), thereby photograph and taken the photograph image (the image W that body A1 is positioned at substantial middle 5) (with reference to Fig. 8 (e)).The displacement in the photography zone when displacement and the cameraman K1 that then, is taken the photograph body A1 moves camera head 1 is mutual approximate period property.Here, it is the general expression that in displacement for just and between negative moving back and forth for approximate period property.
Like this; Make camera head 1 that camera head 1 has been carried out under the reciprocating situation with predetermined amplitude at cameraman K1; When the quilt that moves as the moving direction towards camera head 1 is taken the photograph body A1, mainly taken the photograph body configuration part 104 and will be taken the photograph body A1 and be set at the main of cameraman K1 expectation photography and taken the photograph body.Thus; Being taken the photograph that body A1 receives wind etc. under the fierce situation that moves; Even when not determining photography composition, mainly taken the photograph body configuration part 104 and also can be judged the tracking action of cameraman K1, can cameraman K1 expectation main be taken the photograph body and be set at the object of in photography, following the tracks of.

(execution mode 2)
Then, execution mode 2 of the present invention is described.The camera head that execution mode 2 of the present invention relates to also has the orientation detection portion of detection orientation.And in the action that the camera head that execution mode 2 of the present invention relates to carries out, it is different with above-mentioned execution mode 1 mainly to be taken the photograph body candidate determination processing.Therefore, in following, the structure of orientation detection portion is described, the main body candidate determination processing of being taken the photograph of the action of the camera head that execution mode 2 of the present invention relates to is described afterwards.In addition, in the accompanying drawing record, same section is enclosed same numeral.
Figure 12 is the block diagram that the structure of the camera head 100 that execution mode 2 of the present invention relates to is shown.Shown in figure 12, camera head 100 has: image pickup part 2, acceleration detecting section 3, timer 4, illuminating part 5, operation inputting part 6, display part 7, touch panel 8, storage part 9, control part 10 and orientation detection portion 110.
Orientation detection portion 110 is made up of geomagnetic sensor.Orientation detection portion 110 detects and preestablishes the appointment orientation in camera head 100.Specifically; Orientation detection portion 110 is through detecting when the vertical direction of the horizontal direction of the transverse direction of display part 7 images displayed and camera head 100 earth magnetism about equally time the and the component of horizontal direction, and detection is when the orientation of the camera head 100 during as the reference bearing with the optical axis O1 of image pickup part 2.
Then, the main body candidate determination processing of being taken the photograph that the camera head 100 that this execution mode 2 is related to carries out describes.Figure 13 illustrates the main flow chart of being taken the photograph the summary of body candidate determination processing (the step S106 of Fig. 4) that camera head 100 that this execution mode 2 relates to carries out.
Shown in figure 13, moving direction detection unit 102 is judged the acceleration (step S401) that in camera head 100, produces according to acceleration detecting section 3 detected testing results.Being judged to be in z direction (optical axis O1 direction) at moving direction detection unit 102 does not have under the big situation of the acceleration of acceleration ratio x direction (horizontal direction) of acceleration (step S402: be), y direction (vertical direction) (step S403: be); When moving direction detection unit 102 is judged to be the testing result cyclic variation of acceleration of x direction or y direction (step S404: be), mainly being taken the photograph body couple candidate detection portion 103 will have mobile mobile object to survey to being taken the photograph body candidate (step S405) in the live view image that display part 7 shows.
Figure 14 is the figure of schematic illustration moving direction detection unit 102 situation when judging the mobile status of camera heads 100.Figure 15 observes the vertical view taken the photograph body from Figure 14 to looking the A direction.Figure 16 observes the end view taken the photograph body from Figure 14 to looking the B direction.Figure 17 is the speed of schematic illustration cameraman K1 camera head 100 when camera head 100 is moved and the figure of acceleration detecting section 3 detected relationship with acceleration.In Figure 17 (a), transverse axis t express time, longitudinal axis v representes the speed of camera head 100, curve L 11The velocity variations of expression camera head 100.And, in Figure 17 (b), transverse axis t express time, longitudinal axis a representes acceleration.And, in Figure 17 (b), curve L X1The acceleration of the horizontal direction of expression camera head 100, curve L Y1The acceleration of the vertical direction of expression camera head 100, curve L Z1The acceleration of the optical axis direction of expression camera head 100.In addition, in Figure 14 and Figure 15, consideration will make camera head 100 just be set to situation about moving towards right-hand, with making camera head 100 be set at negative towards left to situation about moving.
Like Figure 14～shown in Figure 16; Taken the photograph under the irregular mobile situation of body A1; Cameraman K1 follows the tracks of while the live view image of watching display part 7 to show and is taken the photograph body A1, thereby the acceleration of the vertical direction that produces in the camera head 1 shows the value bigger than the acceleration of horizontal direction.Specifically, shown in figure 17, at cameraman K1 according to mobile make under the situation that camera head 1 moves of being taken the photograph body A1 (t constantly 1～t 2, moment t 5～t 6), the acceleration of acceleration detecting section 3 detection level directions and vertical direction, and detect the big value of acceleration of the acceleration ratio horizontal direction of vertical direction.And, stopped under the situation about moving of camera head 100 (t constantly at cameraman K1 3～t 4, moment t 7～t 8), the acceleration of acceleration detecting section 3 detection level directions and vertical direction, and detect the big value of acceleration of the acceleration ratio horizontal direction of vertical direction.And cameraman K1 moves according to the mobile camera head 100 that makes of the approximate period property of being taken the photograph body A1, thus the acceleration cyclic variation of acceleration detecting section 3 detected horizontal directions and vertical direction.
As stated; Under the big situation of the acceleration of the acceleration ratio horizontal direction that does not have acceleration, vertical direction on the optical axis O1 direction; When the testing result of the acceleration of horizontal direction and vertical direction is periodically the time, is mainly taken the photograph body configuration part 104 and will be taken the photograph mainly in the live view image that display part 7 shows that body couple candidate detection portion 103 is detected mainly to be taken the photograph the body candidate and be set at mainly and taken the photograph body.
After step S405, step S406 carries out the processing identical with step S205 with above-mentioned step S204 with step S407, thereby omits explanation.After step S407, camera head 100 is got back to main routine shown in Figure 4.
The testing result of acceleration that moving direction detection unit 102 in step S404 is judged to be x direction or the y direction of camera head 100 is not periodic situation (step S404: not) describe.In this case, moving direction detection unit 102 judges whether the testing result of orientation detection portion 110 is periodic (step S408).The testing result that is judged to be orientation detection portion 110 at moving direction detection unit 102 is (step S408: be) under the periodic situation, and camera head 100 is transferred to step S405.On the other hand, the testing result that is judged to be orientation detection portion 110 at moving direction detection unit 102 is not (step S408: deny) under the periodic situation, and camera head 100 is got back to main routine shown in Figure 4.
Figure 18 is the figure of schematic illustration moving direction detection unit 102 situation when judging the mobile status of camera heads 100.Figure 19 is the figure of relation of speed and the orientation detection portion 110 detected testing results of the camera head 100 of schematic illustration cameraman K1 when camera head 100 is moved.In Figure 19 (a), transverse axis t express time, longitudinal axis θ representes the testing result of orientation detection portion 110, curve L 11The velocity variations of expression camera head 100.And in Figure 19 (b), transverse axis express time, the longitudinal axis are represented the testing result of orientation detection portion 110, curve L 12The variation of the testing result of expression orientation detection portion 110.In addition, in Figure 18, consideration will make camera head 100 just be set to situation about moving towards right-hand.
Like Figure 18 and shown in Figure 19, taken the photograph under the situation that body A1 approximate period property moves, taken the photograph body A1 while the live view image that cameraman K1 watches display part 7 to show is followed the tracks of, thereby orientation detection portion 110 detected testing results are approximate period property.Specifically, shown in figure 19, at cameraman K1 according to mobile make under the situation that camera head 100 approximate period property move of being taken the photograph body A1 (t constantly 1～t 2, moment t 5～t 6), the 110 detected numerical value approximate period property variations of orientation detection portion.
Like this; Testing result at the acceleration of the x of camera head 100 direction or y direction is not under the situation of approximate period property; When the testing result approximate period property variation of orientation detection portion 110, mainly taken the photograph body configuration part 104 and will be taken the photograph mainly in the live view image that display part 7 shows that body couple candidate detection portion 103 is detected mainly to be taken the photograph the body candidate and be set at mainly and taken the photograph body.
Moving direction detection unit 102 in step S402 is judged to be the situation that on acceleration detecting section 3 detected z directions, do not have acceleration change, and (step S402: moving direction detection unit 102 is judged to be situation (the step S403 :) do not describe that the axial acceleration of acceleration detecting section 3 detected y is not more than the acceleration of x direction not) and in step S403.In this case, camera head 100 is got back to the main routine of Fig. 4.
