Additionally, the view data that interim storage is exported from image pickup part 3.In the present embodiment, it was stored with before each second 0.5 second view data (due to being 60fps, therefore, store 30 frames amount view data).Additionally, as above Described, according to each region 3Aa, tracking part 15 judges that subject is to move or static, therefore, store the judgement As a result history.

Then, the action of present embodiment is illustrated using Fig. 2 to Fig. 4.First, the one of subject is illustrated using Fig. 3 Individual example and focusing now.In figure 3, the change of longitudinal axis express time, moment T0 are present, moment T1 Before being 0.1 second, before moment T2 is 0.3 second, before moment T3 is 0.5 second.Imaging apparatuss 3A be divided into (A, 20 (30 are divided in Fig. 1 (b), and illustrate the example for being divided into 20 herein) of a)～(E, e).

Tracking part 15 on the basis of to a certain moment T3 before certain hour, according to each region to moment T3 and The view data of moment T1 is compared, and judges that subject is to move or static in each region.Equally, according to Each region compares the view data of moment T3 and moment T2, also has the view data of moment T3 and moment T0, Judge that subject is to move or static in each region.In addition, be not limited to the moment on the basis of moment T3 judging In each region subject be motion or it is static, for example, it is also possible on the basis of moment T0 (present) respectively with when Carve T1, T2, T3 to be compared.

In the example shown in Fig. 3, in moment T3, Zone Full (A, a)～(E, e) of imaging apparatuss 3A Subject it is static, in moment T2, only region (B, b) motion, other regions are static, in moment T1, only area Domain (C, c), (D, c), (B, b) motion, other regions are static.

At present, moment T0 is located at, user has carried out touch operation to region (D, b).Known by eyes Do not play till actually being touched, there is the delay of about 0.5 second or so, it is, therefore, usually considered that user be with when The subject that quarter T3 (before 0.5 second) is present in region (D, b) is that the object being intended to is touched.In figure In example shown in 3, it is present in the subject in region (D, b) in moment T2, T1, T0 in moment T3 Do not move, remains stationary state, therefore the coordinate (D, b) in the region to being touched carries out focus operation, meanwhile, Correct exposure is controlled into, shutter release movement is carried out.

Consequently, it is possible in the example shown in Fig. 3, judge that the subject in touched region is to move or static, In the case where result of determination is static, the region to being touched is focused, and directly carries out shutter release movement.

Then, another example of subject and focusing now are illustrated using Fig. 4.In the example in figure 3, Petting Area The subject in domain is static, but, in the example in fig. 4, the subject motion of touch area.Even if in the diagram, Also as Fig. 3, the change (moment T0～moment T3) of longitudinal axis express time, imaging apparatuss 3A by (A, a)～ (E, e) is constituted.

In the example in fig. 4, the also moment on the basis of moment T3 of image processing part 5, when comparing according to each region Carve view data, the also view data of moment T3 and moment T2, moment T3 and the moment of T3 and moment T1 The view data of T0, judges that subject is to move or static in each region.

At present, moment T0 is located at, user has carried out touch operation to region (C, b).As described above, passing through Eyes are identified playing till actually being touched, the delay for having about 0.5 second or so, it is, therefore, usually considered that using Family is carried out with the object that the subject being present in region (C, b) in moment T3 (before 0.5 second) is intention Touch.In the example shown in Figure 4, moment T3 be present in the subject in region (C, b) moment T2, T1 (at least before 0.5 second～before 0.1 second till during) is static, but (at 0.1 second during moment T1 to T0 Before～now till during) motion, move to region (D, b).Therefore, to move destination region coordinate (D, b) (also referred to as AF regions) carries out focus operation, and controls into correct exposure, carries out shutter release dynamic Make.

Consequently, it is possible in the example shown in Figure 4, judge the subject in touched region in cake slightly before It is whether static, focus operation etc. is carried out to the subject in just existing region, shutter release movement is carried out.That is, In order to in touch area (C, b) just be moment T1 till static subject carry out focus operation etc., The motion of delay and subject in view of vision, the region that AF is detected is altered to from touch area (C, b) AF regions (D, b).

Then, the action of present embodiment is illustrated using the flow chart shown in Fig. 2.According to being stored in memorizer 25 Program performs the flow process by CPU21.When shooting action starts, the flow process starts.First, judge touch panel Whether portion 17 is touched (S1).When shooting action starts, export from image pickup part 3 according to the ratio of 60 frame per second View data, carries out live view in display part 7 according to the view data and shows.In this step, according to from tactile Whether the touch detection signal determining user for touching panel part 17 touches the display picture of display part 7.

Result of determination in step s 13 is for, in the case of being, tracking is present in touched from before the 2nd certain hour Subject (S15) in the region touched.Due in the region for being touched from before 0.5 second to before 0.1 second, subject It is static, therefore follow the trail of the subject.Follow the trail of when, partial vector may also be employed, as illustrated in fig. 6 as enter Row is followed the trail of, but, in the present embodiment, view data during by being touched before 0.5 second and present The view data of adjacent area in the region for being touched be compared, it is adjacent so as to pass through to judge that subject is present in Which it is tracked in region.Due to subject touch it is tight before move, therefore be present in touch area Probability in adjacent area is high, in addition, can be tracked at short notice compared with being tracked using partial vector.

On the other hand, in the case that result of determination in step s 13 is no, tracking is present in the 1st certain hour Subject (S17) in front touched region.As the result of determination in step S13 is no and certain from the 2nd Before time (in the present embodiment for 0.1 second before) play motion, thus exist move to it is adjacent with touch area Region away from region probability.Therefore, as illustrated by using Fig. 6, tracking part 15 is using each frame View data, carries out the tracking of subject, obtains that present which frame has subject.

Result of determination in the step s 7 in the case of no, or, the feelings that result of determination in step s 9 is yes Under condition, or, it is when the tracking of subject has been carried out in step S15 or S17, identical with the 1st embodiment, Focused and carried out shutter release (S21).When focus operation and shutter release movement has been carried out, terminate the stream Journey.

Thus, in the 2nd embodiment of the present invention, (it is being 0.5 in the present embodiment from the 1st certain hour Second) before to before the 2nd certain hour (being 0.1 second in the present embodiment) during touch area subject it is static Situation and from before the 2nd certain hour touch area subject move in the case of, in step S15 and S17 Middle change method for tracing.Therefore, it is possible to basis from the moment (present) for being touched play the 1st certain hour it Before during subject motion selecting appropriate method for tracing.

Additionally, as described above, CPU21 has as determining the work(of the determining section of the subject that will be focused Can, the determining section is focused to the subject being present in before certain hour in touched region (reference S15)。

In addition, in the present embodiment, if the 1st certain hour is 0.5 second, if the 2nd certain hour is 0.1 second, It is however not limited to this, or other times, as long as the 1st certain hour is wanted touch from user and is started to reality Border touched till or so time delay time, as long as the 2nd certain hour is shorter than the 1st certain hour Time.1st and the 2nd certain hour can coordinate the characteristic of user to be changed.Additionally, adopting Fig. 6 In illustrated method for tracing (S17 in Fig. 5), although carried out using the view data exported according to every frame Follow the trail of, it is however not limited to this, can be every two frame, or every three frame, suitably can be changed.Additionally, Before the 2nd certain hour it is static in the case of, the tracking being not limited in adjacent area, naturally it is also possible to carry out base In the accumulative tracking for surmounting adjacent area of the partial vector as illustrated by using Fig. 6.

Additionally, as the 1st variation of present embodiment, in step s 13, can be to from now on to the 1st During before certain hour, static subject more than certain hour is tracked.Now, by tracking part 15 Subject to being present in touch area is tracked, and is judged according to the tracking result.

(the 3rd embodiment)

Then, the 3rd embodiment of the present invention is illustrated using Fig. 7 to Figure 10.In the 1st and the 2nd embodiment In, to the subject being present in before the 1st certain hour corresponding with the time delay that user touches in touch area It is tracked, is controlled to focus which.On the other hand, in the 3rd embodiment, touched to being present in Time in the region touched most long subject is tracked, and is controlled to focus which.

Structure in present embodiment is identical with the structure of the block diagram shown in Fig. 1 of the 1st embodiment, therefore, omit Detailed description.First, the action of present embodiment is illustrated using Fig. 9 and Figure 10.

In the example shown in Fig. 9, moment T0 represents that user touches the moment of touch surface plate portion 17.Moment T25 It is the moment for shifting to an earlier date the time suitable with the 1st certain hour than moment T0.Two field picture F1 is exported in moment T25, Afterwards, according to two field picture F2 (moment T24), two field picture F3 (moment T23), two field picture F4 (moment T22) Order be sequentially output two field picture.

In the present embodiment, for two field picture on the basis of the region for being touched in the two field picture F1 of moment T25 F1, F2, F3, F4 ... calculate partial vector.That is, obtain being present in for moment T25 being shot in touch area Body is moved to which in two field picture F2, F3, F4 ....Equally, with the two field picture F2 of moment T24 In the region for being touched on the basis of, for two field picture F2, F3, F4 ... calculate partial vector.That is, when obtaining The subject being present in touch area for carving T24 is transported to which in two field picture F2, F3, F4 ... It is dynamic.Next, for two field picture F3, F4 ... also obtain the fortune of the subject being present in touch area in the same manner It is dynamic.

It is present in an example of the motion of the subject in the touch area using Figure 10 explanations.Assume in moment T0, Touch region (B, b).Primary search is the tracking on the basis of two field picture F1, follows the trail of moment T25's The motion of the subject in the region (B, b) for being touched.It is present in region (B, b) in moment T25 subject A, It is present in region (B, b) in moment T24 subject A, is present in region (C, c) in moment T23 subject A, It is present in region (C, c) in moment T22 subject A, is present in region (D, c) in moment T21 subject A. Therefore, the Search Results of the 1st time be the touch area time of staying of subject A be equivalent to the time of 2 frames.

The search of the 2nd time is the tracking on the basis of two field picture F2, is followed the trail of in the region (B, b) of moment T24 The motion of subject.It is present in region (B, b) in moment T24 subject A, deposits in moment T23 subject A It is region (C, c), is present in region (C, c) in moment T22 subject A, in moment T21 subject A It is present in region (D, c).Therefore, the Search Results of the 2nd time be subject A the touch area time of staying be phase When in the time of 1 frame.

The search of the 3rd time is the tracking on the basis of two field picture F3, is followed the trail of in the region (B, b) of moment T23 The motion of subject.It is present in region (B, b) in moment T23 subject B, deposits in moment T22 subject B It is region (C, b), is present in region (C, c) in moment T21 subject B.In addition, in figure, while Also show that the position of subject A.In fig .9, although the specific example of two field picture F1～F3 is shown, but when Carve T0 it is tight before, similarly carry out the tracking of subject being present in touch area.Therefore, search the 3rd time Hitch fruit be touch area time of staying of subject B be equivalent to the time of 1 frame.

Return Fig. 9, when for the whole two field pictures before the moment T0 for being touched, obtained be present in it is tactile After touching the time of staying of subject in region, then, calculated according to vector in each frame, carry out what is should focused The determination in AF regions.When i.e., on the basis of above-mentioned two field picture F1, F2, F3, F4 ..., it is determined that being stored in In subject in touch area, the time of staying most long subject is in the region existing for moment T0.In Figure 10 In shown example, be only F1, F2, F3 these three, but, in this case, subject A exists than subject B In touch area, residence time is longer, therefore, the region that subject A of moment T0 is present is defined as into AF areas Domain.

When AF regions are determined, the AF regions are focused.That is, the figure according to the AF regions determined As the contrasting signal of data carries out the focusing of camera lens 1.
