At step S318, judge whether the content of counter B_COUNTB is more than 75.Suppose from a series of processing cycle that step S302 plays till the step S321 described later be 2mS, judge from starting exposure beginning acts of determination whether passed through 150m second.Herein, if under the situation of process not, enter step S321.Judging under the situation of process, enter step S319.And, in the present embodiment, set " 75 " this value, but be not limited to this value (time), also can be other value (time).
At step S319, judge whether the content of counter B_COUNTB equals 75.If equal 75, enter step S320 described later, otherwise enter step S321.Add this judgement herein and be because the exposure among the step S320 described later begins to judge the change of permission time and only carry out cause once.
At step S320, exposing begins to judge the change of permission time.The judgement that is about to be set in the critical parameter configuration part 22 allows temporal information to change the operation of (increasing).Thereby, by exposure beginning timing controlled alleviate and rock on one side, making exposure begin to allow to be more prone to carry out on one side, as a result of, estimate to take place can shorten slightly time delay.
At step S321, judge what step S302 started and rock the sense cycle timer and whether passed through the stipulated time.If process then turns back to step S302, circulation is carried out hereto in a series of processing described in Figure 15.Timer time herein for example can be thought of as 2mS or 1mS.
Figure 16 was 0 process flow diagram of judging.So-called cross 0 and judge, be meant that corresponding to image planes X, the information of rocking of any one party of Y-axis is passed 0 grade of state (speed=0) afterwards, the judgement that the opposing party exposes and begins to allow under the situation of equally also passing 0 grade of state within the official hour.
In Figure 16, at first, began 0 and judged.At step S401, judge whether the vibrating state value (X) of prediction passes 0 grade.It is according to carrying out from the 2nd output of rocking prediction and calculation portion 19.Whether it is judged at the described longitudinal axis of aftermentioned Figure 17 is ± 0 grade, that is judges whether rock angular velocity once was 0.When passing 0, enter step S405 described later.
When passing 0, at step S402, F_XLAG is set at " 1 " with X-direction vibrating state sign.
At step S403, judge whether Y direction vibrating state sign F_YFLAG is " 0 ", that is, judge whether the vibrating state value of being predicted (Y) (beginning in the permission time in exposure judgement described later) is the state that passes (intersection) 0.When not passing but under the situation of " 0 ", enter step S404.In addition, when not being " 0 ", that is pass 0 and be under the situation of " 1 ", enter aftermentioned step S414.
At step S404, the vibrating state value of accepting to be predicted (Y) is not passed 0 grade, the timer that resets/start and be used to expose and begin to judge.
At step S405, judge whether the vibrating state value of being predicted (Y) passes 0 grade.This is according to carrying out from the 1st output of rocking prediction and calculation portion 18.Whether judgement is ± 0 grade at the longitudinal axis shown in Figure 17, that is judges whether rock angular velocity once was 0.When not passing 0, enter step S409 described later.
When passing 0, at step S406, F_YFLAG is set at " 1 " with Y direction vibrating state sign.
Secondly,, judge whether directions X vibrating state sign F_XFLAG is " 0 ", that is judge whether the vibrating state value of being predicted (X) (beginning to judge in the permission time Δ t in exposure described later) is to pass 0 state at step S407.If not " 0 ", that is pass 0 and be under the situation of " 1 ", enter step S414 described later.When being " 0 ", enter step S408.
At step S408, the vibrating state value of accepting to be predicted (X) is not passed 0 grade, the timer that resets/start and be used to expose and begin to judge.
At step S409, read the exposure that is set in the critical parameter configuration part 22 and begin to judge the permission temporal information.
At step S410, judge whether the time at step S404 or the timer that starts is that the exposure of being read began to judge more than the permission time in step S408.That is, judge to begin to judge in exposure whether the vibrating state value (X), (Y) that are predicted in the permission time all once passed 0 grade.Herein, if the time not then, enter RETURN (returning).When being exposure when beginning to judge that the permission time is above, just judge it is to rock big state, at step S411, S412 is changed to " 0 " with rock direction Status Flag F_XFLAG, the F_YFLAG of X, Y.0 the state that do not pass is rocked in this expression.
At step S413, stop at the timer that starts among step S404, the S408.This is to finish because departed to rock little state or begin judgement because of exposure described later.
Secondly, in step S403 when Y Directional Sign F_YFLAG be the situation of " 1 " and in step S407 when directions X sign F_XFLAG be that the situation of " 1 " describes.Make these and judge and just to mean that the vibrating state value that X and Y are predicted all passes 0 grade in exposure begins the judgement time, be judged to be and begin exposure.Therefore, at step S414, preceding curtain moved begin to allow sign F_GOFLAG to be set at " 1 ".Thereby,, allow the exposure beginning at the step S32 of Fig. 8.Enter step S413 thereafter.
Figure 17 is illustrated in the action example that mistake 0 illustrated in fig. 16 is judged with waveform, and the vibrating state value ω X of image planes X-direction, the vibrating state value ω Y of image planes Y direction are drawn at grade.Among the figure, the longitudinal axis be rock angular velocity [degree/second], transverse axis is time t.
In Figure 17, though before timing T ω X and ω Y respectively pass respectively ± 0 grade once because at time width Δ t, that is, exposure begin to judge also have in the permission time side do not pass ± 0 grade, therefore just do not allow exposure to begin.But,, be set at " 1 " so will indicate F_GOFLAG because satisfy condition in the timing of time T.
In the above-described embodiment, select to inform under the situation of pattern and select to inform under the situation of pattern and exposure actions pattern that form is informed in change.For example, as rocking countermeasure, with discharge time-controlled situation and compare, before only carrying out beginning to indicate based on exposure rock the informing of testing result the time, rocking before making exposure begin to indicate informed stricter more than original vibrating state, perhaps shorten the operation of rocking change cycle of informing and so on, impel actual exposure action to note more.
Therefore, even do not discharging under the time-controlled situation, also can reduce and rock photo.
And, with utilizing time-controlled example to alleviate pattern and be illustrated to rocking, but as mentioned above, even under the situation that makes the displacement of photographic optical system or imaging apparatus, similarly, if make only set inform pattern as rock under the situation that alleviates pattern and set inform pattern with rock alleviate the pattern conduct rock under the situation that alleviates pattern to rock the form of informing different, also can obtain same effect.
According to the present invention, selecting to inform under the situation of pattern and selecting to inform pattern and rock under the situation that alleviates pattern that form is informed in change, therefore can carry out suitable informing according to the setting pattern, rocks photo thereby reduce.
