It is the camera lens intrinsic information that reads in the open f-number of interchangeable lens 100 and focus information etc. via telecommunication circuit 273 from camera lens CPU 111 that the shot information of step # 7 is read in.In this step, under the situation of having set the B door model, read in this information.
Then, whether set the judgement (#9) of B door model.Because in step # 7, read in screening-mode, so whether set the judgement of B door model as the screening-mode that reads in.
Judged result at step # 9 is not set under the situation of B door model, carries out photometry/exposure computing (#11).In this step, carry out photometry by 211 pairs of subject brightness of photometry sensor, the computing exposure uses this exposure to carry out the computing of exposure control values such as shutter speed or f-number according to screening-mode/shooting condition.
Judged result at step # 9 is to have set under the situation of B door model, and input update time (cycle of output image data repeatedly) (#31).The back uses Fig. 5 to narrate the input of this update time.After finishing the input of update time, enter step #13.Under the situation of B door model, irrespectively operate the switch that carries out shutter 213 with photometry, so the not photometry of execution in step #11/exposure computing by the user.
Then, show photographing information (#13) on the LCD monitor 26 overleaf.So-called photographing information is meant screening-mode/shooting condition of reading in etc. and the shutter speed of computing in step #11 or the exposure control value of f-number etc. in step #7.Setting under the situation of B door model as screening-mode, as shown in Figure 9, the B door model shows 301 and show that 302 are presented on the back side LCD monitor 26 with other photographing information update time.
After showing photographing information, next, judge whether the playback switch that links with broadcast button 38 is to connect (#17).Play mode is, when having operated broadcast button 38, reads the view data that is stored on the recording medium 277 and it is presented at pattern on the back side LCD monitor 26.In judged result is that playback switch is under the situation about connecting, and carries out playback action (#33).
Judged result at step # 17 is that broadcast button does not have under the situation of connection, judges with the menu switch of menu button 37 interlocks whether connect (#19).In this step, judge whether to have operated menu button 37 and set menu mode.In judged result is under the situation of menu switch connection, carries out the menu demonstration overleaf on the LCD monitor 26 and carries out menu setting action (#35).Set action by menu, can carry out various settings actions such as AF pattern, white balance, the setting of ISO photosensitivity and drive pattern setting.
Judged result at step # 19 is that menu switch does not have to judge whether release-push 21 is partly pressed, and promptly whether the 1R switch connects (#21) under the situation of connection.In judged result is under the situation of 1R switch connection, carries out the subroutine (#37) that is used to take the shooting action of preparing and taking.The back uses Fig. 6 to narrate the details of this subroutine.
Judged result at step # 21 is that the 1R switch does not have under the situation of connection, and #1 is identical with step, judges whether mains switch connects (#23).In judged result is under the situation of mains switch connection, returns step # 7, repeats aforementioned activities.On the other hand, under the situation that does not have to connect at mains switch, stop power supply and supply with (#25), return step # 3, become aforementioned resting state.
Then, use input action update time of Fig. 5 description of step #31.After entering this subroutine,, judge whether to have operated information setting knob 24 (#45) at first in order to import update time.In judged result is not have to return original routine under the situation of operation information setting knob 24.On the other hand, under the situation of having operated information setting knob 24, switch testing circuit 283 detects its direction of rotation (#47).
Then, judge whether detected direction of rotation is the direction (#49) that reduces update time.Be under the situation of the direction of rotation that reduces update time in judged result, whether arrive lower limit (#51) update time of judging last time.Lower limit can suitably be set, and for example can be set at about 0.1 second.In judged result is not arrive under the situation of lower limit, and step-length according to the rules begins sequentially to shorten update time (#53) from current set condition.
As shown in Figure 9, display refresh time in the photographing information on the LCD monitor 26 as update displayed 302 and overleaf.When having carried out rotary manipulation by information setting knob 24 toward the direction that shortens update time, if for example current set condition is initial value 30 seconds, then from the lower limit direction of Figure 10 (c) past (a), step-length in accordance with regulations reduces gradually.This step-length can be considered convenient the use and suitably decision.After update time, shortening was finished, return former routine.
In the judged result of step # 49 is not to reduce under the situation of direction, whether arrives higher limit (#55) update time of judging last time.Higher limit can suitably be set, and for example, the time degree as not being subjected to the dark current influence can be made as 9 minutes.In judged result is not arrive under the situation of higher limit, and step-length according to the rules prolongs update time (#57).When having carried out rotary manipulation toward the direction that prolongs update time, begin to increase gradually with predetermined step-length toward the higher limit direction of Figure 10 (e) from current state by information setting knob 24.After update time, prolongation was finished, return former routine.Be spaced apart an example this update time, but appropriate change.
Then, use the shooting among Fig. 6 description of step # 37 to move.This subroutine at first, is closed the photographing information (#61) that is presented on the back side LCD monitor 26 when the 1R switch connection.Then, the subroutine (#63) of excute phase difference AF control.This subroutine defocuses direction and defocus amount by what known phase difference AF detected photographic optical system 101, defocuses the drive controlling that direction and defocus amount are carried out lens driving mechanism 107 based on this, carries out the focusing of photographic optical system 101.
After phase difference AF finished, #9 was identical with step, judges whether to have set B door model (#65).In judged result is not set under the situation of B door model, carries out photometry/exposure computing, obtains exposure control values (#67) such as shutter speed or f-number.
On the other hand, the result of determination of step # 65 is to have set under the situation of B door model, and skips steps #67 enters step #69.This is because under the situation of B door model, as aforesaid, the switching time of shutter 213 is determined by photographer, does not need photometry and exposure computing.
Then, judge whether shutter release button 21 is pressed entirely, judge promptly whether the 2R switch connects (#69).In judged result is that the 2R switch does not have to judge whether the 1R switch connects (#89) under the situation of connection.In judged result is that the 1R switch does not have under the situation of connection, finishes to take action, returns former routine.On the other hand, be under the situation of 1R switch connection in judged result, return step # 69, become the holding state that alternately detects 1R switch and 2R switch.
