Next according to the flow chart of Fig. 3, illustrate that the observed information of camera 1 realization of present embodiment shows the flow process of handling.
<step S11〉system's initial setting
Be equipped with on the fuselage 20 of camera 1 and change camera lens 10 and day body unit 40, power supply is switched on.So the program that is stored in camera storage part 27 and the annex storage part 49 is forwarded to system controller 21 or annex controller 41, program start.Carry out the initial setting of system then.
<step S12〉the beginning live view
In camera 1, the photographed images that is generated by image pickup part 22 is shown on the display part 25, or is recorded in the card memory 26.Make a video recording continuously and show by the control of system controller 21, thereby show that on display surface 25A the live view image is the browse graph picture.The user looks like to confirm composition while observing browse graph, or determines to obtain the timing that is recorded in the photographed images in the card memory 26.
<step S13〉the selection pattern
In camera 1,, except common photograph mode or play mode etc., can also select a day bulk-mode as action.
For example ought select under the situation of common photograph mode, in step S14, carry out common camera work subprogram.And under the situation of having selected day bulk-mode, carry out action from step S15.
<step S15, S16〉detection accessory
System controller 21 detects whether day body unit 40 is installed as annex.(S16:Yes) carries out the work from S17 under the situation of installing, and not have (S16:No) under the situation of installation to repeat action from S13.
<step S17〉the selection celestial body
Can select the sun or the moon as celestial body in the camera 1.That is the positional information of database part 48 storage the Sun and the Moons.Under the situation of having selected the moon in the subprogram of S18 is handled the information of haunting of calculatings/the demonstrations moon, owing to calculating/demonstration processing of the information of haunting of itself and the sun described later is similar, thereby be not elaborated.And be not elaborated too for the processing of following subprogram.Under the situation of having selected the sun, carry out action from S19.
<step S19〉the acquisition master data
Selected the solar time, the 41A of information calculations portion obtains to be used to calculate the master data of the observed information of sunrise and sunset.That is, set positions portion 46 detection/setting observation places detect the time on date by clock 30 or radiowave timepiece 47, from database part 48 to the 41A of information calculations portion transmit the same day sun for example in the direction of haunting in Tokyo, go out to have no time and the data of correction coefficient.
<step S20〉judgement of sunrise/sunset
The 41A of information calculations portion judges it is the observed information that shows the observed information of sunrise or show sunset according to the moment of this moment.That is, under the situation in the moment before the sunrise that is in Tokyo constantly, handle the observed information that shows sunrise, under the situation in the moment after being in sunrise constantly, by observed information from the processes and displays sunset of S22 by the subprogram of S21.
<step S22〉calculate sunset constantly
The 41A of information calculations portion basis calculates the sunset moment T at observation position place from sunset moment T0 and correction coefficient A, the B in the Tokyo on the same day (east longitude 139.7 degree, north latitude 35.7 degree) that database part 48 obtains by known method.For example working as observation position is under the situation of east longitude λ, north latitude φ, calculates the sunset moment T in this place according to following approximate expression.
T=T0+A(139.7-λ)+B(35.7-φ)
For example A is 3.9, and B is 2.9.That is whenever advancing 1 to spend then sunset 3.9 minutes in advance constantly eastwards from the Tokyo longitude, latitude whenever advances 1 to spend then sunset 2.9 minutes in advance constantly northwards.
<step S23〉calculating sunset orientation
The 41A of information calculations portion with calculate sunset similarly constantly, according to obtain from database part 48 the same day Tokyo sunset orientation and correction coefficient, by the sunset orientation of known method calculating observation position.
<step S24〉the detection posture
The display surface 25A that posture detecting part 44 detects display part 25 is in flat-hand position or is in vertical posture.
<step S25, S26〉detection orientation/demonstration sunsetting
Shown in Fig. 4 (A), posture at the display surface 25A of the camera 1 that user OP is kept is approximate horizontal, be under the situation with the horizontal direction HD of gravity direction GD quadrature, display control unit 41B passes through arrow 25Y graphical display sunsetting on display surface 25A shown in Fig. 4 (B).
By above-mentioned display mode, the user can intuitively hold the sunsetting.In the example shown in Fig. 4 (B), arrow 25Y express user OP towards direction, be that the upper direction of display surface 25A is the direction that differs widely with the sunsetting.
And in the present invention, display surface 25A is that flat-hand position represents that user OP observes the state of display surface 25A easily from the top, is the state that is in the scope scope interior, that for example ± 30 spend that with respect to the horizontal plane is set angle.In like manner, vertical posture be meant be in respect to vertical in the scope of set angle, the state of the scope of degree for example ± 30.As long as be in above-mentioned scope, the user is visual confirmation display surface 25A easily just.
Display control unit 41B shown in Fig. 5 (A), at first calculates the imaginary line 25N of the north orientation of expression display surface 25A in order to show the sunsetting.Imaginary line 25N is according to being calculated by orientation detection portion 43 detected orientation this moment, and reflection in real time shows.And shown in Fig. 5 (B), serve as that the basis shows arrow 25Y with the azimuth angle theta A that represents the sunset orientation that the information calculations 41A of portion calculates.And be 0 degree this moment to the north of the azimuth angle theta A, to the west of be 90 degree.
And, when showing the sunsetting, preferred display navigation image not.Its reason is, is in when display surface under the situation of level, and browse graph similarly is the ground image of user underfooting, the visual confirmation that can hinder the user that the orientation is shown.Certainly also can exist expectation to take the demand of underfooting, therefore can carry out following control and come corresponding this situation, promptly, remove the demonstration of sunsetting by the operation of functional units such as shutter release switch 29, perhaps make the demonstration of sunsetting become translucent and with browse the doubling of the image and show.
<step S27〉show that sunset is constantly
When learned by the demonstration of S25 the user of sunsetting change direction of observation make the posture of display surface 25A of the camera 1 that keeps become roughly vertical shown in Fig. 6 (A), promptly roughly under the situation of gravity direction GD, display control unit 41B by with the co-operation of system controller, shown in Fig. 6 (B), carve TR (25T), sunset rhumb line SD at sunset and proofread and correct sunset overlapping being shown on the live view image of dynamical mean sun line 25S during TR constantly on display surface 25A, will proofreading and correct.And under the situation of the moon, also can use imaginary drawing picture with the monthly age corresponding shape.
Adopt above-mentioned display mode, the user both can correctly confirm the moment that is suitable for photographing with digital form, also can confirm the landscape that can make a video recording at this moment.
Wherein, correction sunset moment TR is meant the moment after the sunset moment T that the 41A of information calculations portion is calculated by the 41C of time correction portion that haunts has carried out proofreading and correct.That is, under the situation of the sun, sunset constantly T is exactly the moment that the elevation angle θ E of sun top is roughly 0 degree (0.9 degree), and under the situation of the moon, the elevation angle θ E that falls T constantly and be exactly moon center is roughly the moment of 0 degree.Yet for the user that purpose is to take scenery picture, comparing the sun and submerge fully moment under the horizontal line, more is for example to wish in that the moment of a few minutes photographs before.
Therefore in camera 1, haunt the 41C of time correction portion with sunset constantly T proofread and correct and be the correction sunset that can be from the observation place at least the integral body of the sun looked like to make a video recording TR constantly.At this moment, the 41C of time correction portion that haunts carries out with the angle of visual field ω of photographed images, promptly changing the corresponding correction of focal length F of camera lens 10.Promptly, shown in Fig. 7 (A), when changing under the situation that camera lens 10 is the bigger wide-angle lens of the angle of visual field ω of photographed images, want the Zao moment when proofreading and correct to the use of ratio shown in Fig. 6 (B) standard lens, shown in Fig. 7 (B), when changing under the situation that camera lens 10 be the less telephoto lens of the angle of visual field ω of photographed images, proofread and correct the moment late into than the use standard lens time.
The degree of the correction that the 41C of time correction portion that haunts is carried out, promptly constantly length or the amount of movement of imaginary drawing picture all can set by the user, and be under the situation of benchmark with angle of visual field ω for example, preferably use angle of visual field ω in 5~60% scope.As long as in above-mentioned scope, just can obtain the imaginary landscape of the desired nature of user.
And then, because camera 1 has the 41D of sky detection portion, thereby can also point out the observed information that is more suitable in photography.That is, in intermountain zone or metropolitan area, owing to blocked by the subject on the faces of land such as mountain range or building, it is different with the moment that with the horizontal line is benchmark that the sun is revealed in the aerial moment as the shooting object.In the camera 1, by the detected observed altitude of the 41D of sky detection portion, change dynamical mean sun overlappingly is shown in position on the live view image, promptly changes the correction sunset that calculated by the 41C of time correction portion that haunts TR constantly as 25S from the mountain range that observation position is watched.
For example shown in Figure 8, be in as mountain M under the situation of sunsetting, shown in Fig. 9 (A), the 41D of sky detection portion (1) judges whether the line SD top, sunsetting of photographed images exists the low low contrast portion of contrast.(2) judge whether the bottom of low contrast portion exists the border of light and shade then.(3) under the situation on the border that has light and shade, for example calculate and be parallel to horizontal sky boundary line in the position of 1/n in the center that from the angle of visual field is the image of ω.So the elevation angle theta X of this moment can calculate by following formula.
θX=(1/n)×ω
In camera 1, it is the correction sunset moment TR that benchmark calculates that the 41C of time correction portion that haunts further proofreaies and correct with horizontal line HL according to elevation angle theta X.Therefore, camera 1 also can be pointed out the observed information that is more suitable in photography in the intermountain zone etc.
<step S28〉the affirmation pattern
Under the situation that does not change pattern, the processing that camera 1 repeats from S24.And when having changed under the situation of pattern, by carry out the processing of selected pattern from the processing of S13.
As above illustrated, camera 1 is to show and the good camera head of operability as the relevant information of haunting of the Sun and the Moon of target celestial body by shirtsleeve operation.
And haunting of celestial body waits constantly also and can change owing to the height (absolute altitude) in observation place.In camera 1, can detect the height of observing the place by height detection portion 42 or set positions portion 46, thereby the 41A of information calculations portion can be undertaken and highly corresponding correction by known method.
In addition, in the above description, the situation that is fixed in fuselage 20 back sides with display part 25 is that example is illustrated, and also can be can be with respect to the display part of fuselage 20 rotations.In this case, the transducer that is equipped on the rotating part becomes the posture detecting part that the detection display surface is in flat-hand position or is in vertical posture.
In addition, in the above description, to the computational methods that the sun goes out to have no time and waits, the method that system loading is less and can handle at short notice has been described as the 41A of information calculations portion.Yet according to user's hope, for example as selection function, also can the higher known computational methods of service precision.
For example be under the situation of the sun, the position that celestial coordinate is fastened with 365.25 days around one week of ecliptic.Therefore at first calculate the equatorial coordinates value (right ascension α, declination β) corresponding with the moon sun according to the table of being stored or according to the calculating formula that is used to calculate the equatorial coordinates value.Use equatorial coordinates value (right ascension α, declination β), the longitude λ of observation place, latitude then
And the moment (local sidereal time) SG, thereby for example calculate elevation angle E and azimuth A by following known formula.By obtaining the condition that elevation angle E is 0 degree, calculate busy etc.
Elevation angle: sin (E)=sin (φ) * sin (β)+cos (φ) * cos (β) * cos (SG-α)
Azimuth: sin (A)=cos (β) * sin (SG-α)/cos (E)
In addition, the situation of the feature observation position of the calculating benchmark that wait as going out to have no time in use Tokyo has been described herein, also can in database part 48, have stored the information in a plurality of cities or place in advance, used the information in nearest place apart from the observation place.Can also use the information corresponding like that according to North America specification, European specification or Australian specification with user's main field of employment.Can also use by the information in the predetermined place of using of acquisitions such as Department of Communication Force 31.
In addition, it body unit 40 not only uses by detected position of GPS and 30 detected times on date of clock by set positions portion 46 and handles, and can also show the processing such as observation information of any time on date at the anywhere place of for example being selected by city name by configuration part, user use location 46.For example Figure 10 shows the display surface 25A of certain place one day every month sunsetting.
And the above camera 1 that the information of the Sun and the Moon is provided as celestial body that illustrated, also can be the camera that the information of the more sun of user's demand only is provided.In addition, as camera head, being not limited only to have the camera 1 of changing camera lens 10, for example can also be the compact camera that can't carry out lens changing, the mobile phone of being with camera or smart phone etc.The formation of above-mentioned camera head is more single.And then can also be all or part of the camera head that the inscape of day body unit 40 is set in fuselage 20.
Otherwise, camera of the present invention can also provide with as the relevant observed information of planets such as Venus, fixed star, artificial satellite or the comet of celestial body.The user for example can obtain these celestial body information by Department of Communication Force 31.
And to have narrated in the above description with celestial body be the example of main subject, and main subject also can be building or personage.
That is, the camera as the camera head of another execution mode has: shot object image is made a video recording and generated the image pickup part of photographed images; Display part with the display surface that shows above-mentioned photographed images; Detect the posture detecting part that above-mentioned display surface is in flat-hand position or is in vertical posture; And according to the testing result of above-mentioned posture detecting part, carry out when above-mentioned display surface is in above-mentioned flat-hand position and when being in above-mentioned vertical posture, show the display control unit of the control of different information on above-mentioned display surface, above-mentioned main subject is building or personage.
As display surface 25A is under the situation of flat-hand position, and it is the image of underfooting that browse graph looks like, thereby can be judged as the wish that the user does not photograph.Therefore information such as display orientation, moment or the number of photographing on display surface 25A.And work as display surface 25A is under the situation of vertical posture, shows photographic informations such as shutter speed or aperture.
In addition, be under the situation of flat-hand position as display surface 25A, also can show the user towards direction, be the building of the conduct master subject of display surface 25A when being vertical posture, the information of for example Tokyo Tower.
That is, the invention is not restricted to above-mentioned execution mode, can in the scope that does not change purport of the present invention, implement various changes, change etc.
