The main flow of interval photography
As shown in Figure 3, when photographing at interval, at first processing flag (S1) is being synthesized in cancellation, and the synthetic time counter of shot object image is carried out initialization, and count value is made as 0 (S2).At this, synthesizing and handling flag for judging whether with the bright relatively more synthetic processing of the view data implementation that is equivalent to a shot object image.Then, photography time interval, the interval t1 that the user is set carries out timing (S3), in order to photograph every time interval t1.
Namely carry out single exposure every photography time interval t1 and handle (S4), then confirm whether to be provided with is synthesizing and handle flag (S5).When synthesizing when handling flag and being cancelled, processor 104 is obtained the view data (S6) that is equivalent to a shot object image from CCD (imaging apparatus) 101.Synthesize when handling flag and be provided with, then relatively synthesize processing owing to becoming clear, thereby before this bright relatively more synthetic processing finishes, forbid obtaining view data.
Then, processor 104 judges whether the user sets needs and preserve at regular intervals the obtained view data (S7) of t1 at interval, need to preserve view data if the user sets, carry out then at regular intervals that the output of the shot object image view data of output is at interval handled (output of partition image file is handled) (S8) and this view data is saved in as SD card or the preservation in the built-in memory 120 of medium and handle.And if the user does not have above-mentioned setting, the processing of then skipping S8 directly moves to the processing of S9.
In S9, set synthesizing and handle flag.Then, processor 104 moves to bright relatively more synthetic treatment S 10.Will be at following detailed description about bright relatively more synthetic processing.
The bright relatively more synthetic preprocessor 104 of handling is judged that users have or not and is carried out the end operation (S11) of photographing at interval.
If the user has carried out the end operation of photographing at interval, then processor 104 finishes photograph processing at interval, if and the user does not carry out the end operation of photographing at interval, then processor 104 judges whether photography time interval t1 has crossed (S12) at interval, if photography time interval t1 passes through at interval, then move to S3, carry out the processing of S3 to S12.
Below with reference to the bright relatively more synthetic flow process of handling of description of drawings.
Bright relatively more synthetic example substantially
Fig. 4 is the bright relatively flow chart of synthetic basic example in the flow process shown in Figure 3.
At first, processor 104 judges whether the count value of synthetic time counter is 0 (S101).
If the count value of synthetic counter is 0, then processor 104 with update image with the view data of storage area β as a comparison object image data be the initial value of composograph data, copy among the composograph usefulness storage area α (S102).
If the count value of synthetic time counter is not 0, then processor 104 is carried out bright relatively synthetic the processing to each pixel, namely obtaining section obtain at interval with certain hour upgrade with view data during in, each pixel is carried out renewal that this obtaining section obtains with the current renewal in the view data with the luminance ratio between view data and the composograph data, and the data (S103) of the briliancy of preserving in the pixel of data replacement composograph with storage area α with the bigger side's of briliancy briliancy.
Then, after the count value of synthetic time counter added 1 (S104), processor 104 is synthesizing in cancellation handled flag (S105), finishes bright relatively synthetic the processing, moves to S11 shown in Figure 3.
According to above-mentioned a series of processing, accept the view data that is equivalent to an image of the shot object image that the light by photographic lens obtains obtaining imaging apparatus (CCD) with specified period, carry out view data obtain control during in, each pixel is carried out luminance ratio, make up composograph.The user can obtain composograph immediately for this reason, and after will digital camera not taking home again to the relatively more synthetic processing that become clear of a series of shot object images of obtaining, thereby made things convenient for the user.
And then, also the view data of the shot object image obtained at interval with certain hour can be saved in the recording medium in the above-mentioned basic example, also digital camera can be taken home with personal computer for this reason and compensate these view data.
The bright relatively more synthetic embodiment 1 that handles
Fig. 5 is the flow chart of the bright relatively more synthetic embodiment 1 that handles shown in Figure 3.
At first identical with basic example, processor 104 judges whether the count value of synthetic time counter is 0 (S101).
Then, if the count value of synthetic counter is 0, then processor 104 with update image with the view data of storage area β as a comparison object image data be composograph data initial values, copy among the composograph usefulness storage area α (S102).
If the count value of synthetic time counter is not 0, then move to S106, processor 104 is respectively θ 1 He with the composograph that the composograph data among the storage area α constitute at the horizontal corner of lateral rotation direction and the Angle of Trim of fore-and-aft tilt direction to be kept at composograph
And the update image current that obtain, that be kept at shot object image that obtains in the control with at interval view data at regular intervals is respectively θ 2 ands with image at the horizontal corner of lateral rotation direction and the Angle of Trim of fore-and-aft tilt direction with the renewal among the storage area β
The angle of inclination of the composograph that judgement constitutes with the composograph data and the current renewal that obtains with the absolute value of the difference between the angle of inclination of image whether less than the threshold values of stipulating.
Specifically in embodiment 1, if the count value of synthetic time counter is not 0, then processor 104 is further judged difference between horizontal rotational angle theta 1 and the θ 2 whether in θ th (for example 1 °), and the judgement Angle of Trim
With
Between difference whether exist
In (for example 1 °).When the difference between horizontal rotational angle theta 1 and the θ 2 with in θ th (for example 1 °), and Angle of Trim
With
Between difference exist
In the time of in (for example 1 °), the renewal that processor 104 will be exported at regular intervals is saved in view data with the current renewal in the view data to be upgraded with among the image memory region β, and each pixel is in correspondence with each other carried out bright relatively synthesizing handle, more current renewal is with the briliancy of view data and the briliancy of composograph data, carries out replacement Treatment (S107) with the bigger side's of briliancy briliancy data at composograph in storage area α.The later processing of S104 is identical with basic example.
On the contrary, if the absolute value of the difference between the angle of inclination of the composograph that constitutes with the composograph data and the current renewal usefulness angle of inclination of obtaining of image is greater than prescribed threshold, then skip the processing of S107 and directly move to the processing of S105, namely the absolute value of the difference at angle of inclination is at θ
ThMore than or
More than, then not carrying out bright relatively synthetic the processing, the return span photography is mobilely used the replacement Treatment that the renewal that next time obtains is carried out with view data.
According to above-described embodiment 1, in the time of can in photographing at interval, making 1 run-off the straight of digital camera main frame for a certain reason, avoid being in the image of obtaining when tilting relatively synthetic processing of become clear with this digital camera main frame 1, make the factitious problem of composograph thereby solution night photography culminant star optical track mark etc. depart from.
In other words, in above-described embodiment 1, image processing part changes the replacement Treatment content according to the testing result of posture change test section, and the posture change of flexible corresponding camera head main frame makes up good composograph.
The bright relatively more synthetic embodiment 2 that handles
Fig. 6 is the flow chart of the bright relatively more synthetic embodiment 2 that handles shown in Figure 3.
At first identical with basic example, processor 104 judges whether the count value of synthetic time counter is 0 (S101).
Then, if the count value of synthetic counter is 0, then processor 104 with update image with the view data of storage area β as a comparison object image data be composograph data initial values, copy among the composograph usefulness storage area α (S102).
If the count value of synthetic time counter is not 0, and is then identical with embodiment 1, move to S106, the horizontal rotational angle theta 1 of processor 104 usefulness lateral rotation directions and the Angle of Trim of θ 2 and fore-and-aft tilt direction
With
Judge that whether difference between horizontal rotational angle theta 1 and the θ 2 is at θ
Th(for example 1 °) is with interior and Angle of Trim
With
Between difference whether exist
In (for example 1 °).If judged result is "Yes", then with the embodiment 1 identical S107 that moves to, carry out bright relatively synthetic the processing.
To this,, that is to say that the absolute value of difference is θ if judged result is "No"
ThMore than or
More than, then processor 104 moves to S102, and update image is copied to composograph with among the storage area α with the view data among the storage area β, and the processing later with embodiment 1 identical implementation S104.
It is processor 104 plays image processing part in embodiment 2 effect, when the absolute value of the difference between the angle of inclination of the angle of inclination of the image that constitutes with view data with the current renewal that obtains and the image of composograph data formation during less than prescribed threshold, carry out replacement Treatment at composograph in storage area α with view data with the current renewal that obtains, and when the absolute value of the difference between the angle of inclination greater than prescribed threshold the time, with the current renewal that obtains with view data object image data as a comparison, be saved in composograph with among the storage area α, then move to the replacement Treatment of carrying out with view data with the renewal that obtains next time.
According to above-described embodiment 2, can be at digital camera main frame 1 for a certain reason and during run-off the straight,
The view data that obtains during with inclination is restarted bright relatively synthetic the processing, for this reason, even continue under the situation of run-off the straight at digital camera main frame 1, also can continue to carry out bright relatively synthetic processing of photography at interval, improve the serviceability of the digital camera of embodiment 1.
The bright relatively more synthetic embodiment 3 that handles
Fig. 7 is the flow chart of the bright relatively more synthetic embodiment 3 that handles shown in Figure 3.
At first identical with basic example, processor 104 judges whether the count value of synthetic time counter is 0 (S101).
Then, if the count value of synthetic counter is 0, then processor 104 with update image with the view data of storage area β as a comparison object image data be composograph data initial values, copy among the composograph usefulness storage area α (S102).
If the count value of synthetic time counter is not 0, and is then identical with embodiment 1, move to S108, processor 104 is at first used the Angle of Trim of fore-and-aft tilt direction
With
Judge Angle of Trim
With
Between difference whether exist
In (for example 1 °).
If judged result is "Yes", then processor 104 moves to S109, with horizontal rotational angle theta 1 and the θ 2 of lateral rotation direction, judges that whether difference between horizontal rotational angle theta 1 and the θ 2 is at θ
ThIn (for example 1 °).
If the judged result among the S109 is "Yes", then processor 104 is identical with embodiment 1, transfers to S107 relatively synthetic processing of becoming clear.
And if the judged result among the S109 is "No", then judge the user have or not setting will with upgrade that the view data that tilts with view data still keeping of constituting is saved in as image file that preservation in the recording medium is handled and before whether the angle of inclination surpasses the valve judgment value preservation of synthetic composograph data handle (S110).
If judged result is "Yes" in S110, then will output to (S111) in the recording medium as image file to upgrade the view data that still keeps tilting that constitutes with view data, then, implementation is rotated and is handled compensation, is that the difference at angle of inclination is rotated renewal image (S112) with the size.And if the judged result among the S110 is "No", then skip the processing of S111, compensation is handled in the rotation that moves to S112.
Processor 104 plays the effect of image processing part in embodiment 3, when with the absolute value of the difference between the angle of inclination of the angle of inclination of the current image of obtaining that relatively constitutes with briliancy data and the image of composograph data formation during less than prescribed threshold, carry out replacement Treatment at composograph in storage area α with view data with the current renewal that obtains, and when the absolute value of the difference between the angle of inclination greater than prescribed threshold the time, then carrying out rotation compensation handles, difference with the angle of inclination of image is rotational angle, rotate the image that the current renewal that obtains constitutes with view data, reduce poor between the angle of inclination of image, then carry out replacement Treatment.
In addition, in the horizontal rotational angle theta with the lateral rotation direction
