Embodiment
Below, according to accompanying drawing, use and used camera explanation preferred implementation of the present invention.Fig. 1 is the block diagram of the circuit of the camera 10 that relates to of expression one embodiment of the present invention.Camera 10 is digital cameras, is made of control part 1, image pickup part 2, the 2a of face detection section, image processing part 3, flash memory 4, image change extraction unit 5, record section 6, synthetic control part 7, display part 8, operating portion 9 etc.
The 2a of face detection section obtains view data from image processing part 3, whether comprises character facial in the process decision chart picture, detects its position and size etc. in situation about comprising.Image Change Detection section 5 has the temporary transient storage part of temporary transient storage usefulness, obtains view data from image processing part 3, temporarily stores this view data in predetermined timing, moves by it being compared to determine whether exist.Therefore, Image Change Detection section 5 performance is as the effect of such image comparing section: the image of relatively obtaining from above-mentioned image pickup part in a plurality of timings.
In addition, in image change extraction unit 5, be provided with the 5a of cycle detection section.In the situation that is dynamic image, and in the variation of this part with action, there are starting point and terminal point and repeat in the situation of this action the 5a of cycle detection section sense cycle.Can take out the periodogram picture that is equivalent to one-period by the 5a of cycle detection section.And, obtain periodogram as the time, according to the face location information in the picture that is detected by the 2a of face detection section, detect the periodogram picture in the place leave face location.And image change extraction unit 5 and the 5a of cycle detection section both can consist of with hardware, can be processed to realize by software by control part 1 again.
When having sent the photography indication by release-push, record section 6 records are obtained by image pickup part 2 and have been carried out the view data that compression is processed by image processing part 3.In addition, the dynamic image that is equivalent to one-period that temporarily is stored in the temporary transient storage part in the image change extraction unit 5 is recorded in record section 6 with rest image.In addition, the camera positions information of the photography date temporal information of never illustrated clock and watch section output, the never output such as illustrated GPS and view data associate and are recorded.These camera positions information and photography date temporal information can be utilized when image arrangement and image retrieval.Flash memory 4 is nonvolatile memories of can electricity rewriting, the program that storage is processed by image and control part 1 is carried out, the also various data such as storage adjustment data.And, so long as the memory of energy storage program etc. gets final product, can adopt the memory outside the flash memory.
The periodogram of the dynamic image that obtains in the lump when synthesizing the view data of the rest image of obtaining and be recorded in record section 6 when control part 7 will operate the release-pushes in the operating portion 9 and obtaining this rest image looks like to synthesize.The periodogram of dynamic image similarly is the image that is extracted by above-mentioned image change extraction unit 5 and the 5a of cycle detection section.The synthetic of rest image and periodogram picture is to carry out according to the face location information in the picture of being obtained by the 2a of face detection section.And synthetic control part 7 both can consist of by hardware, can be processed to realize by software by control part 1 again.
Then, use Fig. 2 illustrate rest image and dynamic image in the present embodiment photography and these images are synthetic after the reproduction of composograph show.Image when the image when Fig. 2 (a)～(c) is photography, Fig. 2 (d)～(f) are reproduction.
During photography, the cameraman is waiting for camera 10 that in order to photograph in the best timing of the expression of main subject 21 shutter regularly under the state of main subject 21.Among Fig. 2 (a) and Fig. 2 (b), the expression of main subject 21 is abundant not, and the expression of main subject 21 is fine among Fig. 2 (c), thereby the cameraman is recorded in record section 6 at this fixed cycle operator release-push with rest image.In addition, shown in Fig. 2 (a), (b), before the record rest image, begin to detect by pre-shooting (Pre-Capture) action cycle of the flag 23 that is in the background, the dynamic image that will be equivalent to one-period temporarily is stored in the temporary transient storage part in the image change extraction unit 5, and the dynamic image that will be equivalent to one-period when the record rest image is stored in record section 6.
When reproducing, the expression of main subject 21 is best is the captured rest image of timing at Fig. 2 (c), therefore reproduces to show this rest image.Yet, only be that the words of rest image can not be satisfied with appreciation.So, when the reproduction of present embodiment, show behind the dynamic image that is equivalent to one-period of the flag 23 of synthesis cycle motion.Namely, shown in Fig. 2 (d)～(f), main subject 21 is the captured rest images of timing at Fig. 2 (c), for the flag 23 that is in the background, then the synthetic dynamic image that is stored between Fig. 2 (a)～(c) repeatedly reproduces demonstration.
As above, in the reproduction of present embodiment, about face, show the result who captures the best smile of main subject 21 and take, for landscape, then periodically change in the dynamic image mode.And owing to caught cyclic variation, so Fig. 2 (d) and Fig. 2 (f) are identical image.Thereby repeat identical variation, can not feel to be discord even if stop somewhere reproducing yet.Although be the image of inactive basically, becoming a kind of can from the circulative dynamic image performance of any timing watching, be a kind of image with sensation time lapse.
Then, use the action of the camera 10 that flowchart text present embodiment shown in Figure 3 relates to.This flow chart and flow chart described later are to be carried out according to the program that is stored in flash memory 4 by control part 1.When starting when camera 10 power turn-ons, begin flow process shown in Figure 3.Once you begin, then at first whether to be the judgement (S1) of photograph mode.This camera 10 possesses photograph mode and reproduction mode, judges cameraman's model selection state by operating portion 9.
Whether the result of determination in step S1 is the judgement (S21) of reproduction mode then for being not in the situation of photograph mode.Result in this judgement neither return step S1 under the situation of reproduction mode.On the other hand, in the situation that is reproduction mode, then carry out the reproduction (S22) of photographs.In this step, from the photographs that is recorded in record section 6, select photographs and reproduce demonstration at display part 8 according to user's selection.When reproducing demonstration, record in the situation of cycle dynamic image having taken in the lump rest image and dynamic image (consecutive image), then use the demonstration of the composograph of Fig. 2 (d)～(f) explanation.The back will use Figure 10 to narrate the details of this reproduction mode.After finishing the reproduction of photographs, return step S1.
Result of determination in step S1 is to be in the situation of photograph mode, then whether has carried out the judgement (S2) of releasing operation.At this moment, whether operating portion 9 is supressed release-push fully and has been carried out the judgement of releasing operation.There is the repetitive operation of using Fig. 2 explanation in this result who judges as not carrying out in the situation of releasing operation, in step S11～S19, determining whether, exists in the situation of repetitive operation, obtain to be equivalent in the lump the dynamic image of this one-period.
Do not carrying out in the situation of releasing operation, at first beginning sequence photography (S11).The view data of the dynamic image (consecutive image) that will obtain this moment by image pickup part 2 temporarily is stored in the temporary transient storage part in the image change extraction unit 5.In addition, according to view data, show at display part 8 beginning live views.And, capacity as the temporary transient storage part that is used for temporarily storing, as long as greater than the capacity of the view data of setting as periodogram picture described later, when the view data of this temporary transient storage surpasses this capacity, from old view data, delete successively.
After in step S11, having begun sequence photography, then carry out face detection, AE (automatic exposure) and AF (auto-focus adjusting) (S12).In this step, according to the view data that is obtained by image pickup part 2, determine whether to have face by the 2a of face detection section, have in the situation of face its position of detection etc.In addition, obtain subject brightness according to view data, carry out the control of iso sensitivity etc. so that on display part 8, show with correct exposure; And the controlling value of computing shutter and aperture etc. makes it possible to the correct exposure recording image data.And then, carry out the focusing of phtographic lens so that the high fdrequency component of view data is in peak value.
After having carried out face detection, AE, AF, next whether change in the process decision chart picture part (S13).At this moment, by the dynamic image of the relatively more temporary transient storage of image change extraction unit 5, whether change in the part of judgement dynamic image.If this result who judges then returns step S1 as not changing.On the other hand, in situation about changing, judge whether this variation has left face (S14).The positional information of the face location information that is relatively determined by the 2a of face detection section at this moment, and the change section that detected by image change extraction unit 5 is judged.
Result of determination in step S14 is returned step S1 for not leave in the situation of face.This be because: face is that the possibility of main subject rather than background is higher.Also because: if there is change section near the face, it is synthetic then to be difficult to carry out image.On the other hand, in part the situation near face of the result who judges as variation, then carry out cycle spectral discrimination (S15).This moment as above-mentioned flag 23, the cycle of the action body by the variation of the 5a of cycle detection section determination cycles.The back will use Fig. 4 to Fig. 6 to narrate the details of this cycle spectral discrimination.
After the judgement of having carried out the periodogram picture, whether be the judgement (S16) of cycle background then.At this moment, according to the result of the cycle spectral discrimination among the step S15, whether be the judgement of carrying out periodically variable background image.As not being in the situation of cycle background, return step S1 in this result who judges.On the other hand, in the situation that is the cycle background, record period data (S17).In this step, the view data that is equivalent to one-period in the dynamic image (consecutive image) that will begin in step S11, that judge in step S15 temporarily is stored in the temporary transient storage part in the image change extraction unit 5 as the periodogram picture.
After in step S17, having carried out the record of cycle data, then whether there is the judgement (S 18) of previous image.Judge that as periodogram similarly be the no image that is recorded in the temporary transient storage part in the image change extraction unit 5 that has herein.Be not have to return step S1 in the situation of previous image in this result of determination.On the other hand, when having previous image, then remove this image (S19) in result of determination, return step S1.Because there is boundary in the memory capacity of periodogram picture, thereby deletes old view data.
Result of determination in step S2 is to have carried out in the situation of releasing operation, and (S3) then photographs.In photography, in step S12, control these elements according to exposure control values such as the shutter that calculates in advance and apertures, compress processing by the view data of the rest image obtained by image pickup part 2 image processing part 3 pairs of at this moment and wait image to process.And, in step S12, carrying out AE, AF, the exposure control value that obtain this moment and the focal position of phtographic lens can not changed in periodogram looks like to obtain.Therefore, as long as use expression to be in the mark of periodogram in looking like to obtain.After having carried out photography, next whether has the judgement (S4) of cycle data.Judge in step S17 the temporary transient storage part that whether cycle data temporarily is stored in the image change extraction unit 5 herein.
Result of determination in step S4 is to have in the situation of cycle data, then carries out composition and whether does not have vicissitudinous judgement (S5).Shown in Fig. 2 (a)～(c), judge whether main subject 21 any motion does not occur herein.Be in the situation about not changing in the composition in this result of determination, then photographs carried out the association (S6) of cycle data dynamic image.The view data of the rest image of obtaining in step S3 and the up-to-date cycle dynamic image of temporary transient storage in step S17 are associated herein.
When photographs and cycle data dynamic image are associated, perhaps the result of determination in step S4 or step S5 is in the no situation, to record (S7).Under the result of determination at step S4, S5 is no situation, only record the view data of rest image; And, in step S6, to have carried out in the situation of association of data, the view data of the dynamic image that will associate with the view data of rest image is recorded to record section 6 in the lump.
As above, in the present embodiment, for photograph mode the time, whether be the judgement of periodogram picture, in the situation that is the periodogram picture, then when taking rest image, also periodogram is looked like to associate the record section 6 that is recorded to.Then, when reproducing, shown in Fig. 2 (d)～(f), dynamic image is synthesized in rest image, main subject 21 shows with best expression, and background then shows with the image that moves.
Then, use Fig. 4 to the action of the cycle spectral discrimination of flowchart text step S15 shown in Figure 6.This periodogram as determination flow in, except using Fig. 2 background subject illustrated, that repeat same action (to be flag 23 in the example of Fig. 2 and Fig. 8, below be referred to as pattern A) outside, also judge from picture one end and move to the background subjects that disappear after the background subject (for example ship 25 shown in Figure 7 below is referred to as pattern B) of the other end and pyrotechnics as shown in Figure 9 27 occur like that (below be referred to as pattern C) in picture.
In the flow process of cycle spectral discrimination, the background subject of pattern A shown in Figure 8 (for example flag 23) is judged as no in step S101, determination cycles after step S201.In addition, the background subject of pattern B shown in Figure 7 (for example ship 25) is judged as in step S101 and is, and is judged as in step S105 and is, determination cycles after step S106.And then the background subject of pattern C shown in Figure 9 (for example pyrotechnics 27) is judged as in step S101 and is, in step S105, be judged as no, and after the step S301 determination cycles.
After entering into the flow process of periodogram picture shown in Figure 4, whether there is the judgement (S101) of nonmotile image.Judge the background subject that whether has motion in the picture by image change extraction unit 5 herein.This result who judges as the situation that has the background subject that as Fig. 2 and flag 23 shown in Figure 8, has motion under, begin most image with the predetermined timing such as last as temporary transient memory image IM01 with what be judged to be when motion, temporarily be stored in the interior temporary transient storage part (S201 of Fig. 5) of image change extraction unit 5.Next, the timing T01 with this moment is recorded in temporary transient storage part (S202).
If in step S201 and S202, stored image and timing, then next kept warning (S203) at display part 8.Owing to temporarily stored the candidate of periodogram picture, thereby kept warning so that the cameraman firmly maintains camera 10 during this.Then, judge after the temporary transient storage that has begun image, whether to have passed through 2 seconds (S204).Carry out the whether vicissitudinous judgement of tool (S211) of composition during this.Judge by image change extraction unit 5 whether the part except the motion parts that determines moves in step S101, and whether composition occurs changing herein.And, except image change extraction unit 5, can also setting example such as hand tremble test section etc., judge whether camera 10 mobile.
Do not change if the result of determination among the step S211 is composition, then return step S204.On the other hand, in the situation that the result who judges changes as composition, even if in fact may become the periodogram picture, but the cameraman has changed composition, or the figure action of subject and can't to carry out image synthetic, therefore can only be not with it as periodogram picture (S212), return former flow process.And, though whether in step S204, carried out judgement through 2 seconds, these 2 seconds only be for example expression.As described later, after 2 seconds, record temporary transient memory image IM02, this be because: this flag 23 may not carry out same action all the time very regularly, sometimes also can carry out irregular action, thereby need to consider the situation of the shape that can't turn back to the flag 23 identical with the temporary transient memory image IM01 that in step S201, obtains, the temporary transient memory image IM02 of preparation property ground record.Therefore from this viewpoint, also can suitably change 2 seconds among the step S204.
If the result of determination among the step S204 for passing through 2 seconds, then is recorded in temporary transient storage part (S205) with image at this moment as temporary transient memory image IM02, timing T02 at this moment is recorded in temporary transient storage part (S206).Then, according to the record of the temporary transient memory image IM01 among the step S201, whether passed through 10 seconds judgement (S207).Herein, 10 seconds only is for example expression, is not limited to this time.In the present embodiment, whether judgement has with the wind the periodically subject of action of such the carrying out of the flag 23 that swings in background, and as this background, and all being not suitable for of too fast or slow motion appreciated as rest image, consider this point, should suitably determine the time.
Result of determination in step S207 is just through in during 10 seconds, similarly carries out whether vicissitudinous judgement (S213) of composition with step S211.In this result who judges when not having composition to change, the then next whether judgement (S221) identical with temporary transient memory image IM01 except face.At this moment, the 5a of cycle detection section by image change extraction unit 5 carries out the whether consistent judgement of temporary transient memory image IM01 and present image.If judge whether the part that is judged to be change section by image change extraction unit 5 is identical, then can judge rapidly.And, with except the face, be that the countenance of main subject 21 can change sometimes because as Fig. 2 (a)～(c) is illustrated why.
Result of determination in step S221 causes loop cycle to become in the situation of identical image for the variation owing to the periodicity image, record timing T1 (S222) at this moment, record period image and cycle data T01～T1 (S223).Because being judged as in step S221 in the identical image is the timing of having recorded the image that is equivalent to one-period, thereby the recording image that regularly is equivalent to one-period among T01～T1 is in temporary transient storage part, and the timing of one-period also is recorded in temporary transient storage part.After recording these images etc., return former flow process.
Whether the result of determination in step S221 has passed through 4 seconds judgement (S225) for not exist in the situation of the image identical with temporary transient memory image IM01.As under not having through 4 seconds situation, return step S207 in this result who judges.On the other hand, as having passed through in 4 seconds the situation, whether be the judgement (S231) of the image identical with IM02 in the result who judges except face., about determining whether through 4 seconds, from having stored temporary transient memory image IM01, recorded temporary transient memory image IM02 after 2 seconds herein, and from the judgement the step S221 through judging as (namely 2 seconds+2 seconds) after equally spaced 4 seconds.
In the situation of result of determination in step S231 for image not identical with IM02 except face, the part that is considered as changing does not become periodically identical shape, thereby returns step S207.On the other hand, when the result who judges becomes periodically identical shape as the part that changes, then except face, become the image identical with IM02, therefore next record the timing T1 (S232) of this moment.Be judged to be in step S231 in the identical image is exactly the timing that record is equivalent to the image of one-period, therefore the recording image that is equivalent to one-period among general's timing T02～T1 is in temporary transient storage part, and also the timing with one-period also is recorded in temporary transient storage part.After having recorded these images etc., return former flow process.
Result of determination in step S207 is to have passed through in 10 seconds the situation, and perhaps the result of determination among the step S213 is considered as not being periodogram picture (S208) in the situation that composition occurs changes, and returns former flow process.For taking a decision as to whether the periodogram picture more than 10 seconds, if then can affect appreciation owing to the cycle is long, and cameraman can't change composition during this, so has unreasonable part on the method.Though be the periodogram picture, yet the cameraman also is difficult to lasting identical attitude, it is impossible that determination cycles can be considered to.But, fixedly in the situation of camera, also can wait for the longer time (more than 10 seconds) by tripod.This be because: in the situation about in composition, changing, can't obtain rest image in the present embodiment and the composograph of dynamic image (consecutive image).As having the such motion of flag 23, also can after step S201, temporarily store in the situation of periodogram picture, when next carrying out the judgement among the step S101, mark is set to enter into step S201.
Result of determination in the step S101 of Fig. 4 records nonmotile image (dynamic image) (S102) in the situation that does not have motion.Shown in Fig. 7 (a) and Fig. 9 (a), nonmotile image refers to not have the situation of the subject that moves in background.In these situations, as described later, taking dynamic image (consecutive image) afterwards, can in background, show the subject that moves, and in moment of execution in step S102, because this subject that moves is not present in the background, thereby the result of determination among the step S101 is yes.
If in step S102, recorded nonmotile image, then next record the timing T0 (S103) of nonmotile image.Then carry out the judgement (S104) of the direction of motion.As mentioned above, even if not motion when in step S102, processing, but in the example of Fig. 7 and Fig. 9, in background, show the subject that moves, therefore in step S104, come the motion of analysis background according to the view data that within 2～3 second time, obtained, judge the direction of motion by image change extraction unit 5.
After the judgement of having carried out the direction of motion, next carry out the direction of motion whether from the judgement (S105) of picture end to end.Fig. 7 is the example of pattern B, and in this example, ship 25 moves to right-hand member from the picture left end, so the result of determination among the step S105 is yes.On the other hand, Fig. 9 is the example of pattern C, and in this example, pyrotechnics 27 rises from bottom to top on the picture right side, and the result of determination among the step S105 is no.
Result of determination in step S105 is in the situation that is, then computing arrives the time (S106) of end, waits for through this time that calculates (S107)., as shown in Figure 7, go out in the picture end in the situation of spot 25, according to the action variation of this ship 25, computing arrives the required time of the other end from an end herein.This is in order to prevent that error detection is that the periodogram picture finishes when ship 25 disappears to people owner's subject 21 behind.Taked until the state of Fig. 7 (c) is provided with the design of non-sensitive band.And, be made as the short time of time outline that arrives the end of comparing this operation time.Then, determine whether through the time (S107) of institute's computing.Do not have as the time in the situation of process in this result who judges, similarly keep warning (S108) with step S203.After having carried out keeping warning, return step S107.
Result of determination in step S107 is through when arriving time till the end, next again determines whether not motion (S111).Because the time of the arrival end that calculates among the step S106 is shortened slightly, therefore in step S107, be judged to be the moment of time process, might ship 25 motions.So, in step S111, determine whether to have motion.And the judgement that whether has motion is undertaken by image change extraction unit 5.
Result of determination in step S111 is to have in the situation of motion, take a decision as to whether from subject that motion is arranged (being ship 25 herein) occur beginning 1 second～30 seconds (S121) during.Here, 1 second～30 seconds be the imagination traveling time of the subject (being ship 25 herein) that in the background of rest image, moves to another end from an end, be set as reproducing and can not feel dull appropriate time when appreciating.This time only is to illustrate for example, can suitably change in this purport scope.
Result of determination in step S121 is not in 1 second～30 seconds the situation of scope, to be considered as not being periodogram picture (S122), returns former flow process.On the other hand, be in the result who judges in 1 second to 30 seconds the situation of scope, similarly keep warning (S123) with step S108.Whether the judgement (S124) of composition variation then, is similarly arranged with step S5, S211, S213.This result who judges as the situation that has composition to change under, be considered as not being periodogram picture (S122), return former flow process.On the other hand, if there is not composition to change, then return step S111.
Result of determination in step S111 is in the situation of again not moving, and records this timing T1 (S112), and record period image and cycle data T0～T1 (S113).From the timing T0 that begins to record nonmotile image to again become nonmotile timing T1 during be exactly the subject of the backgrounds such as ship 25 moves to the other end from an end time.So be equivalent to the image of one-period among recording timing T0～T1, also record in the lump the timing of one-period.If recorded these images etc., then returned former flow process.As having the such motion of ship 25, also can after step S105, temporarily store in the situation of periodogram picture, when next carrying out the judgement among step S101 and the S105, mark is set to enter into step S106.
Result of determination in step S105 is that the direction of motion is not in the situation of picture end to end, and the possibility that belongs to pyrotechnics 27 shown in Figure 9 is higher.Therefore, after step S301 (Fig. 6), carry out the shooting of dynamic image (consecutive image), until there is not again motion.At first, carry out whether without the again judgement (S301) of motion.Judge that by image change extraction unit 5 state whether pyrotechnics 27 pass through Fig. 9 (b)～(d) disappears herein.
Result of determination in step S301 is in the situation that motion occurs, determine whether be during 10 seconds in (S311).During take a decision as to whether that the dynamic image that begins to record nonmotile image in step S102 rises herein, 10 seconds.As having passed through in 10 seconds the situation, be considered as not being periodogram picture (S312) in this result who judges, return former flow process.And in the present embodiment, the time of judging in step S311 is 10 seconds, yet is not limited to this, for the periodogram picture of pyrotechnics 27 grades, so long as the time of proper range get final product.
Result of determination in step S311 is in 10 seconds the time, similarly keeps warning (S313) with step S108, S123, S203.Then, determined whether similarly that with step S124, S213 composition changes (S314).When not having composition to change, then return step S301 in this result of determination.On the other hand, be to have in the situation of composition variation in result of determination, determine whether through 3 seconds (S315).Herein, determine whether from begin the step S102 to record without the dynamic image of moving image through 3 seconds.
Result of determination in step S315 for occur composition change be 3 seconds through before situation under change owing to produce composition, not too suitable for image is synthetic, thereby return former flow process.And the result who judges then jumps to step S302 as after having passed through 3 seconds.In this case, have and to carry out the synthetic possibility of image.Passed through 3 seconds if the moment of composition variation occurs, then can think the situation that pyrotechnics 27 is lighted, also can synthesize the record of dwelling period image in order to adopt this image even if composition changes.If the ship that in picture, passes through 25 on the way disappear fall can be very nature, yet in the such situation of pyrotechnics 27, also can be natural even if begin to be returned to the state of Fig. 9 (a) from the state of Fig. 9 (c), (d).So in the present embodiment, in the situation that has composition to change, if from the dynamic image (sequence photography) that begins to record nonmotile image, passed through 3 seconds, namely can be used as periodogram and look like to process.
Result of determination in step S301 is in the situation about not moving, and perhaps passed through in step S315 in 3 seconds the situation, records this timing T1 (S302), and record period image and cycle data T01～T1 (S303).From beginning to record nonmotile image the step S102, in the moment that motion disappears again, record is equivalent to the image of one-period.So, will be equivalent to the temporary transient storage part of recording image in image change extraction unit 5 of one-period among timing T01～T1, also record in the lump the timing of one-period.Return former flow process after having recorded these images etc.
As above, in the sub-process of cycle spectral discrimination in the present embodiment, for flag 23 (pattern A) like that picture than close limit in the background subject, ship 25 (pattern B) of repetitive operation move to the like that background subject that a bit manifests and disappear at other points in picture of the background subject of the other end and pyrotechnics 27 (pattern C) from picture one end like that, judge that each since the cycle of origin-to-destination, looks like to come record with the image during this as periodogram.And, in the present embodiment, it is whole to have recorded view data during the record period image, and because personage's part (main subject 21), because the possibility of motion is higher in during this period, therefore also can in the scenes such as flag 23 and pyrotechnics 27, only record the image of the change section of synthetic usefulness.
Then, use the reproduction of the captured periodogram picture of camera in the flowchart text present embodiment shown in Figure 10 10.The flow process of this reproduction mode is to carry out in the step S22 of Fig. 3.In the reproduction mode of step S22, also reproduce the common rest image that does not have the synthesis cycle image, and in Figure 10, illustrate that the reproduction of the composograph that has synthesized the periodogram picture in rest image shows.
After entering the flow process of reproduction mode, at first carry out the selection (S401) of reproduced image.Herein, with the reproduction of common rest image similarly, operating portion 9 operated and select among the photographs that thumbnail shows from having carried out by the user.After having carried out the selection of reproduced image, the image of compare cycle data T0～T1 (S402) next., read regularly the dynamic image (consecutive image) of T0～T1 during this from record section 6 herein, the view data of relatively reading, thus determine whether and have motion parts.
Next, the part with motion (S403) of judgement except face.Judge that the part have motion as above-mentioned flag 23, ship 25, pyrotechnics 27 is positioned at the position where of picture herein.For example example shown in Figure 11 is the consecutive image of having taken main subject 21 take pyrotechnics 27 as background, and Figure 11 (d) is rest image.In step S403, by comparing Figure 11 (a)～(d), pyrotechnics 27 is to have the part of motion except face thereby determine.And if detected face by the 2a of face detection section, and photography the time recorded face location, also can use this information.
If in step S403, determine the part with motion, then next divide face and have boundary (S404) between the part of motion.In example shown in Figure 11, between the face location of main subject 21 and pyrotechnics 27, determine boundary line 29.This boundary line 29 is straight line in example shown in Figure 11, and different according to the shape of the background subject of subject and motion, also can be curve.
Determined boundary in step S404 after, next, with respect to face, dynamic image (S405) is adopted in the boundary outside.Herein, with respect to face, the dynamic image (consecutive image) of taking during adopting from timing T0 to T1 to the image in 29 outsides, boundary line.Then, with respect to face, the inboard rest image (S406) that adopts of boundary.With respect to face, the image of 29 inboards, boundary line is adopted the rest image (corresponding with Figure 11 (d)) of in step S3, taking herein.
Then, dynamic image and the rest image that adopts synthesized and shows (S407).Herein, 29 are the boundary take the boundary line, and it is synthetic that the dynamic image (consecutive image) that adopts in step S405 and the rest image that adopts in step S406 are carried out image, shows at display part 8.Repeatedly show Figure 11 (a)～Figure 11 (d) until indicated end of reproduction to show.Therefore, main subject 21 is taken with rest image and shows, and shows the image with motion of pyrotechnics 27 till occur disappearing in background.And, in the present embodiment, as shown in figure 11, between the background subject of face and movement, get the boundary line and come synthesized still image and dynamic image, yet also can cut image along the profile of rest image or dynamic image, carry out image and synthesize.
And, in an embodiment of the invention, taking the advance record of Mobile state image (consecutive image) of rest image, can certainly after taking rest image, record dynamic image, perhaps at the forward and backward record dynamic image of taking rest image.
Then, use Figure 12 and Figure 13 that the variation of one embodiment of the present invention is described.In an embodiment of the invention, the cycle of carrying out when taking rest image is judged, also records in the lump the dynamic image (consecutive image) that is equivalent to one-period.In this variation, if the cameraman has touched the part of wishing to be recorded as the periodogram picture before taking rest image, then take a decision as to whether cyclic variation, carrying out in the periodically variable situation the pre-recorded dynamic image that is equivalent to one-period.
Figure 12 is the figure of situation of the periodogram picture of pre-recorded variation of expression.The cameraman touches the part of wishing that the cycle of carrying out is judged from live view is shown in subject landscape 31 on the display part 8 of camera 10.In the example of Figure 12, if touched flag 23, the touch panel (not shown) that then is disposed at display part 8 front surfaces can detect touch location, by the 5a of the cycle detection section sense cycle of image change extraction unit 5.If detect the cycle this moment, then show that in the cycle of display part 8 8a shows, and according to the cycle that detects, the dynamic image of recording section image 33 (consecutive image).
The action of this variation then, is described as check process according to periodogram shown in Figure 13.Align in the situation of carrying out periodically variable part record period image in hope, the cameraman can touch this part, therefore, at first carries out judgement and the record (S501) of the image of specifying part., judge that by touch panel which position is touched herein, and determining in the situation about being touched, record view data at this moment.
