Embodiment
Below, the preferred implementation of having used camera of the present invention is used in explanation with reference to the accompanying drawings.The camera 10 of the 1st execution mode of the present invention is a digital camera, takes still image and recording image data in recording medium.And, during reproduction, the part that can extract the brightness variation in the still image is that the center generates the luminous point enlarged image as candidate portion with this candidate portion, synthesize with captured original still image, show the composograph that moves in the mobile mode of luminous point and reproduce.Thus, get used to the camera user of photo photography in the past and can take with employed simple operations all the time, and, can access the image that also is suitable for be connected the content when appreciating with external equipment such as television set.
Before the structure of the camera 10 that present embodiment is described, use Fig. 2 and Fig. 3 that the consideration method of the reconstruction of image in the camera 10 that image-reproducing means of the present invention has been installed is described.
In nearest cameras such as digital camera, can on display part such as the built-in liquid crystal of camera or organic EL or exterior display devices such as television set that connects via efferent and personal computer, show photography simply before and photograph after image.
And, in nearest cameras such as digital camera, also can carry out dynamic image photography etc. simply.But common people are difficult to shoot according to the mode of dynamic image can allow the works of the degree that other people watch.Relative therewith, still image have the shooting of making moment worksization effect, so, promptly finish the work outside not needing to take in the moment of taking.
But as shown in Figure 3, under the situation of utilizing reproduction display images such as big frame TV machine, the image without any variation is dull and the people is bored fully, so preferred image has some variations.For example, under the situation of the landscape of the grandness that has huge luminance difference shown in Figure 2 etc., can attempt changing glittering of the sunlight that shines on the cloud 30 etc., make luminous component in time through and move.That is,, can ferment the atmosphere of grand landscape when so that the mode that the 32a of luminous point portion that glitters, 32b, 32c move along the edge 31 of cloud 30 is reproduced when showing.Because the motion of cloud and the angle of the sun etc. are at every moment changing, so, unexpected even repeated multiple times adds in luminous in a flash variation, also not sense naturally especially.
In the present embodiment, according to the still image shown in Fig. 4 (a), the brightness change section that the brightness of edge 31 grades of detection cloud 30 changes, the candidate portion of selecting from this brightness change section is carried out the luminous point processing and amplifying, order according to Fig. 2 (a) → (b) → (c) makes the luminous point flicker successively, thus, the image that glitters and moving of playback light.
Like this, though be still image and the image that does not have big especially variation, but, when continuing to be presented on the picture of television set 20 grades (with reference to Fig. 3), synthetic demonstration makes the candidate portion image that brightness brightens (luminous point) and this luminous point moves on every side in the brightness change section, thus, the reproduction that can directly mirror landscape outside window.
According to this consideration method, in the image-reproducing means of present embodiment,, as shown in Figure 2, can natural mode carry out the synthetic and demonstration of image with the variation of optical scintillation at the still image of constantly finishing in photography.In addition, also can with photography simultaneously, utilize sound such as collection line record chirping of birds in advance, reproduce repeatedly reproducing when showing.
Then, the above-mentioned structure that can reproduce the camera of display image is described.Fig. 1 is the block diagram of electrical structure that the camera 10 of the 1st execution mode is shown.Camera 10 has: control part 1, photography portion 2, photoflash lamp 2a, recording portion 3, the compression preservation 3b of portion, candidate extraction portion 4, mobile control division 5a, the peripheral light amount increase 5b of portion, collection line 6, synthetic control part 7, efferent 8, liquid crystal display part 8a and operating portion 9.
Collection line 6 is converted to the signal of telecommunication by microphone etc. with sound, and output sound signal.Recording portion 3 is according to the control signal from control part 1, and record is from the still image of photography portion 2 outputs, the view data of dynamic image.And,, also carry out from the record of the voice data of collection line 6 outputs with record image data.And, output is write down according to control signal view data and voice data.
In the view data of the still image of candidate extraction portion 4 from be recorded in recording portion 3, extract and given the part of contrast with high light as candidate portion.In the present embodiment, there is the striking contrast degree, dazzles the eyes the landscape of the luminous part in ground to give glittering of light, thus, reproduce image still image is additional after changing at direct sunlight etc.At this landscape image, candidate extraction portion 4 selections have the part of the variation of light.
For example in the example of Fig. 2, candidate extraction portion 4 is extracted candidate portion from the edge 31 of cloud 30.That is, the edge 31 of cloud 30 is the line segments along the edge of cloud, and the part in candidate extraction portion 4 these edges 31 of extraction is as candidate portion.In addition, image is not limited to landscape image, the also character image that can be shined upon, and under this situation, candidate extraction portion 4 is extracted the cheek part that is shone, and as described later, can reproduce sparkling scene.
The peripheral light amount increase 5b of portion improves the image processing of the surrounding brightness of the candidate portion that is extracted by candidate extraction portion 4.That is, the 5b of peripheral light amount increase portion generate candidate portion around glittering and become bright image suddenly as the synthetic image of using.As the bright composograph of unexpected change, show by the area that enlarges luminous component and to glitter.About the expansion of this area, can carry out the expansion of candidate portion is various areas expansions such as star-like, cross for circular or expansion.And the peripheral light amount increase 5b of portion returns to original light quantity once more after becoming bright image processing suddenly.
Synthetic control part 7 is at the original still image that is recorded in the recording portion 3, increase peripheral light amount by the peripheral light amount increase 5b of portion, by mobile control division 5a original still image is synthesized with image with passing through synthesizing of moving in time, generate the image shown in Fig. 2 (a)～(c).That is, by peripheral light amount increase 5b of portion and mobile control division 5a, generate successively light quantity increase portion in time through and the synthetic image of use that moves, so, synthesize control part 7 with a plurality of syntheticly synthesizing that these generate successively with image and original still image.
The compression preservation 3b of portion compresses preservation to the view data that is write down by recording portion 3, and, synthetic view data in synthetic control part 7 is compressed, and it is preserved.
Liquid crystal display part 8a is arranged on the camera 10, reproduces the document image of displayed record portion 3, and displaying live view shows shot object image before photography.And the composograph that synthetic control part 7 is generated reproduces demonstration.And, use the preceding view data of photography from photography portion 2, synthesize processing by synthetic control part 7, show the image that luminous point portion moves.Show the image when having carried out synthetic the processing before photographing, thus, can enjoy the enjoyment of photography.
Then, use Fig. 4 that the synthetic processing of image of present embodiment is described.Fig. 4 (a) illustrates an example of captured landscape.In this illustrative landscape, the edge of cloud 30 31 is because sunlight and luminous brightly.When getting lightness distribution along the horizontal line 35a along X-direction, the Luminance Distribution of the image shown in this Fig. 4 (a) is shown in Fig. 4 (b).As shown in the figure, the part that the sun reflection of light of the end 31 of cloud 30 is strong is bright especially, and the part adjacent with this end 31 is so not bright.
In the present embodiment, from the end 31 of this cloud 30, select candidate portion, bright the emphasizing that become on every side of this candidate portion handled.Promptly, shown in Fig. 4 (b), from than selecting candidate portion the bright part of regulation brightness B, at the scope 33a(that comprises this candidate portion by the part of dotted line), shown in the arrow among Fig. 4 (b), make its brightness brighter than the end 31 of cloud 30 on every side.After carrying out this processing, shown in Fig. 4 (c), become local image that glitter brightly, that have luminous point 32a.
And, shown in Fig. 4 (d), get Luminance Distribution along horizontal line 35b along X-axis, from the part that becomes clear than regulation brightness B, select candidate portion, at the scope 33b(that comprises this candidate portion by the part of dotted line), shown in the arrow among Fig. 4 (e), make its brightness brighter than the end 31 of cloud 30 on every side.After carrying out this processing, shown in Fig. 4 (f), become local image that glitter brightly, that have luminous point 32b.
In addition, when the A on every side that makes candidate portion becomes bright, shown in Fig. 4 (b), (e), carry out image processing at scope 33a, 33b and make it become certain brightness, in other words, at the brightness peak of original image, generate bright more part, increase its area.
Like this, even identical image as Fig. 4 (a) with (d), by the judgement position (switching of horizontal line 35a, 35b) of change Luminance Distribution, stipulates that thus the above part of brightness B changes.Therefore, change the position of candidate portion successively, thus, the change in location of luminous point 32a, 32b can have the image appearance of the sense of glittering.
In addition, in Fig. 4 (c), (f), handling in the circle scope of candidate portion periphery with luminous point 32a, 32b, but be not limited thereto, for example as shown in Figure 5, also can be star-like or other shapes.Emphasize shape partly by change, can be to give the sense of glittering with round different atmosphere.About this change of shape of emphasizing part, the data and the switching successively of the pattern of part emphasized in storage in the peripheral light amount increase 5b of portion, perhaps also can switch according to user's selection.
Use flow chart shown in Figure 6, illustrate that being used to carry out this luminous point that light is emphasized emphasizes the action that shows.Control part 1 is cooperated and is carried out this flow process with candidate extraction portion 4, the peripheral light amount increase 5b of portion, mobile control division 5a etc. according to the view data that is recorded in the recording portion 3.
After entering luminous point and emphasizing flow process, at first, variable Y is set 0(S101).Then, this variable Y is added Δ Y(S102), judge whether this variable Y equals the boundary value Y1(S103 of Y).Result of determination at step S103 is that variable Y does not arrive under the situation of boundary value Y1, then, variable X is set 0(S104), this variable X is added Δ X(S105), judge whether this variable X equals the boundary value X1(S106 of X).
These steps S101～S103 is following steps: when setting the X shown in Fig. 4 (a), Y-axis, till the boundary value Y1 of Y-axis, at interval successively change zone that brightness judge with Δ Y along Y-axis.And step S104～S106 is following steps: change the X coordinate, and meanwhile the brightness determinating area in the picture changed, till the boundary value X1 that arrives X-axis.Here, owing to when carrying out brightness and judge according to continuous pixel, judge that object pixels is meticulous too much again, therefore, it can be the pixel separation of 50 parts of left and right sides degree with picture segmentation that Δ Y and Δ X are set at.
Result of determination at step S106 is that variable X does not arrive under the situation of boundary value X1, and then, (X, whether the brightness of Y) locating is than regulation brightness B1 bright (S107) to judge coordinate.In this result of determination is under the situation about becoming clear unlike regulation brightness B1, returns step S105, and the X coordinate is added Δ X, judges at next coordinate place whether brightness is brighter than B1.
Result of determination at step S107 is that (X under the situation that the brightness ratio B1 that Y) locates becomes clear, judges the brightness (S111) of A portion on every side to coordinate.Here, A portion is equivalent to the zone of star-like mark of circles mark, Fig. 5 of Fig. 4 (c), (f) on every side.Then, judge whether the interior whole pixels in zone of A portion are brightness B1 above (S112) on every side.This result of determination for around the brightness of whole pixels in the A portion be under the situation more than the B1, return step S105.
On the other hand, the result of determination of step S112 for be not whole pixels under the situation more than the brightness B1, as candidate portion, extract and write down this coordinate (X, Y) (S113).Undertaken these by candidate extraction portion 4 and extract operation.Here, under brightness is situation more than the B1, return step S105 and be because around under the bright situation of whole pixels of A portion inside,, thereby from candidate portion, get rid of even the part of circles mark, star-like mark is bright also not obvious.On the other hand, under some dark situation only, become bright, can show obviously and glitter by the part that makes circles mark, star-like mark.
In step S112 with the Y("Yes") break away from circulation or in S113, write down coordinate (X, Y) after, return step S105, judge laterally carrying out brightness at interval, till the X coordinate arrives boundary value X1 with Δ X.By carrying out these a series of processing, finish along judging in the delegation of X-axis, record brightness be the above but whole coordinates part (candidate portion) darker around it of B1 than B1 (X, Y).
In step S106, when the X coordinate arrives boundary value X1, enter step S102, Y coordinate place after variable Y is added Δ Y Yi Bian change the X coordinate, becomes clear and the part (candidate portion) darker than B1 around it Yi Bian detect than regulation brightness B1, write down this coordinate (X, Y).
Judge when above-mentioned brightness and to arrive the other end along Y direction from an end and when finishing, in the judgement of step S103, variable Y becomes boundary value Y1.By carrying out these a series of processing, the judgement of whole image finishes, record brightness be the above but whole coordinates part (candidate portion) darker around it of B1 than B1 (X, Y).
After variable Y becomes boundary value Y1, then, judge that whether candidate's number is less than 5(S115).In this step, whether the quantity of judging the candidate portion that writes down in step S113 is less than stated number (being " 5 " here).In addition, this stated number is not limited to 5, so long as get final product in the suitable quantity of the degree of carrying out telling on when luminous point is emphasized to show.
Be less than for candidate's number in the result of determination of step S115 under 5 the situation, amplify determinating area (S116).That is, when the quantity of candidate portion after a little while, emphasize the DeGrain that shows, so, enlarge in step S111, carry out around the scope of A portion.This is because by the scope of A portion around enlarging, being judged to be in step S112 all be possibility raising more than the B1, the quantity increase of candidate portion.In addition, under the too much situation of the quantity of candidate portion, on the contrary, emphasize that the part that shows is too much, may become irksome image.Therefore, under this situation, dredge (Inter between can carrying out the quantity of candidate portion according to certain rule and draw く), or the scope of constriction zone A.
Be no less than 5, be under the situation 5 or more in the result of determination of step S115 quantity, then, on every side in the scope of A portion, be used to produce the image processing of sparkle effect at this candidate portion and its for candidate portion.At first, in order to switch sparkle effect, whether there is face (S121) in the process decision chart picture according to situation.
Result of determination at step S121 is to comprise in the image under the facial situation, and establishing the stipulated time is t10(S122), on the other hand, in image, do not comprise under the facial situation, establishing the stipulated time is t20(S123).This stipulated time is the time that changes after the brightness of candidate portion to changing once more till the brightness.
In the present embodiment, shown in Fig. 7 (a), when changing the brightness of facial parts and it being glittered, (t10) carries out the switching of brightness so that it is not obvious as early as possible.On the other hand, shown in Fig. 7 (b), in the part beyond the face, slowly (t20) changes.In addition, in the present embodiment, (X, whether the point of Y) locating is face-image to the coordinate of judgement candidate portion, still, also can reflect the contrast of image.
After carrying out the setting of stipulated time, then, (X Y) be the center, generates and shows to it image (S124) after brightness of A portion increases on every side with the coordinate that write down.After increasing brightness, when passing through the stipulated time of in step S122, S123, setting, make the part that becomes bright get back to original brightness (S125).Then, judge that whether finishing luminous point emphasizes to show (S126).In operating portion 9, be provided with and be used to begin or finish luminous point and emphasize the functional unit that shows, in step S126, judge the mode of operation of this functional unit.In addition, also can carry out end, under this situation, take the luminous point of the finish time and emphasize image by the operation release-push.
Result of determination at step S126 is under the situation about having finished, returns the flow process of camera control described later.On the other hand, do not having to be chosen in coordinate (X, Y) (S127) of other candidate portions that write down among the step S113 under the situation about finishing.After selecting the coordinate of other candidate portions, return step S121, carry out above-mentioned action.
Like this, in the flow process that luminous point is emphasized to show, in step S101～S113, (coordinate (X, Y)) carries out record to it in the candidate portion that detection is brighter than regulation brightness B1 and brightness A portion around it does not all have B1 to become clear.Then,, comprise around this A portion and increase brightness successively, return to original brightness after at the appointed time interior at the candidate portion that this write down.By carrying out this action repeatedly, as Fig. 2 and shown in Figure 7, can to carry out with the still image be keynote, bring into play the image appearance of dynamic image effect simultaneously.
In addition, comprise candidate portion around A portion become bright in the interior candidate of making portion, A portion is set at the size that can not make us being fed up with and can see when showing around will be somebody's turn to do in advance, set and about 1/30 sizable rounded portions of whole image as default value.But by user's selection operation, this shape also can be to be equivalent to onesize other shapes such as star-like or rhombus, and in addition, size also is not limited to 1/30, can suitably change.In addition, also can change size and color etc. according to the feature of image section.Determined to carry out candidate portion that luminous point emphasizes and on every side after, control by synthetic control part 7, still, also can carry out the decision of the stipulated time among step S121～S123 by control part 1.
Then, use Fig. 9 that the concrete structure of the synthetic control part 7 that carries out image is synthetic is described.Synthetic control part 7 is made of gain assigning unit 7a, multiplier 7b, 7c and adder 7d.
That is, the output of the output of multiplier 7b and recording portion 3 and gain assigning unit 7a is connected, and connects into to adder 7d and export these multiplication results.Multiplier 7c is connected with the output of gain assigning unit 7a and the output of the light quantity increase 5b of portion, and connects into to adder 7d output multiplication result.Gain assigning unit 7a is connected with the output of the light quantity increase 5b of portion, and input has the synthetic timing signal from control part 1.Output according to the light quantity increase 5b of portion generates gain, and connects into to multiplier 7b, 7c and export this gain.Adder 7d connects into and imports each output that has from multiplier 7b, 7c, and connects into to efferent 8 these addition results of output.
The static image data of reading from recording portion 3 is output to multiplier 7b and candidate extraction portion 4.The coordinate information of the candidate portion that is extracted by candidate extraction portion 4 is output to peripheral light amount increase 5b of portion and mobile control division 5a.The peripheral light amount increase 5b of portion is from the positional information of candidate extraction portion 4 input candidate portions, and from mobile control division 5a input mobile message, generation has increased the image of peripheral light amount, and it is outputed to gain assigning unit 7a and multiplier 7c.
The action of the synthetic control part 7 that constitutes so then, is described.At first, candidate extraction portion 4 is extracted the candidate portion with light quantity increase effect from recording portion 3 input image datas.According to each pixel, in adder 7d to the candidate portion that extracts based on this and increased image after the peripheral light amount and original still image carries out addition.At this moment, at original still image in the suitable pixel of light quantity augmenting portion, utilize gain 0 in multiplier 7b, to multiply each other, synthetic light quantity increase image with gain 1 in multiplier 7c, multiply each other after, carry out addition.
It is synthetic to control this image by synthetic timing signal, after the beginning, finishes through after the stipulated time, and at this moment, the gain of establishing light quantity increase image is 0, and the gain of still image 38 originally is 1.Therefore, according to synthetic timing signal, gain assigning unit 7a changes gain between 0 and 1.As the variation of this gain, shown in Fig. 8 (a) and (b), increase in during from T1 to T2 and syntheticly emphasize luminous point with gain 37, get back to 0 in during from T2 to T3, make display image return to original image.
The variation of this gain has various variation, for example can select to become like that gradually bright pattern or become bright pattern suddenly shown in Fig. 8 (a) shown in Fig. 8 (b).Under this situation, can be made as:, if other images, then select the pattern of Fig. 8 (a) automatically if face-image is then selected the pattern shown in Fig. 8 (b) automatically.The pattern of the change in gain here is the sequential chart of the variation of the light in the candidate portion at a position, and the time that the coordinate of the candidate portion from show is transferred to the coordinate time of next candidate portion switches according to described stipulated time t10, t20.
This variation can be to select regularly, also can be to switch at random.In addition, also can switch according to image.For example, make the high part of contrast fast, make the low part of contrast slow.Can carry out showing accordingly with the atmosphere of image.
Here, Du the method for obtaining in the figure shown in Fig. 4 (b), (e), utilizes brightness height from regulation brightness B1 to peak value etc. to judge as a comparison, perhaps also can judge according to slope of this peak value portion etc.And, at step S121(Fig. 6) in, can consider that also contrast changes the stipulated time.Under the high situation of contrast,, then more effective if further enlarge the area of luminous point.And, also can be according to the tone of image, for example have blueness have white or the situation of grey under, being judged to be has cloud above picture, when luminous point enlarges, change size and regularly etc.
Then, use flow chart shown in Figure 10, the action that this camera that can reproduce the camera of demonstration is controlled is described.
After entering the flow process of camera control, at first judge whether be photograph mode (S201).This camera 10 can be set photograph mode and these two patterns of reproduction mode.Result of determination at step S201 is to be under the situation of photograph mode, transfers to photography and prepares.In addition, in the present embodiment, the displaying live view when photography is prepared can carry out the demonstration emphasized based on luminous point when showing.
After transferring to the photography preparation, at first be taken into image (S202).In this step, be taken into view data by photography portion 2, on liquid crystal display part 8a, carry out displaying live view according to this view data and show.And, use the view data that is taken into to detect whether there is facial parts, and under situation about existing, detect which position that is arranged in picture.Also can when photography, write down detected and facial relevant information in the lump here.If carry out record, then when reproducing, carry out luminous point when emphasizing to show, can not need to judge facial position.
Then, judge that whether carrying out luminous point emphasizes to show (S203).In this step, judge that whether having operated operating portion 9 interior luminous points emphasizes functional unit.Do not carry out common displaying live view according to the view data that is taken into and show (S204) under the situation that luminous point emphasizes for carrying out in this result of determination.On the other hand, be to have carried out luminous point to emphasize to carry out luminous point and emphasize to show (S205) under the situation of the operation that shows in the result of determination of step S203.
This luminous point emphasizes to show the flow process of carrying out use Fig. 6 explanation.Emphasize the flow process that shows as shown in Figure 7, to show to have the image that glitters by carrying out luminous point, enjoy the enjoyment of photography.And, on one side can before photography, direct viewing on one side confirm whether be to exist luminous point to emphasize the image of display effect.
Carry out that image shows or after luminous point emphasizes to show, then judge whether carried out releasing operation (S206).In this step, judge the release-push of whether having operated in the operating portion 9.
Result of determination at step S206 is under the situation about not discharging, and returns step S201, carries out described action.On the other hand, be under the situation of having carried out discharging in result of determination, begin photography and record (S207).Here, photography is still image photography or the dynamic image photography of being undertaken by photography portion 2.Under the situation of having operated release-push, also can be judged to be is the dynamic image photography, in addition, when the photography of dynamic image or still image, also can come recording voice by collection line 6.During reproduced image, can reproduce sound in the lump.During photography/record end, finish this flow process, return step S201 once more.
Result of determination at step S201 is to be not under the situation of photograph mode, judges whether be reproduction mode (S211).For being not under the situation of reproduction mode, return step S201 in this result of determination.On the other hand, be to be under the situation of reproduction mode in result of determination, carry out image and select (S212).In this step, for example carry out thumbnail and show, the image that the user is selected is as reproducing the candidate.
Then, S203 is same with step, judges that whether carrying out luminous point emphasizes to show (S213).For not being under the luminous point situation emphasizing to show, carry out the common reproduction of the image in step S212, selected in this result of determination.Under this situation, being under the situation of dynamic image selecting image, directly captured consecutive image being reproduced as dynamic image, is under the situation of still image selecting image, and the reproduction of directly carrying out still image shows.
And, be to have selected under the situation that luminous point emphasizes to show in the result of determination of step S213, carry out the luminous point that uses Fig. 6 explanation and emphasize the flow process (S215) that shows.Thus, as mentioned above, at the candidate portion that brightness is above for regulation and periphery is not stipulated the part of above brightness, carry out the synthetic processing of image successively so that it becomes bright, thus, can reproduce the image of the dynamic image style that glittering of display light move.The result of determination of step S213 for the situation of not selecting luminous point and emphasizing under, carry out common reproduction and show (S214).Carry out luminous point and emphasize demonstration or show the back end usually, begin execution from step S201 once more.
As described above, in the 1st execution mode of the present invention, extraction part as the edge of cloud is illuminated by sunlight, bright with comparing obvious change on every side is as candidate portion, make this candidate portion that extracts become bright brightness to regulation above after, return to original brightness once more.At a plurality of candidate portion, implement the image processing of this brightness change successively, thus, glittering of light moved successively.Therefore, different with simple still image, become the reproduction of dynamic image style, become the rich image that changes.Because image change, therefore just like can see landscape outside window and broaden extensively.
Then, use Figure 11～Figure 13 that the 2nd execution mode of the present invention is described.In the 1st execution mode, select candidate portion at random, in other words, not necessarily select candidate portion along continuous lines.Relative therewith, in the 2nd execution mode, judge whether be banded continuous light, select the candidate portion of continued presence, thus, carry out the luminous point of the bright part additional spot of band shape is emphasized to show.
In the structure of the present invention's the 2nd execution mode, be replaced into the flow chart shown in Figure 13 except luminous point shown in Figure 6 in the 1st execution mode being emphasized the flow chart that shows, identical with the 1st execution mode, so, be that the center describes with the difference.
At first, use Figure 11 and Figure 12 that the selection of the candidate portion of the 2nd execution mode is described.In the impressive image that glitters at the edge 31 of the cloud 30 shown in Figure 11 (a), performance has further been strengthened impression after having emphasized the sparkle effect of part at this edge 31.
Get the X-axis Y-axis shown in Figure 11 (a), when getting Luminance Distribution along the horizontal line 36a～36c along Y-axis, Luminance Distribution is shown in Figure 11 (b)～(d).Same with the 1st execution mode, take out the bright part of specific luminance B, when on the XY reference axis, describing the position 39a at the center of this part～39d, as shown in figure 12.
Here, position 39a～39c arranges in the scope of Rack x2 continuously as can be known.That is, can be judged as the brightness portion that position 39a～39c is continuous band shape.On the other hand, there is not the central point of other lights in position 39d in Rack x2, is not judged as banded brightness portion.In the present embodiment, because a plurality of points are not arranged in Rack x2, so, the light of position 39d in Figure 11 (a) (the right side peak value that is equivalent to Figure 11 (d)), do not select thisly, do not generate the synthetic image of using as luminous point as candidate portion.
Then, the luminous point that uses Figure 13 explanation to be used to carry out present embodiment is emphasized the flow process that shows.After entering the flow process that the luminous point of present embodiment emphasizes to show, same with the 1st execution mode, in step S101～S107, determinating area is moved respectively on X-axis and Y direction.In step S107, (X under the situation that the brightness ratio brightness B1 that Y) locates becomes clear, judges coordinate (X, Y) brightness about (S111A) being judged to be coordinate.
In addition, in the 1st execution mode, the brightness of A is judged around having carried out, still, in the 2nd execution mode, in order to simplify, only judge in the scope that enters A on every side about brightness.Certainly, same with the 1st execution mode, about being not limited to, the brightness around also can judging.Under this situation, in next step, whether A integral body is darker than B1 around judging.
Brightness according to step S111A is judged, then, judges whether left and right sides both sides' brightness is B1 following (S112A).In addition, as the brightness about here, the brightness of the pixel around judging in the A, and be not limited to the pixel of direct neighbor.The result of determination of this step S112A for around the left and right sides both sides' that comprised in the A brightness be not under the situation below the B1, return step S105.
On the other hand, under the result of determination of step S112A for both sides' brightness is situation below the B1, blotter coordinate (X, Y) (S117).Behind the blotter, judge that then coordinate X is whether in the scope of X ± X2 of blotter last time (S118).As illustrated in fig. 12, judge the banded scope that whether is positioned at.Here, X2 has considered error, for example is made as about several times the value of Δ X and Δ Y.In this result of determination is not under the situation in scope, returns step S105.
On the other hand, be to be positioned under the situation of prescribed limit in the result of determination of step S118, (X is Y) as candidate portion (S119) for the final entry coordinate.After writing down, return step S105 once more.Execution in step S102～S119 thus, can be recorded in the coordinate that is present in the candidate portion in the banded light in the picture repeatedly.
When the result of determination of step S103 is Y when reaching boundary value Y1, the judgement in the whole image finishes, so, then carry out the generation of luminous point.In the present embodiment, in order to carry out light (Y direction of Figure 11) mobile demonstration from top to bottom on picture, after step S131, according to Y data order from small to large candidate portion is carried out luminous point and emphasize.
At first, according to Y from small to large call over coordinate (X, Y) (S131) that is write down.Here, read out in the coordinate that writes down among the step S119.Then, (X, Y) portion is the center, generates and shows image (S132) after brightness to peripheral A portion increases with the coordinate read.Periphery A portion can be similarly rounded portions with the 1st execution mode, also can be other shape such as star-like.
Then, judge luminous point emphasizes to show whether finish (S133).On operating portion 9, be provided with and be used to begin and finish luminous point and emphasize the functional unit that shows, in step S133, judge the mode of operation of this functional unit.
Under the situation of result of determination of step S133, return the flow process of camera control for end.On the other hand, do not having to wait for the process stipulated time (S134) under the situation about finishing.Through after the stipulated time, return step S131, (X Y), carries out the demonstration of luminous point to read next coordinate.In the 2nd execution mode, not special judgement has or not face and contrast, still, can certainly be same with the 1st execution mode, judge to have or not face and judge contrast, come the stipulated time among the switch step S134.
Like this, in the 2nd execution mode of the present invention, judge in the banded scope whether have candidate portion (S118), only under the situation in candidate portion enters banded scope, final entry is a candidate portion.Therefore, can carry out the reproduction that luminous point flows.
As described above, in the of the present invention the 1st and the 2nd execution mode, in the image of photographs, detect bright candidate portion than regulation brightness B1, the A on every side that generates candidate portion is than the brighter synthetic image of using of regulation brightness, synthetic this composograph and original photographs reproduce this image.Therefore, can reproduce with shirtsleeve operation and can adapt to the image that utilizes television set etc. to appreciate.That is,,, thus,, can reproduce the image that demonstration has variation though photographs is a still image to the sparkle effect of the still image additional optical finished in the moment of taking with simple structure.
In addition, in the of the present invention the 1st and the 2nd execution mode, select candidate portion from stipulate above brightness, still, also the part of the luminance saturation of detected image simply selects this part to carry out image processing as candidate portion.And, when judging brightness, be not limited to actual brightness, can certainly use the light intensity that enters imaging apparatus of the aperture of having considered camera etc. or consider the various brightness such as brightness of the photosensitivity of time for exposure and imaging apparatus.
In addition, in the of the present invention the 1st and the 2nd execution mode, when selecting candidate portion, being made as above brightness of the 1st regulation and the brightness in the scope A all is not the above brightness of the 2nd regulation, and the 1st all is identical brightness with the 2nd regulation brightness.But the 1st and the 2nd stipulates that brightness can certainly be different.
In addition, in the of the present invention the 1st and the 2nd execution mode, when selection candidate portion, judge and stipulate above brightness and whole brightness of the brightness in the scope A, still, the also not interior brightness of limit of consideration A.Under this situation, also might be not obvious, still fully bright even generate luminous point by making luminous point, can make luminous point become obvious to a certain extent.
Then, use Figure 14～Figure 27 that the 3rd execution mode of the present invention is described.The camera 60 of the 3rd execution mode of the present invention also is a digital camera, can take continuous shooting and dynamic image, and in recording medium recording image data.And, during reproduction, extract the part that brightness changes in the image, this changing unit and benchmark image is synthetic, can reproduce the composograph that display brightness changes repeatedly.Thus, can access the effect of looking into the distance landscape carefree and contently.
Before the structure of the camera 60 that present embodiment is described, use Figure 15 and Figure 16 that the consideration method of the reconstruction of image in the camera 60 that image-reproducing means of the present invention has been installed is described.
Nearest digital camera can carry out the dynamic image photography simply, still, and along with the miniaturization of camera, cause that easily hand trembles, and, in the photography of dynamic image, shown in Figure 15 (c), beyond thought sometimes subject (being automobile 83 here) enters picture.When utilizing the television set 70 of this big picture of Figure 16 to reproduce this image, hand is trembled very irksome, and, see that repeatedly the curious coincidence image is also very irksome.
In addition, as the wallpaper of personal computer, when showing original photographs on big picture thin type television set 70, hand is trembled with the coincidence image also improper.If still image then can address this is that, and still image itself can be the image of constantly finishing in photography in the moment worksization of taking.Therefore, if still image does not then need to bother so, can satisfy general user.
But, utilizing big frame TV machine etc. to reproduce under the situation of display images, if fully without any changing then can feel dull and be sick of, so, can watch the image that some variations are arranged at leisure.For example, in this sight etc., can show glittering of this light on the wave that rock at tree 81 leaf, the reverberation of sunlight glitters this sight (with reference to Figure 15 (a) and (b)), light reflexes to the sea.Even the effect of the light that reflection of light etc. produce repeatedly at nature is repeatedly several times, do not have sticky feeling yet, there is the gentle effect of mental state that makes the appreciator.
Like this, though be this image that does not have great changes of still image,, additional reflection of lights etc. thus, can mirror just like the demonstration of landscape outside window in the variation of the recurrent light of nature.But, shown in Figure 15 (c),, can feel when repeatedly watching naturally and can be sick of though automobile 83 grades of passing through are to change part, so, this subject preferably do not reproduced.
According to this consideration method, in the image-reproducing means of present embodiment, reproduce the image that shows below: at the still image of constantly finishing in photography, only give the catoptrical variation of the sun, remove hand and tremble this ugly part, on the other hand, give the variation of the light of nature.Thus, as shown in figure 16, can on the television set 70 of big picture, show the image that mirrors landscape outside window.In addition, when the photography of dynamic image and continuous shooting image, also can record, when the reconstruction of image, reproduce tweedle tweedle etc.
Then, the above-mentioned structure that can reproduce the camera of display image is described.Figure 14 is the block diagram of electrical structure that the camera 60 of the 3rd execution mode is shown.Camera 60 has control part 51, photography portion 52, recording portion 53, the compression preservation 53b of portion, represents extraction unit 54, image change extraction unit 55, collection line 56, synthetic control part 57, efferent 58, liquid crystal display part 58a and operating portion 59.
Represent in the view data of extraction unit 54 from be recorded in recording portion 53 and extract representative image.Continuous shooting image and dynamic image are made of a series of a plurality of still images, represent extraction unit 54 to extract representative image from these a plurality of images.Image change extraction unit 55 compares representative image and each still image in a series of a plurality of still images that constitute continuous shooting and dynamic image, only extracts the part that changes.This image change extraction unit 55 is extracted the picture signal itself (part modified-image) that hands are trembled the part of brightness variation in the variable quantity that waits the integral image that causes to change, the image.
It is first-class that liquid crystal display part 58a is arranged on the back side of camera 60, reproduces the synthetic composograph of the document image of displayed record portion 53 and synthetic control part 57.Operating portion 59 comprises functional units such as release-push, menu button, and when the user operated operating portion 59, control part 51 was exported control signal according to operation to each one.
Then, use Figure 17～Figure 21 that the synthetic processing of image of present embodiment is described.Figure 17 illustrates the hand-held dynamic image of taking (or continuous shooting image).Shown in Figure 17 (a)～(c), this dynamic image is made of a series of still image, and in picture, tree 81 position is trembled and changed owing to hand.
Figure 18 (b), (c) as the representative image that becomes benchmark, illustrate the initial frame shown in Figure 18 (a) subject and how to change.Here, for easy, the vertically situation of (y direction) variation only is shown.Subject promptly set 81 image at vertical misalignment with consistent with representative image, detect difference side-play amount hour.If this minimum offset is variation delta y1, Δ y2.
When using variation delta y1, the Δ y2 obtain to come correction chart 17(b here), during the position of the subject shown in (c), as shown in figure 19.That is, the image of Figure 17 (b) the Δ y1 that moves up in the vertical, the image of Figure 17 (c) moves down Δ y2 in the vertical.
The leaf of tree 81 is owing to wind waves, and the reverberation of sunlight glitters.Change 82 about this part of glittering, part changes 82a, 82b, 82c and position thereof and at every moment changes.After using variation delta y1, Δ y2 to proofread and correct, the position of establishing part variation 82b, 82c is y1, y2.Figure 20 only extracts part to change 82a, 82b, 82c and make the picture signal of part in addition is the modified-image of minimum value.
Figure 21 illustrates representative image (benchmark image), is and Figure 17 (a), the identical image of Figure 18 (a).When changing 82 modified-image, can access image at the synthetic part that only extracts shown in Figure 20 of this representative image owing to waving of leaf glimmered and reverberation waves.According to this method, do not utilize the major part of dynamic image, only write down representative image (with reference to Figure 21), change point information (y1, y2 etc.) and modified-image (with reference to Figure 20) and get final product, so the data volume that can make image is a low capacity.And, when printing or when utilizing television set 70 etc. to appreciate still image, can enjoy the enjoyment that not have dynamic image shaken of the effect of having added light.
Then, use Figure 22 that the concrete structure of execution at the synthetic synthetic control part 57 of Figure 17～image illustrated in fig. 21 is described.Synthetic control part 57 is made of gain assigning unit 57a, multiplier 57b, 57c and adder 57d.
That is, gain assigning unit 57a is connected with the output of modified-image 55a, and connects into according to this modified-image 55a to multiplier 57b, 57c output gain.Multiplier 57b is connected with the output of gain assigning unit 57a and the output of modified-image 55a, and connects into to adder 57d output multiplication result.The output of the output of multiplier 57c and representative image 54a and gain assigning unit 57a is connected, and connects into to adder 57d and export these multiplication results.Adder 57d connects into and imports each output that has from multiplier 57b, 57c, and connects into to efferent 58 these addition results of output.
The action of the synthetic control part 57 that constitutes so then, is described.As from representing the representative image 54a of extraction unit 54 output, the image that uses shooting operation to obtain at first still, can certainly be the image when the most stable in cameraman image, dynamic image or the continuous shooting image selected.
From the modified-image 55a of image change extraction unit 55 outputs are described a series of a plurality of modified-images shown in Figure 20 (with reference to Figure 20 (b), (c)), and the part that part changes 82b, 82c is minimum value in addition.About the view data of this modified-image 55a, be input to multiplier 57b and gain assigning unit 57a successively according to each pixel.Modified-image 55a is a plurality of, when at an initial frame input image data, moves to next frame and carries out the data input repeatedly, till the view data of frame number-1 frame that input is taken continuously.
Gain assigning unit 57a changes gain according to the data of each pixel of modified-image 55a.That is, about the part that does not have to change, view data is made as minimum value.In view data is under the situation of minimum value, and the gain of establishing multiplier 57b is 0, and the gain of multiplier 57c is 1.On the other hand, about vicissitudinous part, the gain of establishing multiplier 57b is 1, and the gain of multiplier 57c is 0 etc., emphasizes the control of change section.In addition, also can change the gain of multiplier 57b gradually, also can emphasize to be more than 1.According to circumstances, also can change color or make it have variation.
When importing modified-image 55a(Figure 20 (b), (c) successively) time, at original representative image 54a(Figure 21) in the synthetic gradually part that changes and output to efferent 58.Therefore, reproduce by because the situation that the sunlight that the leaf that wind etc. wave reflects glitters.When this reproduces, only need original representative image 54a(Figure 21) and modified-image 55a(Figure 20 (b), (c)) view data get final product, do not need shown in Figure 19 being used to constitute the view data of a plurality of still images of dynamic image.
Then, use Figure 23 and flow chart shown in Figure 24, illustrate to be used to carry out in the synthetic action of Figure 17～image illustrated in fig. 21.Figure 23 is a flow process of extracting the change section of image.
After entering the flow process that changes extraction, at first, the variable n that expression is constituted the picture number of dynamic image is initialized as n=0(S501).In this example, the image during with dynamic image photography beginning is as benchmark image (representative image).Then, variable n is increased progressively (S502), judge whether this variable n after increasing progressively is the value (S503) corresponding with final frame.Arrive under the situation of final frame for variable n in this result of determination, turn back to original flow process.
Result of determination at step S503 is that variable n does not arrive under the situation of final frame, carries out the comparison (S504) of variable n and benchmark image (representative image), carries out the judgement (S505) of side-play amount (Δ Xn, Δ Yn).That is, as using Figure 18 explanation, on one side side-play amount is that migrated image is obtained consistent degree, the side-play amount when this unanimity degree is the highest on one side.
Then, carry out the detection (S506) of brightness change section (Xan, Yan).In this step, as illustrated in fig. 19, the part that sensed luminance changes detects its X coordinate and Y coordinate.Use Figure 26 and Figure 27 to narrate the details of this detection in the back.After the sensed luminance change section, then change section (Xan, Yan) view data in addition is made as minimum value (S507).That is, the view data beyond the changing unit is made as minimum value, is made as n new image (with reference to Figure 26 (d)).
After in step S507, generating n new image, it is recorded as the synthetic image n(S508 that uses).As above-mentioned shown in Figure 20, this is synthetic to be the image that only is made of the change section of brightness variation with image n.Record is synthetic to return step S502 with behind the image n, and n increases progressively to variable, carries out described action.
Then, the sub-process of using the brightness change section among Figure 26 and Figure 27 description of step S506 to detect.At first, use Figure 26 that the consideration method of the detection of brightness change section is described.Figure 26 (a)～(c) illustrates image shown in Figure 26 (e) along the horizontal Luminance Distribution of picture specified part.Though not clearly record on figure,, the transverse axis of Figure 26 (a)～(c) illustrates locations of pixels, and the longitudinal axis illustrates the output of each pixel.Brightness according to shot object image forms illustrated pattern.
Figure 26 (a) illustrates the LO-pattern of benchmark image (representative image), and Figure 26 (b) is a n image, and here, brightness increases Δ B.Then, the variable n of expression frame number further increases, when becoming n+m image, and the disappearance of glittering of changing unit.Like this, luminance difference Δ B increases, and then, gets back to original brightness.
In the present embodiment, not that the part detection that only brightness is changed is the brightness change section, after change is bright, judge whether get back to original brightness once more, will satisfy the part of this condition as the brightness change section.After detecting the part that satisfies this condition, the scope X1～X2 that establishes this part is Xan.At Y direction, utilize same consideration method, the change detected part, the scope Y1～Y2 that establishes this part is Yan.
After detecting change section Xan according to the consideration method of Figure 26 (a)～(c), the value of establishing beyond this change section is a minimum value, thus, shown in Figure 26 (d), can access composograph, with this composograph as new n image (with reference to S507).
Then, the action of using this brightness change section of flowchart text shown in Figure 27 to detect.As mentioned above, not to detect the bright part that just finishes of glittering once, whether return to original brightness but must detect it.That is, glitter and might not disappear in a flash, the object of the back disappearance a little while of glimmering as Christmas tree also exists, so whether utilization returns to original brightness is judged.
After entering the flow process of brightness change section detection, at first, n image after benchmark image (representative image) and the position correction compared the Xan of change detected portion, Yan(S801).In this step,, detect the part of the variation that produces luminance difference Δ B as illustrating in Figure 26 (a) and (b).Then, the brightness of establishing Xan, the Yan of benchmark image (representative image) is B0(S802).After n image detected, the brightness of benchmark image is stored as B0, whether gets back to original brightness once more so that judge the brightness of this part.
Then, judge whether there be n+1 image (S803).In this step, judge judge whether there is next image (n+1 image) at a series of still image end brightness of dynamic image and formation continuous shooting image.In this result of determination is to exist under the situation of n+1 image, obtains the Xan of this n+1 image, the brightness of Yan, establishes it and is B1(S804).
After obtaining brightness B1, then, judge this B1 and the B0 that in step S802, stores whether about equally (S805).In this result of determination for not being that n adds 1(S807 to variable under the situation about equally), return step S803, carry out above-mentioned action.In the process of carrying out step S803～step S807 repeatedly, in the judgement of step S805, B1 and B0 become about equally.Under this situation, be judged as the brightness variation and get back to original brightness.When the result of determination of step S805 is
The time, Xan, Yan as brightness change section (S806), are returned original flow process.
In the result of determination of step S803 for not exist under the situation of n+1 image, not with Xan, Yan as brightness change section (S808), return original flow process.Under this situation, though the part that exists local luminance to brighten is not got back to original brightness, so not as change section.Like this, even judge that whether getting back to original brightness is also not have not the part of sense naturally in order to select to change repeatedly.For example, the not the sense naturally even light of spectacular sign glimmers also repeatedly, still, be judged as change section if in photographic process, extinguished the bright portion of the window of electric light, make it that flicker meeting is unnatural repeatedly, so, in this case, not with it as change section.
Then, use the flow chart of synthetic demonstration shown in Figure 24, illustrate that composograph (modified-image) and the benchmark image (representative image) to obtaining by flow process shown in Figure 23 synthesizes the action that shows.
After entering the synthetic flow process that shows, at first, carry out initialization) so that the variable n of the order of expression composograph is 0(S601.Then, n adds 1 to variable, makes variable n increase progressively (S602).Then, whether judge to modified-image carried out handling to the last image, be variable n whether be last (end) (S603).
In the result of determination of step S603 is that composograph n is not under the last situation, carries out synthetic (S604) of benchmark image and composograph.Carry out this synthetic processing by the synthetic control part 7 that uses Figure 22 explanation.After in step S604, carrying out composograph n and benchmark image synthetic, return step S602, then, carry out the synthetic of composograph n+1 and benchmark image.Synthesize repeatedly up in step S603, be judged to be do not have composograph till.
Result of determination at step S603 is under the situation about having finished at last composograph, judges and whether has carried out end operation (S605).In this step, judge the end of whether having indicated synthetic demonstration by the functional units in the operating portion 59.For not carry out under the situation of end operation, return step S601 in this result of determination, once more from beginning to synthesize demonstration.
