(example with losing subject)

Illustrate with the situation losing subject below.Fig. 2 and Fig. 3 is an illustration for user P while holding the digital camera 1 as photographing unit, and the bird B that shooting flies a long way off is as the figure of the situation of an example of subject.Fig. 2 is an illustration for the user P figure that camera lens 3 does not carry out the state of zoom.

As in figure 2 it is shown, when bird B to be shot by user's P hand-held digital camera 1, user P observes the display picture 18a of display part 18, on one side the camera lens 3 of adjustment digital camera 1 towards.Camera lens 3, but without zoom, is not at the state of looking in the distance.

In fig. 2, the frame table of dotted line shows the image pickup scope IPA shot by image pickup part 14.Bird image BI is shown in smaller relative to whole picture on the display picture 18a of the display part 18 shown in frame of solid line.

Fig. 3 is an illustration for user P and camera lens 3 carries out zoom and figure to the situation that bird B shoots.As it is shown on figure 3, user P wants by the optical axis of camera lens 3 is carried out zoom towards bird B, and press shooting push button when showing and picture 18a amplifying display bird image BI, thus shooting bird B.In figure 3, the frame table of dotted line shows that user P is carrying out the zooming range ZA of zoom.

But, for user P, in order to make bird B be positioned at the approximate centre of the narrow angle of visual field, make the display picture 18a shown in the frame of solid line shows bird image BI and adjust digital camera 1 towards being very difficult.Such as, user P can make digital camera 1 towards the direction of the scope such as shooting the frame NZA shown in dotted line in figure 3 sometimes.

When bird B does not enter in the narrow angle of visual field of camera lens 3, owing to bird image BI disappears in display picture 18a, therefore, user cannot be carried out desired framing, and user is likely to observation bird B again, want on one side adjustment digital camera 1 camera lens 3 towards, or rely on display picture 18a, while observing display picture 18a, the camera lens 3 of logarithmic code camera 1 towards carrying out various change, until showing bird image BI.

Therefore, the digital camera 1 of present embodiment at this user P with when losing subject, the image in that shot by shoot part 14, bigger than zooming range ZA image pickup scope IPA is made to be shown on display part 18 as assistant images, thus user P can recognize that the direction that subject exists.That is, digital camera 1 is when user with, when losing subject, being switched to the image in image pickup scope IPA from zoom image, and be shown on display part 18, and user no longer with, when losing subject, displaying switching, shows zoom image on display part 18.

Furthermore, the pixel region on the imaging apparatus of the image pickup part 14 corresponding with zooming range ZA is actually constrained to the image recorded as photographs and has the image quality of more than predetermined image quality.That is, in digital camera 1, from predetermined Radix Rumicis to the predetermined zoom region being able to maintain that predetermined image quality, preferentially carrying out zoom by electronic zoom, when exceeding this predetermined zoom region, carrying out zoom by optical zoom.

Namely, digital camera 1 is when carrying out zoom operation, to the predetermined zoom position being able to maintain that predetermined image quality, preferentially carry out electronic zoom, when exceeding this predetermined zoom position, carry out optical zoom, and when carrying out zoom, when user P is with, when losing subject, being shown on display part 18 by the image of the image pickup scope IPA bigger than zooming range ZA.

Fig. 4 is an illustration for carrying out zoom and the figure of change of display image of display picture 18a with the display part 18 when losing subject.

When carrying out zoom, in the image pickup scope IPA of image pickup part 14 shooting, user carries out the image of the zooming range ZA of zoom and is shown on display picture 18a.But, when user detect with losing subject on the direction up and down color of the predetermined central part of mobile digital camera 1 or image pickup part 14 change or carry out the predetermined action such as the zoom operation to Radix Rumicis side rapidly or detect carried out scheduled operation time, on display picture 18a, in the scope (by the image pickup scope IPA that image pickup part 14 shoots) that period time (the such as 2 seconds) display of regulation is bigger than zooming range ZA.When having carried out this detection, user is in " seeing the state of losing ".

Although zooming range ZA is shown on display picture 18a by the zoom operation of user, but, digital camera 1 towards when drifting out from the position of subject, as shown in C1 in the diagram, display picture 18a does not show the image (bird image BI) of subject.

But, digital camera 1 is detecting that user is with, when losing subject, showing that the image being switched to image pickup scope IPA shows from the image of zooming range ZA so that in Fig. 4, the assistant images shown in C2 is shown on display picture 18a.

Image after switching, due to the image being the image pickup scope IPA bigger than zooming range ZA, therefore includes bird image BI sometimes.In the case of figure 4, owing to bird image BI is included in image pickup scope IPA, therefore, user can observe bird image BI, and the direction (in other words the direction of camera lens 3) of digital camera 1 becomes the direction of the bird image BI shown in arrow A.Furthermore, in this image pickup scope IPA, represent the frame ZF also overlapping display of zooming range ZA.

Therefore, user carry out zoom and with when losing subject, it is possible to by the direction that assistant images identification subject exists, and shoot subject with image quality more than predetermined image quality.

Alternatively, it is also possible to make user with the image of image pickup scope IPA shown when losing subject does not show the frame ZF representing zooming range ZA.

Fig. 5 is the schematic diagram illustrating the electronic zoom in zoom operation with the actuating range of optical zoom.In Figure 5, transverse axis represents zoom operation amount, and the longitudinal axis represents the zoom position of camera lens 3.If (during maximum Radix Rumicis) is 0 during the maximum field of view angle of camera lens 3, when carrying out the zoom of camera lens 3 when user operation operating portion 34, only electronic zoom plays a role in from maximum Radix Rumicis state (0) to the zoom area ZM1 of zoom operation amount Z1.That is, in zoom operation amount Z1 to the predetermined zoom position ZP1 of camera lens 3, the preferential action of electronic zoom.

The performance of the imaging apparatus according to image pickup part 14 pre-determines the predetermined zoom position ZP1 corresponding with zoom operation amount Z1.Determine zoom operation amount Z1, namely determine zoom position ZP1 so that the image quality carrying out the image of electronic zoom to zoom position ZP1 reaches more than predetermined image quality.It addition, user is when preparation digital camera 1 shoots sometimes, digital camera 1 towards subject but is made digital camera 1 towards other direction by this plan, but this produces when the angle of visual field is narrow.Thus, zoom position ZP1 can as the narrow zoom position of the angle of visual field, for instance as the angle of visual field zoom position less than 10 degree.Therefore, the preferential predetermined zoom region being carried out zoom by electronic zoom is that the visual field is narrow and the easy zoom area with the side of looking in the distance losing subject, when exceeding this zoom area, in order to prevent the deterioration of the image quality of photographs, carries out optical zoom.In Figure 5, solid line represents the action of electronic zoom.

This zoom operation amount Z1 or zoom operation amount ZP1 is stored in advance in the memorizer in signal processing and control portion 11 or in depositor.It addition, this zoom operation amount Z1 or zoom operation amount ZP1 also can be modified by user, the value after change is stored in the memorizer in signal processing and control portion 11 or in depositor.

CPU receives the focal length information of camera lens 3 via communication unit 12,32, and determines the zoom position ZP1 shown in Fig. 5 and zoom operation amount Z1 according to the area information (or user when preparation digital camera 1 shoots easily with the zoom position information losing subject) being able to maintain that predetermined image quality in the imaging apparatus of image pickup part 14.Zoom operation amount Z1 is the limit operation amount of electronic zoom, and zoom position ZP1 is the extreme zoom position of electronic zoom.

Such as, even if to imaging apparatus camera watch region 1/4, using electronic zoom function to shoot, if the image that obtains of shooting has the image quality of more than predetermined image quality, then predetermined zoom position ZP1 is set as 1/4 corresponding position of the camera watch region with imaging apparatus.Further, since this ratio changes according to the pixel count of imaging apparatus, therefore can also be 1/3,1/5 etc..Furthermore, this ratio also can according to the hobby of user, require level etc. and change.

Additionally, in the angle of visual field of the telescope end of optical zoom, it is possible to the region (being such as able to ensure that the region of the wide visual field angle of about 5 degree) of the angle of visual field more broader than this angle of visual field is arranged to the camera watch region of imaging apparatus.Or, in the angle of visual field of the telescope end of optical zoom, it is possible to such as in order to guarantee the more wide visual field angle of about 10 degree and carry out Zoom control.

Therefore, when user zooms to from Radix Rumicis side and to look in the distance side, in the maximum Radix Rumicis state (0) zoom area ZM1 to zoom operation amount Z1, carry out zoom by electronic zoom.That is, in the image pickup scope IPA shot by image pickup part 14, cut out the image after electronic zoom, and be shown on the display picture 18a of display part 18.

When zoom operation amount is more than Z1, the zoom position ZP1 of electronic zoom is fixed, and starts based on the optical zoom of the action of camera lens in camera lens 3.On the position of zoom operation amount Z1, not carrying out the zoom of optically-based zoom, when zoom operation amount is more than Z1, zoom position increases according to zoom operation amount.

In Figure 5, the line shown in chain-dotted line represents the action of optical zoom.That is, exceed in the zoom area ZM2 of zoom area ZM1 in zoom operation amount, electronic zoom is constrained to be fixed at zoom position ZP1, even if carrying out zoom operation further without action.On the other hand, in zoom area ZM2, to carry out optical zoom according to zoom operation amount so that being changed in the way of zoom position increase.In zoom area ZM2, zoom position as shown in broken line in fig. 5, be in conjunction with electronic zoom and optical zoom after position.

The image being shown on display part 18 becomes the image of image pickup scope IPA to correspond to the zoom position of the image being shown in display part in Figure 5 from the change in location of the some P1 corresponding with certain zoom position to the position of the some P2 of the zoom amount that have dropped electronic zoom from the image change of zooming range ZA.

The control of the electronic zoom corresponding with the zoom area shown in Fig. 5 and the actuating range of optical zoom is carried out by the range control section 11a in signal processing and control portion 11.

Next the display image on the display picture 18a being shown in display part 18 is illustrated.

Fig. 6 is an illustration for the image pickup scope of the imaging apparatus of image pickup part 14 and the figure of zooming range.It addition, the image that the display control unit 11b in signal processing and control portion 11 displays display picture 18a shows.In figure 6, the central part of image pickup scope IPA, area be about 1/4 be partially shown as the camera coverage limit range or camera coverage limit area that are able to maintain that predetermined image quality.

Now, even if optical zoom is to the focal length of about 400mm according to the conversion of 35mm film camera, it is also possible to adopt periphery to have about 5 degree field of view angle having more than needed.Certainly, if sacrificing image quality, additionally it is possible to corresponding with longer focal length.By so guaranteeing image quality and field of view angle, it is possible to be arranged in the digital camera that can find subject when losing subject at once.

As it has been described above, with the surplus capacity guaranteeing extended field of view angle when losing subject.When electronic zoom starts, the image pickup scope IPA for image pickup part 14 shooting cuts out the image of zooming range ZA, is shown on display picture 18a.That is, the surrounding image range PA shown in Fig. 6 bend is not explicitly shown on display picture 18a.If namely operation presses shooting push button, the image of zooming range ZA can record in the record medium in record portion 16.Further, generally, the image of the surrounding image range PA of the surrounding of zooming range ZA does not appear on display picture 18a.

Carry out electronic zoom from image pickup scope IPA to camera coverage limit range, but do not carry out in camera coverage limit range.

But, as described later, when user P being detected with the bird lost as subject, display picture 18a showing, the image (i.e. the image of the image of zooming range ZA and surrounding image range PA) of image pickup scope IPA is as assistant images.In other words, around image range PA is with display private part when losing.

Additionally, it is possible to reduce image (hereinafter referred to as the image around) PAP of image range PA around, and be shown on display picture 18a.

Fig. 7 is the figure of the example of the assistant images on the display picture 18a illustrating and being shown in display part 18.As it is shown in fig. 7, in the image of image pickup scope IPA, around the surrounding image PAP of image range PA is compressed and reduces display, inside it, amplify the zoom image ZAP showing zooming range ZA.

The state also comprising the image of image PAP around is shown under the state that Fig. 7 is shown as an example in 2 times of zooms.Illustrate: when setting the half of transverse direction of display picture 18a as 1, around the length of the transverse direction of image PAP is 1/4.That is, in order to reduce image PAP around, amplify zoom image ZAP, and these two images are converged in display picture 18a, namely in order to make and show that picture 18a's is in the same size or substantially uniform, change respective ratio and synthesize, generating assistant images.In other words, when detecting with when losing subject, microfilming is with extraneous surrounding image PAP, and according to photography reducing with extraneous image, the image of macrophotography scope, the image of the image having synthesized this image reduced and this amplification is shown on display part 18.Can by the operation of user, action, image change-detection go out this subject with losing.

Also being shown in by bird image BI as shown in Figure 7 on display picture 18a even if around image PAP is reduced, therefore, user P can know the direction of the optical axis towards camera lens 3.Additionally, zoom image ZAP is also shown on display picture 18a with the ratio that the ratio than the zooming range ZA in Fig. 6 Yu surrounding image range PA is big, therefore, user easily identifies photographs.

(process)

The following describes the process during photography of digital camera 1.Fig. 8 is the flow chart of the example of the handling process during photography illustrating digital camera 1.The CPU in signal processing and control portion 11 performs the process of Fig. 8.The process program of Fig. 8 is stored in the ROM (not shown) in signal processing and control portion 11.Additionally, Fig. 8 is the example setting the multiplying power that extreme zoom position ZP1 is camera lens 3, it is that being 2 times to multiplying power, electronic zoom carries out the situation of action.

During the power on of digital camera 1, CPU determines whether to be set by the user photograph mode (S1).When not being photograph mode (S1: no), perform other mode treatment, for instance, the process of reproduction mode.

When being photograph mode (S1: yes), CPU obtains the various data (S2) such as the focal length of camera lens 3, and determines whether auxiliary mode (S3).When with carrying out the pattern that auxiliary image shows when losing above-mentioned subject when this auxiliary mode is zoom, it is determined that whether digital camera 1 is set to auxiliary mode by user.The setting of auxiliary mode is carried out by the scheduled operation of the main part 2 of logarithmic code camera 1.Operating portion and the operation determination section 20 of main part 2 constitute mode setting part, and this mode setting part sets the auxiliary mode as preassigned pattern.

When digital camera 1 is not set to auxiliary mode, CPU determines whether to have carried out zoom operation (S4).When having carried out zoom operation (S4: yes), CPU performs optical zoom and controls operation (S5), and carries out region-wide display (S6).Region-wide display is to be shown on the display picture 18a of display part 18 by the region-wide image being shot the image pickup scope IPA obtained by the imaging apparatus of image pickup part 14.When not carrying out zoom operation (S4: no), CPU carries out region-wide display (S6).

It follows that determine whether to press shooting push button (S7), when pressing shooting push button (S7: yes), CPU stores the image (S8) of image pickup scope, processes and returns to S1.Additionally, when not pressing shooting push button (S7: no), process and return to S1.

When digital camera 1 is configured to auxiliary mode (S3: yes), CPU determines whether to have carried out zoom operation (S9).In zoom operation, CPU is respectively according to being able to maintain that region determined zoom area ZM1 and the ZM2 of predetermined image quality controls the action of electronic zoom and optical zoom in the imaging apparatus according to image pickup part 14.

In addition, in zoom operation, user by digital camera 1 set from photograph mode be altered to auxiliary mode, in S9, for making zoom operation continuously perform, the position corresponding with zoom operation amount from the S5 before the setting being altered to auxiliary mode carries out zoom operation.

When carrying out zoom operation (S9: yes), CPU, by whether the multiplying power of zoom operation judgement camera lens 3 is to 2 times (S10), if multiplying power is to 2 times, then carries out electronic zoom (S11) corresponding with zoom operation amount.Whether the multiplying power of camera lens 3 is the whether judgement in the scope of zoom area ZM1 corresponding to zoom operation amount in Figure 5 of the judgement to 2 times.

It addition, listing multiplying power here is the example of 2 times, but the telescope end of the image quality required by user, the performance of imaging apparatus, optical zoom, and multiplying power is alternatively other value.

When multiplying power is more than 2 times, CPU fixes electronic zoom (S12), and performs optical zoom corresponding with zoom operation amount control operation (S13).The multiplying power situation more than 2 times is in Figure 5 corresponding to zoom operation amount situation in the scope of zoom area ZM2.The process of S9～S13 is performed by range control section 11a.Thus, S9～S13 processes the process constituting zoom control section, and it, according to the zoom operation for camera lens 3, carries out Zoom control so that carry out electronic zoom in predetermined zoom region, and carry out optical zoom when beyond predetermined zoom region.

After the process of S11 and S13, CPU judges that whether user is with losing subject (S14).This decision method is described below.

Without with losing (S14: no), then CPU display selects area image, namely shows the image (S15) of zooming range ZA.But, with (S14: yes) when losing, CPU carries out region-wide display, namely at the image (S16) of predetermined period (during here for 2 seconds) display image pickup scope IPA.Although it addition, here with showing region-wide (image of image pickup scope IPA) when losing, but the image of the scope bigger than zooming range ZA also can be shown.That is, with when losing subject, it is shown on the display picture 18a of display part 18 than the image of big for the zooming range ZA scope in the image pickup scope of imaging apparatus.

Furthermore, with when losing, CPU can not carry out region-wide display (or the image of the scope bigger than zooming range ZA shows) for the time being yet, and gradually extends viewing area from zooming range ZA.Such as, according to being judged to that the action with losing is controlled, to extend viewing area.Further, after S15 and S16, process and enter into S7.The process of S14～S16 is performed by display control unit 11b.Thus, S14～S16 processes the process constituting display control unit, the display of display picture 18a, detecting that subject is with when losing, is controlled so that the image outside zooming range in the image pickup scope of imaging apparatus is shown on the display picture 18a of display part 18 by it.

It addition, in the above example, whole changing camera lens for what install, multiplying power to 2 times, only electronic zoom carries out action, however, it is possible to according to the camera lens installed, change only electronic zoom and carry out the multiplying power of action.Such as, in the zoom lens of relatively Radix Rumicis and the zoom lens relatively looked in the distance, it is possible to make electronic zoom carry out the scope of action different.Such as, due to when the zoom lens of Radix Rumicis, relatively low with the probability losing subject, therefore, can be set as until multiplying power is that 2 times of electronic zooms carry out action, due to when the zoom lens looked in the distance, higher with the probability losing subject, therefore, can be set as until multiplying power is that 3 times of electronic zooms carry out action.

In this case, the multiplying power judged in S10 is different in the zoom lens of relatively Radix Rumicis and the zoom lens relatively looked in the distance, and, in the zoom lens of relatively Radix Rumicis and the zoom lens relatively looked in the distance, the level of the image quality ensured is different.

Fig. 9 is the flow chart of the example with the flow process losing determination processing of the S14 illustrating Fig. 8.First, the CPU output according to the acceleration transducer of motion detection unit 15, presence or absence as the vibration of photographing unit or action, for instance judge whether there is the action be more than or equal to predetermined value on above-below direction or left and right directions, namely whether there is the action (S21) in direction up and down.Such as, predetermined value is the present angle of visual field, in S21, when there is the action of more than the present angle of visual field, it is determined that for there is the action in direction up and down.S21 constitutes the process of the motion detection unit of the action judging photographic equipment.Although it addition, detect the action up and down of photographing unit here, but the action of the rotation relative to optical axis and incline direction can certainly be detected.

When being absent from the action in direction up and down (S21: no), presence or absence as the change of the image in picture, for instance judge whether there is change (S22) by the color of the central part in the image that the imaging apparatus of image pickup part 14 obtains.CPU monitors the color of this central part all the time, for instance, it is determined that whether the color of central part belongs to one of prespecified multiple form and aspect, and when the form and aspect belonging to the color of central part change, it is determined that there is change in the color for central part.Or, for instance when chasing the white bird flying over sky as subject, when only have taken the sky of blueness with losing bird, the color of central part is changing into blueness from white, therefore, in this case, it is determined that the color for central part exists change.S22 constitutes the process of color change test section, the color change of the central part of the image of the image pickup scope IPA of its detection imaging apparatus.

Although it addition, detect the change of color herein, but the change of the change of brightness, shape also can be detected, it is possible to detection color, brightness and shape at least both change replace the change of color.Such as, the change of brightness is when brightness value there occurs the change of more than predetermined ratio, it is determined that there occurs change for brightness.About the change of shape, calculated the characteristic quantity of the shape of subject in central part by CPU and monitor all the time, when this characteristic quantity there occurs the change of more than reservation threshold, it is determined that there occurs change for shape.

And, when the color of central part does not change (S22: no), presence or absence as the operation of user, for instance judge that whether the zoom operation towards Radix Rumicis side that user carries out for operating portion 34 is the zoom operation (S23) rapidly of more than scheduled volume.Such as, when camera lens 3 has zoom ring, when zoom ring is around the axle rotation more than 30 degree of camera lens 3, it is determined that for there is zoom operation rapidly.When camera lens 3 has Zoom switch, when pressing the Zoom switch situation of pressure transducer (Zoom switch have) more at full tilt or pressing predetermined time more than (such as more than 1 second), it is determined that for there is zoom operation rapidly.It addition, this judgement also can carry out in zoom.

When the zoom operation that the zoom operation towards Radix Rumicis side that user carries out is not rapidly (S23: no), CPU is not judged to that user is with losing subject (S24).But, when being "Yes" in any one of S21, S22, S23, CPU is judged to that user is with losing subject (S25).

As mentioned above, the vibration of the photographing units such as the presence or absence according to action up and down or action, central part color the picture such as change in the change of image or the operation of the user such as the zoom operation rapidly towards Radix Rumicis side, the setting operation for auxiliary mode, it is determined that subject with losing.

The following describes the example reducing method of the surrounding image PAP of surrounding image range PA in the region-wide display of S16.Figure 10 is an illustration for the figure of the example reducing method of the surrounding image PAP of image range PA around.The process of the S16 shown in Figure 10 is performed by display control unit 11b.

First, the zooming range ZA in the image pickup scope IPA of imaging apparatus and the image range PA of surrounding about is shown about the D1 of CPU, Figure 10.Around image range PA is divided into 8 region R1～R8.In the example of Figure 10, zooming range ZA is set to the 1/4 of image pickup scope IPA.

As shown in the D2 of Figure 10, the cut zone (region shown in R1, R3, R6, R8) in 4 corners dwindles into 1/2 respectively on longitudinal direction and transverse direction.In addition, upper and lower cut zone (R2, region shown in R7) dwindle into 1/2 in the vertical direction, in the lateral direction, the numerical value (being 1.5 in this example) obtained according to the length L2 of the transverse direction with the zooming range ZA length L1 except the transverse direction being combined with R1 and R2 in D1 is amplified.Furthermore, the cut zone (region shown in R4, R5) of left and right zooms into 1.5 times in the vertical direction, dwindles into 1/2 in the lateral direction.It addition, minification can be the ratio beyond 1/2, for instance 1/3 etc., amplification can also be the ratio beyond 1.5 times matched with this minification, for instance 2 times etc..

D3 illustrates the state reducing display side images PAP as described above.In D3, owing to zooming range ZA is to maintain the size of former state, as shown in D4, therefore amplify zoom image ZAP.

As a result of which it is, owing to showing just like the assistant images shown in D4 on display picture 18a, therefore, the image of the subject that user P is able to confirm that in side images PAP.

It addition, the method that reduces of the side images PAP of side images scope PA is not limited to method illustrated in figure 10 above.Such as, when above-mentioned Figure 10, in direction up and down, merely amplify according to predetermined multiplying power and reduce, but it is also possible to more arrive the periphery of side images PAP, more changing proportion of deformation.Such as, according to the distance to periphery, the ratio etc. reducing or amplifying is changed.Namely, it is possible to make the minification in the reducing of the extraneous image of photography and photography scope image amplification in amplification at least one according to from the distance of the central part of the image pickup scope IPA of the imaging apparatus of image pickup part 14 and different.

As mentioned above, the photographic attachment of present embodiment have user be able to confirm that when losing subject outside zooming range with losing reply function, and the photographic attachment according to present embodiment, can while preventing the image quality aggravation of photographs, in other words, while maintaining predetermined image quality, the photography of subject is carried out.

Additionally, in the above-described embodiment, when digital camera 1 is set to auxiliary mode, when detecting that subject is with when losing, although the image in zooming range in the image pickup scope of imaging apparatus and the image outside the zooming range in the image pickup scope of imaging apparatus are shown on the display picture 18a of display part 18, but when setting auxiliary mode, by user's setting to auxiliary mode, display control unit 11b also can control the display of display picture so that the image in zooming range and the image outside zooming range are shown on the display picture 18a of display part 18 all the time.Namely, user when auxiliary mode in order to make the image in zooming range and the image outside zooming range be shown on the display picture 18a of display part 18 all the time, when logarithmic code camera 1 is set, even if detecting that subject is with losing, the image in zooming range and the image outside zooming range is also made to be shown on the display picture 18a of display part 18.

In this case, for instance, the display picture 18a of display part 18 shows the image pickup scope IPA of the imaging apparatus of image pickup part 14.Further, in order to the image in difference zooming range and the image outside zooming range, following process is carried out: the image surrounding in zooming range by wire；Image outside zooming range adds top shadow；Show the image in zooming range with colour and with white and black displays zooming range outside image etc..As a result of which it is, user is capable of identify that coverage.This is when being bad at subject framing often with effective when losing the user of subject or use zoom ratio is high and the angle of visual field is narrow zoom.

Additionally, may also set up 2 auxiliary modes, when digital camera 1 is set to 1 auxiliary mode, only detecting that subject is with when losing, the image outside the zooming range in the image pickup scope of the image in the zooming range in the image pickup scope of imaging apparatus and imaging apparatus is made to be shown on the display picture 18a of display part 18, when digital camera 1 is set to 2 auxiliary mode, the image in zooming range and the image outside zooming range are shown on the display picture 18a of display part 18 by display control unit 11b all the time.

(the second embodiment)

The following describes second embodiment of the present invention.

(structure)

The photographic attachment of the second embodiment has for shooting " moon " moon photograph mode as subject.The structure of the photographic attachment of the second embodiment is roughly the same with the structure of photographic attachment illustrated in the first embodiment, therefore, mainly explained below in the photographic attachment of the second embodiment, the structure different from the camera head of the first embodiment.

About " moon " as subject, due to deep or light contrast high be only profile portion, therefore, the part beyond the profile portion of moon image can suppress contrast to carry out noise removal process.Namely, even if reducing the part (namely significantly zoom) cut out from the photographed images from imaging apparatus, also being able to obtain the image that comparison is beautiful, " moon " accordingly, as subject can be called the subject corresponding with the present embodiment effectively utilizing electronic zoom.

Thus, owing to reducing above-mentioned zooming range ZA, and only in the assistant images of display when losing " moon " around the part of image PAP relatively wide, therefore, user can hold the probability of the position of " moon " and raise.

Figure 11 is an illustration for the user P figure that camera lens 3 does not carry out the state of zoom.

As shown in figure 11, when moon M to be shot by user's P hand-held digital camera 1, user P observes the display picture 18a of display part 18, on one side the camera lens 3 of adjustment digital camera 1 towards.Camera lens 3, but without zoom, is not at the state of looking in the distance.

In fig. 11, the frame table of dotted line shows the image pickup scope IPA shot by image pickup part 14.Moon image MI is shown in smaller relative to whole picture on the display picture 18a shown in frame of solid line.

Figure 12 is an illustration for user P and camera lens 3 carries out zoom and figure to the situation that moon M shoots.As shown in figure 12, user P wants by the optical axis of camera lens 3 is carried out zoom towards moon M, and presses shooting push button when showing and amplifying display moon image MI on picture 18a, thus shooting moon M.In fig. 12, the frame table of dotted line shows that user P is just carrying out the zooming range ZA of zoom.

But, as illustrated by the first embodiment, for user P, in order to make moon M be positioned at the approximate centre of the narrow angle of visual field, and make moon image MI be shown on the display picture 18a shown in the frame of solid line to adjust digital camera 1 towards being very difficult.

Here the size of the size of the moon and the imaging surface of imaging apparatus is illustrated.Figure 13 and Figure 14 is an illustration for being formed the figure of the size of the picture of the moon in the imaging surface of imaging apparatus.

As shown in figure 13, about there are 30 subangles (namely about 0.5 degree) (15 subangles of its half shown in Figure 13) due to the moon, therefore, in order to make the moon occupy in the image pickup scope IPA of the imaging surface 14a of imaging apparatus as M ' 1/3 area, according to following formula (1) and (2), it is determined that need the camera lens according to (longitudinal 24mm) conversion of 35mm film with the focal length Ft of 900.

Ft tan (1/4 degree)=4mm...... formula (1)

Ft=4mm/ (tan (1/4 degree))=900mm...... formula (2)

It is large-scale owing to being in general equivalent to the camera lens of 900mm, therefore, is only capable of on the small-sized photographing unit being easier to hand-held carrying and carries or install the optical zoom of about 300mm.

But, if having the words of the imaging apparatus of 20,000,000 pixels, even if carry out cutting the camera picture of the imaging surface 14a of image pickup scope IPA 1/9 3 times of zooms, it also is able to the image after carrying out this zoom guarantees the image quality of 2,000,000 pixels, therefore, its image has the image quality that can show in HDTV.

Figure 14 is an illustration for there occurs the figure of situation about once shaking in the camera lens of 30Omm.As shown in figure 14, when hand held camera prepares shooting, the shake be once equivalent to is there occurs relative to optical axis C, but, if having the angle of visual field of the camera lens of 300mm, even if there is user P in the angle of visual field of 900mm with the situation losing moon M, if the image by above-mentioned image pickup scope IPA is shown as assistant images, moon image MI is also contained in assistant images, and therefore user P will not with losing moon M.

Figure 15 is an illustration for the figure of the image being shown in assistant images.As shown in figure 14, with when losing the moon under the zoom state of 900mm, although the assistant images of the scope of the region E shown in dotted line is shown on display picture 18a, but assistant images comprises moon image MI outside zooming range ZA.

Figure 16 is an illustration for the figure of the operation for digital camera of present embodiment.User carries out predetermined operation by the operating portion 20A of logarithmic code camera 1, for instance presses moon photograph mode and sets the operations such as button, makes digital camera 1 be set to moon photograph mode.Operating portion 2OA and the operation determination section 20 of main part 2 constitute mode setting part, and this mode setting part sets moon photograph mode as predetermined pattern, in moon photograph mode, " moon " is shot as subject.

(process)

Next process during the moon photograph mode of digital camera 1 is described.Figure 17 is the flow chart of the example of the handling process during moon photograph mode illustrating digital camera 1.The CPU in signal processing and control portion 11 performs the process of Figure 17.The process program of Figure 17 is stored in the ROM (not shown) in signal processing and control portion 11.

It addition, in fig. 17, give identical label for process identical with Fig. 8, and explanation is simplified, omit a part.Additionally, illustrate to be set to the position being suitable for above-mentioned high-definition image (HD) extreme position of electronic zoom here, set the situation of zoom operation amount or zoom position.That is, in Figure 5, zoom position ZP1 is set to the zoom position of applicable high-definition image (HD).

When the power on of digital camera 1, CPU determines whether to be set by the user photograph mode (S1).When not being photograph mode (S1: no), perform other mode treatment, for instance the process of reproduction mode.

When being photograph mode (S1: yes), CPU obtains the various data (S2) of camera lens 3, and determines whether moon photograph mode (S31).This moon photograph mode as illustrated in fig. 16, according to by user, whether digital camera 1 is set to that moon photograph mode judges.

When digital camera 1 is not set to moon photograph mode, CPU performs the process from above-mentioned S4 to S8.

When digital camera 1 is set to moon photograph mode (S31: yes), owing to being the shooting moon, therefore setting focusing position at a distance, CPU determines whether to have carried out track in (zoomup) operation (S32).When having carried out track in operation (S32: yes), CPU determines whether that the high-definition image (HD) of the central part of the imaging apparatus at image pickup part 14 is suitable in the scope in portion and has carried out zoom (S33).

CPU passes through zoom operation, has carried out, during zoom (S33: yes), carrying out electronic zoom (S11) corresponding with zoom operation amount in the scope in the applicable portion of high-definition image (HD).Pass through zoom operation, the scope exceeding the applicable portion of high-definition image (HD) carries out during zoom (S33: no), CPU fixes electronic zoom (S12), and performs optical zoom corresponding with zoom operation amount control operation (S13).Zoom operation amount exceedes the situation of the position ZP1 of high-definition image (HD) limit corresponding to zoom operation amount situation in the scope of zoom area ZM2.

The process of S32～S13 is performed by range control section 11a.Thus, S32～S13 processes the process constituting zoom control section, and it, according to the zoom operation for camera lens 3, carries out Zoom control so that carry out electronic zoom in predetermined zoom region, and carry out optical zoom when beyond predetermined zoom region.

After the process of S11 and S13, CPU judges that whether user is with losing subject (S14).This decision method is identical with the process shown in above-mentioned Fig. 9.Owing to the contrast of " moon " is higher, therefore the process (detection with presence or absence of the color change of central part processes) of the S22 in Fig. 9 particularly effectively plays a role.

Not with the words (S14: no) lost, CPU display selects area image, namely shows the image (S15) of zooming range ZA.But, with (S14: yes) when losing, CPU is displayed on the image on display picture 18a, expands the region E of the scope that " moon " does not expose from zooming range ZA, and is shown on display picture 18a (S24).Thus, S14～S34 processes the process constituting display control unit, the display of display picture 18a, detecting that subject is with when losing, is controlled so that the image outside zooming range in the image pickup scope of imaging apparatus is shown on the display picture 18a of display part 18 by it.

Although also can when with the region-wide display carrying out image pickup scope IPA when losing " moon ", but, in the present embodiment, cut out the region E of the scope that " moon " does not expose, amplify the image of this region E cut out, and be shown as assistant images.Thus, the image of the region E cut out comprises the image of all " moon ".It addition, the image of the region E cut out also can not comprise the image of all " moon ", it is possible to comprise a part (such as half).

In fig .15, shown in dotted line, cut out the image of the moon image MI scope E not exposed, till being amplified to the size of display picture 18a, and be shown on display picture 18a.The process of S24 is performed by the display control unit 11b in signal processing and control portion 11.

In image pickup scope IPA, in the region E of the scope do not exposed to " moon ", owing to the contrast of " moon " Yu background is higher, therefore, it is possible to cut out the moon image MI scope do not exposed from the center of image pickup scope IPA by image procossing.

Namely, with losing " moon " period, the image of the scope E that moon image MI does not expose displays while changing size continuously, therefore, user can adjust the center moving to display picture 18a towards so that the position of " moon " of digital camera 1A glibly.

As mentioned above, photographic equipment according to present embodiment, when " moon " is carried out zoom shot, have user be able to confirm that when losing " moon " outside zooming range with losing reply function, and the photographic attachment according to present embodiment, while preventing the image quality aggravation of moon image, in other words while maintaining predetermined image quality, the shooting of subject can be carried out.

Additionally, in the above-described embodiment, when digital camera 1A is set to moon photograph mode, when detect " moon " with when losing, although the image cutting out the moon image MI scope E not exposed is amplified to the size of display picture 18a, and it is shown on display picture 18a, but when being configured to moon photograph mode, by the setting that user carries out, display control unit 11b also can control the display of display picture so that the image of the scope E that moon image MI does not expose is shown on the display picture 18a of display part 18 all the time.Namely, user when moon photograph mode in order to make the image of the moon image MI scope E not exposed be shown in all the time on the display picture 18a of display part 18, logarithmic code camera 1A is set time, even if detecting that " moon " is with losing, the image of the scope E that moon image MI does not expose is also shown on the display picture 18a of display part 18.

Now, the display picture 18a of display part 18 shows the image of the moon image MI scope E not exposed.Further, in order to distinguish image in zooming range and the image of scope E that moon image MI does not expose, carry out surrounding the process of image etc. in zooming range by wire.As a result of which it is, user can recognize that coverage.This is when being bad at subject framing often with being effective when losing the user of subject or use zoom ratio is high and the angle of visual field is narrow camera lens.

In sum, the photographic equipment according to above-mentioned two embodiment, using the teaching of the invention it is possible to provide a kind of user of having is with the photographic equipment of reply function when losing subject and the shooting that can carry out subject while preventing the image quality aggravation of photographs.

In particular according to the picture pick-up device of above-mentioned two embodiment, user can identify the direction of subject intuitively, in other words towards the direction of digital camera.

The invention is not restricted to above-mentioned embodiment, various alterations and modifications etc. can be carried out in the scope of objective of the present invention not changing.
