(with losing the example of being taken the photograph body)
Down in the face of describing with losing the situation of being taken the photograph body.Fig. 2 and Fig. 3 are used to explain that user P controls the digital camera 1 as camera on one side, take the bird B a long way off fly figure as the situation of an example being taken the photograph body on one side.Fig. 2 is used to explain that user P does not carry out the figure of the state of zoom to camera lens 3.
As shown in Figure 2, when user P hand-held digital camera 1 will be taken bird B, on one side user P observes the display frame 18a of display part 18, Yi Bian adjust digital camera 1 camera lens 3 towards.Camera lens 3 does not also have zoom, is not in the state of looking in the distance.
In Fig. 2, the frame table of dotted line shows the image pickup scope IPA that is taken by image pickup part 14.Bird image B I is presented at respect to whole image on the display frame 18a of the display part 18 shown in the frame of solid line lessly.
Fig. 3 is the figure that is used to explain the situation that user P carries out zoom to camera lens 3 and bird B is taken.As shown in Figure 3, user P wants to carry out zoom through the optical axis with camera lens 3 towards bird B, and under the state of enlarged and displayed bird image B I on the display frame 18a, presses shooting push button, thereby takes bird B.In Fig. 3, the frame table of dotted line shows that user P is carrying out the zooming range ZA of zoom.
But, concerning user P, be positioned at the approximate centre of the narrow angle of visual field in order to make bird B, the display frame 18a shown in the frame of solid line is gone up show bird image B I and adjust digital camera 1 towards being very difficult.For example, user P can make digital camera 1 towards the direction such as the scope of taking the frame NZA shown in the dotted line in Fig. 3 sometimes.
Under the situation in bird B does not get into the narrow angle of visual field of camera lens 3, because bird image B I disappears in display frame 18a, therefore; The framing that the user can't expect, on one side the user possibly observe bird B once more, Yi Bian want to adjust digital camera 1 camera lens 3 towards; Perhaps rely on display frame 18a; Observe on one side display frame 18a, on one side logarithmic code camera 1 camera lens 3 towards carrying out various changes, till showing bird image B I.
Therefore; The digital camera 1 of this execution mode at this user P with losing when being taken the photograph body; Make take by shoot part 14, be presented on the display part 18 as assistant images than the image in the big image pickup scope IPA of zooming range ZA, thereby user P can identify and taken the photograph the direction that body exists.That is, digital camera 1, switches to the image in the image pickup scope IPA from zoom image, and is presented on the display part 18 with losing under the situation of being taken the photograph body the user, and the user no longer with losing when being taken the photograph body, shows switching, on display part 18, shows zoom image.
Moreover in fact the pixel region on the imaging apparatus of the image pickup part 14 corresponding with zooming range ZA is constrained to as photographs and comes images recorded to have the image quality more than the predetermined image quality.That is, in digital camera 1,, preferentially carry out zoom, when surpassing this predetermined zoom zone, carry out zoom through optical zoom through electronic zoom regional to the predetermined zoom that can keep predetermined image quality from predetermined wide-angle.
That is, digital camera 1 is when carrying out zoom operation, till the predetermined zoom position that can keep predetermined image quality; Preferentially carry out electronic zoom; When surpassing this predetermined zoom position, carry out optical zoom, and under the situation of carrying out zoom; When user P with losing when being taken the photograph body, the image of image pickup scope IPA that will be bigger than zooming range ZA is presented on the display part 18.
Fig. 4 is used to explain carry out zoom and with the figure of the variation of the display image of the display frame 18a that loses the display part 18 when taking the photograph body.
When carrying out zoom, in the image pickup scope IPA that image pickup part 14 is taken, the image that the user carries out the zooming range ZA of zoom is presented on the display frame 18a.But; When the user with lose taken the photograph body and detect color at the predetermined central portion of mobile digital camera 1 or image pickup part 14 on the direction up and down change, or carry out rapidly to the predetermined action such as zoom operation of wide-angle side or detect when having carried out scheduled operation; On display frame 18a, during official hour (for example 2 seconds), show the scope bigger (through the image pickup scope IPA of image pickup part 14 shootings) than zooming range ZA.When having carried out this detection, the user is in " seeing the state of losing ".
Though zooming range ZA is presented on the display frame 18a through user's zoom operation; But; Digital camera 1 towards when depart from out the position of being taken the photograph body, as among Fig. 4 shown in the C1, on display frame 18a, do not show the image (bird image B I) of being taken the photograph body.
But digital camera 1 is detecting the user with losing when being taken the photograph body, shows that from the image of zooming range ZA the image that switches to image pickup scope IPA shows, makes that the assistant images shown in the C2 is presented on the display frame 18a among Fig. 4.
Therefore image after the switching includes bird image B I sometimes owing to be the image of the image pickup scope IPA bigger than zooming range ZA.Under the situation of Fig. 4, because bird image B I is included in the image pickup scope IPA, therefore, the user can observe bird image B I, and the direction (the in other words direction of camera lens 3) of digital camera 1 is become the direction of the bird image B I shown in the arrow A.Moreover, in this image pickup scope IPA, the also overlapping demonstration of frame ZF of expression zooming range ZA.
Therefore, the user with losing when being taken the photograph body, can be taken the photograph the direction that body exists carrying out zoom through assistant images identification, and takes with the image quality more than the predetermined image quality and to be taken the photograph body.
In addition, the user is followed lose in the image of the image pickup scope IPA that is shown when taking the photograph body the not frame ZF of data representing zooming range ZA.
Fig. 5 is the sketch map that the actuating range of electronic zoom and optical zoom in the zoom operation is shown.In Fig. 5, transverse axis is represented the zoom operation amount, and the longitudinal axis is represented the zoom position of camera lens 3.If when wide-angle (maximum) is 0 during the maximum field of view angle of camera lens 3, when carrying out the zoom of camera lens 3 when user's operating operation portion 34, only electronic zoom plays a role in from maximum wide-angle state (0) to the zoom area ZM1 of zoom operation amount Z1.That is, arriving till the predetermined zoom position ZP1 of camera lens 3 among the zoom operation amount Z1, electronic zoom preferentially moves.
Performance according to the imaging apparatus of image pickup part 14 is confirmed the predetermined zoom position ZP1 corresponding with zoom operation amount Z1 in advance.Confirm zoom operation amount Z1, promptly confirm zoom position ZP1, the image quality that obtains carrying out till the zoom position ZP1 image of electronic zoom is reached more than the predetermined image quality.In addition, the user is when preparing to take with digital camera 1 sometimes, and this plan is taken the photograph body with digital camera 1 towards quilt but made digital camera 1 towards other direction, but this is created in the angle of visual field when narrow.Thereby zoom position ZP1 can be used as the narrow zoom position of the angle of visual field, for example as the zoom position of the angle of visual field less than 10 degree.Therefore, the predetermined zoom zone of preferentially carrying out zoom through electronic zoom is that the visual field is narrow and easily with the zoom area of losing the side of looking in the distance of being taken the photograph body, and when surpassing this zoom area, for the deterioration of the image quality that prevents photographs, carries out optical zoom.In Fig. 5, solid line is represented the action of electronic zoom.
This zoom operation amount Z1 or zoom operation amount ZP1 are stored in the memory or register in signal processing and the control part 11 in advance.In addition, this zoom operation amount Z1 or zoom operation amount ZP1 also can be changed by the user, and value after changing is stored in the memory or register in signal processing and the control part 11.
CPU receives the focal length information of camera lenses 3 via Department of Communication Force 12,32, and confirms zoom position ZP1 shown in Figure 5 and zoom operation amount Z1 according to the area information that can keep predetermined image quality in the imaging apparatus of image pickup part 14 (perhaps the user is preparing to follow the zoom position information of being taken the photograph body of losing when taking with digital camera 1 easily).Zoom operation amount Z1 is the limit operation amount of electronic zoom, and zoom position ZP1 is the limit zoom position of electronic zoom.
For example; Even if to the camera watch region of imaging apparatus 1/4 till; Use electronic zoom function to take, have the above image quality of predetermined image quality if take the image that obtains, then predetermined zoom position ZP1 is set at the position corresponding with 1/4 of the camera watch region of imaging apparatus.In addition, because this ratio changes according to the pixel count of imaging apparatus, therefore also can be 1/3,1/5 etc.Moreover this ratio also can be according to user's hobby, require level etc. to change.
In addition, in the angle of visual field of the telescope end of optical zoom, also can be arranged to the camera watch region of imaging apparatus to the zone of the angle of visual field wideer (for example can guarantee the zone of the wide visual field angle of about 5 degree) than this angle of visual field.Perhaps, in the angle of visual field of the telescope end of optical zoom, also can for example carry out zoom control for the more wide visual field angle that can guarantee about 10 degree.
Therefore, when the user zooms to when looking in the distance side from the wide-angle side, in the zoom area ZM1 till from maximum wide-angle state (0) to zoom operation amount Z1, carry out zoom through electronic zoom.That is, cut out the image behind the electronic zoom in the image pickup scope IPA that takes by image pickup part 14, and be presented on the display frame 18a of display part 18.
When the zoom operation amount surpassed Z1, the zoom position ZP1 of electronic zoom was fixed, and beginning is based on the optical zoom of the action of the camera lens in the camera lens 3.On the position of zoom operation amount Z1, do not carry out zoom based on optical zoom, when the zoom operation amount surpassed Z1, zoom position increased according to the zoom operation amount.
In Fig. 5, the line shown in the chain-dotted line is represented the action of optical zoom.That is, surpass among the zoom area ZM2 of zoom area ZM1 in the zoom operation amount, electronic zoom is constrained at zoom position ZP1 and fixes, and also can not move even if further carry out zoom operation.On the other hand, in zoom area ZM2, thereby the mode of zoom position increase is changed to carry out optical zoom according to the zoom operation amount.In zoom area ZM2, zoom position is the position behind combination electronic zoom and the optical zoom shown in the dotted line among Fig. 5.
Be presented at image that the image on the display part 18 becomes image pickup scope IPA from the image change of zooming range ZA corresponding to the zoom position that is presented at the image on display part position from the change in location of the some P1 corresponding to the some P2 of the zoom amount of the electronic zoom that descended among Fig. 5 with certain zoom position.
Carry out the control of the actuating range of electronic zoom corresponding and optical zoom with zoom area shown in Figure 5 by the scope control part 11a of signal processing and control part 11.
Next the display image on the display frame 18a that is presented at display part 18 is described.
Fig. 6 is image pickup scope and the figure of zooming range that is used to explain the imaging apparatus of image pickup part 14.In addition, the display control unit 11b of signal processing and control part 11 is shown to the image demonstration of display frame 18a.In Fig. 6, the central portion of image pickup scope IPA, area is about 1/4 part and is expressed as camera coverage limit range or the camera coverage limit area that can keep predetermined image quality.
At this moment, even if optical zoom is to the focal length of about 400mm according to the conversion of 35mm film camera, also can adopt periphery to have about 5 degree field of view angle more than needed.Certainly, if sacrifice image quality, can also be corresponding with longer focal length.Through guaranteeing image quality and field of view angle like this, can be arranged in the digital camera that at once to find to be taken the photograph body when taking the photograph body with losing.
As stated, with losing the surplus capacity of guaranteeing to expand the angle of visual field when taking the photograph body.When electronic zoom began, the image for the image pickup scope IPA of image pickup part 14 shootings cuts out zooming range ZA was presented on the display frame 18a.That is, the image range PA on every side shown in Fig. 6 bend is not presented on the display frame 18a.If shooting push button is promptly pressed in operation, the image of zooming range ZA can be recorded in the recording medium of recording portion 16.And usually, the image of image range PA on every side around the zooming range ZA is not presented on the display frame 18a.
Carry out electronic zoom from image pickup scope IPA to the camera coverage limit range, but in the camera coverage limit range, do not carry out.
But of the back, when detecting user P with losing when being taken the photograph the bird of body, display frame 18a goes up the image (be the image of zooming range ZA and the image of image range PA) on every side of demonstration image pickup scope IPA as assistant images.In other words, image range PA is the demonstration private part of following when losing on every side.
In addition, also can dwindle on every side the image of image range PA (below be called image on every side) PAP, and be presented on the display frame 18a.
Fig. 7 is the figure that the example of the assistant images on the display frame 18a that is presented at display part 18 is shown.As shown in Figure 7, in the image of image pickup scope IPA, the image PAP on every side of image range PA is compressed and dwindles demonstration on every side, and its inboard enlarged and displayed has the zoom image ZAP of zooming range ZA.
Fig. 7 is shown as an example in to show under the state of 2 times of zooms and also comprises the state of the image of image PAP on every side.Illustrate: half of transverse direction of establishing display frame 18a is 1 o'clock, and the length of the transverse direction of image PAP is 1/4 on every side.That is, in order to dwindle image PAP on every side, amplify zoom image ZAP, and these two images are converged among the display frame 18a, promptly, change ratio separately and synthesize the generation assistant images in order to make and display frame 18a big or small consistent or roughly consistent.In other words; When detecting with losing when being taken the photograph body, microfilming is with image PAP around extraneous, and according to the dwindling with extraneous image of photographing; Macrophotography is with the image of scope, and the image that has synthesized this image that dwindles and this enlarged image is presented on the display part 18.The change-detection of operation that can be through the user, action, image go out this quilt take the photograph body with losing.
Even if on every side image PAP dwindled also can be as shown in Figure 7 that kind bird image B I is presented on the display frame 18a, therefore, user P can be known the direction towards the optical axis of camera lens 3.In addition, zoom image ZAP is also to be presented on the display frame 18a with the big ratio of ratio of image range PA on every side than the zooming range ZA among Fig. 6, therefore, and user easier identification photographs.
(processing)
Below the explanation digital camera 1 photography the time processing.Fig. 8 is the flow chart of the example of the handling process the when photography of digital camera 1 is shown.The processing of the CPU execution graph 8 of signal processing and control part 11.The handling procedure of Fig. 8 is stored among the ROM (not shown) in signal processing and the control part 11.In addition, Fig. 8 is that to have set limit zoom position ZP1 be the example of the multiplying power of camera lens 3, be 2 times to multiplying power till the electronic zoom situation of moving.
During the power connection of digital camera 1, CPU judges whether set photograph mode (S1) by the user.When being not photograph mode (S1: not), carry out other mode treatment, for example, the processing of reproduction mode.
When being photograph mode (S1: be), CPU obtains the various data (S2) such as focal length of camera lens 3, and judges whether be auxiliary mode (S3).When being zoom, this auxiliary mode, judges whether digital camera 1 is set for auxiliary mode by the user with losing the above-mentioned pattern of carrying out the auxiliary image demonstration under the situation of body of being taken the photograph.The scheduled operation of the main part 2 through logarithmic code camera 1 carries out the setting of auxiliary mode.The operating portion of main part 2 and operation determination section 20 constitute mode setting part, and this mode setting part is set the auxiliary mode as preassigned pattern.
Do not set at digital camera 1 under the situation of auxiliary mode, CPU judges whether carried out zoom operation (S4).When having carried out zoom operation (S4: be), CPU carries out optical zoom control operation (S5), and carries out region-wide demonstration (S6).Region-wide demonstration is that the region-wide image of taking the image pickup scope IPA that obtains through the imaging apparatus of image pickup part 14 is presented on the display frame 18a of display part 18.(S4: not), CPU carries out region-wide demonstration (S6) when not carrying out zoom operation.
Next, judge whether supress shooting push button (S7), when supressing shooting push button (S7: be), the image (S8) of CPU storage image pickup scope handles turning back to S1.In addition, (S7: not), handle turning back to S1 when not pressing shooting push button.
Be configured at digital camera 1 under the situation of auxiliary mode (S3: be), CPU judges whether carried out zoom operation (S9).In zoom operation, CPU is respectively according to according to regional determined zoom area ZM1 that can keep predetermined image quality in the imaging apparatus of image pickup part 14 and the action that ZM2 controls electronic zoom and optical zoom.
In addition; In zoom operation, the user is altered to the setting of digital camera 1 under the situation of auxiliary mode, in S9 from photograph mode; For zoom operation is carried out continuously, zoom operation is carried out in the position corresponding with the zoom operation amount from the S5 before the setting that is altered to auxiliary mode.
When carrying out zoom operation (S9: be), CPU judges that through zoom operation whether the multiplying power of camera lens 3 is till 2 times (S10), if multiplying power is till 2 times, then carries out and the corresponding electronic zoom of zoom operation amount (S11).The multiplying power of camera lens 3 whether be judgement till 2 times in Fig. 5 corresponding to the whether judgement in the scope of zoom area ZM1 of zoom operation amount.
In addition, enumerated multiplying power here and be 2 times example, but according to the performance of the desired image quality of user, imaging apparatus, the telescope end of optical zoom, multiplying power also can be other value.
When multiplying power surpassed 2 times, CPU is electronic zoom (S12) fixedly, and execution and the corresponding optical zoom control operation of zoom operation amount (S13).Multiplying power surpass 2 times situation in Fig. 5 corresponding to the situation of zoom operation amount in the scope of zoom area ZM2.Carry out the processing of S9～S13 by scope control part 11a.Thereby the processing of S9～S13 constitutes the processing of zoom control part, and it carries out zoom control according to the zoom operation for camera lens 3, makes and in the predetermined zoom zone, carries out electronic zoom, and when exceeding the predetermined zoom zone, carry out optical zoom.
After the processing of S11 and S13, CPU judges whether the user is taken the photograph body (S14) with losing.This decision method is described in the back.
If (S14: not), then CPU does not show the selection area image, promptly shows the image (S15) of zooming range ZA with losing.But when losing (S14: be), CPU carries out region-wide demonstration, and promptly (during being 2 seconds here) shows the image (S16) of image pickup scope IPA during predetermined.In addition, though showing region-wide (image of image pickup scope IPA) when losing here, also can show the image of the scope bigger than zooming range ZA.That is, with losing when being taken the photograph body, the image of the scope bigger than the zooming range ZA in the image pickup scope of imaging apparatus is presented on the display frame 18a of display part 18.
Moreover when losing, CPU can not carry out region-wide demonstration (image of perhaps big than zooming range ZA scope shows) for the time being yet, and expands the viewing area gradually from zooming range ZA.For example, control, with the expansion viewing area according to the action that is judged to be with losing.And, after S15 and S16, handle entering into S7.Carry out the processing of S14～S16 by display control unit 11b.Thereby; The processing of S14～S16 constitutes the processing of display control unit; It is taken the photograph body when losing detecting, and the demonstration of display frame 18a is controlled, and makes that the outer image of zooming range in the image pickup scope of imaging apparatus is presented on the display frame 18a of display part 18.
In addition, in above-mentioned example, for whole replacing camera lenses of being installed, till multiplying power to 2 times, only electronic zoom moves, still, also can be according to the camera lens of being installed, change the multiplying power that electronic zoom only moves.For example, in than the zoom lens of wide-angle and the zoom lens of looking in the distance, the scope that electronic zoom is moved is different.For example, because under the situation of the zoom lens of wide-angle, lower with losing the probability of being taken the photograph body; Therefore; Can be set as that electronic zoom moves till multiplying power is 2 times, because under the situation of the zoom lens of looking in the distance, higher with losing the probability of being taken the photograph body; Therefore, can be set as that electronic zoom moves till multiplying power is 3 times.
In this case, the multiplying power of being judged among the S10 is than different in the zoom lens of wide-angle and the zoom lens of looking in the distance, and in than the zoom lens of wide-angle and the zoom lens of looking in the distance, the level of the image quality that is guaranteed is different.
Fig. 9 is the flow chart of example with the flow process of losing determination processing that the S14 of Fig. 8 is shown.At first; CPU is according to the output of the acceleration transducer of motion detection unit 15; As the vibration of camera or having or not of action, for example judge the action that whether exists on above-below direction or the left and right directions more than or equal to predetermined value, promptly whether there is the action of direction up and down (S21).For example, predetermined value is the present angle of visual field, in S21, when having the above action of the present angle of visual field, is judged to be and has the action of direction up and down.S21 constitutes the processing of the motion detection unit of the action of judging photographic equipment.In addition, though detect the action up and down of camera here, can certainly detect with respect to the rotation of optical axis and the action of incline direction.
Under the situation that does not have the action of direction up and down (S21: not),, for example judge whether the color of the central portion in the image that the imaging apparatus through image pickup part 14 obtains exists variation (S22) as having or not of the variation of the image in the picture.CPU keeps watch on the color of this central portion all the time, for example, judges whether the color of central portion belongs to one of a plurality of form and aspect of predesignating, and the form and aspect under the color of central portion are when changing, and the color that is judged to be central portion exists and changes.Perhaps, for example when the bird that chases the white of flying over sky was taken the photograph body as quilt, when only having taken blue sky with losing bird, the color of central portion was varied to blueness from white, and therefore, in this case, there is variation in the color that is judged to be central portion.S22 constitutes the processing of color change test section, the color change of the central portion of the image of the image pickup scope IPA of its detection imaging apparatus.
In addition, though detect the variation of color here, the also variation of sensed luminance, shape variation, and both variation at least that also can detect color, brightness and shape replaces the variation of color.For example, when the variation of brightness at brightness value the variation more than the predetermined ratio has taken place, be judged to be brightness variation has taken place.About shape variation, calculate characteristic quantity and the supervision all the time that the quilt in the central portion is taken the photograph the shape of body through CPU, when the variation more than the reservation threshold has taken place this characteristic quantity, be judged to be shape variation has taken place.
And, (S22: not),, for example judge whether the user is the zoom operation rapidly (S23) more than the scheduled volume for the zoom operation towards the wide-angle side that operating portion 34 carries out under the situation that the color of central portion does not change as having or not of user's operation.For example, have at camera lens 3 under the situation of zoom ring, when zoom is above around axle rotation 30 degree of camera lens 3, be judged to be existence zoom operation rapidly.Have at camera lens 3 under the situation of ZSW, when pressing ZSW (ZSW has the situation of pressure sensor) more at full tilt or push more than the preset time (for example more than 1 second), be judged to be existence zoom operation rapidly.In addition, this judgement also can be carried out in zoom.
Not that (S23: not), CPU is not judged to be the user and is taken the photograph body (S24) with losing under the situation of zoom operation rapidly at the zoom operation that the user carries out towards the wide-angle side.But during for " being ", CPU is judged to be the user and is taken the photograph body (S25) with losing in S21, S22, S23 any one.
As stated; The variation of the image in the pictures such as variation of the color of vibration that waits camera according to having or not of action up and down or action, central portion or towards the zoom operation rapidly of wide-angle side, for the users' such as setting operation of auxiliary mode operation judges that being taken the photograph following of body loses.
Below in the region-wide demonstration of explanation S16 around image range PA around the example that dwindles method of image PAP.Figure 10 is used to explain the figure of the example that dwindles method of image PAP on every side of image range PA on every side.Carry out the processing of S16 shown in Figure 10 by display control unit 11b.
At first, about CPU, the D1 of Figure 10 illustrate among the image pickup scope IPA of imaging apparatus zooming range ZA and on every side around image range PA.Image range PA is split into 8 region R 1～R8 on every side.In the example of Figure 10, be made as 1/4 of image pickup scope IPA to zooming range ZA.
Shown in the D2 of Figure 10, the cut zone in 4 corners (R1, R3, R6, the zone shown in the R8) dwindles into 1/2 respectively on longitudinal direction and transverse direction.In addition; Cut zone (R2 up and down; Zone shown in the R7) on above-below direction, dwindle into 1/2, on left and right directions, the numerical value (being 1.5 in this example) that obtains according to the length L 1 of the transverse direction of removed combination among the D1 with the length L 2 of the transverse direction of zooming range ZA R1 and R2 amplifies.Moreover, about cut zone (R4, the zone shown in the R5) on above-below direction, zoom into 1.5 times, on left and right directions, dwindle into 1/2.In addition, minification can be the ratio beyond 1/2, for example 1/3 etc., and magnification ratio also can be the ratios beyond 1.5 times that are complementary with this minification, for example 2 times etc.
D3 illustrates and dwindles the state that shows peripheral image PAP as described above.In D3,, therefore shown in D4, amplify zoom image ZAP because zooming range ZA is the size of keeping intact.
Consequently, owing on display frame 18a, show the assistant images shown in D4, therefore, user P can confirm that the quilt in the peripheral image PAP takes the photograph the image of body.
In addition, the method for dwindling of the peripheral image PAP of peripheral image range PA is not limited to above method illustrated in fig. 10.For example, under the situation of above-mentioned Figure 10,, merely amplify and dwindle, still, also can arrive the periphery of peripheral image PAP more, change proportion of deformation more according to predetermined multiplying power in direction up and down.For example, according to the distance of periphery, change is dwindled or the ratio of amplifying etc.That is, also can make photography different with at least one basis of photographing with the distance of the central portion of the image pickup scope IPA of the imaging apparatus of image pickup part 14 with the magnification ratio in the amplification of the image of scope with the minification in the dwindling of extraneous image.
As stated; The camera of this execution mode has the user can confirm that with losing following zooming range outside lose the reply function when being taken the photograph body; And camera according to this execution mode; Can be when preventing the image quality aggravation of photographs, in other words when keeping predetermined image quality, the photography of carrying out being taken the photograph body.
In addition; In the above-described embodiment; Set at digital camera 1 under the situation of auxiliary mode, taken the photograph body when losing, though the zooming range image outward in the image pickup scope of image in the zooming range in the image pickup scope of imaging apparatus and imaging apparatus is presented on the display frame 18a of display part 18 when detecting; But when setting auxiliary mode; Through the setting of user to auxiliary mode, display control unit 11b is the demonstration of may command display frame also, makes that image and the outer image of zooming range in the zooming range is presented on the display frame 18a of display part 18 all the time.Promptly; On the user is presented at display part 18 for image and the image outside the zooming range that makes in the zooming range all the time when auxiliary mode the display frame 18a; When logarithmic code camera 1 is set; Taken the photograph body with losing even if detect, image and the outer image of zooming range in the zooming range are presented on the display frame 18a of display part 18.
In this case, for example, on the display frame 18a of display part 18, show the image pickup scope IPA of the imaging apparatus of image pickup part 14.And,, carry out following processing: surround the image in the zooming range with the frame line in order to distinguish image and the outer image of zooming range in the zooming range; Add top shadow on the image outside zooming range; With colour show in the zooming range image and with the outer image of white and black displays zooming range etc.Consequently, the user can discern coverage.This be bad at being taken the photograph the body framing often with lose the user who is taken the photograph body or use the zoom ratio height and the situation of the zoom that the angle of visual field is narrow under effectively.
In addition; 2 auxiliary modes also can be set; Set at digital camera 1 under the situation of the 1st auxiliary mode; Only taken the photograph body when losing detecting; The outer image of zooming range in the image pickup scope of image and imaging apparatus in the zooming range in the image pickup scope of imaging apparatus is presented on the display frame 18a of display part 18, sets at digital camera 1 under the situation of the 2nd auxiliary mode, display control unit 11b is presented at image in the zooming range and zooming range image outward on the display frame 18a of display part 18 all the time.
(second execution mode)
Second execution mode of the present invention is described below.
(structure)
The camera of second execution mode has and is used for taking " moon " as the moon photograph mode of being taken the photograph body.The structure of illustrated camera is roughly the same in the structure of the camera of second execution mode and first execution mode, therefore, below mainly explain in the camera of second execution mode, with the camera head various structure of first execution mode.
About as " moon " of being taken the photograph body and since deep or light contrast high only be profile portion, therefore, the part beyond the profile portion of moon image can suppress contrast and carry out noise removal process.Promptly; Even if dwindle the part that cuts out from photographed images (promptly zoom) significantly from imaging apparatus; Also can access more beautiful image, therefore, can be called with this execution mode that effectively utilizes electronic zoom is corresponding as " moon " of being taken the photograph body and to be taken the photograph body.
Thereby, owing to dwindle above-mentioned zooming range ZA, and only in the assistant images that shows when losing " moon " around the part of image PAP than broad, therefore, the probability that the user can hold the position of " moon " raises.
Figure 11 is used to explain that user P does not carry out the figure of the state of zoom to camera lens 3.
Shown in figure 11, when user P hand-held digital camera 1 will be taken moon M, on one side user P observes the display frame 18a of display part 18, Yi Bian adjust digital camera 1 camera lens 3 towards.Camera lens 3 does not also have zoom, is not in the state of looking in the distance.
In Figure 11, the frame table of dotted line shows the image pickup scope IPA that is taken by image pickup part 14.Moon image M I is presented at respect to whole image on the display frame 18a shown in the frame of solid line lessly.
Figure 12 is the figure that is used to explain the situation that user P carries out zoom to camera lens 3 and moon M is taken.Shown in figure 12, user P wants to carry out zoom through the optical axis with camera lens 3 towards moon M, and under the state of enlarged and displayed moon image M I on the display frame 18a, presses shooting push button, thereby takes moon M.In Figure 12, the frame table of dotted line shows that user P is just carrying out the zooming range ZA of zoom.
But; As first execution mode is illustrated; Concerning user P, be positioned at the approximate centre of the narrow angle of visual field in order to make moon M, and make moon image M I be presented at that the display frame 18a shown in the frame of solid line goes up and adjustment digital camera 1 towards being very difficult.
Here the size to the shooting face of the size of the moon and imaging apparatus describes.Figure 13 and Figure 14 are the figure of size that is used to explain the picture of the moon on the shooting face that is formed on imaging apparatus.
Shown in figure 13; Because the moon approximately has 30 subangles (being about 0.5 degree) (its 15 half the subangles shown in Figure 13); Therefore; In the image pickup scope IPA of the shooting face 14a of imaging apparatus, occupy 1/3 area as M ' for what make the moon, according to following formula (1) and (2), judgement need convert and have the camera lens of 900 focal length Ft according to 35mm film (vertically 24mm).
Fttan (1/4 degree)=4mm...... formula (1)
Ft=4mm/ (tan (1/4 degree))=900mm...... formula (2)
Because it is large-scale in general being equivalent to the camera lens of 900mm, therefore, only can on the small-sized camera that is easier to hand-held carrying, carry or install the optical zoom of about 300mm.
But; If have the words of the imaging apparatus of 2,000 ten thousand pixels; Even if cut 3 times of zooms of 1/9 of camera picture of the shooting face 14a of image pickup scope IPA; Also can in the image after carrying out this zoom, guarantee the image quality of 2,000,000 pixels, therefore, its image has the image quality that can in HDTV, show.
Figure 14 is used for explaining that the once figure of the situation of shake has taken place the camera lens at 30Omm.Shown in figure 14, when hand held camera is prepared to take, with respect to optical axis C shake has once taken place to be equivalent to; But; If have the angle of visual field of the camera lens of 300mm, even if exist user P in the angle of visual field of 900mm, to follow the situation of losing moon M, if the image of above-mentioned image pickup scope IPA is shown as assistant images; Moon image M I is also contained in the assistant images, so user P can be with losing moon M.
Figure 15 is the figure that is used for explaining the image that is presented at assistant images.Shown in figure 14, under the zoom state of 900mm with losing under the situation of the moon, though the assistant images of the scope of the area E shown in the dotted line is presented on the display frame 18a, assistant images comprises moon image M I outside zooming range ZA.
Figure 16 is the figure for the operation of digital camera that is used to explain this execution mode.The operation that the operating portion 20A of user through logarithmic code camera 1 is scheduled to is for example pressed moon photograph mode and is set operations such as button, makes digital camera 1 set moon photograph mode for.The operating portion 2OA of main part 2 and operation determination section 20 constitute mode setting part, and this mode setting part is set moon photograph mode as predetermined pattern, in moon photograph mode, " moon " are taken as taking the photograph body.
(processing)
Processing when next the moon photograph mode of digital camera 1 is described.Figure 17 is the flow chart of the example of the handling process the when moon photograph mode of digital camera 1 is shown.The CPU of signal processing and control part 11 carries out the processing of Figure 17.The handling procedure of Figure 17 is stored among the ROM (not shown) in signal processing and the control part 11.
In addition, in Figure 17, give identical label, and simplification will be described, omit a part for the processing identical with Fig. 8.In addition, explain that here the position that will be fit to above-mentioned high-definition image (HD) is made as the extreme position of electronic zoom, set the situation of zoom operation amount or zoom position.That is, in Fig. 5, zoom position ZP1 sets the zoom position of suitable high-definition image (HD) for.
When the power connection of digital camera 1, CPU judges whether set photograph mode (S1) by the user.(S1: not), carry out other mode treatment, the for example processing of reproduction mode when being not photograph mode.
When being photograph mode (S1: be), CPU obtains the various data (S2) of camera lens 3, and judges whether be moon photograph mode (S31).Whether this moon photograph mode is set for moon photograph mode by the user according to digital camera 1 and is judged as illustrated in fig. 16.
Do not set at digital camera 1 under the situation of moon photograph mode, CPU carries out the processing from above-mentioned S4 to S8.
Set at digital camera 1 under the situation of moon photograph mode (S31: be), owing to be to take the moon, therefore set focusing position at a distance, CPU judges whether carried out track in (zoom up) operation (S32).Carrying out track in when operation (S32: be), whether CPU judges that the high-definition image (HD) at the central portion of the imaging apparatus of image pickup part 14 is fit to carry out zoom (S33) in the scope of portion.
CPU, carries out and the corresponding electronic zoom of zoom operation amount (S11) when in the scope of the suitable portion of high-definition image (HD), having carried out zoom (S33: be) through zoom operation.Through zoom operation, (S33: not), CPU is electronic zoom (S12) fixedly, and execution and the corresponding optical zoom control operation of zoom operation amount (S13) when carrying out zoom above the scope of the suitable portion of high-definition image (HD).The zoom operation amount surpasses the situation of position ZP1 of high-definition image (HD) limit corresponding to the situation of zoom operation amount in the scope of zoom area ZM2.
Carry out the processing of S32～S13 by scope control part 11a.Thereby the processing of S32～S13 constitutes the processing of zoom control part, and it carries out zoom control according to the zoom operation for camera lens 3, makes and in the predetermined zoom zone, carries out electronic zoom, and when exceeding the predetermined zoom zone, carry out optical zoom.
After the processing of S11 and S13, CPU judges whether the user is taken the photograph body (S14) with losing.This decision method is identical with above-mentioned processing shown in Figure 9.Because the contrast of " moon " is higher, so the processing of the S22 among Fig. 9 (detection that has or not of the color change of central portion is handled) plays a role especially effectively.
Do not have with the words of losing (S14: deny), CPU shows the selection area image, promptly shows the image (S15) of zooming range ZA.But when losing (S14: be), CPU will be presented at the image on the display frame 18a, enlarge the area E of the scope that " moon " do not expose from zooming range ZA, and be presented at display frame 18a and go up (S24).Thereby; The processing of S14～S34 constitutes the processing of display control unit; It is taken the photograph body when losing detecting, and the demonstration of display frame 18a is controlled, and makes that the outer image of zooming range in the image pickup scope of imaging apparatus is presented on the display frame 18a of display part 18.
Though also can be with losing the region-wide demonstration of carrying out image pickup scope IPA under the situation of " moon ",, in this execution mode, cut out the area E of the scope that " moon " do not expose, amplify the image of this area E that cuts out, and be shown as assistant images.Thereby the image of the area E that cuts out comprises all images of " moon ".In addition, the image of the area E that cuts out also can not comprise all images of " moon ", also can comprise a part (for example half the).
In Figure 15, shown in dotted line, cut out the image of the scope E that moon image M I do not expose, be amplified to till the size of display frame 18a, and be shown on the display frame 18a.Carry out the processing of S24 by the display control unit 11b in signal processing and the control part 11.
In image pickup scope IPA, in the area E of the scope of not exposing to " moon ",, therefore, can cut out the scope that moon image M I does not expose from the center of image pickup scope IPA through image processing because the contrast of " moon " and background is higher.
Promptly; With during losing " moon ", the image of the scope E that moon image M I does not expose shows when changing size continuously, therefore; The user can adjust glibly digital camera 1A towards, make the position of " moon " move to the centermost of display frame 18a.
As stated; According to the photographic equipment of this execution mode, " moon " is being carried out under the situation of zoom shot, have the user and can confirm that following zooming range outside lose the reply function when losing " moon "; And camera according to this execution mode; Can be in the image quality aggravation that prevents moon image, in other words when keeping predetermined image quality, the shooting of carrying out being taken the photograph body.
In addition; In the above-described embodiment, set at digital camera 1A under the situation of moon photograph mode, when detect " moon " when losing; Though the image that cuts out the scope E that moon image M I do not expose is amplified to the size of display frame 18a; And be presented on the display frame 18a, but when being configured to moon photograph mode, the setting of carrying out through the user; Display control unit 11b is the demonstration of may command display frame also, makes the image of the scope E that moon image M I does not expose be presented at all the time on the display frame 18a of display part 18.Promptly; The user is presented on the display frame 18a of display part 18 for the image that makes the scope E that moon image M I do not expose when moon photograph mode and logarithmic code camera 1A when setting all the time; Even if detect " moon " with losing, the image of the scope E that moon image M I does not expose is also shown on the display frame 18a of display part 18.
At this moment, show the image of the scope E that moon image M I do not expose on the display frame 18a of display part 18.And the image of the scope E that does not expose for image and the moon image M I that distinguishes in the zooming range uses the frame line to surround the processing of image in the zooming range etc.Consequently, the user can identify coverage.This be bad at being taken the photograph the body framing often with lose the user who is taken the photograph body or use the zoom ratio height and the situation of the camera lens that the angle of visual field is narrow under be effective.
In sum, according to the photographic equipment of above-mentioned two execution modes, can provide a kind of user of having with losing the reply function when taking the photograph body and can when preventing the image quality aggravation of photographs, carrying out being taken the photograph the photographic equipment of the shooting of body.
Particularly according to the picture pick-up device of above-mentioned two execution modes, the user can discern the direction of being taken the photograph body intuitively, in other words towards the direction of digital camera.
The invention is not restricted to above-mentioned execution mode, in the scope that does not change aim of the present invention, can carry out various changes and change etc.
