11. the demonstration of oscillating movement correcting value

Figure 20 illustrates the structure according to the image pick-up device 200 of embodiment of the present invention.

Image pick-up device 200 can show the amount that oscillating movement is proofreaied and correct in the mode that is similar to image pick-up device 100.Image pick-up device 200 involving vibrations amount of exercise calculating sections 92, track calculating section 91, display part 95, loud speaker 97, vibrator 98, CPU 99, oscillation gyroscope instrument 101a and oscillation gyroscope instrument 101b.

Oscillating movement amount calculating section 92 (shaking motion detecting section 15: referring to Fig. 1) calculates the oscillating movement amount, and exports this oscillating movement amount to the display part 95 via display circuit.Track calculating section 91 calculates the track that can not be proofreaied and correct the oscillating movement of proofreading and correct fully by oscillating movement, and exports this position to the display part 95 via display circuit.

CPU 99 determines that whether this oscillating movement amount is greater than predetermined value.If this oscillating movement amount is greater than predetermined value, then the result is determined at least one output in its indicated number part 95, loud speaker 97 and the vibrator 98.

Display part 95 shows and determines the result according to the instruction from CPU 99.Loud speaker 97 produces warning sound according to the instruction from CPU 99.Vibrator is according to the instruction vibration from CPU 99.

Figure 21 illustrates the example of the display part 95 that comprises in the image pick-up device 200.

In display part 95, the oscillating movement amount is shown by indicating device 93,93a, 93b and 93c.By the visual observation display, the people of photographic images can identify oscillating movement amount and vibrational motion.By identification oscillating movement amount and vibrational motion, photographer can change the fixedly method of camera.As a result, can obtain to comprise than usual the still less still image of oscillating movement by people's operation.

Figure 22 illustrates another example of the display part 95 that comprises in the image pick-up device 200.

In display part 95, demonstrate oscillating movement and can not be proofreaied and correct the position of proofreading and correct fully, such as position 94b and position 94d by oscillating movement.By this display of visual observation, the people of photographic images can discern the degree that still image stands oscillating movement after photographic images.The failure that oscillating movement is proofreaied and correct can be determined by little display part on the camera.Therefore, photographer can check the failure that oscillating movement is proofreaied and correct.In film (filming) pattern, (for example, shake and clap or full views watching), just can only check oscillating movement longitudinally.

In display part 95, if (x is y) greater than predetermined value (x for the oscillating movement amount ₀, y ₀) ((x〉x ₀, or y y ₀) or (x〉x ₀, and y y ₀)), then can show warning.In addition, loud speaker can be exported warning sound.For example set predetermined value (x according to zoom ratio ₀, y ₀).

In addition, in display part 95, if (x is y) less than predetermined value (x for the oscillating movement amount ₀, y ₀) ((x＜x ₀, or y＜y ₀) or (x＜x ₀, and y＜y ₀)), then can display message (for example " OK ").In addition, loud speaker can output sound.For example set predetermined value (x according to zoom ratio ₀, y ₀).

Figure 23 illustrates the demonstration of border indicating device 97 when shaking bat mode or panorama mode pictures taken.

Figure 23 (a) illustrates scene to be taken, and this scene is divided into three frames.

Figure 23 (b) illustrates frame 98a.Figure 23 (c) illustrates frame 98b.Figure 23 (d) illustrates frame 98c.Figure 23 (e) illustrates frame 98d.

When the direction of scene to the right that Figure 23 (a) illustrates taken in the panorama mode, sensing point 96a among sensing point 96a, 96b and the 96c (referring to Figure 23 (b)) is moved and is arrived the left end (referring to Figure 23 (c)) of frame 98b in frame, wherein these points are the expression points that are used for the motion vector detection of oscillating movement correction.At this moment, the shaking motion detecting section 15 that is used to survey motion detects screen and is offset L1 to the right, and the border indicating device 97a on frame right-hand member border is presented on the position apart from frame right-hand member L1 (referring to Figure 23 (c)) among indication Figure 23 (b).

Similarly, shaking motion detecting section 15 detects screen and is offset L2 to the right, and border indicating device 97b is presented on the position apart from frame right-hand member L2 (referring to Figure 23 (d)).

Similarly, indicating device 97c in border is presented at the left end of screen among Figure 23 (e).In the case, the people of shooting can know that current location has arrived the next position that will take next image.If desired, can point out this people this audible alert thus from the warning of loud speaker 37 (see figure 1) output sounds.At this moment, by pressing shutter release button, the people of shooting can take the image of almost ideal panorama form.

For a plurality of sensing points are set on screen, and people's the motion of determining photographic images from the motion vector of sensing point is as the motion of frame, thereby described this method.

In the method, shake and clap the shaking motion detecting section execution of surveying by being used to proofread and correct oscillating movement.Yet, as shown in figure 20, in the image pick-up device of surveying oscillating movement, by using oscillation gyroscope instrument 101a and oscillation gyroscope instrument 101b, can also shake the bat anglec of rotation by what the oscillation gyroscope instrument was surveyed photographer, and obtain to clap required anglec of rotation θ laterally shaking for a frame according to the zoom ratio of zoom probe portion ₀

In the state that Figure 23 (b) illustrates, show border indicating device 97 at right-hand member.Under this state, first two field picture in photographer's photographing panorama picture.Below, pass through anglec of rotation θ photographer in direction to the right ₀Carry out camera shake bats (that is, rotating) time, photographer can know the current location of camera arrived this photographer can photographing panorama picture in the position of second two field picture.

When the anglec of rotation arrives anglec of rotation θ ₀The time, border indicating device 97c is presented at left end (referring to Figure 23 (e)).At this moment, arrive anglec of rotation θ via the loud speaker or the display prompts photographer anglec of rotation ₀Press the result of shutter release button at this moment as photographer, just can obtain at horizontal panoramic picture accurately.

By border indicating device 99a and the 99b on the vertical direction that shows on the display part 12 except laterally, just can be so that photographer's acquisition panoramic picture (referring to Figure 23 (b)) accurately all on both direction easily.In the case, shake the bat direction accurately by using the arrow demonstration on the display screen, photographer just can only guide camera on the direction that arrow is pointed out, thus the image of the pattern that pans easily.In a word, because photographer's hand held camera in photographic images, this photographer can not accurately determine the direction of image taking.Yet, by using the oscillating movement calibration function of camera, adjust left and right, the upper and lower end of screen automatically, just can be very accurately with panorama mode photographic images.

Even when left and right, the upper and lower end of screen uses the oscillating movement calibration function of camera self-adjusting, between the panorama scene of actual acquisition and the most desirable panorama scene that can collect, can make a mistake.By extra with this error logging in the attribute data (Exif etc.) of the status attribute of expression photographic images, just can when a plurality of images are synthesized single panoramic picture, aim at left and right, the upper and lower end of screen more exactly.This is because can revise mistake according to error message.

Above-described function can also realize when the oscillating movement detection method is the electron detection method in a similar manner.

Figure 24 is illustrated in the sensing point of surveying oscillating movement in the frame.Oscillating movement survey often failure or frame per second lower in, can be by changing the position separately of sensing points 96 in the frame 98, or increase the number of sensing points 96 in the frame 98, thus increase the success rate that oscillating movement is surveyed.

Therefore, according to image pick-up device of the present invention, the people of photographic images can discern the degree of oscillating movement.By the degree of identification oscillating movement, photographer can change the method for fixed camera.As a result, can obtain a kind of like this still image, its oscillating movement that has is less than usually by the viewed oscillating movement of people's operation.

As mentioned above, be in the chapters and sections of (demonstrations of 11. oscillating movement amounts) at exercise question, see figures.1.and.2 and 0 to 23 described illustrative embodiments of the present invention.

For example, in the execution mode shown in Fig. 1 and Figure 20 to 23, shaking motion detecting section 15 (oscillating movement amount calculating section 92) is corresponding to " being used to survey the oscillating movement amount probe portion of the oscillating movement amount between the multiframe of the still image that expression takes ", CPU 99 is corresponding to " being used for determining that the oscillating movement amount is whether greater than the determining section of predetermined value ", and display part 95, loud speaker 97 and vibrator 98 are corresponding to " result's output is determined in output ".

Yet image pick-up device of the present invention is not limited to the execution mode shown in Fig. 1 and Figure 20 to 23.Each parts that comprises in the image pick-up device can have arbitrary structures, as long as this image pick-up device has following each function: " being used to survey the oscillating movement amount probe portion of the oscillating movement amount between the multiframe of the still image that expression takes ", " being used for determining that the oscillating movement amount is whether greater than the determining section of predetermined value " and " the definite result's of output output ".

12. the operation of track calculating section

The operation of track calculating section 91 of the present invention will be discussed in more detail below with reference to Figure 25.

Hand moves the oscillating movement of the image pick-up device (camera) 1 that causes and surveys by for example angular velocity detection part 101a and 101b.The oscillating movement detectable signal of the oscillating movement of angular

velocity detection part

101a and 101b output presentation video pick device 1.

Angular

velocity detection part

101a and 101b for example can be angular-rate sensors.This angular-rate sensor for example can be the oscillating movement gyroscope that has a plurality of vibration frequencies that differ from one another respectively.

The oscillating movement detectable signal of angular

velocity detection part

101a and 101b output produces the sample frequency f that part 104 produces with sample frequency _sSample by sample circuit 102.As a result, the analogue data of expression angular speed is converted into numerical data.

Therefore, angular

velocity detection part

101a and 101b are used for the oscillating movement of detection image pick device 1 as shaking motion detecting section, and are used to export the oscillating movement detectable signal of the oscillating movement of presentation video pick device 1.Yet should be noted that angular

velocity detection part

101a and 101b only are the examples of shaking motion detecting section.Shaking motion detecting section can have any configuration, as long as its function that has the function of detection image pick device 1 oscillating movement and export the oscillating movement detectable signal of presentation video pick device 1 oscillating movement.

Track calculating section 91 obtains the trace information of the oscillating movement track of presentation video pick device 1 at least based on the oscillating movement detectable signal of shaking motion detecting section (for example angular

velocity detection part

101a and 101b) output.For example, this track calculating section 91 can obtain to represent the information of predetermined period of time internal vibration movement detection signal change, as trace information.For example, comprise in shaking motion detecting section under the situation of angular-rate sensor, track calculating section 91 can obtain angle information by the output of angular integral velocity transducer, and can obtain to represent the information of angle information change in the predetermined period of time, as trace information.

Oscillating movement correction portion 115 is as electronic vibration motion correction part, be used for image pickup part 5 is exported and is stored in the image information and the trace information execution computing of video memory 120, thereby obtained to have stood the correcting image information that oscillating movement is proofreaied and correct.

Replace electronic vibration motion correction part, a kind of mechanical oscillation motion correction part can also be provided, be used for coming the mechanically oscillating movement of correcting image pick device 1 according to the oscillating movement detectable signal of shaking motion detecting section (for example angular

velocity detection part

101a and 101b) output, thereby obtain the image information of correction, the image information of this correction has stood to proofread and correct by the oscillating movement of actual vibration motion correction amount.In this case, this track calculating section 91 obtains for example to represent the information of the variation of difference between interior this oscillating movement detectable signal of predetermined period of time and this actual vibration motion correction amount, as trace information.

Perhaps, except mechanical oscillation motion correction part, a kind of electronic vibration motion correction part can also be provided, wherein this mechanical oscillation motion correction partly obtains the first correcting image information, this information has stood by the correction of the first oscillating movement correcting value to oscillating movement in the image information, this electronic vibration motion correction partly obtains the second correcting image information, and this information has stood by the correction of the second oscillating movement correcting value to oscillating movement in the first correcting image information.In this case, for example track calculating section 91 obtains the information that the residual vibration amount of exercise changes in the expression predetermined amount of time, and as trace information, this residual vibration amount of exercise is represented the difference between the actual vibration motion correction amount and the first oscillating movement correcting value.

Can be on single semiconductor chip integrated Figure 25 and Figure 30 to the part configuration or the whole configuration of image pick-up device 1 shown in Figure 33.For example, can also go up integrated track calculating section 91, oscillating movement correction portion 115 (electronic vibration motion correction part) and oscillating movement correction control part at single semiconductor chip (semiconductor integrated circuit) and divide in 141 (the mechanical oscillation motion correction parts) at least one.

12.1 optional sampling and compression

Figure 26 (a) illustrates such a case, wherein with the normal time interval (that is predetermined sampling frequency f, uniformly _s) obtain whole samples.Big or at the camera oscillating movement in the bigger time period when the zoom ratio of zoom part 6, in the i.e. time period that temporal change amount is bigger in the output valve of angular

velocity detection part

101a and 101b, shown in Figure 26 (b)

mid point

103a and 103b, with the doubled frequency of sample frequency, promptly with 2f _sCarry out sampling processing more subtly.On the contrary, shown in a 103c and 103d, change amount in time is in less time period, with half frequency of sample frequency, promptly with f _s/ 2 carry out sampling processing more roughly.In the normal time period, shown in a 103e, use frequency f _sMode with standard is carried out sampling processing.

Shown in Figure 26 (b), the sample frequency that sample frequency produces part 104 generations has much the change according to zoom ratio, angular speed amount or angular speed change amount.Dispose with this, can carry out optional sampling.As a result, can obtain the track oscillating movement and proofread and correct required track data, and need not increase amount of information.Under situation about track data 113 being recorded on the exterior storage medium 105, can be so that the data quantity stored minimum.In addition, there is no need increases sample frequency for the whole time period, has just reduced power consumption thus.

For another kind of method, inter-process by track calculating section 91, can sample frequency be set to maximum speed, and measure the combine digital conversion by the detection of sampling oscillating movement, wherein the quantity of sample can increase or reduce according to the change amount of oscillating movement.With the method, just can compress track data.

12.2 interpolation image picking information

The track data of image compression part 105 compression track calculating sections 91 outputs.This compression method is the same with above-mentioned compression method.Image picking information adds part 106 presentation video is picked up the data of the file format of information, such as Exif data 107, adds in the track data that data compression part 105 compressed.Dateout produces part 110 and produces dateout by the data of adding 106 outputs of image picking information interpolation part to image P or view data P ', this image P stands this oscillating movement and proofreaies and correct, from 108 outputs of correcting image output, this view data P ' does not live through oscillating movement and proofreaies and correct, directly from switch sections 109 outputs.

Oscillating movement measurement amount part 111 measuring vibrations amounts of exercise also produce control signal, come according to the oscillating movement amount diverter switch part of measuring 109.Track calculating section 91 comprises treating capacity calculating section 116, is used for calculating the treating capacity of oscillating movement correction portion 115 and is used for producing according to the treating capacity of calculating the control signal of diverter switch part 109.

According to from the control signal of oscillating movement measurement amount part 111 with from the control signal for the treatment of capacity calculating section 116 at least one, switch sections 109 switches producing the part 110 from image pickup part 5 output image datas to oscillating movement correction portion 115 with from image pickup part 5 output image datas to dateout.

Under the situation of oscillating movement amount that oscillating movement measure portion 111 is measured greater than scheduled volume, oscillating movement measurement amount part 111 diverter switch parts 109, make and walk around oscillating movement correction portion 115, directly output to dateout and produce part 110 from the view data of image pickup part 5.For example, treating capacity in the oscillating movement correction portion 115 that treating capacity calculating section 116 calculates greater than the situation of predetermined process amount under (promptly, treating capacity surpasses under the situation of disposal ability of oscillating movement correction portion 115 in oscillating movement correction portion 115), these treating capacity calculating section 116 diverter switch parts 109, make and walk around oscillating movement correction portion 115, directly output to dateout and produce part 110 from the view data of image pickup part 5.In the case, dateout by the data of adding image picking information and adding part 106 outputs (for example produces part 110, Exif data 107, it comprises the track data 113 that is used for oscillating movement, such as point spread function (PSF) etc.) to image P ', produce dateout, wherein image P ' does not stand the oscillating movement correction and exports from switch sections 109.

Output in view data under the situation of oscillating movement correction portion 115 from image pickup part 5, dateout by the data of adding image picking information and adding part 106 outputs (for example produces part 110, Exif data 107, its involving vibrations motion trace data 113, such as point spread function (PSF) etc.) to image P, produce dateout, wherein image P stands the oscillating movement correction and exports from correcting image output 108.

By the dateout output, dateout is recorded on the exterior storage medium 114.The view data of record and can handle in personal computer for the track data 113 of oscillating movement, this computer installation and have higher disposal ability outside camera 1.As a result, in addition view data have bigger vibration amount of exercise and treatment for correcting amount bigger in, also can carry out the reprocessing (post-pocessing) of oscillating movement treatment for correcting.

The operation of image pick-up device (camera) 1 is described with reference to Figure 25.

The light that incides camera 1 passes lens component 2, zoom part 2a and assemblying part 2b, thereby forms image on image pickup part 5.When pressing shutter release button 119, shutter 117 is opened periodic Control part 118 Temporarily Closeds by shutter, and handles at image pickup subsequently and open once more at first.When finishing exposure, shutter 117 is closed once more.When obtaining image pickup data, shutter is opened once more.Image pickup data is stored in the video memory 120 temporarily.Switch sections 109 switches according to above-mentioned execution.

Suppose that the limited disposal ability of camera is expressed as h ₁, and the limited disposal ability of data processing method is expressed as h ₂H satisfies h in the oscillating movement amount ₁＜h＜h ₂Situation under, the oscillating movement correction portion 115 that comprises in the camera can not be handled these data.Therefore, data are directly sent to dateout and produce part 110.Satisfying h ₂Under the situation of＜h, even when using high-speed CPU, can not proofread and correct this oscillating movement.Therefore, view data is sent to dateout produce part 110, and will represent the warning sound of " photographic images once more " or warn demonstration to send to loud speaker 37 or send to display part 12 from caveat section 145.Therefore, just can by the operator once more photographic images reduce because the failure that causes of oscillating movement.

Oscillating movement recoverable amount is by h ₁Expression.Satisfying h ₁Under the situation of＜h, can in camera, carry out treatment for correcting.Therefore, view data is sent to oscillating movement correction portion 115.In oscillating movement correction portion 115, use is for the weighting track data 113 of oscillating movement and the image P ' of oscillating movement is wherein arranged, the result of the inverse-Fourier transform of carrying out as inverse-Fourier transform part 121 and obtained to stand the image P that oscillating movement is proofreaied and correct.

Maximum vibration amount of exercise calculating section 163 calculates maximum vibration amount of exercise x on the x direction based on the image 112,112a and the 112b that pick up ₁And x ₂, and maximum vibration amount of exercise y on the y direction ₁And y ₂(referring to Figure 27 (b)).

Prune part 123 based on maximum vibration amount of exercise x on the x direction ₁And x ₂, and maximum vibration amount of exercise y on the y direction ₁And y ₂, by with x ₁, x ₂, y ₁And y ₂Size prune peripheral part of captured image 112, produce the image 129 (referring to Figure 27 (c)) of pruning.Number of pixels in the image of pruning 129 is less than the number of pixels in the captured image 112.

Enlarged 122 is carried out to enlarge and is handled, thereby image augmentation is arrived intended pixel number (Figure 27 (d)).

The center 126a of the original image 112 shown in Figure 27 (a) is not consistent with the center 126 of the image of pruning shown in Figure 27 (c) 129.In example shown in Figure 27 (c), with off-centring (x ₃, y ₃).Be provided with under the situation of switch with the center 126a of selection original image 112 the operator, the image of pruning 129 is converted into trimmed image 129a (Figure 27 (e)), makes that the center 126a of original image 112 shown in Figure 27 (a) is consistent with the center 126a of trimmed image 129a shown in Figure 27 (e).Trimmed image 129a shown in Figure 27 (e) is extended, thereby becomes the output image 147 shown in Figure 27 (d).As a result, the correcting image of acquisition has the center 126b consistent with the center 126a of original image 112.

The image that stands the oscillating movement correction in this way is sent to dateout through correcting image output 108 and produces part 110.Also send it to switch sections 124.

Switch sections 124 outputs to dwindle part 125 and will output to dwindle between the part 125 from image P 108 outputs of correcting image output, that stood the oscillating movement correction at the image P ' that will not stand the oscillating movement correction and switches.

Dwindle part 125 by reducing to come downscaled images P ' or image P, and on display part 12, show image P ' that dwindles or the image P that dwindles from the image P ' of switch sections 124 outputs or the number of pixels of image P.Can show the oscillating movement track that track display part 126 produces in such a way, make on display part 12 that promptly track and image P ' or image P are overlapping.

For example, the operation of switch sections 124 makes and show the image P ' that dwindles immediately after images acquired on display part 12, and after having gathered image and having finished the oscillating movement correction,, on display part 12, show the image P that dwindles through in the predetermined amount of time.Dispose with this, just can be so that the operator watches the image of collection immediately after images acquired.Do not have this switching, just make the operator at the image that when finishing the oscillating movement correction, cannot watch collection during the several seconds.

12.3 the method for display image

The process of display image is described with reference to Figure 28 and 29.

In step 127, show n width of cloth image.In step 127a, gather n width of cloth image.In step 127b, treating capacity calculating section 116 calculates carries out the required time t of oscillating movement correction calculation _pAt t _pSurpass expression and handle under the situation of feasible fiducial value, handle advancing to step 127c, wherein the warning of issue expression " photographic images once more ".In step 127a, the operator is photographic images once more, and processing advances to step 127b.When the oscillating movement amount is less than or equal to the value that is limited, handle advancing to step 127d.At the images acquired display switch is under the situation of ON, and this processing advances to step 127k, and the track 129 of images acquired before wherein oscillating movement being proofreaied and correct and the oscillating movement that takes place during the images acquired time period is presented on the display part 12.At this moment, also show treatment state indicating device 130.Be expressed as t by full scale (full scale) with treatment state indicating device 130 _f, 130 demonstrations of treatment state indicating device begin elapsed time section, wherein t from treatment for correcting _fBe that the cycle is handled in the estimation that treating capacity calculating section 116 obtains.After handling beginning, show immediately as the treatment state indicating device of reference marker 130 expressions, and in, shown in reference marker 130a and display indicator near the processing end.Therefore, just can know how long to finish processing for the user.Dispose with this, can satisfy user's hope, promptly the user wants to know up to processing how long need to finish.

In step 127m, when having finished the oscillating movement correction, among the step 127n, by switch sections shown in Figure 25 124, the image P ' that proofreaies and correct through oscillating movement is not switched and has become to stand the image P that oscillating movement is proofreaied and correct, and shows the image that switches on display part 12.

At step 127e, be under the situation of OFF at oscillating movement track display switch, will show image at step 127f with oscillating movement.In the case, do not show the oscillating movement track.Step 127g is the same with 127h with above-mentioned steps 127m and 127n, and therefore with the descriptions thereof are omitted.In step 127i, dwindle from the reduced part 125 of image of image pickup part, and on display part 12, show the image that dwindles.In step 127j, image pick-up device is ready to gather next image.

Referring back to step 127d, is under the situation of OFF gathering the screen display switch, handles the step 128a that advances among Figure 29.In step 128a, display image picks up the n width of cloth image in the part.In step 128b, when pressing shutter release button, images acquired.At step 128c, begin the correction of oscillating movement in the n width of cloth image.At step 128d, the mark 131a of expression " oscillating movement is proofreaied and correct and is performed in the n width of cloth image " is presented on the display screen 132j.In step 128e, (n+1) width of cloth image is presented on the display screen 132j in the image pickup part, and shows treatment state indicating device 130b.In step 128f, when oscillating movement is proofreaied and correct and gathered (n+1) width of cloth image under the still uncompleted situation in n width of cloth image, in step 128g, whether also has available space with regard to check image memory 120.Do not have in video memory 120 under the situation of free space, show the mark 133 of expression " wait " in step 128h, shown in display screen 132k, thereby the user stops to gather down piece image.Have in the video memory 120 in step 128g under the situation of free space, handle and advance to step 128j, wherein the track data of oscillating movement is stored in the video memory 120.In step 128k, show mark 131b and (n+2) width of cloth image of expression " correction of oscillating movement is being performed in (n+1) width of cloth image ", shown in display screen 132m.In step 128m, when finishing for the treatment for correcting of n width of cloth image, in step 128n, the mark 131a of expression " oscillating movement of n width of cloth image is proofreaied and correct and is being performed " is eliminated shown in display screen 132n.In step 128p, when finishing for the treatment for correcting of (n+1) width of cloth image, in step 128q, the mark 131b of expression " oscillating movement of (n+1) width of cloth image is proofreaied and correct and is performed " is eliminated shown in display screen 132p.Subsequently, image pick-up device is ready to gather (n+2) width of cloth image.

In order to make oscillating movement correction portion 115 shown in Figure 25 suitably carry out treatment for correcting, the trace information that importantly is used for oscillating movement should be accurate.By the path of tracing path data, from such as the data of the angular velocity detection part 101a of oscillation gyroscope instrument and 101b by integrator 136 integrations, thereby obtain integration angle θ.Obtain zoom ratio information from zoom part 6, and obtain focus data from converging adjustment member 137.Calculate focal distance f, and obtain f * tan θ, and carry out track and calculate.As described in reference Figure 26 (b), can change number of samples by variation according to angle θ, accurately obtain data.Most preferably convert trace information to function.

In oscillating movement correction portion 115, be applied on the function that lopcus function execution inverse-Fourier transform is obtained by the image P ' that will have oscillating movement, just use this track data to obtain the original image P that proofreaies and correct.This calculating can use two dimensional filter 135 to carry out.According to method of the present invention, just can obtain the track data of oscillating movement exactly by using oscillation gyroscope instrument etc.As a result, just can accurately proofread and correct oscillating movement.When not camera 1 in, not carrying out oscillating movement and proofreading and correct, the view data that the image data of adding to by the trace information to oscillating movement such as the Exif data obtains is exported.As shown in figure 35, the assembly 152 of camera 1 comprises image pick-up device 1 and such as the recording medium 151 of CD-ROM.Oscillating movement treatment for correcting program 153 is recorded in the recording medium 151.The user is installed to recording medium 151 in the computer 150, makes the treatment for correcting program be installed to computer 150 from recording medium 151.From the Exif data of camera 1 acquisition acquisition of image data and involving vibrations motion track information, make and calculate these data to proofread and correct in the oscillating movement.Should be noted that in the case the form of IMAQ information is not limited to the Exif form.Can realize similar effects by the form that uses any other IMAQ information.

Estimate the required time cycle of oscillating movement correction by treating capacity calculating section 116.Therefore, can pre-determine whether can in camera itself, carry out this processing.As a result, can on the display part, show the time that treatment for correcting is required, and, improve for users' interfaces by showing the degree of processing progress.

The track of residual vibration campaign after 12.4 oscillating movement is proofreaied and correct

With reference to Figure 30, will be described in and comprise along two axles (for example, x axle and y axle) and carrying out in the camera of oscillating movement correction portion of optical correction processing etc., after proofreading and correct, exports oscillating movement method such as the residual vibration campaign of Exif data.

According to the oscillating movement data of surveying in Figure 30, the oscillating movement correction control part divides 141 output oscillating movement correction signals.Lens driving section 140 drives correcting lens 2c in x direction and y direction, thereby proofreaies and correct oscillating movement.

In fact, this control system has frequency response characteristic.Therefore, do not proofread and correct oscillating movement fully, and oscillating movement correction back residual vibration campaign exists also.In addition, when using known optical bearing calibration or known CCD driving method, can only on x direction and y direction, carry out and proofread and correct, and cannot go up to carry out in z direction (sidewindering direction) and proofread and correct.For the residual vibration campaign behind the calculation correction oscillating movement, just require oscillating movement correcting value calculating section 142 to obtain actual correcting value, and subsequently actual correcting value is input to difference part 143a and the 143b that comprises in the difference part 143 from lens driving section 140.This angular velocity detection part 101 comprises the angular velocity detection part 101c for z direction (sidewindering direction).The component of the x direction that angular velocity detection part 101 obtains and the component of y direction are input to difference part 143.

For x direction and y direction, oscillating movement is proofreaied and correct the remaining oscillating movement in back and can be used expression formula " (actual vibration amount of exercise)-(actual vibration motion correction amount)=oscillating movement is proofreaied and correct back residual vibration campaign " to calculate.By the residual vibration campaign of x and y direction and the angle information of z direction are input to track calculating section 144, just obtained the trace information of residual vibration campaign on x and the y direction.Be integrated and calculated difference not from the data of the angular velocity detection part 101c of z direction, and send it to track calculating section 91, thereby obtain trace information.This trace information 113 shows on display part 12 in such a way, promptly makes trace information 113 cover on the image of collection.Simultaneously, trace information is sent to data compression part 105, thereby with data compression.Add part 106 by image picking information and add the data of compression to view data, to produce dateout as Exif data 107.By data output unit 146, the dateout of generation is recorded on the exterior storage medium 114 such as IC-card.

The Exif data comprise the trace information of oscillating movement on residual vibration campaign after oscillating movement on x and the y direction is proofreaied and correct and the z direction.Therefore, using trace information 113, view data and trace information, carry out inverse-Fourier transform by computer, can be to proofread and correct oscillating movement by data processing on x, y and z (deflection, pitching and the sidewinder) axle on three directions.In optical correction is handled, present frequency response characteristic.Oscillating movement is not clearly under the situation of normal picture size, but just apparent in view in large-sized image.According to the reprocessing of said method, almost can proofread and correct oscillating movement fully.This is very significant effect.

When semi-conductive disposal ability uprises, just can implement oscillating movement on y and the z direction and proofread and correct by the software in the camera 1 at x.Yet owing to need higher computing ability, therefore temporary transient the execution in camera proofreaied and correct also unrealistic to the oscillating movement of three axles.Along with time course, can consider the method that some are feasible.First method is included in the track data x that calculates oscillating movement in the camera, y and z and with track data as the output of Exif file, make and externally carry out treatment for correcting (referring to Figure 30) in the computer by data processing.Second method is included in the camera of the function with calibrating optical oscillating movement, use the oscillating movement correction control part to divide 141 to carry out the optical correction processing in the x and y direction, by the track data that uses track calculating section 144 to calculate in the z directions (sidewindering direction), and track data is attached to (referring to Figure 31) on the view data as Exif data 107.Consider in the z direction and carry out the difficulty that optical correction is handled, carry out oscillating movement by software in the outer computer in the z direction and proofread and correct that the oscillating movement that just can carry out the z direction is proofreaied and correct and do not increased the quantity of camera part.Therefore, just can carry out oscillating movement along three all axles proofreaies and correct.

Third party's method is included in x and the y direction is carried out the optical correction processing, by using track calculating section 144, data based on angular velocity detection part 101c output, calculate the track data of z direction (sidewindering direction), proofread and correct by the oscillating movement that uses oscillating movement correction portion 115 to carry out on the z direction, wherein oscillating movement correction portion 115 comprises inverse-Fourier transform part 121 or Fourier transform part, thereby with the data record that obtains externally (referring to Figure 32) on the storage medium 114.The use of inverse-Fourier transform part has been described in this manual.Yet, much less, can obtain similar effects by using the Fourier transform part.Owing to enlarge by zoom, so the oscillating movement of x and y direction can cause strong motion.On the contrary, the oscillating movement on the z direction (sidewindering direction) causes the motion of easing up and more stable.Therefore, can have the CPU of lower reason ability, on the z direction, carry out oscillating movement and proofread and correct by use.For the third method, the correction of only carrying out z direction oscillating movement by data processing is real.

The 4th kind of method is included in to be carried out optical correction and handles on x and the y direction, the track data of the residual vibration campaign that calculating can not be proofreaied and correct, and track data is added to as the Exif data in the image of collection (referring to Figure 30).In this case, the oscillating movement component in the high frequency band is handled by optical correction and is eliminated, and oscillating movement is proofreaied and correct the track data of back residual vibration campaign only corresponding to oscillating movement component in the lower band.As a result, just can more easily carry out the correction of oscillating movement by computing.

The 5th kind of method proofreaied and correct (referring to Figure 25) about carry out all oscillating movements by the data processing in the camera.Yet, can not proofread and correct violent oscillating movement by data processing.Therefore, preferably by using the oscillating movement correction control part to divide 141 in x and y direction, to carry out optical correction processing etc., calculate remaining oscillating movement with reference to the described mode of Figure 30 by usage variance part 143 with above being similar to, by using track calculating section 91 to calculate the track data of residual vibration campaign, by using oscillating movement correction portion 115, use track data and stood the view data that the optical correction in x and the y direction is handled, proofread and correct x, the oscillating movement (referring to Figure 33) in y and the z direction by data processing.As a result, can carry out oscillating movement in camera on all three axles proofreaies and correct.According to the method, just eliminated the component of oscillating movement in the high frequency band by the optical correction processing.As a result, just can more easily carry out the correction of residual vibration campaign by data processing.In addition, just can realize the correction of oscillating movement in the z direction (sidewindering direction), and be difficult to realize above-mentioned correction by using optical correction to handle.

Here, proofread and correct the calculating that oscillating movement is proofreaied and correct with describing.As shown in figure 34, suppose to represent original image, represent the gesture function of the trace information of oscillating movement with h with i.Stood the image i ' of oscillating movement, represented (that is i*h=i ') with i convolution h.When Fourier transform is used for each, obtain I * H=I '.Therefore, I=I '/H is defined as C.When inverse-Fourier transform was used for each, i equaled inverse-Fourier transform (C), and i also equal inverse-Fourier transform (I '/H) (referring to expression formula shown in Figure 34 (4)).Because i equals i ' convolution (inverse-Fourier transform (I/H)) (that is, i=i ' * (inverse-Fourier transform (I/H))), supposes that inverse-Fourier transform (I/H) is defined as h ', just obtains i=i ' convolution h ' (that is i=i ' * h ').In this calculating of each execution, just need the long period to carry out calculating, and the difficult following image of gathering that becomes.This is because for example the disposal ability of the calculator that comprises of the image pick-up device that is used for rest image of digital camera is lower.For fear of the image that becomes below gathering, just provide video memory 120.The image sequence of gathering is input in the video memory 120, has wherein stored several images acquired.Yet preferably this operator's long period can not checked the image of collection for the operator.In order to address this problem, as described in top execution mode, in images acquired, the images acquired that will not stand the oscillating movement correction is presented on the display part 12.This just makes the operator can check the image of collection roughly.When after showing images acquired, having passed through the scheduled time, especially when having finished the oscillating movement correction calculation, will be presented on the display part 12 through the correcting image that oscillating movement is proofreaied and correct.Therefore, just can be so that the operator check the image that the n width of cloth is gathered immediately after gathering n width of cloth image, and just can check the n width of cloth image of the correction of passing through the oscillating movement correction subsequently.Therefore, the operator can not be subjected to anyly to check the image of collection by vision in seamless mode with interrupting.Before the calculating of n width of cloth image rectification is finished, gather under the situation of (n+1) width of cloth image and image after this, (n+1) width of cloth image and image are afterwards stored in the video memory 120, shown in Figure 25 waits, and (n+1) width of cloth image that will gather recently and the demonstration one by one on the display part of image afterwards.

Here, shorten the method for calculating required time of carrying out with describing.Shown in the expression formula (3) and (4) of Figure 34, the calculating that needs Fourier transform is to rebuild original image.Yet,, need greatly increase computational speed in order in digital camera, to carry out the calculating of Fourier transform.May need a lot of years could realize this CPU.Reason shown in the expression formula (6) of Figure 34, is prepared inverse-Fourier transform h ' in advance for this reason, and wherein inverse-Fourier transform h ' is Fourier transform H contrary of PSF (point spread function) h, and wherein PSF h is the weighting track of trace information.This h ' selects according to oscillating movement.In calculating section 148, carry out h ' and stand the convolution of the image i ' of oscillating movement, thus acquisition original image i.By preparing h ' in advance, just can reduce the required time of computing.Therefore, counting circuit can be merged in the image pick-up device.

Here, will method that survey the oscillating movement correcting value be described.Shown in Figure 36 (a), drive oscillating movement correcting lens 155 by CD-ROM drive motor 156.Hall element 158 is set as lens position probe portion 157 near oscillating movement correcting lens 155, the feasible position of magnetically surveying oscillating movement correcting lens 155, and obtain oscillating movement correcting value 159 subsequently.As another kind of method, shown in Figure 36 (b), calculate the control frequency characteristic 160 or the transfer function 161 of oscillating movement correction portion in advance.By to this system's inputted vibration amount of exercise, just can calculate oscillating movement correcting value 162 by the mode of electricity.In the case, owing to can calculate the oscillating movement correcting value by only using circuit, and do not use mechanical system, so can reduce cost and simplify configuration.

A plurality of oscillation gyroscope instrument are being used to survey under the situation of oscillating movement, and preferably the frequency band by the oscillating movement correcting feature is separated from each other the frequency of each oscillation gyroscope instrument.In the case, can more stably survey oscillating movement.

To the advantage of the use of assembly 152 shown in Figure 35 be described.Carrying out by data processing under the situation of oscillating movement correction, change the lopcus function of oscillating movement for each lens of camera.Therefore, H and h ' shown in Figure 34 change.For first method, can export H and h ' as the Exif data with images acquired from camera.The method has the certainty of higher degree, but the amount that appends to the Exif data on each image is bigger, and comprises a lot of wastes.For second method, for each camera specific, be recorded on the recording medium 151 about the information H and the h ' of lopcus function, this recording medium and camera are fitted together.In the case, can will record on the outer computer for each camera specific trace information H and h '.Therefore, when computer is carried out the oscillating movement correction, just can unsuccessfully not carry out optimum oscillating movement and proofread and correct.

As mentioned above, the present invention comes illustration by using preferred implementation.Yet the present invention should only not explain based on above-mentioned execution mode.Should be appreciated that scope of the present invention should only be explained based on claim.Be further appreciated that those skilled in the art based on the knowledge of describing from the detailed preferred implementation of the present invention with to explanation of the present invention, can realize the equal scope of technology.In addition, be appreciated that any patent of quoting in this specification, any patent application and any document, should by with the mode combination by reference in this manual of specifically described content is the same in specification mode.
