The optical aberration correcting method of digital camera provided by the present invention then is described.Fig. 3 is applied to the optical aberration correcting method flow diagram of digital camera for the present invention.As shown in Figures 2 and 3, the optical aberration correcting method of the digital camera of present embodiment comprises the following steps: at first, use 210 projections of a slice optical mirror slip to wait to take the photograph the light (step S310) of thing, these optical mirror slips 210 can be spheric glass or aspherical lens, and light is through these optical mirror slips 210 and at focus place focal imaging.Then, photo-sensitive cell 230 is in pairing first focal point F of axle central ray of optical mirror slip 210
cThe position receives the light of optical mirror slip 210 refractions to produce first image (step S320).Then, photo-sensitive cell 230 moves to pairing second focal point F of axle marginal ray of optical mirror slip 210 projections
bThe position receives optical mirror slip 210 refracted rays to produce second image (step S330), as previously mentioned, can for example whether will trigger CD-ROM drive motor 226 (for example ultrasonic motor) for the triggering inductor 228 of piezoelectric inductor detects with one in system, CD-ROM drive motor 226 is driven back drive photo-sensitive cell 230 and moves to second focal point F
bThe position.Subsidiary one carries, and is the light that penetrates optical mirror slip 210 central shafts at the axle central ray of this indication, with respect to axle center light bobbin marginal ray then for penetrating the light around the optical mirror slip 210.Because the surface of optical mirror slip 210 has certain radian and optical mirror slip 210 center thicknesses with thickness is different on every side, therefore, an axle central ray and a spool marginal ray can be refracted to different focal positions, and usability optical element 230 is in these different focal position gained imagings also difference to some extent.Afterwards, elementary area 240 is according to first focal point F

Light penetration optical mirror slip 210 can be refracted to different focal positions, and causes the central area of the image that photo-sensitive cell 230 produces and the sharpness difference that there is certain degree the peripheral region.To explain in first image near the central area and the regional image difference that keeps to the side with Fig. 4 A and Fig. 4 B at this paragraph.Fig. 4 A is the synoptic diagram that photo-sensitive cell 230 of the present invention produces first image, and Fig. 4 B is the synoptic diagram of first image, please also refer to Fig. 4 A and Fig. 4 B.The axle central ray focuses on first focal point F
cThe position and the axle marginal ray focus on second focal point F
b, photo-sensitive cell 230 is in first focal point F
cThe position receives the light of refraction to produce first image 412.Because the closer to the axle central ray then more near first focal point F
cTherefore the position can produce than distinct image, and opposite correspondence then can depart from first focal point F because of the focus of correspondence near the imaging of axle marginal ray
cAnd produce than fuzzy image.In Fig. 4 B, the clear area in the first Image Acquisition district 414 expression, first image 412, this clear area with choose scope, aberration that can produce because of optical mirror slip 210 surperficial angles and human eye adjust the factors such as tolerance of the sharpness of image.Relevant adjustment mode will be sketched at a paragraph of back, not choose mode yet the present invention does not limit it.
The preceding paragraph that continues falls, and photo-sensitive cell 230 is positioned at first focal point F
cThe position produces first image 412, by optical mirror slip 210 the axle central ray behind superrefraction, drop on first focal point F
cTherefore the position has imaging more clearly near the central area.Otherwise, be refracted to second focal point F by the axle marginal ray of optical mirror slip 210
bThe position, and make the imaging of peripheral region comparatively fuzzy.The image that general digital camera is taken all has the difference of above-mentioned imaging, and the present invention moves to second focal point F with photo-sensitive cell 230 for solving the imaging difference problem after producing first image 412
bThe position produces second image.Because the imaging of the second image peripheral region is clear, so merge first and second image to produce distinct image, to solve the problem of imaging difference.In follow-up paragraph, the producing method of second image will be described with Fig. 5 A and Fig. 5 B.
Fig. 5 A is the synoptic diagram that photo-sensitive cell 230 of the present invention produces second image 512, and Fig. 5 B is the synoptic diagram of second image 512.Please also refer to Fig. 5 A and Fig. 5 B, photo-sensitive cell 230 moves to second focal point F
bPosition and produce second image 512.Also there is the imaging difference of first image 412 described in the similar previous paragraphs in second image 512 near the central area and the zone that keeps to the side.By Fig. 5 A as can be known, focus on second focal point F near the axle marginal ray
bOn, therefore work as photo-sensitive cell and in Fig. 5 B, be moved to second focal point F
bWhen the position produced second image, the zone corresponding to the axle marginal ray in second image had more clearly imaging, as the second Image Acquisition district 514 that calculates among Fig. 5 B, the i.e. clear area of second image 512.
Each step of obtaining and synthesizing of picture rich in detail in the first above-mentioned image and second image then is described, Fig. 6 is the step S340 of Fig. 3 and the detailed step process flow diagram of step S350.As shown in Figure 6, first of the calculating optical eyeglass 210 clear curve (step S610) at first.Then, try to achieve the clear area (step S620) of first image according to the optimum field rate of the first clear curve.Afterwards, the second clear curve (step S630) of calculating optical eyeglass, the first above-mentioned clear curve and the second clear curve for example are modulation transfer function (Modulation Transfer Function, MTF) curve.Optical mirror slip calculates corresponding clear curve according to the visual field rate chosen, and so-called visual field rate is the photographic images size and the ratio of the actual size of finding a view, and the big more expression photographic images of visual field rate size levels off to the actual size of finding a view more.For example in the present embodiment, the curve that the first clear curve promptly calculates with optimum field rate 0.8, the second clear curve then are the curves that calculates with optimum field rate 0.7.Then, photo-sensitive cell 230 moves one section aberration distance to second focal position by first focal position to the optical mirror slip center, and produces one second image (step S640).The aberration of step S640 indication distance is the distance between the pairing focal position of intersection point of the pairing focal position of optimum field rate of the first clear curve and the first clear curve and the second clear curve.And then, try to achieve the clear area (step S650) of second image according to the optimum field rate of the second clear curve.At last, the 3rd image (step S660) is merged in the clear area of first image 412 that obtains and the clear area of second image 512.
Explain the relation of calculating aberration distance and first, second clear picture zone with an embodiment again, Fig. 7 is the synoptic diagram of the clear curve of optical mirror slip of the present invention.As Fig. 5 A and shown in Figure 7, the optimum field rate of the first clear curve be 0.8 and in the corresponding diagram 7 position that defocuses of X-axis be made as initial point 0mm, the optimum field rate of the second clear curve is 0.7, and the position that defocuses of X-axis is-0.01mm in the corresponding diagram 7, and both spacings are aberration distance 710.Photo-sensitive cell 230 is at the first focal position F
cAfter producing first image, move one section aberration distance 710 to second focal point F to optical mirror slip 210
bThe position produces second image.First image is the clear area for the fuzzy region center on every side, and the clear area of second image sampling can remedy fuzzy part around first image just, and it is regional and obtain a universe the 3rd image clearly with second clear picture therefore to merge first image.
In some cases, for example take the thing to be taken the photograph that is moving, this thing to be taken the photograph may leave the visual range of camera lens after photographing first image 412, and can not find this thing to be taken the photograph in second image of make taking 512, or another zone that moves to visual range because of thing to be taken the photograph makes the 3rd image generation after the merging for example repeat to wait to take the photograph abnormal images such as thing.Therefore, before carrying out first image 412 and second image 512 synthetic, need carry out image rectification to first image 412 and second image 512, to avoid waiting to take the photograph thing because of the mobile incorrect phenomenon of the 3rd image of synthesizing that causes.To propose relevant method for correcting image at this problem in next paragraph first image 412 and second image 512 are carried out image rectification: at first, elementary area 240 takes out at least one first feature in first image 412.Afterwards, take out at least one second feature in second image 512.Contrast the coordinate of these first features and second feature at last,, then proofread and correct the coordinate of second feature of second image 512, make these coordinates identical with the coordinate of first feature if when existing the coordinate of at least one feature different.Illustrate above-mentioned steps, for example take a pedestrian in advancing, at first photo-sensitive cell 230 produces one first image 412, and mobile afterwards photo-sensitive cell 230 is taken one second image 512.These two images are merged into one the 3rd image.Before merging, elementary area 240 can be found out the characteristic of first image 412 earlier, for example its left foot of pedestrian in first image 412 preceding and right crus of diaphragm after.And then, elementary area 240 can be found out at least one second feature in second image 512, for example its left foot of pedestrian in second image 512 the back right crus of diaphragm preceding.Contrast first feature and second feature afterwards one by one.The feature that be very easy to find pedestrian's the left and right sides pin this moment is different, and the pedestrian who is very easy to find shooting in view of the above walks.This moment, elementary area 240 just can further carry out the image rectification step, after making first image 412 and the coordinate position of corresponding feature in second image 512 conforming to, just proceeded to merge the step of the 3rd image.In addition,, then keep (or deletion) this feature if in second image 512, have unexistent feature in first image 412, make the 3rd image after the merging more become true.The technological means that relevant characteristics of image obtains is not confined to mode of the present invention, and those of ordinary skill in the art can partly carry out suitable change according to its understanding to this.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and modification according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
