All clear for the striped and the image that guarantee many groups nicking picture that this device is captured, this device has been installed compressing tablet as shown in Figure 3 and has been lifted chip architecture on camera bonnet (61), has installed on grating seat (56) as Fig. 7 to topsheet structures shown in Figure 10.Compressing tablet is lifted sheet screw rod (62) and is connected with the former film pressure plate of camera, and the energy of rotation that the compressing tablet of lifting sheet screw rod (62) threads engaged with compressing tablet is lifted the different directions of sheet knob (63) drives compressing tablet and lifts sheet screw rod (62) and make film pressure plate push down film (64) or make film pressure plate leave film (64) certain distance.Film pressure plate is pushed down film (64) in this device shooting process, makes the medicine face of film (64) be close to original screen panel (58), makes captured nicking picture clear; Film pressure plate leaves film (64) in the roll film of this device and reviewing process, and film (64) and original screen panel (58) all are not scratched; For guarantee film pressure plate push down film (64) back original screen panel (58) when mobile film (64) do not move, film top nail (65) and top nail set screw (66) thereof have been installed in grating seat (56), sheet muscle face (67) on the grating seat (56) flushes with original screen panel (58) plane, high muscle face (68) on the grating seat (56) is to the thickness of the distance between the sheet muscle face (67) less than film (64), (as being the thickness that 120 films also should comprise lining paper), after film pressure plate is pushed down film (64), theoretical gap between film (64) medicine face and the original screen panel (58) is zero, and film top nail (65) heads into the degree of depth of film (64) and is advisable with 1/3rd of film (64) thickness.
As Fig. 1 to Fig. 4, Figure 10 and shown in Figure 12, this device slit scan mechanism is by object lens (28), objective holder (29), preset aperture ring (30), sector gear regulating ring (34) or oblique covering of the fan plate regulating ring (45), be fixed on the slit plate slide (32) on the camera body (55), being positioned at slit plate slide (32) by screw (31) goes up and limits its object lens that can only do to move horizontally and move horizontally plate (33), slide bar left supported plate (7), one end is positioned at slide bar left supported plate (7) slit plate last and that slit plate slide (32) is slided thereon and decides plate (69), revolving nail (70) places slit plate to decide plate (69) and can regulate the slit plate of slit gap width and move plate (71) by revolving nail (70), the macroshot camera lens (72) and the original screen panel (58) that are installed on the slit plate slide (32) are formed.When objective focal length is longer, macroshot camera lens (72) can be removed by this mechanism, in the case, slit plate is decided slit jaw that the moving plate (71) of plate (69) and slit plate pastes mutually and the distance between original screen panel (58) the grating face less than 1/10th of object lens (28) focal length, and original screen panel (58) with respect to grating seat (56) move horizontally direction and object lens (28) with respect to slit plate slide (32) to move horizontally direction opposite.
The instantaneous compound stereoscopic camera of single object lens three slit scans embodiment.
The transmission case travel mechanism of present embodiment, focusing (range finding) assemble synchronizing linkage and grating travel mechanism all as previously described, below an emphasis three slit scans of present embodiment and the formation principle and the forming process of three groups of nicking pictures are described.
Extremely shown in Figure 11 as Fig. 1, if shot subject A is L apart from the distance of object lens (28), sector gear regulating ring (34) or tiltedly covering of the fan plate regulating ring (45) according to this apart from focusing (range finding), bearing pin axis deviation rotating disk (40) rotation center of nut bearing pin (37) or shift fork slide block bearing pin (47) (nut bearing pin (37) or shift fork slide block bearing pin (47) bearing pin axle center overlapped with rotating disk (40) center when focussing distance was the infinite distance), at this moment object lens (28) the photocentre distance of deciding the moving contacted plane of plate (71) of plate (69) and slit plate from slit plate is f+ △ f, the picture that A is ordered is imaged on this imaginary plane, macroshot camera lens (72) is to the picture on this imaginary plane focus (promptly focusing to slit), picture on slit and this imaginary plane all is imaged on original screen panel (58) and the contacted plane of film (64) clearly, then the fixing installation site of macroshot camera lens (72) on slit plate slide (32).
The synthetic nicking picture of three slit scans is to realize like this.
Extremely shown in Figure 11 as Fig. 1, the subject that is in plane, A point place becomes inverted image by object lens (28) at the slit imaginary plane, this picture is imaged on once more by macroshot camera lens (72) to be become upright picture on original screen panel (58) and the side plane that film (64) pastes mutually (this looks like to be stopped by the slit plate lightproof part before not by slit scan, be imaginary picture, film (64) medicine face is close on original screen panel (58) plane.
As shown in figure 11, supposing is not having slit plate to decide plate (69), slit plate moves under the situation of plate (71) and original screen panel (58), being installed in macroshot camera lens (72) in the camera body (55) and film (64), to make its distance with transmission case (1) be 1 dextrosinistral moving horizontally, and object lens (28) are assembled in object lens parallel-moving type focusing (range finding) under the effect of synchronizing linkage and to be moved horizontally the moving plate (33) of plate with object lens and do apart from the moving horizontally from left to right (△ l=L(f+ △ f)/L) that is △ l with respect to distance element phtographic lens (72) and film (64) 1 positions.L in this sequence photography process of object lens (28) and distance element phtographic lens (72) and △ L are decomposed into eight sections to be analyzed for nine times, its situation is as follows: when object lens (28) and distance element phtographic lens (72) when all being in initial point position, A point, object lens (28) photocentre and macroshot camera lens (72) photocentre are on the same straight line, the A point is imaged on the imaginary plane A0 point by object lens (28), and the A0 point is imaged on by macroshot camera lens (72) on center A0 ' of film (64); When macroshot camera lens (72) be moved horizontally to left l1 apart from the time, object lens (28) then are moved horizontally to △ l1 distance to the right with respect to the l1 distance, the A point is imaged on the A1 point by object lens (28), the A1 point also is imaged on by macroshot camera lens (72) on center A1 ' of film (64), overlap with A0 ', when macroshot camera lens (72) be moved horizontally to left l2 apart from the time, object lens (28) then are moved horizontally to △ l2 distance to the right with respect to the l2 distance, the A point is imaged on the A2 point by object lens (28), the A2 point is on A2 ' by the center that distance element phtographic lens (72) also is imaged on film (64), overlaps with A0 ' and A1 '; The rest may be inferred, until be moved horizontally to left when distance element phtographic lens (72) 18 apart from the time, object lens (28) then are moved horizontally to △ l8 distance to the right with respect to the l8 distance, the A point is imaged on the A8 point by object lens (28), the A8 point is on A8 ' by the center that macroshot camera lens (72) is imaged on film (64), all overlaps with A0 ' point, A1 ' point, A2 ' point, A3 ' point, A4 ' point, A5 ' point, A6 ' and A7 '; If this moment, subject was to be in A point position and to be parallel to distance element phtographic lens (72) moving direction and the picture on a width of cloth plane on film (64) plane, so film (64) go up just can form this width of cloth picture clearly as, the A point at picture center also can be in the center of film (64); If this moment, subject was real three-dimensional scenery, be in shot subject A point so and be parallel to macroshot camera lens (72) moving direction and the scenery on film (64) plane will film (64) go up to form clearly as, and for A point and object lens (28), leave the A point and away from the scenery of object lens (28) with leave A point and then be overlapping with ambiguous near the picture that the scenery of object lens (28) is gone up formation at film (64).
According to above-mentioned principle, decide plate (69) and the moving plate (71) of slit plate if between object lens (28) and macroshot camera lens (72), add slit plate, add original screen panel (58) in film (64) front, macroshot camera lens (72) is scanned the picture that object lens (28) form on slit when moving horizontally, and making original screen panel (58) carry out fine motion, this fine motion is that the grating travel mechanism by foregoing device realizes; Install the fine motion of peculiar rule by original screen panel (58) by this, the scanning of in the single pass process several slits being carried out overall process just can be gone up at film (64) and be formed several groups and arrange in order staggered alternate nicking pictures.
Below three slit scans and nicking picture forming process are described.Among Figure 11 macroshot camera lens (72) from right to left move horizontally and object lens (28) moving horizontally from left to right all is continuous in instantaneous, we are divided into 9 kinds of states of 8 equal portions with this process and analyze.When object lens (28) and macroshot camera lens (72) when all being in initial point position, scenery is imaged on slit plate by object lens (28) and decides the moving plate of plate (hereinafter to be referred as slit plate (69,71)) on the plane of pasting mutually, from slit plate (69,71) on right-to-left number (down with) article one slit similarly be scenery the right partly, this picture is imaged on the right of original screen panel (58) by macroshot camera lens (72), through the shading of original screen panel (58), go up the latent image that forms first group of nicking picture right-hand component at film (64); When macroshot camera lens (72) be moved horizontally to left l1 apart from the time, object lens (28) then are moved horizontally to △ l1 distance to the right with respect to the l1 distance, at this moment on article one slit similarly be scenery in the middle of partly, this picture is gone up the middle latent shape partly of first group of nicking picture of formation by the shading of original screen panel (58) at film (64); When macroshot camera lens (72) be moved horizontally to left l2 apart from the time, object lens (28) then are moved horizontally to △ l2 distance to the right with respect to the l2 distance, at this moment similarly be the left portion of scenery on article one slit, this picture is imaged on the left side of original screen panel (58) by macroshot camera lens (72), through the shading of original screen panel (50), go up the latent image that forms first group of nicking picture left portion at film (64); When macroshot camera lens (72) be moved horizontally to left l3 apart from the time, object lens (28) then are moved horizontally to △ l3 distance to the right for the l3 distance, they begin corresponding second slit, at this moment on the second slit similarly be scenery the right partly, this goes up the latent image that forms second group of nicking picture the right part as the right that is imaged on original screen panel (58) by macroshot camera lens (72) through the shading of original screen panel (58) at film (64); When macroshot camera lens (72) be moved horizontally to left l4 apart from the time, object lens (28) then move right to △ l4 distance with respect to the l4 distance, at this moment on the second slit similarly be scenery in the middle of partly, this picture is imaged on the middle part of original screen panel by macroshot camera lens (72), through the shading of original screen panel (58), on film, form the middle latent image partly of second group of nicking picture; When macroshot camera lens (72) be moved horizontally to left l5 apart from the time, object lens (28) then are moved horizontally to △ l5 distance to the right with respect to the l5 distance, at this moment similarly be the left portion of scenery on the second slit, this picture is imaged on the left side of original screen panel (58) by macroshot camera lens (72), through the shading of original screen panel (58), go up the latent image of second group of nicking picture of shape layer left portion at film (64); When macroshot camera lens (72) be moved horizontally to left l6 apart from the time, object lens (28) then are moved horizontally to △ l6 distance to the right with respect to the l6 distance, they begin corresponding the 3rd slit, at this moment on the 3rd slit similarly be scenery the right partly, this picture is imaged on the right of original screen panel (58) by macroshot camera lens (72), through the shading of original screen panel (58), go up the latent image that forms the 3rd group of nicking picture the right part at film (64); When macroshot camera lens (72) be moved horizontally to left l7 apart from the time, object lens (28) then are moved horizontally to △ l7 distance to the right with respect to the l7 distance, at this moment on the 3rd slit similarly be scenery in the middle of partly, this picture is imaged on the middle part of original screen panel (58) by macroshot camera lens (72), through the shading of original screen panel (58), go up the latent image that forms the middle part of the 3rd group of nicking picture at film (64); When macroshot camera lens (72) be moved horizontally to left l8 apart from the time, object lens (28) then are moved horizontally to △ l8 distance to the right with respect to the l8 distance, at this moment similarly be the left-hand component of scenery on the 3rd slit, this picture is imaged on the left side of original screen panel (58) by macroshot camera lens (72), through the shading of original screen panel (58), go up the latent image that forms the 3rd group of nicking picture left portion at film (64); So far, the instantaneous compound stereoscopic imaging program of single object lens three slit scans is finished, and has formed three groups of staggered alternate nicking pictures on film (64).
Its width of grating fringe of being illustrated on slit of being illustrated on the slit plate on Figure 11 (69,71) and the film (64) all is through having exaggerated; The slit of this device is actually several very thin seams of equidistant arrangement, and subject process object lens (28) imaging thereon also are very thin nicking pictures.A nicking cross section of being illustrated on Figure 11 film (64), in fact go up formed one group of nicking picture at film (64) in one section continuous sweep process having represented macroshot camera lens (72) that slit is carried out in this device, the width of this group nicking picture accounts for 1/3rd of film (64) whole image width in Figure 11.Slit is carried out in the process of continuous sweep at macroshot camera lens (72), the picture of slit is gone up continuous sweep at original screen panel (58), original screen panel (58) then installs the fine motion that distinctive rule is carried out horizontal direction by this, for each the bar grating light transmission strip on the original screen panel (58), the inswept thereon time of transmissive slit on the slit plate (69,71) is less than the time of the light tight part shading thereon on the slit plate (69,71) far away; If the printing opacity grating fringe width on the original screen panel (58) meets the specific requirement of this device, macroshot camera lens (72) article one slit is swept go over will scan the second slit time after, on film (64), will form one group of complete nicking picture; The width that the width of this each striped of group nicking picture equals the last printing opacity striped of original screen panel (58) adds the fine motion amount of the moment original screen panel (58) of inswept this striped of slit, should be 1/3rd of the last every pair of grating fringe of original screen panel (58) (printing opacity partly adds light tight part) width for three these width of slit scan device; After first group of nicking picture forms, macroshot camera lens (72) will scan the second slit, scan the vertical bar picture line of going up formation at film (64) in the back and answer the vertical bar of adjacent first group of nicking picture to draw line; The realization of this rule by two screws (59) adjustment of regulating this device grating travel mechanism and fixedly the angle of inclination of take-up housing (60) on grating slide plate (57) finish; After finishing, second group of nicking picture, finish the 3rd group of nicking picture again to the 3rd slit scan; Synthetic so the analogizing of many group nicking pictures.According to column mirror grating stereo photo principle, observe upright column mirror grating stereo photo simultaneously with eyes, left eye is observed should to be that to draw line be left picture for the vertical bar on the right of being covered of post mirror striped, right eye is observed should be the vertical bar on the left side that covered of post mirror striped to draw line be right picture, eyes are observed then simultaneously can produce stereoscopic sensation in brain.It similarly is upright picture that film shown in Figure 11 (64) is gone up formed, thus object lens (28) on the right the time formed every the nicking of article one slit scan of correspondence all should be arranged in the left side of every pairing unit of post mirror; Object lens (28) formed every nicking of the second slit scan of correspondence when the centre all should be arranged in the centre of every pairing unit of post mirror; The 3rd formed every the nicking of slit scan of correspondence all should be arranged in the right of every pairing unit of post mirror during object lens (28) on the left side.
Be to be divided into 8 sections and to simplify the analyses that the back is done 9 times above to the scanning of the instantaneous compound stereoscopic camera of single object lens three slit scans and nicking picture are synthetic.This device in the actual photographed process section and time be continuous with countless; In theory, the slit number the more and the printing opacity striped on the original screen panel (58) the more thinner, it is many more then to go up the nicking group of picture number that forms at film (64), the pixel on the film (64) is just many more, picture is also just fine and smooth more.This device is to adjust exposure by the width of regulating moving plate (71) control of slit plate slit, and the adjusting of slit width plays a part the general camera film speed and regulates.This device transmission case (1) right-to-left and motion process from left to right all are working routines, need install distinctive rule by this when taking operates, must rotate compressing tablet during shooting and lift sheet knob (63) and make film pressure plate push down film (64), also must rotate compressing tablet when roll film and reviewing and lift sheet knob (63) and make film pressure plate leave film (64) one segment distances; Focusing (range finding) must accurately influence image quality and stereoeffect otherwise will make the shot subject that should assemble in the picture produce dislocation; The base of this device must with the supporting use of photographic tripod.
Under the prerequisite that guarantees the clear-cut texture degree, this device preferably is embodied as four slits in force or more than four slits, just goes up at film (64) and form nicking picture more than four groups or four groups, can increase the image information amount like this, enlarge picture and see angle, improve picture element and stereoscopic sensation.Because this device increases a group number need of nicking picture and increases slit bar number, and install the fine motion amount that distinctive rule is adjusted original screen panel (58) by this, under the situation that film (64) photographic layer granularity and clear-cut texture degree allow even be embodied as that the nicking picture all is not difficult more than 10 groups or 10 groups.
According to this apparatus features, adopt the common standard object lens to mix short focal length macroshot camera lens and can be embodied as the small-sized base that adopts 135 films and be embodied as the medium-sized base that adopts 120 films; Adopt long-focal length lens to mix the macroshot camera lens and can be embodied as the large-scale base that adopts the page or leaf sheet; Can also be embodied as the such pattern of removing the macroshot camera lens of Figure 12 when adopting long-focal length lens, because object lens (28) focal length is long, slit plate (69,71) as then very little near original screen panel (58) as far as possible in the scattering that film (64) upward produces, can not bring very big influence to image quality, device A point shown in Figure 12 is formed by object lens (28) similarly to be through the shading direct imaging forms three groups of nicking pictures behind the slit and through original screen panel (58) on film (64) medicine face, only needs to carry out moving of original screen panel (58) by column mirror grating stereo photo nicking arrangement regulation and gets final product.
Be embodied as point-and-shoot if adopt short-focus objective to mix ultrashort focal length macroshot camera lens, only need range finding and assemble synchronously, do not focus; Install the motion of each parts enough freely at this, sweep velocity is enough fast, this device volume is dwindled as far as possible and integrated, adopts under the situation of two-handed hand-held and may be embodied as the instantaneous compound stereoscopic camera of the many slit scans of hand-held list object lens.To make stereocamera enter average family like that, satisfy the growing material and cultural life needs of people, bring huge economic benefit and social benefit.
