The application is dividing an application of following patented claim: application number: 99107652.4, and the applying date: 1999.1.27, denomination of invention: photograph printing device, electronic image input device, negative scanner, defect identification method, program recorded medium and image repair method
Technical field
The present invention relates to: 1) photograph printing device, for example be located on picture processing device or the photo printing machine, by the negative film of record original image or liquid crystal display cells, the PLZT photohead that drives by the picture signal of corresponding original image, DMD information such as (digital micromirror devices) preserve body with rayed on photosensitive material, thereby above-mentioned original image is printed on the photosensitive material; 2) on above-mentioned photograph printing device, equip the electronic image input device that CCD imaging apparatuss such as (charge-coupled image sensors) constitutes; 3) be used for negative scanner digital printing system for example, discern above-mentioned original image by the flash ranging light (scanning) that the egative film via the record original image is obtained; 4) be identified in the defect identification method of the existence of the defective on the above-mentioned egative film; 5) recording medium of recording defect recognizer; 6) reparation is by the image repair method in the image deflects zone of photometry acquisition.
Background technology
Up to the present, for example the negative film of record original image is configured in the photosensitive material front and utilizes the above-mentioned negative film of process that rayed is had various schemes at the photograph printing device that original image is printed on the photosensitive material.
Most of light source that uses Halogen lamp LED as the irradiation photosensitive material in these photograph printing devices.And insert in the light paths by red, green correspondence, blue or green three kinds of cut-off filter of all kinds, that have different mutually dichroisms, so that the light of Halogen lamp LED is adjusted to the light that is fit to printing.
Yet in using the photograph printing device of Halogen lamp LED, there is following defective as light source:
1), and for example must adopt cooling fan etc. to force cooling body because Halogen lamp LED sends the unwanted heat of many printings.Under the situation of configuration cooling fan,, and make printing effect bad because of the dust around inciting somebody to action blows into optical system.
2) owing to also need to make the dichroism of Halogen lamp LED stable DC stable power supply, light modulation light filter and the cut-off filter that is used to remove infrared light or ultraviolet light, institute so that device occur maximizing.
Therefore 3) if Halogen lamp LED is lighted the back without certain hour, then can not obtain to print desirable light quantity,, also must often light Halogen lamp LED even when not printing.Thereby the electric power that Halogen lamp LED is consumed increases.In addition, for the illumination that prevents Halogen lamp LED when not printing is mapped to as on the sensitized paper of photosensitive material and must dispose tripper between sensitized paper and Halogen lamp LED, this has increased component parts again.
4) because the light quantity difference around optical axis and the optical axis is bigger, so thereby when formation made light diffusion from Halogen lamp LED form the diffusing device of the necessary area source of printing, light loss was big.
5) if often light Halogen lamp LED, under the many situations of printing photographic piece number, the heat of Halogen lamp LED can produce harmful effect to negative film.
The negative film of record original image is being configured in the front of light-measuring mechanism, by by light-measuring mechanism to be radiated at light on the negative film measure on the negative scanner of discerning above-mentioned original image also can produce above-mentioned 1)-5) and defective.Above-mentioned negative scanner links to each other with digital printer by computing machines such as for example personal computers, and the image of the above-mentioned negative scanner of input is exported from digital printer.
Relative therewith, for example open in the flat 8-22081 communique in the disclosed photo printing machine and negative scanner the spy, use dichroism mutually different a plurality of light emitting diodes (the following LED that simply is designated as) as light source, prevent the defective that causes because of Halogen lamp LED whereby.Below the structure of the exposure projections mechanism of disclosed photograph printing device in the above-mentioned communique is carried out brief description.
As shown in figure 33, above-mentioned photograph printing device is equipped with led light source 101, diffusing panel 102 and lens 103.
Led light source 101 is that a plurality of LED 101a of the light of, cyan red, green with launching respectively are configured to rectangular.At this moment each LED 101a is as shown in the drawing, and its sensing is arranged to parallel with optical axis L.Respectively each LED 101a is carried out the control of ON/OFF by not shown light source driving mechanism in addition, each LED 101a is carried out one by one the control of fluorescent lifetime and/or glorious degrees.
Diffusing panel 102 is configured in the light emitting side of led light source 101, is used to make the ejaculation light diffusion of led light source 101.Lens 103 look like incident light to be imaged on the color sensitive paper 105 as photosensitive material.
In such structure, when each the LED 101a that makes led light source 101 lighted, the light that penetrates from each LED 101a saw through successively to be configured in and prints locational negative film 104 after diffusing panel 102 diffusion, and lens 103 arrive on the color sensitive paper 105.Make the original image imaging that is recorded on the negative film 104 whereby and be printed on the color sensitive paper 105.
Disclosed negative scanner is to change above-mentioned color sensitive paper 105 into image plane sensor 106 and the device of formation in above-mentioned communique.Therefore, in above-mentioned negative scanner, when each LED 101a of led light source 101 was lighted, the light that penetrates from each LED 101a saw through negative film 104 successively after diffusing panel 102 diffusions, and lens 103 arrive image plane sensor 106.The original image that is recorded on the negative film 104 is imaged on the sensitive surface of above-mentioned image plane sensor 106.Then, for example above-mentioned negative scanner is linked to each other with digital printer, then can from above-mentioned digital printer, discharge the photo of the above-mentioned original image of record by computing machines such as personal computers.
On the other hand, because sensing and the optical axis of each the LED 101a in the disclosed photograph printing device be arranged in parallel in above-mentioned communique, so influences such as aberration that the reason design of Optical System causes, the light quantity that is radiated at the light on color sensitive paper 105 edge parts is reduced, the phenomenon that central part and circumference density unevenness are even, irregular colour is even occurs.
Once considered to adopt for example following method to prevent to produce these defectives.One of method be make diffusing panel 102 with central authorities thick and to circumference gradually the mode of attenuation form, light is dispersed more, thereby is reduced light quantity at color sensitive paper 105 central parts, the light quantity of the circumference of color sensitive paper 105 is increased.And another kind of method is that diffusing panel 102 is made of the frosted glass with the roughness that with the naked eye almost can not have an X-rayed, equally with said method makes light diffusion.
, because light loss is increased, so must make the time shutter of each LED 101a elongated or the glorious degrees of each LED 101a is increased above-mentioned making.The result causes the problem that need take a long time when adjusting density unevenness spares.
Figure 34 shows each the LED light intensity that is radiated on the color sensitive paper 105 and distributes, and demonstrates near the intensity height in center of hot spot, and the outside intensity in the center of leaving reduces gradually.
Because in above-mentioned communique in the disclosed photograph printing device, the sensing of each LED 101a be arranged in parallel with optical axis, thus as shown in the drawing, on color sensitive paper 105, the configuration of corresponding each the LED 101a of the hot spot of each LED 101a is scattered, and irregular colour is even clearly.Promptly this irregular colour is even by being radiated at hot spot on the color sensitive paper 105 by causing mutually with each LED 101a corresponding one by one showing.
Therefore, consider to be used as reducing the even method of this irregular colour as the method that LED 101a is radiated on the negative film 104 diffused light with the wide LED of directive property.Even in this way, do not make light diffusing principle owing to not change, so still have to prolong the time shutter of each LED101a in order to reduce light loss or increase the glorious degrees of each LED 101a.Its result still can cause and carries out the even problem that needs spended time when whole of irregular colour.
People also consider to utilize the narrow LED of directive property to increase by the number that makes LED101a as much as possible as LED 101a, make hot spot intensive and eliminate the even method of irregular colour.It is even good more to reduce irregular colour, and the LED 101a of configuration is many more, and this is difficulty very, in addition, controls a plurality of LED 101a thick and fast in fact also near impossible even disposed.
In addition, in the structure of above-mentioned negative scanner, exist upsetting on the negative film 104 from led light source 101 to image plane sensor under the situation of 106 this defective of light path, can the defect image (for example blank) corresponding to above-mentioned defect part directly be apparent on the scan image.This is caused by following reason: the light that is incident on the above-mentioned defective reflects the light path of leaving arrival image plane sensor 106 on this defect part, makes above-mentioned defect image form deficiency in light quantity.And, even the phenomenon of the deficiency in light quantity that causes because of abnormal refraction etc. like this can take place when adhering to dust or foreign matter on negative film 104 surfaces too.
But the above-mentioned existing negative scanner of use led light source 101 can not be discerned the defective on the negative film 104.When promptly on negative film 104, having defective, the blank as described above though on the scan image that obtains by image plane sensor 106, develop, even but people's naked eyes can to discern this blank be image deflects, it is defect image that computing machine can not clearly be told this blank, or is exactly the formal image of the original image of corresponding record on negative film 104 at all.
Consequently, above-mentioned negative scanner exists on the negative film 104 under the situation of above-mentioned defect part, can occur only repairing corresponding above-mentioned rejected region defect image, can not obtain not existing defect image to carry out the problem that high-quality is printed.

That is, penetrated from its head by the major part of the ejaculation light of LED group 11, simultaneously, it is almost all to the direction ejaculation of sensitized paper 8.But the light that the head from LED11R, 11G, 11B that also has trace penetrates to LED substrate 12a side.Therefore,, make of the direction reflection of the light of directive LED substrate 12a side, thereby make light quantity increase to the direction of sensitized paper 8 to sensitized paper 8 by on LED substrate 12a surface, reflectance coating being set.Thereby can effectively utilize emergent light from LED group 11, the result can reduce the light loss of emergent light.
Diffusing panel 13 is the frosted glass with the roughness that almost can with the naked eye have an X-rayed, and is configured near each head of LED group 11, and its periphery is fixed on the wall 12b.In the present embodiment, the employing angle of visibility is LED11R, 11G, the 11B below 45 °.Make from the suitable diffusion of the light of LED11R, 11G, 11B by diffusing panel 13.In addition, if, then there is no need to be provided with diffusing panel 13 with LED11R, 11G, 11B with suitable angle of visibility (for example about 18 °).
As shown in Figure 9, diaphragm 14 has the peristome 14a corresponding to each LED11R, 11G, 11B, and the internal diameter of peristome 14a is mutually different to each diaphragm 14.Therefore, by the diaphragm 14 with peristome 14a of regulation internal diameter optionally being configured in the above-mentioned light path between LED11R, 11G, 11B and the diffusing panel 13, can suitably adjust the angle of visibility of each LED11R, 11G, 11B.
Also can be arranged on each LED11R, 11G, the 11B by the diaphragm that the internal diameter of peristome is variable, adjust the angle of visibility of each LED11R, 11G, 11B, optionally be inserted in the above-mentioned light path to replace a diaphragm 14 of regulation by adjusting above-mentioned peristome.
Like this, in the present embodiment, utilize LED11R, 11G, 11B can produce following effect and effect as light-emitting component.
1) no longer need absorb the hot line light filter, light modulation light filter, cut-off filter etc. once being necessary cooling fan under as the situation of light-emitting component with Halogen lamp LED.Thereby can simplify the structure of light source portion 5.In addition, because there is not cooling fan, thus dust on every side can be blown into optical system, thus can carry out high-quality printing.
2) because dichroism is stable, so direct supply can be with the simple power supply that voltage is added on IC (integrated circuit) control circuit board.Therefore direct supply that can be special, thus can prevent that locking apparatus maximizes.In addition, because dichroism is stable, so can carry out the light modulation management easily by the ON/OFF of control LED11R, 11G, 11B.
3) owing to LED11R, 11G, 11B being carried out ON/OFF control, so can not light LED11R, 11G, 11B unless necessary.Therefore compare with the situation of utilizing Halogen lamp LED and can reduce power consumption significantly.In addition, because under situation about not printing, cut off LED11R, 11G, 11B, so there is no need between sensitized paper 8 and LED11R, 11G, 11B, tripper to be set.The result can make component count reduce, photo printing machine 1 simple in structure.
4) the optical axis light quantity difference peripheral with it does not have Halogen lamp LED so big.Therefore can be than the light loss during as light source reduces with Halogen lamp LED.
5) owing to LED11R, 11G, 11B being carried out ON/OFF control, so LED11R, 11G, 11B are lighted continuously.Even therefore under the more situation of the photo piece number of printing, also can prevent owing to LED11R, 11G, 11B generate heat to the damage of negative film.
Describe LED group 11 below in detail.
In Fig. 7, when LED substrate 12a was divided into four quadrants of the first~the four-quadrant, establishing the LED that belongs to first quartile was LED11R 1, 11G 1, 11B 1, the LED that belongs to second quadrant is LED11R 2, 11G 2, 11B 2, the LED that belongs to third quadrant is LED11R 3, 11G 3, 11B 3, belonging to four-quadrant LED is LED11R 4, 11G 4, 11B 4
As shown in Figure 7, near the central portion of LED group 11, amount to 12 LED of intensive configuration with the number distribution by every kind of color.Specifically, make four LED11R that constitute LED group 11 1-R 4Near the center of LED substrate 12a with interconnected state configuration, with LED11R 1-R 4Under the state that connects, four LED11G 1-G 4Point symmetry configuration (in other words, the optical axis L of printing lens 6 relatively is symmetrical), simultaneously, four LED11B 1-B 4The point symmetry configuration.Make LED11R whereby 1, 11G 1, 11B 1Form one group for three, remaining LED is also by one group of three corresponding composition of every kind of color.Constitute LED group 11 by amounting to four groups of LED.In addition, optical axis L is by the center of LED substrate 12a.
By like this LED11R1-R4 that glows being configured on the proximal most position of optical axis L, can effectively utilize the often ruddiness of deficiency in light quantity.
At each LED11R, 11G, among the 11B, briliancy one fluorescent lifetime is regularly set than considering the versicolor photosensitive property in the sensitized paper 8, for example is set at LED11B: LED11G: LED11R=1: 2: 5~6.By making LED11R, 11G, 11B can replenish the often the most not enough ruddiness of light quantity, handle thereby can carry out high-quality printing so that such ratio is luminous.
In addition, above-mentioned ratio also can be fluorescent lifetime one luminance ratio regularly.Therefore the number of the LED of LED group 11 should not limit in the present embodiment 12, and is just blue or green, green, red of all kinds, if take into account configuration space and make the briliancy of LED and fluorescent lifetime long-pending to satisfy above-mentioned 1: 2: 5~6 settings just passable.
In addition, each LED11R, 11G, the relative optical axis L tilt angle theta of 11B are installed, and pointed to towards optical axis L.Utilize Fig. 8 to be explained below.
Fig. 8 shows and only chooses for example four-quadrant LED11R 4, 11G 4, 11B 4Stereographic map.By as can be known with the horizontal plane X among the figure, LED 11G 4, 11B 4The relative optical axis L horizontal direction tilt angle theta of difference 1Equally, by vertical plane Y as can be known, 11G 4, 11B 4Relative optical axis L is in vertical direction tilt angle theta 2 respectively.In addition, also can make angle θ 1=angle θ 2.
In addition, though not shown, the LED11R of other first~third quadrant, 11G, 11B are also identical with above-mentioned situation.The above-mentioned angle θ of various conditions, θ such as the lens kind that consideration is used in optical system (focal length, bore etc.), picture format, printing multiple 1, θ 2In 0~30 ° scope, set.
By with LED11R, 11G, the relative optical axis L inclination of 11B predetermined angular θ configuration, just can be as shown in Figure 1, even under the situation of optical system generation aberration, also can positively make the neighboring area that shines sensitized paper 8 from the emergent light of light source portion 5.
Therefore there is no need in prior art, make from the undue diffusion of the light of LED11R, 11G, 11B.Therefore also there is no need in order to replenish the control that the light loss that produces because of diffusion of light is carried out prolonging exposure time or improved glorious degrees.
In addition, relative the optical axis L tilt angle theta disposes by making LED11R, 11G, 11B, occurs the hot spot one to one with each LED11R, 11G, 11B just can not resembling in the prior art on sensitized paper 8.The result is even because of suppressing irregular colour to a certain extent, and with above-mentioned the same, there is no need to make from the undue diffusion of the light of LED11R, 11G, 11B.Therefore, by making LED11R, 11G, the relative optical axis L inclination of 11B predetermined angular θ configuration just can adjust inhomogeneous and color inhomogeneous of concentration easily.
The inclination angle of each LED11R, 11G, 11B can for example suitably adjusted to the fixedly stage of the LED of each LED11R, 11G, 11B substrate 12a substrate during fabrication.Above-mentioned inclination angle also can be adjusted by making above-mentioned leg curvature ormal weight after being fixed on the shank of each LED11R, the 11G that for example are made of tinsel, 11B on the LED substrate 12a.
The following describes determining that by every ternary LED11R, 11G, 11B this point of rayed district on sensitized paper 8 describes.
Light source portion 5 is made of a plurality of LED11R, 11G, 11B, and is divided into the first~the four-quadrant a plurality of groups.By the above-mentioned every group rayed zone of determining sensitized paper 8.In the present embodiment, the first~the four-quadrant LED11R, 11G, 11B relative with the rayed district on the sensitized paper 8 print lens 6 in be formed centrally the position relation of symmetry.
LED11R from first quartile shown in Figure 7 1, 11G 1, 11B 1Light as shown in Figure 9, see through diaphragm 14 in turn, diffusing panel 13, negative film 7 is radiated on the area I of sensitized paper 8 after printing lens 6.In with figure, area I is towards the zone of printing lens 6 lower-lefts in sensitized paper 8.Equally, from the LED11R of second quadrant 2, 11G 2, 11B 2Rayed on the area I I of sensitized paper 8, from the LED11R of third quadrant 3, 11G 3, 11B 3Rayed on the area I II of sensitized paper 8, from four-quadrant LED11R 4, 11G 4, 11B 4Rayed on the area I V of sensitized paper 8, area I I-IV is towards printing lens 6 are rotated counterclockwise formation respectively from area I zone on sensitized paper 8.
Figure 10 a shows the LED11R that belongs to third quadrant making 3, 11G 3, 11B 3Luminous quantity bigger and test the CONCENTRATION DISTRIBUTION on sensitized paper 8 under the print situation than the luminous quantity of the LED11R that belongs to other quadrant, 11G, 11B.And Figure 10 b shows the LED11R that belongs to third quadrant making 3, 11G 3, 11B 3Angle of visibility littler and test the CONCENTRATION DISTRIBUTION on sensitized paper 8 under the print situation than the angle of visibility of the LED11R that belongs to other quadrant, 11G, 11B.Demonstrate in addition in the concentric multiple circle in these figure, high more the closer to circle central area concentration, decentering concentration far away more is low more.On sensitized paper 8,, the CONCENTRATION DISTRIBUTION of these area I~IV obtains a CONCENTRATION DISTRIBUTION by being synthesized.
Can adjust the luminous quantity of each LED according to the briliancy of LED and/or the fluorescent lifetime of LED.In addition, can adjust the luminous quantity of each LED according to the irradiation light wavelength.At this moment, use LED with a plurality of can be single luminous wavelength peaks that can be luminous (for example オ プ ト ラ Application ス company make multi-colored led, VLA101RGB), can change luminous quantity by making each peak wavelength ON/OFF respectively.Can control exposure whereby to sensitized paper 8.
That is to say, though the adjustment of the luminous quantity of each LED can be by changing the briliancy of LED, in the fluorescent lifetime of LED and the irradiates light wavelength one of at least and carry out, but under the plural situation in changing these three physical quantitys, as long as it is the suitableeest even so that the even irregular colour of density unevenness not to take place that each physical quantity is changed.
Like this, when determining rayed district on the sensitized paper 8, can carry out the adjustment that overall density is inhomogeneous, irregular colour is even of sensitized paper 8 to each area I-IV by the first~the four-quadrant LED11R, 11G, 11B.In the present embodiment promptly, only need the luminous quantity of the ternary LED by adjusting the regulation zone on the corresponding sensitized paper 8 and angle of visibility etc. just can carry out uneven adjustment effectively to sensitized paper 8 integral body.Therefore, can more easily carry out the even adjustment of the even irregular colour of density unevenness of sensitized paper 8 sense bodies.
In addition, Figure 11 a shows and diminishes at the inclination angle that makes each LED11R, 11G, 11B and test the CONCENTRATION DISTRIBUTION on the sensitized paper 8 under the print situation.And Figure 11 b shows the CONCENTRATION DISTRIBUTION on the sensitized paper 8 when the inclination angle change that makes each LED11R, 11G, 11B is tested print greatly.
In Figure 11 a, can find that the hot spot from the emergent light of each quadrant concentrates on the central authorities of sensitized paper 8, the CONCENTRATION DISTRIBUTION of central portion is roughly even.In Figure 11 b, concentrate on the place, four angles of sensitized paper 8 from the hot spot of the emergent light of each quadrant, even in this case, the CONCENTRATION DISTRIBUTION of central portion is also roughly even.
Can obtain CONCENTRATION DISTRIBUTION uniformly the reason in zone be: because the luminous irradiation area that causes of red, green, blue or green ternary LED is as being above one that is limited in basically each area I-IV from Figure 11 a and 11b are clear that.Much less this is owing in order to make pointing direction and optical axis L corresponding to red, green, the blue or green ternary LED of each area I~IV intersect the cause that LED is tilted.
Even also can be as making CONCENTRATION DISTRIBUTION even basically shown in Figure 11 a and the 11b at sensitized paper 8 central portions by luminous quantity or the angle of visibility of adjusting LED11R, 11G corresponding to each area I-IV, 11B.
Therefore, one of at least, it is regional uniformly just can to obtain CONCENTRATION DISTRIBUTION on sensitized paper 8 on a large scale in the luminous quantity by adjusting LED11R, 11G corresponding to each area I-IV, 11B, angle of visibility, inclination, the wavelength.The result can judge easily that irregular colour is even and carry out the even adjustment of irregular colour.
In addition, under the little situation in above-mentioned inclination angle,, preferably make above-mentioned inclination angle big because can unconspicuous hot spot occur on a small quantity.
Even in photo printing machine 1 of the present invention only by 12 LED for constituting LED group 11, shown in Figure 11 a and 11b, also can make the CONCENTRATION DISTRIBUTION of printing area of sensitized paper 8 even.The result can make the LED number that needs control reduce, and by briliancy or the fluorescent lifetime of controlling each LED the even correction of the even irregular colour of density unevenness is carried out easily.
And, even use, also can be limited in this effect of the present invention of zone that one of all quadrants I-IV upward and fully realizes obtaining the uniform concentration distribution relatively by the luminous irradiation area that gets of red by making, green, blue or green ternary LED than narrow (for example angle of visibility is below the 45 °) LED of LEG directive property that is used for having now light source.The result can make the diffusion rate of diffusing panel 13 reduce too, thereby can suppress the light loss of LED group 11.Even therefore the number of the LED of formation LED group 11 is few, can not cause the problem that the time shutter increases yet.
Though be to utilize LED in the present embodiment, also can utilize semiconductor laser etc. as light-emitting component as light-emitting component.

Embodiment 4
Below with reference to Figure 20 to Figure 29 an alternative embodiment of the invention is described, its explanation is represented and omitted to the parts that the parts among all and the embodiment 1 to 3 have same function with same label.
As shown in figure 21, the negative scanner 51 of present embodiment be with rayed on the negative film 59 of record original image and measure the parts of above-mentioned light, be connected with digital printer 53 by personal computer 52 (robot calculator), whereby the digital printing system of its whole formation.
Home computer 52 has main frame 52a, monitor 52b and keyboard 52c.(see that the signal that Figure 22 a) exports inputs to main frame 52a from the aftermentioned photometric measurer 55 of negative scanner 51.Image color distribution by the photometry acquisition of photometric measurer 55 is presented on the monitor 52b according to above-mentioned signal.Above-mentioned image is the image of the original image of corresponding record on negative film 59.Keyboard 52c is used to adjust light source portion 54 described later for operator's input (to see Figure 22 luminous quantity a), the parts of the indication of briliancy and fluorescent lifetime etc.
So behind the indication processing editing of view data basis by negative scanner 51 acquisitions, export printing as image from digital printer 53 by keyboard 52c input.
Negative scanner 51 is equipped with light source portion 54 and photometric measurer 55 shown in Figure 22 a.Light source portion 54 is that its details will be described later with the parts of rayed on negative film 59.
Photometric measurer 55 is the parts from the light of light source portion 54 that measure to see through negative film 59, forms by objective lens 55a with as CCD (charge-coupled image sensor) 55b (light-measuring mechanism) of imaging apparatus.Objective lens 55a can move along the optical axis L direction, with above-mentioned smooth imaging on CCD 55b.This objective lens 55a is provided with diaphragm 55c (seeing Figure 20), so that suitably be adjusted at the incident light quantity on the CCD 55b.CCD 55b is equipped with a plurality of photo detectors, by each photo detector the electric signal of corresponding light income is exported to personal computer 52.
Light path upper edge between light source portion 54 and photometric measurer 55 is provided with level crossing tunnel 56 in turn from the exit direction of light source portion 54 beginnings, collector lens 57 and ANM (the negative automatically cover of covering) 58.
Level crossing tunnel 56 is trapezoidal tubes of four ribs that inner face forms mirror, has lead the expeditiously function of negative film 59 of the light that light source portion 54 is sent.The upper bottom portion in level crossing tunnel 56 is positioned near the ANM 58, fixedly installs collector lens 57 between this upper bottom portion and ANM 58, the light that penetrates from level crossing tunnel 56 is converged with ANM 58 join on the negative film of carrying 59.Can improve the utilization factor of above-mentioned light whereby, make light loss very little.Under the situation of utilizing collector lens 57, consider the position relation and the focal length of objective lens 55a and collector lens 57, determine the position of light source portion 54 according to the design of light collecting light source.
Except that using collector lens 57, also can be by make light optically focused with for example concave mirror from light source portion 54.But the configuration of following in this case, concave mirror can make the layout of optical system become very complicated.Therefore by using collector lens 57, can make optical system structure simple as light collecting device.
ANM 58 is by negative film 59 automatic transport of conveying cylinder 60a, the 60b clamping assembly on the assigned position in the light path.
Above-mentioned each component parts is housed in the support body 51a of the negative scanner 51 shown in Figure 22 b.And negative film 59 inserts a mouthful 51b insertion from the egative film that is arranged on the support body 51a.
Below to the details of light source portion 54 with reference to Figure 20, Figure 23 a, Figure 23 b to Figure 26 describes.
Figure 23 b is the exploded perspective view of expression negative scanner 51 inside.In with figure, for convenience of description, omit the diagram in level crossing tunnel 56.And being CCD 55b sensitive surface among Figure 23 b, Figure 23 a cuts apart 4 parts enlarged drawing.
Shown in Figure 23 b, light source portion 54 is made up of with the 54b of secondary light source portion (light aligning gear, secondary light source) that forms on the substrate different with the first light source portion 54a the first light source portion 54a (first light source).
The first light source portion 54a can move with the optical axis L parallel direction according to the size of the reception optical range of CCD 55b, and the light (light of optically focused) of photometric measurer 55 is incided in main simultaneously emission by above-mentioned jog (defect part) position in addition of negative film 59.And the 54b of secondary light source portion becomes the frame shape, is formed on the periphery of the first light source 54a, mainly is that emission is by inciding the light (diffused light) on the photometric measurer 55 at the jog that forms on the negative film 59.The following describes each structure of the first light source portion 54a and the 54b of secondary light source portion.
The first light source portion 54a comprises shown in Figure 24 a and Figure 24 b: by the LED group 61 that a plurality of LED (light-emitting component) form, the LED substrate 62 and the diffusing panel 63 (seeing Figure 23 b) of fixed L ED group 61.
LED group 61 a plurality of LED61R, 61G, 61B by the light of launching red, green and cyan respectively constitute.Be that LED61R, 61G, 61B have mutually different dichroism.Control by not shown control part, so that LED61R, 61G, 61B energized when scanning negative film 59, outage when not scanning, the back will be described LED and organize 61.
On the LED of LED substrate 62 fixation side surface, post reflectance coating, so that can reduce the light loss of the light of emission from LED group 61.
Promptly organize the major part of 61 light of launching from its head ejaculation, simultaneously almost all along penetrating to photometric measurer 55 directions from LED.Certainly the light that also exists micro-head to penetrate to LED substrate 62 sides from LED61R, 61G, 61B.Therefore, can make of the direction reflection of the light of directive LED substrate 62 sides by reflectance coating is set on LED substrate 62 surfaces, thereby the light quantity towards photometric measurer 55 directions is increased to photometric measurer 55.Therefore can effectively utilize the light that LED group 61 penetrates, the result can reduce the light loss of emergent light.
Diffusing panel 63 is the frosted glass of the roughness that for example roughly can with the naked eye have an X-rayed, is configured near each head of LED group 61.In the present embodiment, the employing angle of visibility is LED61R, 61G, the 61B below 45 °, makes from the suitable diffusion of the light of LED61R, 61G, 61B by diffusing panel 63.If adopt LED61R, 61G, 61B, then diffusing panel 63 can be set with suitable angle of visibility (for example about 180 °).
In addition, though do not illustrate in the drawings, also can LED organize 61 with diffusing panel 63 between light path in the diaphragm of the opening with corresponding each LED61R, 61G, 61B is set.Can suitably adjust the angle of visibility of each LED61R, 61G, 61B by the diaphragm that in above-mentioned light path, suitably disposes opening, thereby can make the image color that obtains by photometric measurer 55 distribute more even with regulation internal diameter.
Also can be by on each of each LED61R, 61G, 61B, the variable diaphragm of opening internal diameter being set, so that by adjusting above-mentioned openings of sizes, adjust the angle of visibility of each LED61R, 61G, 61B, so just can replace the diaphragm of selectivity insertion regulation in above-mentioned light path.
Describe LED group 61 below in detail.
Figure 25 a is the stereographic map that takes off the first light source portion 54a of diffusing panel 63 in Figure 23 b.And Figure 25 b is the planimetric map of the above-mentioned first light source portion 54a.When LED substrate 62 being divided into four quadrants of the first~the four-quadrant in the figure, establishing the LED that belongs to first quartile is LED61R 1, 61G 1, 61B 1, the LED that belongs to second quadrant is LED61R 2, 61G 2, 61B 2, the LED that belongs to third quadrant is LED61R 3, 61G 3, 61B 3, belonging to four-quadrant LED is LED61R 4, 61G 4, 61B 4
Shown in Figure 25 b, near the central authorities of LED group 61, the LED of every kind of color similar number amounts to 12 of intensive configurations.More particularly, constitute four LED61R of LED group 61 1~R 4Be configured under the state that joins near the center of LED substrate 62, and with LED61R 1-R 4Point symmetry under the state (in other words the optical axis L of objective lens 55a is symmetrical relatively) four LED61G of configuration join 1~G 4, four LED61B of point symmetry ground configuration simultaneously 1~B 4Make LED61R whereby 1, 61G 1, 61B 1Three form one group, and remaining LED also forms one group by 3 in every kind of color, therefore amounts to by four groups of LED to constitute LED group 61.
Briliancy one fluorescent lifetime ratio regularly is set at for example LED61B: LED61G: LED61R=1 in each LED61R, 61G, 61B: 2: 5~6.By making each LED61R, 61G, 61B luminous in such ratio, can more serve as a contrast the least sufficient ruddiness of common light quantity, can carry out good photometry as a whole.
Above-mentioned in addition ratio also can be used as fluorescent lifetime one luminance ratio regularly.Therefore the LED number of LED group 61 is not subjected to 12 qualifications in the present embodiment, if take into account briliancy that configuration space makes green grass or young crops, green, red LED of all kinds and fluorescent lifetime long-pendingly satisfy above-mentioned 1: 2: 5~6 requirement and definite just passable.
Each LED61R, 61G, the relative optical axis L tilt angle theta of 61B are provided with, so that it points to optical axis L.With Figure 26 this point is described.
Figure 26 represents only to select for example LED61R of third quadrant 3, 61G 3, 61B 3Stereographic map.By the projecting plane X among this figure as can be known, 61G 3, 61B 3The relative optical axis L of difference direction tilt angle theta in face 1Equally, by the vertical projecting plane Y of above-mentioned relatively projecting plane X as can be known, 61R 3, 61G 3The relative optical axis L of difference direction tilt angle theta in face 2, also can make angle θ 1=angle θ 2
Though do not illustrate among the figure, remaining first, second with four-quadrant LED61R, 61G, 61B also with above-mentioned the same.In addition, above-mentioned angle θ, θ 1, θ 2Be being subjected to various conditions such as optical range, sensitized paper size and setting in the scope about 0~30 ° of the kind (focal length, aperture etc.) that to consider the lens in optical system, used, CCD 55b.
Like this, by making the relative optical axis L tilted configuration of each LED, can determine rayed zone in CCD 55b to every ternary LED61R, 61G, 61B.In the present embodiment, the zone of the rayed in CCD 55b becomes relative position relation with the first~the four-quadrant LED61R, 61G, 61B.
Specifically, from the LED61R of first quartile 1, 61G 1, 61B 1Light be radiated in the area I among the CCD 55b shown in Figure 23 a by collector lens 57, negative film 59 and objective lens 55a.And in the figure, area I be in CCD 55b when seeing with object lens 55a opposition side upper right zone.Equally, from the LED61R of second quadrant 2, 61G 2, 61B 2The area I I of rayed in CCD 55b in, from the LED61R of third quadrant 3, 61G 3, 61B 3The area I II of rayed in CCD 55b in, from four-quadrant LED61R 4, 61G 4, 61B 4The area I V of rayed in CCD 55b in.And area I I~IV rotates the zone that is respectively formed at the CCD 55b from seeing from the area I inhour with object lens 55a opposition side.
Even therefore in optical system, produce aberration etc., ejaculation light from the first light source portion 54a also can shine on the neighboring area of CCD 55b really, so need not to improve for example at the deficiency in light quantity of CCD 55b neighboring area in order to proofread and correct that the diffusion rate of diffusing panel 63 makes LED61R, 61G, the diffusion exceedingly of the light of 61B.The control that the result needn't make the fluorescent lifetime of LED61R, 61G, 61B prolong or improve glorious degrees in order to compensate the light loss that is caused by light diffusion.
In addition, by making LED61R, 61G, the relative optical axis L inclination of 61B predetermined angular θ configuration, on the sensitive surface of CCD 55b, just can not occur and each LED61R, 61G, the man-to-man hot spot of 61B.The result can suppress the inhomogeneous of light source to a certain extent, thereby same as described above, there is no need to make from the excessive diffusion of the light of LED61R, 61G, 61B.And so-called above-mentioned light source inhomogeneous just is meant that concentration and irregular colour on the sensitive surface of CCD55b are even.Therefore by making LED61R, 61G, the relative optical axis L inclination of 61B predetermined angular θ configuration just can easily adjust the inhomogeneous of light source.
In addition, during manufacturing, for example can in the step that each LED61R, 61G, 61B is fixed on the LED substrate 62, suitably adjust the inclination angle of each LED61R, 61G, 61B.Above-mentioned again inclination angle adjusts above-mentioned leg curvature ormal weight after can being fixed on the LED substrate 62 by the shank at each LED61R, the 61G that for example will be made of tinsel, 61B.
Also can equip the variable pitch mechanism at the inclination angle that can adjust each LED61R, 61G, 61B arbitrarily, will explanation in embodiment 5 described later about this example.
Have the first light source portion 54a of this spline structure, CCD 55b is subjected to optical range more little, just the closer to negative film 59 configuration, and CCD 55b be subjected to optical range big more, just more away from negative film 59 configurations.This is owing to need make the incident angle that is incident on the incident light on the negative film 59 cause that changed by optical range according to CCD 55b.Promptly when by making the first light source portion 54a near negative film 59 when the incident angle of the incident light on negative film 59 is diminished, the optical range that is subjected to of CCD 55b just diminishes.And when when making the first light source portion 54a make the incident angle that is incident on the incident light on the negative film 59 become big away from negative film 59, the optical range that is subjected to of CCD55b just becomes big.Also with thereafter the size from the photograph of digital printer 53 outputs is corresponding for the optical range that is subjected to of CCD 55b in addition.
Like this by the first light source portion 54a being advanced on optical axis L or retreating, the change that is subjected to optical range that both can infinitely corresponding CCD 55b also can be infinitely corresponding with the phase paper size.In this case, because the first light source portion 54a and the 54b of secondary light source portion independently are set,, the degree of freedom of design is enlarged so can finish best optical design.
The 54b of secondary light source portion comprises the LED group of being made up of a plurality of LED (light-emitting component) 64, the LED substrate 65 and the diffusing panel 66 (seeing Figure 23 b) of fixed L ED group 64 shown in Figure 24 a and 24b.
LED group is 64 red, green by launching respectively, a plurality of LED64R, the 64G of cyan light, 64B constitute, and promptly LED64R, 64G, 64B have the dichroism that differs from one another.LED64R, 64G, 64B are by not shown control part control, and energising when scanning negative film 59 is cut off the power supply when not scanning.Detailed structure about LED group 64 will be described later.
Be formed with at the central portion of LED substrate 65 and make the rectangular aperture that passes through from the light former state of the first light source portion 54a.Thereby LED substrate 65 is formed centrally ring-type in optical axis L being, LED64R, the 64G, the 64B that are fixed on the LED substrate 65 also are configured to ring-type.In addition, post on the LED of the LED substrate 65 fixation side surface be arranged on LED substrate 62 on identical reflectance coating so that can reduce the light loss of the light of emission from LED group 64.
Diffusing panel 66 for example is the frosted glass with roughness of the big activation of naked eyes perspective, and it is configured near each head of LED group 64.Make the rectangular aperture that passes through from the light former state of the first light source portion 54a and be formed with at the central portion of diffusing panel 66.
Adopting angle of visibility in the present embodiment is LED64R, 64G, 64B below 45 °, so that make light from LED64R, 64G, 64B by diffusing panel 66 suitable diffusions.In addition, have LED64R, 64G, the 64B of suitable angle of visibility (for example about 180 °), then there is no need to be provided with diffusing panel 66 as employing.
Though do not illustrate among the figure, also can be by in the light path between LED group 64 and diffusing panel 66 angle of visibility of above-mentioned diaphragm with each LED64R of suitable adjustment, 64G, 64B being set.
The variable diaphragm of internal diameter of peristome also can be set on each LED64R, 64G, 64B, so that adjust the angle of visibility of each LED64R, 64G, 64B, so just can replace in above-mentioned light path, optionally inserting the diaphragm of regulation by adjusting above-mentioned opening.
The following describes the detailed structure of LED group 64.
Pointing direction and the optical axis L of LED64R, 64G, 64B are installed in LED61R, 61G, 64B on the LED substrate 65 abreast.This is owing to can make the diffused lights of LED group 64 emissions be incident on cause on the negative film 59 expeditiously by level crossing tunnel 56 and collector lens 57.With each LED is installed on the substrate than adopting said method to have the manufacturing process of making and the more simple advantage of manufacturing management at the inclination angle in accordance with regulations.Certainly each LED is installed on the substrate with the inclination angle of stipulating the present invention is not had any obstacle yet.
The configuration of LED64R, 64G, 64B is as follows.Shown in Figure 24 a, the number of the LED of LED group 64 is about 10 times of LED number of the LED group 61 of the first light source 54a, for example is 120.For for four limits of the rectangular aperture of LED substrate 65, each limit divides four sections to pile up 30 LED of configuration.
Promptly on ground floor, the second layer, respectively dispose 10 LED, 8 LED of configuration on the 3rd layer, 2 LED of configuration on the 4th layer.By so a plurality of LED being configured on the multilayer, not only can prevent to obtain the image of the defective etc. of corresponding negative film 59 by photometric measurer 55, but also can adjust the photo hardness that obtains after the photometry easily, in other words can adjust the vividness of the degree of representing that the image of printing is clear or bluring easily.
The individual percentage of LED64R, 64G, 64B can make the LED64R of deficiency in light quantity more slightly, and the LED64B that photonasty is strong lacks slightly, and LED64G is set between preceding two kinds of LED.But to luminous quantity, control so that the long-pending formation of glorious degrees and fluorescent lifetime is red: green: the ratio of cyan is 5~6: 2: 1.By making each LED luminous with such ratio, can replenish the often the most not enough red light of light quantity, can carry out correct photometry as a whole.
About the position relation of LED64R, 64G, 64B, can near optical axis L, put LED64R by polygamy, make LED64B relatively from the optical axis L farthest.Therefore, one side LED64B is configured to four layers facing to the rectangular aperture on the LED substrate 65.
Like this, in the present invention, owing to use LED as constituting the first light source portion 54a, the light-emitting component of the 54b of secondary light source portion is so can realize following effect and effect.
1) the present invention need be under the situation of making light-emitting component with Halogen lamp LED necessary cooling fan, absorb the hot line light filter, the light modulation light filter, cut-off filter etc., thus can simplify the structure of light source portion 54.In addition, because there is not cooling fan, thus dust on every side can be blown into optical system, thus can carry out the high-quality photometry.
2) because dichroism is stable, and direct supply can be with the simple power supply on the control circuit board that voltage is added in IC (integrated circuit).Therefore direct supply that can be special, thus can prevent that locking apparatus maximizes.In addition, because dichroism is stable, so be easy to by ON/OFF control carrying out light modulation management to each LED.
3) owing to each LED being carried out ON/OFF control, so when unnecessary, can not light LED.Therefore compare the electric power that can reduce consumption significantly with the situation of utilizing Halogen lamp LED.In addition, under the situation of not photometry, owing to disconnect LED, so there is no need between CCD 55b and light source portion 54, tripper to be set.The result reduces component count, negative scanner 51 simple in structure.
4) the light quantity difference of optical axis and periphery thereof does not have Halogen lamp LED so big.Therefore than the light loss during as light source reduces with Halogen lamp LED.
5) because each LED is carried out ON/OFF control, so need not make LED continue to light when above reaching requirement.Therefore even under the more situation of photometry number of times, also can prevent by the heating of each LED damage to negative film 59.
6) because the dichroism of each LED is mutually different, so there is no need between CCD 55b, to dispose the color filter of R, G, B.Thereby make the simple in structure of light source portion 54.
Relative position relation to the optical axis L of the first light source portion 54a and the 54b of secondary light source portion describes below.
Figure 20 shows zone and the inaccessible zone that directly reaches CCD 55b in the exposure system that is made of collector lens 57, negative film 59, objective lens 55a and CCD 55b from the light of light source.Certainly, the first light source portion 54a and the 54b of secondary light source portion are configured on the zone with objective lens 55a opposition side as boundary with collector lens 57, and can not be configured in collector lens 57 in the zone of objective lens 55a side.
Light source light can not directly reach the zone of any point of CCD 55b even the hatched example areas of Figure 20 shows configuration, is clipped in zone that the oblique line around the optical axis L in the hatched example areas of Figure 20 do not enter and is if configuration light source then light necessarily directly reach the zone on the point in CCD 55b somewhere.Light on hatched example areas and no hatched example areas boundary line arrives the end of CCD55b by the end of negative film 59.
Therefore, the first light source portion 54a is a center configuration with the optical axis L in the zone that above-mentioned oblique line does not enter, the position relation of setting the first light source portion 54a and the 54b of secondary light source portion on the above-mentioned hatched example areas for the above-mentioned secondary light source 54b of portion is configured in, this point is a key character of the present invention.Therefore suppose that negative film 59 is normal, when for example lighting the first light source portion 54a and the 54b of secondary light source portion simultaneously, the emission light of the 54b of secondary light source portion does not reach CCD 55b certainly.
Therefore, the first light source portion 54a and the 54b of secondary light source portion that have such position relation by utilization, negative film 59 defectiveness for example having under the situation of shallow defective on the negative film 59, though also can obtain not have the superior images of defect image on the image of printing.The following describes its principle.
The optically focused light vertical incidence that the expression of Figure 27 a pattern ground is penetrated from the first light source portion 54a sees through the situation of the vertical section of the negative film 59 that has groove shape defective 59a.As shown in the drawing, be incident on light a3, the a4 on the defective 59a owing to reflected, and can not reach the CCD 55b of the light exit side that is configured in negative film 59 by defective 59a.Be incident on that light a1, a2, a5, the a6 on the position directly sees through negative film 59 and arrive on the CCD 55b beyond the defective 59a.
The diffused light that the expression of Figure 27 b pattern ground is penetrated from the 54b of secondary light source portion also sees through the state of the vertical section of negative film 59 from oblique upper incident.As shown in the figure, be incident on defective 59a light in addition owing to directly can not arrive on the CCD 55b through negative film 59.Comprise in the light on the lateral incline on the defective 59a through the defective 59a refraction vertical light a11 that penetrates back arrival CCD 55b from the face of the exiting side of negative film 59 and be incident on.
Equally, shown in Figure 27 c, under the situation that the diffused light that penetrates from the 54b of secondary light source portion on the vertical section of negative film 59 incident below tiltedly sees through, be incident on and comprise the light a12 that arrives CCD 55b through defective 59a refraction after the outgoing lateral vertical outgoing of negative film 59 under the defective 59a in the light on the lateral incline.
Promptly because the light a11, the a12 that arrive on the CCD 55b expose the position of the defective 59a imaging on CCD 55b, so in by the image of CCD 55b photometry, can not be short of the part of corresponding defective 59a.
Therefore, shown in Figure 27 d, penetrate imaging at light a1, a2 on the CCD 55b, a5, a6 and penetrate the light a11, the a12 that after the concavo-convex anomalous refraction of the defective 59a of negative film 59 etc., arrive on the CCD 55b from the 54b of secondary light source portion and lump together and make CCD 55b exposure by making, can prevent that resemble (for example blank) of corresponding defective 59a from forming on the sensitive surface of CCD 55b without negative film 59 anomalous refractions from the first light source portion 54a.
In other words, we can say that it is in order to compensate with concavo-convex upset imaging light paths such as defective 59a because the concavo-convex upset imaging light paths such as defective 59a on the negative film 59 form this class deficiency in light quantity of defect picture on CCD 55b conversely that the 54b of secondary light source portion is set.
At this moment, as the position of the first light source portion 54a and the 54b of secondary light source portion relation, as illustrate, the first light source portion 54a is configured on the position of optical axis L, does not directly reach zone on the CCD 55b and the 54b of secondary light source portion is disposed light, and this is important.Therefore, do not have under the concavo-convex situation such as defective 59a, the 54b of secondary light source portion is not being used for the defective of eliminating negative film 59 following of the influential condition of the uneven correction of the light source of the first light source portion 54a at negative film 59.
In addition, in a part that from the light of first light source portion 54a ejaculation, also contains sometimes through the light of concavo-convex arrival CCD 55b such as defective 59a.Therefore the luminous quantity that is recorded among the CCD 55b preferably respectively being determined by the briliancy of each LED of the first light source portion 54a and the 54b of secondary light source portion and fluorescent lifetime etc. for the concavo-convex picture that does not make defective 59a etc. carries out Optimal Control.
Below to being described in the superficial situation of the defective that forms on the negative film 59 or the integrated operation of the digital printing system under the flawless situation.
When light source portion 54 (the first light source portion 54a and the 54b of secondary light source portion) when lighting, the light that penetrates from light source portion 54 is incident on the collector lens 57 by the inside in level crossing tunnel 56.The light that incides collector lens 57 is arrived on the negative film of being carried by ANM58 59 by collector lens 57 optically focused.Because the 54b of secondary light source portion is by above-mentioned such setting,, can not sees through negative film 59 from the light of the 54b of secondary light source portion and arrive photometric measurers 55 so do not have at negative film 59 under the normal condition of defective etc.And under the situation that forms superficial defective on the negative film 59, the light from the first light source portion 54a that sees through the position beyond the defective 59a reaches photometric measurer 55, simultaneously, arrives photometric measurer 55 from the light of the 54b of secondary light source portion of defective 59a refraction.
Therefore, in photometric measurer 55, be recorded in the influence that original image on the negative film 59 is not subjected to defective 59a, by objective lens 55a imaging on the sensitive surface of CCD 55b.That is, can only not make and be formed on the locational image of defective 59a and do not arrive photometric measurer 55.Then, when each photo detector of CCD 55b flows to the main frame 52a of personal computer 52 with the electric signal of corresponding light income, on monitor 52b, show the CONCENTRATION DISTRIBUTION of the image of imaging on the sensitive surface of CCD 55b according to above-mentioned signal.The operator adjusts luminous quantity, briliancy and the fluorescent lifetime etc. of light source portion 54 by operation keyboard 52c, so that adjust the inhomogeneous of light source.Thereafter from printing the image that output is read by negative scanner 51 by negative scanner 51 and the digital printer 53 that personal computer 52 is connected.
Like this, the first light source portion 54a and the 54b both of secondary light source portion are lighted, the light of optically focused and diffused light are shone with proper proportion, even when forming superficial defective 59a on negative film 59, the picture of corresponding defective 59a does not occur in scan image yet.So on CCD 55b, can obtain not have the image of defect image.
Below the correspondence under the situation that forms for example dark defective on the negative film 59 is described.
Under the dark situation of the defective 59a of negative film 59, even the light of optically focused and diffused light are shone with proper proportion, the picture of corresponding above-mentioned defective 59a also can become and blankly occurs in scan image.So above-mentioned blank of essential reparation in this case.
Personal computer 52 can not judge that the blank in scan image is the defect image of corresponding defective 59a or is exactly the part of the formal scan image of the original image of corresponding record on negative film 59 originally.
Under the dark situation of the defective 59a of negative film 59, as follows the defective in the scan image is eliminated and carried out digital processing.
At first only light the 54b of secondary light source portion, make CCD 55b carry out photometry (first handles), whereby the defect image of corresponding defective 59a is imaged on the sensitive surface of CCD 55b the light that obtains by the defective 59a shown in Figure 27 b and the 27c.Then, CCD 55b is by the signal of each photo detector to the corresponding light income of personal computer 52 transmissions, when only defect image being imported personal computer 52, by the position of the above-mentioned defect image of personal computer 52 identifications.
Then make the first light source portion 54a and the 54b both of secondary light source portion light (second handles).Make defect image (blank) and the corresponding defective 59a zero defect image imaging on the sensitive surface of CCD 55b at position in addition of the defective 59a shown in the corresponding diagram 27d.Then, the signal that sends by CCD 55b inputs to personal computer 52 with these scan images.
Because the position of defective is identified, so make the concentration increase of the position of above-mentioned defect image make it to meet the processing (the 3rd handles) of image color by personal computer 52.Concentration adjustment in this case can be by for example carrying out at the luminous quantity of the photometric quantity increase secondary light source 54b of portion of photometric measurer 55 according to the light from the 54b of secondary light source portion.This processing also can see that monitor 52b limit manually carries out by keyboard 52c by the operator limit.Also the software that can be consistent with near the concentration of the position concentration that makes defect image and the defect image itself is carried out automatically by personal computer 52.Like this, the view data that defect image is corrected flows to digital printer 53, as the printing image output of zero defect image.
By such digital processing,, also can pass through defect recognition image, only repair-deficiency image even the defective of defective 59a is darker.Thereby can obtain the high-quality photos of zero defect image.
Also can be recorded on the recording medium shown in Figure 28 67 (for example CD-ROM), with of the existence of this recording medium 67 by personal computer 52 automatic defect recognition 59a in the program of in advance personal computer 52 being carried out above-mentioned first processing.That is, in this case, personal computer 52 makes the 54b of secondary light source portion luminous according to the program of record in recording medium 67, makes the light of CCD 55b mensuration by the defective acquisition of negative film 59.By the photometry result on CCD 55b is flowed to personal computer 52, be identified in automatically on the negative film 59 by personal computer 52 and have defective part.
Also can replace being provided with the luminous 54b of secondary light source portion of nature by the mechanism that produces after the emergent light reflection make the first light source portion 54a or the diffusion from random direction is incident on the light on the negative film 59 is set.
Negative scanner 51 of the present invention is compared with use the photo printing brush machine of the prior art of LED in light source, the number of the LED that constitutes the first light source portion 54a is reduced, its result can have the uneven effect of easy adjustment light source and eliminate the effect of defective, describes with regard to these advantages below.
Be illustrated in to Figure 29 pattern and make that the first light source portion 54a is luminous to carry out the CONCENTRATION DISTRIBUTION on the sensitive surface of CCD 55b under the photometry situation.Four roundlets representing with C1~C4 are by the luminous the highest zone of concentration that forms in the heart in each irradiation of above-mentioned red, green, blue or green ternary LED.Therefore above-mentioned C1~C4 is called extremal region.It is far away more to leave extremal region C1~C4, and illumination is low more, so concentration slowly descends.That is, it is big more that each center of corresponding extremal region C1~C4 demonstrates radius, and concentration is low more.
Extremal region C1 with area I is a plurality of concentric circless at center, shows for example LED61R shown in Figure 25 b 1, 61G 1, 61B 1Luminous CONCENTRATION DISTRIBUTION.Equally, be that a plurality of concentric circless at center show LED61R with the extremal region C2 of area I I 2, 61G 2, 61B 2Luminous CONCENTRATION DISTRIBUTION, be a plurality of concentric circless at center with the extremal region C3 of area I II, show LED61R 3, 61G 3, 61B 3Luminous CONCENTRATION DISTRIBUTION, be that a plurality of concentric circless at center show LED61R with the extremal region C4 of area I V 4, 61G 4, 61B 4Luminous CONCENTRATION DISTRIBUTION.
As shown in figure 29, each area I-IV of CCD 55b is divided in the X-axis of initial point O quadrature and Y-axis.Like this, obviously the closer to the zone of initial point O, CONCENTRATION DISTRIBUTION is even more.Therefore when actual photometry, in order near near the uniform zone of CONCENTRATION DISTRIBUTION around the initial point O, to carry out photometry, promptly for unfavorable with carrying out photometry near the extremal region C1-C4, and the inclination angle of setting LED and the distance between objective lens 55a and CCD 55b.Can obtain CONCENTRATION DISTRIBUTION zone uniformly like this, this is owing to be limited in cause among each area I-IV one as shown in Figure 29 relatively based on luminous irradiation area red, green, blue or green ternary LED.This obviously is because LED tilts to make red, green, the blue or green ternary LED pointing direction of corresponding each area I-IV and the cause that optical axis L intersects.
Like this, even only constitute the LED group 61 of the first light source portion 54a, also can make the CONCENTRATION DISTRIBUTION of the photometry region among the CCD 55b even by 12 LED according to negative scanner 51 of the present invention.Therefore, because the number of the LED that should control is also passable less, so be easy to carry out the uneven correction of light source by briliancy and the fluorescent lifetime of controlling each LED.
Even use LED with directive property (for example angle of visibility is below 45 °) narrower than the LED that in existing light source, uses, by being limited in relatively based on luminous irradiated region red, green, blue or green ternary LED among each area I-IV one, also can obtain the zone of uniform CONCENTRATION DISTRIBUTION, thereby can give full play to effect of the present invention.Its result owing to can obtain this result too when the diffusion rate of diffusing panel 63 is hanged down, can suppress the light loss of LED group 61.Like this, even the number of the LED of formation LED group 61 is few, can not cause the problem that the time shutter is elongated yet.
Because each area I that red, green, blue or green ternary LED is corresponding CCD 55b-IV installs, so can freely change Y (Huang), M (fuchsin), C (blue green) concentration among each area I-IV by the luminous quantity that changes the LED of all kinds in each group.
Like this, structure according to the first light source portion 54a of the present invention, with the prior art of LED and optical axis configured in parallel is different, unnecessary in order to improve the effect of eliminating defective, and it is inhomogeneous and the high diffusing panel of diffusion rate is set in the front of a plurality of LED not occur light source when photometry.In addition under the situation that LED and optical axis are provided with abreast, because the influences such as aberration that design of Optical System takes place, make the relative middle body deficiency of light quantity of the marginal portion of CCD55b, from and cause the essential control trouble that increases the LED luminous quantity of irradiation CCD55b marginal portion, can not produce this problem according to the structure of the first light source portion 54a of the present invention.
Embodiment 5
Below with reference to Figure 30 a and Figure 30 b explanation another embodiment of the present invention.The situation of structure that just the first light source portion 54a of explanation is equipped with the inclination angle of each LED that can continuously change LED group 61 in embodiment 4 describes in the present embodiment.Therefore all parts identical with the component function of use among the embodiment 4 are all represented with same parts label, and omit its explanation.

Cam 75 be arranged to above-mentioned each minute cutting board 62a~62d on LED group 61 those sides are not set face contact.This cam 75 can rotate around fulcrum 76, follows the pulling force of this rotation antagonistic spring 73 that each minute cutting board 62a~62d is rotated around rotating shaft 71.The rotation of cam 75 is by not shown control part control.Follow rotation each minute cutting board 62a of cam 75~62d to rotate like this, the inclination angle that the result can organize LED each LED of 61 is adjusted on the desired angle.
The rotation of each minute cutting board 62a~62d is not limited to as mentioned above to realize by the rotation of cam 75 grades, and to make each minute cutting board 62a~62d be the structure that continuous variable rotates just passable as long as adopt.
Like this, can adjust CONCENTRATION DISTRIBUTION in the sensitive surface of CCD 55b for example shown in Figure 29 by constituting by each zone of all quadrants of corresponding LED group 61 to mechanism's (pointing direction adjusting mechanism) at the inclination angle of each LED of each quadrant variable L ED group 61.The extreme point of above-mentioned CONCENTRATION DISTRIBUTION can be freely changed whereby, thereby the inhomogeneous of light source can be adjusted more easily.
Make the structure of present embodiment of the variable pitch of each LED, can certainly be useful on the electronic photo input media of the photograph printing device of the above embodiments 1 and 2 and embodiment 3.

In the present embodiment, though because LED group 81,82 is formed on the same substrate 83 together LED group 81 is moved separately along the optical axis L direction, also can resemble the printing that is subjected to optical range of carrying out corresponding CCD 55b the embodiment 4 by making light source portion 54 ' itself move along the optical axis L direction.
Further describe the configuration of LED group 81 below.
The LED that has illustrated in Figure 32 b from diffusing panel 84 sides 32a with the aid of pictures organizes 81 o'clock planimetric map.As shown in the figure, LED group is 81 red, green by penetrating respectively, a plurality of LED81R, 81G, the 81B of the light of cyan constitute, that is, the corresponding dichroism of all kinds of these LED is different.
At this, for convenience of description, LED81R, 81G, 81B are defined as follows.Establishing the LED that belongs to first quartile in Figure 32 b is LED81R 1, 81G 1, 81B 1, the LED that belongs to second quadrant is LED81R 2, 81G 2, 81B 2, the LED that belongs to third quadrant is LED81R 3, 81G 3, 81B 3, belonging to four-quadrant LED is LED81R 4, 81G 4, 81B 4
LED81R in LED group 81,81G, the configuration of 81B is identical with the situation of the LED group of using in embodiment 4 61.That is, near the central portion of LED group 81, amount to 12 LED of intensive configuration by every kind of color equal number.More particularly, make four LED81R 1-R 1Be connected to each other under the state around the central portion and dispose, with LED81R 1~R 4Following four LED81G of connection status 1~G 4Point symmetry configuration (in other words, optical axis L is symmetrical relatively), simultaneously, four LED81B 1~B 4The point symmetry configuration.Make for example LED81R whereby 1, 81G 1, 81B 1Form one group for three, corresponding remaining LED forms one group by three in every kind of color.Therefore constitute LED group 81 by amounting to four groups of LED.
This constitutes ternary LED81R, 81G, 81B and the LED of embodiment 4 and organizes 61 identical, by tilting to be installed on the LED substrate 83 for its pointing direction and optical axis L are intersected, and corresponding installation, thereby make on its zone that mainly is radiated at this correspondence with the specific region of CCD 55b.
Specifically, shown in Figure 32 a, be that the center is divided into four area I-IV with the optical axis L with CCD 55b, from objective lens 55a opposition side, determine area I-IV from lower-left zone inhour rotation.In this case, the LED81R shown in Figure 32 b 1, 81G 1, 81B 1Correspondence is installed on the above-mentioned area I.Equally, LED81R 2, 81G 2, 81B 2Correspondence is installed on the above-mentioned area I I, LED81R 3, 81G 3, 81B 3Correspondence is installed on the above-mentioned area I II, LED81R 4, 81G 4, 81B 4Correspondence is installed on the above-mentioned area I V.
In addition, arrange alternately every 2-3 the red LED82R of emission, simultaneously, these LED82R, 82G, the relative optical axis L point symmetry of 82B are arranged, make it be configured to the square-shaped frame shape as a whole at the LED82B of LED82G that makes transmitting green and emission cyan.The individual percentage of LED82R, 82G, 82B approximately is set at 5~6 for carrying out correct photometry: 2: 1.That is to say and adopt to replenish the often the most individual percentage of the red light of easy deficiency of light quantity.
To consider this point too for LED group 81.That is, LED81R is configured in LED organizes 81 central portion, above-mentioned position is as the position in the easiest collection red light of CCD 55b.And the fluorescent lifetime briliancy fixedly the time is than with regard to red, green, the blue or green 5-6 that suitably is set at of all kinds: 2: 1.In addition, above-mentioned ratio also can be used as the luminance ratio of fluorescent lifetime fixedly the time.
LED82R, 82G, the 82B that constitutes LED group 82 situation with the LED group 64 of embodiment 4 respectively is identical, and pointing direction and optical axis L are arranged on the LED substrate 83 abreast.This is owing to can make manufacturing process and manufacturing management simple with each LED angle of inclination in accordance with regulations being installed in compare on the substrate.If but attention improves the utilization factor of light, and each LED angle of inclination in accordance with regulations is installed on the substrate.
The LED number that is configured in the LED group 81,82 is not limited by present embodiment should, can take into account to join to show the space so that the briliancy of red, green, blue or green LED of all kinds and fluorescent lifetime long-pending satisfied above-mentioned 5~6: 2: 1 requirement and deciding.
The following describes the relative position relation of 81,82 pairs of optical axis L of LED group.Figure 31 shows in the exposure system that is made of negative film 59, objective lens 55a, CCD 55b, light source portion 54 ' light directly reach zone and the inaccessible zone of CCD 55b, certainly light source 54 ' be configured on the zone with objective lens 55a opposition side as the border with negative film 59, and be not configured in the objective lens 55a side of negative film 59.
Also directly do not reach the zone of any point of CCD 55b even the hatched example areas of Figure 31 has represented to be configured light source light, and under the condition of configuration light source, must directly be reached the zone of certain point of CCD 55b by the region representation that the optical axis L oblique line on every side that the hatched example areas of Figure 31 clips does not enter.The light of advancing on the boundary line in the zone that hatched example areas and oblique line do not enter can reach the end of CCD 55b by the end of negative film 59.
LED group 81 is a center configuration with the optical axis L in the zone that above-mentioned oblique line does not enter, and concerns that for LED group 82 being configured in sets on the above-mentioned hatched example areas LED to organize 81,82 position this point is a key character of the present invention.Thereby when repair-deficiency image for example, light LED group 81,82 both, under negative film 59 normal situations, LED organizes 82 emergent light and can not reach on the CCD 55b.
Like this, even do not resemble use the embodiment 4 light source portion 54 that collector lens also can be by forming the above-mentioned such LED of configuration group 81,82 ', similarly to Example 4, though organizing the light of the optically focused of 81 outgoing from LED can be by reaching CCD 55b in the refraction of the defective of negative film 59, see through that the light of part can reach CCD 55b beyond the defective.In addition, the light at position does not reach CCD 55b beyond the defective though the diffused light of organizing 82 outgoing from LED in the defective refraction of negative film 59 and arrive on the CCD 55b, sees through.
Therefore,, be used to from the light and the diffused light this point of the optically focused of LED group 81,82 as broad as longly, also can repair with embodiment 4 the same defect recognitions or according to the defect recognition result to the image of defect image with embodiment 4 even in the present embodiment.
No matter with the light source portion among the embodiment 4 54 replace the light source portion 54 of present embodiments ', otherwise still with the structure of the light source portion 54 of the light source portion 54 ' replacement embodiment 4 of present embodiment, as long as note the allocation position of LED group, in these cases, can obtain the effect identical with the present invention.

The also following structure of photograph printing device of the present invention: a plurality of groups of being made of a plurality of light-emitting components of above-mentioned light source are formed, and in each group of above-mentioned each group, determine the rayed zone in above-mentioned photosensitive material.
According to said structure, it is even that the even irregular colour of density unevenness of photosensitive material integral body is adjusted in the adjustment of the light-emitting component of each group that can be by corresponding each rayed zone.The result can more easily adjust with irregular colour is even the photosensitive material overall density is inhomogeneous.
Photograph printing device of the present invention also is provided with the structure that makes the collective optics that the light from above-mentioned light source converges between above-mentioned light source and above-mentioned information preservation body.
According to said structure, can improve the utilization factor of source emissioning light, can reduce light loss.
The structure that the also above-mentioned collective optics of photograph printing device of the present invention is a collector lens.
According to said structure, and compare under the situation that constitutes collective optics with concave mirror for example, can make the layout of optical system simple.Thereby both can make design of Optical System easy, and can make the simple in structure of optical system again and make equipment miniaturization.
Photograph printing device of the present invention also can be that above-mentioned light-emitting component is a light emitting diode, at least one adjustable structure in the luminous quantity of above-mentioned light emitting diode, angle of visibility, inclination angle, the wavelength.
According to said structure, just extensively CONCENTRATION DISTRIBUTION of obtaining in the photosensitive material of scope ground is regional uniformly at least one in the luminous quantity by adjusting light emitting diode, angle of visibility, inclination angle, the wavelength.The result is can easier judgement irregular colour even, carries out the even adjustment of irregular colour easilier.
Electronic image input device of the present invention also comprises above-mentioned photograph printing device and to preserve the structure of the image mechanism that the light from above-mentioned light-emitting component that body obtains makes a video recording by above-mentioned information.
According to said structure, if in above-mentioned photograph printing device, replace above-mentioned photosensitive material then can directly for example print the even adjustment of the even irregular colour of density unevenness before handling according to the output of above-mentioned image mechanism with image mechanism.Promptly, if above-mentioned image mechanism for example is CCD, then because CCD is an electric signal of exporting corresponding light income by each pixel, so can be identified in the CONCENTRATION DISTRIBUTION of the light image of imaging on the CCD sensitive surface according to the detection signal of CCD.Therefore there is no need to be used for the test print that detectable concentration is inhomogeneous and irregular colour is even, its result can carry out the adjustment that density unevenness is even, irregular colour is even rapidly.
Negative scanner of the present invention also can adopt following structure, is equipped with:
With first light source of rayed on the egative film of record original image, by measuring the light-measuring mechanism of the above-mentioned original image of identification to seeing through light on the above-mentioned egative film, the light path of utilizing unusual position to cause upsets the light compensation mechanism that the deficiency in light quantity at this unusual position of above-mentioned light-measuring mechanism formation owing to there is this unusual position of upsetting the light path from above-mentioned first light source to above-mentioned light-measuring mechanism on backsheet surface is compensated.
Negative scanner of the present invention also can adopt following structure, and the above-mentioned relatively egative film of above-mentioned smooth compensation mechanism is located at the emergent light that with the zone of above-mentioned light-measuring mechanism opposition side, promptly is arranged on above-mentioned smooth compensation mechanism and sees through above-mentioned egative film and do not arrive on the zone on the above-mentioned light-measuring mechanism.
According to said structure, even light is incident on the egative film, do not arrive at this egative film of this light transmission under the situation of configuration light compensation mechanism on the zone on the light-measuring mechanism, if on egative film no abnormal position, then the light of light compensation mechanism emission does not arrive light-measuring mechanism yet; As unusual position is arranged on the egative film, then the part of the light of light compensation mechanism emission is by the arrival light-measuring mechanisms such as refraction at this unusual position.Thereby by making when the photometry first light source and light compensation mechanism simultaneously luminous, make first light source for the photometry that is recorded in the original image on the egative film, and the light compensation mechanism when only on egative film, having unusual position for preventing the use of recording exceptional position.
As a result, even also need not change the control content of first light source of adjusting because of the photometry of original image with the first light source branch light compensation mechanism that is arranged.
Negative scanner of the present invention also can adopt following structure, be that above-mentioned smooth compensation mechanism constitutes the structure that the luminous quantity of above-mentioned at least secondary light source can change arbitrarily by the secondary light source of being made up of the mutually different a plurality of light-emitting components of dichroism (for example LED).
According to said structure, can adjust the luminous quantity of each light-emitting component of secondary light source according to the degree (for example degree of depth of defective) that is formed on the unusual position on the backsheet surface for example.Thereby under the low weight situation of the degree at for example above-mentioned unusual position (situation that defective is shallow etc.), by making above-mentioned luminous quantity than lacking usually, on one side can reduce the electric power that secondary light source consumes, Yi Bian repair.And under the degree serious situation at for example above-mentioned unusual position (situation that defective is dark etc.),, can carry out the reparation of defect image effectively by making above-mentioned luminous quantity more.
Make by with the adjustment of the luminous quantity of secondary light source the time luminous quantity respective change of first light source can change the vividness of the scan image that obtains by light-measuring mechanism, promptly change the hardness of so-called photo.
Negative scanner of the present invention also can adopt following structure, be that above-mentioned first light source is made of the mutually different a plurality of light-emitting components of dichroism, this each light-emitting component is according to light being pointed to and being connected the mode that optical axis that above-mentioned first light source is connected with above-mentioned light-measuring mechanism intersects from a plurality of directions and being provided with.
According to said structure, by the pointing direction of light being set for and optical axis intersection fork, with the part of the light-emitting component of first light source and the corresponding installation in specific region from the optical axis deviation of light-measuring mechanism.That is, make the rayed that penetrates from the part of light-emitting component from the specific region of the optical axis deviation of light-measuring mechanism.In addition,, the pointing direction of light intersects, so that the corresponding relation between the specific region of the part of light-emitting component as described above and photometry element has is multiple because setting for from a plurality of directions and optical axis.
Like this, form the specific region of the intensity distributions off-centre of a plurality of irradiates lights, consequently making in the central area that is surrounded by this specific region is to form intensity distributions zone uniformly on the peripheral region of optical axis.In the uniform zone of intensity distributions, because it is even not produce the even irregular colour of density unevenness, so available such area metering.In addition, as long as set light-emitting component with the mode that optical axis intersects from a plurality of directions, even do not make light diffusing diffusing panel etc. also can form such zone basically in the light-emitting component former configuration according to the sensing of light.
Therefore, can effectively utilize the light of light-emitting component emission, can reduce light loss, so set abreast with optical axis with the pointing direction of light, the high diffusing panel of diffusion rate compared as essential existing negative scanner, can obtain both to have reduced fluorescent lifetime, prevent to write down the double effects at the unusual position of egative film again.
