Abstract

PURPOSE:To obtain a divided print photograph whose image accurately corresponds to an image of each area by overlapping a lith film on which a boundary is recorded with a picture, printing the lith film which is divided and printed, and cutting down an unnecessary part of the priphery along the cutting line where the boundary is printed. CONSTITUTION:The lith film 25 on which the boundary of each area is recorded is superposed with one frame of the photographic film 10 and set on a film holder 12. The film 25 is moved at the prescribed pitch, and an image of each area is printed on a photosensitive member 43 together with the boundary 24. When the obtained print picture is cut down along the borderline 24, the divided print photograph 57 only with the image of each area is obtained. Therefore, when a little dislocation occurs during movement of the film holder 12, the photograph of the divided print 57 accurately corresponding to the image of each area can be obtained regardless of the dislocation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for creating divided prints in which one frame is divided into a plurality of areas and each area is enlarged and printed.

[Prior Art] Instead of creating a single photograph that is a large enlargement of one frame of photographic film, one double side is divided into multiple areas and each area is enlarged on photographic paper. A method has been proposed in which one large-sized photograph is essentially created by arranging the divided printed photographs of the original image in accordance with the positions of the original images (for example, Japanese Patent Application No. 84275/1983).
. In this divisional printing, a film holder holding a photographic film is moved two-dimensionally at a predetermined pitch within a plane perpendicular to the printing optical path, thereby dividing one screen into a plurality of areas.

[Problem to be solved by the invention]

In the above-mentioned division printing, since the film boulder is divided into a plurality of areas by moving the film boulder at a predetermined pitch, it is necessary to position the film holder in two-dimensional directions with high precision. However, in reality, slight deviations occur in the feeding of the film boulder due to play in the moving means of the film holder, differences in positioning accuracy, etc. For this reason, there is a problem in that it is not possible to obtain divided print photographs of images that accurately correspond to the images of each area.

The present invention has been made to solve the above problems, and even when the feeding accuracy of the film holder etc. is not good,
To provide a method for creating a divided print photograph by which a print image accurately corresponding to an image of each divided area can be easily obtained.

[Means to solve the problem]

In order to achieve the above object, the present invention uses a lithographic film on which the boundaries of each area are recorded, overlays this lithographic film on one frame of photographic film, places it on a film holder seven times, and moves the film holder at a predetermined pitch. The image of each area and the boundary line are printed on a photosensitive material, and the resulting printed photograph is cut along the boundary line.

[Effect]

A lithographic film on which the boundary line of each area is recorded is superimposed on one frame of photographic film and set in a film holder, and this is moved at a predetermined pitch to print the image of each area together with the boundary line on the photosensitive material.

When the obtained printed photograph is cut along its boundary line, a divided printed photograph containing only the images of each area is obtained.

As a result, even if a slight deviation occurs in the movement of the film holder, a divided print photograph that accurately corresponds to the image of each area can be obtained regardless of this deviation.

By arranging the divided print photographs at positions corresponding to the original image, it is possible to create, for example, a photographic display in which each print photograph is lined up without gaps. In addition, by making the thickness of the border line correspond to the gap between each divided print photo on the photo display, even if the divided print photos are separated by a predetermined gap on the photo display, the images of the divided print photos can be easily displayed. , it is possible to accurately correspond to the image of each area regardless of the feeding accuracy of the film holder.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

In FIG. 1, white light emitted from a light source 2 is filtered through a cyan filter 3. Magenta filter 4. After passing through the yellow filter 5, it enters the diffusion box 6.

The amount of insertion of these color filters 3 to 5 into the printing optical path 8 is adjusted by the filter adjustment section 7, thereby adjusting the light quality of the printing light. The diffusion box 6 is a rectangular cylinder whose inner surface is a mirror surface, with diffusion plates attached to both ends thereof, and sufficiently diffuses the printing light whose light quality has been adjusted.

The printing light diffused by the diffusion box 6 illuminates a negative film 10 set on the printing optical path 8.

This negative film 10 is held by a film holder 12 that moves in the Y-axis direction. This film holder 12
is attached to a slide stage 13 that moves in the X-axis direction. Furthermore, photosensors 14 and 15 are provided for detecting the initial positions (original positions) of the film holder 12 and the slide stage 13, respectively.

As shown in FIG. 2, the slide stage 13 is supported by a pair of guide rods 16 and 17, and is intermittently moved in the X-axis direction by an X-axis direction shift mechanism 18 at a predetermined pitch. A pair of guide rods 20 and 21 are installed on this slide stage 13, and the film holder 12 is movably supported on these. Furthermore, an opening 13a is provided at the center of this slide stage 13.

A film passage 22 for guiding the negative film 10 is formed in the film holder 12, and an opening 23 for passing printing light is provided in the center of the film passage 22. Furthermore, a lith film setting groove 26 is formed in the film boulder 13 at a position corresponding to the opening 23 for setting a lith film 25 with a boundary line 24 displayed thereon. This film holder 13 is intermittently fed in the Y-axis direction at a predetermined pitch by an X-axis direction shift mechanism 28.

The X-axis direction shift mechanism 1B and the X-axis direction shift mechanism 2
8 is a pulse motor, a feed screw rod rotated by this pulse motor, and a motor controller that controls the number of rotation stages and knobs of the pulse smoke according to the screen size and number of divisions! - Consists of rollers.

The film boulder is equipped with a grip part and positioning pins, and a plate placed separately from the film holder has a plurality of holes arranged in an I-Link shape, and the positioning pins are inserted into these holes. You can position the holder and perform divided printing.

A mask holder 32 is attached to the bracket 30 of the film boulder 12 via an attachment shaft 31 so as to be able to flip up. This mask boulder 32 has a box shape with an opening at the bottom, and an opening 32a is formed in the center of the mask boulder for allowing the burning light to pass through. Further, the mask holder 32 is provided with leg portions 32b at its tip, and the leg portions 32b come into pressure contact with the film boulder 13 when a solenoid (not shown) is activated.

The mask plate 33 has an exposure opening 33 approximately in the center thereof.
A is formed to flatten the negative film 10 and lithographic film 25 set in the film passage 22 and to regulate the screen size. Four pins 34 are implanted in this mask plate 33, the tips of which pass through the mask holder 32, and are secured with an E-ring or the like so that they do not come out. Further, in order to press the mask plate 33 downward, a spring 35 is fitted into each pin 34, respectively.

Boundary lines 24 are recorded on the lithographic film 25 to divide the original picture into seven trixes.

This lithographic film 25 can be easily created each time a document with a boundary line is photographed using a lithographic negative and then photographically developed. The width of the boundary line 24 is determined in accordance with the gap between each divided printed photograph when the obtained divided printed photographs are displayed as a photo display. In other words, if you want to line up each divided print photo without any gaps, make the border line so thin that it disappears when cutting along this border line, and if you want to line up the divided print photos with a predetermined gap between them, use this border line. Cut along the inner edge of this border to create a thick border that corresponds to the gap. Note that the boundary display lithium film 25 of this embodiment is used when one screen is divided into 4 rows and 4 columns for printing.
When performing split printing such as 3 rows and 3 columns, 5 rows and 5 columns, etc.
Those with border lines that match these are used.

As shown in FIG. 1, a scanner 35 is disposed obliquely above the mask plate 33, and measures the light of the entire screen through the opening 33a of the mask plate 33. This scanner 35 is composed of a lens 36 and an image area sensor 37, and sends the photometric values read at each point to a characteristic value calculation section 38. This characteristic value calculation section 3
8 calculates characteristic values for each color, such as average transmission density, maximum density, minimum density, average density of a specific area, etc. of the entire screen from the photometric values of each point, and sends these characteristic values to the controller 40.

Above the film boulder 13 is a zoom lens 41.
The zoom lens 41 is driven by a pulse motor 42 via a gear or the like. Further, between the zoom lens 41 and the photographic paper 43, there are arranged a shutter 46 controlled by a shutter drive section 45 and an easel mask 48 having an opening 47 corresponding to the print size.

The photographic paper 43 is pulled out one frame at a time from the photographic paper roll 51 by the rotation of the transport roller pair 52 and set at the exposure position. A cutter 53 is arranged next to the mask 48, and when a certain number of frames are enlarged and printed,
Cut the exposed portion into long pieces.

As is well known, the photographic developing section 55 includes a developing tank, a fixing tank, a rinsing tank, and a drying drum, and performs photographic processing by sequentially passing through these processing tanks, and finally performs drying processing.

The direction and amount of rotation of each pulse smoke that drives each of the shift mechanisms 18.2B, the conveyance roller pair 52, and the zoom lens 41 is controlled by the controller 40. This controller 40 is composed of a microcomputer, and is a memo! The filter adjustment section 7 and shutter drive section 45 are also controlled according to the programs stored in J60.

The keyboard 61 includes a format/selection key 62 for selecting a desired one from predetermined section formats, a print key 63 for instructing to start printing, a power key 64, and a button for manually moving the film carrier. A movement key 65 is provided for moving the camera.

Next, the operation of this embodiment will be explained.

After turning on the power key 64, flip up the mask plate 33, set the negative film 10 in the groove 22 of the film holder 13, and align the screen to be divided and enlarged with the opening 23. Then, the border display lithographic film 25 is placed on the negative film 10 and set in the setting groove 26 of the film holder 12. After that, a mask plate 33 is placed on the film, thereby pressing and fixing the negative film 10 and the lithographic film 25. Next, the format i selection key 62 is operated in accordance with the section format of the border display lithographic film 25 that has been placed. Thereby, the controller 40 selects a predetermined rotation sequence from among a plurality of rotation sequences stored in the memory 60 according to the section format of the set lithographic film 25, and also selects an enlargement ratio.

When the print start key 64 is turned on, the controller 40 changes the focal length of the zoom lens 55 via the driver 42a1 and the pulse motor 42 in accordance with the magnification read out from the memory 60. Additionally, the controller 40 operates each shift mechanism 18.28 to move the film holder 12.
Set to the initial position 'fl. Completion of setting to the initial position is detected by photosensors 14 and 15.

Next, the controller 40 reads Ife'' from the memory 60.
1, each shift mechanism 18.
28 is driven to align the center of the screen of the negative film 10 with the printing optical path 8. This position becomes the standard position and is the "0" position in FIG.

Next, the controller 40 uses the scanner 35 to measure red, green, and blue transmitted light for the entire screen of the negative film 10 positioned at the standard position. Each photometric value is
The average transmitted density 1. The maximum density, minimum density, average density in a specific area, etc. are calculated and sent to the controller 40. The controller 40 calculates the exposure amount for each color from the characteristic value, and adjusts the insertion amount of the color filters 3 to 5 into the optical path according to each obtained exposure amount.

After calculating the exposure amount, the controller 40 drives each shift mechanism 18, 28 to move the film holder 12 and slide stage 20 according to the rotation sequence. First, as shown in FIG. 4, when the first area "1" in the first row and first column is set at the print position and the shutter 46 is opened for a predetermined period of time, the image in area "1" is printed on the photographic paper 4. It is burned into.

After this exposure, the conveying roller pair 52 rotates by a certain amount to convey the photographic paper 43 by one frame and set the unexposed portion to the exposure position. Thereafter, the X-axis direction shift mechanism 18 is driven to move the slide stage 13 by a predetermined pitch. As a result, area "2" is set at the print position,
The image of area "2" is printed onto photographic paper 43. Thereafter, each shift mechanism 18, 28 and pair of transport rollers 52 are driven to set each area at a print position in the order shown in FIG. 4, and then images in each area are sequentially printed on photographic paper 43. In this way, when the enlarged printing of the entire screen area is completed, the negative film 10 is returned to the initial position.

The exposed photographic paper 43 is stocked in a loop in the photographic developing section 55, and when a predetermined number of frames have been printed, a cutter 53 is operated to cut it into long pieces. The cut long photographic paper 43 is sequentially immersed in each processing tank of the photographic developing section 55 to be developed. The developed photographic paper 43 is cut into frames, for example, 1-ray 5.
It is discharged at 6.

As shown in FIG. 5, the photographic paper 43 discharged to the tray 56 is cut manually, for example, along cutting lines 58 on which the boundaries 24 of each area are printed, and the portions indicated by diagonal lines in the figure are cut. is cut off and split print photo 5
7 is obtained.

FIG. 6 shows an example of a photographic display 70 using the divided printed photograph 57 of the present invention.

The photo display 70 is constructed by arranging divided print photos 57 at positions corresponding to the original image without gaps and pasting them on a mount 72 such as paper. The divided print photographs 57 arranged in this manner are viewed as one enlarged print photograph as a whole.

In addition, when each divided print photograph 57 is arranged on the mount 72 or the like with a gap between them, the border line 24 of the boundary line display lith film 25 is formed to have a thickness corresponding to this gap. Then, after the development process, by cutting along the inner edge of the cutting line on which the boundary line is printed, a mosaic-like photographic display without positional deviation can be formed.

In each of the above embodiments, the film J and holder 12 are automatically moved by each shift mechanism 18.2El to print each area, but each time the moving gear 83 is operated, the film holder 12 can be moved freely. You can also move it around and print each area manually. In this case, the film holder 12 can be positioned while checking the boundary line 24 of the boundary display lithographic film 25.

Further, the present invention provides a lever to be attached to the film boulder and a movement position regulating means for positioning the film boulder when each area matches the print position, so that the film boulder and the slide stage can be manually moved. It is also possible to move and print each area.

[Effects of the Invention] As explained above, according to the present invention, a lithographic film with a boundary line recorded thereon is superimposed on a photographic film to be divided and printed, and the printing position is set along the cutting line where this boundary line is printed. Since unnecessary parts around the edges are cut off, even if there is a slight deviation in the movement of the film boulder, it is possible to obtain divided print photographs of images that accurately correspond to the images in each area, regardless of this deviation. . This split pudding!・Place the photo in the position corresponding to the original picture 4
By doing this, it is possible to create, for example, a photo display in which printed photos are lined up without gaps. In addition, by making the thickness of the border line correspond to the gap between each divided print photo on the photo display, even if the divided print photos are separated by a predetermined gap on the photo display, the images of the divided print photos can be easily displayed. , it is possible to accurately correspond to the image of each area regardless of the feeding accuracy of the film boulder.

In addition, since you can actually check the boundaries of each area before split printing, you can move the border lines so that important parts of the image do not span multiple split print photos. becomes possible. Therefore, it is possible to avoid creating divided print photographs in an unnatural divided state.
