BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photoprinting method and a photoprinting apparatus, and more particularly, to a photoprinting method and a photoprinting apparatus capable of forming a panoramic size printed image without increasing the size of a paper mask.

0002

2. Description of the Related Art In order to print a plurality of image sizes in a photo printing machine, paper masks of sizes corresponding to the image sizes are prepared. When printing a normal size image in a photo printing machine, printing is performed using a paper mask for normal size printing. If you want to print a panoramic image that is longer in the horizontal direction of the screen than a normal size image, use a paper mask that is longer in the horizontal direction than the normal size paper mask and print it in one time. A panoramic-sized printed image is formed.

0003

However, in the printing method using the photoprinting machine described above, it is necessary to prepare a paper mask for printing a panoramic size image separately from a paper mask for printing a normal size image. Moreover, since the horizontal length is longer than a normal size paper mask, it is necessary to take up more space for the mask.
The equipment becomes larger.

SUMMARY OF THE INVENTION In view of the above facts, the present invention aims to provide a photographic printing method and a photographic printing apparatus that can form a panoramic size printed image without increasing the size of the paper mask.

[0005]

[Means for Solving the Problems] The photographic printing method according to the invention of claim 1, when creating a horizontally long print having a longer length in the horizontal direction of the screen than a standard size print, prints a frame image of a film in the horizontal direction of the screen. The method is characterized in that it is divided into a plurality of image areas adjacent to each other in the direction, and after exposing the image of these image areas, the paper is moved to create a horizontally long print.

A photo printing device that prints frame images onto paper, in which the transmittance near the edge corresponding to the boundary of each image area gradually decreases from the edge corresponding to the vertical edge of the frame toward the boundary side edge. After exposing the image of the predetermined image area by arranging one filter so that the edge of the formed pair of filters corresponds to the border of the predetermined image area, the paper is moved and the border is removed. exposure control means for exposing the image of the image area adjacent to the predetermined image area by arranging the other filter so that the side edge corresponds to the boundary of the image area adjacent to the predetermined image area; have.

The photographic printing apparatus according to the third aspect of the invention is characterized in that a mask of a size for printing frame images of a standard size is further provided.

[0008]

[Operation] In the photographic printing method according to the invention of claim 1, a frame image on a film is divided into a plurality of image areas adjacent to each other in the horizontal direction of the screen, and after the image areas are exposed, the paper is moved to create a horizontally long print. . According to the first aspect of the invention, since a horizontally long print is created by dividing the image into a plurality of image areas and moving the paper and exposing it to light, a horizontally long print can be created without increasing the size of the paper mask.

For example, if the horizontal length of a landscape-sized print is twice the standard size and the vertical length is the same, the landscape-sized print is divided into two equal parts and created in two batches. By doing so, a horizontal size print can be created using a standard size paper mask.

In the photographic printing apparatus according to the invention of claim 2,
A frame image with a small screen ratio compared to a frame image of the standard size is divided into multiple image areas that partially overlap at the border, and the transmittance near the edge corresponding to the boundary of the image area corresponds to the vertical edge of the frame. All the frame images are printed on the paper by multiple printings through a pair of filters that are formed to gradually become smaller from the edge toward the boundary side edge. That is, one of the filters is arranged by the exposure control means so that the boundary side edge corresponds to the boundary of the predetermined image area, and the image of the predetermined image area is exposed.

After exposure, the paper is moved by the exposure control means, and the other filter is arranged so that the border side edge corresponds to the border of the image area adjacent to the predetermined image area, and the paper is placed in the predetermined image area. Expose images of adjacent image areas. By performing this operation over all remaining image areas, all frame images are printed onto paper.

As described above, in the photographic printing apparatus of the second aspect, exposure is performed twice with the filter arranged so that the border side edge of the filter corresponds to the border of the image area. In this case, the transmittance near the edge corresponding to the boundary of the image area gradually decreases from the edge corresponding to the vertical edge of the frame toward the edge on the boundary side. Therefore, since the transmittance of the filter in the two exposures can be considered to be substantially the same over the entire area of the filter, it is possible to create a good horizontally long print without blurring in the center. Further, since a frame image on a film is divided into a plurality of image areas and the paper is moved and exposed to create a horizontally long print, it is possible to create a horizontally long print without increasing the size of the apparatus.

The photographic printing apparatus according to the third aspect of the invention further includes a mask having a size for printing frame images of a reference size. Therefore, in addition to horizontal size prints, standard size prints can also be created using the same device.

The dimensions are set slightly larger than half.

The operation of this embodiment will be explained below. In this embodiment, after forming the right burned image 75, the left burned image 74 is
One panoramic size printed image 78 is formed by printing twice.

When forming the panoramic size printed image 78, first, the exposure amount is calculated. That is, as shown in FIG. 8, the negative film 32 is moved by the motor 42 so that the right negative image 88 is placed on the printing optical path L. In this state, the amount of light emitted from the light source 16 and transmitted through the right negative image 88 is detected by the light receiver 64, and a signal based on this amount of transmitted light is supplied to the control section 66. Next, the operation of the motor 42 is controlled by the control section 66, and the negative film 32 is moved by the conveying roller 38 so that the left negative image 86 is placed on the printing optical path L as shown in FIG. In this state, the amount of light emitted from the light source 16 and transmitted through the left negative image 86 is detected by the light receiver 64,
A signal based on the amount of transmitted light is supplied to the control section 66. The control unit 66 controls the left negative image 86 and the right negative image 88.
The LATD (accumulated transmitted density) of the panoramic negative image 72 is determined from the amount of transmitted light at
The exposure amount is calculated based on TD. In this state, a right printed image 75 is formed, and a left printed image 74 is formed by moving the negative film 32 and photographic paper 16.

When forming the right printing image 75, the operation of the drive unit 80 is controlled by the control unit 66, and the panoramic mask 30 is placed on the negative image so that the right image printing filter 82 is positioned on the left negative image 86. The film 32 is moved in a direction perpendicular to its longitudinal direction. Further, the operation of the motor 24 is controlled by the control unit 66, and the photographic paper 16 is conveyed by an amount corresponding to 1/2 frame of printing, and the paper mask 1
4 (Figure 7).

In this state, the light emitted from the light source 16 and transmitted through the left negative image 86 and the right image printing filter 82 causes the transmitted image to be printed on the photographic paper 16 at the predetermined exposure amount calculated above. In this case, as mentioned above,
Since the right image burning filter 82 has the density distribution shown by the solid line A in FIG. 6B, the transmittance of the right image burning filter 82 has the distribution shown by the solid lines D1, D2 and the broken line D3 in FIG. 6C. Ru. Note that the vertical axis in FIG. 6C represents the filters (right image burning filter 82 and right image burning filter 84).
The horizontal axis shows the transmittance from the light shielding part 37A to the light shielding part when the right image burning filter 84 and the right image burning filter 82 are arranged so that the transmitted light amount adjusting part 44A and the transmitted light amount adjusting part 44B overlap with each other. This is the distance to 37B.

Next, a left printed image 74 is formed. In this case, the operation of the drive section 80 is controlled by the control section 66, and the panoramic mask 30 is moved so that the left image printing filter 84 reaches the conveyance path of the negative film 32. In this case, the position where the image printed by the light transmitted through the transmitted light amount adjusting section 44A and the printed image created by the light transmitted through the transmitted light amount adjusting section 44B overlap, that is, the boundary portion 76 and the neighboring areas 74B, 74B are printed twice. The panoramic mask 30 is moved as follows. Also, the control unit 66 controls the motor 4.
2 is controlled, and the negative film 32 is moved by the conveying roller 38 so that the right negative image 88 is positioned on the left image printing filter 84. In this embodiment, this moving distance is set to 7.44 mm. Further, the operation of the motor 24 is controlled by the control unit 66, and the photographic paper 16 is moved by 1/2 frame in the direction opposite to the negative film 32 (to the right in FIG. 1) and positioned on the paper mask 14 (see FIG. 8). In this embodiment, the moving distance of the photographic paper 16 is set to 131 mm. therefore,
The horizontal length of this boundary portion 76 and the neighboring regions 75B and 74B is 4 mm. In this state, light is emitted from the light source 16 toward the left negative image 86. In this case, the transmitted image is printed onto the photographic paper 16 by the light that has passed through the left negative image 86 and passed through the left image printing filter 84 . As described above, since the left image burning filter 84 has the density distribution shown by the solid line B in FIG. 6B, the transmittance of the left image burning filter 84 is as shown by the solid lines D4, D5 and the broken line D6 in FIG. 6C. be made into

In the above two baking operations, the solid line D1 in FIG. 6C
, D2, D4, and D5 (the right image printing filter 84 and the right image printing filter 82), the image is printed on the photographic paper 16. In other words, a filter (right image printing filter 84 and the right image burning filter 82), it is possible to uniformly print the entire panorama-sized print image 78 without blurring, as well as the border 76 and the neighboring areas 75B and 74B.

A negative image 73 (FIG. 5) formed on the negative film 32 and arranged next to the negative printed image 72 (FIG. 5)
), use the negative film 32 as shown in Fig. 5 (Fig. 1).
Transport it to the right and repeat the above operation.

In the above example, the panoramic size printed image 78
It is necessary to move the negative film 32 in both the left and right directions in FIG. 7 (FIG. 8) each time one film is formed, but since the exposure amount is calculated as described above during this movement process, the moving operation can be used effectively. .

As described above, in this embodiment, the panoramic size negative printed image 72 is divided into a plurality of image areas, and printing is performed for each image area by moving the photographic paper 16, so that the size of the paper mask 14 is A panoramic-sized printed image 78 can be formed without increasing the size.

Furthermore, in the above embodiment, the panoramic size printed image is 254 mm x 89 mm, that is, the length in the width direction is the same as the normal size (89 mm x 127 mm), and the length in the longitudinal direction is twice as long. Since the printed image is divided into halves and printed twice using the printer, it can also be used as a paper mask for printing a normal size negative image, and it is possible to prevent the paper mask from becoming large and the photo printing device from becoming large. Therefore, when switching between normal size and panoramic size printing, it is only necessary to replace the printing lens and negative mask. Therefore, even if panoramic size printing and normal size printing are performed alternately, the printing can be performed using a conventional photographic printing apparatus with a simple configuration.

Another embodiment of the panoramic mask 30 is shown in FIG. In this embodiment, a light transmission hole for forming a normal size printed image is provided on the lower side of the left image printing filter 84 in FIG. 9 (in the direction perpendicular to the longitudinal direction of the negative film when the negative film is placed). 90 is formed. When using the panoramic mask 30 of this embodiment, a transmission hole 90 is provided in the photographic printing apparatus 10 by the motor 42 such that it can be placed in a passage through which a normal-sized negative printed image passes. In this embodiment, it is possible to form a panoramic size and a normal size printed image simply by controlling the amount of movement of the panoramic mask 30 using the motor 42.

In the above embodiment, the left image burning filter 8
4. Although the right image printing filter 82 is arranged in a direction perpendicular to the longitudinal direction of the negative film, it may be arranged along the longitudinal direction of the negative film 32. In this case, the panoramic mask 30 is provided so as to be movable in the longitudinal direction of the negative film, and the motor 42 moves the panoramic mask 30 in the longitudinal direction of the negative film 32 so that the left image printing filter 84 and the right image printing filter 82 are moved to the negative film. The printing is performed by switching to the 32 conveyance paths alternately.

Furthermore, in the above embodiment, the left image burning filter 84 and the right image burning filter 82 are formed so that the amount of light irradiated to the boundary portion 76 is the same as that of other portions. It may be formed by taking into account the unevenness of the amount of light that sometimes occurs on a panoramic size printing screen due to the optical system of the camera.

[0040] Furthermore, in the panoramic mask 30,
The edges of the mask frame 31 may be substituted for the light shielding parts 37A and 37B.

Although a panoramic size print has been described as an example of a horizontally long print, a high-definition size print having the same screen ratio as a high-definition image may also be created.

[0042] In the above example, the size of the printed image is 89 mm x
254 mm is described as an example, but the present invention is applicable to general horizontal prints that are longer in the horizontal direction of the screen than standard size prints.

[0043]

As configured as described above, according to the present invention, it is possible to obtain a photographic printing method and a photographic printing apparatus that can form a panoramic size printed image without enlarging the paper mask. effective.
