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

[0002]

2. Description of the Related Art In a photoprinting machine, a paper mask having a size corresponding to an image size is prepared in order to print a plurality of image sizes. When printing a normal size image in a photo printing machine, printing is performed using a paper mask for normal size printing. When printing a panorama-size image that is longer than the normal-size image in the horizontal direction of the screen, use a paper mask that is longer in the horizontal direction than the normal-size paper mask in one printing. A printed image of a panoramic size is formed.

[0003]

However, in the printing method using the photographic printing machine, it is necessary to separately prepare a paper mask for printing a panoramic size image in a normal size. Moreover, since the length in the horizontal direction is longer than that of a normal-size paper mask, it is necessary to increase the space occupied by the mask.
The device becomes larger.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a photographic printing method and apparatus capable of forming a panoramic-size printed image without increasing the size of a paper mask.

[0005]

According to a first aspect of the present invention, there is provided a photographic printing method for printing one frame of a film image on a screen when creating a horizontally long print having a longer screen width than a reference size print. Multiple images that are adjacent horizontally
The image is divided into image areas in which the relative orientation of each image area is constant, and the paper is moved each time all the images in each image area are exposed with a constant printing light amount to create a landscape print.

According to a second aspect of the present invention, there is provided a photographic printing apparatus in which a frame image having a small screen ratio with respect to a frame image of a reference size is divided into a plurality of image areas partially overlapping at a boundary portion, and the entire image is printed a plurality of times.

Exposure control means for arranging the other filter so that the side edge and the boundary of the image area adjacent to the predetermined image area correspond to each other, and exposing an image in the image area adjacent to the predetermined image area. , The has.

A photographic printing apparatus according to a third aspect of the present invention is characterized in that a mask having a size for printing a reference size frame image is further provided.

[0008]

In the photographic printing method according to the first aspect of the present invention, one frame of a film image (frame image of a film) is divided into image regions in which the relative orientation of a plurality of images adjacent in the horizontal direction of the screen is constant . Burn all the images in each image area
Each time the exposure is performed with the applied light amount, the paper is moved to create a landscape print. According to the first aspect of the present invention, a landscape print is created by dividing the image into a plurality of image areas and exposing the paper while moving it, so that a landscape print can be created without increasing the size of the paper mask.

For example, if the width of a horizontally long print is twice as large as the reference size and the length in the vertical direction is the same, the horizontally long print is divided into two equal parts and created twice. By doing so, a horizontally long print can be created using the paper mask for the reference size.

[0010] In the photographic printing apparatus according to the second aspect of the present invention,
A frame image whose screen ratio is smaller than that of the standard size frame image is divided into multiple image areas that partially overlap at the border, and the transmittance near the edge corresponding to the border of the image area corresponds to the vertical edge of the frame The entire frame image is printed on the paper by printing a plurality of times through a pair of filters that are gradually reduced from the edge to the boundary portion side edge. That is, the exposure control means arranges one of the filters so that the boundary side edge corresponds to the boundary of the predetermined image area, and exposes the image in the predetermined image area.

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

As described above, in the photographic printing apparatus according to the second aspect, the filter is used twice in a state where the filter is arranged so that the boundary side edge of the filter and the boundary of the image area correspond to each other. Is formed such that the transmittance in the vicinity of 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 boundary-side edge. 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, a good landscape print without blurring in the center can be created. Further, since the frame image of the film is divided into a plurality of image areas, and the paper is moved and exposed to create a landscape print, a landscape print can be created without increasing the size of the apparatus.

The photographic printing apparatus according to the third aspect of the present invention is further provided with a mask of a size for printing a reference size frame image. Therefore, in addition to a horizontally long print, a print of a reference size can be created by the same apparatus.
