Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a photographic display and a printer, and more specifically, it divides an original picture into matrix-like areas and prints each area enlarged to produce a divided print photograph. The present invention relates to a photographic display and printer attached to a supporting member such as a mount in accordance with the position on the original image.

[Conventional technology]

Traditional photographs are recorded on photographic film using various printers such as photo printing machines and video printers.
It is created by enlarging and printing a screen (one frame) or one screen displayed on a CRT onto photographic paper.

In this way, when printing one frame of photographic film or the like on large-sized photographic paper, a large printing area is required. Therefore, the device becomes large, the cost of the device itself increases, and large-sized photographic paper is required.
Printing costs will also be high. Therefore, by dividing the original picture into a matrix, enlarging each divided area to create divided print photographs, and arranging them according to their positions on the original picture, essentially one enlarged photograph can be created. Formed so-called photographic displays are also provided.

[Problem to be solved by the invention]

In the photographic display as described above, gaps are provided between the divided printed photographs when the divided printed photographs are arranged in correspondence with the positions on the original image. This is because the ability to read visual information, that is, the ability to fill in missing parts of an image, makes it possible to correct misalignment of print frames of each divided print photo caused by uneven feeding of the photosensitive material. However, this visual information reading ability is only effective when observing from a sufficient distance; when observing from a close distance, the existence of this gap becomes larger, giving the viewer a sense of discomfort. There is a problem with this.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to create a photographic display with a simple structure that gives a rich impression even when observed up close.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides divided print photographs with division frames having a width corresponding to the gaps between each divided print photograph when attached to a supporting member such as a mount, and divides the divided print photographs into a matrix. It is designed to be subdivided into small section pieces. Further, it is preferable that the division frame is recorded during printing exposure of the divided print photograph. Further, a printer that prints and exposes divided print photographs may be configured to record a partition frame having a width corresponding to the gap between each divided print photograph when attached to a support member, when printing and exposing the divided print photographs. preferable.

[Effect]

At the time of printing exposure of the divided print photographs, a partition frame having a width corresponding to the gap between each divided print photograph when attached to the support member is recorded. The divisional print photograph is subdivided into matrix-like small divisional pieces by this division frame. As a result, it is possible to easily create a photographic display that can give a rich impression even when viewed up close.

This division frame 3 is composed of vertical division lines 3A and horizontal division lines 3B arranged at a predetermined pitch, and is used to subdivide each of the divided print photos FIL to FIOIO into small division pieces 4 in a matrix. be. The width of the division frame 3 is the width of each divided print photo Fil to FIOIO when the divided print photos Fil to FIOIO are attached to the mount 1.
The width is approximately the same as the width of the gap formed between the two.

The image signal of a negative image of a negative film or a positive image of a printed photograph, etc., inputted by the image input section 20 is converted from an analog signal to a digital signal by an A/D converter 21, as shown in FIG. , are stored in the entire image storage section 22.

A necessary area of the image signal stored in the entire image storage section 22 is read out by an area selection circuit 23. For example, as shown in FIG. 3, the area corresponding to the divided print photo File in the 1st row, 1st column in the upper left is read out sequentially moving to the cloth, and the divided print photo in the 1st row, 10th column in the upper right After reading out the area corresponding to the print photo F110, it moves to the next area corresponding to the divided print photo F21 in the second row and first column, and then to the area corresponding to the next divided print photo F21 in the second row, and then to each of the divided print photos in the 3rd to 10th rows. Read out the areas in sequence. Furthermore, instead of sequentially reading out areas in the row direction, areas may be read out sequentially in the column direction. These square readings of each area are performed for each color and stored in the frame memory 24 provided for each color.

First, the image input section 20 inputs an original image recorded on a negative film or the like, and stores this image signal in the entire image storage section 22 via the A/D converter 21.

The area selection circuit 23 selects the area according to the burning order of each area.
The central coordinate position of the area to be printed is designated, the image signal of each pixel included in a fixed rectangular area centered on this is read out, and this image signal is written into a frame memory 24 provided for each color. As shown in FIG.
When installing, each divided print photo FIL-FIO
In order to form a gap S between the connecting side edges of the IO, each area is made shorter by the width of the gap S than each area in which the original image is divided into a matrix.

Further, among the image data written in the frame memory 24, the image data at the address of the division frame 3 is stored in the division frame writing circuit so that the division frame 3 portion after printing has the same color as the background color of the mount 1. 24A. For example, when the background color of the mount l is white, the image data at the address corresponding to the partition frame 3 in the frame memory 24 is rewritten to "0".

The image data stored in the frame memory 24 is read out by the image processing unit 25, and in addition to saturation correction and gradation correction, color balance and density correction are performed as necessary in the image processing unit 25. CR based on this corrected image signal
The CRTIO for exposure is driven via the T drive section 27.

As a result, for example, each monochromatic image of a rectangular region in the area of the first row and first column is sequentially displayed on the CRTIO for exposure, and sequential exposure of three color planes is performed. Therefore, as shown in FIG. 2, the divided print photograph Fil in the first row and first column, which is divided into matrix-like subdivision frames 4 by the division frame 3, is recorded on the color paper 16.

Next, the area selection circuit 23 specifies the center coordinates of the area corresponding to the divided print photo F12 in the first row and second column, and as described above, the three-color image signals of the rectangular area corresponding to the area are converted into the entire image. The data is read from the storage unit 22 and written to the frame memory 24. Further, the image data of the partition frame 3 is rewritten by the partition frame writing circuit 24A. The exposure CRTIO is driven based on the image data in the frame memory 24A. Thereafter, a third exposure for exposing the next divided print photograph F13 is performed in the same manner. In this way, the divided print photos F1 will be sequentially divided.
4-Expose and create FIOIO. The created divided print photographs F1010 are pasted on a mount l at positions corresponding to the original picture, as shown in FIG. 3, to form a photographic display 2 in which the original picture is enlarged.

In addition, in the above embodiment, the divided print photo File ~
Although the FIOIO has been shown to be affixed to the mount 1, a support member (not shown) having transparent pockets into which segmented printed photographs are inserted may alternatively be used to form a photographic display.

Furthermore, a photo display is formed by creating rows or columns of split print photos in which the split print photos are grouped into rows or columns and arranged sequentially at predetermined intervals, and these are placed on a support member. Good too.

In addition, in the above embodiment, the divided print photo File ~
Although the printing exposure of FIOIO was performed using a CRT for exposure, the present invention is not limited to this. , during this printing exposure, the partition frame 3
A division frame inserting plate (not shown) having recorded thereon may be inserted into the printing optical path so that the division frame 3 may also be printed and exposed at the same time.

〔Effect of the invention〕

As explained above, according to the present invention, since the divided print photograph is provided with a division frame having a width corresponding to the gap between each divided print photograph when attached to the support member, the division frame allows the divided print photograph to be separated. It is subdivided into matrix-like small section pieces, which prevents the gaps between each divided print photo that are formed when each divided print photo is attached to the support mount from becoming noticeable due to the presence of similar section frames. You can avoid it. Therefore, it is possible to create a photographic display that can give the impression of a mosaic panel photograph rich in taste even when viewed up close. Moreover, since each division frame is exposed to printing simultaneously with the printing exposure of the divided print photograph, it is possible to easily create a divided print photograph in which the division frames are formed.
