The present invention relates to a film unit with a lens loaded with an APS film and a film unit system with a lens for obtaining a printed photograph from the loaded APS film.

[0002]

2. Description of the Related Art A film unit with a lens is a simple camera which does not require loading and unloading of a film before and after photographing by supplying a film in advance. This lens-equipped film unit is also commercially available with an APS film loaded therein.

[0003] APS (Advanced Photo)
System) film is a film whose print size can be switched, and various sizes such as a large size (high definition) corresponding to one exposure frame, a small size smaller than the exposure frame (classic), or a horizontally long panorama size are selected. By doing so, an arbitrary print photograph can be obtained. Even in such an APS film,
There is provided one having a pre-exposure unit in which a latent image such as a landscape or a character is previously exposed. When a print photograph is obtained from the film on which the latent image is imprinted, the actual photographed image and the image of the pre-exposure unit are included in one frame, so that the print photograph can be interesting.

[0004]

SUMMARY OF THE INVENTION However, APS
Since the print size of the film can be selected, if the latent image is projected in the same range as a general film, the latent image may be partially lost or only one copy may be printed. is there. For example, if the latent image is provided outside the panoramic size and printed in small size, the latent image will be missing on the left and right, and if the latent image is provided outside the small size and printed in panoramic size, the latent image will be printed. Images may be chipped up and down. As a result, there is a problem that an unnatural or incomplete print photograph is obtained.

Further, in an APS film on which a latent image is imprinted, the density may differ between an actually photographed image and an image of the latent image depending on photographing conditions. Since the density at the time is determined by the sum of the photographed image and the image of the latent image, the density of the photographed image is different from the actual photographing, and there is also a problem that the print becomes unnatural.

The present invention has been made in consideration of such a conventional problem, and has been developed in consideration of an AP having a latent image imprinted thereon.
It is an object of the present invention to provide a lens-equipped film unit that can normally print a latent image even on an S film.

Further, the present invention provides a film unit system with a lens capable of producing a printed photograph in which the density of a photographed image does not fluctuate due to a density difference between an actual photographed image and a latent image. The purpose is to:

Optically recorded. Therefore, the slide plate 35 also functions as size selection means.

Next, the structure of the APS film 20 will be described.

The APS film 20 is, as shown in FIG.
A plurality of exposure frames 21 for photographing one frame at a time are formed at regular intervals along the length direction. Further, rectangular hole-shaped perforations 24 for applying a hoisting force are formed side by side at positions corresponding to the end portions of the respective pieces.

Each exposed frame 21 has an unexposed portion 22
And a pre-exposure unit 23. Pre-exposure unit 23
Is a portion where a latent image such as a landscape or a character has been exposed in advance, and the subject is photographed with respect to the unexposed portion 22. The pre-exposure unit 23 is provided at a desired position of the print size selected by the size selection unit 35, as described later.

In order to prevent re-exposure to the pre-exposure section 23 during photographing, the exposure frame 12 is provided with a light-shielding frame 25 as shown in FIG. The light-shielding frame 25 is located on the front side of the film 20, and blocks light to the pre-exposure unit 23 by covering the front surface of the pre-exposure unit 23.
In order to perform this blocking, the light-shielding frame 25 extends to the boundary between the pre-exposed portion 23 and the unexposed portion 22.

Further, on the opposite side of the APS film 20 from the perforations 24, a track-shaped recording section 27 is provided corresponding to each exposure frame 21. When a pre-exposure unit 23 is provided for each exposure piece 21, the recording unit 27 magnetically records the presence or absence of the pre-exposure unit 23 and the arrangement position of the pre-exposure unit 23 at the stage of manufacturing a film unit with a lens. . In addition, print size selection information is also recorded. In addition, the optical marks M ₁ ,
The selection information of the print size can be recorded by using M _2. That, P (panorama) only M ₁ or M ₂ is recorded in size, are recorded both in the C (classic) Size, H (high definition) not both recorded in size. A photograph is printed based on the information recorded in the recording section 27 and M ₁ and M ₂ .

Next, the setting of the print size on the APS film 20 will be described with reference to FIGS. In each figure, a frame 21 indicates an exposure frame.

The C (classic) size has a width (x) of 22.3 as indicated by hatching in the lower left of the figure.
(+1.49, -0.85) mm and vertical width (y) is 15.
6 (+0.25, -0.42), and the P (panorama) size is x = 27.4 (± 0.39) and y = 9, as indicated by hatching in the lower right of FIG. 6 (+
1.93, -0.34), and the H (high definition) size covers the entire range of FIG.
27.4 (+0.39, -1.11), y = 15.6
(+0.25, -0.42). Therefore, here, C is a small size, H is a large size, and P is a horizontally long size.

Next, the range of forming a latent image (pre-exposed portion) in the present invention will be described with reference to FIGS.

FIG. 8 shows an example in which a latent image is formed in a range S1 (upper and lower ends of an exposure frame) other than the P (panorama) size.

If a latent image is formed in this range, when printed, the latent image is printed at H size and C size, but not printed at P size. Also, if the main part of the character is within the range of a, it is printed in each size of H and C, but not all in the P size. Here, the main part of the character means a part such as a person's face or an animal's face that can be naturally recognized by the character without a sense of incongruity if there is such a part.

FIG. 9 shows an example in which a latent image is formed outside the C size range (left and right end regions) S2. If a latent image is formed in this range, only the C size latent image will not be printed,
Other sizes will be printed. If the main part of the character is in the range of b, printing is performed in each of the sizes H and P, but not all in the C size.

FIG. 10 shows a case where a latent image is formed in a range S3 extending slightly above the boundary of the P size from the lower side of the exposure frame 21.

In this case, the latent image appears in prints of all sizes, but in the C size, both sides are slightly missing, and in the P size, the lower half is missing. That is, if there is a character in the range of a and c in the figure, the character is printed in all sizes.

FIG. 11 shows an example in which a latent image is formed in a range S4 located slightly below the upper boundary of the P size from the upper side of the exposure frame 21.

In this case as well, the latent image appears on the prints of all sizes.
With the P size, a print in which the upper half is missing is obtained.

That is, if there is a character in the range of a and d in the figure, the character is printed in all sizes.

FIG. 12 shows an example in which a latent image is formed in a range S5 extending the same distance from the left edge of the exposure frame 21 to the inside of the C-size frame.

According to this state, a latent image is printed in all sizes of C, H, and P, but the right half is missing in the C size, and the upper and lower ends are missing in the P size. That is, if there is a character in the range of b and e in the figure, the character is printed in all sizes.

In addition to the above-described embodiments, latent images can be formed in various ranges using the same reference as described above.

It should be noted that the forms shown in each of the above figures show the imprinting on a film (negative), and it goes without saying that the print position is upside down and left and right.

Next, an example of the display means of the present invention will be described.

FIG. 6 shows a slide plate 35 as an example of the display means.
The shape of each of H and 35C is adjusted to the shape of the unexposed portion (the range actually used for photographing) so as to exclude the latent image forming range shown in FIGS. It will be configured to be visible. That is, when a film on which a latent image is formed by any of the above-described FIGS. 8 to 12 or a combination thereof is incorporated into a unit, a slide plate having a window corresponding to the latent image must be incorporated at the same time. good.

In this way, when the user takes a picture, the user can see the display (window) of the finder to know the range in which the picture can be taken, so that a picture with a reliable latent image can be obtained.

The display means is not limited to the one which slides in the horizontal direction as described above, but may be a rotary plate type which rotates by pressing a button.

Next, a system for printing a negative film of an APS film as a photograph will be described. In this system, information magnetically recorded in the recording unit 27 is read before printing. The presence or absence of the pre-exposure unit 23 and the arrangement position of the pre-exposure unit 23 are magnetically recorded in the recording unit 27, and the position of the pre-exposure unit 23 is determined by reading this information.

Thus, during the printing process, only the density of the image photographed in the unexposed section 22 is measured while avoiding the image of the pre-exposed section 23. Then, the print density is determined based on the measured value. By performing such print processing, the print density of the photographed image is determined at an appropriate value without being affected by the image of the latent image, so that the photographed image can be printed at an appropriate value. Thus, the photographed image can be printed with a natural feeling.

This system can be applied to a digital printer. That is, the entire negative film is scanned, and different print densities are determined for the latent image and the photographed image based on information on the presence or absence of the pre-exposure unit 23 and the arrangement position of the pre-exposure unit from digital data obtained by the scan. can do. In this case, not only the density of the photographed image in the unexposed portion can be determined by calculation from digital data obtained by scanning the APS film, but also the density of the latent image portion can be determined. A photographed image can be printed with appropriate values for both images.

The present invention can be variously modified without being limited to the above embodiments. For example, one A
The pre-exposure unit 23 can be arranged at different positions for each exposure frame 21 of the PS film. Also in this case, the position of the pre-exposure unit 23 can be known by the recording unit 27, and a good photograph can be obtained. or,
As the print size, a size other than the classic, high-definition, and panorama may be used.
