Abstract

PURPOSE:To attain the alternation of a code which shows the trimming information for printing by recording the code in recording medium other than a film before printing process. CONSTITUTION:A memory pack 5 is provided on a camera body B freely attachably and detachably. Prior to photographing, a printing magnification is set by operating a printing magnification setting switch 3. When a shutter releasing button 6 is pushed in this state, the printing magnification is recorded in the memory pack 5. A photographed film is guided to a printing machine and trimming printing is automatically executed based on the trimming information recorded in the memory pack 5. In the case of correcting the trimming information, novel trimming information is recorded in the memory pack 5 by specifying a frame which desired to be corrected and operating the printing magnification setting switch 3 and a data change over switch 4. Therefore, the trimming information can be easily corrected because the code is recorded in the memory separately from a negative film.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a photographic printing method, and more specifically to a photographic print that can be printed using negative film taken with a normal lens as if it were taken using a telephoto lens. Regarding the method.

[Conventional technology]

Conventionally, a photographic printing method is known in which a photographed film is enlarged and printed using a trimming method to obtain a print similar to that obtained by using a lens with a longer focal length than the used lens.

Furthermore, in such photographic printing methods, a method has been proposed in which a predetermined code is attached to the vicinity of frames of negative film that require trimming to distinguish them from other frames (Japanese Patent Laid-Open No. 59-79236). issue).

However, in these conventional techniques, the code allows the user to select either a normal full print or a trimmed print, but since the code is recorded on the negative film, once such a selection is determined, it cannot be changed later. It was impossible. For example, a camera user's initial request for a cropped print may be changed to a full print. Or, conversely, there may be cases where an entire print, originally desired, is changed to a trimmed print. However, in the conventional technology, such changes cannot be made, and improvements have been desired.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and instead of recording the code on a part of the negative film, it is recorded on a rewritable recording medium such as a memory, so that the code can be used as needed. The purpose is to make it possible to change the trimming information and the like easily.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

° Fig. 1 shows an example of a negative film used for making photographic prints of the present invention, where l is a negative film, and 2 is a plurality of holes perforated at regular intervals on both ends of the negative film l in the width direction. Perforations installed, F1~F3
is a frame exposed by an aperture of a camera (not shown). Figure 2 is a schematic perspective view of the camera used in the present invention, where 2B is the camera body, 3 is a print magnification setting switch for setting the print magnification during trimming, and 4 is a print switch for changing input print data. 5 is a data change switch, 5 is a memory pack detachably provided in the camera body B, 6.7 is a publicly known shutter release button, a photographing lens barrel, and 10 is a counter set switch for changing the settings of a film counter, which will be described later. . FIG. 3 is a schematic block diagram showing the circuit of the camera used in the present invention, and 8 is a CP built in the camera body B.
U, the CPU 8 has the print magnification setting switch 3.
In addition to the print data change switch 4, a release switch 6a that is turned on by pressing the shutter release button 6, a known film counter 9 that counts the number of frames on the film, and a film counter 9 that is used when correcting trimming information are set. A counter set switch IO for resetting is connected. Furthermore, the memory back 5
E” F ROM.

Built-in memory such as SRAM, CPU8
Each piece of information from is stored in code.

The photo printing method of the present invention having the above configuration will be sequentially explained below.

For example, when printing frame F1 in Fig. 1, consider the case where the print magnification is set to high (for example, to obtain a trimmed print p+ (Fig. 5), which is an enlarged print with the area shown by the broken line of frame F1 trimmed). Prior to shooting, operate the print magnification setting switch 3 to set the print magnification to the desired value.In this state, when the shutter release button 6 is pressed, the release switch 6
a is turned on, and the set print magnification is set to CP.
It is recorded in the memory back 5 via U8. FIG. 4 shows a simplified flowchart of these operations. When the release switch 6a is turned on at a, the value set in the film counter 9 is displayed at b, and the print magnification value is displayed at c. After each detection, data is written to the memory pack 5 at step d. As will be described later, if it is necessary to change the stored data, press e to operate the print data change switch.

Next, since no trimming is required for printing frame F2, the print magnification can be set to 1/1 and photographed using the same operation as described above.

In this way, the entire print P2 shown in FIG. 6 is obtained. Furthermore, when printing frame F3, panoramic print p3 (7th
Figure). In this case, although not shown, the print magnification setting switch 3 can be used to not only set the print magnification but also to switch to panoramic mode.

The actual printing method will be explained below.

That is, the photographed film and the recording medium storing the trimming information are simultaneously delivered to the laboratory and processed by a known automatic photo printing machine. That is, when the frame F1 is guided to the print position, a corresponding code is detected by a detector (not shown), and the trimming print P1 shown in FIG. 5 is automatically performed. Similarly, the entire print P2 is automatically obtained from the frame F2, and the panoramic print P3 is automatically obtained from the frame F3.

Now, the case of modifying the trimming information will be described below. For example, after setting the print magnification, you change your mind and print the entire image P4 shown in Figure 8 for frame F.
If you wish to obtain the desired image, first operate the counter set switch 10 to specify the frame you wish to correct, instruct the film counter 9 to set the correction location to frame FI, and then set the print magnification using the print magnification setting switch 3. After setting the trimming information to 171, operate the print data change switch 4 to write new trimming information to the memory. In this way, it is possible to modify the code of the trimming information. Furthermore, for frame F3, trimming print P5 shown in FIG.
If you want to obtain a new code, you can use the same procedure to cancel the previous code for the relevant frame F3 and record a new code. After such code correction, a whole print P4 (FIG. 4) is obtained from frame F, and a trimmed print pa (FIG. 9) is obtained from frame F3.

When a frame is set in an automatic photo printing machine in this manner, printing is automatically performed at a larger print magnification than that of other frames according to the trimming information provided by the code. The photographic paper used is generally a standard size paper such as the service version, which is available in rolls, but only those that are to be trimmed and printed are automatically converted to photographic paper of a different size. It may also be possible to print it.

In the above embodiment, the code that can be modified is related to trimming information, but the code that can be modified may be related to other information.

〔Effect of the invention〕

As explained above, the photo printing method of the present invention is a simple method in which a code indicating trimming information etc. is recorded in a rewritable recording medium such as a memory, and the code can be changed as necessary. It has the effect of easily modifying trimming information, etc., and is extremely practical.
