BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic image output method and apparatus, and more particularly to a case where a photographic image recorded on a photographic film is printed out as a photographic print and the photographic image data is stored as a file for later use. The present invention relates to a photographic image output method and apparatus.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been known a photo finishing system that reads an image of each frame of a photograph recorded on a photographic film (hereinafter simply referred to as film) by a film scanner, obtains image data, performs necessary image processing, and outputs it as a photographic print. It has been.
[0003]
On the other hand, photographic image data is stored as an image file on removable media so that it can be used on a personal computer, etc., but this is a service that is generally performed only for some photos selected by customers. In addition to the above-described photofinishing system, equipment such as a scanner and an image processing apparatus is usually provided. At this time, in order to provide a high-quality image file that can be printed out as a photographic print as well as displayed on a monitor, it was necessary to prepare an expensive one as the above equipment, so the price of the file output service is It was not necessarily cheap.
[0004]
[Problems to be solved by the invention]
In recent years, with the rapid spread of personal computers, the demand for file output services to the removable media as described above has increased. Also proposed is a service form in which all customer photos are stored and stored as image files on a server computer (hereinafter referred to as an image server) having a large capacity disk installed in a laboratory and used for reprinting. ing. Therefore, there is a demand for a method that can efficiently output a file of photographic image data at a lower cost.
[0005]
Also, from the viewpoint of the image quality of a photographic image, it is not preferable to perform print output and file output separately as in the prior art. When processing is performed separately, the reading conditions and image processing conditions do not always match. For example, when a print is created from an image file, the same finish as that of simultaneous printing is not always obtained, and the same finish is obtained. For this reason, there is a disadvantage that adjustment by trial and error must be performed.
[0006]
SUMMARY OF THE INVENTION In view of the above problems, the present invention efficiently outputs an image file capable of obtaining a desired finish at the time of printing when a photographic image recorded on a film is printed and saved in a storage medium as an image file. It is an object of the present invention to provide a photographic image output method and apparatus that can be provided to customers.
[0007]
[Means for Solving the Problems]
According to the photographic image output method of the present invention, a plurality of photographic frame images recorded on a photographed and developed photographic film are sequentially pre-scanned by a film scanner having an automatic film feeding function to obtain a plurality of pre-scan image data. And
Based on the plurality of pre-scan image data, set a reading condition when performing a fine scan,
Based on the set reading conditions, a plurality of fine scan image data is obtained by sequentially fine scanning the frame images of the plurality of photos with the film scanner,
For each of the plurality of fine scan image data, image processing suitable for print output and file output is performed,
The plurality of fine scan image data subjected to image processing suitable for the print output is printed out by a printer, and the plurality of fine scan image data subjected to image processing suitable for file output is determined in advance. A file is output to a storage medium.
[0008]
In the photographic image output method according to the present invention, the prescan and the fine scan may be performed only on an image of a desired frame among photographic frames recorded on the photographic film.
[0009]
In the photographic image output method according to the present invention, the print output and the file output of each image data may be performed simultaneously, and the print output and the file output of each image data are alternately performed. You may make it carry out.
[0010]
A photographic image output apparatus according to the present invention sequentially pre-scans a plurality of photographic frame images recorded on a photographed and developed photographic film while automatically feeding the photographic film to obtain a plurality of pre-scan image data. A film scanner that fine scans the images of the frames of the plurality of photos to obtain a plurality of fine scan image data based on predetermined reading conditions,
Based on the plurality of pre-scan image data, a reading condition setting unit that sets the predetermined reading condition when performing fine scanning;
Image processing means for performing image processing suitable for print output and file output for the plurality of fine scan image data,
A printer that prints out the plurality of fine scan image data subjected to image processing suitable for the print output as a photographic print;
By operating in parallel with the printer, to the predetermined storage medium of the plurality of fine scan image data subjected to image processing suitable for outputting the file during printing of the plurality of fine scan image data by the printer And a file output means for performing the file output.
[0011]
In the photographic image output device of the present invention, the film scanner performs the pre-scan and the fine scan only on a desired frame image among photographic frames recorded on the photographic film. It is good.
[0012]
In the photographic image output apparatus of the present invention, the print output of each image data by the printer and the file output by the file output means may be performed simultaneously, and the print of each image data by the printer. The output and the file output by the file output means may be alternately performed.
[0013]
According to another photographic image output method of the present invention, a plurality of photograph frames recorded on a photographed and developed photographic film are sequentially read by a film scanner having a film automatic feeding function to obtain a plurality of image data. The plurality of image data are printed out by a printer and output to a file on a predetermined storage medium. That is, both the print output and the file output of photographic image data are to be performed by one film handling.
[0014]
The reading is preferably performed only on an image of a desired frame among photographic frames recorded on the photographic film. The “desired frame” means a normal frame excluding, for example, out-of-focus, extreme under and over frames. Also, with APS (Advanced Photo System), etc., the photographer can determine whether printing is necessary before reading the film and magnetically record the information on the film. Some have a function of reading this information and automatically skipping unnecessary frames. That is, in such a case, the “desired frame” means a frame in which information indicating that printing is necessary is recorded on the film.
[0015]
As a specific example of the above method, for example, the image data obtained by one reading is simultaneously or alternately printed / filed, or the first reading is performed by one-way film feeding. There is a method that prints out all image data, then scans the film for the second time in the reverse direction, and outputs the read image data to a file (of course, output the file before printing it) May be output).
[0016]
As a general film reading method, there is known a method of performing a fine scan for obtaining image data of a desired resolution after performing a pre-scan to determine a reading condition and the like. The term “reading” once means reading once to obtain image data having a desired resolution, and the prescan is not counted.
[0017]
Also, when image processing is performed on image data before print output and file output, it is desirable to perform different image processing depending on the image quality required for the photographic image output in each form.
[0018]
According to another aspect of the present invention, there is provided a photographic image output device for performing an output process according to the above-described method. A film scanner that reads a plurality of image data by sequentially reading while automatically feeding, a printer that prints out the plurality of image data as a photographic print, and a printer that operates in parallel with the printer, File output means capable of outputting a file of the image data to a predetermined storage medium during print output.
[0019]
In this apparatus, in the case of performing print output / file output after performing different image processing on the image data, two image processing means are provided to perform image processing for print output and image processing for file output, respectively. One image processing unit that can adjust the processing conditions by changing parameters or the like may be provided, and image processing may be performed by changing the parameters for print output or file output as necessary.
[0020]
Note that the photographic image output method and apparatus of the present invention is intended for a case where a large amount of film must be processed quickly by utilizing an automatic film feeding function, such as a photo finishing system installed in a laboratory or the like. Yes. In other words, for example, in a configuration in which a film scanner and printer are connected to a personal computer, the film is manually set and scanned while selecting a frame, and then it is output to a file and then printed. It is assumed that the image data is output one after another in the order of reading, and the next data reading process is performed while the output process is being performed. In other words, as a system configuration, for example, as in a conventional laboratory auto printer, the read image data is alternately written in the two frame memories, and the image data is read out from the unwritten frame memory and output. Presupposes a simple configuration.
[0021]
【The invention's effect】
According to the photographic image output method and apparatus of the present invention, a plurality of photographic image data obtained by one film handling is printed out by a printer and output to a predetermined storage medium. By effectively using the equipment, both print creation and image file storage can be efficiently performed at low cost.
[0022]
At this time, performing print output and file output by one film handling means that when image processing is performed, processing is performed based on the same standard. When printing out, the desired finish can be obtained without adjustment by trial and error.
[0023]
DETAILED DESCRIPTION OF THE INVENTION
The photographic image output method and apparatus of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention. This is a photofinishing system installed in a lab or the like, and has a function of outputting photographic image data output as a simultaneous print as a file to a removable media or a lab image server.
[0024]
Similar to the conventional photofinishing system, this system reads all normal images except for out-of-focus, extreme under and over frames, etc., recorded on the film 1, and digital image data obtained by this is read. Is stored in the frame memory 2. Alternatively, when reading an APS film, as described above, only print-needed frames may be read based on information indicating the necessity of printing magnetically recorded on the film.
[0025]
Reading is performed by performing two scans of pre-scan and fine scan for each frame. Pre-scanning is performed to set optimal reading conditions, and image data obtained by fine scanning is used for output.
[0026]
At this time, as shown in FIG. 3, the film may be fed for one frame after performing the pre-scan and fine scan for each frame. However, as shown in FIG. In parallel, reading can be performed in about half the time of the method of FIG. Alternatively, as shown in FIG. 5, first, the film is sequentially sent in one direction and only pre-scanning is performed on all frames, and then the film is sent in the opposite direction to perform fine scanning.
[0027]
The image data read in this way is stored alternately in the two frame memories 2a and 2b. This is because the image data in the other frame memory is output while the read image data is written in one frame memory, so that the reading process and the output process can be performed in parallel. It is to do.
[0028]
Image data taken out from the frame memory 2 for output processing is processed by the two image processing means 3a and 3b, respectively. At this time, the processing by the two image processing means and the subsequent output processing are performed simultaneously (in parallel) for each image data. When both processes are completed, the frame memory is switched, and the next image data is read into the two image processing means.
[0029]
The image processing performed by the image processing means 3a and 3b is, for example, correction of color and gradation, but the processing of the two image processing means differs depending on the output purpose of the image data. For example, the image processing means 3b performs a process for improving the image quality when the image data is recorded on a photographic paper as a photographic print, and the image processing means 3a makes the image data displayed on the monitor of the personal computer easy to see. Image processing is performed. However, even if different image processing is performed, the processing performed by the image processing means 3a and the processing performed by the image processing means 3b can be associated with each other, unlike the case where the image processing is performed by different apparatuses. When the file is printed out later, the image processing to be performed can be uniquely determined from the association.
[0030]
The image data processed by the image processing unit 3a is stored in the storage medium 6 as an image file compressed by the compression unit 4 and compressed. On the other hand, the image data processed by the image processing means 3 b is printed out by the digital printer 5.
[0031]
In the embodiment described above, file output and print output are performed simultaneously for each image data. Next, for the embodiment in which file output and print output are alternately performed for each image data, FIG. This will be described with reference to FIG. The film reading mode in the embodiment of FIG. 2 is the same as that of the embodiment of FIG.
[0032]
The embodiment of FIG. 1 includes the image processing means 3 for file output and print output, respectively, but the embodiment of FIG. 2 has only one image processing means, and this image processing means When the processing path is switched to the compression means 4, image processing for file output is performed, and when the processing path is switched to the digital printer 5, print output processing is performed.
[0033]
In the embodiment of FIG. 2, file output and print output may be alternately performed for each image data. For example, after image data of all frames read by sending a film in one direction is output to a file, The processing path may be switched, and then the film may be sent in the opposite direction to read each frame again to print out the image data.
[0034]
Here, in implementing the present invention, whether to adopt the configuration of FIG. 1 or FIG. 2 may be determined in consideration of the capabilities of a film scanner or a digital printer. For example, when it takes a long time to read by a film scanner, there is a high possibility of waiting in the output process. Therefore, it is sufficient to switch the outputs alternately without providing two image processing means. That is, it is desirable to select a form that maximizes the usage rate of each facility.
[0035]
When file output and print output are performed by the photographic image output method and apparatus according to the present invention, the file name of the image file is assigned to the back of the simultaneous print 9 or each frame of the index print 10 as shown in FIG. It is desirable to record it below. Thereby, for example, when a request for reprinting is received, the search of the image file 8 stored in the image server 6 of the laboratory is facilitated, and a quick service can be provided.
[0036]
If a device such as the one described above is installed in a laboratory or the like as an alternative to a conventional photofinishing system, not only print output but also file output is performed at a cost comparable to that required for conventional print output. It is possible to provide an inexpensive service to the customer.
