[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image data recording apparatus and method for recording image data on an optical disk and to an optical disk, and more particularly to a system for recording image data obtained from a silver halide photographic film. The present invention relates to a simple image data recording device and recording method, and an optical disk.

[0002]

2. Description of the Related Art In recent years, a so-called photo CD in which image data obtained from a film of silver halide photographic is recorded on an optical disk.
System development is underway. In this photo CD system, the film taken is brought in from the user,
This system is developed to create a silver halide photographic negative or positive film and record the image data obtained from this film on a photo CD. The photo CD on which the image data is recorded is given to the user, and the user sets the photo CD on a dedicated playback device or CD-I player, and easily displays the photographed image on a television monitor or the like for viewing. .
Further, the user performs another image filing or image data processing by reproducing the recorded image data with a CD-ROM device and transferring it to a personal computer.

As a recording medium used in this photo CD system, a write-once CD (compact disc) is used. Image data is recorded by irradiating the recording layer of the write-once CD with laser light to form pits.
Such write-once CDs are made of polycarbonate resin (Polycar
A thin film layer of an organic dye such as cyanine is formed on a transparent substrate molded with a material such as bonate), and this is used as a recording layer. Is formed. Next, the write-once CD has a protective layer formed by thinly coating a resin or the like on the metal reflective layer. Finally, the logo or character of the company that manufactured the write-once CD is printed on the surface of the protective layer ( (Label side).
A photo CD is manufactured by recording image data obtained from a photographic film on a write-once CD created in such a process. Normally, a photo CD is provided to a user with an index print indicating the content of a recorded image attached to a case in order to facilitate classification and storage.

[0004]

However, the photo
An index print is attached to the CD, but the photo
Since there is no indication on the CD itself to identify the recorded content,
When the photo CD is taken out of the case, there is a problem that it is not possible to identify what image data is recorded on the photo CD. Therefore, it is necessary to play back the photo CDs one by one and check the contents of the recorded images. In this case, as the number of photo CDs owned increases, the time required to search for the images of the photos required increases. The trouble was increasing.

In order to classify Photo CDs, it is conceivable to attach a seal to the surface (label surface) of the protective layer of the recorded Photo CD and write the recorded content on the seal with a writing instrument. However, if the writing pressure is increased, the protective layer of the photo CD is weak to the strong pressure, so that the recording layer is damaged, so that there is a problem that the recorded data cannot be reproduced or additional recording cannot be performed. At this time, if you try to remove the sticker from the photo CD due to mistakes in the entry etc.
The recording layer of the CD and the metal reflection layer are peeled off, and the photo CD
However, there was a problem that it became unusable.

The operation of the image data recording system according to the present embodiment having the above configuration will be described below.
4 to 6 show the operations of the image processing device 18 and the print processing device 28 in the form of flowcharts. First, a photographed film is provided by a user, and this film is developed by an existing developing machine, and a photographed image is formed as a negative image on the film. This film is set on the image input device 10.

The image input device 10 scans the set film, reads the image, and transfers it to the image processing device 18. The image processing device 18 inputs the image data transferred from the image input device 10 via the image input processing unit 40 in step 401 shown in FIG. The image input processing unit 40

And record it on a CD. Next, the process proceeds to step 503, and if there is image data to be input next, the process proceeds to step 401, and the processes up to step 503 are repeated. If there is no image data to be input, the operation of the image processing device 18 ends.

On the other hand, in step 504, when the image data for printing is selected, the image data processing section 42 receives the selection signal from the image data selection processing section 48 and converts the image data for printing into the image data for printing. Transfer to section 48. The print image data processing unit 48 writes the print image data into the print frame memory. In this case, if the selected image is one image, data of 2048 × 3072 pixels is written in the frame memory for printing to be used as image data for printing. When a selection signal for printing four frames of images is input from the image data selection processing unit 46 to the printing image data processing unit 48, the printing image data processing unit 48 saves the storage area of the printing frame memory. The image data is divided into four parts, and the low-resolution image data of 1024 × 1536 pixels generated by thinning out in step 403 is written in one area of a frame memory for printing. Similarly, when image data of 1024 × 1536 pixels is generated for the remaining three images, the image data for printing is written to the remaining area of the frame memory for printing, and is used as image data for printing. Next, proceeding to step 505, when all the image data for printing is stored in the area of the frame memory for printing, the data transfer processing unit 50 reads the image data for printing from the frame memory for printing, and Create data. The data transfer processing unit 50 transfers the transfer data to the print processing device 28 via the Ethernet 32 at a high speed.

Next, in step 601, the transferred transfer data is input to the data input processing section 60 of the print processing device 28, and the print image data is reproduced.

In this way, the print image data is converted into YMCK data suitable for printing, and the YMCK data is subjected to processing such as color correction for correcting the color balance of the print recording system. Then step 60
Proceeding to 3, the print data processing unit performs halftone separation processing on each color data of the YMCK data generated in step 602 to generate print data. Next, in step 604, the print data is transmitted from the print data output processing unit 66 to the image printing apparatus 22.
