Abstract

PURPOSE:To increase the number of image files on the whole by inhibiting image data of part of an existent image file on an optical disk from being copied and constituting a new image file only with index data. CONSTITUTION:Image data which are read by a scanner 11 are passed through an image memory 13 and stored on the optical disk by an optical disk drive 15. When an image file 41 is formed of image data (c), part image data (a) of an image file 21 are read out of the optical disk with an indication from a keyboard 16 and confirmed on a CRT display part 17. A process/judgement part 14 refers to an index part 22 to generate a new index part 42. At this time, the judgement part 14 sends an inhibition signal to the drive 15 and takes the image data (b) and (c) out, which are confirmed on the display part 17; and then the index data are added to the index part 42 of the file 41. Consequently, the new image file is constituted only with the index data.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an optical disk device used in personal computers, optical disk systems, and the like.

Conventional technology Conventionally, in this type of optical disc device, when creating a new file using an existing image file on an optical disc, a part of the image data is copied onto the same optical disc again to create a new image file. I was creating it.

Problems to be Solved by the Invention However, in the conventional optical disk device, each time a new image file is created using existing image data, the existing image data is copied and inserted into the new image file. As a result, image data on the optical disc is duplicated, resulting in wasteful storage and poor usage efficiency.

The present invention solves these conventional problems, and aims to provide an optical file device that can increase the overall number of image files stored on an optical disc.

Means for Solving the Problems In order to achieve the above object, the present invention, when the image data to be used already exists on the optical disc, copies the image data to another image file on the optical disc without copying the image data to another image file. A new image file is constructed from only index data.

Therefore, according to the present invention, it is possible to create a new image file without copying part of the image data of the existing image file on the optical disc, thereby increasing the overall number of image files on the optical disc. It has this effect.

Embodiment FIG. 1 shows the configuration of an optical disc device in an embodiment of the present invention. In FIG. 1, 11 is a scanner;
12 is a printer, 13 is an image memory, 14 is a processing/
15 is an optical disk drive, 16 is a keyboard, and 17 is a CRT display section. The image data of the original read by the scanner 11 is input to the image memory 13 and then stored on an optical disk by the optical disk drive 15.

An image file on an optical disc is generally divided into an index section 22 and an image data section 23, like an image file 21 shown in FIG. The index section 22 contains, for example, data indicating an image data start logical block containing actual image data and the block length.

Now, consider creating a new image file 41 from some image data a and b of the image file 21 and some image data C of the image file 31. After instructing the creation of a new image file 41 using the keyboard 16, part of the image data a of the image file 21 is read from the optical disk to the image memory 13 using the optical disk drive 15, and confirmed on the CR7 display section 17. When making this part of a new image file 41, the processing/judgment unit 14 refers to the index unit 22 of the image file 21, retrieves index data such as the image data start logical block and block length, and creates a new image file. 41 index sections 42 are created. In this case, the image data a is processed by the processing/judgment unit 14 so as not to be copied onto the optical disc.
prohibits the optical disk drive 15. Similarly, image data b of image file 21 contained in the optical disk
and extracts image data C from the image file 31,
After displaying and checking on the CR7 display section 17, index data such as the starting logical block and block length of each image data is added to the index section 42 of the new image file 41.

If you want to add new image data that is not stored in the image file, you can create a new image file 41 by reading the image data with the scanner 11 and adding it to the image data section of the image file 41.

It goes without saying that if you know which image data of which image file it is, there is no need to check on the CR7 display section 17, and you can directly instruct it with the keyboard 16 to create a new image file.

Effects of the Invention As is clear from the embodiments described above, the present invention prohibits the copying of part of the image data of the existing image file on the optical disc and creates a new image file using only index data. This has the advantage that the number of image files can be increased overall.
