Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing device equipped with an image storage device.

[Prior Art] Image editing devices that read various images such as documents and drawings and edit those images are known. in general,
Such an image editing device is provided with a hard disk device or the like as an image storage device in order to store read images and edited images.

Furthermore, such image editing devices have a built-in CPU and a general-purpose DOS (Disk Operation System).
stem) to process and manage various data.

In this case, the amount of image data is extremely large, and if the image data files stored in the hard disk drive are managed by a general-purpose DO8, there will be problems such as a long access time to the disk, and efficient processing will not be possible. I can't do it.

To improve this, software such as a direct ■/O file control process, which operates independently of the general-purpose DO5, has been installed exclusively for accessing the disk. The direct I/O file control process is used when storing and reading image data files on the hard disk drive, while the direct I/O file control process is used when storing and reading various data files other than image data on the hard disk drive. In this case, the general-purpose DO8 was used.

[Problems to be Solved by the Invention] However, in this case, the direct I/O file control process only has the function of reading and writing image data files to a specific hard disk device, and the general-purpose DO3 has Since the image data file was not managed, it was not possible to read or write to the hard disk device.

For this reason, for backup of image data.

Optionally perform transfer processing to transfer the image data stored in the hard disk device to another disk device such as a floppy disk device, or conversely from another disk device to the hard disk device, as necessary. The problem was that I couldn't do it.

The present invention solves the above problems and provides an image processing device equipped with an image storage device that can arbitrarily transfer image data between one image storage device and another image storage device. With the goal.

[Means for Solving the Problems] To this end, the present invention provides a means for directly reading and writing data to and from a specific image storage device in the form of an I/O file, operating independently of a general-purpose disk operating system. , operating under a general-purpose disk operating system, comprising means for reading and writing data to and from other image storage devices in a conventional file format, and a plurality of image data storage devices for storing image data; The image data obtained through image processing is written to a specific image storage device in the above-mentioned direct I/O file format as in the past, while the image data is written to an arbitrarily specified direct I/O file from that specific image storage device. In addition to reading out the image data in the format,
Image data transfer means writes the image data in a normal file format to another image storage device, and reads the image data in a normal file format from the other image storage device.

The present invention is characterized by comprising an image data transfer means for directly writing the image data in the I/O file format to the specific image storage device.

[Function] The two transfer means described above make it possible to arbitrarily transfer image data between one image storage device and another image storage device.

One module is a logical interface located between the user interface and the physical interface.

The X I O 5201g controls physical hardware, and access to the hardware from the various modules described above is always performed via this.

By the way, the BD OS 201d has a function of reading and writing data in a normal file format to the hard disk drive device 11/O and the floppy drive device 111. However, when reading and writing huge amounts of data such as image data, the direct I/O file control process 203 takes time and is inefficient.
BD O5201d is independent and direct X I OS
Works on 201g, hard disk drive device 11/O
Image data can be read and written at high speed in a direct I/O format.

With the above configuration, the original image is read by the image scanner/O4, and the obtained image data is temporarily stored in the bitmap memo January 08.

For example, only a necessary portion of the image data is extracted and compressed by a single image data compression/reproduction unit/O9, and then stored in the hard disk drive unit w1/O.

By the way, the data recording area on the disk of the hard disk drive device 1/O is as shown in FIG. 3(a).
It is divided into a system file area a managed by the BDO 8201d and a direct I/O area managed by the direct I/O file control process 203.

In this embodiment, the image data is directly stored in the I/O file format on the disk of the hard disk drive device 1/O. In this direct I/O file format, for example, the file name "XXX" is stored in the system file area a.
While a file with a specific extension such as "FSB" is created, the image data is directly recorded in the data section of the I/O area, and the index information for reading it is stored in the index section. recorded in

FIG. 3(b) shows the index information stored corresponding to the above "XXX, FSB" file. In FIG. This indicates in which unit the information is recorded. The start address indicates the first cylinder number, track number, and sector number in which the data block of image data is located. In addition, the block length indicates the amount of data,
The index key is code information set for each data block of image data.

When the image data is stored in the hard disk drive device 1/O, the XI O8201g is directly activated by the direct I/O file control process 203 without the intervention of the BD OS 201d, and the Image data is stored in I/O file format.

Next, for example, when recording the accumulated images with a laser printer/O6, the direct I/O file control process 203 directly prints the
The I/O 5201g is activated, the direct I/O file is read, and the accumulated image data is retrieved.

The image data is then processed by the image data compression/reproduction unit/
After the data is expanded and reproduced into the original image data by O9, it is transferred to the laser printer/O6 and the image is recorded.

In such image processing, when management information other than image data is stored in or read from the hard disk drive device 1/O or floppy drive device 111, it is executed by the BDO 5201d.

Next, the operation of transferring image data from the hard disk drive device 1/O to the floppy drive device 111 for backing up the image data will be described.

FIG. 4 shows this transfer process.

This process is executed under the control of the file transfer control process 204, and can be roughly divided into a process 3 that is executed under the direct/○ file control process 203 and reads the I/O file directly from the hard disk drive 1/O.

Next, it is checked whether an index file for recording image data has been created on the floppy disk of the floppy drive device 111 (process 302a), and if no index file has been created (N in process 302a). , an index file is created in a predetermined format using the BDOS 201d (processing 302b). On the other hand, if an index file has already been created (Y in process 302a), the file is opened (process 302c).

After this, in the above index file, the above flxXX

Thereafter, the file on the floppy disk is closed (process 302h), and the direct I/O file on the hard disk is closed (process 301f).

Then, if there is any other image data that you want to transfer (processing 30

When executing this process, the operator sets the file name and index key to be read out of the image files created in the transfer process of FIG. 4 through predetermined operations.

As a result, this device first opens the index file in the floppy disk device 111 (process 401a), and then inputs the set file name and index key (process 401b, process 401b).
Next, image data corresponding to the index key is read out (processing 401d).

Then, the read image data is transferred to the bitmap memory/

Thereafter, the direct I/O file on the hard disk is closed (process 402d), and the file on the floppy disk is closed (process 401f).

Next, if there is more image data to be transferred on the floppy disk (Y in process 403), the data transfer is executed in the same way (proceed to process 401a), while once all data transfer is completed (N in process 403), This transfer process ends.

As described above, in this embodiment, the hard disk drive device 1/O for storing normal image data and the floppy drive device 1111 for backing up one image data are provided, and the floppy drive device 1111 operates independently of the BDO 5201d. , means for directly reading and writing data to and from a hard disk drive device 1/O in an I/O file format;
O5201d operates under the O5201d and reads and writes data to and from the floppy drive device 111 in a normal file format, and the image data obtained by image processing is transferred to the direct I/O as before. It is written to the hard disk drive device 1/O in file format.

Then, a transfer operation is performed in which image data in an arbitrarily specified direct I/O file format is read from the hard disk drive device 1/O and written to the floppy drive device 111 in a normal file format, and the floppy drive device 111 The file transfer control process 204 executes a transfer operation of reading out image data in a normal file format from a file and directly writing it to the hard disk drive device 1/O in an I/O file format.

As a result, one image data can be arbitrarily transferred between the hard disk drive device 1/O and the floppy drive device 111, and image data can be backed up freely, improving data management and maintenance efficiency. improves.

Note that in this embodiment, edited image data is normally stored in the hard disk drive device 1/O and backed up to the floppy drive device 111 as necessary, but both may be hard disk devices, or optical disks or other Of course, the storage device may be used as a storage device.

It goes without saying that the present invention is not limited to image editing devices, but can be similarly applied to various image processing devices that process image data and store it in a storage device.
