Specified calligraphy and painting image information 3
is read out, this image information is decoded based on the attribute information 5, further reduced to a size that can be displayed on the display screen, and output to the display. When printing is instructed, the decoded image information of the calligraphy and drawings is sent to the printer and printed.

Problems to be Solved by the Invention However, with this configuration, there is a long waiting time from when the reproduction display of the recorded calligraphy and drawings is specified until the calligraphy image is actually displayed. There was a problem in that the waiting time was considerably long in the case of calligraphy and paintings.

The above problem arises for the following reasons. First, a large amount of information is read out from the storage medium in order to reproduce and display calligraphy and drawings, and in the case of large-sized calligraphy and drawings in particular, the amount of information is enormous, so it takes a long time to read out the information. Second, it takes a long time to decode and reduce such a large amount of image information.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an image file device that speeds up the reproduction and display operation of recorded documents and pictures.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides, when recording image information of calligraphy and drawings on a storage medium, reduced image information for display output that is a reduced version of the image information of the calligraphy and drawings. The apparatus includes a means for recording on a storage medium, and a means for reading reduced image information of the calligraphy and drawings from the storage medium and outputting them to a display when an instruction is given to reproduce and display the calligraphy and drawings recorded on the storage medium. It is something.

According to the present invention, with the above-described configuration, the recorded calligraphy and drawings are reproduced and displayed by reading the reduced image information recorded in advance together with the image information of the calligraphy and drawings from the storage medium and outputting them to the display. The amount of information to be read from the storage medium is significantly reduced, the readout time is shortened, and even if reduced image information needs to be decoded, the processing time is shortened, and image information reduction processing is no longer necessary. Therefore, it is possible to greatly speed up the reproduction and display of recorded documents and pictures.

Reference numeral 24 denotes a control section that controls the entire device, and is connected to each section via a bus 25. A keyboard 26 is used by the device user to input information, instructions, and the like.

The operation of the image file device configured as described above will be described below.

First, the operation when recording calligraphy and drawings will be explained. FIG. 2 is a schematic flowchart of this operation.

When the device user instructs the control section 24 to perform a calligraphy/drawing recording operation using the keyboard 26, the control section 24 performs control to perform the following operations. A calligraphy manuscript is read by the scanner 11, and the original image information is sent to the image memory 19 via the scanner interface section 12 and the bus 25.
(step 31). The original image information in the image memo January 9 is displayed on the display 13 by the image reduction unit 23.
Display memory 2 is reduced to a size that can be displayed on
This reduced image information in the display memory 20 is sent to the display 1a via the display interface section 14 and displayed on the screen (step 32).

The user confirms the displayed content and presses keyboard 2 to record.
6 to the control unit 24, the encoding/decoding unit 2
1, the original image information in the image memory 19 is encoded and stored in the encoded information memory 22 (step 33).
. The encoded original image information in the encoded information memory 22 is transferred to the bus 2.
5 and the optical disk deck interface section 18 to the optical disk deck 17 and recorded on the optical disk (step 34). The recording address information at this time is stored in the control section 24.

Next, the reduced image information in the display memory 2o is encoded by the encoding/decoding unit 21, and the encoded information is stored in the encoded information memory 22 (step 35).
. The encoded reduced image information in the encoded information memory 22 is transferred to the optical disk deck 17 via the bus 25 and the optical disk interface unit 18, and recorded on the optical disk (step 36). The recording address information at this time is stored in the control section 24.

The control unit 24 creates management information including the stored recording address information, which is transferred to the optical disc deck 17 via the bus 25 and the optical disc deck interface unit 18, and recorded on the optical disc (step 37). .

As is clear from the above description, in this embodiment, in the case of recording the image information (original image information) of calligraphy and drawings, the means for recording the reduced image information for display output on the storage medium is the control unit 24. This is realized by controlling the functions of the encoding/decoding section 21, optical disk deck interface section 16, optical disk deck 15, etc. necessary for recording original image information.

FIG. 3 shows the recording format of the optical disc, where 38 is an image information recording area and 39 is a management information recording area. In the image information recording area 38, original image information (encoded information) 41 and reduced image information (encoded information) 42 of calligraphy and drawings are sequentially recorded as shown in the figure. In the management information recording area 39, the management information 43 of the recorded calligraphy and drawings is sequentially recorded as shown in the figure.

As shown in FIG. 4, the management information 43 consists of attribute information 44 containing the image size, resolution, and encoding method, and image information recording address information 45. The recording address information 45 includes the original image. Information recording address information 46 and reduced image information recording address information 47 are included. That is, the original image information and reduced image information of one calligraphy or painting are managed in a unified manner.

In addition, in the case of recording calligraphy and paintings, depending on the user, keyboard 2
The keyword input in step 6 is recorded on the optical disk (or another storage device) in association with the calligraphy and drawings, but since this is the same as in the conventional case, the explanation will be omitted.

Next, we will explain the masterpiece of playing back recorded calligraphy and drawings. FIG. 5 is a schematic flowchart of this operation.

When the user uses the keyboard 26 to instruct the control unit 24 to reproduce the calligraphy and drawings and specifies a keyword, the control unit 24 performs control to perform the following operations. The optical disk ticker 18 reads out the management information of the specified calligraphy or drawing from the management information recording area on the optical disk, and this is transferred to the control section 24 via the optical disk deck interface section 18 and the bus 25 (step 51). The control unit 24 specifies the recording address information of the reduced image information included in this management information to the optical disc disk drive interface unit 18 and instructs it to read it, and the optical disc deck 17 reads the reduced image information of the specified calligraphy and drawings. is read from the image information recording area of the optical disc and stored in the encoded information memory 22 via the optical disc deck interface unit 18 and the bus 25 (step 52).
. The control unit 24 specifies the content of the attribute information in the management information to the encoding/decoding unit 21, and the encoding/decoding unit 21 decodes the reduced image information in the encoded information memory 22 and stores it in the display memory 20. This reduced image information is sent to the display 1a via the display interface section 14 and displayed (step 53).
.

In this way, the calligraphy and drawing images are reproduced and displayed by reading out the reduced image information previously recorded on the optical disk, decoding it, and outputting it to the display 13. Since the amount of information is reduced, the readout time and decoding processing time are significantly shortened, and there is no need for reduction processing, high-speed reproduction and display is possible.

Further, as is clear from the explanation up to ξ, in this embodiment, the reduced image information is read out and displayed on the display 1a.
Under the control of the control unit 24, the means for outputting to
, display memory 20, display interface unit 14, and other functions.

Note that even if the image memory 19 has a large amount of original image information so large that the storage capacity is insufficient, it can be reduced if it has been recorded on an optical disk by another similar image file device that does not have insufficient storage capacity. Since the storage capacity of the image memory 19 will not be insufficient for image information,
The playback display can be performed.

If only playback display is specified, the operation will end, but
When print output is specified, the recording address information of the original image information is sent from the control section 24 to the optical disk deck interface section 18, and the original image information is read from the specified recording address by the optical disk deck 17. and stored in the encoded information memory 22 (step 54)
. This original image information is decoded by the encoding/decoding unit 22 and stored in the image memory 19 (step 55), and this original image information is output to the printer 15 via the printer interface unit 16 and printed (step 55). 56)
.

In this embodiment, the original image information and the reduced image information are continuously recorded in the same area on the optical disk, but they may be recorded in separate areas.

Furthermore, the present invention can be similarly applied to an image file device that uses a storage medium other than an optical disk, and an image file device that records image information on a storage medium without encoding it.

Effects of the Invention As is clear from the above description, when recording image information of a calligraphy or painting, the present invention also records reduced image information for display output, which is a reduction of the image information of the calligraphy or painting, on a storage medium. When an instruction is given to reproduce and display a calligraphy or painting, the reduced image information of the relevant calligraphy or painting is read out from the storage medium and output to the display, so the amount of information read from the storage medium for reproduction and display is significantly reduced, and the reduced image information is output to the display. Since no processing is required, this method has the effect of greatly speeding up the reproduction and display of recorded documents and pictures.
