In the case where there is only a black and white binary image, the first block 40 may be omitted and the digital signal BK and the video control signal D may be directly input to the second block 50.

At this time, the whole memory 31 and the partial memory 34 store the binary image signal BK of 256 gradations, but the whole memory 31 has the second block 50 not processed by the third block 60. While temporarily outputting the output from the printer to the plotter unit 13 or the network side, the editing processing unit 32 is provided in the partial memory 34 with the identification corresponding to the marking unit in the monochrome image data sent from the second block 50. A region surrounded by the luminance or the specific density is detected, a partial region surrounded by the marker is cut out and extracted, and the read image (partial region) processed by the third block 60 is stored and extracted. The recognition processing unit 33 uses a known OCR (Opti
The keyword recognized by the cal character reader is output to the plotter unit 13 or the network side while being temporarily stored in association with the read image.

At the same time, after confirming that the number of areas (number of detections) detected by the edit processing unit 32 does not exceed the upper limit number (set number) set in the RAM 23 (step P).
3) The read image is input to the edit processing unit 32, and marker detection is performed in real time to detect an area surrounded by image data of specific luminance or specific density corresponding to the marking part in the image data of 256 gradations. (Step P
4) Write the read image of the partial area to the memory 34 and send it to the HD 15 to store the read image in association with the entire read image (step P5).

The read image in the partial memory 34 is subjected to gamma processing by a gamma processing circuit 61, gradation processing by a gradation processing circuit 62, and binarization processing by a binarization circuit 63 in a third block 60. Then, the recognition processing unit 33 performs character recognition by OCR processing, extracts keywords that are repeatedly used, etc., sends them to the HD 15 and stores them in association with the entire read image (step P7).

Thereafter, when it is confirmed that the document scanning is continuing (step P8), the editing processing unit 3
Increment the number of detection areas by 2 (step P
9), this process is repeated.

When the number of areas detected by the editing processing unit 32 exceeds the number of areas set in the RAM 23 or when the scanning of the original is completed, the process of extracting a partial area of the read image is completed (step P3, P8).

After the end of the series of copying operations, the CPU
Reference numeral 21 denotes a file list in which data evacuated to the HD 15 is collected as one document, for example, as shown in FIG. 4, a header section describing various settings of the copied document, and the entire black-and-white read image as copy data. A file list composed of an image data file list listing the files of the above, and a feature data file list listing the files of the partial image data of the read image as the thumbnail images of the marked locations and the extracted keyword data files And attaches the data to the HD 15 and attaches the network card 17 at a preset time.
To the file server device 100 via the. In addition,
If the edit processing unit 32 does not have a function of limiting the number of marker areas when creating this file list (unset),
The CPU (restriction unit) 21 restricts the number of characteristic data files to be listed (listed) in the file list and transmitted (transferred) to the file server apparatus 100 in accordance with the default number of marker areas set in the RAM 23.

On the other hand, the file server 100

By performing operations and the like in accordance with an application program read from the hard disk device 103, the system can be used as a system for performing various processes such as creation of documents and images. / F circuit 109
The terminal transmits and receives data to and from another terminal device such as the copying machine 10 connected via the PC, and functions as a file server of the filing device.

The CPU 101 receives the same image as the read image processed by the copying machine 10 via the I / F circuit 109, sends it to the IMS 104 constituting the storage means, and stores it as it is. The conditions, thumbnail images, and keywords sent from the machine 10 attached to the entire read image are included in the IMS1 together with the file list.
04.

Then, the file server device 100
The CPU 101 operates the IMS1 in response to a request from the user.
One or both of the thumbnail images and / or the keywords stored in the
For example, when a processing condition or the like is input, the image is narrowed down to only one that satisfies the condition, and a stored image selected from the selected is read out from the IMS 104 and displayed and output. The data can be reused, for example, by transferring the data to a connected plotter device or the like to record and output the data and confirming the contents. That is, the CPU 101
Constitute the management means. The stored image can be reused, such as being temporarily stored in the hard disk 103 while being digitized and processed.

As described above, in the present embodiment, the read image processed by the copying machine 10 includes a thumbnail image which is a read image of a partial area marked in the document and a keyword recognized from the partial area. The image can be transferred to the file server device 100 and can be effectively used when the read image is recalled by the file server device 100. Also, at this time, the number of areas to be extracted for thumbnail images / keywords is limited to a set number, and the number of areas to be extracted is made appropriate to avoid burdening image extraction and keyword recognition processing. The communication load when transmitting to the file server device 100 does not occur.

Therefore, in the read image managed by the file server apparatus 100, a portion designated by a marker is displayed and output as a thumbnail image, or a keyword extracted therefrom is displayed and output to select a target processed image. For example, by making a thumbnail image of the whole processed image, a characteristic mark or the like is too small to be indistinguishable, or a keyword without a characteristic is not listed, and the content of the original is not changed. Can be easily selected and reused by appropriately expressing.

In the present embodiment, a part of the read image surrounded by the marker is used for both the thumbnail image and the keyword. However, it is possible to use either the thumbnail image or the keyword depending on whether or not the character can be recognized. Alternatively, the marker may be selectively used depending on the color of the marker. Further, in addition to extracting the area specified by the marker, for example, the area may be set in advance so as to extract a title or a mark displayed at a specified position. Needless to say, the recognition and extraction of the keyword may be performed on the file server device side.

A case of a filing apparatus for storing and storing a read image will be described. Images and keywords extracted from a processed image are printed out separately.
You may make it available as a summary of a document.

[0048]

According to the present invention, the read image of the set area or the designated area in the original is extracted and attached to the read image of the entire original, so that a part of the image appropriately representing the contents of the original is printed. It can be attached to the read image of the entire document to be processed or filed, and represents the content of the document optimally, for example, as a thumbnail image, or by recognizing a keyword, printing on the first page, or storing and reading It can be used as specific information when selecting an image.

If the number of areas to be extracted from the read image can be designated, or if the number exceeds the designated number, the extraction control or the transfer control is restricted, so that the load applied to the apparatus that performs the control becomes excessive. That can be avoided.

Therefore, the contents can be easily grasped from a part of the image attached to the read image, and the read image can be easily selected and specified at the time of reuse.
