Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a distributed processing system that performs character recognition on input document data and performs predetermined image processing based on the recognition result.

[Conventional technology]

Conventionally, a character recognition device that performs character recognition has performed character recognition on the input document data as an integrated device that has an image input function that electronically scans a document or the like and inputs document data.

On the other hand, as image processing apparatuses that perform image processing, devices that perform standard image editing or interactive free editing using a P1-MAP display have been developed.

[Problem to be Solved by the Invention] Such a character recognition device may require an image editing function, but incorporating the image editing $1 function described above requires editing without the user performing editing operations. There are problems in that programming for the t1 function is required and the production cost increases by 1~.

In addition, the above-mentioned image processing device may also require a character recognition function, and the character recognition accuracy by the above-mentioned character recognition function needs to be at the same level of accuracy as a dedicated character recognition device.
In many cases, the recognition speed may be slow, and integrating character recognition functions into each image processing device is inefficient in operation, increases production costs, and is often without merit.

The present invention has been made in view of the above-mentioned circumstances, and combines the character recognition function of an existing character recognition device with a plurality of image processing units 11J! An object of the present invention is to provide a distributed processing system in which devices can be shared and a character recognition 11iH device can be used efficiently.

[Means and effects for solving the problem] In the present invention,
Image input processing means comprising an image input section into which image data such as document data, etc., such as a manuscript is inputted, and an image processing section which performs image processing on the document data based on desired image processing contents corresponding to the inputted document data. and data recognition means such as a character recognition unit that recognizes the image processing content of the document data based on the image identification data included in the document data, and data such as an Ethernet that connects the image input processing means and the data recognition means. and a transmission network, and each of the image input processing means transmits image identification data to the Ethernet network 1 to
The data recognition means sequentially transmits the image processing contents corresponding to the image identification data to each of the image input processing means via the Ethernet, whereby one character recognition means can be transmitted to multiple image input processing means. image input processing means can be shared.

[Example] An example of the present invention will be described in detail based on the drawings of FIGS. 1 to 3.

FIG. 1 is a block diagram showing a schematic configuration of a distributed processing system according to the present invention. In the figure, a plurality of image processing devices 118 to 1100 that perform image processing, a character recognition unit @ 12 that performs character recognition, and system controllers 1 to 13 that store data for image processing each have one helanceiver 1.
It is connected to the Ethernet cable 17 via 4a to 14n and 15.16. Each image processing device 11a to 11n
comprises an automatic document feeder, an image input section that reads an image of a document, etc. from the original sent by the automatic document feeder, and digitally inputs the read image, and an image input section that processes the input signal of the digital input. It has an image processing section. As shown in FIG. 2, the input signal includes an identification number data section 18 comprising code information and image identification data for identifying images;
and a target data section 19 having target data (images) to be subjected to image processing corresponding to the image identification data. 17 to the character recognition device 12 to request recognition of the character image. The character recognition device performs character recognition processing based on the image identification data, and returns the recognition result as code information to the image processing device that made the recognition request via the Ethernet. The image processing unit that receives the code information performs image processing with different contents based on the code information.

Next, the operation of the image processing apparatus during data transmission in image processing will be described in detail based on the flowchart v-I shown in FIG. In the figure, first, in each of the image processing devices 11a to 11n, an image input section electronically scans and reads a document (step 101), and sends it to the image processing section as a document input signal. The image processing unit has an identification number data section 18 for identifying the document, and target data to be subjected to image processing corresponding to the image identification data of the identification number data section 18, out of the input signal of the document to be imported. The target data section 19 is extracted (step 102). Next, the image processing device transmits the extracted image identification data of the identification number data portion to the character recognition device 12 via the Ethernet 17 (step 103).

This data transmission employs a packet transmission method, and the image identification data sent from each of the image processing devices is taken into the character recognition device 12 in a predetermined order. The character recognition device 12 performs character recognition processing based on the image identification data, and recognizes each image processing device that has transmitted the image identification data based on the address in the packet set corresponding to the image identification data. The recognition result is sent back as code information to each image processing device that has requested recognition via the Ethernet.

During this time, each image processing device judges whether or not it has received the recognition result (step 104), and when the code information of the recognition result is received and obtained (step 105),
The code information is transmitted to the system controllers 1 to 13 via the Ethernet 17 to request data for image processing corresponding to the code information (step 106).

Upon receiving the code information, the system controller 13 sends image processing data corresponding to the code information to each image processing device.

During this time, each image processing device determines whether or not it has received data for image processing (step 107), and when it receives and obtains data for image processing corresponding to the document number (image identification data) ( Stella 1108) executes image processing to synthesize an image and the image processing data from the target data section 19 of the document and the image processing data (step 109).

Therefore, in the present invention, each image processing device can individually perform image processing with different contents based on the code information received from the shared character recognition device.

〔Effect of the invention〕

As explained above, in the present invention, one existing character recognition device can be shared by a plurality of distributed image processing devices, so the character recognition device can be used efficiently in distributed processing, and the overall system usage efficiency can be improved. In addition to increasing
Manufacturing costs can be reduced.
