  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an image processing apparatus to which the present invention can be applied. Reference numeral 100 denotes an operation unit having keys for inputting instructions to the image processing apparatus and a display unit for displaying various information. Reference numeral 101 denotes a scanner unit as a reading unit that reads an image of a document and outputs it as electronic data. Reference numeral 107 denotes a printer unit as an image forming unit, which is a known electrophotographic printer in the present embodiment, but may be an ink jet type or another type of printer. Reference numeral 103 denotes a CPU as control means for controlling the entire image processing apparatus and performing various image processing. Reference numeral 102 denotes a RAM as a storage unit that stores an image read by the scanner 102, stores an image before being output to the printer unit 107, and functions as a work area of the CPU 103. A ROM 106 stores a control program for the CPU 103, an image processing program, and the like. 104 is a data storage unit that is stored with Scripture source information, etc. out below, has a hard disk drive HDD. The storage unit 104 may be stored in the image processing apparatus main body, or may be externally communicated with the image processing apparatus main body. 105 is an input device for adding the output material (scrap) document information such as the output canon source information. Usage will be described later.

Next, the overall operation will be described. Each document read as image information by the scanner 101 by the operation of the operation unit 100 is first stored in the RAM 102. Next, character string feature information is detected based on the image data stored in the RAM 102. Although the CPU 103 executes the detection of the character string feature information, it may be detected by providing a dedicated circuit. The feature information will be described later. Characteristic information string for each output of the canon source string in the storage unit 104 is registered in association with Scripture source information out, it is collated with the feature information of the detected character string is performed. If there is a match between the detected characteristic information of a character string in the feature information of the character string registered in the storage unit 104, document information such as the output Dian source information of the document is obtained and stored in the RAM102 . Note that a memory different from the RAM 102 may be provided and the source information may be stored therein. Thus, CPU 103 also functions as detecting means, acquiring means for acquiring output Dian source information for detecting the characteristic information of a character string.

On the other hand, the detected if left Dian source information corresponding to the characteristic information of a character string is not registered in the storage unit 104, the user inputs the numeric source information out using the input device 105, input comes Dian source information Is stored in the RAM 102. The input device 105 may also be used as the operation unit 100.

Then CPU103 transfers and Dian source information out with image data stored in the RAM in the printer 107. As a result, scrap canon source information out by the printer 107 is added is generated.

  Next, a method for collating the read image information data with information registered in the storage unit 104 will be described with reference to FIGS. 2, 3, and 6.

In FIG. 2, the character string 1 is a Japanese horizontal character string, and the character string 2 is an English character string. Characteristic information indicating the characteristics of the document such as the character size, character spacing, line spacing, and density contrast between the image part and the non-image part is registered in the storage unit 104 as image information. ing. Incidentally, the feature information, publications and are different for each newspaper, are registered in association with a plurality of exit canon source information.

  FIG. 3 is a diagram illustrating the read contents of the character string information. First, the character height of each line: h, the length of each line interval: hg, the character width of each line: w, and the character interval of each line: wg are read to determine whether the writing is vertical or horizontal. For vertical writing, the column length: vp is obtained, and for horizontal writing, the row length: wp is obtained and registered in the RAM 102. At this time, if the character width w of each line is the same, that is, if w1 = w2 = w3 =... = WN, it is determined that the character string is Japanese, and if it is horizontal writing, the number of characters in the line is obtained. If it is vertical writing, the number of characters in the column is obtained and registered in the RAM 102. On the other hand, in Western languages such as English, character spacing and word spacing are adjusted on each line, so the number of characters per line is not constant. In this case, the paragraph width: wp and the paragraph spacing wpg It is obtained and registered in the RAM 102.

  Whether the writing is vertical or horizontal in Japanese is determined by the size of hg and wg. When hg is larger than wg, horizontal writing is determined. When wg is larger than hg, vertical writing is determined. In the character string 1 of FIG. 3, since it is horizontal writing, 10 which is the number of characters in the line is registered in the RAM 102.

  In Western languages such as English, the types of characters are less than in Japanese, so feature data of each character is stored, and all characters are in Western European characters such as English by a well-known character recognition process. It can also be judged whether it is not Japanese by judging whether it exists.

  FIG. 6 shows a plurality of newspapers (A newspaper, B newspaper, C newspaper), a plurality of information magazines (D magazine, E magazine, F magazine), an English newspaper (G newspaper), and an English information magazine (H magazine). It is a figure which shows the various parameters which are the characteristic information of a character string. The parameters include the density ratio between the image part and the non-image part, the number of characters in each line, the character height h in each line, the length hg in each line interval, the character width w in each line, the data wg in each character interval in each line, This data indicates vertical writing or horizontal writing. Also, the density ratio between the image area and the non-image area is the optical reflection density when the document is read. By utilizing the fact that the density ratio differs depending on the paper quality of newspaper or information magazine, more accurate document information A distinction can be made.

  The CPU 103 collates with the read document image information based on the data of FIG. 6, and determines document information such as document source information.

Figure 4 is a flowchart showing a procedure of a copying process including the determination processing exits canon source information. This will be described with reference to the flowchart below. First, when there is a reading instruction from the operation unit 100, the CPU 103 reads an image of a document by the scanner 101 and stores it in the RAM 102 (S1). The CPU 103 analyzes the image stored in the RAM 102 and obtains the density of the image portion / non-image portion of the document (S2). Subsequently, the CPU 103 obtains the character height of each line, the length of each line interval, each character width of each line, and each character interval of each line (S3 to S6). The CPU 103 determines whether the document of the document is vertical writing or horizontal writing based on the obtained various parameters, and determines the column length if it is vertical writing and the row length if it is horizontal writing (S7).

  Next, the CPU 103 determines whether or not the character widths of the respective lines are the same (S8). If they are the same, the CPU 103 determines that the read character string is a Japanese character string. If it is vertical writing, the number of characters in the column is obtained and stored in the RAM 102 (S9). On the other hand, if each line has a different character width, the CPU 103 determines that the read character string is a character string in a Western European language such as English, obtains the paragraph width and the interval between the paragraphs, and stores them in the RAM 102. (S10, S11).

  The CPU 103 collates the character string characteristic information (parameters) obtained so far with the data stored in the data storage unit 104 (S12), and determines whether the corresponding data is registered in the data storage unit (S13). .

Then, if corresponding data is registered, CPU 103, the identify source source information of the document (S14), and outputs the added specified output Dian source information to the original image (S15). That is, the output product leaving Dian source information is added is obtained.

On the other hand, if the corresponding data is not registered in S13, the CPU 103 inquires of the user whether or not to newly register the data using the operation unit 100, and determines the input of the answer (S16). When an instruction to register is input, the CPU 103 waits for input of document source information from the operation unit 100 and registers it in the storage unit 104 (S17). Then, CPU 103 may additionally and outputs document information input (such as output Dian source information) on the document image (S15). That is, the output product leaving Dian source information is added is obtained. If an instruction not to register is input in S16, the CPU 103 outputs a document image without adding source information. That is, the output product leaving Dian source information is not added is obtained.
