When loading an image, the address control 314
The ND image signal 307 and the red bit 306 are written into the frame memory 309 by giving synchronized addresses to the frame memory 309 and the CCDs 2 1 1 and 215 in response to a command from the CPU 3 1 1 . Furthermore, C.P.

Components common to those in the figure are given the same numbers.

In the image scanner 201, 200 is a document holder, and the document 204 on the document glass 201 is held by the lamp 2.

In the control unit, the image scanner unit 201
and controls the printer section 203, has an image memory, holds image signals read by the image scanner section, processes the image, and then sends the image to the printer section.

In the printer section 203, a laser beam driver 216 drives a semiconductor laser based on an image signal sent from the control section 202. The laser beam is transmitted through a polygon mirror 218, an f-theta lens 219. mirror 22
0 and 221 are imaged onto the photosensitive drum 222. The output image formed on the photosensitive drum 222 is developed with toner by a developing device 223 using a known electrophotographic process, and paper is fed from a paper cassette 224 or 225, and a timing chart is taken on a registration roller 226. Afterwards, it is transferred onto the photosensitive drum and transferred to the conveyance system 2.
27, and after the image is fixed in a fixing unit 228, it is output. Figure 3A. FIG. 3B shows a flowchart of the processing procedure of the document proofing device of this embodiment. Figure 3 shows the overall flow. First, in step 5301, an image is read by the image caster 201 and stored in the frame memory 301. In step S302, the calibration symbol written in red is extracted from the data stored in the frame memory, and in step S303, the method of calibration processing is determined. The extraction of calibration symbols in step S302 will be explained in detail below according to FIG. The determined processing is performed in step S304, and after the data in the frame memory has been processed and written, it is outputted by a printer in step S305. FIG. 3B is a flowchart showing in more detail the determination of the calibration process and the calibration process in steps S303 and S304 in FIG. 3A. Step S401. In S404, S41 1...
A predetermined symbol is identified and processing corresponding to that symbol is performed. In this example, first, if the symbol is "L" in the determination in step S401, the process proceeds to step S402, where a character string within the range specified by the symbol "L" is extracted, and step S
In step 403, conversion to an italic character corresponding to the symbol "L" is performed. If the symbol is "X" as determined in step S404, the process advances to step S405, where it is determined whether the character string in the document containing the character designated by the symbol "X" is written horizontally or vertically. This determination will be explained in detail below according to FIG. In step S406, the process branches depending on whether the text is horizontal or vertical. If the text is horizontal, the process proceeds to step S407, where a horizontal character string containing the symbol "X" is extracted; if the text is vertical, the process proceeds to step 3408, where the symbol "X" is extracted. ” is extracted. Next, in step S409, the character indicated by the symbol "X" is deleted, and in step S4
10 performs even allocation on the remaining strings. If the symbol is neither “L” nor “X”, step S4
A determination is made as to whether the symbol is a predetermined symbol 11 or later, and a proofreading process corresponding to the symbol is performed, for example in step S412. The flow of the calibration process will be specifically shown below according to Figure 4. Document to be read> 601 is a document to be read, which is the same as 204 in FIG. Here, proofreading symbols 610 and 611 are written in red letters like normal proofreading symbols and are extracted from the manuscript.
Proofreading symbols 605 and 606 in the original 602 are obtained. In this embodiment, the proofing symbol 610 is a symbol that converts a character string surrounded by symbols into italic type, and the proofing symbol 611 is a conversion that erases the character in which the symbol is written and evenly fills adjacent character strings. Suppose that the symbol is

Calibration symbol extraction> Figure 5 shows the principle of extraction of calibration symbols in the red extraction circuit 306. 501 is the character string rABCl drawn in black, and 502
is a proof symbol drawn in red. At this time, for example, the signal level of CCD 2 1 1 on a certain main operation line x-x' is shown at 503, and the signal level of COD 2 1 5 is shown at 504. Further, the signal 505 is obtained by subtracting the signal level 504 from the signal level 503. Here, C
CD2 1 1 is the ND image signal, and CCD2
15 is a red filter signal, by binarizing the difference signal 505 at a certain slice level T, only the red portion can be extracted as shown at 506. Determining the orientation of character strings in a manuscript> In the case of proofreading symbol 611, the orientation of the manuscript is determined because the processing method differs depending on whether the manuscript is written vertically or horizontally. Figure 7 shows a diagram illustrating an example of document orientation determination. That is,
In an area 701 in the vicinity of the calibration symbol 611, the average value taken in the X direction is displayed on the Y axis, and 702 shows the average value taken in the Y direction on the X axis. What is displayed is shown in 703. In the example of FIG. 7, since the manuscript is written horizontally, the text 702 is clearly divided into a background part (high level) and a non-texture part. Therefore, in 702, if the signal is cut off at an appropriate slice level T, the background portion can be detected as shown in the figure. On the other hand, in a signal in a direction perpendicular to that, such as 703, the background cannot be extracted well. In other words, by comparing 702 and 703 on the condition that "the period equal to or greater than the threshold value T continues for a certain period of time", it is possible to distinguish whether the original is written vertically or horizontally. ．． Character string extraction/proofreading process> Furthermore, in FIG. 4, after determining whether the character string is written vertically or horizontally in the vicinity of the proofreading symbol 611,
A character 608 to be processed and an area 609 affected by the processing are cut out and processed to obtain an output 604.

A detailed explanation of the processing will be omitted, but since the image has already been stored in the frame memory, CPU3 1 1
It is easily converted by

Note that in this embodiment, the character string is black and the proof symbol is red, making it a two-color reading device, but the invention is not limited to this. In other words, it is sufficient to be able to detect the difference in the spectral sensitivity distribution between the character string and the calibration symbol. For example, in a full-color reading and output device, it is also possible to proofread a document using proof symbols of a specific color that is not present in the original. Further, in the present embodiment, a conversion is described in which unnecessary characters and neighboring character strings are evenly compressed, but the present invention is not limited to this.

As explained above, this is a device that stores handwritten proofreading symbols, performs automatic proofreading based on the recognized proofreading symbols, determines the direction of the character string near the proofreading marks, and performs appropriate proofreading. It automates calibration. [Effects of the Invention] According to the present invention, it is possible to provide a document proofreading device that can perform appropriate proofreading processing corresponding to proofreading symbols in a short time.
