Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for creating a document in which information that is read by an optical reading section and converted into an electrical signal is formed on a sheet of paper.

For example, in facsimile machines, a band compression method is used as a signal transmission method to reduce the time required to transmit a document.

This is a method that skips important parts of the manuscript (margins, line spacing, artificially masked white parts, etc.) and transmits only the necessary parts, which cleverly reduces the amount of transmitted data. Ru. In other words, even for originals of the same size, the smaller the amount of required information, the shorter the time required to occupy the same line, and the efficiency of continuous use can be improved, allowing a large number of originals to be sent per unit time. However, normally, even when transmitting only a small portion of a single document, troublesome operations such as masking are not performed.
Generally, the entire manuscript is transmitted. Therefore, conventionally, shortening the transmission time has relied solely on skipping the margins and line spacing of the manuscript, and active shortening methods such as maskinog are currently difficult to implement because the work is time-consuming. . This invention has been made in view of the above points, and uses an extremely simple method of simply superimposing the dropout colors in the optical discussion section to make only the necessary portions of the original a non-dropout color in the optical discussion section. The purpose of the present invention is to provide a manuscript preparation method that enables discussion, significantly shortens transmission time, and improves operational efficiency.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 shows an example of the color sensitivity characteristics of the optical transmission section of a facsimile machine (such as a solid-state scanning device). has high color sensitivity, but has low color sensitivity for colors from blue to violet (colors with short wavelengths). In other words, letters, figures, etc. written in red colors are detected as electrical signals at a level close to white, and letters, figures, etc. written in purple colors are detected as electrical signals at a level close to black. It looks like it will be done. By the way, facsimile machines generally change signals close to the white level to white and signals close to the black level to black, at a certain level, in order to prevent dirt on the original, background color, etc. from appearing on the received image. There are many things that I try to do. For this reason, even if the manuscript is multicolored and written at the same density, colors ranging from mild to red will not be read and will be read as a white signal (i.e., the ground color), and colors from blue to purple will be read as a black signal. It will be done. In other words, in addition to black, parts colored in colors ranging from blue to purple are also captured and transmitted. Generally, the color that is processed as a white level in the optical reading section is called a dropout color in the optical reading section, and the color that is processed as a black level is called a non-dropout color in the optical reading section. There is. By the way, a non-dropout color can be obtained by color compositing the two different dropout colors. For example, if red is used as the first dropout color and green is used as the second dropout color, and the two are combined, a color close to black will be obtained, and a non-dropout color can be obtained. FIG. 2 is a diagram showing an embodiment of the present invention, in which 1 is a manuscript paper, A, B, C, . . . are manuscript papers 1.
These are the characters written on the .

The letters A, B, C, . . . are written in a first dropout color, for example, a red water-based sign. In such a document, if you want to transmit only the characters C, D, F, and G, fill in the characters C, D, F, and G with a second dropout color, for example, green, as shown in Figure 2b. . In FIG. 2b, the shaded area 2 is the area filled in with the second dropout color. This results in
Only the parts of the letters C, D, F, and G are combined with red and green and change to a color close to black. Therefore, only the letters C, D, F, and G are in non-dropout color, so if you transmit this document by facsimile, only the letters C, D, F, and G will be read, and the other parts will be in dropout color. Since the image is in color, there are no differences, and a received image as shown in FIG. 2c is obtained on the receiving side. In this way, in this invention, only the necessary information part of the original is converted into a color that can be detected by the optical processing section, that is, a non-dropout color, thereby reducing the ratio of the necessary information amount to the total information amount and reducing the transmission time. We are planning to shorten the

In other words, even if the document size is the same, the smaller the amount of information required, the shorter the line occupation time, making it possible to send multiple documents, and therefore the transmission time per document can be significantly reduced. be. As explained above, according to the present invention, characters and the like are written on a document using the dropout color of the optical reading section, and only the part that is to be transmitted, that is, the part that is to be read by the optical reading section, is filled in with another dropout color. By using drop-out coloring, transmission time can be shortened without performing complicated masking operations, and operational efficiency can be greatly improved. Especially for documents using fixed formats, it is possible to reduce the expected This is very effective when a large number of items are entered and some of them are selected and transmitted.
