Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus having a function of reading a color original and a function of storing image data. 2. Description of the Related Art Conventionally, in normal facsimile communication, all received image data is printed immediately.
Further, a facsimile apparatus having an image data storage unit has a function of confidential communication in which all received documents are once stored in the image data storage unit and printed only after performing a predetermined operation (such as inputting a password). . [0003] However, in the ordinary facsimile communication of the above-mentioned conventional example, all the received documents are immediately printed, so that the received document can be sent to a person other than the sender's request. However, there was a drawback in that it could be seen. Further, in confidential communication for compensating for the above-mentioned drawbacks, when a facsimile machine on the receiving side is used by a plurality of persons, it is not known to whom the received document stored in the image data storage unit belongs. However, there is a disadvantage that the sender needs to notify the receiver of the fact by telephone or the like. SUMMARY OF THE INVENTION It is an object of the present invention to provide a facsimile apparatus capable of performing image communication in which a receiver can easily recognize a recipient's reception while securing necessary confidentiality. According to the present invention, there is provided a method for creating a transmission original.

can do. FIG. 1 is a block diagram showing the configuration of a first embodiment of the present invention. The color scanner 1 is an image reading device controlled by the CPU 2 through a control signal line 14a, can read a transmission original in color, and outputs R, G, and B color signals to one pixel by a signal line. 8a, 8b, 8
c, and the R, G, and B color signals are taken into the CPU 2. The CPU 2 is a central processing unit that controls other units, performs arithmetic processing on image data, and the like. The operation panel 3 has operation keys and a display for operating the present apparatus.
Is controlled. The image data storage section 4 is a memory for storing image data and the like, and writing and reading are controlled by the CPU 2 through a control signal line 12. The modem 5 modulates image data and demodulates a received signal. The modem 5 exchanges data with the CPU 2 via a data signal line 9 and is controlled by a control signal line 14b. The NCU 6 is a communication control device for connecting to a public telephone line network,
And the CPU is connected by the control signal line 14c.
2 is controlled. The printer 7 is for printing a received image, and is controlled by the CPU 2 through a signal line 13. Next, FIGS. 2 and 3 are flowcharts showing the operation in the present embodiment. In the present embodiment, it is assumed that the setting of “an image written in red is a confidential part” is made in advance, and a description will be given along this flowchart. S1 shows a state at the time of start,
The sender sets a document in which the confidential portion is written in red in the color scanner 1, inputs the telephone number of the transmission destination on the operation panel 3, and presses the start button. Next, in S2, the original is read. This is a control signal from CPU 2 (signal line 14a).
Accordingly, the color scanner 1 starts reading the document. The R, G, and B signals output from the color scanner 1 are captured by the CPU 2. Next, in S3, the color of the pixel is determined based on the R, G, and B signals captured in S2, and if the color of the pixel is white, the process proceeds to S4 and is set in advance. If the designated color (red in this embodiment) of the confidential portion is set, the process proceeds to S5, and if the color is other than the designated color, the process proceeds to S6. In S4, S5, and S6, the image data is converted to black and white, and two types of transmission image data, a public part and a confidential part, are created. First, in the case of S4, both the public part image data and the confidential part image data are created as white pixels. In the case of S5, the data is created as white pixels for the public part image data and as black pixels for the confidential part image data. Further, in the case of S6, data is created as black pixels for public part image data and white pixels for confidential part image data. Next, the two types of image data of the public part and the confidential part created in S4, S5 or S6 are stored in the image data storage unit 4 in S7. Then, in S8, it is determined whether or not reading of the original is completed. If not completed, the flow returns to S2. If the reading is completed, the process proceeds to S9. In step S9, facsimile transmission is started.
After dialing the telephone number set in step 1 and receiving the call, a normal pre-facsimile procedure is performed. Next, in step S10, the image data of the public portion of the two types of image data of the public portion and the confidential portion created in steps S2 to S8 and stored in the image data storage section 4 is transmitted. This transmission is a normal facsimile communication, and is printed immediately on the receiver side. After the transmission of the public partial image data is completed in S10, the transmitter sends a signal indicating the end of the page to the receiver in S11.
Declare the next page. After that, it declares that the communication mode is to be changed, and instructs the receiver to perform confidential reception (reception of storing the received document in the image storage unit without immediately printing) by using an optional function in the communication mode. . Thereafter, in S12, the confidential image data stored in the image data storage unit 4 is transmitted. This image is not immediately printed on the receiver side, but is stored in the image data storage unit 4. When the transmission of all the image data is completed in this way, the facsimile communication is terminated by a post-procedure of the facsimile communication in S13, and the telephone line is released. Further, in S15, the image data storage unit 4
Deletes the transmitted image data stored in, and ends the processing. According to the method described above, the original 15 as shown in FIG. 4A is created and transmitted, so that only the public portion 16 is formed on the receiver side as shown in FIG. 4B. Immediate printing is performed, and the confidential portion is stored in the image storage unit 4.
When the recipient performs an operation such as inputting a predetermined password, a confidential document 17 as shown in FIG. 4C is printed. Next, a second embodiment of the present invention will be described. The configuration of the device in the second embodiment is the same as that of the first embodiment.
It is assumed that this is the same as the embodiment (FIG. 1). In the first embodiment, the confidential portion is created in the designated color (red), and the public portion and the confidential portion are distinguished from each other. An area is designated by surrounding the confidential part using a line marker or the like, and the public part and the confidential part are distinguished. FIG. 5 is a flow chart showing the operation of the present embodiment, which will be described below. S15 indicates a state at the time of start, and S16 indicates reading of a document. These are the same as S1 and S2 in the first embodiment (FIG. 2). Next, the color image data captured by the CPU 2 in S16 is stored in the image data storage unit 4 as color data in S17. In S18, it is determined whether or not the reading is completed. If the reading is not completed, the flow returns to S16 and the reading is repeated. When the reading is completed, the process proceeds to S19. In step S19, the color image data (hereinafter, referred to as basic image data) stored in the image data storage unit 4 is searched for data of a color designated in advance, and an image data area (hereinafter, referred to as a basic image data) surrounded by the data is searched. , Designated image data area). Next, in S20, the image data in the designated image data area obtained in S19 is copied as confidential partial image data to a confidential partial storage newly provided in the image storage 4. At this time, since the image data is color data, the image data is converted to black and white to be confidential partial image data. In S21, all the image data in the designated image data area of the basic image data is converted into white data. Thereafter, the color data is converted to black and white to obtain public partial image data. As described above, the public partial image data and the confidential partial image data are created in the image storage unit 4 as in the first embodiment. Thereafter, as in the first embodiment, the process proceeds to S9 in FIG. 2, facsimile transmission is performed, and the process ends in S14 in FIG. According to the present invention , the public portion can be printed immediately.
