FIG. 4 is a flowchart showing the resolution conversion operation and the transmission operation on the transmitting station side of the present embodiment. FIG.
Is a flowchart showing a receiving operation on the receiving station side corresponding to the operation on the transmitting station side. First, with reference to FIG. 4, a description will be given of the transmission condition conversion operation and the transmission operation on the transmitting station side. In step S1, transmission parameters are set. Here, polling communication and designation of transmission parameters such as a halftone original are performed. In step S2, a destination is set. In this setting, a telephone number of a destination facsimile (hereinafter, referred to as a facsimile number) is set by a key operation of the operation display unit 2. This fax
The number may be set by operating a key each time.
The AX number may be read out by presetting a speed dial or the like by pressing a speed key. In step S3, transmission start is instructed by operating a start key (not shown) on the operation display unit 2. In step S4, the scanner 4 reads an original upon receiving an instruction to start transmission. In step S5, for example, the paper size A
The image information read under the transmission conditions of 0, resolution 400 × 400 ppi, and monochrome color is stored in the storage device 5. In step S6, the communication information storage unit 6
Stores the transmission condition. For example, paper size A
0, a resolution of 400 × 400 ppi, and transmission conditions of two colors are stored. The configuration of the communication information storage unit 6 is shown in FIG.
As shown in (1), one area on the memory stores compression conditions of image information such as resolution at the time of storage and transmission, and the other one stores whether the conditions at the time of storage are converted during transmission. Stores information indicating whether or not this is the case. In step S7, the destination FAX number set in step S2 is called. In step S8, a notification of the reception capability declaration of the called receiving station is received by, for example, an NSF command. In this embodiment, the reception capability declaration declares, for example, that the paper size is A4, the resolution is 200 × 200 ppi, and the color is monochrome. In step S9, the main controller 1
Then, it is determined whether the automatic conversion of the image information is necessary by comparing the transmission condition and the reception capability declaration. If at least one of the paper size, resolution, and color / black and white information of the document declared in the reception capability declaration does not match the transmission condition, it is necessary to convert the transmission condition. Proceed to step S10. At the same time, the image information is converted. If the declared receiving capability is equal to or higher than the transmission condition, there is no need to convert, so the process proceeds to step S17, where the stored document is transmitted, and the operation ends when transmission is completed. In step S10, it is determined whether the conversion information output from the transmitting station in the main controller 1 is to be transmitted in the form of protocol or image information. When the transmission is selected by the protocol, the process proceeds to step S11. In step S11, the conversion information is transmitted in accordance with, for example, an NSS command of the protocol. In step S12, after transmitting the stored document, the process ends. On the other hand, if it is determined in step S10 that image data is to be transmitted, the process proceeds to step S13.
Then, the stored original is transmitted. In step S14, the paper size, resolution, color / monochrome information and the like of the document stored in the communication information storage unit 6 are formatted into image information. In step S15, after the conversion information is transmitted, the process ends. Next, with reference to FIG. 5, a receiving operation on the receiving station side corresponding to the above-described operation on the transmitting station side will be described. In step S20, upon receiving the call from the transmitting station in step S7, the receiving station transmits a reception capability declaration to the transmitting station. In the present embodiment, the reception capability declaration declares, for example, that the paper size is A4, the resolution is 200 × 200 ppi, and the color is monochrome. In step S21, it is determined whether the conversion information has been received by the protocol. If the conversion information is received by the protocol, step S22
If the image information is received, the process proceeds to step S30. In step S22, the received conversion information is stored in the communication information storage unit 6. In step S23, it is determined whether or not the conversion information stored in the communication information storage unit 6 includes a resolution conversion. If resolution conversion is included, step S2
The process proceeds to step S4, and if not included, proceeds to step S27.
In step S24, it is determined whether an instruction to disconnect the line has been issued. In general, when a resolution-converted received document is printed out, it is expected that the resolution of the received document will be degraded and the image quality will be degraded. Therefore, if it is specified that the line should be disconnected, the line is disconnected and the process proceeds to step S25. When the line disconnection instruction has not been issued, the process proceeds to step S27. In step S25, the line is disconnected, and the communication is terminated. Step S2
In step 6, error information indicating that the automatically converted original has been received but disconnected has been displayed on the operation display unit 2. For example,
A message saying "The machine with the partner machine has been disconnected because of its inability to match" is displayed. If the determination in step S23 is negative, the flow advances to step S27 to receive the image information of the document whose resolution has been converted. In step S28, the reception of the image information ends. In step S29, after the message as shown in FIG. 6 or FIG. 7 is printed out from the printer unit 7, the communication is terminated. FIG. 6 shows an example of the format of image information transmitted from the transmitting station, and FIG. 7 shows an example of the format of image information created on the receiving station side based on the conversion information transmitted from the transmitting station. is there. Further, the contents as shown in FIG. 8 are displayed on the monitor or the like of the operation display unit 2, and the communication is terminated. At this time, an audio device (not shown) may notify the operator that the automatically converted original has been received. The step S
If the determination at 21 is negative, the process proceeds to step S30 to receive the image information, and ends the communication at step S31. As described above, according to the present embodiment, when image information is transmitted after conversion of the paper size and resolution of the original, the transmitting station transmits conversion information indicating this to the receiving station. Notice. On the other hand, the receiving station can recognize this conversion information by displaying or printing it. As a result, if the quality of the received image information is poor, for example, by asking the transmitting station to transmit without converting to a facsimile machine with another high capability, the image information is not degraded. Can be received. Next, the function of the main part of the present invention will be described with reference to the functional block diagram of FIG. In FIG. 1, reference numeral 21 denotes a receiving capability analyzing unit for analyzing the receiving capability of the receiving station, and 22 denotes a transmission condition storing unit for storing the transmitting conditions of the transmitting station. Reference numeral 23 denotes a conversion information creation unit for creating conversion information of the original read from the reading unit 4 based on the transmission conditions and the reception capability. 24 denotes a conversion information output from the conversion information creation unit 23 according to a protocol. Or a transmission method selection unit for selecting which form of image information to transmit. The conversion information is transmitted via the communication control unit 10 and the line control unit 8 in the method selected by the transmission method selection unit 24. Reference numeral 25 denotes a conversion information receiving unit that receives the conversion information via the line control unit 8 and the communication control unit 10, and 26 denotes a conversion information analysis unit that analyzes the received conversion information. An analysis information display unit 27 displays the conversion information analyzed by the conversion information analysis unit 26.
Is a conversion information output unit that outputs the conversion information. For example, the conversion information display unit 27 corresponds to the operation display unit 2 shown in FIG. 2, and the conversion information output unit 28 corresponds to the printer unit 7. As described above, according to the present invention, the transmitting station transmits the conversion information such as the resolution conversion information at the time of storing and transmitting the image information, the conversion information of the paper size of the original, and the color / monochrome conversion information to the receiving station side. By notifying, the receiving station can recognize the conversion information at the time of accumulation. In addition, the conversion information may be displayed and output, and the conversion information may be audibly transmitted to the operator by a sound device (not shown) that generates a sound or a warning sound. In this case, even if the operator is away from the facsimile machine,
It is possible to know as soon as possible that the information has been received after being automatically converted on the transmitting side. As a result, necessary treatment can be performed more quickly. In the present embodiment, the image information is automatically converted. However, even when the operator operates the operation display unit 2 or the like to arbitrarily convert the image information and transmits the image information to the receiving station, The conversion information may be displayed and output as in the present embodiment. [0027] [0028] [0029] [0030] According to the present invention, when the receiving station receives the automatic conversion information in protocol, because automatic communication is disconnected, It is possible to reject the reception of the image information having the deteriorated image quality generated by the automatic conversion. Therefore, unnecessary communication is not required.
