2. Description of the Related Art Conventionally, most facsimile apparatuses transmit monochrome facsimile information. In a transmission control procedure of a facsimile apparatus for transmitting black-and-white facsimile information, for example, using the 42 bits of the FIF of the DIS signal, 300 d in both the main scanning direction and the sub-scanning direction.
pi reception / recording function can be declared, and DC
By using the 42 bits of the S-signal FIF, transmission of 300 dpi can be designated in both the main scanning direction and the sub-scanning direction.

[0003]

In recent years, the need for transmission of color information has been increasing.
T issued a recommendation on the transmission of color information. Specifically, the reception capability of the JPEG encoding using the 68 bits of the FIF of the DIS signal is enhanced by the FI signal of the DIS signal.
The full-color mode receiving capability can be declared using the 69 bits of F. If these bits are both “1”, both 68 and 69 bits of FIF are 1
By transmitting the DCS signal, color facsimile communication can be designated.

[0004] Thereafter, in June 1998, a recommendation was made that a high resolution (97 bits of FIF) for color could be defined.

When performing color transmission on i, a communication error occurs,
This communication error indicates that the other party does not have a color reception function at 300 dpi. As a result, when color transmission is performed next to the same destination at 300 dpi, a communication error similarly occurs, and color transmission at 300 dpi cannot be normally terminated. And
It is necessary to perform retransmission by changing the transmission mode, and it takes time to change the transmission mode.

The determined transmission mode is registered in the RAM 18, and the RAM 18
When the color transmission mode with the predetermined resolution is selected for the destination registered in the, the transmission mode registered in association with the destination is executed, so it is unknown whether the color reception function at the predetermined resolution is available. It is possible to execute an appropriate transmission mode for an appropriate destination.

Also, the transmission mode determined to be executable for a destination that cannot execute the color transmission mode at the predetermined resolution is a monochrome transmission mode at the predetermined resolution and a color transmission mode at a resolution lower than the predetermined resolution. It is assumed that there is a color transmission mode at a predetermined resolution, and one of a transmission mode in a monochrome mode at a predetermined resolution and a transmission mode in a color mode at a resolution lower than the predetermined resolution is registered in association with a destination that is not executable. Accordingly, it is possible to set according to the user's request whether to give priority to color transmission to a destination that cannot execute the color transmission mode at a predetermined resolution or to give priority to resolution for monochrome transmission.

Further, when retransmitting to a destination that cannot execute the color transmission mode at a predetermined resolution,
After the registration of the transmission mode executable by the other party is completed, the retransmission is performed in the registered transmission mode, so that the retransmission can be performed in an appropriate mode without any trouble for the user.

In this embodiment, the predetermined resolution is 3
The case of color transmission at 00 dpi has been described.
It goes without saying that a case of color transmission at 0 dpi can be similarly handled.

An appropriate transmission mode can be executed for a destination whose presence or absence of a color reception function at a predetermined resolution is unknown.

The plurality of transmission modes include a monochrome transmission mode for transmitting monochrome facsimile information at the same resolution as a predetermined resolution, and a color transmission mode for transmitting color facsimile information at a resolution lower than the predetermined resolution. If the transmission mode determined to be executable for a destination that cannot execute the color transmission mode is a monochrome transmission mode at a predetermined resolution and a color transmission mode at a resolution lower than the predetermined resolution, the color transmission mode at the predetermined resolution By registering one of a transmission mode in a monochrome mode at a predetermined resolution and a transmission mode in a color mode at a resolution lower than the predetermined resolution in association with a destination in which the transmission mode is not executable, a color at a predetermined resolution is registered. Priority is given to color transmission for destinations that cannot execute transmission mode. Luke, is a black and white transmission it is possible to set according to whether to prioritize the resolution to user needs.

Further, when retransmitting to a destination that cannot execute the color transmission mode at a predetermined resolution,
By performing retransmission in the transmission mode registered in the registration means immediately after the destination registers the executable transmission mode, the retransmission can be performed in an appropriate mode without any trouble for the user. it can.

Further, the predetermined resolution is 300 dpi, and the resolution lower than the predetermined resolution may be 200 dpi in the main scanning direction and the sub-scanning direction.

Claims (8)

[Claims] In a facsimile apparatus capable of executing a plurality of transmission modes including a color transmission mode for transmitting color facsimile information at a predetermined resolution, when a color transmission mode at the predetermined resolution is selected as a transmission mode for the destination. Determining means for determining whether or not the color transmission mode at the predetermined resolution is executable for the destination; and determining whether the color transmission mode at the predetermined resolution is not executable for the destination. Determination means for determining a transmission mode that can be executed with respect to the destination, and registration means for registering the transmission mode determined to be executable with respect to the destination in association with the destination, and registering in the registration means When the color transmission mode at the predetermined resolution is selected for the destination, the transmission mode registered in association with the destination is selected. A facsimile machine for executing a fax mode. 2. The plurality of transmission modes include a monochrome transmission mode for transmitting monochrome facsimile information at the same resolution as the predetermined resolution, and a color transmission mode for transmitting color facsimile information at a resolution lower than the predetermined resolution. The transmission mode determined to be executable for a destination that cannot execute the color transmission mode at the predetermined resolution by the determination unit is a monochrome transmission mode at the predetermined resolution and a color transmission mode at a resolution lower than the predetermined resolution. When in the transmission mode, the registration unit associates with a destination in which the color transmission mode at the predetermined resolution is not executable, and transmits in the monochrome mode at the predetermined resolution and the color at a resolution lower than the predetermined resolution. Claiming one of the transmission modes according to the transmission mode Item 1. A facsimile apparatus according to Item 1. 3. When performing retransmission to a destination that cannot execute the color transmission mode at the predetermined resolution, immediately after registering a transmission mode executable by the destination by the registration unit, the retransmission is performed. 3. The facsimile apparatus according to claim 1, wherein the step (c) is executed in a transmission mode registered in the registration unit. 4. The predetermined resolution is 300 dpi,
