Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image communication apparatus such as a facsimile apparatus capable of color transmission.

[0002]

2. Description of the Related Art A conventional facsimile apparatus mainly transmits black and white binary documents.

However, recently, with the spread of personal computers and color printers, color document information has been increasing. Here, the T.T. 4, T. 30, T.I.
42, T.R. According to the recommendation No. 81, color transmission has been recommended, but a facsimile apparatus based on this recommendation has only begun to appear.

[0004]

Here, it is conceivable to transmit a mixed original containing color original information and a black-and-white binary original.
At present, the mode returns to phase B and a mode change is performed each time the monochrome original and the color original are switched.

[0005] However, if the above switching is performed frequently, there is a problem that the communication time becomes longer.

A color facsimile machine currently shipped to the world is intended for home use, has a small amount of memory, and is expected to be unreceivable if switching between a color original and a black-and-white original is frequently performed. There is a problem.

According to the present invention, when a color original and a black-and-white original are mixed in a transmission original, the page number of the original information is set in the page order, and the black-and-white original and the color original can be transmitted together. It is an object of the present invention to provide an image communication apparatus in which the mode change due to the difference between the originals is performed only once, the communication time is reduced, and the possibility of a communication error is reduced.

If a part of the information is color information, the transmission order of the document information is changed and transmitted when a predetermined condition is satisfied.

The above predetermined condition is a condition that switching between a continuous color original and a continuous black and white binary original occurs twice or more.

Here, the page number of the document information is added as a reading order to a part of the image information and transmitted. If a part of the document information is color information and a predetermined condition is satisfied, the black and white binary document is transmitted collectively in the page order first, and then the color document is transmitted collectively in the page order. The originals are sent together in the page order, and then the black and white binary documents are sent together in the page order.

In the above case, it is possible to select whether the black and white binary information is transmitted first collectively or the color information is transmitted first collectively, and a part of the document information is color information. In addition, when the predetermined condition is satisfied, information indicating that the black and white binary document and the color document are separately transmitted is transmitted from the transmitter to the receiver.

The above control program is stored in the ROM 24.

According to the above embodiment, when a color original and a black-and-white original are mixed in the original to be transmitted, the page number of the original information is set in the page order, and the black-and-white original and the color original are transmitted together. Only one mode change due to the change between the black and white original and the color original is required, the communication time is reduced, and the possibility of a communication error is reduced.

In the above case, it is easy for the user to use because the user can select whether to transmit the color information at once or the black and white binary information at once.

In the above embodiment, first, the black and white 2
If the value information is sent together, the call is released once, then the call connection is made again to the same destination, the remaining color information is sent together, while if the color information is sent first, once Since the call is released, the call connection is made again to the same destination, and the remaining black-and-white binary information is transmitted together, the mode change accompanying the change between the black-and-white binary information and the color information is executed. Even if the receiver has a communication error, such information can be transmitted.

In the above case, each call destination corresponds to
Means are provided for counting the number of consecutive communication errors during the mode change of color communication and black-and-white binary communication on the way. On the other hand, if the black and white binary information is transmitted together at first, the call is released once, then the call connection is made again to the same destination, and the remaining color information is transmitted together, while the color information is transmitted first. Are transmitted together, the call is released once, and then a call connection is made to the same destination again, and the remaining black and white binary information is transmitted together.
Therefore, during communication, a mode change between color communication and black-and-white binary communication is executed.
Calls can be sent separately.

Although the above embodiment is a facsimile apparatus, the above embodiment may be applied to an image communication apparatus other than a facsimile apparatus such as a personal computer having an image communication function.
