Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication apparatus, and more particularly to a communication apparatus (facsimile apparatus) capable of transmitting color information.
[0002]
[Prior art]
The conventional facsimile apparatus capable of monochrome facsimile communication has means for registering whether or not to execute the error correction mode, and if the communication in the error correction mode is not selected, the transmitter is set at the time of reception. On the other hand, the pre-procedure is executed by changing only the information without the reception function in the error correction mode by the DIS signal, and at the time of transmission, only the information not specifying the error correction mode is changed by the DCS signal and the pre-procedure is executed. .
[0003]
[Problems to be solved by the invention]
However, ECM communication is indispensable in color facsimile communication when color facsimile apparatuses appear. For example, when a DIS signal in which only the error correction mode is deleted is transmitted at the time of reception, when the transmitter receives the DIS signal, There was a major drawback that correct operation was impossible.
[0004]
[Means for Solving the Problems]
According to a first aspect of the present invention, in a communicable communication device color information, to the receiver, designated whether to transmit based on the JPEG encoding, specify whether or not to color transmission, error correction A means for specifying whether to perform transmission in a mode, a means for selecting whether to perform error collection transmission, a means for selecting color transmission , and color transmission is selected. also, it has become possible that do not perform regardless of color sent to the selection status of the color transmission based on the fact that it has been selected that do not perform error correction transmission.
[0005]
According to the second aspect of the present invention, when color transmission is selected in the first aspect of the present invention, color transmission cannot be executed if the other receiver does not have a color reception function and a JPEG reception function. .
[0006]
As a result, error collection transmission is not executed, but when selected, color transmission can also be prevented, and there is no problem in the protocol, and facsimile transmission without executing error correction mode reliably. Became possible and became very easy to use.
[0007]
According to the third aspect of the present invention, in a communication apparatus capable of communicating color information, the transmitter is provided with a presence / absence of a reception function based on JPEG encoding, a presence / absence of a color reception function, and a presence / absence of a reception function in an error correction mode. hand stage to be notified, and means for selecting whether to perform an error correction receiver, based in particular to not perform the error correction reception is selected, no reception function based on JPEG encoding, It is now possible to notify that there is no color reception function and no reception function in error collection mode.
[0008]
As a result, error correction reception is not executed, but when it is selected, color reception is also not possible, and there are no problems with the protocol, and facsimile reception without executing error correction mode reliably. Became possible and became very easy to use.
[0009]
According to a fourth aspect of the present invention, in a communicable communication device color information, to the transmitter when operating as a receiver, the presence or absence of the reception function based on JPEG encoding, the presence or absence of color receiving function, an error correction mode Means for notifying the presence or absence of a reception function at the time, specifying whether to perform transmission based on JPEG encoding to the receiver when operating as a transmitter, specifying whether to perform color transmission, error correction mode A means for specifying whether or not to perform transmission, a means for selecting whether or not to execute error correction communication, a means for selecting color transmission,
When operating as a transmitter, even if color transmission is selected, color transmission is not performed regardless of the color transmission selection status based on the fact that error correction communication is not performed , In addition, the remote receiver has a control means that does not execute color transmission based on the absence of the color reception function and the JPEG reception function, and it is selected not to execute error correction communication when operating as a receiver. with particular basis are, the notification means, without receiving function based on JPEG encoding, no color receiving function, has become possible to notify without receiving function of the error correction mode to the transmitter.
[0010]
As a result, error correction communication is not executed, but when it is selected, color communication is also not executed, and there is no problem in the protocol, and facsimile communication without executing error correction mode reliably. Became possible and became very easy to use.
