On the other hand, if the partner receiver does not have the color receiving function of the non-standard size, color communication can be reliably performed at the standard size. SOLUTION: A receiver notifies a transmitter of the presence / absence of a JPEG reception function, notifies a transmitter of a full color reception function,
Notify the presence or absence of the function to receive irregular size color information, specify JPEG transmission from the transmitter to the receiver, specify full color transmission, specify transmission of irregular size color information, and specify irregular size When the transmission of the color information is selected, the control for transmitting the color image signal is changed in accordance with the presence or absence of the non-standard-size color reception function in the other receiver.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus, and more particularly to an image communication apparatus such as a facsimile apparatus capable of performing color facsimile communication and an image communication method.

[0002]

2. Description of the Related Art A conventional facsimile apparatus is an ITU-T.
Designed based on recommendations. In this recommendation, the receiver notifies the transmitter of the presence / absence of the JPEG reception function and the presence / absence of the full-color reception function.
The presence / absence of PEG transmission and the presence / absence of full-color transmission are notified.

Here, when full-color transmission is designated by JPEG encoding, color transmission is performed. In a conventional monochrome facsimile, encoding is performed using MH, MR, MM
R, JBIG, and the like are used. In this case, the size of the image signal is not specified, and in the pre-procedure, the image signal is transmitted as a fixed size such as A4, B4, and A3 in the main scanning direction. The same applies to color facsimile communication.

[0004]

In a monochrome facsimile, original information is frequently transmitted, and there is no problem at all in a fixed size transmission.

[0005] However, in a facsimile machine capable of color communication, there is a need to transmit a photograph size, such as transmitting a photograph of a grandchild to a grandparent. Further, in the transmission of color information, the amount of encoding is large and the color transmission takes time, so that transmitting such information such as photographs as A4 size information is useless. Is wasted.

[0006] This problem occurs in image communication apparatuses other than facsimile apparatuses such as personal computers having an image communication function.

According to the present invention, if the other receiver has a color receiving function of an irregular size, a color smaller than the A4 size which cannot be obtained in color facsimile communication based on the current ITU-T recommendation, for example, a photograph size color Facsimile communication can be performed reliably with other machines, and only the image signal of the color size that the user wants to send can be sent.On the other hand, the other party's receiver has an irregular size color reception function. If not, an object of the present invention is to provide an image communication apparatus and an image communication method capable of reliably performing color communication in a fixed size.

[0008]

SUMMARY OF THE INVENTION According to the present invention, in an image communication apparatus capable of communicating color information, a receiver notifies a transmitter of the presence / absence of a JPEG reception function, and notifies a transmitter of the presence / absence of a full color reception function. Means for notifying the presence or absence of a function for receiving irregular size color information, means for specifying JPEG transmission from the transmitter to the receiver, means for specifying full color transmission, and irregular size color information When the transmission of non-standard-size color information is selected and the transmission of the non-standard-size color information is selected, the control for transmitting the color image signal is changed according to the presence / absence of the non-standard-size color reception function in the partner receiver. An image communication apparatus having a control changing unit that performs the control.

According to the second embodiment, in the first embodiment, if the other party's receiver has a non-standard size color receiving function, the non-standard size is designated by JPEG encoding information. When the non-standard-size information transmission is performed and the receiver does not have the function of receiving the non-standard-size color, the transmission can be performed as the standard-size.

As a result, if the other receiver has a color receiving function of an irregular size, the current ITU-
Color facsimile communication smaller than A4 size, which cannot be performed in color facsimile communication based on the T recommendation, for example, photo facsimile color facsimile communication can be reliably performed with other machines, and images of color sizes desired by the user to be transmitted can be transmitted. Only signals can be transmitted, and if the other receiver does not have a non-standard size color receiving function, color communication in a standard size can be reliably performed.

Further, in the above-described embodiment, a means for automatically recognizing the document size is provided, and if the above-mentioned control is executed based on the automatically recognized document size, the user transmits color information of an irregular size. At this time, for example, a transmission selection operation for, for example, a photograph size is not required, and labor for transmitting color information of a non-standard size can be greatly reduced, which makes the user very easy to use.

Further, in the above embodiment, when transmission of non-standard size color information is selected and the receiver of the other party does not have a function of receiving non-standard size color information, one piece of non-standard size information is fixed. If it has a selection means to select whether to transmit as a size, or to transmit a plurality of information of non-standard size collectively as a standard size, transmission of color information of non-standard size is selected, and the other receiver is If there is no function to receive color information of non-standard size, register the selection information of whether to send information of one non-standard size as standard size or collectively send information of multiple non-standard sizes as standard size. It is possible to have a means to do so.

Thus, when transmission of non-standard-size color information is selected, if the other receiver does not have the function of receiving non-standard-size color information, the color information is set as the standard size based on the method registered by the user. Can be transmitted, and an original of an irregular size that meets user needs can be transmitted in color.
