SOLUTION: In the case of a transmission instruction, the lighting state of a color LED is controlled depending on whether or not a color key is depressed so as to display which of the transmission in the color mode or in the black/white mode the facsimile terminal instructs (S103-S106), the facsimile terminal decides which of the transmission in the color mode or in the black/ white mode depending on the transmission instruction and the presence of declaration of the color reception capability from an opposite terminal, and the LCD displays a message denoting it during the transmission state. The facsimile terminal decides the mode during reception depending on whether an opposite terminal instructs the transmission in the color mode or in the black/white mode and the LCD displays a message denoting it (S121, S122).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color facsimile apparatus, and more particularly to a display in a color mode and a monochrome mode.

[0002]

2. Description of the Related Art In recent years, color facsimile apparatuses capable of transmitting and receiving not only black-and-white binary images but also color images have been provided. In particular, regarding transmission and reception of color images, a communication procedure conforming to the ITU-T recommendation, which specifies that JPEG is used as a compression method, is used.

In this type of apparatus, at the time of transmission, an operator instructs whether to transmit in black and white or in color, and reads and transmits the original in black and white or color accordingly. In the reception, a monochrome image or a color image sent from the transmission side is printed / recorded. At the time of transmission, it is common to provide a lamp or the like for displaying whether the mode is the color mode or the monochrome mode in accordance with an instruction from the operator.

[0004] On the other hand, if the other party cannot receive color data despite instructing color transmission, the line is temporarily disconnected and the call is re-transmitted in the black and white mode and transmitted again, or the color image is converted to black and white binary. It is also conceivable to perform a process of transmitting the data while converting the data into the data.

[0005]

However, the conventional color facsimile apparatus does not display the image mode to be actually transmitted, so that when the color mode is instructed, it is determined whether the image is actually transmitted in the color mode. However, there is a problem that the operator cannot accurately grasp this.

In order to solve this problem, a method of displaying a mode of a communication image during communication by using a mode display unit which is displayed when the user designates monochrome or color is considered.

However, on the other hand, a facsimile apparatus has conventionally been provided with an image memory for storing image data, and using this, an original is read for the next transmission during transmission or reception, and is temporarily stored in the image memory. And a so-called transmission reservation function that starts the next transmission after the line is released.
That is, since the transmission or reception and the reading operation proceed simultaneously and in parallel, the above-described method has a problem that the operator cannot accurately check the state of each operation.

The present invention has been made in such a situation, and in any case of a transmission instruction, a transmission, and a reception, it is possible to determine whether the image mode is a color mode or a monochrome mode. It is an object of the present invention to provide a facsimile apparatus, a mode display method thereof, and a storage medium which can be accurately confirmed.
