Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to an image communication apparatus and an image communication method such as a facsimile machine capable of communicating information taken by a digital camera.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus capable of printing information taken by a digital camera has been proposed. Further, in some facsimile machines, when transmitting information photographed by a digital camera, this information is once restored to RGB, and the ITU-T recommendation T.264. Four
2, T. Based on 81, it is re-encoded, converted into color facsimile information, and transmitted by facsimile.

[0003]

However, in the above conventional example, the information taken by the digital camera has a resolution of 200.
Since it is converted into the color facsimile information of dpi, and the RGB is once restored, the image quality is deteriorated. Therefore, it is impossible for the receiver side to record with the high image quality as taken by the transmitter. There's a problem.

Information captured by a digital camera is
Although the number of images and the amount of the images vary depending on the user's shooting conditions, shot images, etc., there is a problem that the number of images and the amount of these images cannot be stored and transmitted.

The above problem is a problem that occurs in image communication devices other than facsimile devices.

According to the present invention, it is possible to record on the receiver side while maintaining the high image quality as taken by the transmitter, and
It is an object of the present invention to provide an image communication device and an image communication method capable of surely communicating by designating the number of images and capacity of information taken by a digital camera.

[0007]

According to the present invention, in an image communication apparatus capable of communicating color information, a receiver notifies a transmitter of the presence or absence of a function of receiving information taken by a digital camera, and the digital camera From the receiver, notify the transmitter of the number of pixels that can receive the captured information, specify the transmission of the information captured by the digital camera from the transmitter to the receiver,
When the transmitter specifies the number of pixels to transmit the information captured by the digital camera to the receiver, and the transmitter specifies the transmission of the information captured by the digital camera, the digital camera specified by the transmitter captures the information. The image communication device changes the recording position based on the number of pixels for transmitting the information.
