Abstract

PURPOSE:To increase data quantity able to accumulate in a unit memory by having a decoding means and an encoding means between a data reception means and a memory accumulation means and accumulating with the use of the encoding system of high compressibility. CONSTITUTION:Encoded data transmitted from an opponent device are received by a data reception part 11, decoded in a decoding part 12, and stored in a data buffer 13. On the other hand, when the decoded data are stored in the data buffer 13, the data are taken out in an encoding part 14 and encoded by the encoding system of the high compressibility. The data encoded by the encoding part 14 are accumulated in a disk 16 through the control of an accumulation control part 15. Thus, the data quantity able to accumulate in the unit memory can be increased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile apparatus, and more particularly to a facsimile receiver that stores received encoded data in a memory, converting the encoding method and storing data.

2. Description of the Related Art Conventionally, facsimile machines of this type have stored received encoded data in a memory in the received encoded format without performing any conversion.

Problems to be Solved by the Invention In the conventional facsimile receiver described above, data is stored in memory in the received encoding format, so the compression rate (when 1 pixel is 1 bit) is Data received using a method in which the amount of image data/amount of encoded data is generally small has the disadvantage that the amount of original data that can be stored in a memory of the same capacity is small.

The present invention has been made in view of the above-mentioned conventional situation,
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a new facsimile receiver which eliminates the above-mentioned drawbacks inherent in the prior art and makes it possible to increase the amount of data that can be stored in a unit memory.

Means for Solving the Problems In order to achieve the above object, a facsimile receiver according to the present invention includes a data receiving means for receiving encoded data, and a memory storage means for storing the received data in a memory within the device. A facsimile receiver comprising: a means for decoding the encoded data received between the data receiving means and the memory storage means; and a means for encoding the decoded data. , it is characterized by code conversion at the time of reception.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, the data receiving section 11.

It has a protocol based on the CCITT T.30 recommendation, and receives data from a partner device (not shown) through the network, and the decoding unit 12 decodes the received encoded data to generate document data in units of 1 pixel. , the data buffer 13 is a temporary buffer for matching the data transfer rate on the network side and the storage speed on the disk 16 side, the encoding unit 14 encodes document data in units of 1 pixel, and the storage control unit 15 Control is performed to store the encoded data from the encoder 4 on the disk 16, and the disk 16 stores the original data as encoded data.

Next, the operation of the present invention will be explained.

First, the data receiving section 11 receives encoded data sent from a partner device and takes it into the device. The encoding method of the data sent at this time is determined by the data receiving unit 11.
This is determined by the communication protocol between the host device and the other party's device, and depending on the details of the decision, there is a possibility that encoded data using an encoding method with a low compression rate will be sent. The decoding unit 12 decodes the encoded data and stores it in the data buffer 13. On the other hand, the encoding unit 14 decodes the encoded data and stores it in the data buffer 13.
When the decoded data is stored in No. 3, the data is extracted and encoded using an encoding method with a high compression rate. The data encoded by the encoding unit 14 is stored in the storage control unit 1.
5 is stored on the disk 16.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the decoding means and the encoding means are provided between the data receiving means and the memory storage means, and the data is encoded using a different encoding method from the received data encoding method. By storing data, it is possible to perform storage using an encoding method with a high compression rate, and therefore, the effect of increasing the amount of data that can be stored in a unit memory is obtained.
