It is about.

제1도는 종래 팩시밀리의 화상처리장치 구성도로서, 이에 도시된 바와같이 제어메모리부(11)에 저장된 프로그램에 따라 시스템 전체를 제어하는 중앙처리장치(10)와, 시스템버스(BUS10)를 통헤 수신된 부호화된 화상테이타를 저장하는 부호 메모리부(12)와, 상기 시스템버스(BUS10)와 로우컬버스(BUS11)를 연결하여 데이타를 인터페이스하는 버스접속부(13)와, 원고를 독취하는 독취제어부(14)와, 상기 독취제어부(14)에서 독취한 화상데이타를 이미지버스(BUS12)를 통해 저장하는 이미지 메모리부(15) 및 기록하는 기록제어부(16)와, 상기 로우컬버스(BUS11)와 이미지버스(BUS12)에 연결되어 화상데이타를 부호화하거나 복원하는 부호/복호부(17)로 구성된다.1 is a configuration diagram of an image processing apparatus of a conventional facsimile, as shown in FIG. 1, through a central processing unit 10 for controlling the entire system according to a program stored in the control memory unit 11 and a system bus BUS 10 . A code memory unit 12 storing the received encoded image data, a bus connection unit 13 connecting the system bus BUS 10 and the local bus BUS 11 to interface data, and reading the original A read control unit 14, an image memory unit 15 for storing the image data read by the read control unit 14 via an image bus BUS 12 , a recording control unit 16 for recording therein, and the low color bus ( And a code / decoder 17 connected to the BUS 11 and the image bus BUS 12 for encoding or reconstructing image data.

이와같이 구성되는 종래 팩시밀리의 화상처리장치를 설명하면 다음과 같다.The conventional facsimile image processing apparatus constructed as described above is as follows.

먼저 독취제어부(14)에서 독취된 원고의 비압축화상데이타는 이미지버스(BUS12)를 통해 이미지 메모리부(15)에 전달되어 저장되고, 그 저장된 화상데이타는 다시 이미지버스(BUS12)를 통해 기록제어부(16)로 전달되어 기록되며, 또한 화상데이타는 부호/복호부(17)를 통해 부호화된 후 버스접속부(13)를 통해 시스템버스(BUS10)로 전송된다.First, the uncompressed image data of the document read by the read control unit 14 is transferred to the image memory unit 15 through the image bus BUS 12 and stored, and the stored image data is again stored through the image bus BUS 12 . The data is transmitted to the recording controller 16 and recorded, and the image data is encoded via the code / decoder 17 and then transmitted to the system bus BUS 10 via the bus connection unit 13.

이와같이 구성한 본 발명의 작용효과를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings the effect of the present invention configured as described above are as follows.

먼저, 독취부(100)의 독취제어부(101)에서 원고를 독취하면, 그 독취된 비압축화상데이타는 이미지버스(BUS10)을 통해 이미지 메모리부(102)에 전달되어 저장되고, 상기 이미지 메모리부(102)에 저장된 화상데이타는 부호부(103)의 어드레싱에 의해 부호부(103)로 입력된다.First, when an original is read by the read control unit 101 of the read unit 100, the read uncompressed image data is transferred to the image memory unit 102 through the image bus BUS 10 and stored therein, and the image memory The image data stored in the section 102 is input to the sign section 103 by the addressing of the sign section 103.

이에 따라, 상기 부호부 (103)는 비압축화상데이타를 압축하여 부호화된 압축화상데이타를 독취부호 메모리부(103)에 전달하여 일시 저장시킨다.Accordingly, the encoding unit 103 compresses the uncompressed image data and transmits the encoded compressed image data to the read code memory unit 103 to temporarily store the compressed image data.

한편, 기록부(200)는 시스템버스(BUS201)에서 수신한 압축화상데이타를 제어메모리부(202)에 저장된 프로그램에 따라 진행되는 중앙처리장치(201)의 제어를 바아 버스접속부(204)를 통해 로우컬버스(BUS202)를 거쳐 수신부호 메모리부(203)에 전송하여 일시저장하고, 상기 중앙처리장치(201)의 고속전송 제어신호에 의해 상기 수신부호 메모리부(203)에 저장된 압축화상데이타는 복호부(205)로 전달되어, 원래의 화상데이타로 복원된다.On the other hand, the recording unit 200 controls the central processing unit 201 in which compressed image data received from the system bus BUS 201 is carried out according to a program stored in the control memory unit 202 through the bus connection unit 204. Compressed image data stored in the receiving code memory unit 203 by the high speed transmission control signal of the central processing unit 201 after being transferred to the receiving code memory unit 203 via a local bus BUS 202 and temporarily stored therein. Is transmitted to the decoding unit 205 to restore the original image data.

이와같이 복원되어진 화상데이타는 기록제어부(206)로 전달되어 기록되어진다.The image data restored in this way is transferred to the recording control unit 206 and recorded.

이와같이 기록부(200)의 기록기능에 의해 수신된 화상데이타의 기록이 완료되면, 상기 독취부(100)의 독취부호 메모리부(04)에 저장되어 있던 압축화상데이타는 이미지버스(BUS101)와 로우컬버스(BUS202)는 연결하는 버스스위치부(300)를 통해 수신부호 메모리부(203)에 전달되어 일시저장된후 중앙처리장치(201)의 제어를 받아 복호부(205)로 전달된다.When the recording of the image data received by the recording function of the recording unit 200 is completed in this way, the compressed image data stored in the reading code memory unit 04 of the reading unit 100 is converted into the image bus BUS 101 . The local bus BUS 202 is transferred to the receiving code memory unit 203 through the bus switch unit 300 to be connected and temporarily stored, and then transferred to the decoding unit 205 under the control of the central processing unit 201.

이에따라 상기 복호부(205)는 압축된 화상데이타를 원래의 비압축화상데이타로 복원되면, 상기 이 화상데이타는 기록제어부(206)에 의해 기록되어진다.Accordingly, when the decoding unit 205 restores the compressed image data to the original uncompressed image data, the image data is recorded by the recording control unit 206.

상기에서 설명한 바와같이 본 발명을 독취기능과 수신기록기능을 완전히 분리수행함으로써 원고를 지연없이 독취하여 저장할 수 있고, 또한 전송시에도 독취화상과 상대방 전화번호만 기록되면 다량의 원고를 압축저장하여 수신기록 종료후 원하는 행선지로 전송할 수 있는 효과가 있다.As described above, the present invention can be read and stored without delay by completely performing the read function and the reception recording function. Also, when only the read image and the other party's phone number are recorded, a large amount of the original is compressed and stored and received. There is an effect that can be sent to the desired destination after the end of recording.
