Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication terminal device such as a facsimile machine and a multifunction machine having multiple functions such as a fax function and a copying function.
[0002]
[Prior art]
In general, a communication terminal device such as a facsimile machine has a function of reading an original by an image reading unit, a communication function of transmitting or receiving a read original or stored data, and a function of printing a read original or received data. I have.
[0003]
In this type of facsimile apparatus, when a document image is read and transmitted by fax, TTI processing (adding a transmission source) is performed. Conventionally, this TTI process creates an image by converting the source character into the image memory of the system, transfers the data to the image memory with a scanner or a communication codec (CODEC), and codes the image from the image memory with the codec. And stored in the ECM buffer of the image memory. Then, the read document image is encoded following the ECM buffer.
[0004]
[Problems to be solved by the invention]
In the facsimile apparatus having the above-described image reading function, communication function, and printing function, there is a demand for operating the plurality of processes simultaneously in parallel for speeding up the processes. In order to meet these demands, an encoding codec is provided for each of image reading, communication processing, and print processing. However, providing at least three codecs to execute at least three different functions simultaneously has the problem of increasing the cost of the apparatus.
[0005]
On the other hand, in the conventional facsimile apparatus, when transmitting a sender with an original image, if the sender is required to be stored in the image memory, there is a problem that the read image cannot be printed or the list print cannot be performed at that time. .
[0006]
The present invention has been made paying attention to the above problems, and an object thereof is to provide a communication terminal device capable of image printing and list printing even during scanner real-time transmission.
[0007]
[Means for Solving the Problems]
A communication terminal device according to the present invention includes an image memory, a communication unit that exchanges data related to the image memory via a communication unit, a recording unit that records image data, and an image reading unit that reads an original image. The communication codec, an image storage unit provided in the image memory, a font image buffer and a communication buffer, means for converting characters stored in the image storage unit of the image memory into an image, and the image reading An image memory for storing an image read by the unit and a second codec different from the communication codec, and encoding the converted character image with the communication codec for the communication The image is stored in the buffer, and then the image of the original image is transferred from the image memory to the communication codec. Enter the coded stores in the communication Baffua, the image of the original image read by the image reading unit, or through the second Kodeikku data of said image memory, and stored in the image memory The accumulated data is recorded by the recording unit.
[0008]
In this communication terminal device, an image converted from TTI is stored in a communication buffer via a communication codec without being placed in an image memory, and subsequent read image data is transmitted from the image memory via a different input of the communication codec. Therefore, image printing, list printing, etc. can be executed in parallel.

A scanner processing unit 12, an image memory (SDRAM) 13, an image processing unit 14, a printer control unit 15, an LED printer 16, and a bus 17.
[0010]
CPU1 controls each part which comprises this apparatus. The NCU 2 controls a connection with the telephone line network (PSTN) 19 and has a function of transmitting a dial signal corresponding to a telephone number (including a FAX number) of a destination and a function of detecting an incoming call. . MODEM3 is an ITU (International Telecommunication Union) -T recommendation T.264. 30 based on the facsimile transmission control procedure according to 17, V. 27ter, V.I. 29, the transmission data is modulated and the received data is demodulated. Further, in addition to these, V.V. 34, the transmission data is modulated and the received data is demodulated.
[0011]
The ROM 4 stores a program for controlling the apparatus, image data for each character, and the like. The SRAM 5 temporarily stores data and the like. The image memory (SDRAM) 6 has storage areas such as an ECM buffer (communication buffer), an image storage unit, and a font image buffer, and stores image data. The operation unit 7 allows the user to perform instruction operations such as FAX transmission / reception, printing, and image reading. The printer / scanner CODEC 8 encodes (encodes) the image data using the MH, MR, MMR method, or the like when printing the image data or when reading the data but storing the data in the image memory 6. The communication CODEC 9 encodes the received image data by MH, MR, MMR, etc. in order to transmit the image data, and decodes (decodes) the received image data. The display unit 10 displays command information such as key buttons, warning information, and other information.
[0012]
The CCD scanner 11 reads the image data of the original when sending a fax or copying. The scanner processing unit 12 performs image processing on the document read by the CCD scanner 11 and stores it in the image memory 13 and the image memory 6.
[0013]
The image memory 13 stores an image read by the CCD scanner 11, image data received from the image memory 6, and the like. The image processing unit 14 performs image processing related to the scanner control unit 12, the image memory 13, the printer control unit 15, and each unit connected to the bus 17.

A case will be described in which facsimile transmission with a sender name is performed in the facsimile apparatus of this embodiment. The TTI (source) image stored in the font image buffer of the image memory 6 is input to the communication codec 9. That is, here, the TTI (source) is not extended to the image memory 13, but the TTI is input from the image memory 6 to the communication codec 9, encoded, returned to the image memory 6, and the ECM buffer ( Stored in the communication buffer). Subsequently, the original image read by the CCD scanner 11 is stored in the image memory 13 via the image processing unit 14. Then, it is input from the image processing unit 14 to the communication codec 9, encoded, and stored in the image memory 6 behind the TTI of the ECM buffer. The TTI and read image data of the ECM buffer are transmitted via MODEM 3 and NCU 2. FIG. 2 shows the flow of TTI data and the flow of document read image data. In FIG. 2, a route indicated by a solid line A indicates a TTI data flow, and a route indicated by a broken line B indicates a document image reading data flow.
