Abstract

PURPOSE:To visually confirm the image information without wasting paper by displaying an image before encoding which is read by a scanner on a display device. CONSTITUTION:A scanner 101, is constituted so that it can read a color image, and outputs multi-value signals of 8 bits, respectively of red, green and blue (R, G, B) as image signals. A display part 107 is placed on an operation panel 114, and displays display data from a display control part 108.

The disadvantage is that paper is wasted.

Also, when receiving documents, all documents are output from the printer.
This has the disadvantage that unnecessary information is also output, resulting in wasted paper.

Each parameter of the operation mode of the printer 102 is set to 04, and the operation of each part is executed according to the contents.

First, according to the contents of the parameters, the hard disk interface 110. Each mode instruction of the decoder 116 and printer interface 104 is output (3181-5
183), then hard disk interface 116
．． Decoder 10B, printer interface 104,
Each operation command is output (5184 to 5186),
Images are transferred from the hard disk 111 and sent to the decoder 10.
6, the raw image is decoded in a predetermined operating mode, and the raw image is output to the printer 102 via the printer interface 104 to obtain an image.

Then, the CPU 113 ends the process when one page is completed (S187 to 51B9).

FIG. 21 is an f70-chart showing the "print page memory" subroutine called in each of the above flowcharts.
Parameters instructing the operation mode of the printer 102 are set in the printer 102, and the printer 102 operates according to the contents.

First, after an area instruction and a read mode are set in the page memory 109 (5191), a parameter mode instruction is output to the printer interface 104 (5191).
92), an operation command is output to the printer interface 104, raw image data is transferred from the page memory 109, and is output to the scanner interface 103 via the printer interface 104 to obtain an image of one page (5193.5194).

In the above embodiment, when transmitting a monochrome image, the color/monochrome converter 202 generates a Y signal from RGB data and uses it as monochrome data. However, instead of generating the Y signal in this way, , RGB data may be selected and used as black and white data. In this way, the color/black and white converter 202 is unnecessary and the circuit configuration of the scanner interface can be simplified. Note that with this configuration, if you want to send a color original in black and white, there is a possibility that you will not be able to obtain a proper black and white image. It is possible to perform processes such as copying a document, creating a black and white document, and re-sending it. However, in reality, such cases are considered to be rare.

Furthermore, as another embodiment, instead of using a hard disk as the image storage memory, a semiconductor memory such as a DRAM or a magneto-optical disk may be used.

It is also possible to eliminate the page memory 109 for storing raw images and to perform all image transfer from the image memory (hard disk).

Furthermore, when reading a document, it is also possible to directly transmit the read image from the CCU without storing it in the image memory. Furthermore, when reading a document, a binary main document can be stored in one image memory.

[Effects of the Invention] As explained above, according to the present invention, by displaying a read image and a received image on a display device, an operator can confirm each image without making a hard copy, and unnecessary printouts are no longer necessary. This has the effect of saving paper.

In addition, by using a raw image that has been converted from multilevel halftone to binary halftone for facsimile communication as the image displayed on the display device, it is possible to display an image that is close to the actual output image, and the image can be accurately displayed. There is an effect that can be grasped.
