Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an image processing device.

[Prior Art] A conventional image processing apparatus, such as a facsimile machine, sends data read by a data reading section to a destination facsimile machine via a public line, thereby transmitting a read original.

[Problems to be Solved by the Invention] In the conventional device described above, when the original is read as binary data, single character fonts etc. can be read clearly, but it is difficult to read gradations such as photographic originals. There's a problem.

On the other hand, when the above-mentioned original is read as multivalued data by dithering, photographs with gradation can be read clearly, but there is a problem that character fonts etc. become blurred.

SUMMARY OF THE INVENTION An object of the present invention is to provide an image processing device that can clearly read and transmit a manuscript containing a mixture of text fonts and gradation photographic images. It is something to do.

[Means for Solving the Problems] The present invention reads a transmitted document as binary data and also reads multi-value data, stores the read binary data and multi-value data, displays a layout image, and displays the layout image. The above-mentioned binary data and the above-mentioned multi-value data are synthesized based on the following.

[Function] The present invention reads a transmission document as binary data as well as multi-value data, stores the read binary data and multi-value data, displays a layout image, and performs the above operations based on this layout image. Since the binary data and the above multi-value data are combined, a document containing a mixture of text fonts and gradation photo images can be clearly read and sent with both the text font and gradation photo images. .

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

The image processing bag Ht includes a microcomputer 2 that controls the overall operation of the image processing device l, and a memory 3 that stores programs and data operated by the microcomputer 2.
, a reader 4 that reads the transmitted data, a binary reading circuit 5 that reads the analog data from the reader 4 in binary form, a memory 5a that stores the data from the binary reading circuit 5, and an analog signal from the reader 4. A multi-value reading circuit 6 that reads data in multiple values, a memory 6a that stores data from the multi-value reading circuit 6, a communication unit 7 that transmits and receives image data, and a display device that outputs a layout diagram of image data. 8 and an input section 9.

The microcomputer 2 displays a layout image,
This is an example of a data synthesis means that synthesizes the binary data and the multivalue data based on this layout image.

Next, the operation of the above embodiment will be explained.

FIG. 2 is a flowchart showing the operation of the above embodiment.

In addition, FIG. 3 (1) shows an example of a read manuscript, and the same figure (
2) is a diagram showing an example of editing a layout diagram on the display unit 8. FIG.

First, a reading original 41 containing a mixture of character fonts 42 and photographs 43 is set (St), the reading original 41 is read by the reader 4 (S2), and the analog reading data from the reader 4 is transferred to the binary reading circuit 5. writes the binary data to the memory 5a (S3), and at the same time, the multi-value data reading circuit 6 reads the multi-value data from the analog read data from the reader 4, and the memory 6a writes the multi-value data ( S4), In this way, the original document 41 is read up to the last □ line (35).

Then, based on the binary data stored in the memory 5a, the data is compressed to a size that can be displayed on the display unit 8, and character fonts cannot be discriminated.

A layout screen is created that allows the layout of characters, figures, photographs, etc. to be understood (36), and the layout diagram is displayed on the display section 8 (S7).

Then, while referring to the original to be read, use the input device 9 to move the cursor 81 on the screen on the layout drawing of the display unit 8 to select the binary data 82□ binary area and the multivalued data. 83 multi-value areas are determined (38).

After determining the binary region and the multi-value region, the binary data 82 and the multi-value data 83 are synthesized based on these regions (S9), and this synthesized transmission data is transmitted line by line to the communication unit. 9 to the public line (S t O)
, and if there are no more lines to send (S l l)
, the above series of operations ends.

[Effects of the Invention] According to the present invention, it is possible to clearly read and transmit a document in which a text font and a photographic image with gradation are mixed. have
