Abstract

PURPOSE:To easily raise attention to a receiver side and to send a picture data for its information part with inversion by giving a mark to a mark area corresponding to the information part when there exists the information desired to be informed to the receiver side with emphasis especially in a sent original. CONSTITUTION:A picture signal binarized by a binarizing circuit 2 is inputted also to a subscanning mark detection circuit 4 and whether or not a subscanning mark 12 exists in a subscanning mark area 10 is detected for each line. When the mark exists, a low level as shown in caption 15 in figure from the subscanning mark detection circuit 4 and when no mark exists, a high level is outputted as shown in caption 16 in the figure. Then a low level signal is inputted to a selection circuit 6 from a gate circuit 5 only when an output of a main scanning mark storage circuit 3 and an output of the subscanning mark detection circuit 4 are both at a low level. When the output of the gate circuit 5 is at a low level, the picture data is sent while the polarity of white and black data is inverted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile transmitter, and particularly to a facsimile transmitter that processes read image data.

[Conventional technology]

In conventional facsimile transmitters, the first method converts the image data into binary data of white data and black data based on the reflectance of the document, and sends this data as is to the receiving side, and the second method converts the image data into binary data based on the reflectance of the document. There is also a facsimile transmitter that determines the rate more precisely and can read and transmit multiple colors.

[Problem to be solved by the invention]

In the above-mentioned conventional facsimile transmitter, in the first method, even if the transmitting side emphasizes the content of the document and uses color coding such as red writing, the data is treated as black data (or white data). However, the disadvantage is that the receiving side cannot determine whether the emphasis has been placed or not, and the intention of the transmitting side cannot be fully conveyed. Furthermore, in the second method, the reading circuit and data processing circuit become complicated, making it extremely expensive. Furthermore, since the recipient's receiver must also be able to print in multiple colors, there is a drawback that depending on the recipient's device, this feature may not be fully utilized.

[Means to solve the problem]

The facsimile transmitter of the present invention includes a main scanning mark storage circuit that stores the position of a mark written at the beginning position of a transmission document while transmitting one page, and a main scanning mark storage circuit that stores the position of a mark written at a predetermined position within the effective scanning width. It has a sub-scanning mark verification circuit that detects each line, and a selection circuit that inverts the white and black of the image data read based on the information from the main-scanning mark storage circuit and the sub-scanning mark verification circuit and transmits the resultant image data. are doing.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings. 1st
The figure is a block diagram of one embodiment of the present invention.

In FIG. 1, an image signal obtained by an image reading circuit 1 is converted by a binarization circuit 2 into binary image data of white and black. The converted image data is stored in the main scanning mark storage circuit 3.
However, here, the main scanning mark 11 in the main scanning mark area 9 shown in FIG.
Detects and stores the marked position. Then, the stored contents are output line by line. (14 in Figure 2
) On the other hand, the image signal binarized by the binarization circuit 2 is also input to the sub-scanning mark verification circuit 4, but here, the image signal is input to the sub-scanning mark area 10 shown in FIG. It is detected whether or not there is a sub-scanning mark 12. If there is a mark, the sub-scanning mark verification circuit 4 outputs L as shown in 15 in FIG.
An OW level is output, and if there is no mark, a HIGH level is output as shown at 16 in FIG. Then, the gate circuit 5 inputs a LOW level signal to the selection circuit 6 only when the output of the main scanning mark storage circuit 3 and the output of the sub-scanning mark verification circuit 4 are both at LOW level.

In the selection circuit 6, when the output of the gate circuit 5 is at a HIGH level, the polarity of the binary image data is not inverted between white and black, and is sent as is to the destination receiver via the modem circuit 7. Furthermore, when the output of the gate circuit 5 is at the LOW level, the polarities of the white and black image data are reversed and sent. That is, the main scanning mark area 10 and the sub-scanning mark area 10
If both are marked, the image data of the portion corresponding to the intersection is sent to the receiver side and recorded with the polarities of the read white and black information reversed. As an example, if you send a manuscript as shown in Figure 3(a),
A recorded image like b) can be obtained on the receiving side.

〔Effect of the invention〕

As explained above, in the present invention, when there is information in a document to be transmitted that you want to highlight and notify to the receiving side, by marking the mark area corresponding to that information part,
The image data of the information part can be inverted and transmitted, which has the effect of easily calling attention to the receiving side.
