Is used to detect the color of the recording paper.

<Explanation of Processing Procedure> A processing procedure of the facsimile apparatus having the above configuration will be described below with reference to the flowchart shown in FIG.

First, when the power is turned on, the CPU 2 advances the processing to step S1 to initialize the whole and waits for the facsimile apparatus to start up in steps S2, S4, S6 and S8. Here, if there is a key 8 input (copy, transmission, function) via the gate array 6, the process proceeds to steps S3, S5, S9, and the process corresponding to the input key is executed. Also, in step S6,
When the NCU 11 detects the call signal from the line 13 and notifies the CPU 2 via the gate array 14,
In step 2, the process proceeds from step S6 to step S7, and the later-described reception process is performed.

Before explaining the receiving process in the embodiment, the process procedure for classifying the color of the recording paper into any of eight colors will be described with reference to the flow chart shown in FIG.

The sensor 16 for detecting the color of the recording paper described above.
The outputs from the (red sensor, green sensor, and blue sensor) are input as R, G, and B, respectively, and the results are determined in step S11 and subsequent steps. First, the determination result in step S11 is Y
If it is ES, the process proceeds to step S12 and Paper_colo
Let r = 00 [hex]. The color of the recording paper at this time is white. If the decision result in the next step S13 is YES, the process advances to step S14 to set Paper_color = 01 [hex], and the color of the recording paper at this time is blue.

Similarly, if the decision result in the step S15 is YES, the process advances to a step S16, Paper_
If color = 02 [hex], the color of the recording paper at this time is green, and if the determination result in step S17 is YES, step S18
The process is advanced to Paper_color = 03 [hex], the color of the recording paper at this time is sky blue, and the determination result in step S19 is YES.
If so, the process proceeds to step S21, and Paper_color = 0
4 [hex], the color of the recording paper at this time is red, step S21
If the determination result in step S23 is YES, the process proceeds to step S23, Paper_color = 05 [hex], the color of the recording paper at this time is purple, and if the determination result in step S23 is YES, the process proceeds to step S24. Proceed to Paper_color = 06 [hex], the color of the recording paper at this time is purple, and if the determination result in step S23 is NO, the process proceeds to step S25 to set Paper_color = 07 [hex]. The color of the recording paper is black.

The contents of Paper_color are stored in the RAM 4 and are referred to in the receiving process described later. Also,
The above-described process of classifying the color of the recording paper may be executed not only in step S1 shown in FIG. 3 but also when the recording paper is set.

<First Embodiment> Next, the processing procedure at the time of reception in the first embodiment will be described with reference to the flowchart shown in FIG.

First, in steps S31 and S32,
The received color image is temporarily stored in the image buffer area in the RAM 4, and when the memory reception for all pages is completed, the process proceeds to step S33 to indicate that the received color image has the same color information as the recording paper. Clear the flag (Same_Color_Flag = 0). And the next step S
At 34, a color check for all pixels of the received color image data is executed.

The detailed processing of this color check will be described with reference to the flowchart shown in FIG. First, step S41
In step S42, the necessary parameters are initialized, and in step S42, the color of the recording paper is white (the value of Paper_color =
0), and if YES, the process is terminated. If the determination result is No, the process proceeds to step S43, and the image data for one pixel is loaded from the image buffer area. Then, in step S44, it is determined whether or not the color matches the color of the recording paper, and if No, the process proceeds to step S46 to advance the reception pixel pointer and prepare to load the next pixel. Next, in step S47, it is determined whether or not the color check of the pixels for one page is completed, and if not completed, the process is returned to step S43, the above process is repeated, and the process for one page is completed. The process returns to step S35 shown in FIG.

On the other hand, in step S44 in the middle, if the color of the recording paper and the color of the receiving pixel match, the process proceeds to step S45, and a flag indicating that the received color image has the same color information as the recording paper. Set (Same_Color_F
lag = 1), and from this process, step S35 shown in FIG.
Return to.

Next, in step S35, it is determined whether or not the color check for all pages has been completed, and if completed, the process proceeds to step S36 to check the state of Same_Color_Flag. Here, if the received color image does not have the same color information as the recording paper (Same_Color_Flag = 0), the process proceeds directly to step S38. However, if it exists (Same_Color_Flag = 1), the process proceeds to step S37 to activate the speaker driving unit 17 to audibly notify the user of the color check alarm by the speaker 18 or visually by the LED 7. After that, step S
In S38 and S39, the image recording of all pages, which will be described in detail later, is performed, and the reception process ends.

As described above, according to the first embodiment, by providing the color sensor of the recording paper, the recording paper is not white, the received image is color, and the received color image is recorded on the recording paper. When the same color information is included, it is possible to audibly or visually issue a warning to the user.

<Second Embodiment> Next, a detailed processing procedure at the time of reception in the second embodiment will be described below with reference to the flowchart shown in FIG.

First, in steps S51 and S52,
The received color image is temporarily stored in the image buffer area in the RAM 4, and when the memory reception for all pages is completed, the process proceeds to step S53, and the color of the image data received in the memory is corrected.

The detailed process of this color correction will be described with reference to the flowchart shown in FIG. First, in step S61, necessary parameters are initialized, and in the following step S62, the color of the recording paper is white (the value of Paper_color =
0), and if YES, the process is terminated. If the determination result is No, the process proceeds to step S63, and the image data for one pixel is loaded from the image buffer area. Then, in step S64, it is determined whether or not the color matches the color of the recording paper. If No, the process proceeds to step S66 to advance the reception pixel pointer and prepare to load the next pixel. Next, in step S67, it is determined whether the color check of the pixels for one page is completed, and if not completed, the process is returned to step S63, and the above process is repeated. It returns to step S54 shown in FIG.

On the other hand, if the decision result in the above-mentioned step S64 is YES, the process advances to step S65, the color changing process described later is performed, and the process advances to step S66.
When the process returns to step S54 shown in FIG. 7 and the color correction of all pages is completed, the process proceeds to steps S55 and S56 to record all pixels.

FIG. 9 is a flow chart showing details of the above-mentioned color change. First, in step S71, the value of pixel_color, which is the color information of the loaded pixel, is decremented by 1,
In the next step S72, the color is rewritten by re-storing the value in the address of the image buffer area. For example, if green recording paper is set and the received image is green (pixel_color = 2), change the color to blue (pi
xel_color = 1) Print on green recording paper so that the image can be read.

As described above, according to the second embodiment, there is an effect that the color of the portion of the same color information as the recording paper can be changed and recorded.

<Modification of Second Embodiment> In the above-described second embodiment, the color is changed by reducing the value of the color information by one, but in this example, the color information is changed to white. To do.

FIG. 10 is a flowchart showing a modification of step S65 shown in FIG. In step S81, the color information of the pixel that matches the color of the recording paper is set to white (pixel_
color = 0) is set, and in step S82, the value is re-stored in the address of the image buffer area to rewrite the color.

As described above, according to the modification, for example, when green recording paper is set and an image consisting of only three colors of red, green and blue is received, red and blue are recorded and the recording paper is recorded. It is possible to save the green recording material (ink, toner, etc.) by correcting so as not to record the same color of green.

<Description of Recording Process> Next, the recording process described above will be described below with reference to the drawings.

FIG. 11 is a diagram showing the structure of the color recording head 21 in the embodiment. As shown in the drawing, recording is performed by spraying three inks of R, G and B on the position of one pixel. is there. Then, when printing (recording) of one pixel is completed, the position of the color recording head 21 is changed one after another to continue printing, thereby realizing recording in page units. The scanning in line units is performed by the recording motor 24 conveying the recording paper. In this figure, GREE
It is a place where sky blue pixels are recorded by spraying ink of N and BLUE.

FIG. 12 is a flow chart showing the detailed processing procedure in step S37 shown in FIG. 5 and step S55 shown in FIG.

First, in step S91, necessary parameters are initialized (for example, the recording head 21 is moved to the initial position), and in step S92, color data of pixels to be recorded is loaded. Next, in step S93, printing processing for one pixel, which will be described in detail later, is performed, and in step S94, the pixel pointer is incremented. Then, in step S95, it is determined whether or not the printing (recording) process for all the pixels for one page has been completed. If not completed, the process returns to step S92, and the above process is repeated.

FIG. 13 is a flow chart showing the detailed processing in step S93 of FIG. As shown, steps S101, S103, S105, S10
7, S109, S111, S113, pixel_color
Pixels are color-coded according to the value of. For example, if YES in step S101, the process proceeds to step S102 to turn off the spraying of RED, GEEN, and BLUE shown in FIG. In other words, in this step S102, the pixel is white, so it is not printed. Also, step S103
If YES, the process proceeds to step S104 and ON
BLUE (blue) ink is sprayed, and the pixel is printed in blue.

Similarly, the following steps S104 and S10
6, S108, S110, S112, S114, S11
In 5, the ink which is ON is sprayed, and the pixel is printed.

In the above-described embodiment, the case of recording the received color image has been described as an example, but the present invention is not limited to this, and can be applied to the case of copying an original, for example.

The present invention may be applied to a system composed of a plurality of devices or an apparatus composed of a single device.
