Abstract

PURPOSE:To confirm stored picture information at the high speed with a monitor before printout or while being printed out by accessing the stored picture information and controlling the access so that the information is displayed in face-sequentially. CONSTITUTION:When a picture read signal is inputted from a CPU board CPUB 101 to a scanner printer interface SP I/F 105, a picture R data is written to a page memory PMR 102 by one page memory. Then the R data from the memory PMR 102 is read by one picture element and stored in a direct memory access controller DMAC 106 and transferred to a monitor frame memory FM/DA 107. Since the frame memory FM/DA 107 displays the content of the memory on a monitor 110 even a CPU board CPUB 101 or DMAC 106 is accessed, the picture element data stored sequentially in picture elements are subjected to D/A conversion and the result is displayed on the monitor 110. Thus, the picture sent and received is monitored.

Signals ITOP, BD, VCLK, VID in Figure 2
E.O.

H3YNC and SRCOM (511-516) are interface signals between the color printer section 2 and scanner section 1 in FIG. 1, respectively. All of the image signals VIDEO 514 read by the scanner section 1 are sent to the color printer section 2 along with the above signals. ITOP is a synchronization signal in the image sending direction, and is sent once for sending one screen.
That is, the transmission of images in four colors (yellow, magenta, cyan, and black) occurs once each, for a total of four times. When the toner image is transferred at the contact point with the drum 715, the image at the leading edge of the document should match the position (the transfer drum 716 is synchronized with the rotation of the photosensitive drum 715, and the video processing in the scanner unit l). unit 1

VCL
K513 is a synchronous clock for sending an 8-bit digital video signal 514 to the color printer section 2, and sends out the video data 514 via a flip-flop circuit. H3YNC515 receives VCLK from BD signal 512
The VIDEO signal 514 is a main scanning direction synchronization signal generated in synchronization with H3YNC 513 and has the same period as BD, and strictly speaking, the VIDEO signal 514 is sent out in synchronization with H3YNC 515. This is B
Since the D signal 515 is generated in synchronization with the rotation of the polygon mirror, it contains a lot of jitter from the motor that rotates the polygon mirror 712. If the BD multiplied signal is synchronized as is, jitter will occur in the image, so the BD multiplied signal is generated in synchronization with the rotation of the polygon mirror. ISYNC5 (generated synchronously with jitter-free VCLK)
This is because 15 is required. SRCOM is a signal line for half-duplex bidirectional serial communication, and it carries instructions from the scanner unit 1 to the printer unit 2, such as color mode, cassette selection, etc., and status information of the printer unit, such as jam, out of paper, etc.
All information such as weights is exchanged via this communication line SROOM.

(Image Data Input) The SCA/PR 1109, which is composed of the scanner section 1 and the printer section 2 as described above, is connected to the SPI/F 105 that is its interface. sP1
/F105 receives an instruction to read an image from the CPU board CPUBIOI via the system bus 111.
Start CA/PR 1109 and read the image.

The SCA/PR 1109 is a frame-sequential scanner/printer, and each color component R (red), G (green), and B (blue) is input and output one page at a time.

The scanner/printer interface SPI/F 105, which has received the instruction to read the image, becomes the bus master and directly transfers the image data to the system bus 1 in real time.

The image is transferred to the scanner/printer SCA/PR 1109 by interfacing the CA/PR 1109.

Scanner/printer interface SPI/F105
is from the CPU board CPUBIOI to the system bus 111
When an image write instruction is received via
Scanner/printer SC sequentially from each board of MB104
Image data is output for each color to the A/PR 1109.

At this time, the CPU board CPUBIOI is waiting for an interrupt, and when the image output to the printer is finished, the scanner/printer interface SPI/F105 generates an interwoven signal on the system bus and transfers control to the CPU board.
Pass it to the U board CPUB101.

(Image display) Image data is stored in page memory PMR102゜P.
MG103. The PMB 104 stores color data for each color in a separate address space as shown in FIG. 4(B), and the monitor frame memory FM/DA 107 stores color data as shown in FIG.
As shown in A), three colors of image data (R, G, B) are mapped to the same address space.

That is, in the former case, when the memory is addressed, one of R, G, or H data is shown, and in the latter case, R, G data is shown.

Data packed in three colors (B) is shown. The former will be referred to as a frame-sequential memory, and the latter will be referred to as a pixel-sequential memory.

Next, control of image display will be explained using the flowchart shown in FIG. In step Sl, as described above, CP
Scanner/printer interface SPI/F10 from U board CPU BIOI via system bus 111
When an image read signal is input to the scanner/printer interface SPI/F 105, the scanner/printer interface SPI/F 105 starts up the scanner printer SCA/PR 1109. Then, the R data of the image is written to the page memory PMR for one page memory. Similarly, step S2. In S3, G data and B data are each stored in page memory PMG10.

If it has not been transferred, the process returns to step S4 to transfer the next pixel data, and steps 84 to S9 are repeated until the pixel data is transferred. When the transfer of one page's worth of image data is completed, the DMA controller DMAC106 generates an interlaced signal on the system bus 111 and passes control to the CPU board CPUBIOI.

[Other Examples]

FIG. 6 is a system configuration diagram for explaining a second embodiment of the present invention.

In the following description, differences from the first embodiment described above will be explained, and explanations of common parts will be omitted.

In the second embodiment, in addition to the system bus III, page memories PMR102, PMG103. PMB104
and scanner/printer interface SPI/F10
An express bus 112 will be provided between 5 and 5.

(Image data input) In the second embodiment, the scanner/printer SCA/PRI
109 and input to the scanner/printer interface SPI/F 105, the image data is sent to the page memory PMR 102゜P for each color via the high speed bus 112.
MG103. It is transferred to PMB104.

(Output of image data) Page memory PMR102゜P captured in this way
MG103. In order to obtain the image data of the PMB 104 as a hard copy, the image is transferred to the scanner/printer SCA/PRi 109 using the scanner/printer interface SPI/F 105 as an interface. Since the SPI/F 105 does not have a page buffer, images are transferred between the page memories PMR 102, PMG 103, PMB 104 and the printer of the SCA/PR 1109 in real time. At this time, page memory PM
R102, PMG103. PMB104 and SPI/F
The flow of image signals during 105 is performed using a high speed bus. SPI/F105 is SCA/PRi109(F)
The color components being printed by the printer are output as high-speed bus control signals, and the PMR102, PMG103. Each board of the PMB 104 determines whether it is selected based on its control signal, and if it is selected, outputs an image for each horizontal raster in synchronization with a synchronization signal output by the SPI/F.

(Image Display) In the second embodiment as well, a frame-sequential memory is used as the page memory, and a pixel-sequential memory is used as the monitor frame memory. A control flowchart for image display is shown in FIG. Also scanner/printer SCA/PR1109
and page memory PMR102゜PMG103.
A timing chart of DMA from the PMB 104 to the frame memory FM/DA 107 is shown in FIG. In the system shown in FIG. 6, high-speed bus 112 and serial bus 1
Since it has two buses of 11, image data can be sent to two buses at the same time. Taking advantage of this, image reading by the scanner/printer SCA/PRI 109 and image data transfer by the DMA controller DMAC 106 are performed simultaneously. .

In step S10, the CPU board CPUBIOI
.

Scanner/printer interface SPI/F105
When an instruction to read an image is issued, R data is written to the page memory PMR 102 in real time via a high-speed bus. When writing of R data for one page is completed, the DMA controller DMAC106 detects the write end signal output on the system bus 111 in step S14, and transfers the data from the page memory PMR102 to the monitor frame memory FM/ in step S15. D.A.
The image data is transferred to the frame memory on 107 via the system bus by DMA. Here, since the frame memory is a pixel sequential memory, the G and B areas are masked and data is written so that only the R data (8 bits) area is accessed at the same address in FIG. 4(A). It is necessary to make sure that there is no such thing.

Next, while the DMA controller DMAC106 is performing step S15, the CPU board CPUBIOI again transfers the page memory P via the high-speed bus in step Sll.
Write G data to MG103. Then, while the G data is being written to the page memory PMG103, step S15 ends and the DMA controller DMAC10
Step 6 waits for the end of step Sll. Step 314~
15, when detecting the end of step Sll in step S16, the DMA controller DMAC106 executes step S17, and in parallel thereto, B data is transferred from the scanner/printer SCA/PR 1109 to the PMB 104 in step S12.

When the transfer is completed, in steps S18-19, the DM
Frame memory F by A controller DMAC106
DMA transfer is performed to M/DA107, and finally R, G
.

The image data of B is transferred to the monitor frame memory FM/DA, and the image is displayed on the monitor 110. This frame memory FM/DA107 has 2 memories.
It serves as memory for the port, and even when an image is being displayed on the monitor 110, it is transferred to the CPU board via the system bus 111.
UBIOI or the DMA controller DMAC 107 can write image data, and the display screen will not be disturbed. Therefore, at the end of step 315, R
The data is displayed on the monitor 110, R and G data are displayed at the end of step S1, and R and G data are displayed at the end of step S19.
, G, B full-color images are displayed on the monitor 110. Looking at the time flow of each operation, the time chart is shown in Figure 8.

As described above, by providing two buses, the time required to read the document from the scanner and display it on the monitor can be significantly shortened. Furthermore, at the end of one scan out of a total of three scans of R, G, and H, the entire image can be confirmed, albeit in a single color of red (R).

FIG. 9 is a diagram for explaining the third embodiment.

In the second embodiment, page memories PMR102, PMG
103゜PMB104 to monitor frame memory FM
The DMA controller DMAC 106 transfers images to the /DA 107 in a frame-sequential manner. At this time, the monitor 110 first displays R data, then R and G data, and finally R data.
lG, B Full color images are displayed.

In this embodiment, the monitor frame memory FM/DA107
When displaying an image on the monitor 110 from the image data 113 and the R, G, B lookup table RLUT 122. as shown in FIG. GLUT123. A selector 117 is provided between the BLUT 124 and the BLUT 124. The flow of image data is

Lookup table GLUT123 for n and lookup table BLUT124 for blue are entered, and after data conversion is performed, the D/A converter 125. 126.12
7, the data becomes analog data, is input to the monitor 110, and is displayed on the monitor 110.

The selection signal 11B is sent to the DMA controller DMAC106.
Trigger R, G, and B DMA transfer performed by
Change as shown. Then, according to the selection signal 118, by changing the input and output as shown in the figure, when displaying the screen sequentially, a black and white image is displayed on the monitor for the first and second display, and a full color image is displayed for the third display. The image is displayed.

Furthermore, it is clear that various displays can be made by changing the contents of the input/output table in the table of FIG.

In the second embodiment, only R data is displayed during frame-sequential display, or only R and G data are displayed, so there was a problem that it was difficult to see depending on the symmetrical image. Providing a selector between the lookup table and the lookup table has the effect of making the display easier to see.

[Effects of the Invention] As described above, according to the present invention, image information read for printing can be checked at high speed on a monitor before or while printing out. Particularly with facsimile machines, this has the effect of making it easy for the sender to check whether the information they are trying to send has been read correctly, and for the receiver to be able to discover defects in the received information without having to actually print it out. This has the effect that it is possible to determine whether it is really necessary to print out the information.
