Abstract

PURPOSE:To prevent a deteriorated processing efficiency and a communication fault by using one interface means to interface plural external devices having different protocols. CONSTITUTION:A controller for a scanner.printers I/F 224 and I/F 223 allows CPU 209 to discriminate types of connected copying machines 103, 104 through 2-way communication. When, e.g. a print command is publicated by a computer 102, a CPU 203 reads and decodes the command and writes the result to a memory 222. The CPU 209 reads the content in the memory 222 and is operated according to the command and gives a print command publication instruction to the I/F 223 and the I/F 223 publicates a command to the copying machine, 103 through communication. The copying machine 103 sends back an image synchronizing signal synchronous with the operation of the printer to the I/F 223. The I/F 223 receiving the synchronizing signal superimposes an image request signal on a signal of a video bus 225 according to the synchronizing signal and sends an image output request to a frame memory 201.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus to which a digital copying machine or the like is connected.

[0002]

2. Description of the Related Art In recent years, digital color copying machines have become popular. Also, a system has been developed in which various interface devices are connected to the digital color copying machine and a print output of an image source from other than the color copying machine can be obtained.

[0003]

However, these digital color copying machines use the printing method, for example,
There are various methods such as an electrostatic photography method and an inkjet method, and the image transfer method and communication protocol are different, so the interface devices connected to them are interface devices unique to each digital color copying machine. Was there. Therefore, for example, in a copy shop or the like that owns multiple types of digital color copying machines, similarly, multiple types of interface devices are required, and each interface device requires a large-capacity image memory. Therefore, the cost was high.

Further, it is usually necessary to periodically communicate between the interface device and the digital color copying machine to recognize the mutual operating states. Therefore, a command or the like is periodically sent from one device, and the status or the like is returned from the other device that receives the command.

On the other hand, when it is possible to connect a plurality of types of digital color copying machines to the interface device,
The processing capacity varies depending on the connected digital color copying machine. In general, a device that receives a command or the like needs to constantly monitor the reception of the command. Therefore, unless the load is smaller than the processing capacity of the CPU or the like, the processing speed is greatly reduced due to such monitoring. Further, if there is a process that cannot be released, there is a risk of causing a communication failure such that the status or the like for the received command cannot be returned. Further, a large load may be applied to only one of the devices, and the processing efficiency may be extremely deteriorated.

[0006]

In order to solve the above-mentioned problems and achieve the object, the image processing apparatus according to the present invention, by switching the image input / output control program according to the type of connection device to be connected, One interface means enables connection to various types or connecting devices such as a plurality of digital color copying machines.

The operation will be described below.

FIG. 2 shows frame memories 201 and 202 and scanner printer interfaces 223 and 224.
FIG. 6 is an explanatory diagram for explaining the details of the above, and the operation when performing scanning and printing. As shown in the figure, the frame memories 201 and 202 have plane memories that store multi-valued data of red, green, and blue (hereinafter referred to as R, G, and B, respectively), and the memory controllers 301 and 30.
2 controls reading, writing, and refreshing. These two memories operate independently, one during printout and the other during C
An image is transferred from the host computer 102 from the PU bus 210, a Postscript image is developed as an example of the page description language described above, or the CPU 2 as described above is used.
Image processing such as rotation and compression using 09 is possible. It is also possible to connect the two and regard them as one memory. This means that, for example, if both have a memory capacity of A4 size, by connecting the two, an image of A3 size can be handled. In the present embodiment, for example, the scanner printer interface 223 is connected to the scanner printer interface 223 via the cable 107.
An electrophotographic color copying machine 103 (hereinafter referred to as CLC method) and a scanner printer interface 224 are connected to an inkjet type color copying machine 104 (hereinafter referred to as BJ method) via a cable 108. To do.

In this case, first, the controllers 303, 30
Reference numeral 8 makes the CPU 209 discriminate by bidirectional communication whether the connected device, that is, the type of copying machine is a device capable of receiving parallel color image data or a device receiving dot-sequential or frame-sequential color image data.
For example, when a print output is obtained from the color copying machine 103, frame sequential color image data is required. Then, for example, the print command is issued by the host computer 1 of FIG.
When issued from 02, the CPU 203 receives the command via the SCSI interface 205. C
The PU 203 interprets this command and writes the received command content in the memory 222 under the control of the bus controller 211. When the CPU 209 recognizes the writing of the command, it reads the contents of the memory 222, recognizes the print command, and executes the operation according to this command. The CPU 209 issues a command for issuing a print command to the color copying machine 103 to the controller 303 in the interface 223, and the controller 303 issues a command to the color copying machine 103 by communication via the cable 107 according to this instruction. In this embodiment, the cables 107, 108, 111 and 112 have the same connection, and the line for transmitting the image data 24 bits, the synchronizing signal, the clock and the command communication are bidirectional, and are accommodated in one cable. . Upon receiving the print command, the color copying machine 103 activates the internal printer, and at the same time sends back an image synchronization signal synchronized with the operation of the printer. The controller 303, which has received the image synchronization signal, operates on the video bus 2 in accordance with the image synchronization signal.
An image request signal is placed on the control bus in 25 to issue an image output request to the memory control 301.
According to the image request signal, the memory control 301 temporarily stores the image data on the video bus 225 in the RGB 24
Bits, that is, R, G, and B colors are output in parallel as 8-bit signals. The output image data is input to the LOG conversion circuit 304 in the interface 223,
The color processing circuit 305 performs image processing for faithfully reproducing an image, such as conversion from an RGB image signal to magenta, cyan, and yellow, masking in accordance with color reproduction of the color copying machine 103, and UCR calculation processing. Are converted into four signals of cyan, magenta, yellow, and black. The color copying machine 103 of the present embodiment is a magenta,
Images are developed in the order of cyan, yellow, and black. Inside the cable 107, 8 bits of the image data of 24 bits are used to transfer the images in a frame sequential manner. Therefore, in this embodiment, the frame memory 2
The RGB image data is repeatedly read from 01, and the color image data of the four color components of cyan, magenta, yellow, and black is output in the frame order.

FIG. 3 shows how the color copying machine 103 forms an image from the image data received from the interface 223. Reference numeral 401 denotes a form of image data stored in the frame memory, for example, a state in which an electrostatic latent image of magenta (M) in a section AB in the drawing is formed on the photosensitive drum 402. A laser light source 403 turns on and off the laser light based on the transferred image data. The turned on and off laser light is reflected by the polygon mirror 404, and the photosensitive drum 402.
An electrostatic latent image is formed on. Reference numeral 406 indicates the rotation direction of the photosensitive drum 402. At this time, the image end is detected by the beam detection sensor 405, and this becomes a horizontal synchronization signal (referred to as HSYNC) to synchronize the image transfer. FIG. 4 shows the state of the timing. These operations are repeated four times in total for cyan (C), yellow (Y), and black (Bk) to form an image. In the above description, the LOG conversion circuit and the masking circuit are provided on the interface 101 side and the frame sequential color image data is input as a color copying machine.

Further, parallel color image data is output to the color copying machine side, and a LOG conversion circuit in the color copying machine is provided.
The processing may be performed by a masking circuit.
In such a case, it is I / O whether the color copying machine is a device for receiving C, M, Y, K frame sequential color image data or a device for receiving RGB parallel color image data.
The F device 101 determines. And the result of such judgment RG
When receiving the parallel color image data of B, the image data line 24 bit inside the cable 107 is fully used, and the RGB image data is transferred as parallel data as shown in FIG.

Further, when outputting the RGB parallel color image data, if the color copying machine has a frame-sequential color printer engine, the RGB parallel color image data is read four times or three times to read the I / F. Automatically switch to output from the device 101.

On the contrary, when an image is taken into the frame memory 201 by using the color scanner of the color copying machine 103,
The image data signal 24 bits in the cable 107 is fully used and transferred as RGB image data. Although not shown, the transferred RGB image data is output to the video bus 225 through the interface 223. At the same time, the controller 303 controls the memory control 30
1 outputs the fetch request signal to the control bus, and the memory control 301 outputs the video bus 225
The image above is taken in and the image is stored in the plane memory based on the request signal. The above is the frame memory 20.
In the frame memory 202, when the controller 303 places a request signal on the control bus with respect to the memory controller 302, the frame memory 202 starts operating similarly. At this time, in order to avoid a bus conflict of the controllers 303 and 304, the scanner / printer interfaces 223 and 224 do not operate at the same time.

Next, a case where an image print is obtained from the color copying machine 104, that is, the BJ type color copying machine will be described.

In the same manner as described above, a command from the host computer 102 causes the controller 306 in the scanner printer interface 224 to move to the video bus 2.
An image request signal is placed on the control bus in 25 to issue an image output request to the memory control 301.
The memory control 301 uses the image data as raster data in accordance with the image request signal and outputs the video data to the video bus
RGB 24 bit is output to 5. The output image data is input to the color correction circuit 307, and color correction is performed according to the characteristics of the printer. The image output from the color correction circuit 307 is temporarily controlled while being controlled by the memory controller 309.
It is stored in the buffer memory 308. This buffer has a capacity for one band for printing shown in FIG. At the same time, a print command is issued to the color copying machine 104. Upon receiving the print command, the color copying machine 104 activates the printer and, at the same time, sends back an image synchronization signal. The memory controller 306 that has received the image synchronization signal, according to the image synchronization signal, RGB24bit
The parallel data is converted into RGB 8-bit point sequential data and output. FIG. 5 shows an explanatory view showing the situation. Reference numeral 501 is print data stored in the frame memory, and is an explanatory diagram in which the shaded area 502 is printed. A roll paper 503 is a roll paper 504.
Feeds the paper in the direction of arrow C as soon as the printing at a constant interval (hereinafter referred to as a band) is completed. Reference numeral 505 is an inkjet head, which is composed of four types of heads of magenta, cyan, yellow, and black. The data sent from the scanner / printer interface 224 as RGB 8-bit point-sequential data undergoes LOG conversion and masking processing in the color copying machine 104, and is printed in the direction of arrow A by the head 505, by a mechanical means (not shown).
Printing is performed by moving in the direction of arrow B. That is, after one band of data is transferred from the frame memory to the buffer memory 308 as raster data in the direction of arrow E, it is converted into RGB 8-bit point sequential data in accordance with the synchronization signal 506 (hereinafter referred to as VE) and the cable 10 is converted.
8 bits of the image data signal of 24 bits are transferred to the color copying machine 104. FIG. 6 shows a diagram for explaining the timing.

FIG. 8 shows a signal structure between the present I / F device and devices such as a color copying machine and a film scanner.

The image signal is transmitted through the 24-bit signal line as described above.

The module 705 controls command communication with the CPU 1 and image transfer control. As a result, the command received from the host computer via the SCSI controller is analyzed on the CPU 209 side, and a processing start instruction is sent to the communication control task or the image processing task.
