Description

TECHNICAL FIELD The present invention relates to a first input device for inputting image information,
An input device different from the first input means, which can be connected to a second input device for inputting image information, stores image information input by the first or second input device. The image processing apparatus has a common storage unit for performing the above.

[Prior Art] When storing input information read by a plurality of input devices such as an image information reading device (reader), a microfilm reading device, a VTR, and a magnetic card reader in an image information storage device that stores image information, The input information from a plurality of input devices does not have the same signal format, but differs depending on the input device. For this reason, conventionally, when storing the input information from each input device, it is impossible to take out these input information and output them to the same output device unless they are all converted to the same signal format and stored. .

For this reason, depending on the specifications of the input device and the output device, there is often the case that something that does not need to be converted is always converted into the same signal format and stored, and it is converted back to the original input information, which is very inefficient. Also, the structure was complicated.

[Purpose] The present invention has been made in view of the above-described drawbacks of the related art, and is for forming a visible image based on a plurality of input devices different from each other and image information input by any one of the input devices. In an image processing device connected to a common transmission line in which image output devices are connected in parallel, image information input from the plurality of input devices is stored in a common storage unit, and image output for image formation is performed. An object of the present invention is to provide an image processing apparatus that can efficiently process image information without requiring unnecessary information conversion when outputting to the apparatus.

Embodiment An embodiment according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment according to the present invention. In FIG. 1, reference numeral 1 controls the system of the present embodiment, and performs conversion of read information in accordance with reproduction signals and processing of an information output device. A control unit having a signal processing function, 2 is a CRT display device for displaying image information, 3 is an image information input device (hereinafter referred to as a reader) for reading image information from a placed document, and 4 is for storing image information. An image information storage device capable of reading the stored image information as needed, and is constituted by, for example, a laser disk device. Reference numeral 5 is a microfilm reading device for reading image information recorded on the microfilm.

A block diagram of the control unit 1 is shown in FIG.

In FIG. 2, 11 is a control unit for controlling the entire control unit, 12 is a key input unit, 13 is a display unit, and 14 is a memory, which is connected to the operation control procedure in the control unit 11 and the system of this embodiment. Connection table 14 for various devices
Including a. Reference numeral 15 is an input / output buffer for temporarily holding image information with another connected device, and 16 is conversion of output information from the input / output buffer 15 to an output device (for example, CRT display device 2) so as to match the output format of the output device. An information conversion unit 17 that outputs the output is an interface unit with another connection device.

Hereinafter, the operation of the present embodiment having the above configuration will be described with reference to the flow charts of FIGS. 3 and 4.

FIG. 3 is a flow chart showing image information read out from the reader 3 in the present embodiment, and storage control of the image information in the image information storage device 4 of the read information.

First, in step S1, for example, the image input information is read from the reader 3 from the key input unit 12 of the control unit 1 and a command to store the read image information in the image information storage device 4 is input. According to the operation control procedure stored in the inside, first, in step S2, the reader 3
The reader 3 is requested to output the image information output format format and other processing formats. In response to this request, the reader sends the status information indicating the processing mode of its own device to the control unit of the control unit 1 via the interface unit 17 in step S3.
Send to 11. The control unit 11 generates various processing modes of the reader unit 3 and discrimination code information of the reader 3 based on the status information sent in step S4, and stores them in the connection table 14a in the memory 14. (At this time, if the reader 3 is not ready, wait until it becomes ready.) After that, the control unit 11 instructs the reader 3 to read at step S5. In response to this instruction, the reader 3 scans the document placed on the document table (not shown) in step S6, reads the image information, and sends the read information to the control unit. The image information read from the reader 3 is the interface section.
After being received at 17, the control section 11 adds the discrimination code generated at step S4 to this received information and stores it in the input / output buffer 15. Then, in step S8, it is checked whether or not the document reading by the reader 3 is finished. If the document reading is not finished, the process returns to step S6, the document reading is continued, and if the document reading is finished, the step is finished. Proceed to S9.

At step S9, it is confirmed whether or not the image information can be stored in the image information storage device 4 to which the received image information is to be output, and the transmission data format that can be input. Any kind of data format can be stored in the image information storage device 4. If the preparation for data reception is OK in the following step S10, the process proceeds to step S11, and the image from the reader 3 stored in the input / output buffer 15 is read. A discrimination code is added to the information and transmitted. Then, in step S12, it is checked whether or not all the data has been output. If not, step S12
The process returns to S11, and if completed, the process ends.

The image information format sent from the reader 3 is shown in FIG.

Here, 21a is a vertical synchronization signal (VSYN
C) and 22 are image data for one horizontal scanning, and 23 is a horizontal synchronizing signal (HSYNC) which is a reference for horizontal scanning, and the image data 22 and HSYNC 23 are repeatedly sent for the number of horizontal scanning times. On the other hand, the control unit 11 adds a discrimination code specific to the reader 3 and sends it to the image information storage device 4. The addition of the discrimination code is performed by the information conversion section 16.

FIG. 6 shows a transmission image data format to which this discrimination code is added. Here, 20 is the discrimination code added.

In the above description, the case where the image information read by the reader 3 is stored in the image information storage device 4 has been described as an example, but the present invention is not limited to this, and any input information from any input device can be used in the same manner. A discrimination code can be added and stored in the information storage device 4.

Next, the image information output control will be described with reference to the control flow chart of FIG. 4 in which the image information is read from the image information storage device 4 and is output to the output device (for example, the CRT display device 2).

When there is an instruction input to read the stored image information from the image information storage device 4 and output it to the output device (for example, the CRT display device 2), the process proceeds from step S20 to step S21, and the control unit 11 follows the instruction to store the image information. The device 4 is instructed to the reading start position of the image information to be read and the read image information amount. Upon receipt of the instruction, the image information storage device 4 sequentially sends the corresponding image information to the control unit 1 from the designated read start position according to the instruction in step S22. The control unit 11 of the control unit 1 which has received this image information confirms the discrimination code 20 sent in step S23, and confirms the information format conversion mode so as to match the processing of the output destination device. Then, in the subsequent step S24, the image information sent from the image information storage device 4 is stored in the input / output buffer 15. Then, in step S25, it is checked whether or not the reading from the image information storage device 4 is completed. If it is not completed, the process returns to step S24 and the image information is received and sequentially stored in the input / output buffer 15. When the reception of the image information is completed, the process proceeds from step S25 to step S26, in which the image information stored in the input / output buffer 15 is converted by the information conversion unit 16 so as to match the output format of the output device, and the output device (CRT display device 2 ) Is output.

The output device (CRT display device 2) that has received the image information outputs it as it is (on the display surface).
