Abstract

PURPOSE:To make an interface for a printing means into simple constitution by storing picture information while reading a storage area adjusted to the printing size of a storage means as a white pattern and outputting picture information in correspondence with a picture clock from the printing means. CONSTITUTION:The storage area adjusted to the printing size of the printing means 3 is secured in a second storage means 4, and the storage area is set to be the white pattern. Then, picture information which is read from a first storage means 1 is stored in the storage area which is set to be the white pattern. Picture information are outputted for every scanning line in correspondence with the picture clock from the printing means 3, and printing is performed in correspondence with picture information which has been outputted. Consequently, a mainbody-side has only to adjust the output size to a printer device-side, and it does not require control of line switching. Thus, the printer interface can be made with simple constitution.

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image processing device such as an image information filing device that performs image information registration, search, etc., for example.

(Prior Art) Recently, image information such as documents, which are generated in large quantities, is read by optical two-dimensional scanning using a two-dimensional scanning device (scanner), and this read image information is stored on an optical disk. An image information filing device has been put into practical use that searches for and reads out arbitrary image information in the image data, and uses an interface to output the read image information in a state where it can be viewed by an output device such as a CRT display device or a printer.

In such a device, for example, if the printer prints on A3 size paper, there is a possibility that it will print an image of A4 size, B4 size, etc., which is smaller than the print size.

In this case, if the printer line can be switched from the interface on the main body side, printing as described above can be performed, but the interface on the main body side requires a circuit for controlling this.

Furthermore, if the printer itself performs line switching, it is necessary to convert A4 size image information into A3 size image information and output it using an interface on the main body side.

In this case, if the main unit does not convert A4 size image information into F3 size image information, two lines of image information supplied from the main unit will be treated as one line on the main unit, as shown in Figure 6. This is because there is a problem that the image may be printed incorrectly and the image may be washed out.

Therefore, it is necessary to perform line switching control or size conversion of one line of image information using the interface on the main body side, and there is a problem that the interface becomes a complicated circuit.

It stores search data consisting of storage addresses, image sizes, etc. on 20.

Next, the operation of image information storage and retrieval processing in the electronic filing device with such a configuration will be described. First, storage processing of image information will be explained.

For example, the user selects and sets the registration mode using the keyboard 23 and manually searches for image information to be stored on the optical disc 20.

This search information is composed of a plurality of search key items, and the contents of the search key items are set in advance. The CPU 34 checks the validity of this manually generated search information according to a predefined format. Furthermore, compared to the search information already stored on the optical disc 20, there is double registration.

perform the process. Depending on the result of this check, the manually entered search information is stored in the main memory 13.

Next, the original is set on the scanner device 18, and the CPU 34
operates the optical disk device 22 and scanner device 18. The scanner device 18 two-dimensionally scans and photoelectrically converts image information such as a set document. Line information of this photoelectrically converted image information is sequentially stored in the page memory 40.

The image information stored in the page memory 40 is stored in the display memory 42 and displayed on the CRT display device 24. The user checks the skew, density, resolution, etc. of the image information displayed on the CRT display device 24, and when the displayed image information is satisfactory, inputs a memory key (not shown). Then, the CPU 34 converts the image information stored in the page memory 40 into a well-known MR (
Encoding processing is performed by band compression using a Modified Read method or the like. This encoded image information is supplied to the optical disc device 22 and stored on the optical disc 20.

When the image information has been stored on the optical disk 20, the CPU
34 is a search code (a search code (
search information) and stored in the main memory 38.

Next, the CPU 34 supplies the search data stored in the main memory 38 to the magnetic disk device 27. Thereby, the magnetic disk device 27 stores the supplied search data in the magnetic disk 26.

Next, the search process for image information stored on the optical disc 20 will be explained with reference to the flowchart shown in FIG. First, a search mode is set using the keyboard 23, and search information corresponding to the image information desired to be searched is input. The CPU 34 sequentially compares and collates the input search information with the search information stored on the magnetic disk 26, and sequentially checks whether search information that matches the manually entered search information is stored. And CPU34
, the logical address corresponding to the search information that matches the input search information is read out.

The CPU 34 calculates a physical track address and a physical sector address corresponding to this address, and uses these addresses to cause the optical disc device 22 to reproduce image information from the optical disc 20. Further, the CPU 34 supplies image information (compressed information) for each scanning line supplied from the optical disk device 22 to the compression/expansion circuit 50, performs band expansion processing, and sequentially supplies the image information to the page memory 40. This results in
The retrieved image information is stored in area A of the page memory 40. The image information stored in area A1 of the page memory 40 is displayed on the CRT display device 24 using the display memory 42.

When the image information displayed on the CRT display device 24 is instructed to print out using the keyboard 23, for example, it is supplied from the page memory 40 to the printer device 2'3 via the printer interface 54, and from this printer device 25. It will be printed out.

That is, the CPU 34 determines the print size based on the size signal from the printer device 25, and reserves area B (corresponding to, for example, F3 size) in the page memory 40 as a storage area corresponding to the determination result. Next, CPU3
Step 4 clears all the contents of area B with a white pattern (white data). Next, the CPU 34 writes the contents of area A into area B (see FIG. 3). This A4 size image may be stored at any position within the A3 size. The image information stored in area B is then stored in buffer memory 54g within printer interface 54. The image information stored in the buffer memory 54a is stored in the buffer memory 54a according to the image clock from the printer device 25.
The data is converted into parallel data by the serial-parallel conversion circuit 54b and output to the printer device 25. As a result, as shown in FIG. 5, the printer device 25 prints the retrieved image information, and prints other parts as blank spaces (white printing).

Therefore, if the line switching of the output image to the printer device 25 is performed using the image clock from the printer device 25, the main body side only needs to match the output size to the printer device 25 side, and there is no need to control line switching. Therefore, the printer interface 54 can have a simple configuration.

As mentioned above, the actual image searched is A4 size,
When the print size of the printer device 25 is larger than A3 size, the A3 size range other than the A4 area is output as white data, so the image information retrieved only by the line switching signal (image clock) from the printer device is You can also print small images on large sheets of paper. As a result, the main body only needs to match the output size to the printer side, and there is no need to control line switching.
The printer interface can have a simple configuration.

Furthermore, there is no need to provide a line switching circuit on the main body side, that is, on the printer interface, and it is possible to output images of any size.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide an image processing apparatus in which the interface 7 for printing means can have a simple configuration.
