Description

[Detailed description of the invention]

[Industrial Application Field] The present invention is applicable to digital copy machines, digital plate making machines, mimeograph machines that integrate a J plate making machine and a printing machine, etc.
Regarding the image processing (editing) function, when performing image processing operations, it is necessary to correct the misalignment of the setting position of the original image in the original image input section. The present invention relates to an image processing method and an image processing apparatus suitable for implementing the method, in which the positioning and operation of the image processing apparatus can be omitted.

[Prior art]

As one aspect of conventional image processing technology, image processing operations such as text/photo, blank/bottom mode switching of image input signals, masking designation, or envelope character designation are performed on part of the original image. In some cases, the original is sent to a pen-input device, generally called a digitizer, and each area to be processed is specified, and the source of that area is The L; l position is stored in the digitizer, and then the original is set again on the image reading section of the image output device of the digital copy machine or digital plate making machine section, and the signal from this image reading section and the signal from the digitizer are combined. By overlapping and outputting, the most
:3- It is possible to obtain images that have been processed (edited) according to the agreement (3).It is also possible to use a word processor, a personal combination, or a computer equipped with a printer as an image output section and an image scanner as an image input section. As for various image processing functions, there is also one that displays images on a Toso I/7 matrix liquid crystal display section or a CRT (cathode ray tube) display section, and performs image processing (editing) while being linked to a monitor.

[Problems to be solved by the invention]

By the way, in the above-described method of performing image processing using a digitizer, the original setting operation is performed in two stages, and the position of the original set on the digitizer and the position of the original set on the image output device are both If there is an equivalent positional relationship from the base point of 0, which is the same position in the device, the position of the image processing target area will be stored in the digitizer and the position of the image processing target area will be 1 in the output image. .this[
- In order to prevent position error-1, it is necessary to create a new position alignment mechanism (J) or do not perform that operation (1). A processor or a personal indicator reads an original image, stores the input high-resolution image data signal as it is and displays it on the display, and then converts the image data signal as high-resolution data. Since image processing is performed by performing image processing, a large-capacity memory means is required to store an amount of data that can correspond to the input high-resolution image data. This method was devised to effectively solve these problems in view of the problems of the prior art, such as: ) and to provide an image processing method that can reduce the capacity of a memory means for storing image data for specifying an image processing target area, and an image processing apparatus that implements the method.

[Means to solve the problem]

The image processing power method according to the present invention involves first reading a striped image optically, converting the optical code into first image data that is an electrical signal, and zumbling the first image data. (2) storing the second image data in a first memory means, displaying the output from the first memory means (No. 5-1 as a monitor image on a display means, specifying an image processing target area for the monitor image in the display stage; storing the specified saw image processing target area, I, and the image J1 processing target area other than the processing target area in the second memory means; The optical signal obtained by optically reading the Haraaki image for the second time is converted twice into "1 first image data, and the second first image data is converted into -1, memory 2 information stored in the memory means + 1 series". Accordingly, if lr, partial data of the 17.1 first image data twice in the area corresponding to the foot fixation processing target area are processed in the desired image processing mode y11?if-□=
1.1. The third image image processed by the data processing is inputted to a desired image output section). Furthermore, the image processing apparatus according to the present invention includes a manuscript input means for converting a manuscript reading signal obtained by optically reading a manuscript image into an Ichiki Meigo, and a first image converted into an electric signal by the manuscript input means. a data lowering means for converting the data into second image data of lower resolution; and a first memory means for storing the second image data; a display means for displaying the stored second image data as a monitor image; an area signal input means for specifying an image area for image processing on the monitor image of the second image data; A second area in which the solid image processing target area and the image non-processing target area are input.
The second first image data newly outputted from the memory means and the original input means is handled as data to be processed, and the 1st and 11th Orients are placed in the image processing target area according to the information stored in the second memory means. The 2nd “1st 1st i0
Partial data of the η image data is processed according to the data conversion mode 4-30 according to its image processing mode. The present invention is characterized in that it includes an image data processing section for outputting Iji image data to an image output section. ``Secondly, in a preferred embodiment of the image processing apparatus of the present invention, the image output section in the image processing apparatus includes:
It is used as a mimeograph printing machine with an automatic plate-making function, which is equipped with a plate-making machine section having a thermal press, and a printing machine section that winds the plate formed by the plate-making machine section around a plate cylinder and performs mimeograph printing on the plate cylinder. You can.

[Operation] The image processing method and image processing apparatus according to the present invention use image data with two levels of resolution when performing image processing. One is high-resolution first image data and third image data, and the other is low-resolution second image data. 3. The second image data specifies the image processing target area for the original image. This is so-called working image data for obtaining a monitor image used when reading a document, and preferably has a lower resolution than the resolution of the first image data as document reading data. Image - (Use - to effectively specify the image processing target area.
ILI-Ii image data is high-resolution image data for both original image input and processed image output before and after image processing, and low-resolution image data is used as the image data for actual image processing. A high-resolution first image corresponding to the image processing area specified as the standard
The image data (original read data) within the area is converted into data according to various image processing modes and output as third image data. Therefore, the first memory means for storing the second image data of the monitor image for specifying the area to be image processed can have a minimum capacity. a document reading operation of taking the first image data of L1 once to obtain the second image data for specifying the image processing target area;
The original reading operation to obtain the first image data for the second time in order to perform actual image processing is performed by one original input means, so the original that has been input to the original input means to obtain the first image data is , the original is left as it is until HiIII image processing (editing) is completed, and the set position of the original does not change. This means that when a processing area is specified, areas other than that area become non-processing areas, and the distinction between both areas is stored. Therefore, as an input operation, it is sufficient to specify either the processing area or the non-processing area, but the entire data of the first image data is handled as the processing target data, and the partial data within the processing area At the same time, data is converted according to the image processing mode, and at the same time, partial data (J data) in the non-processing area is processed as is without data conversion.

Effects of the Invention As is clear from the above explanation, according to the present invention, the following excellent effects are achieved. On the other hand, it becomes unnecessary to adjust the position of the original document to the above-mentioned initial position when reading the original image in the actual image processing operation. In addition, there is no positional deviation between the corresponding original read data within the specified image processing target area and the original read data which is the image data to be actually processed. Furthermore, if the image data (second image data) for specifying the area to be image processed is stored, the capacity of the memory means should be made as small as possible.

For reading, a positioning operation is performed, and the document positions match in both cases.In other words, the position is equivalent to the image processing area specified on the monitor image, or it matches the image processing target area of the actual document. Incidentally, in this embodiment (the J first memory 8 and the second memo January 1 are configured separately, it would be sufficient if they were memory means with different functions, so I guess I did).
