[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a copying machine, a facsimile machine, and a printer. More specifically, it is provided with a plurality of image processing modes, and the processing state of the read original image in the processing mode is set in advance. The present invention relates to an image forming apparatus that can be confirmed and selected.

[0002]

2. Description of the Related Art In recent years, image forming apparatuses have been highly demanded for image quality, and therefore, various improvements have been made in quality improvement on the output apparatus side. Especially, if the original image is C
A photoelectric conversion unit such as a CD reads the image data as an electric signal, the signal is processed by various image processing units, and then a writing unit such as a laser converts the signal into an optical signal corresponding to the image data. 2. Description of the Related Art There is a so-called digital copying machine, which is an image forming apparatus that forms an image on a sheet and finally executes a copying process of a document image. In this digital copying machine, a read image of a document is passed through an image processing means to improve image quality of the image of the document, or
It has become easier to obtain an image that has undergone image editing processing that is different from the state of the original.

The above-mentioned image quality improvement processing includes, for example, the following. That is, first, when the background of the document is dirty, the background is removed and the contrast is improved and output. Secondly, if the line portion of the document is thin and weak, the line thickness is made thick and output as a strong image. Thirdly, when the density of the original is low, the density is increased and the image is output as a sharp image. Fourth, when the original is a halftone with gradation and the halftone is expressed and output as a halftone dot image, the image of the output image is output differently depending on the fineness (number of lines) of the halftone dot. To do. Fifth, by executing the image editing process, a wide variety of images that have been edited and processed (hollowing out, black and white reversal, halftone, halftone, italic, mirror, etc.) are output.

Further, in order to meet the above demands, specifically, the following image forming apparatus is known as an image forming apparatus which forms an image by selecting the image output conditions described above. . That is, firstly, a device for displaying the result of selective setting (factory setting, serviceman setting, etc.) of a plurality of values of the state of the apparatus (for example, charging current, developing bias value, exposure energy, etc.) relating to the image forming conditions. , Or a device that prints out its display contents using the internal memory. Secondly, control status (setting conditions) and usage status (number of sheets used, mode classification result, jam occurrence location) of devices such as printers and facsimiles. And its frequency) are displayed or printed out.

Third, in order to confirm the quality of the finished image in advance, a judgment image pattern (for example, resolution,
A device for storing a chart for comprehensive evaluation of gradation, fine line reproducibility, etc. in the internal memory and printing out by a service person or sales person or user when necessary. Fourth, reading original image , A digital copying machine that performs signal processing as an electric signal and edits and processes the image data and then outputs the image data. Fifthly, the image data is read as an electric signal, the image data is stored by a storage unit, and then the image is output. There is a digital copier with a memory function.

[0006]

However, in the conventional image forming apparatus as shown above, since the setting state of the image output apparatus is the value of the characteristic parameter,
It is not possible to know what kind of image quality the state will be without checking the output results, so it is necessary to repeat trial and error operations, take more time than necessary, and rely on the operator's know-how. Therefore, there is a problem in that the image quality varies among the devices.

The state of the image quality can be confirmed by outputting the internally generated pattern and checking the output result. However, when a plurality of image processing modes are provided, the image pattern is output for each mode. Need to do. That is, there is a limit to storing the judgment image pattern in the internal memory, and there is a problem that it cannot be applied to all images. Further, when the internally generated pattern is different from the original image, there is a problem that it is not possible to directly check how the original image is output.

The present invention has been made in view of the above, and in the case of copying an original image, it corresponds to the original image before the final image is output after performing the image quality improving process and the editing process. The purpose is to improve the operability of setting the parameters related to the image quality by making it possible to check the image quality.

The operability in setting the parameters relating to image quality is improved.

Further, in the image forming apparatus according to the present invention (claim 7), the image signal processing control means has an unprocessed mode or a standard processing mode, a line thickness changing processing mode, an image density changing processing mode, a character changing processing. Since a plurality of processing modes of modes are prepared, the processing level for the read image can be secured and appropriate processing can be handled.
