image forming device

Abstract

An image forming apparatus includes a document reading unit, an image forming unit, an image data saving unit, a correction instruction detection unit, an image correction unit, and a controller. The document reading unit reads an image on a source document and acquires image data. The image forming unit prints an image on a recording sheet according to the image data. The image data saving unit saves the image data of image printed by the image forming unit on the recording sheet. The correction instruction detection unit detects the correction instruction written on the recording sheet on which the image is printed. The image correction unit corrects the image data stored in the image data saving unit, according to the correction instruction detected by the detection unit. The controller causes the image forming unit to print an image representing the image data corrected by the image correction unit.

Description

technical field [0001] The present invention relates to an image forming apparatus, and particularly relates to a technique for correcting an image to be printed. Background technique [0002] When an image forming apparatus prints, for example, when copying a paper that has been written by many people, or when multiple sheets of paper on which information is written are attached to a single paper, there may be a situation. On the other hand, in the case of copying the produced items, since the strength of each pen and the size of the characters are not the same, the density and size of the printed matter may vary, and the overall balance of the printed matter may deteriorate. For example, text with a light stroke will be printed lightly, while text with a heavy stroke will be printed thick. [0003] In this case, there is a method of adjusting the print density so that characters with a light pen stroke are printed darker. However, since the print density is set for the en...

Problems solved by technology

However, in this technique, when reprinting is performed by correcting the setting content of printing, the correction operation needs to be re-set in detail as in the past.

[0007] In these techniques, there is a problem that the originality of the manuscript is lost, and it is not possible to easily perform an image correction instruction.

In addition, it is impossible to eliminate the quality variation in each part of the printed image that tends to occur in printed matter such as paper with many people's scribbles
