==IMAGE-FORMING APPARATUS, CORRECTION CHART, AND METHOD - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18458430 titled 'IMAGE-FORMING APPARATUS, CORRECTION CHART, AND METHOD

==Simplified Explanation==

The patent application describes an image-forming apparatus that corrects unevenness in light amount of an exposure head using a correction chart.

* Generating unit generates correction data for correcting light amount unevenness using a read image of a correction chart.
* Correction unit corrects image data for image formation based on the correction data.
* Exposure head includes light-emitting chips with light-emitting elements.
* Correction chart has regions, first and second reference marks, and partial regions determined based on positions of reference marks in the read image.
* Correction data is generated based on measurements on the partial regions.

### Potential Applications
* Printing industry for high-quality image formation.
* Medical imaging for accurate and precise image reproduction.

### Problems Solved
* Corrects unevenness in light amount for consistent image quality.
* Ensures accurate image reproduction for various applications.

### Benefits
* Improved image quality.
* Consistent and precise image reproduction.
* Enhanced performance of image-forming apparatus.


==Original Abstract Submitted==

An image-forming apparatus includes a generating unit that generates correction data for correcting an unevenness in light amount of an exposure head using a read image of a correction chart, and a correction unit that corrects image data for image formation based on the correction data. The exposure head includes light-emitting chips each of which includes light-emitting elements. The correction chart includes a plurality of regions arranged in a direction, a first reference mark located on one side of the regions, and a second reference mark located on the other side of the regions. The generating unit determines partial regions respectively formed by the light-emitting chips within the regions based on positions of the first and second reference marks in the read image of the correction chart, and generate the correction data based on a result of measurement on the partial regions.
