Arbitrary Reference Image Positioning for Color Misregistration Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face limitations in adjusting the position of a reference image on a recording medium, requiring the reference image to be formed at the leading end of a page for correcting color misregistration, which restricts the flexibility in positioning the reference image.
Innovation Solution
An image processing apparatus that allows setting the image position of a reference image arbitrarily on a specific page and uses this reference image to adjust the positions of other images on adjacent pages, reducing the need for the reference image to be at the leading end of the page.

Engineering Contradiction Analysis
1Manufacturing precision
If the reference image is formed at the leading end of a page for correcting color misregistration, then color misregistration can be corrected, but the flexibility in positioning the reference image is restricted
Solution Approach 1:
The patent applies dynamics by making the reference image position adjustable rather than fixed. The system allows the reference image to be positioned at arbitrary locations on the recording medium, transforming a static positioning constraint into a dynamic adjustable parameter. This enables flexible adaptation to different layout requirements while maintaining color misregistration correction capability.
Solution Approach 2:
The patent changes the parameter of reference image position from a fixed constraint (leading end of page) to a variable parameter that can be arbitrarily set. By allowing the position parameter to be changed freely within the recording medium area, the system achieves both accurate color misregistration correction and positioning flexibility.
2Device complexity
If the reference image position is fixed at the leading end of the page, then the image position adjustment process is simplified, but the adaptability to different page layouts is reduced
Solution Approach 1:
The patent applies universality by enabling the reference image to serve multiple positioning functions across different page layouts. The same reference image mechanism can adapt to various layout configurations (different positions, orientations, and arrangements) without requiring separate adjustment processes for each layout type, thus achieving both simplicity and adaptability.
Solution Approach 2:
The system transforms the fixed reference position into a dynamic adjustable parameter, allowing the reference image to be positioned according to specific page layout requirements. This dynamic positioning capability maintains process simplicity while significantly improving adaptability to different layouts.
3Ease of manufacture
If the reference image must be on the same page as the image to be corrected, then the correction process is straightforward, but the ability to use reference images from different pages is limited
Solution Approach 1:
The patent applies dimensionality change by extending the reference image selection from the same page (two-dimensional constraint) to different pages (adding a third dimension - page index). The system allows reference images to be selected from any page in the recording medium, creating a three-dimensional search space for optimal reference image selection while maintaining straightforward correction processing.
Data Source
AI summary
An image processing apparatus includes a processor. The processor is configured to set an image position of a reference image in a transport direction of a recording medium to an arbitrary position on a specific page of the recording medium. The reference image is formed using a first color and serves as a reference for an image position of an image of a second color to be formed after the image of the first color is formed. The processor is also configured to adjust the image position for the second color on an adjacent page, located adjacently upstream of the specific page in the transport direction, by using image information of the reference image formed on the specific page.
