Image Processing Apparatus Partitioning Document Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional copiers produce documents with inner and outer ring images of differing qualities due to multiple generations of copying, leading to mismatched and blurry or unclear images.
Innovation Solution
An image processing apparatus and method that separates document images into first and second area images, performs enhancement on the first area image, and encodes the second area image for recognition, allowing for calibrated printing to maintain image quality across generations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional copiers perform multiple generations of copying processes, then the copying function is achieved, but the inner ring image and outer ring image have different qualities with mismatched appearance
Solution Approach 1:
The patent divides the document image into two distinct areas: the first area containing the original content and the second area containing the encoded history records. By segmenting the image processing into separate enhancement and encoding operations for each area, the system maintains different processing qualities for different regions, resolving the contradiction between productivity and image quality consistency.
Solution Approach 2:
The patent applies different image processing operations to different areas of the document. The first area image undergoes enhancement processing to improve clarity, while the second area image undergoes encoding processing to create history records. This local differentiation of processing quality allows each region to have optimal characteristics for its specific function.
2Productivity
If multiple generations of copying processes are performed, then copying productivity increases, but the first area image becomes blurry or unclear
Solution Approach 1:
The patent performs enhancement processing on the first area image before it is used for subsequent copying operations. By pre-enhancing the image quality and correcting degradations before they propagate to the next generation, the system maintains image clarity across multiple copying generations while preserving productivity.
Solution Approach 2:
The system encodes history records in the second area that track copying generations and image quality metrics. This feedback mechanism allows the system to monitor degradation across generations and apply appropriate enhancement processing to maintain first area image clarity throughout the copying process.

AI summary
An image processing apparatus includes an image processing device. The image processing device includes a receiving port and a processor connected together. The receiving port receives old image data corresponding to a document image of a document. The processor divides the old image data into first area image data corresponding to a first area image of the document, and second area image data corresponding to a second area image of the document, and further performs image enhancement processing on the first area image data to obtain enhanced first area image data. Thus, the first area image may be separated from the second area image, and the image enhancement processing is performed on the first area image. The enhanced first area image data and the second area image data are separately outputted or combined for output.
