Image Processing Apparatus Change Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to determine which areas of an image are affected more significantly by image processing, especially when the output device has different characteristics than the display device, such as a printer, making it hard to visualize the changes in tonality and other image qualities.
Innovation Solution
An information processing apparatus that performs image processing based on the output device's characteristics and displays information on the display device, showing the magnitude of change in different areas of the image by analyzing the image before and after processing, using relative or absolute measurement methods to indicate the relationship between changes in various areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image processing is performed based on output device characteristics, then the image quality for printing is improved, but the user cannot clearly understand which areas change more greatly
Solution Approach 1:
The image is divided into multiple areas, and the amount of change is calculated and displayed for each area separately. This segmentation allows users to understand which specific regions are affected more significantly by the image processing, resolving the contradiction between performing accurate image processing and maintaining visibility of change information.
2Reliability
If the display device and output device have different characteristics, then the output quality is optimized for the specific device, but the user cannot figure out how the image output is changed
Solution Approach 1:
A measurement result image is introduced as an intermediary representation that visually encodes the amount of change in each area. This intermediary allows users to detect and measure changes without being limited by the different characteristics between display and output devices, while maintaining optimized output quality.
3Manufacturing precision
If image processing is applied to improve output characteristics, then the printed image quality is enhanced, but the user loses ability to compare original and processed areas
Solution Approach 1:
The measurement result image uses color variations (luminance or color saturation) to represent different amounts of change in each area. This visual encoding preserves comparison information between original and processed areas while allowing the image processing to enhance print quality, as the change information is represented through visual properties rather than direct pixel comparison.

AI summary
An information processing apparatus is provided to facilitate a user's understanding of which area of an image has a higher degree of change when image processing is performed on the image. The information processing apparatus displays, on a display device, information indicating a relationship in magnitude between a first amount of change by the image processing in a first area included in a predetermined image and a second amount of change by the image processing in a second area included in the predetermined image.
