Image Processing Apparatus Residual Rendering for Visual Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating an overlaid presentation of multiple images in a single output image are insufficiently intuitive, overwhelming viewers with excessive visual information and confusing differences between images, as they highlight both relevant and predictable differences.
Innovation Solution
An image processing apparatus that uses a first mapping function to render a first input image and a second mapping function to render a residual image, where the residual image represents prediction errors and is visually distinguished from the first input image, thereby highlighting only unpredictable information and reducing visual overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a color overlay method is used to combine multiple images in a single output image, then all visual information of each image is preserved and displayed, but the overlaid presentation becomes insufficiently intuitive and overwhelms viewers with excessive visual information
Solution Approach 1:
The patent segments the visual information by separating it into two distinct components: the original first image and a residual image representing prediction errors. This segmentation allows the output image to display all visual information while organizing it into distinguishable parts, with the residual image highlighting only unpredictable differences rather than overwhelming the viewer with undifferentiated overlay data
Solution Approach 2:
The patent applies color changes by rendering the residual image using a second mapping function that assigns specific colors to residual values. This color coding visually distinguishes the residual image from the first input image, making unpredictable information intuitively recognizable while preserving all original visual information
2Loss of information
If all differences between images are highlighted in the overlaid presentation, then complete information is provided, but predictable differences create visual clutter and reduce intuitiveness
Solution Approach 1:
The patent extracts only the unpredictable information from the second image by calculating prediction errors. The residual image contains only the differences that cannot be predicted from the first image, effectively taking out and highlighting only the relevant new information while eliminating visual clutter from predictable differences
Solution Approach 2:
The patent changes the parameter representation by using a second mapping function specifically for residual values, which is different from the first mapping function used for the original image. This parameter differentiation allows the system to preserve complete information while visually organizing it to reduce clutter, as viewers can easily distinguish between original and residual components
