Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in finding and utilizing desired images from large collections due to the inclusion of defective images, such as those taken with shaking, which affect the quality of layout images created and user satisfaction.
Innovation Solution
An image processing apparatus and method that acquires an image group, creates layout candidates, and evaluates them based on image quality and size, allowing for the filtering out of defective images and the generation of user-preferred layouts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If defective images are included in the layout to maximize image utilization, then the quantity of images used increases, but the quality and user satisfaction of the layout decreases
Solution Approach 1:
The patent changes the evaluation parameters by introducing a composite scoring system that combines image quality metrics (sharpness, exposure, composition) with layout suitability metrics (size matching, positional arrangement, thematic coherence). This allows defective images to be evaluated on multiple dimensions, enabling their inclusion in layouts when they meet acceptable thresholds in certain aspects while compensating for deficiencies in others.
Solution Approach 2:
The system dynamically adjusts the selection criteria based on the specific characteristics of each image and the requirements of different layout positions. Instead of applying fixed quality thresholds, the evaluation adapts to determine whether a defective image can be appropriately placed in specific positions where its defects are less noticeable or where its strengths can be leveraged.
2Manufacturing precision
If strict quality filtering is applied to exclude defective images, then the quality and user satisfaction of layouts improves, but the number of usable images decreases
Solution Approach 1:
The patent transforms the binary accept/reject quality filter into a multi-dimensional scoring system. Instead of discarding images below a certain quality threshold, the system assigns numerical scores across multiple parameters (sharpness, exposure, composition, color balance) and combines these with layout-specific requirements to determine optimal image placement, thereby utilizing more images with varying quality levels.
Solution Approach 2:
The evaluation system applies different quality standards to different regions and positions within the layout. Certain positions may tolerate more defects than others, and the system matches images to positions based on local requirements rather than applying uniform quality criteria across the entire layout.
3Device complexity
If image quality evaluation is performed without considering layout size, then the evaluation process is simpler, but the accuracy of layout suitability assessment decreases
Solution Approach 1:
The patent merges image quality evaluation with layout size assessment into a unified scoring mechanism. The evaluation simultaneously considers intrinsic image qualities (sharpness, exposure) and extrinsic factors (image size relative to layout slot, scaling requirements, aspect ratio matching), combining these into a composite suitability score that determines optimal placement.
Solution Approach 2:
The system introduces size-related parameters (scaling factor, aspect ratio deviation, area utilization) into the evaluation function and dynamically weights them based on layout requirements. This transforms the evaluation from a static quality check to a dynamic assessment that adapts to the specific dimensional constraints and design goals of each layout configuration.

AI summary
An image group including at least one image is acquired, a layout candidate is created, by laying out images included in an acquired image group, and the created layout candidate is evaluated. Evaluation of the layout candidate is performed based on evaluation of each image laid out within a layout, and a scaling factor based on image size of the image placed in the layout, and a size of the image.
