Thumbnail Image Generation Using Object Coordinates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for generating thumbnail images in electronic devices often result in unsuitable images due to improper resizing and cropping, making it difficult for users to view original images effectively.
Innovation Solution
A method and device that set coordinates for objects within images, such as person and place information, to generate thumbnail images, utilizing focus information, facial recognition, and geotagging, allowing for accurate extraction and storage of relevant image areas as thumbnail data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the original image is reduced and cropped to fit thumbnail size, then the thumbnail image size is suitable for display, but the thumbnail image may not be suitable for viewing the original image
Solution Approach 1:
The patent segments the original image into multiple candidate thumbnail images by dividing it into different regions (e.g., top-left, top-right, bottom-left, bottom-right quadrants). Each segment is evaluated based on focus information to determine which region contains the most important content, ensuring the selected thumbnail maintains viewing quality while fitting the display size requirement.
2Loss of information
If focus information is used to generate thumbnail image, then the thumbnail may represent important content, but the thumbnail image may not be suitable for viewing the original image
Solution Approach 1:
The patent applies local quality by using focus information to identify specific regions within the original image that contain important content (such as faces or focused areas). The thumbnail generation process then prioritizes these local regions, ensuring that the most important content is preserved in the thumbnail while adapting to the size constraints.
3Area of stationary object
If the original image is adjusted to fit thumbnail size without considering image portions, then the thumbnail size is suitable, but the thumbnail image may not be suitable for viewing the original image
Solution Approach 1:
The patent performs preliminary action by analyzing the original image before generating the thumbnail. It pre-identifies important regions using focus information and determines the optimal cropping area in advance. This preliminary analysis ensures that when the image is resized to fit thumbnail dimensions, the most relevant content is preserved rather than lost.
