Solution Overview

Problem

Conventional electronic devices often cut off unwanted areas of images when generating thumbnail images, leading to suboptimal display without additional editing processes, as the size and aspect ratio of thumbnails are not optimized based on metadata and object information.

Innovation Solution

A method and apparatus that detect metadata and object information to determine the aspect ratio of thumbnail images, ensuring that a representative area is fully displayed within the device's window by adjusting the image size accordingly, prioritizing object information over metadata when necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the thumbnail image is resized or cropped according to the size of the window provided by the application, then the thumbnail image can be displayed in the application window, but the area not desired by a user may be cut off

Engineering Contradiction:
Improvethumbnail image display adaptabilityVSAvoidimage content loss
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent performs preliminary detection of metadata and object information (such as face locations, important regions) before generating the thumbnail image. Based on this preliminary analysis, the system pre-determines the optimal aspect ratio and cropping region that preserves important content while adapting to the display window, thus preventing information loss before it occurs

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent dynamically changes the aspect ratio parameter of the thumbnail image based on the detected object information and metadata. Instead of using a fixed aspect ratio, the system adjusts the aspect ratio parameter according to the important regions identified in the image, allowing the thumbnail to adapt to different display windows while preserving critical content

Inventive Principle:
Principle #35Parameter changes

2Productivity

If the thumbnail image is generated without additional image editing process, then the generation process is simple and fast, but the image may not be optimized for the user

Engineering Contradiction:
Improvethumbnail generation speedVSAvoidimage optimization quality
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent enables the thumbnail generation system to automatically detect and analyze image metadata and object information, then self-determine the optimal aspect ratio and cropping parameters without requiring manual user intervention or additional editing processes. The system serves itself by using its own detection capabilities to optimize the thumbnail generation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent performs preliminary detection of metadata and object information before thumbnail generation, allowing the system to pre-calculate the optimal aspect ratio and cropping region. This preliminary analysis enables the system to generate optimized thumbnails automatically without requiring subsequent manual editing or additional processing steps

Inventive Principle:
Principle #10Preliminary action
