Image Processing Device for Automatic Composition Frame Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in designating suitable composition frames for image cropping, often resulting in low-quality frames with poor composition balance, partial cutting out, or insufficient pixels, especially in low-budget video production using UHD imaging.
Innovation Solution
An image processing device and method that includes an evaluation unit to assess the quality of a captured image region and a composition frame setting unit to automatically set a suitable composition frame based on the evaluation results, ensuring optimal cropping with reduced user effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a user manually designates a region for cutting out, then the user has control over the composition frame selection, but the user effort increases and the quality may be insufficient
Solution Approach 1:
The system performs automatic evaluation and selection of composition frames using the evaluation unit and composition frame setting unit, eliminating the need for manual user designation. The device serves itself by automatically assessing quality conditions and selecting optimal regions without human intervention.
Solution Approach 2:
The manual mechanical process of user designation is replaced with an automated electronic evaluation system. The evaluation unit uses computational algorithms to assess quality conditions, substituting the mechanical action of manual region selection with an automated digital evaluation and selection process.
2Measurement precision
If multiple imaging devices are used to capture images, then the image quality and composition variety improve, but the cost and complexity of video production increase
Solution Approach 1:
The system segments a single high-resolution UHD image into multiple composition frames, each suitable for different purposes. The evaluation unit divides the image evaluation task across multiple candidate regions, and the composition frame setting unit creates multiple usable frames from one captured image, replacing the need for multiple imaging devices.
Solution Approach 2:
A single imaging device captures UHD images that can be universally used to generate multiple HD images through automatic composition frame setting. The system makes one imaging device perform the work of multiple devices by automatically creating various composition frames from a single high-resolution capture.
