Image Focus Area Classification Across Continuous Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems fail to effectively allow users to select and confirm the focus state of specific areas in captured images based on their intentions, particularly in cases where multiple images are taken continuously.
Innovation Solution
An image processing apparatus and electronic apparatus that includes an area setter, area detector, focus state acquirer, and classification processor to set and detect focus states in target areas across multiple captured images, allowing for classification and display of focus states based on user selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous imaging is performed to capture multiple images, then the probability of obtaining in-focus images increases, but it becomes difficult to confirm which specific area is in focus in each image
Solution Approach 1:
The patent segments the image into multiple focus determination areas (e.g., left eye area, right eye area, eyelash area) and independently determines focus states for each area. This allows the system to provide detailed focus information for specific regions while maintaining continuous imaging, resolving the contradiction between capturing multiple images and confirming focus areas.
2Area of stationary object
If the focus determination area is expanded to cover the entire image, then focus state can be assessed globally, but the user cannot selectively confirm focus state of specific areas of interest
Solution Approach 1:
The patent implements a dynamic focus determination system where the focus determination area can be flexibly set and adjusted by the user based on their intentions. The system adapts to different user needs by allowing selection of specific areas (e.g., eyes, eyelashes) while maintaining the ability to perform global focus assessment, thus resolving the contradiction between global coverage and selective adaptability.
3Loss of information
If multiple focus determination areas are analyzed simultaneously, then comprehensive focus information is obtained, but the complexity of focus state analysis increases
Solution Approach 1:
The patent divides the image into multiple independent focus determination areas and processes each area separately to determine focus states. This segmentation approach maintains comprehensive focus information while simplifying the analysis complexity by treating each area independently, avoiding the need for complex simultaneous multi-area analysis.
