Camera Eye Selection Indicators for Accurate Focus Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera systems face challenges in improving focusing accuracy, particularly when detecting and tracking eyes and faces, as they often fail to efficiently switch focus between multiple detected eyes or faces, leading to suboptimal image capture.
Innovation Solution
The system includes a detection unit for eyes and faces, a selection unit to choose a specific eye or face, and a display unit to indicate the selected feature, allowing users to switch focus manually and providing visual cues for alternative detection targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera automatically detects and focuses on eyes and faces, then focusing accuracy is improved, but the user cannot manually switch between multiple detected eyes or faces
Solution Approach 1:
The camera system automatically detects multiple eyes and faces, then self-services by displaying indicators for each detected feature. The system enables manual switching by showing all detected features with selectable indicators, allowing the user to choose which eye or face to focus on without requiring complex manual detection or search operations.
2Loss of information
If the camera displays indicators for all detected eyes and faces, then user awareness of detection targets is improved, but display complexity increases
Solution Approach 1:
The display system segments the information by providing distinct visual indicators for different types of detected features (eyes versus faces). Each detected eye receives an eye indicator, and each detected face receives a face indicator, allowing users to clearly distinguish between different detection targets and their types without confusion.
Solution Approach 2:
Different visual characteristics are applied to different indicators based on their local context - eye indicators are displayed with characteristics suitable for eye detection, while face indicators use different characteristics appropriate for face detection. This local differentiation helps users quickly identify and select the desired focus target.
3Adaptability or versatility
If the camera provides both eye and face detection indicators, then detection versatility is improved, but the selection process becomes more complex
Solution Approach 1:
The system dynamically adapts the detection and display based on what is found in the scene. When both eyes and faces are detected, the system provides both types of indicators; when only one type is detected, only that type's indicators are shown. This dynamic behavior maintains versatility while simplifying the selection process by not overwhelming the user with unnecessary indicator types.

AI summary
An electronic apparatus includes a detection unit that detects eyes from an image, a selection unit that selects one eye from the eyes detected by the detection unit, an operation unit that accepts an operation of causing the selection unit to select an eye different from the selected eye, and a display unit that displays an indication superimposed on an image indicating that the eye is selected by the selection unit.
