Pupil Focus Display Control for Multi-Eye Depth-of-Field Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pupil autofocus systems fail to provide suitable display indicating whether both pupils can be included in the depth of field, making it difficult for users to select appropriate focus settings when capturing images of multiple pupils.
Innovation Solution
A display control apparatus and method that includes an acquisition unit, focus detection unit, and display control unit to determine if multiple pupils can be included in a specific depth, displaying different indexes for pupils within and outside the depth of field.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pupil autofocus is used to focus on one pupil, then the focusing function is simple and reliable, but the ability to focus on both pupils simultaneously is lost and user awareness of focus state is insufficient
Solution Approach 1:
The display screen is segmented into multiple display regions, with each region corresponding to a specific pupil. The focus detection results for each pupil are independently displayed in their respective regions, allowing users to see the focus state of each pupil separately. This segmentation enables comprehensive focus information display while maintaining reliable individual pupil focus detection.
2Reliability
If depth control is performed to include both pupils in depth of field, then both pupils can be in focus, but suitable display indication of focus state is not provided
Solution Approach 1:
Different colors are used to indicate different focus states in the display regions. When a pupil is in focus, its corresponding display region shows a specific color (e.g., green); when out of focus, it shows a different color (e.g., red). This color-coded visual feedback system provides intuitive focus state information, enabling users to understand whether both pupils are in focus without complex indicators.
3Device complexity
If no specific display indication is provided for pupil focus state, then the device complexity is low, but user ability to select appropriate focus settings is reduced
Solution Approach 1:
The system provides real-time feedback by displaying focus detection results in dedicated regions corresponding to each pupil. Users can immediately see whether each pupil is in focus or out of focus, enabling informed decisions about focus settings. This feedback mechanism enhances ease of operation without requiring complex additional hardware.

AI summary
The control method includes determining whether a plurality of pupils can be included in a specific depth in a case where pupil information about the plurality of pupils of a same subject is acquired, and in a case where it is determined in the determining that the plurality of pupils of the same subject cannot be included in the specific depth, control is performed so that different indexes are displayed on a pupil within the specific depth and a pupil outside the specific depth.
