Gaze-Stabilized Image Regions for Focus and Exposure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices lack efficient methods to dynamically set regions of interest based on user gaze for optimal image processing and focus adjustment.
Innovation Solution
An information processing apparatus and method that detects and sets regions on an image based on the stability of the user's visual line position over time, using gaze positions to define rectangular, circular, or closed regions, and adjusts focus on target subjects within these regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If region setting is based on simple visual line position, then responsiveness is improved, but precision of region setting deteriorates
Solution Approach 1:
The system performs preliminary stabilization judgment on visual line positions before final region setting. By pre-filtering unstable gaze positions through stabilization judgment using predetermined thresholds for position variation and time duration, the system ensures that only stable gaze positions contribute to region setting, thereby maintaining both responsiveness and precision.
2Measurement precision
If region setting uses multiple gaze positions, then region accuracy is improved, but processing complexity increases
Solution Approach 1:
The system segments the gaze position data processing into distinct stages: visual line position detection, stabilization judgment (filtering), and region setting. By dividing the processing into these modular segments with clear boundaries and criteria, the system manages complexity while achieving accurate region setting based on multiple stabilized gaze positions.
Solution Approach 2:
The system dynamically adjusts region settings based on the number and distribution of stabilized gaze positions. The region setting unit flexibly determines appropriate regions by considering the temporal and spatial characteristics of multiple gaze positions, adapting the region boundaries dynamically rather than using fixed algorithms.

AI summary
An information processing apparatus is an information processing apparatus including a processor, the processor is configured to acquire first image data, output the first image data to a display, acquire visual line data, detect, as a gaze position, a visual line position of a case where a state where a variation distance of the visual line position with respect to a first image indicated by the first image data is equal to or shorter than a first distance continues for a first time or longer based on the visual line data, and set a first region based on two or more gaze positions.
