Wearable Camera Image Playback with Trigger Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for automatic photography in wearable cameras lack efficient methods to associate and display trigger conditions with automatically captured images, making it difficult for users to understand the context and conditions under which images were taken.
Innovation Solution
An image playback apparatus with an image acquisition device that captures photography information based on sensing results and trigger information, along with a display device that shows this information in association with the images, allowing users to easily understand the conditions under which each image was taken.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic photography is performed based on sensor measurements, then photography efficiency is improved, but user understanding of photographing context deteriorates
Solution Approach 1:
The system pre-associates trigger information (sensor data, timing, condition identifiers) with each automatically captured image at the moment of photography. This preliminary action ensures that context information is preserved and linked to the image before playback, allowing users to understand the circumstances under which each photo was taken without manual intervention.
2Loss of information
If trigger information is associated with automatically photographed images, then information completeness is improved, but device complexity increases
Solution Approach 1:
The image playback apparatus integrates multiple functions into a single system: it stores not only image data but also associated trigger information (sensor measurements, timing data, condition identifiers). The display controller universally handles both image rendering and trigger information presentation, eliminating the need for separate complex subsystems and managing increased information load through unified processing.
