Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capture devices lack the ability to seamlessly transition between image and video capture modes based on audibly detectable events, and they do not efficiently process and transfer high-resolution images, leading to suboptimal user experience and storage management.
Innovation Solution
A capture device configured with multiple capture modes, including an image capture mode and a video capture mode, that automatically transitions between modes based on detected events, and generates low-resolution images for rapid processing and decision-making, allowing for efficient transfer and analysis of high-resolution content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the capture device continuously captures high-resolution video, then video quality is improved, but storage space and energy consumption increase significantly
Solution Approach 1:
The system dynamically changes the resolution parameter of video capture based on detected event significance. During normal operation, lower resolution is used to conserve storage and energy. When an audibly detectable event occurs, the system transitions to high-resolution video capture, thus achieving high video quality only when necessary while reducing overall storage requirements.
Solution Approach 2:
The capture device transitions between different capture modes (image mode and video mode) and different resolution levels based on detected events. This dynamic adjustment allows the system to optimize between video quality and storage consumption by capturing high-resolution video only during significant events rather than continuously.
2Loss of information
If the capture device captures both high-resolution images and video continuously, then documentation completeness is improved, but storage space and processing time increase
Solution Approach 1:
The system changes the capture mode parameter based on event detection. During normal periods, it captures only periodic images. When an audibly detectable event is detected, it switches to video capture mode to document the event comprehensively. This ensures complete documentation of significant events while avoiding unnecessary storage of redundant data during normal operation.
Solution Approach 2:
Instead of continuously capturing both images and video, the system applies partial action by capturing only images during normal operation and adding video capture only when events occur. This selective approach maintains documentation completeness for significant events while reducing overall storage requirements.
3Loss of information
If the device transfers high-resolution images immediately, then data availability is improved, but transfer time and energy consumption increase
Solution Approach 1:
The system performs preliminary action by first transferring a low-resolution version of the image before transferring the full high-resolution image. This allows the user to quickly access and preview the image content without waiting for the complete high-resolution file transfer, thus improving data availability perception while reducing initial transfer time.
Solution Approach 2:
The image transfer process is segmented into two stages: first transferring a low-resolution preview version for immediate availability, then transferring the complete high-resolution version. This segmentation allows the system to provide quick access to image data while ultimately delivering full-quality images, balancing data availability with transfer time requirements.
4Difficulty of detecting and measuring
If the capture device operates in video capture mode continuously, then event detection capability is improved, but energy consumption increases
Solution Approach 1:
The system uses periodic action by capturing images at regular intervals during normal operation, which consumes minimal energy. When an audibly detectable event occurs, it switches to continuous video capture mode to fully document the event. This periodic imaging combined with event-triggered video capture maintains event detection capability while significantly reducing energy consumption compared to continuous video recording.
Solution Approach 2:
The capture device dynamically switches between low-power image capture mode and high-power video capture mode based on detected events. This dynamic operation allows the system to maintain event detection capability by being ready to switch modes while minimizing energy consumption by spending most time in the lower-power image capture mode.

AI summary
Various embodiments provide a capture device, e.g., a camera, that is configured to have multiple capture modes including an image capture mode and a video capture mode. The capture device can be set to the image capture mode in which images or photos are periodically, automatically captured. Upon detection of a particular event, such as an audibly detectable event, the capture device automatically triggers the video capture mode and begins to capture video. After a period of time, the capture device can transition back to the image capture mode. Transition to the image capture mode can occur in various ways, e.g., after passage of a period of time, after the audibly detectable event terminates or attenuates, by way of user input and the like. In some embodiments, the capture device can be embodied as a wearable camera that is worn by a user.
