Camera Mode Control via Sensor Fusion and Confidence Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera systems lack the ability to automatically switch operation modes in real-time to optimize image or video capture during user activities, such as skiing or surfing, where manual mode selection is impractical due to the user's focus on the activity.
Innovation Solution
The camera system uses auxiliary sensor data and image analysis to determine confidence values for switching between initial and alternative operation modes, such as burst image capture or high frame rate video, ensuring optimal capture settings based on detected events like motion or location changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual mode selection is used, then user control over capture settings is maintained, but the ability to optimize capture during activities is lost
Solution Approach 1:
The camera system automatically detects events through sensors and image analysis, then autonomously switches between capture modes without requiring user intervention. The system serves itself by making intelligent decisions about when to use burst mode, high frame rate video, or standard capture based on detected motion, orientation changes, and other environmental cues.
Solution Approach 2:
The camera dynamically adjusts its operation mode in real-time based on changing conditions. The system transitions between different capture modes (still image, burst, video, high frame rate video) depending on the current activity state, making the capture settings adaptive rather than static.
2Productivity
If automatic mode switching is implemented, then capture optimization during activities is achieved, but system complexity increases
Solution Approach 1:
The automatic mode switching system is divided into separate functional modules: sensor data acquisition, image quality analysis, event detection logic, and mode execution. Each component handles a specific aspect of the decision-making process, making the overall complex system manageable through functional segmentation.
Solution Approach 2:
The system uses intermediate analysis of image quality metrics and sensor data as a mediator between raw environmental conditions and capture mode selection. Rather than directly responding to all possible inputs, the system processes these through intermediate evaluation stages that simplify the decision-making architecture.
3Adaptability or versatility
If multiple capture modes are available, then capture versatility is improved, but ease of operation deteriorates
Solution Approach 1:
The camera system automatically selects the appropriate capture mode from multiple available options based on detected events and environmental conditions. Users benefit from the versatility of multiple modes without needing to manually select between them, as the system performs the selection autonomously.
Solution Approach 2:
The system changes operational parameters (frame rate, burst duration, capture interval) dynamically based on the detected activity state. This allows the camera to adapt its capture characteristics to match the situation without requiring users to understand or select from multiple mode options.

AI summary
Cameras may monitor its operation and automatically switch between operation modes thereby to best capture users' experiences. Auxiliary sensor data collected by the one or more sensors and/or captured image data may be analyzed to determine when a camera should switch to a different operation mode. The auxiliary sensor data and/or the content of the captured images may include motion information indicating whether the camera or the captured scene has relatively high-motion, relatively low-motion, or no motion. Event(s) may be detected by analyzing the auxiliary sensor data and/or analyzing captured image data, and preferred operation mode(s) suitable for capturing the events can be determined. Each preferred operation mode may be associated with a confidence value. A camera may switch to a preferred operation mode for capturing an event if the event is determined with high confidence to take place at a time point.
