Camera Mode Control for Rolling Shutter Artifact Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cameras lack an automatic mechanism to switch operation modes during activities, such as skiing or snowboarding, which prevents optimal image or video capture and inefficiently uses battery power due to manual mode selection limitations.
Innovation Solution
The camera system automatically switches between operation modes based on auxiliary sensor data, such as motion information, to determine when to switch to a high-motion mode with a shorter frame capture interval, minimizing distortion and battery drain.

Engineering Contradiction Analysis
1Use of energy by moving object
If the camera operates in a low-motion mode with a longer frame capture interval, then battery power is conserved, but image quality deteriorates during high-motion activities due to rolling shutter artifacts
Solution Approach 1:
The camera system dynamically switches between low-motion mode and high-motion mode based on detected motion levels. The frame capture interval is adjusted in real-time: longer intervals during low-motion periods to conserve battery, and shorter intervals during high-motion periods to minimize rolling shutter artifacts and maintain image quality.
Solution Approach 2:
The system changes the frame capture interval parameter based on motion detection. When motion exceeds a threshold, the camera transitions to high-motion mode with a shorter frame capture interval, directly addressing the image quality deterioration caused by rolling shutter artifacts during high-motion activities.
2Manufacturing precision
If the camera operates in a high-motion mode with a shorter frame capture interval, then image quality is maintained during high-motion activities, but battery power consumption increases
Solution Approach 1:
The camera employs dynamic mode switching that activates high-motion mode only when motion detection thresholds are exceeded. This ensures image quality is maintained during high-motion activities while avoiding unnecessary battery consumption during low-motion periods, as the system reverts to the more energy-efficient low-motion mode.
Solution Approach 2:
The frame capture interval parameter is selectively adjusted based on motion conditions. The system uses shorter intervals during high-motion periods to prevent rolling shutter artifacts, then returns to longer intervals during low-motion periods, optimizing the balance between image quality and battery power consumption.
3Manufacturing precision
If manual mode switching is required, then the user can optimize image capture settings, but the user cannot switch modes in time during high-motion activities and direct access to the camera is lost
Solution Approach 1:
The camera system performs self-service by automatically detecting motion levels and switching between operational modes without user intervention. The motion detection mechanism triggers automatic mode transitions, enabling the camera to optimize image capture settings during high-motion activities even when the user lacks direct access or is focused on the activity being recorded.
Solution Approach 2:
The system implements feedback through motion detection that continuously monitors camera movement and automatically adjusts operational modes accordingly. This feedback loop enables timely mode switching during high-motion activities, eliminating the need for manual user intervention while maintaining optimal image capture settings.

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 high-motion operation mode. The auxiliary sensor data include motion information of the camera and the content of the captured images include motion information of the captured objects. When a camera or objects captured by the camera are moving rapidly, the camera is switched to operate at the high-motion operation mode to ensure image quality and minimize artifacts to best capture users' experiences. Motion of the camera may be detected or predicted by analyzing the auxiliary sensor data and motion of the captured objects may be detected by analyzing the captured image data thereby to determine whether or not the camera should switch to the high-motion operation mode.
