Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face challenges in capturing clear images in dark environments due to increased noise when sensitivity is enhanced, leading to poor imaging effects.
Innovation Solution
An imaging method and system that control a gimbal-mounted imaging device to enter a stabilization mode when incident light is low, allowing for a longer exposure duration to capture images, thereby reducing noise and maintaining image quality without increasing sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If sensitivity is increased to improve imaging in dark environments, then the amount of captured light is improved, but noise increases causing poor imaging effect
Solution Approach 1:
The patent dynamically adjusts the exposure duration based on the detected light intensity. When light intensity is low, the exposure duration is extended to capture more light without increasing sensitivity, thereby avoiding noise amplification. This dynamic parameter adjustment resolves the contradiction by adapting the imaging parameters to environmental conditions rather than using a fixed high-sensitivity setting.
2Illumination intensity
If exposure duration is extended to capture more light, then imaging quality in dark environments is improved, but image stability deteriorates due to motion blur
Solution Approach 1:
The patent introduces a gimbal stabilization system as an intermediary mechanism to counteract camera motion during extended exposure. The gimbal actively stabilizes the camera position, allowing the imaging device to maintain stability even with longer exposure durations. This mediator enables the system to achieve both extended light capture and image stability simultaneously.
3Stability of the object's composition
If a tripod is used to improve image stability during long exposure, then image quality is improved, but device portability and ease of operation deteriorate
Solution Approach 1:
The patent implements self-service stabilization through an active gimbal system that automatically compensates for camera motion without requiring external support devices like tripods. The gimbal's motorized stabilization mechanism actively counteracts hand movements and external vibrations, enabling the system to maintain stability while remaining portable and easy to operate. This self-stabilizing capability eliminates the need for additional support equipment.
