Flash Lamp Position Adjusting Unit for Moving Object Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional electronic devices with cameras struggle to maintain effective flash lighting when objects move, as the flash lamp cannot automatically track the object, leading to inadequate light supplementation during photography in dark environments.
Innovation Solution
An electronic device with a flash lamp system that includes a position adjusting unit, a photosensitive unit, and a processing unit to detect object movement and adjust the flash lamp's position using a magnetic or motor-driven mechanism, allowing it to track the object and switch between near and far light modes based on brightness values, ensuring consistent illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the flash lamp is kept stationary, then the device structure is simple, but the flash lamp cannot track moving objects leading to inadequate light supplementation
Solution Approach 1:
The flash lamp is transformed from a stationary component to a dynamic one by introducing a position adjusting unit that enables it to move and track moving objects. The photosensitive unit detects object movement and sends signals to adjust the flash lamp's position in real-time, making the system adaptive to moving targets while maintaining reasonable structural complexity through automated control.
2Reliability
If the flash lamp position is adjusted to track objects, then light supplementation effectiveness is improved, but the device complexity increases
Solution Approach 1:
A feedback control system is implemented where the photosensitive unit continuously monitors object movement and sends detection signals to the position adjusting unit. This closed-loop feedback mechanism ensures the flash lamp accurately tracks moving objects, improving light supplementation effectiveness while managing control system complexity through automated signal processing.
Solution Approach 2:
The system achieves a degree of self-service through the photosensitive unit that automatically detects object movement and triggers position adjustments without manual intervention. The flash lamp positioning is self-regulated based on real-time detection signals, reducing the need for complex external control mechanisms.
3Adaptability or versatility
If a position adjusting unit is added to enable tracking, then object tracking capability is improved, but manufacturing complexity increases
Solution Approach 1:
The position adjusting unit is designed with multi-functionality, serving both as a mounting structure for the flash lamp and as an active tracking mechanism. By integrating the adjustment function into an existing structural component rather than adding a completely separate mechanism, the patent reduces manufacturing complexity while maintaining the tracking function.

AI summary
A method for controlling a flash lamp of a camera to provide supplemental light during image-capturing is disclosed. The flash lamp includes a lamp and a position adjusting unit, the lamp being able to track a moving target object in addition to being able to apply spotlighting or wide angle illumination of the object. The method acquires a first brightness value surrounding a target object from a photosensitive unit, compares the value with a preset value and turns on the lamp when the value is less than the preset value. The camera can detect whether the target object is moving; and the lamp can be controlled to move (by the position adjusting unit) to track the moving target object and maintain illumination of it for the image-capture.
