Camera Light Supplementing With Side-Sensor Pre-Entry Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with cameras, such as video cameras and mobile phones, face increased power consumption when the light supplementing apparatus is constantly activated, especially in low ambient illumination, which reduces the device's endurance time.
Innovation Solution
A light supplementing apparatus with sensor modules on both sides of the camera, biased to detect objects before they enter the visual field, triggering the light only when needed, reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the light supplementing apparatus is always kept on to improve photographing picture quality in low ambient illumination, then the camera can clearly recognize the object, but the power consumption of the device with a camera increases
Solution Approach 1:
The sensor unit is positioned to detect target objects before they enter the camera's photographing visual field. This preliminary detection triggers the light supplementing lamp to activate in advance, ensuring that lighting is already available when the target enters the visual field, thereby maintaining picture quality without requiring continuous illumination
Solution Approach 2:
The system establishes a feedback control loop where the sensor unit continuously monitors the environment for target objects, and based on detection results, the system controller adjusts the state of the light supplementing lamp. This feedback mechanism ensures the lamp is activated only when and where needed, optimizing both picture quality and power consumption
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively reduces power consumption by selectively activating the light supplementing lamp, enhancing the device's endurance and improving picture quality in low light conditions.
Implementation Method 1
the first sensor being a passive infrared radiation (PIR) sensor or a radar sensor
Implementation Method 2
the second sensor being a PIR sensor or a radar sensor
Implementation Method 3
the light supplementing lamp being configured to emit light toward the photographing visual field of the camera

AI summary
The present application discloses a light supplementing apparatus for a device with a camera and a device with a camera. The light supplementing apparatus is provided with two sensor modules on two horizontal sides of a camera, and detection directions of the two sensor modules are horizontally and reversely biased with respect to a photographing direction of the camera so that an overall detection range of the two sensor modules is larger than the photographing range of the camera. Thus, when the ambient illumination is low, the device with a camera may recognize a target object through the two sensor modules and turn on a light supplementing lamp only before the target object is about to enter a photographing visual field of the camera, instead of having to turn on the light supplementing lamp all the time, which reduces the power consumption of light supplementing.
