How to Improve the Image Quality of Waterproof Underwater Cameras?

Reflection problems General infrared waterproof cameras always have the problem of image flicker. What is the essence? The principle of the waterproof underwater camera is that when the camera's illumination intensity is below the threshold, the infrared lamp turns on and emits light, and above the threshold, it turns off. 

When the illumination intensity is slightly lower than the threshold value, the photosensitive element detects that the illumination intensity is slightly lower and will control the infrared lamp to turn on. After the infrared lamp emits light, the detected illuminance increases (water And the protective cover will reflect a large amount of infrared light), and beyond the threshold, the infrared lamp is turned off-resulting in a decrease in the detected illumination, and the infrared lamp is turned on again. This non-stop alternation causes the image to flicker. When this happens, it is necessary to work on the photosensitive element of the infrared waterproof camera.

1. Change the threshold

At the same time, there are discrete thresholds in the model products, which are also different. Therefore, manufacturers provide products with different design thresholds, which can be tried and replaced. Waterproof underwater cameras use products with larger threshold design parameters, and there is less possibility of flicker some.

2. Change the environment

Change the intensity and angle of the lighting. Change the installation angle of the infrared waterproof camera a little, and the illuminance detected by the detector will leave near the threshold, thus solving the flicker problem.

3. Change the chip

Use high-quality low-illumination camera chips with backlight compensation and anti-glare, especially dedicated IR lenses.

The heat generated by the traditional infrared waterproof underwater camera is transmitted through the positive periodicity, which does not play a role in heat dissipation. The packaging material is epoxy resin, and the working decomposition will cause a fracture layer, resulting in the phenomenon of light attenuation After a month, the traditional infrared waterproof camera can be attenuated by 30%. In order to change the situation that the life of infrared waterproof cameras is not long due to poor heat dissipation, the new generation of infrared waterproof cameras currently produced has made innovations and improvements in infrared lights.
