Automatic Brightness Control | Optics Trade Debates

  • Polona 

Welcome to Optics Trade debates. In each episode, we talk about a different topic and try to answer the most common questions we receive about it. Today we are going to talk about automatic brightness control.

Automatic brightness control and bright light cut-off are features which can be found on night vision devices. Automatic brightness can be found on digital and analog devices, while bright light cut-off can be found only on analog NV devices.

Automatic brightness control is an advanced feature of a bright light cut-off. If an NV device has bright light cut-off and is hit with a bright artificial light source, the analog cathodes amplify the artificial light source in a different ratio than the darkness around it. It has a „mode“ for complete darkness and a „mode“ for bright light. This function protects the user’s eye and the device itself. We went into more detail in another segment

Automatic brightness control is a similar system, but it regulates the brightness several times a second. The software adjusts the level of the light amplification. It always regulates the amplification of light for the optimal image quality.

This function is common in high-quality third generation and generation 2+ devices. The function is really precise so that the image is always optimal. It’s a very important feature in analog NV devices because it protects the user’s eyes and the cathode in the device. Its main purpose in digital devices is to achieve a better image quality.

Automatic brightness control achieves a better image quality in all situations on both types of devices.

Different digital NV manufacturers have different names for automatic brightness control because it’s purely a software solution.

The automatic brightness control is found on all digital devices and only on premium analog devices.
