Leveraging New CMOS Technology in Global Security Systems
The global security industry is increasingly shifting from charge-coupled device (CCD) to complementary metal-oxide-semiconductor (CMOS) daylight cameras, driven by the enhanced low-light performance of recent CMOS global shutter image sensors. These advancements include improved near-infrared (NIR) sensitivity and reduced noise, making CMOS a more reliable choice for various lighting conditions.
Key Advantages of Modern CMOS Sensors
-
Superior Low-Light Performance: The latest CMOS sensors offer better sensitivity to NIR light and lower noise levels, significantly improving image quality in dim environments compared to traditional CCD cameras.
-
Adaptive Resolution Capabilities: New CMOS daylight cameras feature adaptive resolution technology, allowing them to adjust image clarity based on lighting conditions without requiring changes to the optical system.
-
Small Pixel Size for Space-Saving Designs: With smaller pixel sizes, these sensors enable camera manufacturers to create compact devices while maintaining high-resolution imaging capabilities. This eliminates the need to replace existing optics when upgrading older cameras.
Practical Applications
- Auto White Balance Color Imaging: In changing lighting conditions, modern CMOS cameras can automatically adjust color balance for accurate and natural images.
- Industry Demonstrations: At events like SPIE DCS 2016 and SPIE Defense, Security, and Sensing 2016, several articles discussed how to effectively utilize these technologies in low-light global security applications.
Example: IMX250-Based TMX50 Color Imaging
A notable example is the use of the IMX250 sensor in the TMX50 camera, which demonstrates exceptional color rendering even under challenging light conditions. This highlights how CMOS technology can deliver high-quality imagery without compromising on performance or size.
By embracing these innovations, security professionals can enhance surveillance systems with more reliable and efficient imaging solutions.
