What is sensitivity of cmos image sensors?

The sensitivity of CMOS image sensors refers to their ability to detect and respond to low levels of light. This sensitivity is influenced by factors such as pixel size, sensor architecture, and the quality of the photodiodes used. Generally, larger pixels can capture more light, improving sensitivity, while advancements in technology have led to improved noise reduction and dynamic range, enhancing performance in low-light conditions. Overall, higher sensitivity allows for better image quality in various lighting environments.
