Low-light imaging refers to the ability to capture images in conditions where light is limited, such as at dusk or indoors. This technology is commonly used in cameras and smartphones, allowing users to take clear photos without using a flash. Low-light imaging often employs larger sensors and advanced algorithms to enhance brightness and reduce noise in the final image. Techniques like long exposure and infrared imaging are also part of low-light imaging. These methods can reveal details that are not visible to the naked eye. Applications include wildlife photography, security surveillance, and astronomy, where capturing faint light sources is essential.
