What feature does a day/night functional camera utilize during night operation?

• A. Fixed IR exposure
• B. Enhanced color filters
• C. Removable IR filter
• D. Permanent UV protection

Answer: (C)

A day/night functional camera is designed to operate efficiently in varying light conditions, particularly transitioning from daylight to nighttime settings. During night operation, these cameras utilize a removable infrared (IR) filter to enhance their ability to capture clear images in low-light environments. In daylight, the IR filter is in place to prevent infrared light from entering the camera, which can distort colors and affect image quality. However, when the light diminishes, the camera can automatically remove this filter, allowing infrared light to be captured effectively. This capability is crucial for night vision since many of the available light sources at night are within the infrared spectrum, and removing the filter maximizes the sensitivity of the camera's sensor. This functionality enables the camera to display improved contrast and clarity in images taken during nighttime, which is the primary advantage of the day/night feature. Hence, the correct choice emphasizes the camera's adaptability and effectiveness in varying light conditions by using a removable IR filter.
