Automatic Exposure Control (AEC)

Automatic Exposure Control (AEC) is a feature in imaging devices like cameras and X-ray machines that automatically adjusts the amount of light or radiation to produce a well-exposed image. It detects the available light or radiation hitting the sensor or film and modifies the exposure duration or intensity accordingly. This ensures the image isn’t too dark or too bright, resulting in clear, properly exposed pictures or diagnostic images without requiring manual adjustments. In medical imaging, AEC helps optimize image quality while minimizing patient radiation dose.
