HAD CCD is a Sony charge-coupled device (CCD) image sensor technology based on a hole accumulation diode (HAD), a sensor structure designed to suppress certain types of noise inherent to CCDs.
List of HAD CCD sensors
 |
Sony described HAD designs as offering low noise and strong low-light sensitivity. Related Sony branding included Super HAD implementations intended to improve low-light performance and reduce fixed-pattern noise in low-light shooting, as well as EXview HAD CCD variants for high-sensitivity shooting.
