Title: The Innovations of Roberto Rambaldi
Introduction
Roberto Rambaldi is a notable inventor based in Bologna, Italy. He has made significant contributions to the field of image sensor technology, holding a total of 6 patents. His work focuses on enhancing the performance and reliability of CMOS image sensors.
Latest Patents
One of Rambaldi's latest patents is a pixel correction system and method for CMOS imagers. This invention discloses a fault-tolerant CMOS image sensor that includes circuitry for identifying defective pixels and masking them during image generation. The masking process may involve replacing the output of a given pixel with an average of the output of surrounding non-faulty pixels. This innovation ensures that images produced by such sensors do not exhibit undesirable bright or dark spots, even when some pixels are faulty. The disclosed sensor comprises one or more pixels capable of providing outputs indicative of the quantity of radiation to which each pixel has been exposed. Additionally, it includes circuit elements configured to identify and correct faulty pixels in the CMOS imager. The sensor can also identify pixels that were initially acceptable but later became defective, thereby increasing the CMOS detector's lifetime.
