Peter Brian Denyer (27 April 1953 – 22 April 2010) was a British electronics engineer, academic, scientist, inventor, and entrepreneur who pioneered CMOS image sensor chips for many applications including mobile phones, webcams, video-conferencing cameras, and optical computer mouse.
"Undoubtedly, his greatest legacy...was his work in fitting mini-cameras in mobile phones." wrote the Herald Scotland.
From an EE professorship at the University of Edinburgh, he went on to found VLSI Vision Inc., later known as VISION Group plc, an early maker of CMOS image sensors that sold itself to STMicroelectronics.
The first academic to grow a Scottish university spin-out company to PLC, he was described by the Royal Society as "a unique combination of electronics engineer, distinguished academic, inventor, company CEO and multiple entrepreneur.""To say that Denyer 'invented' the mobile phone camera," wrote one obituarist, "would be unfair to the rest of his research team at the University of Edinburgh and to parallel researchers worldwide....But, although the camera phone phenomenon was but a twinkle in Denyer's eye when he started out, he became internationally recognised as a driving force in the technology known as CMOS (complementary metal-oxide semiconductor) which still features in hundreds of millions of mobile phones around the globe."
