CMOS, Complementary metal-oxide-semiconductor, is one of the logic families used in the manufacture of integrated circuits. An Active Pixel Sensor (APS) is a sensor able to detect light based on CMOS technology.

Thanks to CMOS technology, it is possible to integrate a range of functions into a sensor chip, such as luminosity control, a contrast corrector or an analogue-digital converter.

Advantages of CMOS:

  • Much lower electricity consumption
  • Economical (requires few external components)
  • Simultaneous reading of a higher number of pixels
  • The digital converter can be integrated into the chip itself
  • Little or no Blooming (“Smear”)
  • Greater reading flexibility (faster pre-view, video)
  • Pixels of different size and sensitivity can be combined


An effective digital imaging system must have a number of fundamental characteristics able to respond to the everyday needs of a dental clinic: quick, accurate diagnosis, space-saving size, optimisation of work time, flexibility for the user, information safety.

With this in mind, Trident has developed the I-VIEW CMOS intraoral sensor, a tool designed to optimise work time and results by allowing the doctor or dentist to make a quick, accurate diagnosis.
