Sony is working on new sensor designs (patent disclosure)

One of the latest Sony patents disclosed a new kind of sensor. Pixel size does change based on their color characteristic. This does make sense because every color has a different sensivity. Read the google english translation:

  • Patent publication number 2010-129548
    • 2010/06/10 Release date 2010/06/10
    • 2008/11/25 Filing Date November 25, 2008
  • Current Issues
    • The signal level is smaller and more pixelated, S / N ratio is difficult to ensure
    • RGB wavelengths the energy profile for each file is different
  • Patent Technology
    • Energy profiles corresponding to the active area (pixel size) and
    • Long wavelength light (Red) is a large photodiode (detector sensors) and
      • Silicon on the substrate, R is the weakest of the irradiation energy
      • RGbGrB square fit to
  • Consider the type and surface radiation exposure type back
  • Bayer employs
  • Pixel pitch of 1.1μm (back radiation) 2.5μm and (irradiated surface) examined
