we have already seen the Canon Patent Five Layer Sensor, and also a Three-Layer sensor from Canon, But today a new patent surfaced over the web that shows a thin anti-reflection film added between each layer of the sensor to absorb the ghost and flare generated by the reflection of light, take a look at the details below (translated by google)
Description and self-interpretation of the patent literature
- Patent Publication No. 2014-130890
- Publication date 2014.7.10
- Filing date 2012.12.28
- Multilayer sensor drawback of
- G is light, the image quality is degraded and reflected by the surface of the layer between the G and B layer, re-enters the B layer
- Canon patents
- The provision of the dielectric film and the insulating film as an anti-reflection film
- First insulating layer, B layer, a dielectric film, insulating film, dielectric film, G layer, a dielectric film, insulating film, insulating film, dielectric film, the R layer
- By increasing the thickness of the dielectric film, to suppress the multiple reflection
- The dielectric film is between the G layer and B layer, the reflectance with respect to G is lower than B
