In Canon’s latest patent, we can see that Canon is working to improve the low-light sensitivity of their sensors, specifically with dense photodiode architecture. This becomes particularly important when pixel sizes decrease and pixel count increases, as is the case with higher-resolution sensors. It’s a significant challenge for camera makers to maintain proper low-light sensitivity under these conditions. To overcome this, Canon is developing new technology to enhance the performance of its sensors.
Canon Latest Patent Summary
- Introducing a light shielding layer in the optical waveguide around each pixel to prevent light leakage and color mixing between pixels, and to preserve phase difference information.
- Forming an optical waveguide from near the surface of a photoelectric conversion unit to the upper end of an insulating film to prevent light scattering and absorption by wiring inside the pixel.
- Adjusting the refractive index of a non-reflective film on the bottom surface of the optical waveguide of a pixel corresponding to each color to manage variations in light receiving sensitivity between colors.
