Canon patent
- Back-illuminated imaging device
- Plurality of light receiving portion is provided in the order BGR
- In one pixel, the charge collection in the center section, provided the charge read to the end
- Focusing capabilities of the microlenses, light in the center of the charge collection has increased, the charge read out at the end of the light is reduced
- Therefore, in reading the charge of B, it becomes difficult to receive light G, to prevent mixing
- Widest area of B. By mixing pixels with narrow spacing of the pixels (light receiving portion for receiving the G colored in B) to prevent
- Read the charge and B matches the central microlens. And easy to read the charges received by B, to prevent mixing
- Improve performance by preventing the mixing color separation
