IMAGE SENSOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18379426 titled 'IMAGE SENSOR
The abstract describes an image sensor with a substrate containing a pixel region and an optical black region, including a dummy pixel region next to the pixel region. The sensor has a first color filter array on the pixel region and a second color filter array on the dummy pixel region. The second color filter array includes a first filter transparent to a first ray and a second filter transparent to a second ray.
- Image sensor with pixel and optical black regions on a substrate
- Dummy pixel region adjacent to the pixel region
- First color filter array on the pixel region
- Second color filter array on the dummy pixel region
- Second color filter array includes filters transparent to specific rays
