Photosensitive sensor and applications in the automotive field
First Claim
1. A sensor photosensitive in relation to at least part of the radiation in the infrared and at least part of the radiation in the visible range, wherein the sensor comprises a filter affecting all or part of a receiving zone of the sensor and able to filter radiation in wavelengths to which the sensor is sensitive according to a degree of filtering that varies locally;
- wherein said receiving zone comprises a plurality of zones, said filter providing infrared filtering of different levels to said plurality of zones;
wherein said filter filters only a top portion or a bottom portion of said receiving zone, which corresponds to a bottom part of the object or scene.
