Abstract
A high dynamic range sensing device is disclosed. The device includes an array of Bayer pattern units. Each of the Bayer pattern units comprises a plurality of pixels and each of the plurality of pixels comprises a plurality of photodiodes. At least one of the plurality of photodiodes in each pixel is configured to detect near infrared (NIR) light and at least one of the plurality of photodiodes in each of the plurality of pixels is configured to detect visible light.
Claims17
A sensing device, comprising
- an array of Bayer pattern units, wherein
- each of the Bayer pattern units comprises a plurality of pixels;
- each of the plurality of pixels comprises a plurality of photodiodes;
- at least one of the plurality of photodiodes in each pixel is configured to detect non-visible light;
- at least two of the plurality of photodiodes in each of the plurality of pixels is configured to detect visible light;
- and
- in each of the plurality of pixels, a single red, green, or blue filter covers the at least two photodiodes configured to detect visible light.
4 more elements
A sensing device, comprising
- an array of optical filter combinations, each of the optical filter combinations corresponding to a pixel of the sensing device and having at least two different filters,
- and each of the optical filter combinations associated with a plurality of photodiodes;
- one of the filters is a single red, green, or blue filter covering a plurality of photodiodes configured to detect visible light;
- and
- one of the filters is a non-visible light filter covering a photodiode configured to detect non-visible light.
2 more elements
A sensing device, comprising
- a plurality of pixels, each comprising four photodiodes, at least two of the photodiodes in each pixel being configured to detect visible light, and at least one of the photodiodes in each pixel being configured to detect non-visible light;
- and
- in each pixel, a single red, green, or blue filter covers the plurality of photodiodes configured to detect visible light.
