Pixel, pixel array, and image sensor including the pixel array
Disclosed are a pixel, a pixel array, and an image sensor including the pixel array. The pixel includes a first photo-sensing unit to detect a visible light and an IR, and a second photo-sensing unit provided at one side of the first photo-sensing unit to detect a light in which the IR is blocked.
1. A pixel comprising:
a first photo-sensing unit to detect a visible light and an IR; and
a second photo-sensing unit provided at one side of the first photo-sensing unit to detect a light in which the IR is blocked,
wherein the first photo-sensing unit comprises:
a first visible light sensing unit to detect the visible light; and
a first IR sensing unit to detect the IR between the first visible light sensing unit and a substrate, and
wherein the second photo-sensing unit comprises:
a second visible light sensing unit to detect the visible light; and
an IR blocking unit to block the IR between the second visible light sensing unit and the substrate.
2. The pixel of claim 1 , wherein a signal having a visible band is independently distinguishable from a signal having an IR band due to a signal difference between the first and second photo-sensing units.
3. A pixel array having the pixel claimed in claim 2 .
4. An image sensor comprising a pixel array, wherein the pixel array comprises the pixel claimed in claim 2 .
5. A pixel array having the pixel claimed in claim 1 .
6. An image sensor comprising a pixel array, wherein the pixel array comprises the pixel claimed in claim 1 .
