Abstract
Provided is an image sensor. The image sensor may include a plurality of first lenses disposed on a substrate, and a plurality of second lenses disposed on a structure disposed on the substrate suitable for changing the distance between the first and second lenses from a first minimum distance wherein the image sensor operates in a first mode to a second maximum distance wherein the image sensor operates in a second mode.
Claims20
An image sensor, comprising:
- a plurality of first lenses disposed on a substrate;
- and
- a plurality of second lenses disposed on a structure disposed on the substrate suitable for changing a distance between the first and second lenses from a first minimum distance where the image sensor operates in a first mode to a second maximum distance where the image sensor operates in a second mode.
An image sensor, comprising:
- a substrate having a pixel area and a peripheral area surrounding the pixel area;
- color filters and microlenses suitable for being disposed on the substrate corresponding to the pixel area;
- a supporting plate disposed on the substrate corresponding to the peripheral area;
- lower electrode posts and upper electrode posts disposed on the supporting plate;
- a lower electrode plate horizontally disposed on the lower electrode posts;
- an upper electrode plate horizontally disposed on the upper electrode posts;
- and
- light field lenses disposed on the upper electrode plate,
- wherein the upper electrode plate is suitable for moving so that an interval between the lower electrode plate and the upper electrode plate is changed.
