Abstract
An apparatus includes a plurality of pixels and a plurality of microlenses. Each of the pixels has a first conversion unit and a second conversion unit surrounding the first conversion unit. The first conversion unit and the second conversion unit each have a light portion to receive light from a corresponding microlens. The first conversion unit and the second conversion unit are under the corresponding microlens. The pixels includes two or more pixels varying in an area ratio between an area of the light *portion of the first conversion unit and an area of the light portion of the second conversion unit.
Claims26
An apparatus comprising:
- pixels including a first pixel and a second pixel;
- and
- a plurality of microlenses,
- wherein each of the pixels has a first conversion unit and a second conversion unit surrounding the first conversion unit,
- wherein the first conversion unit and the second conversion unit each have a light portion to receive light from a corresponding microlens,
- wherein the first conversion unit and the second conversion unit are under the corresponding microlens, and
- wherein a first area ratio between an area of the light portion of the first conversion unit in the first pixel and an area of the light portion of the second conversion unit in the first pixel is different from a second area ratio between an area of the light portion of the first conversion unit in the second pixel and an area of the light portion of the second conversion unit in the second pixel.
A substrate to be on another substrate, the substrate comprising:
- pixels including a first pixel and a second pixel;
- and
- a plurality of microlenses,
- wherein each of the pixels has a first conversion unit and a second conversion unit surrounding the first conversion unit,
- wherein the first conversion unit and the second conversion unit each have a light portion to receive light from a corresponding microlens,
- wherein the first conversion unit and the second conversion unit are under the corresponding microlens, and
- wherein a first area ratio between an area of the light portion of the first conversion unit in the first pixel and an area of the light portion of the second conversion unit in the first pixel is different from a second area ratio between an area of the light portion of the first conversion unit in the second pixel and an area of the light portion of the second conversion unit in the second pixel.
