Abstract
An image sensor includes a pixel array in which auto-focus (AF) pixels and image capture pixels are arranged. Wherein at least one of the AF pixels comprises: a color filter layer; and first and second microlenses arranged over the color filter layer, and formed in a region of the at least one AF pixel in a widthwise direction of the color filter layer.
Claims21
An image sensor comprising a pixel array in which auto-focus (AF) pixels and image capture pixels are arranged,
- wherein at least one of the AF pixels comprises;
- a color filter layer;
- and
- first and second microlenses arranged over the color filter layer, and formed in a region of the at least one AF pixel in a widthwise direction of the color filter layer,
- wherein the at least one AF pixel comprises a pair of AF pixels for detecting a phase difference,
- the first and second microlenses of one AF pixel of the pair of AF pixels are formed symmetrically with respect to the first and second microlenses of the other AF pixel of the pair of AF pixels.
(canceled)
An image sensor comprising a pixel array in which auto-focus (AF) pixels and image capture pixels are arranged,
- wherein at least one of the AF pixels comprises:
- a color filter layer;
- and
- a receiving layer and a microlens arranged over the color filter layer, and formed in a region of the at least one AF pixel in the widthwise direction of the color filter layer,
- wherein the at least one AF pixel comprises a pair of AF pixels for detecting a phase difference,
- the receiving layer and the microlens of one AF pixel of the pair of AF pixels are formed symmetrically with respect to the receiving layer and the microlens of the other AF pixel of the pair of AF pixels.
(canceled)
An image sensor comprising a pixel array in which auto-focus (AF) pixels and image capture pixels are arranged,
- wherein at least one of the AF pixels comprises:
- a color filter layer;
- and
- first and second light-incident layers arranged over the color filter layer,
- wherein the first and second light-incident layers have different heights and different widths,
- wherein the at least one AF pixel comprises a pair of pixels for detecting, a phase difference,
- the first and second light-incident layers of one AF pixel of the pair of AF pixels are formed symmetrically with respect to the first and second light-incident layers of the other AF pixel of the pair of AF pixels.
