Abstract
An image sensing device includes a plurality of pixel groups, each pixel group including first to fourth unit pixels that are configured to respond to incident light and generate electrical signals, and wherein each of the first to fourth unit pixels of a pixel group includes optical filters operable to transmit incident light corresponding to a same color, wherein the first unit pixel and the second unit pixel that are included in the pixel group are located adjacent to each other and include portions of a first microlens, and wherein a light reception area of the third unit pixel of the pixel group has a size smaller than a size of a light reception area of the fourth unit pixel of the pixel group.

An image sensing device, comprising:
- a plurality of pixel groups, each pixel group including first to fourth unit pixels that are configured to respond to incident light and generate electrical signals, and
- wherein each of the first to fourth unit pixels of a pixel group includes optical filters operable to transmit incident light corresponding to a same color,
- wherein the first unit pixel and the second unit pixel that are included in the pixel group are located adjacent to each other and include portions of a first microlens, and
- wherein a light reception area of the third unit pixel of the pixel group has a size smaller than a size of a light reception area of the fourth unit pixel of the pixel group.
An image sensing device, comprising:
- a pixel array including pixel groups, each pixel group including unit pixels arranged in a (2×2) matrix and configured to respond to incident light and generate a signal corresponding to the incident light;
- and
- a processor electrically coupled to the pixel groups and configured to process the signal generated by unit pixels included in the pixel groups,
- wherein each pixel groups further includes:
- first to fourth unit pixels that include optical filters configured to transmit incident light of a same color;
- a microlens disposed to overlap with the first unit pixel and the second unit pixel, and
- wherein a light reception area of the third unit pixel has a size smaller than a size of a light reception area of the fourth unit pixel,
- wherein the processor is configured to generate phase difference data indicative of a phase difference between a first path for the incident light to reach the first unit pixel and a second path for the incident light to reach the second unit pixel.
