Abstract
An image sensor may include a substrate which includes a plurality of block regions. Each block region may include a separate plurality of pixel regions. Each pixel region may include a separate photoelectric element of a plurality of photoelectric elements in the substrate and a separate micro lens of a plurality of micro lenses on the substrate. Each micro lens of the plurality of micro lenses may be laterally offset from a vertical centerline of the pixel region towards a center of the block region. Each block region of the plurality of block regions may include a common shifted shape of the plurality of micro lenses of the block region.
Claims19
An image sensor, comprising:
- a substrate which includes a plurality of block regions, each of the block regions including a first to fifth pixel regions, the second and third pixel regions arranged in a first direction with the first pixel region interposed therebetween, and the fourth and fifth pixel regions arranged in a second direction with the first pixel region interposed therebetween, and the second direction intersecting the first direction;
- first to fifth photoelectric elements in separate, respective pixel regions of the first to fifth pixel regions;
- and
- first to fifth micro lenses on separate, respective pixel regions of the first to fifth pixel regions,
- wherein the first micro lens has a same vertical centerline as a vertical centerline of the first pixel region,
- the second micro lens is laterally offset from a vertical centerline of the second pixel region by a first interval,
- the third micro lens is laterally offset from a vertical centerline of the third pixel region by the first interval,
- the fourth micro lens is laterally offset from a vertical centerline of the fourth pixel region by a second interval, and
- the fifth micro lens is laterally offset from a vertical centerline of the fifth pixel region by the second interval.
An image sensor, comprising:
- a substrate which includes a plurality of block regions, each of the block regions including
- a center pixel region and a plurality of first peripheral pixel regions disposed around the center pixel region;
- a first photoelectric element in the center pixel region;
- a first micro lens on the center pixel region;
- a second photoelectric element in each of the first peripheral pixel regions;
- and
- a second micro lens on each of the first peripheral pixel regions,
- wherein a center of the second micro lens is shifted from a vertical centerline of each of the first peripheral pixel regions towards a center of the first micro lens,
- wherein the plurality of block regions include separate, respective sets of pixel regions, and the first and second micro lenses of the plurality of block regions are shifted in units of block regions, such that each separate block region includes a different center pixel region, a different plurality of first peripheral pixel regions, and different second micro lenses shifted towards a different first micro lens.
