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.
Claims20
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.
