Abstract
According to an embodiment, a color filter array includes a plurality of color filters of multiple colors. The color filters are arranged so that each of the color filter of each color corresponds to any one of a plurality of microlenses included in a microlens array. Each microlens is configured to irradiate a plurality of pixels with light.
Claims17
A color filter array comprising a plurality of color filters of multiple colors, wherein
- the color filters are arranged so that the color filter of each color corresponds to any one of a plurality of microlenses included in a microlens array, each microlens being configured to irradiate a plurality of pixels with light, wherein
- the color filters are arranged in a hexagonal lattice, and
- a set of one color filter of a first color, two color filters of a second color, and one color filter of a third color sequentially arranged adjacent to one another in a line is repeated along the line, and the set is repeated adjacent to the line with a shifted amount of 1.5 filters.
A solid-state image sensor comprising:
- a color filter array;
- a microlens array;
- and
- an image sensor irradiated with light through the color filter array and the microlens array, and
- a main lens that guides light from an object to the microlens array and the image sensor, wherein
- the color filter array includes a plurality of color filters of multiple colors,
- the color filters are arranged so that each color filter of each color corresponds to any one of a plurality of microlenses included in a microlens array, each microlens being configured to irradiate a plurality of pixels with light,
- the color filters are arranged in a hexagonal lattice,
- the color filters are arranged in a manner that at least two color filters of a same color from among the color filters arranged adjacent to one color filter are arranged non-point-symmetrically with respect to the one color filter,
- the main lens is arranged at a position such that an image plane is separate from the microlens array and on a side facing one of the object and the image sensor, and
- the microlens array is arranged such that an image through each of the plurality of microlenses is focused at each area of the color filters of multiple colors.
A color filter array comprising a plurality of color filters of multiple colors, wherein
- the color filters are arranged so that the color filter of each color corresponds to any one of a plurality of microlenses included in a microlens array, each microlens being configured to irradiate a plurality of pixels with light, wherein
- the color filters are arranged in a hexagonal lattice, and
- a set of one color filter of a first color, three color filters of a second color, and one color filter of a third color sequentially arranged adjacent to one another in a line is repeated along the line and the set is repeated adjacent to the line with a shifted amount of 1.5 filters.
