Abstract
A color filter array for an image sensing device includes a plurality of pixels, for generating a plurality of pixel data of an image; and a control unit, for controlling the plurality of pixels; wherein each of the plurality of pixels is divided into a plurality of sub-pixels; wherein the pixel data outputted by each of the plurality of pixels is generated based on at least one pixel value of the plurality of sub-pixels and the outputted pixel data is smaller than a saturated threshold; wherein at least one pixel in the plurality of pixels has a mixed color by having different sub-pixel colors in the plurality of sub-pixels.
Claims12
A color filter array for an image sensing device, the color filter array comprising:
- a plurality of pixels, for generating a plurality of pixel data of an image;
- and
- a control unit, for controlling the plurality of pixels;
- wherein each of the plurality of pixels is divided into a plurality of sub-pixels;
- wherein the pixel data outputted by each of the plurality of pixels is generated based on at least one pixel value of the plurality of sub-pixels and the outputted pixel data is smaller than a saturated threshold;
- wherein at least one pixel in the plurality of pixels has a mixed color by having different sub-pixel colors in the plurality of sub-pixels.
A method of manufacturing a color filter array, which is used for generating a plurality of pixel data of an image, the method comprising:
- forming a plurality of pixels of the color filter array;
- dividing each of the plurality of pixels into a plurality of sub-pixels with the same pixel color;
- and
- altering sub-pixel colors of the plurality of sub-pixels in at least one pixel of the plurality of pixels to be different, to make the at least one pixel have a mixed color;
- wherein each of the plurality of pixels accumulates pixel value of at least one of the plurality of sub-pixels in each of the plurality of pixels as the pixel data outputted by each of the plurality of pixels.
