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.
