Abstract:
1. A method for correcting pixel information of color pixels on a color filter array of an image sensor, the color filter array including a plurality of pixel arrays, each pixel array consisting of a four (4) N×N pixel units, N being an integer equal to or larger than 2, each N×N pixel unit having a plurality of white pixels and at least one color pixel, the at least one color pixel including one or more red pixels, one or more green pixels, one or more blue pixels, or any combination thereof, the number of the at least one color pixel in each of the four (4) N×N pixel units being the same, the number of the at least one color pixel in each of the four (4) N×N pixel units being smaller than the number of the plurality of white pixels in each of the four (4) N×N pixel units, the method comprising: establishing an M×M distance factor table having M×M distance factors (d selecting M×M pixels of the color filter array, wherein the M×M pixels of the color filter array cover at least two red pixels, at least two green pixels, at least two blue pixels, and a target pixel, and the target pixel is a center pixel of the M×M pixels of the color filter array; calculating a red-color contribution (R calculating a green-color contribution (G calculating a blue-color contribution (B calculating at least one of a red-color pixel performance (f calculating at least one of a red-color correcting factor (T performing at least one of
