The method is adapted to a 4-cell sensor and can automatically calculate appropriate compensation parameters for fixed pattern noise according to non-uniformity of the sensor and lens.

Afterwards, a fixed pattern noise compensation coefficient of every pixel can be calculated according to characteristics of the image formed by the 4-cell sensor. In one aspect, the compensation coefficient of the current pixel can be calculated by extrapolation or interpolation. The fixed pattern noise in the image can be corrected.
