1. A method for processing an image, comprising:

  • providing a sensor output;

    performing an automatic gain control of the sensor output to generate a first output;

    performing an automatic white balance correction to the first output to generate a second output;

    performing a gamma correction of the second output to generate a third output;

    performing a color interpolation to the third output to generate a fourth output;

    performing a low-pass spatial filtration of the fourth output to generate a fifth output;

    performing a color saturation and correction of the fifth output to generate a sixth output; and

    performing a high-pass spatial filtration of the sixth output to generate an image output.
