The ISP converts the raw image delivered by the sensor into a processed image after analog-to-digital conversion.
A defect pixel list enables interpolation to eliminate defects. A flat field image reduces fixed pattern noise. A demosaicing algorithm converts the Bayer pattern into a trichromatic color image, and a color correction matrix or look-up table converts the raw colors into the correct ones.
These are just a few examples of the many parameters that can be adjusted in the ISP to optimize camera performance.
Measuring image quality factors provides a basis for optimal ISP tuning.
Image Engineering can provide the necessary equipment and test services for tuning.
