Abstract
A NB-cam module calibration method is provided. The method includes the following steps: an image which the optical lens of each NB-cam module spotlights onto a light sensor of each NB-cam module is calibrated to generate a compensation parameter set corresponding to each NB-cam module; a color temperature table within the compiled lens-driver firmware is modified according to each compensation parameter set; and the compiled and modified lens-driver firmware is directly burned to each NB-cam module.
