Abstract: The present invention provides a reduced-height image-capturing module, which includes a lens assembly, an image-sensing chip, a carrier base and a circuit substrate. The carrier base has a base body, two extending plate bodies extending and a base groove recessed. A lower portion of the base body enters a through opening of the circuit substrate, and the two extending plate bodies cross over the through opening of the circuit substrate and are disposed on an upper surface of the circuit substrate. The image-sensing chip is disposed on a recessed bottom surface of the base groove which is not at the same level as the upper surface of the circuit substrate, so that the recessed bottom surface is lower than the upper surface of the circuit substrate. The lens assembly is disposed on the upper portion of the base body and corresponds to the image-sensing chip.

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.
