IMAGE CAPTURING MODULE FOR SAVING FOCUSING TIME AND INCREASING ASSEMBLY FLATNESS AND METHOD OF ASSEMBLING THE SAME

摘要

An image capturing module for saving focusing time and increasing assembly flatness and a method of assembling the same are disclosed. The image sensing chip has a first horizontal top surface, the optical filter has a second horizontal top surface, and the first horizontal top surface and second horizontal top surface are obtained by a horizontal correction system using a laser light source. The distance from the second horizontal top surface to the first horizontal top surface is defined as a predetermined fixed focusing distance. Whereby, the movable lens assembly is directly disposed on the second horizontal top surface to save the focusing time of the movable lens assembly relative to the image sensing chip, and the first horizontal top surface and the second horizontal top surface are horizontal to each other for increasing the assembly flatness of the movable lens assembly relative to the image sensing chip.
