Claim Text:
1. An image capturing module for increasing assembly flatness and shortening focusing time, comprising: an image sensing unit including a carrier substrate and an image sensing chip disposed on the carrier substrate and electrically connected to the carrier substrate, wherein the image sensing chip has a first horizontal top surface on the top side thereof, and the first horizontal top surface is obtained by a horizontal correction system using a laser light source; a housing frame disposed on the carrier substrate to surround the image sensing chip; an actuator structure disposed on the housing frame and above the image sensing chip, wherein the actuator structure includes a lens holder disposed on the housing frame and a movable lens assembly disposed inside the lens holder and above the image sensing chip, the lens holder includes a surrounding movable member movably disposed therein, the movable lens assembly is fixed inside the surrounding movable member through at least two separate bonding glue, and the movable lens assembly is movably disposed inside the lens holder through the surrounding movable member; and a reflecting material temporarily placed on the top side of the movable lens assembly, wherein the reflecting material has a second horizontal top surface on the top side thereof, and the second horizontal top surface is obtained by the horizontal correction system using the laser light source; wherein the first horizontal top surface of the image sensing chip and the second horizontal top surface of the reflecting material are horizontal to each other, for increasing the assembly flatness of the movable lens assembly relative to the image sensing chip; wherein the distance from the laser light source to the first horizontal top surface of the image sensing chip is defined as a first vertical distance, the distance from the laser light source to the second horizontal top surface of the reflecting material is defined as a second vertical distance, and a predetermined fixed focusing distance from the second horizontal top surface of the reflecting material to the first horizontal top surface of the image sensing chip is obtained by subtracting the second vertical distance from the first vertical distance, for shortening the focusing time of the movable lens assembly relative to the image sensing chip.
