Abstract: A zooming camera module includes a first lens group, a second lens group, and a third lens group. The first lens group is implemented on an optical axis at a fixed position, and has a negative total optical power. The second lens group is implemented on the optical axis and can be moved back and forth along the optical axis, to achieve zooming and focusing. The second lens group has a positive total optical power, and includes a liquid lens unit and at least one lens with non-zero optical power, wherein the at least one lens and the liquid lens are separately or integrally configured. The third lens group is implemented on the optical axis at a fixed position, and has a non-zero total optical power.

Abstract: An auto-focusing lens module includes an object lens, a liquid zooming unit, and an image lens group. The object lens and the liquid zooming unit receive an object image in front and condense the image into a first-stage output light. A zoom quantity is determined by an external control on the liquid zooming unit. The image lens group including a first and second lens receives the first-stage output light to transmit a second-stage output light. The first lens has a first and second surface, in which the second surface is farther than the first surface to the liquid zooming unit and has a convex curving surface protruding toward an image sensor. The second lens has a first and second surface, in which the first surface has a concave curving surface indenting toward the image sensor to adapt at least a portion of the convex curving surface of the first lens.

Abstract: A method for designing and manufacturing lens modules includes selecting design parameters from a design database stored with the design parameters suitable for a lens module desired to be manufactured to design the lens module according to characteristics of the lens module and storing the design parameters of the lens module in an analysis database, analyzing the lens module based on a predetermined analysis process to generate analysis parameters corresponding to the lens module and storing the generated analysis parameters in the analysis database, and re-designing the lens module based on the analysis parameters stored in the analysis database.
